Relationships between egg-recognition and egg-ejection in a grasp-ejector species. [PDF]
PLoS ONE, 2017 Brood parasitism frequently leads to a total loss of host fitness, which selects for the evolution of defensive traits in host species. Experimental studies have demonstrated that recognition and rejection of the parasite egg is the most common and ...

Egg Spots Are Important Cues for Egg Recognition in Barn Swallows [PDF]
Ecology and EvolutionEgg recognition is one of the most common strategies utilized by host birds to combat brood parasitism. Eggshell surface features (e.g., eggshell color and spots) are important cues for host egg recognition, enabling avian hosts to recognize and reject ...

Parasitic egg recognition using convolution and attention network [PDF]
Scientific Reports, 2023 Intestinal parasitic infections (IPIs) caused by protozoan and helminth parasites are among the most common infections in humans in low-and-middle-income countries. IPIs affect not only the health status of a country, but also the economic sector.

Model eggs fail to detect egg recognition in host populations after brood parasitism is relaxed [PDF]
Frontiers in Zoology, 2020 Background Obligate brood parasites exert strong selective pressure on target hosts. In response, hosts typically evolve anti-parasitism strategies, of which egg recognition is one of the most efficient.

Brood parasitism and egg recognition in three bunting hosts of the cuckoos [PDF]
Ecology and Evolution, 2023 Comparative studies of egg recognition and rejection between various sympatric hosts provide insight into the coevolutionary history of the hosts and parasites, as well as the degree of antagonism between the species.

Egg rejection and egg recognition mechanisms in Oriental Reed Warblers [PDF]
Avian Research, 2021 Background Nest parasitism by cuckoos (Cuculus spp.) results in enormous reproductive failure and forces hosts to evolve antiparasitic strategies, i.e., recognition of own eggs and rejection of cuckoo eggs.

Find and fuse: Unsolved mysteries in sperm-egg recognition. [PDF]
PLoS Biol, 2020 Sexual reproduction is such a successful way of creating progeny with subtle genetic variations that the vast majority of eukaryotic species use it. In mammals, it involves the formation of highly specialised cells: the sperm in males and the egg in females, each carrying the genetic inheritance of an individual.

Egg recognition: The importance of quantifying multiple repeatable features as visual identity signals. [PDF]
PLoS ONE, 2021 Brood parasitized and/or colonial birds use egg features as visual identity signals, which allow parents to recognize their own eggs and avoid paying fitness costs of misdirecting their care to others' offspring.

The limits of egg recognition: testing acceptance thresholds of American robins in response to decreasingly egg-shaped objects in the nest [PDF]
Royal Society Open Science, 2021 Some hosts of avian brood parasites reduce or eliminate the costs of parasitism by removing foreign eggs from the nest (rejecter hosts). In turn, even acceptor hosts typically remove most non-egg-shaped objects from the nest, including broken shells ...

Contrasting effects of egg size and appearance on egg recognition and rejection response by Oriental reed warblers [PDF]
Ecology and Evolution, 2020 Background Among potential hosts, the rejection of foreign eggs, which is a common and effective strategy to counter brood parasitism, depends on egg recognition.
