Wildlife population trends in protected areas predicted by national socio-economic metrics and body size
Ensuring that protected areas (PAs) maintain the biodiversity within their boundaries is fundamental in achieving global conservation goals. Despite this objective, wildlife abundance changes in PAs are patchily documented and poorly understood. Here, we use linear mixed effect models to explore correlates of population change in 1,902 populations of birds and mammals from 447 PAs globally. On ...
متن کاملLong-Term Trends and Role of Climate in the Population Dynamics of Eurasian Reindeer
Temperature is increasing in Arctic and sub-Arctic regions at a higher rate than anywhere else in the world. The frequency and nature of precipitation events are also predicted to change in the future. These changes in climate are expected, together with increasing human pressures, to have significant impacts on Arctic and sub-Arctic species and ecosystems. Due to the key role that reindeer pla...

Adaptation of the microflora in the rumen and caecum of the high arctic Svalbard reindeer
The Svalbard reindeer relies on a highly active rumen microbial population of bacteria, fungi and protozoa for the utilization of cellulose and hemicellulose, the major components of growing plants (Rogers and Perkins, 1968). O n Svalbard the availability and quality of food changes during the year, ranging from fresh young forage in summer (July September), to a highly concentrated diet, inclu...
متن کاملNew Ginkgophytes from the Upper Triassic–lower Cretaceous of Spitsbergen and Edgeøya (svalbard, Arctic Norway): the History of Ginkgoales on Svalbard
Premise of research. During the ongoing investigation of Upper Triassic–Lower Cretaceous plant macrofossils from Svalbard, Norway, some ginkgoalean leaf fossils were found from Carnian and Aptian deposits of Spitsbergen and Edgeøya that represent new ginkgophyte species. One new species is described asBaiera aquilonia sp. nov., and one ginkgophyte leaf is assigned to Ginkgoites sp. Along with t...
