Rationale and objective The aim of this study was to investigate the possible facilitating effect of the partial NMDA receptor agonist D-cycloserine (DCS) on memory consolidation of conditioned sexual responses and to examine the capability of DCS to reduce context-specificity of learning. Methods In a randomized placebo-controlled double-blind trial, 50 healthy females were exposed to a differential conditioning procedure. Tw...

Tropical forests play a major role in the carbon cycle of the terrestrial biosphere. Recent field studies have provided detailed descriptions of the carbon cycle of mature tropical forests, but logged or secondary forests have received much less attention. Here, we report the first measures of total net primary productivity ( NPP ) and its allocation along a disturbance gradient from old‐growth forests to moderately and heavil...

Aim Disentangling the effects of climate and historical factors on biodiversity distribution remains a challenge for biogeographers. Here, we provide an analytical framework to discriminate the contributions of contemporary climate and the biogeographical history of taxa to the geographical distributions of phylogenetic lineages. Furthermore, we evaluate the constraint that the biogeographical history of clades exerts on the a...

Temporal variation in survival, fecundity, and dispersal rates is associated with density‐dependent and density‐independent processes. Stable natural populations are expected to be regulated by density‐dependent factors. However, detecting this by investigating natural variation in density is difficult because density‐dependent and independent factors affecting population dynamics may covary. Therefore, experiments are needed...
