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.

Identification of a Novel 81-kDa Component of the Xenopus Origin Recognition Complex [PDF]
, 1998 The Xenopus origin recognition complex is essential for chromosomal DNA replication in cell-free extracts. We have immunopurified the Xenopus origin recognition complex with anti-Xorc2 antibodies and analyzed its composition and properties.

Potential cuckoo hosts have similar egg rejection rates to parasitized host species
Avian Research, 2020 Background Thrush species are rarely parasitized by cuckoos, but many have a strong egg recognition ability. To date, there is a limited understanding of the relationship between host egg rejection and cuckoo parasitism rate.

A Meta-Analysis of Avian Egg Traits Cueing Egg-Rejection Defenses Against Brood Parasitism
Frontiers in Ecology and Evolution, 2021 The capability of hosts to reject the odd egg from their nest is one of the key defenses against avian brood parasitism. Considerable research effort has been devoted to exploring which phenotypic traits of eggshells facilitate to cue the recognition of ...

Structural Basis of Egg Coat-Sperm Recognition at Fertilization [PDF]
Cell, 2017 Recognition between sperm and the egg surface marks the beginning of life in all sexually reproducing organisms. This fundamental biological event depends on the species-specific interaction between rapidly evolving counterpart molecules on the gametes.

Mechanisms of Sperm–Egg Interactions: What Ascidian Fertilization Research Has Taught Us
Cells, 2022 Fertilization is an essential process in terrestrial organisms for creating a new organism with genetic diversity. Before gamete fusion, several steps are required to achieve successful fertilization.

Protein-carbohydrate interactions during fertilization [PDF]
, 1998 Interaction between gametes during fertilization is at least in part regulated by carbohydrate moieties of the zona pellucida (ZP) and carbohydrate binding proteins of the sperm surface. This review focuses on the protein-carbohydrate interactions during

Egg recognition in Cinereous Tits (Parus cinereus): eggshell spots matter
Avian Research, 2019 Background Brood parasitic birds such as cuckoos (Cuculus spp.) can reduce their host’s reproductive success. Such selection pressure on the hosts has driven the evolution of defense behaviors such as egg rejection against cuckoo parasitism. Studies have

Helminth Eggs as a Magnetic Biomaterial: Introducing a Recognition Probe [PDF]
Frontiers in Veterinary Science, 2022 Parasitic helminths, despite their known negative impact (biomaterial) on human health and animal production, have fascinating features. In this study, we find fantastic magnetic properties in several forms: inductor [between 20.10 and 58.85 (±2.50) H], source of detectable electrical voltage [from +0.5 to 7.3 (±0.1) V, vs. the ground, GND, measured by

Improving the Accuracy and Precision of Egg Volume Measurement and Comparing Hoyt’s Equation and Troscianko’s Egg Volume Estimation for Gallinaceous Bird Species [PDF]
Poultry Science Journal, 2023 The recognition that egg volume variation has widespread implications in avian biology led us to test the accuracy and precision of the most commonly used egg volume determination methods.
