DOI: 10.1002/ece3.9427
Abstract: Abstract Maternal effects have the potential to alter early developmental processes of offspring and contribute to adaptive diversification. Egg size is a major contributor to offspring phenotype, which can influence developmental trajectories and potential resource… read more here.

DOI: 10.1007/s00265-017-2289-1
Abstract: Shiny cowbirds (Molothrus bonariensis) are generalist brood parasites that use hosts varying in body and egg size. On the contrary, screaming cowbirds (M. rufoaxillaris), which are larger than shiny cowbirds, are host specialist that use… read more here.

DOI: 10.1016/j.ygcen.2018.07.019
Abstract: The measurement of corticosterone levels in feathers (fCort) is gaining recognition as an effective means for describing links between stages of the annual cycle in birds. Many seabirds are especially good models for exploring these… read more here.

Geographic variation in maternal investment and trade-offs between egg size and clutch size in an endemic toad of the Qinghai-Tibet Plateau

DOI: 10.1038/s41598-020-63635-y
Abstract: Life history theory predicts that animals often produce fewer offspring of larger size and indicate a stronger trade-off between the number and size of offspring to cope with increasing environmental stress. In order to evaluate… read more here.

DOI: 10.1093/cz/zoac037
Abstract: Abstract In the coevolutionary interactions between avian brood parasites and their hosts, egg recognition based on color and/or pattern is a common and effective defense to counter parasitism. However, for egg recognition based on size,… read more here.

DOI: 10.1111/geb.12748
Abstract: Methods: We compiled the largest geo-located dataset of marine fish egg size (diameter) to date (n51,078 observations; 192 studies; 288 species; 242 localities). We decomposed sea surface temperature (SST) and chlorophyll-a time series into mean… read more here.

DOI: 10.1111/jav.02356
Abstract: In many birds, there is significant variation in egg size both across and within clutches that remains to be explained. Birds lay one egg per day and in hot climates, the first laid eggs may… read more here.

Egg‐size plasticity in Apis mellifera: Honey bee queens alter egg size in response to both genetic and environmental factors
Sign Up to like & getrecommendations! Published in 2020 at "Journal of Evolutionary Biology"
DOI: 10.1111/jeb.13589
Abstract: Social evolution has led to distinct life‐history patterns in social insects, but many colony‐level and individual traits, such as egg size, are not sufficiently understood. Thus, a series of experiments was performed to study the… read more here.

Replicated latitudinal clines in reproductive traits of European and North American yellow dung flies
Sign Up to like & getrecommendations! Published in 2018 at "Oikos"
DOI: 10.1111/oik.05421
Abstract: Geographic variation in phenotypic traits is commonly correlated with spatial variation in the environment, e.g. seasonality and mean temperature, providing evidence that natural selection generates such patterns. In particular, both body size and egg size… read more here.

Abstract: Simple Summary How parents control the sex of their offspring greatly differs in the animal kingdom. Two lineages in the Thrips tabaci Lindeman cryptic species complex exhibit arrhenotokous haplodiploidy, which enables parents to influence the… read more here.
