Wildlife managers routinely survey age and gender compositions of elk (Cervus elaphus) during winter to assess population demographics and to prescribe and evaluate harvest strategies. We measured precision of replicated field classifications of antlerless elk conducted during 1996-1999 on the National Elk Refuge, Wyoming. We found classification discrepancies of 14% for elk calves. Next we exa...

Ecosystem services (ES) have been well studied in most biomes, but the Arctic tundra has received little attention, despite covering over 10% of terrestrial Earth. Using established ES methodologies, we calculated values (in 2016 USD) for United States National Wildlife Refuge, a region virtually undisturbed by humans, slated future oil and gas drilling. We estimated Refuge is worth about 1957 ...

Forests and rangelands are the most important natural ecosystems which provide many economic benefits to the society due to their biodiversity and ecological functionalities. Dashtenaz wildlife refuge, Sari, is a sylvan region, covering 55 ha of rangeland with abundant diversity, is refuge of an endangered species of deer called Dama mesopotamica. In this study, Contingent Valuation Method (CVM...

Seed dispersal is a fundamental process in plant ecology and is of critical importance for the restoration of tropical communities. The lands of the Cabo Rojo National Wildlife Refuge (CRNWR), formerly under agriculture, were abandoned in the 1970s and colonized mainly by non-native tree species of degraded pastures. Here we described the seed rain under the most common native and non-native tr...

—Once an abundant and conspicuous presence in wetlands across much of north-central North America, Trumpeter Swan ( Cygnus buccinator ) poplulations were decimated in the midto late 1800s by a combination of market hunting, subsistence hunting, and habitat loss. Since then, restoration has focused primarily on reintroduction efforts in which captive-reared birds are released and then monitored....

Introduced mosquito-borne pathogens avian malaria (Plasmodium relictum Grassi and Feletti) and avian pox virus (Avipoxvirus) have been implicated in the past extinctions and declines of Hawaiian avifauna and remain significant obstacles to the recovery and restoration of endemic Hawaiian birds. Effective management of avian disease will require extensive mosquito control efforts that are guided...
