Egg Discrimination in the Yellowhammer [PDF]

open access: yesThe Condor, 2004
AbstractIn a coevolutionary arms race between a brood parasite and its host, both species evolve adaptations and counteradaptations, such as egg mimicry and egg discrimination. The Yellowhammer (Emberiza citrinella) is a minor host of the Common Cuckoo (Cuculus canorus) in Europe.

Isotopic and Elemental Fingerprint of Edible Egg Parts—The Health Risk Assessment Based on Potentially Toxic Elements Content

open access: yesMolecules, 2023
The present study investigated the isotopic and elemental profile (by IRMS and ICP–MS) of edible egg parts (29 egg whites and 29 yolks) mainly collected from Romania.

Egg Freshness Evaluation Using Transmission and Reflection of NIR Spectroscopy Coupled Multivariate Analysis

open access: yesFoods, 2021
This work presents a novel work for the detection of the freshness of eggs stored at room temperature and refrigerated conditions by the near-infrared (NIR) spectroscopy and multivariate models. The NIR spectroscopy of diffuse transmission and reflection

Only Females Oviposit: Chemical Discrimination of Adult Stink Bug Sex by the Egg Parasitoid Trissolcus japonicus

open access: yesFrontiers in Ecology and Evolution, 2021
Egg parasitoids foraging for suitable hosts scattered in the environment rely mainly on chemical cues. Elucidating the chemical ecology of natural enemies is important in the development of effective and successful strategies for conservation biological ...

Assessment of egg and milk allergies among Indians by revalidating a food allergy predictive model

open access: yesWorld Allergy Organization Journal, 2022
Background: The recent upsurge in food allergy indicates the need for accurate medical diagnostics. The application of predictive diagnostic models can envisage the outcome of oral food challenge (OFC), reducing cost and time. A logistic regression model

Ultraviolet reflectance of great spotted cuckoo eggs and egg discrimination by magpies [PDF]

open access: yesBehavioral Ecology, 2005
Hosts of obligate avian brood parasites use visual cues to distinguish between their own eggs and those of the parasite. Despite major differences between human and bird vision, most previous studies on cuckoo egg mimicry estimated color matching based on human color vision.

Could a Factor That Does Not Affect Egg Recognition Influence the Decision of Rejection? [PDF]

open access: yesPLoS ONE, 2015
Rejection of the parasitic egg is the most important defence of hosts against brood parasites. However, this response is variable among and within species, and egg discrimination is not always followed by egg rejection.

From food to offspring down: tissue-specific discrimination and turn-over of stable isotopes in herbivorous waterbirds and other avian foraging guilds. [PDF]

open access: yesPLoS ONE, 2012
Isotopic discrimination and turn-over are fundamental to the application of stable isotope ecology in animals. However, detailed information for specific tissues and species are widely lacking, notably for herbivorous species.

How to evade a coevolving brood parasite: egg discrimination versus egg variability as host defences [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2011
Arms races between avian brood parasites and their hosts often result in parasitic mimicry of host eggs, to evade rejection. Once egg mimicry has evolved, host defences could escalate in two ways: (i) hosts could improve their level of egg discrimination; and (ii) negative frequency-dependent selection could generate increased variation in
