The populations of farmland birds in Europe declined markedly during the last quarter 20th century, representing a severe threat to biodiversity. Here, we assess whether declines and ranges across reflect differences agricultural intensity, which arise largely through political history. Population range changes were modelled terms number indices intensity. contractions significantly greater countries with more intensive agriculture, higher European Union (EU) than former communist countries....
World governments have committed to halting human-induced extinctions and safeguarding important sites for biodiversity by 2020, but the financial costs of meeting these targets are largely unknown. We estimate cost reducing extinction risk all globally threatened bird species (by ≥1 International Union Conservation Nature Red List category) be U.S. $0.875 $1.23 billion annually over next decade, which 12% is currently funded. Incorporating nonavian increases this total $3.41 $4.76 annually....
The growing demand for biofuels is promoting the expansion of a number agricultural commodities, including oil palm (Elaeis guineensis). Oil-palm plantations cover over 13 million ha, primarily in Southeast Asia, where they have directly or indirectly replaced tropical rainforest. We explored impact spread oil-palm on greenhouse gas emission and biodiversity. assessed changes carbon stocks with changing land use compared this amount fossil-fuel avoided through its replacement by biofuel...
Abstract: The monitoring of trends in the status species or habitats is routine developed countries, where it funded by state large nongovernmental organizations and often involves numbers skilled amateur volunteers. Far less natural resources takes place developing agencies have small budgets, there are fewer professionals amateurs, socioeconomic conditions prevent development a culture volunteerism. resulting lack knowledge about presents serious challenge for detecting, understanding,...
Offspring sex ratios in wild bird populations, and the extent to which they vary from equality expected by random genotypic determination, have received much recent attention. Adult (ASRs) birds, on other hand, remain very poorly described, many of questions about them posed Ernst Mayr 1939 unanswered. This review assesses population‐level ratio patterns with an emphasis ASR. A quantitative assessment over 200 published estimates ASR, covering species a wide range taxa, regions habitats,...
Summary The spread and intensification of agriculture are recognized as two the most important global threats to wildlife. There clear links between agricultural change declines in biodiversity across a wide range systems, convincing evidence that reversing these changes leads recovery wildlife populations. Nearly 4 billion euros now paid annually through agri‐environment schemes (AES) farmers Europe North America make environmental improvements their land. Where appropriately designed...
Expansion of cropland in tropical countries is one the principal causes biodiversity loss, and threatens to undermine progress towards meeting Aichi Biodiversity Targets. To understand this threat better, we analysed data on crop distribution expansion 128 countries, assessed changes area main crops mapped overlaps between conservation priorities cultivation potential. Rice was single grown over largest area, especially forest biomes. Cropland expanded by c. 48,000 km2 per year from...
Abstract We provide a global, spatially explicit characterization of 47 terrestrial habitat types, as defined in the International Union for Conservation Nature (IUCN) classification scheme, which is widely used ecological analyses, including quantifying species’ Area Habitat. produced this novel map year 2015 by creating global decision tree that intersects best currently available data on land cover, climate and use. independently validated using occurrence 828 species vertebrates (35152...
Malignant tumors of the skull base are rare. Therefore, no single center treats enough patients to accumulate significant numbers for meaningful analysis outcomes after craniofacial surgery (CFS). The current report was based on a large cohort that analyzed retrospectively by an International Collaborative Study Group.One thousand three hundred seven who underwent CFS in 17 institutions were analyzable outcome. median age 54 years (range, 1-98 years). Definitive treatment prior had been...
Background. Advances in imaging, surgical technique, and perioperative care have made craniofacial resection (CFR) an effective safe option for treating malignant tumors involving the skull base. The procedure does, however, complications. Because of relative rarity these tumors, most existing data on postoperative complications come from individual reports relatively small series patients. This international collaborative report examines a large cohort patients accumulated multiple...
Conservation of the planet's biodiversity will depend on international policy intervention, yet evidence-based assessment success such intervention is lacking. Poor understanding effectiveness instruments exposes them to criticism or abandonment and reduces opportunities improve them. Comparative analyses population trends provide strong evidence for a positive impact one instrument, European Union's Birds Directive, we identify associations between rate provision certain conservation...
This paper describes changes in bird communities following the conversion of lowland forest to commercial oil palm and rubber plantations. Conversion plantations resulted a reduction species richness at least 60%, with insectivores frugivores suffering greater losses than more omnivorous species. Of 128 recorded across all habitats, 84% were forest, 60% only that habitat. 16 Globally Threatened or Near-Threatened study, 15 forest. Species occurring significantly widespread Thailand forests...
Background. Malignant tumors of the superior sinonasal vault are rare, and, because this and varied histologic findings, most outcomes data reflect experience small patient cohorts. This International Collaborative study examines a large cohort patients accumulated from multiple institutions experienced in craniofacial surgery, with aim reporting benchmark figures for identifying patient-related tumor-related predictors prognosis after resection (CFR). Methods. Three hundred thirty-four 17...
Abstract Aim Long‐term monitoring of biodiversity is necessary to identify population declines and develop conservation management. Because long‐term labour‐intensive, resources implement robust programmes are lacking in many countries. The increasing availability citizen science data online public databases can potentially fill gaps structured programmes, but only if trends estimated from unstructured match those programmes. We therefore aimed assess the correlation between data. Location...
Summary Important Bird and Biodiversity Areas (IBAs) are sites identified as being globally important for the conservation of bird populations on basis an internationally agreed set criteria. We present first review development spread IBA concept since it was launched by BirdLife International (then ICBP) in 1979 examine some characteristics resulting inventory. Over 13,000 global regional IBAs have so far been documented terrestrial, freshwater marine ecosystems almost all world’s countries...
Limited resources are available to address the world's growing environmental problems, requiring conservationists identify priority sites for action. Using new distribution maps all of forest-dependent birds (60.6% bird species), we quantify contribution remaining forest conserving global avian biodiversity. For each partly or wholly forested 5-km cells, estimated an impact score its species occur within it, and so is proportional on conservation status were it contains lost. The scores was...
