Conservationists often advocate for landscape approaches to wildlife management while others argue for physical separation between protected species and human communities, but direct empirical comparisons of these alternatives are scarce. We relate African lion population densities and population trends to contrasting management practices across 42 sites in(More)
The cheetah (Acinonyx jubatus) has been described as a species with low levels of genetic variation. This has been suggested to be the consequence of a demographic bottleneck 10 000-12 000 years ago (ya) and also led to the assumption that only small genetic differences exist between the described subspecies. However, analysing mitochondrial DNA and(More)
Ebola virus (EBOV) is highly pathogenic, with a predisposition to cause outbreaks in human populations accompanied by significant mortality. Owing to the lack of approved therapies, screening programmes of potentially efficacious drugs have been undertaken. One of these studies has demonstrated the possible utility of chloroquine against EBOV using(More)
Our aim was to test the knowledge of clinicians in the Orthopaedic clinic and in the Emergency department of the surface anatomical landmarks that should be examined routinely in the assessment of foot and ankle injuries. A survey of 109 clinicians was conducted. Each participant was asked to palpate six important surface landmarks. Two participants failed(More)
Fecal smears from 112 avian necropsy accessions representing 431 birds were stained with auramine O and examined for Cryptosporidium oocysts by fluorescence microscopy. Stained Cryptosporidium oocysts fluoresced bright yellow-green and were easily differentiated from extraneous material by their uniform small size (approx. 5 micron) and morphology. The(More)
In cell differentiation, a less specialized cell differentiates into a more specialized one, even though all cells in one organism have (almost) the same genome. Epigenetic factors such as histone modifications are known to play a significant role in cell differentiation. We previously introduce cell-type trees to represent the differentiation of cells into(More)
