First Recorded Turkey Vulture Nest in Riding Mountain National Park, Manitoba

Bovine tuberculosis in elk (Cervus elaphus manitobensis) near Riding Mountain National Park, Manitoba, from 1992 to 2002.

Factors influencing farmers' concerns regarding bovine tuberculosis in wildlife and livestock around Riding Mountain National Park.

Despite intensive efforts over the last century to eradicate bovine tuberculosis (TB) in North America, several hotspots of infected wildlife and livestock remain, raising concerns that the disease will never be eradicated. The stress and frustration for a farmer caused by having a herd test positive for TB or living in an infected region can be substantial. The goal of this study was to invest...

A new subspecies of Seseli gummiferum (Apiaceae) from Ilgaz Mountain National Park, northern Turkey

A new subspecies Seseli gummiferum Pall. ex Sm. subsp. ilgazense A.Duran, Ö.Çetin & M.Öztürk, subsp. nov. (Apiaceae) is described from Kastamonu province, Turkey. It was collected from the open Pinus sylvestris L. and Abies nordmanniana (Steven) É.Spach. mixed forest in the northern Anatolian region. An endemic apparently confined to the Ilgaz Mountain National Park, the new taxon is closely re...

Estimating chimpanzee population size with nest counts: validating methods in Taï National Park.

Successful conservation and management of wild animals require reliable estimates of their population size. Ape surveys almost always rely on counts of sleeping nests, as the animals occur at low densities and visibility is low in tropical forests. The reliability of standing-crop nest counts and marked-nest counts, the most widely used methods, has not been tested on populations of known size....

Investigating types and sources of organic aerosol in Rocky Mountain National Park using aerosol mass spectrometry

The environmental impacts of atmospheric particles are highlighted in remote areas where visibility and ecosystem health can be degraded by even relatively low particle concentrations. Submicron particle size, composition, and source apportionment were explored at Rocky Mountain National Park using a High-Resolution Time-of-Flight Aerosol Mass Spectrometer. This summer campaign found low averag...
