Research on image recognition of cracked eggs based on convolutional neural network model

open access: yesShipin yu jixie, 2023
Objective: In order to improve the accuracy and operating efficiency of the egg crack detection method based on computer vision. Methods: Used poultry egg simulation impact equipment to obtain cracked eggs, and collected images of cracked eggs and intact

A review of the cues used for rejecting foreign eggs from the nest by the Eurasian blackbird (Turdus merula)

open access: yesEcology and Evolution, 2022
Avian brood parasitism is reproductively costly for hosts and selects for cognitive features enabling anti‐parasitic resistance at multiple stages of the host's breeding cycle.

Reject the odd egg: egg recognition mechanisms in parrotbills [PDF]

open access: yesBehavioral Ecology, 2014
Studies of the behavior of animals when confronted with tasks differing in complexity can improve our understanding of animal cognition and learning mechanisms. Coevolutionary interactions between brood parasites and their hosts provide an ideal opportunity for studying animal cognition because egg recognition and rejection are some of the most ...

Egg and sperm recognition systems during fertilization [PDF]

open access: yesDevelopment, Growth & Differentiation, 2008
Fertilization is a programmed process that has many molecules and sequential events amenable to study. The biochemistry of fertilization has identified cellular and acellular components fundamental to the interactions between sperm and egg. Recent studies highlight the molecular details of the species‐specificity of fertilization that involve protein ...

Deep learning enhanced terahertz imaging of silkworm eggs development

open access: yesiScience, 2021
Summary: Terahertz (THz) technology lays the foundation for next-generation high-speed wireless communication, nondestructive testing, food safety inspecting, and medical applications. When THz technology is integrated by artificial intelligence (AI), it

Gradual changes in model shape affect egg-directed behaviours by parasitic shiny cowbirds Molothrus bonariensis in captivity

open access: yesRoyal Society Open Science, 2023
Eggs are critically important for avian reproduction as all birds are oviparous. Accordingly, the recognition and care of own eggs represent the cornerstones of avian breeding, whereas the elimination of foreign objects, including brood-parasitic eggs ...

Molecular evolution of candidate male reproductive genes in the brown algal model Ectocarpus [PDF]

open access: yes, 2016
Background: Evolutionary studies of genes that mediate recognition between sperm and egg contribute to our understanding of reproductive isolation and speciation. Surface receptors involved in fertilization are targets of sexual selection, reinforcement,

Egg discrimination along a gradient of natural variation in eggshell coloration [PDF]

open access: yes, 2017
Accurate recognition of salient cues is critical for adaptive responses, but the underlying sensory and cognitive processes are often poorly understood. For example, hosts of avian brood parasites have long been assumed to reject foreign eggs from their ...

Which egg features predict egg rejection responses in American robins? : replicating Rothstein's (1982) study [PDF]

open access: yes, 2018
Rothstein (Behavioral Ecology and Sociobiology, 11, 1982, 229) was one of the first comprehensive studies to examine how different egg features influence egg rejection behaviors of avian brood parasite-hosts.

Insect egg-induced innate immunity: Who benefits?

open access: yesPLoS Pathogens, 2023
Plants perceive the presence of insect eggs deposited on leaves as a cue of imminent herbivore attack. Consequential plant signaling events include the accumulation of salicylic acid and reactive oxygen species, transcriptional reprogramming, and cell ...
