Decreased synaptic serotonin during depressive episodes is a central element of the monoamine hypothesis of depression. The serotonin transporter (5-HTT, SERT) is a key molecule for the control of synaptic serotonin levels. Here we aimed to detect st

Autor: Walter D. Koenig, Eric L. Walters, Jeffrey R. Walters, James S. Kellam, Klaus G. Michalek, Matthew S. Schrader

Publikováno v: The Condor. 107:810-822

We investigated patterns of seasonal variation in body weight in six populations of five resident species of temperate-zone woodpeckers: Acorn Woodpecker (Melanerpes formicivorus), Red-bellied Woodpecker (M. carolinus), Red-cockaded Woodpecker (Picoi

Monogamy with exceptions: Social and genetic mating system in a bird species with high paternal investment

Autor: Donald Blomqvist, Hans Winkler, Klaus G. Michalek, Peter Pechacek

Publikováno v: Behaviour. 142:1093-1114

Animal mating systems are strongly linked to costs and benefits associated with parental care. A high degree of male parental care may explain the occasional occurrence of social polyandry in some monogamous birds such as woodpeckers. We examined mat

PARENTAL CARE AND PARENTAGE IN MONOGAMOUS GREAT SPOTTED WOODPECKERS (PICOIDES MAJOR) AND MIDDLE SPOTTED WOODPECKERS (PICOIDES MEDIUS)

Autor: Hans Winkler, Klaus G. Michalek

Publikováno v: Behaviour. 138:1259-1285

Abstract Paternal effort is high in some monogamous mating systems. Trivers' (1972) model predicts that high male investment in brood care should evolve only when males have a high certainty of paternity. For this study, we chose two woodpecker speci

Classical polyandry found in the three-toed woodpecker Picoides tridactylus

Autor: Peter Pechacek, Hans Winkler, Donald Blomqvist, Klaus G. Michalek

Publikováno v: Journal of Ornithology. 147:112-114

We report two cases of simultaneous, social polyandry in the three-toed woodpecker Picoides tridactylus found in Berchtesgaden National Park, Germany during an 11-year study. The first case was between two neighbouring pairs in 2003. A female incubat
