We study the well-known lion-and-man game in which a lion (the pursuer) tries to capture a man (the evader). The players have equal speeds and they can observe each other at all times. While the game is well-studied in two dimensional domains such as polygons, very little is known about its properties in higher dimensions. In this paper, we study the lion and man game on the surface of convex t...

The lion Panthera leo is one of the world's most charismatic carnivores and is one of Africa's key predators. Here, we used a large dataset from 357 lions comprehending 1.13 megabases of sequence data and genotypes from 22 microsatellite loci to characterize its recent evolutionary history. Patterns of molecular genetic variation in multiple maternal (mtDNA), paternal (Y-chromosome), and bipare...

The evolutionary history of a species is key for understanding the taxonomy and for the design of effective management strategies for species conservation. The knowledge about the phylogenetic position of the lion (Panthera leo) in West/Central Africa is largely based on mitochondrial markers. Previous studies using mtDNA only have shown this region to hold a distinct evolutionary lineage. In a...

The lion Panthera leo is Critically Endangered in West Africa and is known to occupy only four protected areas within the region. The largest population persists in the trans-boundary W-Arly-Pendjari (WAP) ecosystem, in the border region of Benin, Burkina Faso, and Niger. WAP harbors an estimated 350 individuals, or 90% ofWest Africa’s lions. We modeled lion occupancy across WAP using systemati...

Pleistocene skinning and exploitation of carnivore furs have been previously inferred from archaeological evidence. Nevertheless, the evidence of skinning and fur processing tends to be weak and the interpretations are not strongly sustained by the archaeological record. In the present paper, we analyze unique evidence of patterned anthropic modification and skeletal representation of fossil re...

Lion (Panthera leo) populations are in decline throughout most of Africa. The problem is particularly acute in southern Kenya, where Maasai pastoralists have been spearing and poisoning lions at a rate that will ensure near term local extinction. We investigated 2 approaches for improving local tolerance of lions: compensation payments for livestock lost to predators and Lion Guardians, which d...

Here, we present a review of the dataset resulting from the 11-years follow-up of Trypanosoma cruzi infection in free-ranging populations of Leontopithecus rosalia (golden lion tamarin) and Leontopithecus chrysomelas (golden-headed lion tamarin) from distinct forest fragments in Atlantic Coastal Rainforest. Additionally, we present new data regarding T. cruzi infection of small mammals (rodents...

A adult female California sea lion (Zalophus californianus) was observed ashore in Marin County, Calif, on January 1, 2010. Assessment of the sea lion the next day indicated it was lethargic and had multiple minor skin wounds. The sea lion was captured and transported to the Marine Mammal Center in Sausalito, Calif, for a health assessment and medical care. Physical examination of the sea lion ...

The African lion is in decline across its range, and consumptive utilisation and trade of their body parts and skins has been postulated as a cause for concern. We undertook a pan-African questionnaire and literature survey to document informed opinion and evidence for the occurrence of domestic and international trade and consumption in African lion body parts across current and former range s...

When an indefinite newly introduces or reintroduces an accessible referent into the discourse, it is called specific. Thus, in (1a), it can be coreferential with a lion in the previous sentence, which indicates a particular lion in the relevant situation. By contrast, a nonspecific indefinite has no specific referent at all, as is illustrated in (1b), where a lion can be any lion. In that case,...
