Does predation pressure drive heronry birds to nest in the urban landscape?

Journal of Asia-Pacific Biodiversity, 2019
Predation is an important selective force that determines breeding success in all animals. Animals adopt a range of antipredatory strategies to overcome predation pressure in the breeding site, which is also a major predation ground.

Spatiotemporal variation and driving mechanisms of nest predation on Spotted Doves along an urbanization gradient

Avian Research
Nest predation is a critical driver of avian reproductive success, yet its response to urbanization remains controversial. Using infrared camera traps to monitor 133 artificial nests and 32 natural nests of the Spotted Dove (Spilopelia chinensis) along ...

Introduced mona monkey Cercopithecus mona is a key predator of bird nests in the endemic‐rich Príncipe Island

Conservation Science and Practice
Bird communities in oceanic islands tend to evolve under reduced predation, making them extremely susceptible to introduced predators. Príncipe Island (São Tomé and Príncipe, Central Africa) harbors 11 endemic bird species and eight introduced mammal ...

Does spatial variation in predation pressure modulate selection for aposematism?

Ecology and Evolution, 2017
It is widely believed that aposematic signals should be conspicuous, but in nature, they vary from highly conspicuous to near cryptic. Current theory, including the honest signal or trade‐off hypotheses of the toxicity–conspicuousness relationship ...

Mangrove Habitats in Zhanjiang of South China: A Potentially High‐Risk Environment for Breeding Birds

Ecology and Evolution
Nest predation is one of the most important causes of breeding failure in birds, and the risk of predation is closely related to nest site selection. To maximize site suitability, birds should choose safe locations for nest site to reduce the risk of ...

Camera traps unable to determine whether plasticine models of caterpillars reliably measure bird predation.

PLoS ONE
Sampling methods that are both scientifically rigorous and ethical are cornerstones of any experimental biological research. Since its introduction 30 years ago, the method of using plasticine prey to quantify predation pressure has become increasingly ...

Sentinel prey settings differ in their ability to distinguish organic from conventional apple orchards and in their sensitivity to weather conditions during field exposure

Biological Control
Determining factors that affect pest predation by natural enemies is essential for designing cropping systems that promote conservation biological control.

Habitat fragmentation alters post‐dispersal more than pre‐dispersal seed predation through edge effects

Ecosphere
In addition to causing loss of biodiversity, habitat fragmentation can alter species interactions. Relative to well‐studied effects of fragmentation on mutualistic interactions like pollination, effects on antagonistic interactions remain poorly ...

Keystone Predation: What Is It, and Is It Supported by Empirical Evidence?

Ecology and Evolution
Keystone predation is the process whereby a predator indirectly facilitates weak competitors by preferentially consuming strong competitors, often affecting local diversity.

Behavioral trade‐offs and multitasking by elk in relation to predation risk from Mexican gray wolves

Ecology and Evolution
Predator non‐consumptive effects (NCE) can alter prey foraging time and habitat use, potentially reducing fitness. Prey can mitigate NCEs by increasing vigilance, chewing‐vigilance synchronization, and spatiotemporal avoidance of predators. We quantified
