Seasonal increase in nest defense, but not egg rejection, in a cuckoo host
The interactions between avian brood parasites and their hosts provide an informative and easy-to-handle system for studying coevolution. Avian brood parasitism reduces the reproductive success of hosts, and thus, hosts have evolved anti-parasitic ...

Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

We studied the frequency and ecological correlates of intraspecific brood parasitism, physical transfer of eggs between nests, and destruction of eggs by conspecifics in colonially nesting Cave Swallows (Petrochelidon fulva) and Cliff Swallows (P ...

Grazing Impact on Brood Parasitism in the Black-Capped Vireo
Grazing facilitates foraging opportunities for brown-headed cowbirds (Molothrus ater), an obligate brood parasite. Cowbirds can reduce productivity of their hosts, causing some host species to decline in abundance.

The costs of extra‐pair behaviours in birds
ABSTRACT Extra‐pair behaviours – reproductive behaviours, including those related to copulation and paternity of offspring, amongst animals outside of a social pair bond – have long intrigued behavioural ecologists, particularly from the female animal's perspective.

Brood parasitism by shiny cowbirds
Brood parasitic birds lay eggs amongst the clutches of other species, which then assume all costs of parental care on their behalf. This thesis addresses several puzzles of avian brood parasitism, using field studies and theoretical modelling of the generalist parasite, the shiny cowbird (Molothrus bonariensis) and select hosts in Argentina.

Game theoretic model of brood parasitism in a dung beetle Onthophagus Taurus [PDF]
We present a game theoretic model of brood parasitism in the dung beetle Onthophagus taurus. Female O. taurus engage in brood parasitism when they attack a brood ball made by another female, destroy the existing egg and place one of their own eggs to ...

There has been great interest in how complex social behaviours such as cooperative breeding evolve and are maintained; however, it is still unclear what exact phenomena trigger the transition to cooperative breeding.
