The Perceptual and Cognitive Processes That Govern Egg Rejection in Hosts of Avian Brood Parasites
Frontiers in Ecology and Evolution, 2021 Hosts of avian brood parasites are under intense selective pressure to prevent or reduce the cost of parasitism. Many have evolved refined egg discrimination abilities, which can select for eggshell mimicry in their parasite.

Implementation of an extended ZINB model in the study of low levels of natural gastrointestinal nematode infections in adult sheep [PDF]
, 2016 Background: In this study, two traits related with resistance to gastrointestinal nematodes (GIN) were measured in 529 adult sheep: faecal egg count (FEC) and activity of immunoglobulin A in plasma (IgA).

Blunt egg pole holds cues for alien egg discrimination: experimental evidence
Journal of Avian Biology, 2010 Eggshell colour patterns play a crucial role in avian host–parasite coevolution. In contrast to many experiments investigating general host egg discrimination abilities, studies testing where specific recognition cues are located on the eggshells (on ...

Does nest sanitation elicit egg rejection in an open-cup nesting cuckoo host rejecter?
Avian Research, 2018 Background Nest sanitation behavior is one of the most important means to ensure high reproductive efficiency. In avian brood parasitism, nest sanitation behavior may be a pre-adaptation of host birds that allows them to identify the parasitic eggs, so ...

Comparison of spectral and image morphological analysis for egg early hatching property detection based on hyperspectral imaging. [PDF]
PLoS ONE, 2014 The use of non-destructive methods to detect egg hatching properties could increase efficiency in commercial hatcheries by saving space, reducing costs, and ensuring hatching quality.

No evidence of host-specific egg mimicry in Asian koels.
PLoS ONE, 2021 Avian brood parasitism is costly for the host, in many cases leading to the evolution of defenses like discrimination of parasitic eggs. The parasite, in turn, may evolve mimetic eggs as a counter-adaptation to host egg rejection.

Foods, 2023 Eggs that are produced using organic methods retail at higher prices than those produced using conventional methods, but they cannot be differentiated reliably using visual methods. Eggs can therefore be fraudulently mislabeled in order to increase their

I love my children: am I racist? On the wish to be biologically related to one’s children [PDF]
, 2018 Is the wish to be biologically related to your children legitimate? Here, I respond to an argument in support of a negative answer to this question according to which a preference towards having children one is biologically related to is analogous to a ...

Nestling discrimination and feeding habits during brooding of Chestnut Thrushes
Avian Research, 2020 Background Nestling discrimination and feeding habits during brooding are important factors affecting host selection of parasitic birds. Some host birds can avoid being parasitized by discriminating their nestlings or feeding food not suitable for ...
