Mitosis

Quickly, a very nice mitosis from a lily, first, and then below in an animal cell… These are nice (dare I say cute?) films found on UTB…

Mitose

Rapidement, une jolie mitose chez le Lys tout d’abord, puis en dessous chez une cellule animale en culture… Un adorable petit film déniché sur UTB…

Blogger BioBlitz 2007 (3)

Here is first a list of plant species that I formally identified during the blitz week (there are a few that I didn’t, for I lack time, a good field guide, and a better knowledge of the focal plant). Definitely no trees in the list: too big, no leaves yet (or too young leaves), and I [...]

Moving to the field!

(some French below)
Hi folks, it’s spring and plants will begin flowering. I have to go to the field for the next two months. I don’t know as to how it will modify this blog’s life yet, but I surely will enjoy a more wilder life and may even have done nice experiments when I’ll come [...]

Blogger BioBlitz 2007 (2)

Here’s one of the species I have not identified yet, that I’ve met last sunday during my second BioBlitz… If anybody can help with identification of this snake (below), it would helpme fill my Blitz datasheet… :-)

Voici une des bêtes que nous avons rencontré dimanche dernier en nous promenant dans la forêt.
Je raconterai la petite [...]

What’s wrong? Cherchez l’erreur… :-)

Blogger BioBlitz 2007

(Some French below the fold)
I signed to Blogger BioBlitz 2007, a blogging naturalist event occuring… now, err this week (from 21-st to 25-th of April). The principle is quite simple: proving systematics is a lot of fun (i.e. naturalizing, botanizing, insecting err bugging, dissecting, flowering, birding, fishing, walking, rooting, making a lot of nice pictures, etc).Furthermore, to the limits [...]

If you self, you’d better do it generously!

Selfing, or self fertilization, is common in hermaphroditic plants that are self-compatible (i. e. without physiological mechanism to impede fertilization between its own gametes once they are brought together –the point here is that plants can be artificially selfed when one wants to know about the species self-compatibility status).

Si tu t’autofécondes, autant le faire généreusement!

L’autofécondation est un phénomène relativement courant chez les plantes hermaphrodites qui sont auto-compatibles (càd. sans mécanisme physiologique pour empêcher la fécondation de ses propres gamètes quand ils sont mis ensembles –le point ici est que les plantes peuvent être artificiellement autofécondées si quelqu’un souhaite savoir le statut de compatibilité de l’espèce en question).

Science or France?

Just a few comments on the whole bunch of French relationship with science stuff just published in Nature this week. I still wonder why France would deserve so much attention, beside its obviously painfully long divorce between science and politics, even if candidates now play a charming prince game [1, 2, 3].
