Leaves that walk and eggs that stick: comparative functional morphology and evolution of the adhesive system of leaf insect eggs (Phasmatodea: Phylliidae)
Phylliidae are herbivorous insects exhibiting impressive cryptic masquerade and are colloquially called “walking leaves”. They imitate angiosperm...

Avian Reproduction: Timing, Anatomy, and Eggs
For successful reproduction, timing is important because food availability for birds varies with time of year and, to ensure sufficient food for both...

Sister predatory mites collectively protect their eggs against predators
Group-living animals sometimes cooperatively protect their offspring against predators. This behavior is observed in a wide range of taxa but, to the...

Predation of sea turtle eggs by rats and crabs
Egg predation by invasive and native species may have severe impacts on endangered species and negatively affect species recovery. We assessed the...

Effects of age and eggshell thickness on the hatching results of stored broiler breeder eggs
The present study was conducted to determine the effects of breeder age and eggshell thickness on the hatching results of broiler breeders. A total...

Heterogeneity in maternal mRNAs within clutches of eggs in response to thermal stress during the embryonic stage
BackgroundThe origin of variation is of central interest in evolutionary biology. Maternal mRNAs govern early embryogenesis in many animal species,...
-
Maternal patterns of inheritance alter transcript expression in eggs
BackgroundModifications to early development can lead to evolutionary diversification. The early stages of development are under maternal control, as...

Where and Why do Females of the Parasitic Fly Istocheta aldrichi Lay Their Eggs on the Body of Adult Japanese Beetles?
Egg-laying decisions by female insects should balance aspects related to immature survival and foraging profitability of emerging larvae. Using...

Efficiency of female age of egg parasitoids on parasitism of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) eggs of various ages
The use of egg parasitoids in the biological control of insect pests is a promising technique in integrated pest management. However, there is little...

Eggs of the bee Osmia lignaria endure weeks of prolonged cold weather
Our insights into the responses of immature stages of vernal solitary bees to the thermal challenges of spring weather mostly come from studies of...

Quality of fish eggs and production of androgenetic and gynogenetic doubled haploids (DHs)
Induced development of haploid embryos (H) with only paternal (androgenesis) or maternal (gynogenesis) chromosomes requires irradiation of eggs...

Temporary division of roles in group hunting for fish eggs by a coral reef fish
Division of roles was observed during group hunting by the false cleanerfish, Aspidontus taeniatus (Blenniidae), when they raid the nests of the...

Polymorphism of the pre-gga-miR-24* Gene and White-Creamy-Brown Coloration of Chicken Eggs
AbstractTwo pigments are mainly responsible for the eggshell color of poultry eggs: protoporphyrin IX and biliverdin. It is considered that...
