Interactive effects of arrival date, territory quality and male polyterritorial behaviour on the mating system of the sedge warbler Acrocephalus schoenobaenus: a path analysis

Autor: Wojciech Bielański, Adam M. Ćmiel, Tadeusz A. Zając

Publikováno v: Journal of Avian Biology, Vol 2022, Iss 11-12, Pp n/a-n/a (2022)

Classical models predict that male fitness is based on resources monopolized and invested in reproduction, and/or on individual quality providing offspring with sexually attractive traits or viable genes. However, these factors are frequently correla

Long‐term annual and spatial variation of polygyny in the white‐throated dipper (Cinclus cinclus)

Autor: Bjørn Walseng, Joël M. Durant, Dag O. Hessen, Kurt Jerstad, Anna L. K. Nilsson, Ole W. Røstad, Tore Slagsvold

Publikováno v: Ecology and Evolution, Vol 12, Iss 10, Pp n/a-n/a (2022)

Abstract Mating strategies are key components in the fitness of organisms, and notably in birds the occurrence of monogamy versus polygyny has attracted wide interest. We address this by a very comprehensive dataset (2899 breeding events spanning the

Implications of non-ideal occupancy for the measurement of territory quality

Autor: Kate A. McGinn, Fidelis A. Atuo, Gavin M. Jones, Brendan K. Hobart, Douglas J. Tempel, Sheila A. Whitmore, William J. Berigan, R.J. Gutiérrez, M. Zachariah Peery

Publikováno v: Global Ecology and Conservation, Vol 35, Iss , Pp e02097- (2022)

Territory quality shapes population dynamics and has conservation implications for territorial species. Yet, quantifying territory quality using different measures can yield conflicting results, particularly if territory selection is non-ideal, thus

Breeding dispersal in a resident boreal passerine can lead to short‐ and long‐term fitness benefits

Autor: Matthew Fuirst, Dan Strickland, D. Ryan Norris

Publikováno v: Ecosphere, Vol 12, Iss 9, Pp n/a-n/a (2021)

Abstract Whether an individual disperses or remains site‐faithful between breeding seasons can have important impacts on individual fitness and population dynamics. While several studies have identified factors influencing the probability of breedi
