Abstract:
... The ability to successfully cope with stress is known as 'resilience', and resilient individuals are less prone to develop psychopathologies. Understanding the neurobiological mechanisms of resilience may be instrumental to improve current therapies and benefit high-risk subjects. This review summarizes the complex interplay that exists between physiological and pathological responses to stressful ...

Abstract:
... Inferring functional components of behavioral sequences is a crucial but challenging task. A systematic comparison of their temporal structure is a good starting point, based on the postulate that more functional traits are less structurally variable. We studied stone handling behavior (SH) in Balinese long-tailed macaques, a versatile form of stone-directed play. We tested the hypothesis that sto ...

A. arenosa occurs naturally in both diploid (2C) and tetraploid (4C) form, in contrast to A. halleri in which only diploid forms were found. Moreover, A. arenosa similarly to A. halleri often occupies heavy metal (HM) contaminated sites. Nevertheless, knowledge about the ec ...

Abstract:
... The upper elevational range limit of tree species (including treeline and non-treeline species) is generally considered to result from either carbon limitation or sink limitation. Some evidence also suggests that tree line might reflect preferential carbon allocation to NSC storage at the expense of growth. How might the importance of these potential mechanisms be determined? We used an elevationa ...

Plants substantially vary in their physiological response to Se. The amount of Se in edible plants is genetically controlled. Its availability can be determined by measuring its phytoavailability in soil. The low concentration of Se in p ...
