The effect of sheep grazing on alpine plant communities, species and populations: what is the importance of plant life histories?

Grazing is an important factor for plant dynamics, but it has proved difficult to generalise about grazing impact, partly because of a lack of a good mechanistic framework linking the grazing impacts on certain life stages to the dynamics of the populatio ns. A functional classification of specie...

Stress and neurogenesis in rainbow trout

It is currently agreed that new neurons are added to continually growing structures and replace old and dying brain cells in adults of all major vertebrate taxa, a process known as neurogenesis. These structural processes may be highly important for behav iour, mood, and cognition in both animals...
