Published: 29 March 2023
...Samuel P. Caro; Ségolène Delaitre; Bruno Buatois; Francesco Bonadonna; Jessica L. Graham ABSTRACT Many organisms rely on environmental cues to predict and anticipate the annual optimal timing of reproduction. In insectivorous birds, preparation for breeding often coincides with the time vegetation...

...Anna Cressman; Etya Amsalem ABSTRACT Carbon dioxide (CO 2 ) is commonly used to immobilize insects and to induce reproduction in bees. However, despite its wide use and potential off-target impacts, its underlying mechanisms are not fully understood. Here, we used Bombus impatiens to examine...

...Victoria S. Farrar; Jaime Morales Gallardo; Rebecca M. Calisi ABSTRACT In the face of challenges, animals must balance investments in reproductive effort versus their own survival. Physiologically, this trade-off may be mediated by glucocorticoid release by the hypothalamic–pituitary–adrenal axis...

... of endogenous rhythms). Restricted food availability times may, for example, constrain reproductive output by limiting the number or quality of offspring or the number of reproductive attempts, as has been observed for nesting frequency in birds. Consuming food at the wrong time of day reduces the reproductive...

...Neelu Anand Jha; S. K. Tahajjul Taufique; Vinod Kumar ABSTRACT We investigated the consequence of no-night environment (constant light, LL) on reproductive performance in zebra finches in the parent (P) and subsequent (F1) generation. As a measure of the overall effects on metabolic reproductive...

... on the survival and reproductive function of H. graminicola . Our study thus provides clear evidence that low plasticity with fast development to a certain size means a high nutritional requirement for protein at a cost of lower survival and prolonged time to egg laying when prey have low protein-to-lipid content...

... Reproduction Evolution Neural substrates Few decisions in life are more consequential for individual fitness than choosing a mate. Mate choice (see Glossary) is the result of selectively mating with only some individuals of the opposite sex, whose members compete for fertilization opportunities...

... the ambient photoperiod. The objective of this study was to characterize the effects of photoperiodic variation on metabolic and reproductive traits, and the related changes in pituitary–hypothalamic gene expression in MSM mice. MSM mice were kept in long (LP) or short photoperiod (SP) for 6 weeks. Our...

... egg layers and workers, which specialize in non-reproductive tasks inside and outside their nest. For instance, reproductives are more resistant to starvation, and changes in fat content have been associated with the transition from inside to outside work or reproductive activities. However, most...
