Social context alters spatial memory performance in free-living male prairie voles [PDF]

Royal Society Open Science, 2019
Spatial memory is crucial for mating success because it enables males to locate potential mates and potential competitors in space. Intraspecific competition and its varying intensity under certain conditions are potentially important for shaping spatial

The influence of rivers on seabird foraging ecology

Biological Reviews, EarlyView.
ABSTRACT Rivers act as vital arteries to the world's oceans, delivering fresh water and nutrients that sustain marine ecosystems. Globally, river flow increasingly is being altered by climate change and anthropogenic pressures; yet the significance of rivers to predatory marine species, such as seabirds, and the extent to which river‐related changes ...

Fitness of crop-wild hybrid sunflower under competitive conditions: implications for crop-to-wild introgression.

PLoS ONE, 2014
Understanding the likelihood and extent of introgression of novel alleles in hybrid zones requires comparison of lifetime fitness of parents and hybrid progeny.

Competitive Interactions Among <i>Populus euphratica</i> Seedlings Intensify Under Drought and Salt Stresses. [PDF]

Plants (Basel)
Plant interactions and their responses to stress environments are important ecological processes for ecosystem stability and biodiversity formation, but how plant intraspecific relationships respond to environmental stresses remains to be studied in ...

Individualised niches: an integrative conceptual framework across behaviour, ecology, and evolution

Biological Reviews, EarlyView.
ABSTRACT Individuals differ. While seemingly trivial, this insight has nevertheless led to paradigm shifts, as three key fields of organismal biology have seen marked changes in key concepts over the past few decades. In animal behaviour, it has become increasingly recognised that behavioural differences among individuals can be stable over time and ...

A roadmap to key traits of invasive Drosophilidae

Biological Reviews, EarlyView.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.

Classifying avian drinking behaviour: ecological insights and implications in a changing world

Biological Reviews, EarlyView.
ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns
