Hippocampal neuroplasticity induced by early-life stress: functional and molecular aspects. [PDF]

open access: yes, 2006
Whereas genetic factors contribute crucially to brain function, early-life events, including stress, exert long-lasting influence on neuronal function. Here, we focus on the hippocampus as the target of these early-life events because of its crucial role

Arthropod conservation in roadside verges: Unmown refuges outperform mowing equipment changes

open access: yesInsect Conservation and Diversity, EarlyView.
While roadside verges might have potential as connecting corridors for grassland habitats and their inhabitants, roadside mowing negatively impacts grassland arthropod densities. In contrast to unmown refuges, all mowing techniques harmed grassland arthropods, with no significant differences between mowing equipment.
