Life Cycle of Rhizopus stolonifer Mug

So I was making some nerdy mugs for Christmas and I realized that mugs are specially suited to cycles of various sorts (eg Kreb's cycle, life cycles). Seeing as I'm interested in the zygotic meiosis life cycle, which is of course pretty much the opposite of how the human life cycle works. Anyway, a good candidate for that is the black bread mould, Rhizopus stolonifer.

So yes, I drew the (simplified) life cycle of R. stolonifer on my mug.

I used a ceramic pen and the result is dishwasher-safe. I rather love it.

What I see when I use it

Composite image showing all of the stages depicted
It's of course quite obvious that I've simplified the sexual reproduction part; I haven't tried to depict karyogamy, mostly due to space constraints. I also haven't shown the asexual reproduction which could be occurring at the same time as the sexual reproduction (so the two mating types that I've indicated would also be producing spores).

I'm quite fond of this mug.

Fern Spores - Spores de fougères

While I was out doing a field laboratory (data collection for field succession) in Gatineau Park, I noticed that the ferns were producing their spores. I find the spores both pretty and interesting. These spores are haplid (n) and will grow into individual plants which will then produce diploid (2n) reproductive cells which grow into the ferns we see here.

Genus Acer - Fall Colours

Went walking with E. along the Eardley Escarpment over the weekend. The fall colours are particularly spectacular this year and just getting started. The maples (genus Acer) tend to start changing colours first.

Surprisingly little poplar (genus Populus) on our walk, so none of the early yellows that they provide are shown here. Sorry about that. They're more common a bit further North than the Eardley Escarpment, which is basically the Southernmost tip of the boreal forest (and Canadian Shield).

Looking East along the Eardley Escarpment
There are some great walking trails in Gatineau Park, one of which meanders along the top of the escarpment, providing a number of opportunities to look out to the South.

Acer rubrum - red maple - just starting to turn
Acer saccharum - sugar maple - in peak colour
The maples set the hills ablaze, brilliant and transient against the smooth blue sky.

Bur-Reed - Sparganium erectum

Les fruits du Sparganium erectum sont extrèmement distinctes; la boule couverte de genre d'épines ne se prend pas facilement pour autre chose. Je suis tellement occupée les dernières semaines que je n'ai pas pu rien écrire ici. Mes excuses. La vie ne laisse pas toujours du temps de loisir. J'adore mon nouveau programme et je suis contente d'avoir aussi un bon emploi comme assistante de recherche.

La plante présentée ci-dessous pousse dans les marais et est génétiquement proche aux quenouilles. Les espèces variées du Sparganium sont communes dans la région; je peux en compter trois par mémoire.

Sparganium erectum - fruit
Bur-reed (Sparganium erectum) is an easily identified plant in late summer and early fall because of its extremely distinctive ball-of-spikes fruit (pictured above). This genus of plants is relatively common in the area; I can recall three species off the top of my head that grow in this area. It's the closest genetic relative of the cattail, if I understand correctly.

I haven't been able to blog in the last few weeks because I've been ridiculously busy. Life has been extremely hectic. The good news is that I'm loving my new program and I have a research assistantship that's helping to pay the bills and keep me and E both in school. I'm struggling a bit with a number of things, but I've managed somehow to keep my head above water.

At least I have a couple of super-cool field laboratories this week!

Ebony Jewelwing - Calopteryx Maculata - Demoiselle

When we were climbing Mont Cayamant I saw a number of odonata I don't usually see at the lake where I am generally, which is interesting considering that they're within a bare 15km of each other. In any case, I spotted a female ebony jewelwing damselfly, Calopteryx maculata. She was fortunately not very shy at all and it was easy to photograph her quite extensively.

Female C. maculata
 This is a good shot that shows the creature pretty well, I think. I know it's a female because it has the white stigma (spot on the wing); males of this species don't have the white spot.

C. maculata face
 I like the fierce, toothy appearance of a damselfly face.

C. maculata eating its prey
In this photo you can see that she's eating a bug that she's caught. Cool-looking creature.

Water Smartweed - Persicaria Amphibia - Renouée Amphibie

I'm finding that there are far fewer easy guides to aquatic plants in the region. I was very lucky to stumble on the identification of this plant. I present: water smartweed (fr: renouée amphibie), Persicaria amphibia.

P. amphibia inflorescence

I found this to be quite a lovely flower, with very long ovoid leaves. The flower stalk rose out of the water about eight to twelve inches and the pink flower stalks were each growing off a single branch of the plant.

Sweat Bee - Augochlorella Aurata - Abeille

Je ne sais pas le nom de cette abeille en français; le nom anglais inclut plusieurs espèces. Je ne peux donc donner que le nom scientifique pour l'identifier. Ceci est Augochlorella aurata, une abeille semi-sociale. Elle qualifie comme une abeille solitaire; chaque reine fait tout le travail de son nid et n'a pas d'abeilles travailleurs. Elle est semi-sociale parce que les reines de l'espèce A. aurata s'assemblent parfois en groupes de nids où elles partagent le travail de la construction du nid, mais toutes les individus sont des reines et la collecte du pollène et du nectar est faite par chaque reine. Il n'y a pas d'évidence de communication entres adultes de l'espèce A. aurata.

A. aurata
This is one of the number of species referred to commonly as a sweat bee, apparently due to their attraction to the salt in human sweat. I hunkered down in the grass and photographed a number of bees visiting a particular stalk of goldenrod. I managed to capture a number of bees, including the particularly striking Augochlorella aurata. I also saw but was unable to photograph an Augochlora pura individual. I've always been reasonably observant but this was the first time I realized that there are not one, but two varieties of green bee in the area. I counted 15 different species of bee and wasp in 15 minutes of sitting by the goldenrod, which represents a truly stunning biodiversity. I was only able to get clear photographs of three of the 15 varieties (1/5), but I suppose I'll just have to go out again!

Yarrow - Achillea Millefolium - Herbe à Dinde

A. millefolium inflorescence
Cette plante est très commune dans la région. Elle est facile à identifier et préparée comme thé était utilisée part les aborigineaux pour réduire la fièvre et pour aider à dormir. Je met cette plante dans mes tisanes, mais elle a un goût très fort donc je conseille les gens de l'utiliser de manière restraint. Avant d'y goûter, on devrait s'assurer qu'on n'a pas de réaction négative à cette plante, auquelle il y a parfois des allergies. Je suggère qu'on frotte la plante délicatement sur la peau et attende plusieurs heures; si la peau réagit, ne pas ingester la plante. Il faut toujours faire attention en ingestant des plantes sauvages et je n'encourage à personne de consommer des plantes sauvages sans s'assurer de n'avoir aucune allergie dangereuse et d'avoir aucun doûte de l'identification de la plante.

L'herbe à dinde est utilisée pour traiter de divers conditions et maladies. Un petit dix minutes avec Google montre que le monde crois à toutes sortes de bénéfices à cette herbe. Je vous encourage à évaluer les prétentions avec caution; beaucoups de ces prétentions ne sont aucunement prouvés et il faut exercer son jugement pour évaluer l'évidence. Nous savons que l'herbe à dinde contient de l'acide salicylique, qui peut réduire la fièvre et réduire la douleur. Il faut se souvenir qu'il est très difficile de contrôller la dose d'une substance qui se retrouve dans une plante sauvage et que ceci n'est pas un bon substitut pour des médicaments à dose controllée.

A. millefolium lateral view
Yarrow (also called: arrowroot, bloodwort, nosebleed, soldier's woundwort, & many other names)  is a very common plant in this region. It's easy to identify and as a tea was used by aboriginal people to reduce fever and help with sleep. I put this plant in my herbal teas, but it tastes quite strong so I suggest that people use it only moderately in tea unless you want your tea to taste like nothing else. It can cause allergic reactions so I would suggest that you rub some on your skin and check back in a few hours to see if you have a reaction before ingesting it. Also, the usual disclaimer about not ingesting wild plants if you have dangerous allergies and never to ingest a plant you don't have an absolute positive identification of.

There are a lot of claims all over the internet about the various (semi-miraculous, to hear some tell it) properties of yarrow. I would recommend that these claims be judged on their merits and on the weight of the evidence. We know that yarrow does contain salicylic acid, so the fever reduction and pain relief properties are likely to be true. All other claims need to be similarly evaluated on their merits. It's important to remember that even when we know that a plant contains a compound with known medicinal properties, the wild plant will always be a worse form than the pill because of issues controlling dosage; yarrow tea is not an improvement over acetaminophen, it's a step down because dosage is not known (less effective and less safe;  if you have the pill, don't substitute the herb).

A. millefolium bottom view
I'm taking time at the lake to try to recuperate. I'm working away at a number of things. Saw a deer with two young this morning. I'm snuggling my grumpy old Molly cat, who seems old now in a way she didn't last year. Still, I suppose she had to start acting like an old cat sometime and I guess if she starts in her 20th summer I shouldn't complain. I have a sense of permeating loss, the feeling of summer fading away into autumn... It's a strange feeling to experience combined with the excitement of changing my program and pursuing what I really want out of life.

Water - Eau

I'm reminded of an Arrogant Worms song: Rocks and Trees. 'Cause in Canada, we have rocks and trees and water.

Here are some photos of the water.

Small falls

There are features like this all over the Canadian Shield. It's a common (beautiful) sight. These falls have no name, as waterfalls in around here only earn a name when they're quite big. Otherwise there'd be named falls everywhere. Maps would become impossible.

Bridal Veil Falls
This photo of Bridal Veil Falls was taken in August, when the water flow is close to its lowest. In spite of that there's plenty of flow. This photo only encompasses about half of the falls, as it wasn't possible to climb down to the bottom of the falls safely.

Turbulent creek

Shallow, turbulent water is another common and beautiful sight in this region. There are streams and creeks everywhere. I love the pebbled effect of the water as each small flat portion of the surface reflects a slightly different image from the bottom.


This is the creek where the turbulent water photo above was taken. It winds its way through the forest. The waterfalls above are both on this water system, as well.

Pink Lake colours

This is a photo of the intense colour of Pink Lake, the nature of which is explained on the web page I've just linked. Below is another photo showing the form of Pink Lake a little better.

Pink Lake

Canada is a beautiful country.

Le Parc de la Gatineau se retrouve sur la frontière du Quebec et de l'Ontario. C'est une région qui demeure sur le boucle Canadien, qui contient beaucoup de systèmes d'eau. C'est ici où j'ai grandi, entouré d'arbres et d'eau. C'est un paysage dangereux et difficile, où la saison d'agriculture est courte et les températures sont extrèmes, mais c'est aussi un paysage incomparablement beau.

Wood Sprite - Fée des Bois

So one of the things I found when wandering Gatineau Park was a stump which was deep, brilliant red. In some places it was the colour of blood and in others the colour of flames. I couldn't resist photographing it, of course.

Red stump
And when I got in close, I saw the shape shown below. It's things like this that make it easy to anthropomorphize plants or to imagine the existence of a sentient form of plant life.

Looks like a face
Of course, the human brain is particularly good at looking for faces (especially eyes) in things, so it's hardly surprising that gnarled patterns of grain in a piece of wood could end up looking like faces to us.

Moss - Mousse

Unfortunately, I can't identify the actual moss in these images (there aren't exactly a lot of field guides to moss identification). I've always found moss rather fascinating. I love the texture and appearance of mosses.

Moss gametophytes

 The second picture is my desktop background because I just love the texture. It's a fascinating-looking plant.

I've been very busy and stressed for a number of reasons in the last few weeks and I haven't been blogging much as a result. I still have tons of pictures to put up and things to say, I just needed to focus on the various crises that have laid themselves at my door.

The good news is, I've got everything sorted out for my change in program. I'm going into biology with a focus on ecology and agriculture. I have a qualifying year to do before entering a Master's program. I'm very pleased with my decision, in spite of the veritable avalanche of administrative crap I've been buried under getting everything sorted out. I've finally worked through all of it, save a last little bit to do next week which should take nothing more than showing up at my faculty to get registered in a course that's not part of my program.

I've been looking into field courses and I'm very eager to participate in a number. There are more field courses I want than time to take them all, but I suppose I'll just have to figure it all out.

There has been a death in the family and I won't be able to attend the funeral. I've been struggling with that a bit but I simply don't have the time to wallow; I don't have the breathing room to indulge in this, that's why I can't go to the funeral either. There are some extremely urgent matters I need to take care of.

I've finished my lab hours for the summer, so thankfully I should have a bit of a chance to rest now, if only briefly. I intend to take full advantage. I ease the stress with time in the woods; it works well.

Black-Eyed Susan - Rudbeckia hirta - Rudbeckie

The black-eyed susan (this one is: Rudbeckia hirta) is a very common and recognizable flower, which many find very showy and attractive.

R. hirta inflorescence
Black-eyed susans are a very distinctive class of flower, easy to spot and identify.

R. hirtaserotina inflorescence lateral view
The conical shape is quite evident in a lateral view.

Black-eyed susans are a good cut flower.

Today, I'm planning.

White Baneberry - Actaea Pachypoda - Actée à Gros Pédicelles

Cette plante est toxique à manger! Ne jamais consommer, s'assurer que les enfants ne consomment pas cette plante. La tige devient rouge et le fruit devient blancs avec le point noir au bout quand mûr.

This plant is toxic! Never eat this plant and make sure that children do not eat this plant. When ripe, the stalk turns red and the fruits turn white with a black point at the end.

A. pachypoda
White baneberry is a reasonably common plant in the region where I grew up. It is a strange-looking plant, all told. 

Unripe fruit of A. pachypoda
The fruit looks like it's watching you. As I understand it it is also called Doll's Eyes, a name I find quite appropriate, especially when the fruit has ripened and turned white.

Today I'm tired.

Shoya Long Eggplants

So I just had the most delicious eggplant I have ever eaten (yes, for breakfast; breakfast eggplant is awesome). I planted a number of varieties of eggplant in the garden this year, among them the shoya long eggplant, which came highly recommended for yield and flavour. Boy is it ever delivering on both counts! The plant I have is blooming still and also has about 40 developing eggplantlings on it. Yep. So this morning the first one was ready to be picked. I picked it, and cooked it up right away.

And it was the most phenomenal eggplant experience I have ever had. It was so silky, and so richly flavoured, that I couldn't quite believe at first that I hadn't accidentally ingested a hallucinogenic eggplant. To be clear, I love eggplant. I eat it at least once a week and spend a lot of my cooking endeavours trying new ways to eat eggplant. So when I say that this eggplant was the best eggplant I've ever had, I mean it was practically a transcendental experience.

I may be exaggerating slightly.

So, without further ado, here's the eggplant, and instructions for how to cook it the way I did this morning.

Shoya long eggplant
 So I wanted to cook it in a way that would bring out the flavour of the eggplant, since I'd never had this eggplant before and wanted to know exactly what it tastes like. As a consequence, the following recipe is very simple and takes about 5-10 minutes. Also, it's in my cooking style, which means I measure exactly nothing.

-Olive oil (enough to coat your pan lightly)
-Garlic (to taste)
-Basil (to taste)
-Oregano (to taste)
-Balsamic vinegar (to taste)
-Salt (to taste)

-Cut eggplant into rounds about 1/4" thick
-Mince garlic and let air for a few minutes
-Chop basil & oregano up finely (about 1/10th as much oregano as basil)
-Heat frying pan with a dollop of olive oil; hot pan, for sautéeing
-Toss eggplant rounds into frying pan & cover
-When the rounds start to soften, toss them around a bit
-Throw on a dash of balsamic vinegar and stir it through the eggplant (be sparing at first! that stuff tastes strong and you don't want to overpower the delicious, delicious eggplant flavour)
-Pitch in the herbs and a dash of water (no more than a few Tbsp of water, just enough to deglaze the balsamic off the bottom of the pan so it can be redistributed onto the eggplant)
-Once the eggplant is soft, remove cover, stir, and cook until the water is evaporated from the pan
-Salt to taste

End result:
The most delicious eggplant I've ever eaten
Pour les francophones:

Je vais juste remarquer que je ne mesure rien en préparant mes plâts (à l'exception de la cuisson au four), préférant plutôt de me fier au goût et à la scenteur pour ajuster les quantités. Par conséquence, je ne peux pas vous fournir des mesures de quantité dans mes recettes. Mes excuses.

-Huile d'olive (assez pour couvrir le fond de la poêle)
-Ail (à son goût)
-Basilic (à son goût)
-Origan (à son goût)
-Vinaigre balsamique (à son goût)
-Sel (à son goût)

-Couper les aubergines en rondelles d'environ 1/4'' de large
-Hacher l'ail et laisser à l'air pour quelques minutes
-Hacher le basilic et l'origan (l'origan devrait représenter environ 1/10ième de la quantité du basilic)
-Rechauffer la poêle avec l'huile d'olive dedans (assez chaud pour sauter)
-Y jetter les aubergines, remuer, et couvrir
-Quand l'aubergine commence à amollir, remuer encore
-Ajouter un peu de vinaigre balsamique (faire attention! Ce vinaigre goûte très fort et on ne veut pas déguiser le goût délicieux de l'aubergine)
-Ajouter le basilic, l'origan, et l'ail avec un peu d'eau (pas plus que quelques cuillères à table, juste asser pour déglacer le vinaigre)
-Quand l'aubergine est devenue molle, découvrir, remuer, et laisser cuire jusqu'à temps que l'eau a toute évaporie
-Ajouter du sel à son goût

Bon appétit! Le résultat final est présenté ci-haut.

Leafcutter bee - Megachile - Mégachile

This morning has been quite exciting for bees. We've confirmed that there are at least two bees in the B. impatiens hive (no photographs yet), and I've discovered that my bee solitary bee houses are being put to use.

I can confirm only that it's a leafcutter bee (fr: mégachile), genus Megachile. Unfortunately, I'm not able to pinpoint the exact species any more precisely, as I'm not a specialist in the leafcutter bees. Nevertheless, I can provide a photograph of a nest cell, and of the leafcutter bee. Enjoy!

Occupied Megachile nest cell, with distinctive cut leaves

As I understand it leafcutter bees favour the leaves from roses or lilacs for their nest cells. I think that the leaves here must have come from the lilac tree, which is within six feet of this nest cell (there are no roses nearby).

Megachile - leafcutter bee on mustard flower
I was very pleased to get such a clear photo of this bee. She's got the distinctive colour and stripe pattern of a leafcutter bee, as well as the distinctive outward resting position of the wings. Unfortunately I don't know encough about leafcutter bees to be able to identify what species she is. I don't know if this is the same one who built the nest cell photographed above, but I do know it's the same genus of bee, at least.

It's a beautiful day to be out in the garden.

White Pine - Pinus Strobus - Pin Blanc

While I was out for a stroll in the early morning (went looking for chanterelle mushrooms with my father), I realized I hadn't put any tree photographs on this blog. Want to remedy this. Below is a photograph of the branch tip of a white pine (fr: pin blanc), pinus strobus. It's a very common species in Quebec, and in the area where I took this photograph it is usually one of the largest; conditions are quite rough and most trees grow very slowly (the ironwood is usually around 50 years old at a 4" diametre).

The cones are just barely starting to form.

P. strobus
As I was taking my early morning meandering, I also saw a common mallard (fr: mallard), anas platyrhynchos. There was a mother and one duckling; likely she started with more and the rest have been eaten or died of other causes. I particularly like the look of the water in this photograph, with the patterns of refraction along the wave peaks. Also, I just think the fuzzy duckling is cute.

Immature a. platyrhynchos
Today I'm struggling.

Wood Frog - Rana Sylvatica - Grenouille des Bois

So this is another one spotted at Mont Cayamant. There were some stray puddles along the path (vernal pools), and they were filled to the brim with tiny little frogs and tadpoles. In the photo below, notice that the frog is sitting on a leaf. That's a pretty normal maple leaf, about four inches across or a little less. So the frog is teeny tiny. Note that wood frogs habitually breed in vernal pools, so this was by no means an unexpected finding. What I loved was their sheer number. Just as well, because they wouldn't stay still for photos! I got my feet very wet photographing this little guy.

Immature R. sylvatica
Though the light conditions were rather poor for photographing into the water, I managed to get a shot of a tadpole in its late stages of development:

R. sylvatica tadpole
It was a fun hike.

Squawroot - Conopholis Americana - Conopholis d'Amérique

Squawroot is an achlorophyllous (non-photosynthesizing) plant which grows as a parasite on the roots of oak and beech. We encountered several of these in our hike up Mont Cayamant the other day. I think it's a rather strange-looking plant. Visible in the picture below is the above-ground infructescence; at this time of the season, the flowers have been replaced with seed pods.

C. americana infructescence
Today I'm feeling impatient.

Twistedstalk - Streptopus amplexifolius - Sceau-de-Salomon

This one is comestible, but because it resembles a lot of toxic plants in the region, don't eat this plant unless you're absolutely positive about identification (somebody who knows for certain shows you, rather than just comparing to a picture). Large quantities of the fruit can give diarrhea as well, so be light on eating them once you do have a positive identification.

S. amplexifolius from below
Nous étions allés à Mont Cayamant hier. Sur la piste il y avait beaucoup à voir; j'ai pris un tas de photos. C'est un très bel endroit et du belvédère le paysage est extrèmement beau. Ne pas aller sans de bonnes chaussures ou bottes! Le chemin est ménagé, mais s'agit quand même d'une piste dans une forêt. Faire attention aux falaises.

Mallard - Anas Platyrhynchos

Of course no trip to a Canadian waterway is complete without a sighting of the mallard duck, the ubiquitous water bird. This particular group was swimming through a patch of water which was particularly interesting-looking from my angle, so I ended up being able to capture a beautiful effect in the water as well as the ducks themselves. Enjoy.

A. platyrhynchos juveniles
Today, I'm getting things in order.

Milkweed - Asclepias Syriaca - Herbe à la Ouate

Here's a common, easily recognized one: common milkweed (fr: herbe à la ouate), Asclepias syriaca. It's very attractive to butterflies and as such is wonderful to have around, but it's important to keep it out of pastures as it is toxic to a number of grazing animals.

A. syriaca on the shore
There's a hint of red clover and some grasses and hawkweed in the bottom of this image, too, but the focus is on the milkweed. Quite a dramatic plant. I like the effect of the milkweed against the backdrop of the rapids.

Ants collecting nectar from the flowers of a. syriaca
Not only does this flower appeal to bees, it also appeals to ants. I hardly ever see them blooming around here without ants crawling around on them seeking nectar. I like the umbrel shape of the milkweed inflorescence.

A. syriaca inflorescence
I love how thick the flower is. The petals are proportionately extremely thick for their size, giving this flower a stiff, chunky appearance that I find really cool and unusual in a flower. It's quite a dramatic flower even up close. There's a drop of dew visible between the two nearest petals of the flower in the centre here.

St John's Wort - Hypericum Perforatum - Millepertuis Perforé

St John's wort, hypericum perforatum (fr: millepertuis perforé) is another introduced species which now flourishes at the lake. It is a fairly well-known herbal antidepressant. It's worth noting here that herbal antidepressant just means it contains neurotransmitter reuptake inhibitors and it's an herb, not that plants are magical and better than proper pharmaceuticals. Dosage is inexact with herbs (as opposed to pill-form SSRIs, which have dosage controlled) so I wouldn't recommend that everybody go running out to make St John's wort tinctures. At least in Canada, measured doses of St John's wort extract are available over the counter anyway, so if you want to try it go try that. Disclaimer: talk to your doctor, St John's wort interacts with a number of common medications (eg oral contraceptives) in ways that can be extremely bad for you. Self-medication is dangerous, talk to your doctor or pharmacist about this option.

H. perforatum inflorescence
This flower isn't always easy to spot; it tends to grow close to goldenrod at the lake, and the two have a very similar colour while goldenrod is generally taller, making it a tough spot at the lake. The plant itself is very easy to identify, however; I've never seen anything else that looks like it growing at the lake, so if it looks like this it's probably St John's wort.

H. perforatum inflorescence up close
I love the form of the filaments & anthers on this flower. It's like a koosh ball cut in half. It's a very wibbly (I swear that's a word) sort of flower. Pretty and delicate, with the perfect rich golden colour that I'm glad has come out here very well. It's not a very large flower, at least at the lake; usually 1-2 cm across.

I'm making big changes to my life right now. My anthem right now is Chris Hadfield's rendition of Space Oddity because to me this is an incredible symbol of the triumph of the human spirit and human innovation. Decades ago, this song was sung looking up at the stars from Earth; now Chris Hadfield has sung it back to Earth from the stars. That's so incredible I have a hard time believing it sometimes. Also, I've never gotten over the childhood hero-worship I had for astronauts. Astronauts are incredible people; if my eyes didn't suck I would have tried to become one myself (but you need to be not totally useless in an emergency if you can't find your glasses, and my eyes suck without some form of intervention; I discovered the hard truth at 12 years old and I still wish I were eligible for laser eye surgery). Anyway, this song makes me think of just how incredible humanity can be. Steels the guts for hard work.

Snapper - Chelydra Serpentina - Tortue Serpentine

Sur la rivière où j'étais durant la fin de semaine au chalet de mon amie, il y avait une crique où se trouvaient de diverses insectes et animaux. En entrant, j'ai surpris un héron qui s'est envolé avant que je puisse sortir ma camera, et un castor qui a frappé l'eau avec sa queue avant de disparaître sous la surface. J'ai vu aussi une tortue serpentine.

La tortue serpentine est très commune, mais le monde a souvent des idées incorrectes par rapport aux habitudes de cette espèce et mon amie me disait que, il y a 50 ans, le monde ont fait l'éffort pour éradiquer les tortues serpentines dans la rivière, étant peur de se faire mordre en nageant. La tortue serpentine, chelydra serpentina, est extrèmement non-agressive dans l'eau et même sur terre où elle est plus vulnérable n'attaquera pas sans provocation. En tout cas, cette espèce est vieille, ayant pré-éxisté les dinosaurs dans la forme que  nous reconnaissons aujourd'hui. Pour moi, rencontrer une tortue serpentine, particulièrement une grosse, c'est comme recontrer un dinosaur. Ce sont des créatures fascinantes. J'ai été chanceuse durant la fin de semaine; cette tortue voulait prendre un petit peut de soleil et a donc sorti un petit peut de la boue, juste assez que j'ai pu la voir.

Celle là est grosse pour son espèce mais pas la plus grosse que j'ai jamais vue (cela est une autre histoire, une que je ne compte qu'au monde qui adore aussi la nature). J'estime 12-15 pousses dans la carapace, qui représente une tortue dans la cinquantaine ou plus. Ci-dessous est une photo de la tortue, qui était bien cachée dans la boue.

C. serpentina
Above is a photo I took of a snapper (common snapping turtle), chelydra serpentina. This is a very common acquatic animal in North America. Unfortunately, people have some strange ideas about snappers which make them more nervous and aggressive about snappers than need be. Snappers are very peaceable creatures and shy in the water, preferring to flee than to confront when met with humans. On land, they are only aggressive if provoked -- and that's because they have no alternatives; they can't run and this variety of turtle can't hide in its shell for safety. If you see one on land it's probably a female looking for a place to lay her eggs. Leave her be and she'll leave you be.

This one was very well-hidden in the silt at the bottom, taking a bit of sun but trying to be more or less invisible. It's a reasonably large one for its species; I estimate 12-15 inches in the shell, which is quite respectable and means it's probably about 50 years old or a bit older. The inlet where I spotted this turtle is full of silt, where my friend says the snappers like to hibernate in the winter, buried in the silt. And no wonder; I tested the depth with my paddle; my paddle sank all the way down without touching the bottom, so all I can say for certain is that the silt is deeper than 5 feet. Plenty of room for turtles to bury themselves in! Mind you, it does mean that it's a good thing I didn't hop out of the kayak in this seemingly shallow water; the moral of the story is to check your surface before hopping out of your boat, in case the bottom isn't what it seems.

This is the type of sighting that happens by being quiet; take a kayak or a canoe, no motors! Paddleboats are pretty noisy, too. This turtle would've been gone long before I arrived if I'd been in a noisy boat.

Today, I'm making changes.

Dragonflies - Odonata - Libellules

So when I was at my friend's cottage, I went out kayaking on the river. There was a small inlet not far downstream of us, where I found an unbelievable variety of dragonflies, many of which I had never seen before. The two most abundant types were a red one I have finally been able to identify as the calico pennant, Celithemis elisa.  The second is a black one with ice-blue markings, which I believe is the chalk-fronted corporal, Ladona julia. There were also quite a lot of monstrously huge dragonflies with ultra blue abdomens and dark green thoraxes which I didn't get a chance to photograph; they never seemed to land anywhere. I will say tentatively that they were probably common green darner dragonflies.

These dragonflies were incredibly difficult to photograph but I'm glad I succeeded in getting even these few shots.

I found this particular dragonfly to be a stunningly beautiful creature. I like this shot a great deal because it shows just how vibrantly red it is.

My kayak was unfortunately drifting, and you can see from the shadows of my hands that I was already reaching a point where I could simply not reach with my right hand anymore when I took this shot. I was so disappointed to see that I had clipped the wings on one side in this photo, which is otherwise perfect. I suppose I'll just have to try again sometime. At least in this photo the wing patterns are very clear. Aside from the lower wing near the thorax, the spots are not quite red, looking more muted and brownish to me.

I think at this moment I really must give my thanks to the folks over at Discover Life, who regularly make it possible for me to identify fauna that I wouldn't be able to without their excellent searching tool. Super cool resource, very usable. It's my go-to resource for identifying interesting insects.
