The longleaf pine (LLP) savanna ecosystem once covered ~ 92 million acres of the Southeast USA, but due to anthropogenic activities such as logging and fire suppression, only 3% of its once widespread historic range remains. While many rest...

We investigated the rapid initial response to wounding damage generated by straight cuts to the leaf lamina and midrib transversal cuts in mature aspen (Populus tremula) leaves that can occur upon herbivore feeding. Wound-induced volatile e...
Heat tolerance of early developmental stages of glacier foreland species in the growth chamber and in the field [0.03%]

In glacier forelands, seeds readily germinate, however, a high proportion of seedlings die shortly after their appearance. We hypothesized that besides drought, frost and missing safe sites, heat on the ground surface could be one of the ma...
Climate and taxonomy underlie different elemental concentrations and stoichiometries of forest species: the optimum "biogeochemical niche" [0.03%]
气候和分类学决定了森林物种中不同的元素浓度和计量比：最佳的“生物地球化学生态位”

J Sardans
We previously hypothesised the existence of a "biogeochemical niche" occupied by each plant species. Different species should have a specific elemental composition, stoichiometry and allocation as a consequence of their particular metabolis...
