Climate Change and invasibility of the Antarctic benthos [PDF]
Benthic communities living in shallow-shelf habitats in Antarctica (<100-m depth) are archaic in their structure and function. Modern predators, including fast-moving, durophagous (skeleton-crushing) bony fish, sharks, and crabs, are rare or absent ...

Predators avoiding predation [PDF]
The notion of stealthy predation often invokes images of a predator hiding and waiting to ambush its unsuspecting prey. In this issue of PNAS, Manicom et al. (1) offer an alternative reason why predators hide that involves an important tradeoff between capturing prey and seeking refuge to avoid their own demise from other predator species.

The antipredator benefits of postural camouflage in peppered moth caterpillars
Camouflage is the most common form of antipredator defense, and is a textbook example of natural selection. How animals’ appearances prevent detection or recognition is well studied, but the role of prey behavior has received much less attention. Here we

In the wild, mice have developed survival strategies to detect volatile cues that warn them of potential danger. Specific olfactory neurons found in the Grueneberg ganglion olfactory subsystem can detect alarm pheromones emitted by stressed conspecifics,

Sticky Exudates on the Inflorescences of \u3ci\u3eCirsium Discolor\u3c/i\u3e (Asteraceae) and \u3ci\u3ePenstemon Digitalis\u3c/i\u3e (Scrophulariaceae) as Possible Defense Against Seed Predators [PDF]
From 1982 through 1987, I investigated whether sticky exudates released by Cirsium discolor and Penstemon digitalis in their inflorescences provide defense against seed predators. I tested two hypotheses: 1: Exudates directly deter seed predators, and 2:

Pest species diversity enhances control of spider mites and whiteflies by a generalist phytoseiid predator [PDF]
To test the hypothesis that pest species diversity enhances biological pest control with generalist predators, we studied the dynamics of three major pest species on greenhouse cucumber: Western flower thrips, Frankliniella occidentalis (Pergande ...

Geometric factors influencing the diet of vertebrate predators in marine and terrestrial environments [PDF]
Predator–prey relationships are vital to ecosystem function and there is a need for greater predictive understanding of these interactions. We develop a geometric foraging model predicting minimum prey size scaling in marine and terrestrial vertebrate ...

Population dynamics of aphid and coexisting predators in tomato agroecosystem
Aphids generally attack vegetative plant parts, preferably leaves, and devitalize the plant by sucking the cell sap. Thorough knowledge of pest-predator ecology and their interaction is requisite to initiate timely pest management strategies ...
