How Much Olive Oil On A Dogs Food A Day
how the forest is Guyanese?
First, very varied, so I limit myself to what I have traveled, that of Paracou.
First, it is rather curious: if I had not kept a souvenir of my day pretty cool plane, I could forget that I changed continent. Exit
layouts hell Green, or Emerald Cathedral: the great green Guyanese remains a beast after all forest trees, some vines, saplings, shrubs, grass, a bit high ...
Ah, is ... a palm tree. And then yet another, which is really 15 meters high, and whose palms are more than twice my size.
And then what looked like tall grass now takes the form of a creeper ... and that one of She notched the forearm while I had barely touched
... Am I dreaming? I thought I saw a dead leaf to escape from under my feet! After a minute of hunting, that's cornered, and it turns out it's a toad!
And these vines that hang there, straight, vertical, here's one that does not touch the ground: they are the roots of epiphytes, plants that grow attached to trees, top of the canopy ...
And here is believed to cross a big wooden partition, it is the foothills of kimboto, a huge tree.

How Much Is A Canine Tooth For My Dog
my tutor, and a kimboto (another tree buttresses), quite impressive. That said, I cross larger.
A Passion.
Paracou one day Rain.
Idem.
epiphytes.
The pink spots is a Couratari in bloom. During flowering, the whole crown turns pink. Sorry for the quality: it is not easy to photograph a tree canopy.

Canker Translation Shakespeare
So it was two months I put up my device. 2 months
Cad forest almost daily.
What is my job?
In short, it is to see how different species of trees (initially 18, now 9) adapted to an environment light, ie how a change of lighting environment, or a particular light environment influences its growth, its architecture, some properties of its leaves.
For that, I spent two months traveling Paracou forest (mainly primary forest) to look for young trees in a particular light (on a scale of 1 to 4, 1 for an individual workplace closed, 2 for an individual receiving the light side, 3 for an individual receiving direct sunlight, and 4 for an individual in bright, direct and lateral).
This involves individuals in search of windfalls; where trees have fallen a year ago or more, which is not obvious.
Once these individuals found, marked with GPS and / or against a tree when there were numbered, he had to be measured (total height, height of first branch or leaf, crown size, number of branches , leaves, branch level ...), mark the main axis, and three branches at the apex (terminal bud) and count the leaves before and after the mark to be able to track mortality Coy and leaves. Once duly
"equipped", labeled and Co., the tree looks like this:
soon I will take advantage to introduce you to some of these species. So I
currently located and measured 600. I still ironing see forty of them to redo the missing steps, or GPS points in the next few days.
Then, I will characterize the light environment of these young trees. For that, I'll use a camera equipped with a hemispherical lens to photograph the sky. Then, a program locates the portions of sky in the picture, and calculates the amount of light radiation received from the whole point of taking the photo.
This kind of picture unfortunately can not be done in the absence of the sun in the sky, ie just before sunrise or just after sunset.
The third session will aim to field samples of leaves on several units of growth of each individual to study the evolution over time of certain parameters (nitrogen content, leaf thickness, delta C13 etc. ...) after the opening, and their variation with the light environment. These factors measured will include a proxy for studying the efficiency of water use per leaf (ratio transpiration / photosynthesis) photosynthesis ... etc.

My first field session is over, I'll have more time to get my blog updated.
I have accumulated a small bunch of photos to upload, and this time I'll make the effort to write some articles.
