Intraspecific diversity can have as strong an effect on communities and ecosystems as more well‐studied effects of species diversity. Intraspecific variation in prey body size may have particularly strong effects on populations by influencing the outcome

Analysis of temperature adaptability of Eocanthecona furcellata (Wolff) (Hemiptera: Pentatomidae) based on age-stage, two-sex life table and predatory functional response. [PDF]
Eocanthecona furcellata (Wolff) (Hemiptera: Pentatomidae) is a key natural predator of agricultural and forestry pests. In nature, temperature affects the growth, development and predation ability of predators.

Convergent iridescence and divergent chemical signals in sympatric sister-species of Amazonian butterflies [PDF]
The evolution of traits in closely-related species living in sympatry strongly depends on both shared selective pressures and reproductive interference.

Evaluation of the Effect of Ecological Factors on Cannibalism in Pelophylax bedriagae (Pallas, 1771) (Amphibia: Anura) [PDF]
Marsh frog, Pelophylax bedriagae tadpoles habituate in temporary wetlands where intraspecific aggression has been observed. In this study, we examined the independent and interactive effects of predator cues, water level and density on head width size ...

Predation is a key driver of phenotypic diversification with prey having evolved sets of correlated anti-predator traits. Changes in anti-predator traits can be studied on an evolutionary as well as on a developmental timescale.

The frequency of body scarring in Caspian Whip Snakes (Dolichophis caspius Gmelin, 1789) in south-western Hungary [PDF]
Animals can suffer injuries due to diseases, intraspecific aggression and, most of all, predation events. We present field data to provide numerical information about the injuries found in the largest Caspian Whip Snake (Dolichophis caspius) population ...

Background Host-parasite interactions represent complex co-evolving systems in which genetic and associated phenotypic variation within a species can significantly affect selective pressures on traits, such as host immunity, in the other.

Is the spider a good biological control agent for Plutella xylostella (Lepidoptera: Plutellidae)?
Spiders, as predators of insects and other invertebrates, are an important part of the natural enemies, and they are recognized as an important biological control agent.
