Offspring retrieval behaviors after brood loss in the convict cichlid
… young in response to complete or catastrophic brood loss. This retrieval behavior is important for both parents because parents, especially the males, have been observed to abandon their mate and brood when it does not appear to be successful. </p> <p>Because brood loss in a natural setting …

Lifetime fitness and changing life history traits in Red-cockaded Woodpeckers
… time including lay date, clutch size, partial brood loss, and survival to year one. These traits were strongly influenced by local climate variables at each study site, but it is not clear that climate has changed over time at the study sites to account for all the observed changes in life …

Brood ecology and population dynamics of King Eiders
… of nest success. To gain insight into King Eider brood ecology I, respectively, monitored 111 and 46 individually-marked ducklings from broods of 23 and 11 radio-marked King Eiders during 2000 and 2001. Total brood loss accounted for 84% of all duckling mortality with most brood loss (77%) less …

Life history trade-offs in a parental care-providing fish: the role of reproductive value, predation threat, and physiological condition on brood abandonment decisions by paternal largemouth bass
… the decision by a parent to abandon their brood. I performed two separate, yet complementary, studies to test for the effects of several factors on brood abandonment decisions in largemouth bass (Micropterus salmoides); a model parental care-providing species. First, I tested whether mating …

Impacts of population-level reproductive success on recruitment dynamics in largemouth bass (Micropterus salmoides)
… higher embryonic mortality rates through brood predation, it is unclear whether or not variation in reproductive success across a population is an important driver of recruitment. Density-dependent survival of age-0 Largemouth Bass after parental care ceases may compensate for variation in …

Bioacoustics and reproductive ecology of the damselfish Dascyllus albisella
… selective pressure for synchronous spawning when brood size, brood loss, and brood failure were considered. It is possible, though currently untestable, that there is a benefit of synchronous spawning for larval survival. It is unlikely that reproduction is synchronized in response to an …
