Knowledge of mammalian diversity is still surprisingly disparate, both regionally and taxonomically. Here, we present a comprehensive assessment the conservation status distribution world's mammals. Data, compiled by 1700+ experts, cover all 5487 species, including marine Global macroecological patterns are very different for land species but suggest common mechanisms driving endemism across systems. Compared with threat levels higher among mammals, driven processes (accidental mortality...
Assessing Biodiversity Declines Understanding human impact on biodiversity depends sound quantitative projection. Pereira et al. (p. 1496 , published online 26 October) review scenarios that have been developed for four main areas of concern: species extinctions, abundances and community structure, habitat loss degradation, shifts in the distribution biomes. are projected whole 21st century all scenarios, but with a wide range variation. Hoffmann 1503 draw results five decades' worth data...
Significance Illegal harvest for commercial trade has recently surged to become a major threat some of the world’s most endangered and charismatic species. Unfortunately, cryptic nature illegal killing makes estimation rates impacts difficult. Applying model based on field census carcasses, our knowledge we provide first detailed assessment African elephant at population, regional, continental scales. in ivory surged, coinciding with increases seizures black market prices. As result, species...
Abstract Poaching is contributing to rapid declines in elephant populations across Africa. Following high-profile changes the political environment, overall number of illegally killed elephants Africa seems be falling, but evaluate potential conservation interventions we must understand processes driving poaching rates at local and global scales. Here show that annual 53 sites strongly correlate with proxies ivory demand main Chinese markets, whereas between-country between-site variation...
Elephant poaching and the ivory trade remain high on agenda at meetings of Convention International Trade in Endangered Species Wild Fauna Flora (CITES). Well-informed debates require robust estimates trends, spatial distribution poaching, drivers poaching. We present an analysis trends indicator elephant all species. The site-based monitoring system known as Monitoring Illegal Killing Elephants (MIKE), set up by 10th Conference Parties CITES 1997, produces carcass encounter data reported...
Abstract The international legal trade in wildlife can provide economic and other benefits, but when unsustainable be a driver of population declines. This impact is magnified by the additional burden illegal trade, yet how it covaries with remains little explored. We combined law‐enforcement time‐series seizures goods imported into United States (US) European Union (EU) data on reported to evaluate evidence for any relationships. Our analysis examined 28 US 20 EU products derived from...
This paper presents an analysis of changes in elephant population estimates selected from the two most recent reports African Elephant Database (AED). Sites for were restricted to surveyed areas which successive had been made using comparable methods. The resulting selection consisted surveys conducted eastern and southern Africa between 1994 2002, together cover a large percentage total are available these regions. results suggest significant overall increase (p < 0.0002) sites combined....
Abstract The objective of this paper is to provide an estimate the elasticity elephant poaching with respect prices. Ivory being a storable commodity subjects its price Hotelling’s no-arbitrage condition, hence allowing identification supply curve. gold, one many commodities used as stores value, thus instrument for ivory illegal found be inelastic 0.4, changes in consumer prices passing-through faced by producers at rate close unity. Estimations based on number alternative estimation...
Performance and adaptive management systems were introduced in all protected areas Ghana to stop the decline wildlife further loss of biodiversity. The competitive system resulted an increase relative abundance at seven sites where had been operation for 4 years (2004–2008). We examined relationships between wildlife-based tourism park management, key factors that may influence tourism. First, we scrutinized relationship illegal activity numbers visitors, wildlife, road network. Poaching...
Human breakpoint cluster region (bcr) gene product is a member of group GTPase-activating proteins that act exclusively on members the Ras-related Rho subfamily. A complementary DNA was isolated from Caenorhabditis elegans encoded polypeptide 1438 amino acid residues, CeGAP, which contains domain with sequence similarity to COOH-terminal segment (GTPase-activating protein region) Bcr and other known It also pleckstrin homology motif, present in many signaling including nucleotide exchange...
Abstract The international legal trade in wildlife can provide economic and other benefits, but when unsustainable be a driver of population declines. This impact is enhanced by the additional burden illegal trade. We combined law-enforcement time-series seizures goods imported into United States (US) European Union (EU) with data on reported to evaluate evidence for any relationships. Our analysis examined 28 20 taxon-products high volume frequency seizures. On average, added 28% 9% US EU...
