Article
Full-text available
Invertebrates constitute the majority of animal species and are critical for ecosystem functioning and services. Nonetheless, global invertebrate biodiversity patterns and their congruences with vertebrates remain largely unknown. We resolve the first high-resolution (~20-km) global diversity map for a major invertebrate clade, ants, using biodiver...
Article
Full-text available
Climate and land-use changes are expected to negatively affect many species and ecological processes, leading to biodiversity loss. However, some species can adapt to these changes. Wide-ranging species are expected to be less impacted by such changes, but they can occur in different domains with contrasting environmental conditions , resulting in...
Article
Full-text available
India hosts multiple global biodiversity hotspots while being one of the most populous countries in the world. Here, we examine how well India has protected its avifauna, based on the fraction of their ranges falling within “protected areas.” India has protected 5% of its land this way. The issue is whether India has done better than expected in pr...
Article
Full-text available
The species‐range size distribution is a product of speciation, transformation of range‐sizes, and extinction. Previous empirical studies showed that it has a left‐skewed lognormal‐like distribution. We developed a new mathematical framework to study species‐range‐size distributions, one in which allopatric speciation, transformation of range size,...
Article
Full-text available
Significance Landslides are triggered more often by human-induced changes, such as deforestation, infrastructure building, and increasing precipitation extremes, because of climate change. The huge economic and societal loss calls for a more cost-effective way to reduce risks and ensure sustainable development. Land-cover and land-use changes not o...
Article
Full-text available
International and national initiatives aim to conserve at least 30% of lands and waters by 2030. To safeguard biodiversity, conservation actions must be distributed in places that represent ecosystem and species diversity. Various methods of prioritizing sites for conservation have been used in local and global assessments. However, the performance...
Article
Full-text available
Accurate maps of species ranges are essential to inform conservation, but time-consuming to produce and update. Given the pace of change of knowledge about species distributions and shifts in ranges under climate change and land use, a need exists for timely mapping approaches that enable batch processing employing widely available data. We develop...
Chapter
Full-text available
Amazon aquatic ecosystems are being destroyed and the threats to their integrity are projected to grow in number and intensity. In this chaper we review a number of these threats. Hydroelectric dams (n=307 existing or under construction) have changed almost every aspect of Amazon aquatic ecosystems, and many more dams are planned (n=239), posing th...
Technical Report
Full-text available
Deforestation, the complete removal of an area’s forest cover; and forest degradation, the significant loss of forest structure, functions, and processes; are the result of the interaction between various direct drivers, often operating in tandem. By 2018, the Amazon biome had lost approximately 870,000 km2 of its original forest cover, mainly due...
Chapter
Full-text available
Scientists have not been able to estimate, to the nearest order of magnitude, the number of species in the Amazon. Although the Amazon includes one of the largest forests in the world, it is also one of the least known biologically. Documenting its biodiversity is challenging because of its immense size, heterogeneity, and limited access. Based on...
Chapter
Full-text available
This chapter discusses the main drivers of deforestation and forest degradation in the Amazon, particularly agricultural expansion, road construction, mining, oil and gas development, forest fires, edge effects, logging, and hunting. It also examines these activities’ impacts and synergies between them.
Chapter
Full-text available
This Report provides a comprehensive, objective, open, transparent, systematic, and rigorous scientific assessment of the state of the Amazon’s ecosystems, current trends, and their implications for the long-term well-being of the region, as well as opportunities and policy relevant options for conservation and sustainable development.

The Caucasus region is a meeting point for culture and nature, lying at the nexus of Europe, the Middle East, Central Asia, and Africa, and identified as one of 36 global biodiversity hotspots. The Republic of Georgia, the center of the Caucasus biodiversity hotspot, encompasses a geographically diverse landscape inhabited by a remarkable, endemic,...
Article
Full-text available
A growing number of companies have announced zero-deforestation commitments (ZDCs) to eliminate commodities produced at the expense of forests from their supply chains. Translating these aspirational goals into forest conservation requires forest mapping and monitoring (M&M) systems that are technically adequate and therefore credible, salient so t...

Full-text available
With a wide distribution across eastern South America, the Brazilian Atlantic Forest is a mosaic of lowland and montane vegetation types, such as evergreen forest, semideciduous and deciduous forest, mixed forest (e.g., Araucaria), mangroves, and restingas. It has long been recognized as having one of the most diversified biotas on the planet, with...
Chapter
Full-text available
The Atlantic Forest is a heterogeneous and complex vegetation mosaic caused by variety of climatic, geomorphological, and edaphic conditions. It has long been known that the Atlantic Forest has one of the most diversified biotas on the planet, presenting high levels of endemism. Here, we update the knowledge regarding terrestrial vertebrates occurr...
Article
Full-text available
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropica...
Article
Full-text available
We compare the numbers of vascular plant species in the three major tropical areas. The Afrotropical Region (Africa south of the Sahara Desert plus Madagascar), roughly equal in size to the Latin American Region (Mexico southward), has only 56,451 recorded species (about 170 being added annually), as compared with 118,308 recorded species (about 75...
Article
Full-text available
Learning from the rapidly growing body of scientific articles is constrained by human bandwidth. Existing methods in machine learning have been developed to extract knowledge from human language and may automate this process. Here, we apply sentiment analysis, a type of natural language processing, to facilitate a literature review in reintroductio...
Article
Full-text available
Energy development – as manifested by the proliferation of hydroelectric dams and increased oil and gas exploration – is a driver of change in Amazonian ecosystems. However, prevailing approaches to Amazonian ecosystem conservation that focus on terrestrial protected areas and Indigenous territories do not offer sufficient insurance against the ris...
Article
Full-text available
Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across...
Article
Full-text available
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species includes assessment of extinction risk for 98 512 species, plus documentation of their range, habitat, elevation, and other factors. These range, habitat and elevation data can be matched with terrestrial land cover and elevation datasets to map the species' ar...

Article
Full-text available
Investigating the influence of coastal development on marine environments is a priority to maintain healthy seas. Cetaceans are top predators, keystone and umbrella species and thus are good candidate models to evaluate the extent of anthropogenic impacts on coastal habitats. We employed a generalized linear model with spatial eigenvector mapping (...
Article

Further expansion of agriculture in the tropics is likely to accelerate the loss of biodiversity. One crop of concern to conservation is African oil palm (Elaeis guineensis). We examined recent deforestation associated with oil palm in the Peruvian Amazon within the context of the region's other crops. We found more area under oil palm cultivation...
Article
Full-text available
It is theoretically possible to protect large fractions of species in relatively small regions. For plants, 85% of species occur entirely within just over a third of the Earth’s land surface, carefully optimized to maximize the species captured. Well-known vertebrate taxa show similar patterns. Protecting half of Earth might not be necessary, but w...
Article
Full-text available
The relationship between levels of dominance and species richness is highly contentious, especially in ant communities. The dominance‐impoverishment rule states that high levels of dominance only occur in species‐poor communities, but there appear to be many cases of high levels of dominance in highly diverse communities. The extent to which domina...

Full-text available
Andes-to-Amazon river connectivity controls numerous natural and human systems in the greater Amazon. However, it is being rapidly altered by a wave of new hydropower development, the impacts of which have been previously underestimated. We document 142 dams existing or under construction and 160 proposed dams for rivers draining the Andean headwat...

South America holds 30% of the world's avifauna, with the Atlantic Forest representing one of the richest region of the Neotropics. Here we compiled a dataset on Brazilian Atlantic Forest bird occurrence (150,423) and abundance samples (N=832 bird species; 33,119) using multiple methods, including qualitative surveys, mist-nets, point counts, and l...
Article
Full-text available
Our understanding of mammal ecology has always been hindered by the difficulties of observing species in closed tropical forests. Camera trapping has become a major advance for monitoring terrestrial mammals in biodiversity rich ecosystems. Here we compiled one of the largest datasets of inventories of terrestrial mammal communities for the Neotrop...
Article
Full-text available
The Eastern Arc Mountains of Tanzania and the Atlantic Forest of Brazil are two of the most fragmented biodiversity hotspots. Species-area relationships predict that their habitat fragments will experience a substantial loss of species. Most of these extinctions will occur over an extended time, and therefore, reconnecting fragments could prevent s...

Algunos de los que leen este libro sin duda se preguntarán en algún momento sobre la verdadera importancia de la investigación en la Estación de Biodiversidad Tiputini (EBT). Al final, ¿para qué tanto esfuerzo a favor de una estación científica tan pequeña? ¿Cómo podría un país del tamaño del Ecuador competir en el campo científico frente a países...
Article
Full-text available
Small forest fragments may play a major role in fragmented areas, but there is scarce empirical data to test this hypothesis. To understand in which context birds can use small Atlantic Forest fragments, we tested the presence of 11 bird species in 30 small fragments (4–10 ha), in a range of matrices (eucalyptus-pasture), and in different landscape...
Article
Full-text available
What forces structure ecological assemblages? A key limitation to general insights about assemblage structure is the availability of data that are collected at a small spatial grain (local assemblages) and a large spatial extent (global coverage). Here, we present published and unpublished data from 51,388 ant abundance and occurrence records of mo...
Article
Full-text available
Current systems of conservation reserves may be insufficient to sustain biodiversity in the face of climate change and habitat losses. Faced with these pressures, calls have been made to protect the Earth's remaining wildlands and complete the system of protected areas by establishing conservation reserves that (i) better represent ecosystems; (ii)...
Article
Full-text available
The IUCN (International Union for Conservation of Nature) Red List classifies species according to their risk of extinction, informing global to local conservation decisions. Unfortunately, important geospatial data do not explicitly or efficiently enter this process. Rapid growth in the availability of remotely sensed observations provides fine-sc...
Article
Full-text available
The IUCN Red List has assessed the global distributions of the majority of the world's amphibians, birds and mammals. Yet these assessments lack explicit reference to widely available, remotely-sensed data that can sensibly inform a species' risk of extinction. Our first goal is to add additional quantitative data to the existing standardised proce...

Full-text available
Palm oil is the most widely traded vegetable oil globally, with demand projected to increase substantially in the future. Almost all oil palm grows in areas that were once tropical moist forests, some of them quite recently. The conversion to date, and future expansion, threatens biodiversity and increases greenhouse gas emissions. Today, consumer...
