Lutzomyia longipalpis, 15 other species of the genus Lutzomyia, and one species of Brumptomyia were collected in an endemic focus of cutaneous leishmaniasis in a river canyon 450 m above sea-level, in Rio Claro, Antioquia, Colombia. The presence of Lu. longipalpis is associated with the destruction of the primary forest and the development of new farmland and rural settlement in this region. Th...

Beginning with an outline of uncertainties about the number of species on Earth today, this paper addresses likely causes and consequences of the manifest acceleration in extinction rates over the past few centuries. The ultimate causes are habitat destruction, alien introductions, overexploitation and climate change. Increases in human numbers and per capita impacts underlie all of these. Agai...

According to Article 4(4) of Directive 92/43/EEC, “once a site of Community importance has been adopted in accordance with the procedure laid down in paragraph 2, the Member State concerned shall designate that site as a special area of conservation as soon as possible and within six years at most, establishing priorities in the light of the importance of the sites for the maintenance or restor...

Summary This paper reports a further discovery of new endemic threatened species to science in the context botanical surveys lowland coastal forests Mount Cameroon Cross River-Sanaga interval west-central Africa. These studies now focus on and conservation through Tropical Important Plant Areas programme. New continue be discovered from Mt Cameroon. Most these are rare, highly localised, by hab...

Oil palm is expected to make a significant contribution to the predicted two-fold increase in demand for vegetable oils over the next forty years. Given the current expansion of the oil palm, there is much debate on the sustainability of oil palm due to deforestation and habitat destruction that is occurring in Indonesia, raising serious concerns regarding the sustainability of this cultivation...

Australia is rich in orchid flora with over 1000 native species currently recorded. A significant proportion of Australia’s terrestrial orchids are critically endangered, endangered or threatened. Threats to many orchid species include habitat destruction, degradation and fragmentation from increased urbanisation, overgrazing, altered fire regimes and unfortunately, excessive collecting by orch...

Spermophilus xanthoprymnus (Bennett, 1835), the Asia Minor ground squirrel, is a group-living, diurnal, obligately hibernating marmotine squirrel. It inhabits the steppes and alpine meadows throughout central lowland and eastern highland Anatolia and adjacent Armenia and northwestern Iran. Its preferred elevation appears to range from about 800 to 2,900 m. The species displays sexual dimorphism...

Intense human pressure and global warming have caused habitat destruction in these areas increased the number of endangered species. These species are endemic to Nuratau ridge under high pressure. We found four populations both ridge. For each population we measured plant density determined maturity ontogenetic spectrum. also described community where grew. At all sites was low, with most being...

The study was carried out to compare the biodiversity parameters of insect species in natural and un-natural habitats Gölcük Nature Park (Isparta Province) between 2018 2019. Two two unnatural (impact tourism) were selected realize mentioned aim. Totally 40 pitfall traps (10 for each habitat) set up sample Coleoptera species. Species richness found higher than ones. Diversity index (both Shanno...
