Recent changes in bird populations in British broadleaved woodland

Carbon dioxide fluxes over an ancient broadleaved deciduous woodland in southern England

We present results from a study of canopyatmosphere fluxes of carbon dioxide from 2007 to 2009 above a site in Wytham Woods, an ancient temperate broadleaved deciduous forest in southern England. Gapfilled net ecosystem exchange (NEE) data were partitioned into gross primary productivity (GPP) and ecosystem respiration (Re) and analysed on daily, monthly and annual timescales. Over the continuo...

Europe’s bird populations in decline

Common birds: A study of bird populations in Europe found the most dramatic declines among common species such as the house sparrow (left) and starling. (Photo: Tomas Belka, birdphoto.eu.) From the sparrows picking our breadcrumbs from the ground to the swifts nesting in the tower, from the dawn chorus to the hoots of night-time hunters, birds are the most visible and audible group of wildlife ...

The role of translocation in recovery of woodland caribou populations.

Maintenance of viable populations of many endangered species will require conservation action in perpetuity. Efforts to conserve these species are more likely to be successful if their reliance on conservation actions is assessed at the population level. Woodland caribou (Rangifer tarandus caribou) were extirpated recently from Banff National Park, Canada, and translocations of caribou to Banff...

Changes in Breeding Bird Populations with Habitat Restoration in Northern Iowa

—Native tallgrass prairie and wetland habitat in the Prairie Pothole Region of the United States have declined over the past two centuries. Bird communities using these habitats have also experienced widespread declines that are often attributed to severe habitat loss and fragmentation. We estimated the change, or turnover, in bird populations in the Eagle Lake Wetland Complex, Iowa, with ongoi...
