Clutch size but not egg size associates with migration distance in South American land birds
The association between migratory strategies and life-history traits helps explain how migratory organisms balance the energetic costs and survival...
-
Reproductive ecology of treefrogs: egg size promotes reproductive effort differences between females
Reproductive patterns observed in organisms are direct outcomes of the interaction among parameters such as phylogeny, body size, and environmental...

Proximate determinants of family size in an obligate egg-feeding frog
The number of offspring parents rear varies considerably among closely related lineages, individuals, and even reproductive events by one individual....

Relationships between egg size and maternal size, life history forms, and habitats of Greenlandic Arctic charr (Salvelinus alpinus)
Arctic charr ( Salvelinus alpinus [L.] complex) has been widely used as a model system for studies in evolutionary ecology because of its diversity in...

Egg components and offspring survival vary with group size and laying order in a cooperative breeder
Prenatal resource allocation to offspring can be influenced by maternal environment and offspring value, and affect offspring survival. An important...

Benefits of intertidal development and large egg size in a marine toadfish
The environments in which offspring are reared can profoundly affect their development, growth, and survival. Certain specialized fish species...

Egg Biology of Insect Predators
Life begins as an autonomous egg in the majority of insects. Ovarian reproduction is the term for this process. Each egg is created within the...

Egg size–related traits during the first year of growth and smolting in hatchery and wild juveniles of steelhead trout Oncorhynchus mykiss
Within-clutch variation in the size or the amount of yolk in the egg has been widely studied because of its importance for both maternal and...

Reproductive Strategy of the Annual Fish Leptopanchax Opalescens (Rivulidae) and Trade-Off Between Egg Size and Maximum Body Length in Temporary Wetlands
Leptopanchax opalescens is a critically endangered small annual fish. Reproductive traits of this species were studied to improve our understanding...

Effect of paternal life-history form and egg size on offspring life-history traits in masu salmon Oncorhynchus masou
To clarify the effect of paternal life-history form and egg size on offspring life-history traits (e.g., growth and maturation) in masu salmon ( Oncorh...

Influence of Dietary Probiotic and Alpha-Monolaurin on Performance, Egg Quality, Blood Constituents, and Egg Fatty Acids’ Profile in Laying Hens
This work was designed to evaluate the advantages of using multi-strain probiotics feed ( Bacillus subtilis, Bacillus licheniformis and Clostridium...

Investing in a nest egg: intraspecific variation in the timing of egg laying across a latitudinal gradient
Avian reproductive strategies vary widely, and many studies of life-history variation have focused on the incubation and hatching stages of nesting....

Ultraviolet coloration of avian parasitic egg does not cue egg rejection in the common redstart host
Avian brood parasite hosts can use distinct egg traits to recognize a parasitic egg. Previous studies suggested an important role of eggshell...

Density-dependent selection in Drosophila: evolution of egg size and hatching time
Many different laboratory studies of adaptation to larval crowding in Drosophila spp. have all yielded the evolution of pre-adult competitive...

Different egg size in the chrysanthemum lace bug Corythucha marmorata (Hemiptera: Tingidae) in response to novel host plant cultivars
The chrysanthemum lace bug Corythucha marmorata (Uhler) (Hemiptera: Tingidae) is a North American insect that has become invasive in Japan. While it...

Prenatal manipulation of yolk androgen levels affects egg size but not egg colour in a songbird
AbstractMaternal allocation of androgens to the egg yolk allows mothers to adaptively manipulate offspring phenotype. Increases of egg androgen...

Reviewing and improving spatiotemporal modeling approaches for mackerel’s total annual egg production
Since the late 1970s the international ICES mackerel egg survey takes place in the Northeast Atlantic to obtain an estimate of total annual egg...

Influence of fall armyworm Spodoptera frugiperda egg mass scales and layers on the performance of three species of egg parasitoid Trichogramma with different ovipositor lengths
BackgroundThe fall armyworm (FAW), Spodoptera frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) is a highly polyphagous and destructive pest of maize...

How competition between overlap** generations can influence optimal egg-laying strategies in annual social insects
Annual social insects are an integral functional group of organisms, particularly in temperate environments. An emblematic part of their annual cycle...
