Nest-site preference and maternal effects on offspring growth
Maternal preferences for oviposition sites are assumed to be adaptive, but offspring fitness is not always higher at preferred sites and, thus, further study of the selection pressures that influence oviposition behavior is warranted. Among birds, predation is regarded as the primary agent of selection on nest-site microhabitat preferences, but alternatives are rarely considered. We tested the ...
متن کاملIncorporating density dependence into the oviposition preference-offspring performance hypothesis.
1. Although theory predicts a positive relationship between oviposition preferences and the developmental performance of offspring, the strength of this relationship may depend not only on breeding site quality, but also on the complex interactions between environmental heterogeneity and density-dependent processes. Environmental heterogeneity may not only alter the strength of density dependen...
متن کاملIntraguild Predation and Native Lady Beetle Decline
Coccinellid communities across North America have experienced significant changes in recent decades, with declines in several native species reported. One potential mechanism for these declines is interference competition via intraguild predation; specifically, increased predation of native coccinellid eggs and larvae following the introduction of exotic coccinellids. Our previous studies have ...
متن کاملPredation by adult and larval lady beetles (Coleoptera: Coccinellidae) on initial contact with lady beetle eggs.
Naïve adults and larvae of the native lady beetles Coleomegilla maculata (DeGeer), Cycloneda munda (Say), Hippodamia convergens Guérin-Méneville, Olla v-nigrum (Mulsant), and the exotic lady beetle Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) were tested for their initial response to eggs of these five lady beetle species and for egg consumption on first contact and after 3 h. Additio...
متن کاملEffects of maternal nutrition on conceptus growth and offspring performance: implications for beef cattle production.
Developmental programming is the concept that a maternal stimulus or insult at a critical period in fetal development has long-term effects on the offspring. Historically, considerable effort has been made to understand how nutrition influences health and productivity during the postnatal period. Whereas maternal nutrition during pregnancy plays an essential role in proper fetal and placental d...
