Geographical variation in egg size dimorphism in rockhopper penguins
(Springer, 2010-04)
All crested penguins present a unique reversed hatching asynchrony: the larger second-laid egg (B-egg) hatches before the smaller first-laid egg (A-egg). Although both eggs often hatch, the A-chick generally dies of ...
Egg clutch survival under prolonged paternal care in a Glass Frog, Hyalinobatrachyum talamancae
(2020-04-11)
Previous studies have reported egg attendance as the most common protective behavior among the Neotropical frog family Centrolenidae. However, research on the effect of parental care and other factors thought to affect ...

A parental care-mating dilemma? Potential risks for offspring in the Pholcid spider when egg-carrying females accept mating
(Springer/Plenum Publishers, 2017-03)
Many species face a trade-off between additional mating opportunities and the offspring benefits (viability, quality) provided by parental care. Female Holocnemus pluchei spiders must abandon their egg-sac, which they ...
Parental investment in eggs and its effect on nestling growth and survival in Magellanic Penguins
(Csiro Publishing, 2014)
Life-history variables evolve in response to cost-benefit trade-offs. For birds, larger eggs are thought to be beneficial for development of offspring but are energetically costly to produce. Further, egg-size dimorphism ...
Egg clutch survival under prolonged paternal care in a glass frog, Hyalinobatrachium talamancae
(American Society of Ichthyologists and Herpetologists, 2020-09)
Previous studies have reported egg attendance as the most common protective behavior among the Neotropical frog family Centrolenidae. However, research on the effect of parental care and other factors thought to affect ...
Survival, physical and physiological changes of Taenia hydatigena eggs under different conditions of water stress
(Elsevier, 2017-06-24)
Taenia hydatigena eggs were investigated for morphological and physiological changes under water stress conditions. Fresh eggs were exposed at 31%, 47% and 89% of relative humidity (RH), and survival, size and ultrastructural ...
Egg hatching and survival of immature stages of Aedes aegypti (Diptera: Culicidae) under natural temperature conditions during the cold season in Buenos Aires, Argentina
(Entomological Society of America, 2017-01)
In temperate regions, the seasonal dynamics of Aedes aegypti (L) (Diptera: Culicidae) is mainly influenced by temperature. It is assumed that, during the winter season, the population remains as eggs and that the development ...
