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 ...

Effects of Prey-Mediated Sublethal Exposure to Imidacloprid and Nitenpyram on the Fitness and Predation Capacity in Chrysopa pallens

Insects
Chrysopa pallens Stephens (Neuroptera: Chrysopidae) is a key predatory species in cotton agroecosystems. This study investigated the prey-mediated sublethal effects of imidacloprid and nitenpyram at low concentrations (LC20), on C.

Predatory Behavior of the Basilica Spider, Mecynogea Lemniscata (Araneae, Araneidae)

Psyche: A Journal of Entomology, 1992
Females of Mecynogea lemniscata (Walckenaer) are generalist predators. Sixteen behavioral acts were described for M. lemniscata preying on house flies, carpenter ants, and Asiatic oak weevils in the field and laboratory.

Extent, characteristics and policy applications of Key Biodiversity Areas

Biological Reviews, EarlyView.
ABSTRACT A global standard for the identification of Key Biodiversity Areas (KBAs) was published 10 years ago to provide a unified set of criteria for identifying ‘sites of significance for the global persistence of biodiversity’. We review the initiative's origins, the KBA identification process, characteristics of the current network, threats, policy

Cell rupture in Arcellinida through the lens of evolution

Acta Protozoologica
The majority of predatory protists are size-limited. Arcellinida (Amoebozoa) exhibit the remarkable ability to prey upon larger rganisms.

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

Biological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Amur tiger urine enhances the foraging behavior of three major small-bodied mesopredator species in northeastern China

Ecological Processes
Background Apex predators exert dual effects on mesopredators, including both suppression through lethal encounters and fear, as well as facilitation through providing food via prey remains.

Exploring the evolution of a trade-off between vigilance and foraging in group-living organisms

, 2014
Despite the fact that grouping behavior has been actively studied for over a century, the relative importance of the numerous proposed fitness benefits of grouping remain unclear.

PREDATORY BEHAVIOR OF TETRAGNATHA PRAEDONIA (ARANEAE: TETRAGNATHIDAE)

Acta Arachnologica, 1987
The predatory behavior of Tetragnatha praedonia was studied. The prey consisted of mainly Diptera, especially midge flies, smaller than 3mm in body length. When capturing small prey, this species applied mainly “Seize-Pull out” strategy to them; that is, it plucked the web to locate the prey, ran and seized it in the jaws, pulled it out of the web ...

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
