The 2000 Red List combines animals and plants into a single list containing assessments of more that 18,000 taxa. A large number species has been reassessed there significant increase in the assessments. Documentation on each improved.
Abstract: Nearly half the world's vascular plant species and one‐third of terrestrial vertebrates are endemic to 25 “hotspots” biodiversity, each which has at least 1500 species. None these hotspots have more than their pristine habitat remaining. Historically, they covered 12% land's surface, but today intact covers only 1.4% land. As a result this loss, we expect many hotspot endemics either become extinct or—because much loss is recent—to be threatened with extinction. We used World...
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...
Human pressure threatens many species and ecosystems, so conservation efforts necessarily prioritize saving them. However, should clearly be proactive wherever possible. In this article, we assess the biodiversity value, specifically irreplaceability in terms of endemism, those planet's ecosystems that remain intact. We find 24 wilderness areas, all > 1 million hectares, are 70% intact have human densities less than or equal to five people per km 2 . This covers 44% land but is inhabited...
New remote sensing data on vegetation cover and restoration opportunities bring hope to the Brazilian Atlantic Forest, one of hottest 36 global biodiversity hotspots. Available estimates remaining in biome currently range from 11% 16%. However, our new land-cover map, prepared at highest resolution ever (5 m), reveals a current 28%, or 32 million hectares (Mha) native vegetation. Simultaneously, we found 7.2 Mha degraded riparian areas, which 5.2 least must be restored before 2038 by...
The 1990s may be the last decade during which constructive and creative decisions, activities, investments can made to ensure that many of world's species ecosystems are maintained, examined for their material ecological value, promoted sustainable use support new innovative approaches development. combination maintaining maximum possible biological cultural diversity, greatest scientific endeavor seems most sensible approach toward dealing with dynamic future facing humanity. elements now...
Here we report on the ninth iteration of biennial listing a consensus 25 primate species considered to be among most endangered worldwide and in need conservation measures. The 2016–2018 list world’s primates has five from Africa, six Madagascar, nine Asia, Neotropics.
Abstract The locomotor behavior, of seven sympatric species New World monkeys— Saguinus midas midas, Saimiri sciureus, Pithecia pithecia, Chiropotes satanas chiropotes, Cebus apella apella, Alouatta seniculus , and Ateles paniscus panisus —was studied at the Raleighvallen‐Voltzberg Nature Reserve in Central Surinam. This paper examines way which behavior is related to body size ecological parameters such as forest stratification, type, diet. Locomotor clearly species; with increasing size,...
As the world grows less biologically diverse, it is becoming linguistically and culturally diverse as well. Biologists estimate annual loss of species at 1,000 times or more greater than historic rates, linguists predict that 50-90% world's languages will disappear by end this century. Prior studies indicate similarities in geographic arrangement biological linguistic diversity, although conclusions have often been constrained use data with limited spatial precision. Here we greatly improved...
Conservation efforts are only as sustainable the social and political context within which they take place. The weakening or collapse of sociopolitical frameworks during wartime can lead to habitat destruction erosion conservation policies, but in some cases, may also confer ecological benefits through altered settlement patterns reduced resource exploitation. Over 90% major armed conflicts between 1950 2000 occurred countries containing biodiversity hotspots, more than 80% took place...
The eight monkey species occurring in Surinam were studied the Raleigh-vallen-Voltzberg Nature Reserve along Coppename River. Special emphasis was placed on determining how these divide up available habitat and food resources within a 300-ha study area. Cebus apella is probably most adaptable of monkeys. It found mainly understory lower to middle parts canopy all five forest types (high rain forest, low mountain savanna liane pina swamp forest) area, entered variety edge habitats. Saguinus...
There are currently ca. 317 recognized species of turtles and tortoises in the world. Of those that have been assessed on IUCN Red List, 63% considered threatened, 10% critically endangered, with 42% all known turtle threatened. Without directed strategic conservation planning, a significant portion diversity could be lost over next century. Toward effort, we compiled museum literature occurrence records for world's freshwater to determine their distributions identify priority regions...
Community-based management, ecotourism, and researchers' presence are proposed to prevent lemur extinctions.
In recent decades, many marine populations have experienced major declines in abundance, but we still know little about where management interventions may help protect the highest levels of biodiversity. We used modeled spatial distribution data for nearly 12,500 species to quantify global patterns richness and two measures endemism. By combining these with information on cumulative human impacts, identified priority areas biodiversity is most least impacted by activities, both within...
We present a review and analysis of the conservation status International Union for Conservation Nature (IUCN) threat categories all 360 currently recognized species extant recently extinct turtles tortoises (Order Testudines). Our is based on 2018 IUCN Red List 251 listed species, augmented by provisional assessments Tortoise Freshwater Turtle Specialist Group (TFTSG) 109 unlisted freshwater turtles, as well re-assessments several outdated assessments. Of tortoises, this combined indicates...
Titi monkeys, Callicebus, comprise the most species-rich primate genus-34 species are currently recognised, five of them described since 2005. The lack molecular data for titi monkeys has meant that little is known their phylogenetic relationships and divergence times. To clarify evolutionary history, we assembled a large dataset by sequencing 20 nuclear two mitochondrial loci 15 species, including representatives from all recognised groups. Phylogenetic were inferred using concatenated...
