Mate guarding and territorial aggression vary with breeding synchrony in golden whistlers (Pachycephala pectoralis)
(SPRINGER, 2008-06)
Male paternity assurance behaviour during the
female fertile period has been widely documented amongst
birds. In contrast, how sex-specific behavioural strategies
vary with local breeding synchrony levels remains ...
Synchrony does not explain extrapair paternity rate variation in northern or southern house wrens
(Oxford Univ Press Inc, 2010-04)
Rates of extrapair paternity (EPP) vary widely among and within bird species, and 2 hypotheses suggest that this variation is driven by variation in breeding synchrony. These hypotheses make contradictory predictions, and ...
Temperate-Tropical Variation in Breeding Synchrony and Extra-Pair Paternity Among New World Tachycineta Swallows
(Nature Publishing Group, 2019-09)
Extra-pair paternity rates vary markedly across avian taxa, but patterns of variation in this trait have been obscured by a paucity of data on closely related species, especially those spanning broad environmental gradients. ...
Ecological opportunities and individual condition as predictors of extra-pair paternity in a south-temperate swallow (Tachycineta leucorrhoa)
(Wiley Blackwell Publishing, Inc, 2018-09)
Ecological and physiological factors such as breeding density, breeding synchrony, and adult body condition can all affect extra-pair mating behavior, but the relative importance of these factors may vary among species. ...
Seasonal decline in breeding performance of the Kelp Gull Larus dominicanus
(Pacific Seabird Group, 2008-12)
The effects of timing of breeding on reproductive parameters of Kelp Gulls Larus dominicanus were studied in Patagonia, Argentina, during 1998 and 1999. Yearly and spatial variation in the study were assessed by sampling ...
Effect of a 12-h increment in the short-term treatment regimen on ovarian status, estrus synchrony, and pregnancy rate in artificially inseminated dairy goats
(Elsevier B.V., 2020-10-01)
This study was conducted to assess effects of two hormonal treatments on ovarian follicular status, estrous synchrony and fertility in dairy goats during the non-breeding season when duration of progestogen device use ...
O papel do sistema reprodutivo na distribuição de três espécies de Microlicia (Melastomataceae)
(Universidade Estadual Paulista (Unesp), 2022-12-07)
A família Melastomataceae é composta por espécies com diversas estratégias reprodutivas, podendo ser autocompatíveis, apomíticas ou autoincompatíveis. Dentre elas o gênero Microlicia possui alto grau de endemismo na Serra ...
Extrapair paternity in two populations of the socially monogamous Thorn-tailed Rayadito Aphrastura spinicauda (Passeriformes: Furnariidae)
(Wiley, 2020)
Studies on extrapair paternity (EPP) are key to understanding the ecological and evolutionary drivers of variation in avian mating strategies, but information is currently lacking for most tropical and subtropical taxa. ...
