Projecting Impacts of Fire Management on a Biodiversity Indicator in the Sierra Nevada and Cascades, USA: The Black-Backed Woodpecker
In the Sierra Nevada and southern Cascade ranges of California and Oregon, a genetically distinct population of the black-backed woodpecker has become rare due, in part, to fire suppression. This species is considered an indicator species for its primary habitat: early successional burned forests with an abundance of standing dead trees. Fuel reduction treatments such as post-fire logging, and ...
متن کاملExtrapair Paternity and Maternity in the Three-Toed Woodpecker, Picoides tridactylus: Insights from Microsatellite-Based Parentage Analysis
Molecular techniques have revealed that avian mating systems are more diverse and complex than previously thought. We used microsatellite markers to determine genetic parentage, the prevalence of extrapair paternity and quasi-parasitism (i.e. situations where a male's extrapair mate lay in his nest) in a socially monogamous population of three-toed woodpeckers (Picoides tridactylus) in southern...
متن کاملLogging affects the white-backed woodpecker Dendrocopos leucotos distribution in the Białowieża Forest
The white-backed woodpecker (WbW) is a critically endangered species in Europe. The Białowieża Forest (BF) is of major importance for its conservation. Distribution of WbW in deciduous stands of the BF was studied in relation to habitat resources. In March–April 2005 we replicated a 1991 study where the WbW population was estimated using playback drumming techniques. Woodpeckers were recorded i...
متن کاملUnexpected Strong Polygyny in the Brown-Throated Three-Toed Sloth
Promiscuous mating strategies are much more common than previously appreciated. So much so, that several authors have proposed that promiscuity is the "rule" rather than the exception in vertebrate mating systems. Decreasing species mobility and increasing habitat fragmentation have both been suggested to reduce the "polygyny potential" of the environment and promote other mating strategies lik...
متن کاملPentobarbital anaesthesia in the Herring and Lesser Black-backed Gull.
A procedure for long lasting general anaesthesia in gulls (LaTus sp.) is described. It is based on an initial basal intramuscular dose of pentobarbital sodium, supplemented if necessary by intravenous injection to effect of the same agent. Additional intramuscular pentobarbital is used to extend the duration of anaesthesia. The labile respiration of the birds is supported with oxygen. In cases ...
