Convergent diversity and trait composition in temporary streams and ponds
Hydrology is the main environmental filter in aquatic ecosystems and may result in shared tolerances and functional traits among species in disparate ecosystems. We analyzed the associations between taxonomic and functional facets of diversity within aquatic ecosystems (ponds vs. streams) across a hydroperiod gradient (1–365 d) to untangle the hydrologic drivers of aquatic invertebrate diversit...
متن کاملTrait anxiety, trait depression, worry, and memory.
A study is reported which investigated the proposal that high trait anxiety is associated with a memory bias for worry themes. Forty-five participants were categorised as being high or low trait anxious on the basis of scores on the (Spielberger et al., 1983) (Manual for the State-Trait Anxiety Inventory (Form Y) (1983)). The participants were requested to rate a number of worry and non-worry s...
متن کاملStudies on Fletcher trait and Fitzgerald trait
The way by which contact of blood with foreign surface accelerates clotting has been elucidated from the discovery of four rare disorders of blood coagulation; Hageman trait, plasma thromboplastin antecedent (PTA) deficiency, Fletcher trait, and Fitzgerald trait. Interestingly, it was unexpectedly found that Fletcher factor is plasma prekallikrein and Fitzgerald factor is high-molecular-weight ...
متن کاملTrait-like vulnerability to total and partial sleep loss.
OBJECTIVE To determine the extent to which individual differences in vulnerability to total sleep deprivation also reflect individual differences in vulnerability to multiple nights of sleep restriction. DESIGN Two sleep loss conditions (order counterbalanced) separated by 2 to 4 weeks: (a) total sleep deprivation (TSD) of 2 nights (63 h continuous wakefulness); (b) sleep restriction (SR) of ...
متن کاملTrait-Dependent Extinction Leads to Greater Expected Biodiversity Loss
We use a classical combinatorial inequality to establish a Markov inequality for multivariate binary Markov processes on trees. We then apply this result, alongside with the FKG inequality, to compare the expected loss of biodiversity under two models of species extinction. One of these models is the generalized version of an earlier model in which extinction is influenced by some trait that ca...
