1. Climate emergency is a significant threat to biodiversity in the 21st century, but species will not be equally affected. In summing up the responses of different species at the local scale, we can assess changes in the species quantity and composition of biotic assemblages. 2. We used more than 420K curated occurrence records of 3,060 plant spe...

Ecological traps occur when species choose to settle in lower-quality habitats, even if this reduces their survival or productivity. This happens in situations of drastic environmental changes, resulting from anthropogenic pressures. In long term, this could mean the extinction of the species. We investigated the dynamics of occurrence and distribu...

The Ladder-tailed Nightjar, Hydropsalis climacocerca, bird with central distribution in the Amazon Basin, was recorded in the state of Maranhão and the middle of the Tocantins River for the first time. An individual adult of the species was recorded in 2016 on a temporary river island downstream from a hydroelectric dam. This record expanded the ar...

A handful ~206 known bumble bee species ( Bombus ) have been transported worldwide and introduced in non-native regions for crop pollination, leading to long-lasting biological invasions. The introductions and invasions of European B. terrestris and, previously, of B. ruderatus in southernSouth America have been associated with sharp population dec...

Background Global shifts in climatic patterns have been recorded over the last decades. Such modifications mainly correspond to increased temperatures and rainfall regime changes, which are becoming more variable and extreme. Methods We aimed to evaluate the impact of future changes in climatic patterns on the distribution of 19 endemic or threate...

The introduction of exotic species into native ecosystems can be a cause for concern when those species are invasive. Invasive species cause ecological problems and have socio‐cultural impacts on human health and the economy; for example, invasive bees may negatively impact their introduced ecosystem by spreading diseases or outcompeting native pol...

The distribution range of many bee species in Asia has been affected by changing climates. Ecological niche models (ENMs) have many applications for predicting the effects of such changes in climate conditions on the future species range. Tetragonula iridipennis Smith, 1854 (Apidae: Meliponini) is a tropical stingless bee distributed in some parts...

Climate change (CC) is expected to negatively impact global biodiversity and ecosystems, resulting in profound ecological impacts and placing complex networks of biological interactions at risk. Despite this worrying scenario, the existing knowledge deficiencies may be overcome with species distribution models (SDMs), providing estimates of the eff...

Ecological traps occur when species choose to settle in lower quality habitats, even if this reduces their survival or productivity. This normally occurs in situations of drastic environmental changes, resulting, for example, from anthropogenic pressures. In the medium and long term, this could mean the extinction of the species. We investigated th...

Climate change and invasive species are critical factors affecting native land snail diversity. In South America, the introduced Giant African Snail (Lissachatina fulica) has spread significantly in recent decades into the habitat of the threatened native giant snails of the genus Megalobu-limus. We applied species distribution modeling (SDM), usin...

One of the main objectives of ecology is to understand how species abundance varies in space. Throughout the distribution of a species, a population is expected to increase its abundance where environmental conditions are most suitable for survival and reproduction. It is possible to evaluate environmental suitability and species distribution with...

Habitat loss and fragmentation in the human-modified landscape affect bee assemblages by reducing the available natural resources. The life history features and adaptations of bees to environmental conditions affect how they perceive and interact with landscape structure. Therefore, it is crucial to quantify the magnitude of the effects of the land...

Introduction Cold-adapted bumblebees are vulnerable to climate change (CC). South American Bombus dahlbomii, the southernmost bumblebee worldwide, has strongly declined since the 1990s and may be particularly susceptible to current and future CC. Aims/methods We asked (1) whether current CC had a role in the observed decline of this species and (2...

Several possible correlations between dioecy and eco-morphological features have been suggested to infer the conditions that would favor this sexual system. Dioecy has been associated either with specialized or generalized pollination systems. The genus Simarouba has six dioecious species that seem to have generalized pollinators. In this study, we...

The leading causes of the worldwide decline in biodiversity are global warming, allied with natural habitat loss and fragmentation. Here, we propose an analysis of the synergistic effects of these two factors in 63 species of Amazonian lizards. We predicted that the high-climatic suitability areas of species would be significantly impacted by diffe...

Climate emergency is a significant threat to biodiversity in the 21st century, but species will not be equally affected. In summing up different species' responses at the local scale, we can assess changes in the species quantity and composition of biotic assemblages. Here we investigated climate change driven variation in species richness and spat...

Although West Indian Cherry (WIC) trees have abundant flowering, specimens of this species have low fructification rates, potentially associated with the dependence of these plants on pollinators for cross-pollination and fruit production. We quantified fructification rates and assessed the market value of pollination services by conducting an expe...

The phantom vampire, Vampyrum spectrum (Chiroptera: Phyllostomidae), is the largest South American flying mammal classified as threatened by the IUCN. Despite the broad distribution of this species across South America, its low population density and the spatial isolation of its populations may compromise its response to the expected climate change...

1. The reproduction of specialised endophagous insects relies on a fine temporal synchronization between the insect and its host plant phenology. 2. Since the spatial distribution and local prevalence of specialised insects depend on both environmental conditions and biotic interactions, in this study, we assessed whether the life cycle of the pred...

Climate change (CC) is an important driver affecting pollination and pollinators. This paper aims to provide an updated potential distribution for Centris nigrescens Lepeletier, 1841, and infer CC effects upon it. We used ten modeling methods to infer the potential distribution of C. nigrescens. We measured the extent of species' suitable area (SSA...

Many species are expected to be at risk from climate change, whereas others may not be threatened because the projected change will occur within their physiological tolerance limits. Particularly, lizards of the genus Uromastyx, known for their narrow climatic and habitat requirements and limited dispersal abilities, might face local or global exti...

Invasive exotic plants may compromise the survival, growth, and reproduction of native species and are among the leading causes of worldwide biodiversity losses. Climate changes—which will affect species distribution—may even amplify the problems caused by invasive species. Here, we used ecological niche models to evaluate the current and future di...

Lanthanomelissa has an uncertain taxonomic history, and was formerly treated either as an independent genus or as a subgenus of Chalepogenus. It is endemic to southern South American grasslands, an endangered and poorly known environment. We aimed to understand the origin of these bees in time and space, the influence of Quaternary climatic fluctua...

Climate change is a matter of worldwide concern with severe predicted impacts on biodiversity. Here, we analysed the potential impacts of current and future climates on aquatic true bugs (Heteroptera) in relation to their distribution patterns and ecological preferences (based on a database generated from existing literature references and field co...

Phenotypic variation in both morphology and symmetry of individuals may appear due to environmental stress caused by land-use changes. Here, we evaluated fluctuating asymmetry (FA) and wing size variations of two orchid bee species, Euglossa ignita Smith, 1874 and Eulaema meriana (Olivier, 1789), comparing 11 wing traits. We sampled the individuals...

The increasing destruction of natural environments worldwide favored more and more alien species' dispersal, distancing people from nature and consequently from native species. We investigated undergrad students' perception about alien and native Brazilian species evaluating classes of the first (freshmen) and last semesters (seniors) of four cours...

We evaluated the role of Quaternary climatic fluctuations on the demographic history and population structure of amphibian species endemic to the ‘campo rupestre’ in the Neotropics, evaluating their distributional shifts, demographic changes, and diversification from the end of Pleistocene to present. We chose two anurans endemic to the high-elevat...

Research on environmental perception is essential for the understanding of individuals’ relations and expectations towards natural environments. Here, we evaluated the perception of high school students on exotic and native species in Brazil. We interviewed 371 students from two high schools located in the state of Goiás, one with and one without a...

The Amazonian and Atlantic Forest share several organisms that are currently isolated but were continuously distributed during the Quaternary period. As both biomes are under different climatic regimes, paleoclimatic events may have modulated species’ niches due to a lack of gene flow and imposing divergent selection pressure. Here, we assessed pat...

Politicians have approved significant changes to the Brazilian Forest Code (Brazilian Law n. 12.651/2012), providing partial pardons for illegal deforestation in 2012. Nonetheless, the New Forest Code (NFC) may cause economic harm, since ecosystem services may be affected, and the productivity of several crops may end up decreasing. Here, we explor...

The Wallacean shortfall—lack of adequate knowledge of a species’ distribution in the geographic space—hinders practical actions towards species conservation, and such severe data deficit is ubiquitous when dealing with insect species. Considering the effects of human activities on Earth, especially in the last 50 years, proper delimitation of speci...

Herein, we present a checklist of birds from the state of Maranhão, northern Brazil. This region is one of the most heterogeneous areas in the country, comprising upland and flooded rainforests, open vegetation cover types, typical from Cerrado and Caatinga, and mangroves along a wide coastal line (an important route for many migratory birds). Clim...

Agricultural expansion as a main human activity has affected pollinator's habitat, causing spatial distribution changes. Meanwhile, pollinators still provide pollination service to improve crop production. However, their spatial response is unclear because of environmental changes. This study sought to estimate spatial distribution of crop producti...

Estimating species’ potential distribution is one of the main objectives of macroecology, especially when sampling biases can affect knowledge on how environmental variables affect species distribution. Ecological niche models estimate species’ environmental niches from different variables and their occurrences. Using the presence‐only data from ei...

The expansion of agricultural and pasture frontier in the Brazilian Cerrado has already led to the loss of 46% of its original vegetation cover since the beginning of the 1980sThis fact caused significant fragmentation of the natural landscape, being the region of MATOPIBA (Maranhão, Tocantins, Piauí and Bahia states) directly related to this expan...

The multiple uses of aquatic ecosystems by humankind and the continuous interference of their activities have contributed to the emergence of potentially toxic cyanobacteria blooms. Here, we firstly created a database of occurrences of cyanobacteria blooms in Brazil through a systematic review of the scientific literature available in online platfo...

Mutualisms are one of the main forces shaping species spatial patterns at all geographic scales. In generalised mutualisms, however, the dependence among partners is highly variable in time and space, and therefore, the effect of diffuse mutualisms on species geographic distributions is unclear. Myrmecochorous seeds in Brazilian semi‐arid vegetatio...

Species invasions are expected to increase continuously with undeniable impact upon native biodiversity, being an important process in relation to the decline of native pollinators. We used species distribution models and multivariate analyses to assess the climatic niche properties of the red dwarf honey bee, Apis florea Fabricius (Apidae: Apini),...

Little is known about the composition of the bee community in the Cerrado-Amazon transition area. Herein, we present the results of a bee survey done within the municipality of Conceição do Araguaia, in the state of Pará. Six fragments were sampled twice (once in the dry season and once in the rainy season) using three methods of collecting: arbore...

Traditional conservation techniques for mapping highly biodiverse areas assume there to be satisfactory knowledge about the geographic distribution of biodiversity. There are, however, large gaps in biological sampling and hence knowledge shortfalls. This problem is even more pronounced in the tropics. Indeed, the use of only a few taxonomic groups...

Bees are normally regarded as social insects that build hives and visit flowers to collect pollen to feed their offspring. However, throughout their evolutionary history, several lineages have lost these characteristics, and have instead, become cleptoparasites, depending on other bee species to raise their offspring. Since cleptoparasites depend o...

Climate change is a key threat to pollination networks and has already caused shifts in the distribution and phenology of many bee species. Predictions based on species distribution models forecast that most bee species will continue to decline as climate change progresses, the few exceptions to this being common, widespread species with large disp...

Nearly all of Earth’s ecosystems are suffering rapid and intense environmental changes, pushing species extinction rates to levels higher than those previously observed in past mass-extinction events. In this context, the ongoing effects of climate change are expected to cause severe impacts on biodiversity in the near- to medium-term future. Yet,...

Land use change impact species richness and functional diversity (FD). In the Brazilian Amazon, we examined the impacts of oil palm plantations on orchid bee (Apidae: Euglossini) species using abundance and FD. We collected male orchid bees in oil palm plantation (PALM), legal reserves (LR), and riparian corridors (APP), and then we used morphologi...

In this research we show that future climate change may put aquatic insects from mountainous regions in Brazil are expected to severely affect the distribution of these species.

• Species distribution modelling (SDM) has been applied to multiple bee species to examine how they may respond to future climate change. Those studies indicate a variety of likely responses to a warming climate. No SDM approaches, however, have been undertaken for arid‐adapted bees, despite their enormous diversity in xeric habitats. • We applied...

The increasing devastation of the Brazilian Atlantic Forest stresses the need to recover areas within this biome, and studies using potential indicator organisms to assess the forest recovery process are important to determine the intensity of human interference during this process. We aimed to evaluate the richness and abundance of ant genera in f...

Although Brazil is a megadiverse country and thus a conservation priority, no study has yet quantified conservation gaps in the Brazilian protected areas (PAs) using extensive empirical data. Here, we evaluate the degree of biodiversity protection and knowledge within all the Brazilian PAs through a gap analysis of vertebrate, arthropod and angiosp...

The Eurasian bumble bee Bombus terrestris Linnaeus has been used commercially for pollination of a large number of crop species worldwide. This species has become invasive in several countries where it has escaped into natural environments. This species has become naturalized in many zones of Chile and southern Argentina, and may potentially invade...

Orchid bees (Apidae, Euglossini) are important pollinators in the Amazon forest. In eastern Brazilian Amazon, secondary forest and pastures are being replaced by oil palm plantations. Here, we tested the role of forest reserves and riparian corridors in maintaining orchid bees. We sampled bees in three different soil-type uses, comparing richness,...

Knowledge of spatiotemporal distribution of biodiversity is still very incomplete in the tropics. This is one of the major problems preventing the assessment and effectiveness of conservation actions. Mega-diverse tropical regions are being exposed to fast and profound environmental changes, and the amount of resources available to describe the dis...

Landscape structure is an important determinant of biological fluxes and species composition, but species do not respond equally to landscape features or spatial extents. Evaluating “multi-scale” responses of species to landscape structure is an important framework to be considered, allowing insights about habitat requirements for different groups....

The historical contingencies of biological invasions may have important consequences for final invasion outcomes. Here, we characterize the variations in the realized niche during the invasions of the bull-headed dung beetle Onthophagus taurus (Coleoptera: Scarabaeidae) from its native Mediterranean range following accidental (Eastern North America...

Aim The knowledge of biodiversity facets such as species composition, distribution and ecological niche is fundamental for the construction of biogeographic hypotheses and conservation strategies. However, the knowledge on these facets is affected by major shortfalls, which are even more pronounced in the tropics. This study aims to evaluate the ef...

Despite their relevance for the maintenance of terrestrial ecosystems, important aspects such as the biology and distribution range remain unknown for most species of bees that occur in the Neotropical region. This makes the monitoring of pollinators and the establishment of conservation policies difficult. In this paper, we provide information on...

Data shortfalls on species distribution affect species differently, but it is frequent among insects. Species distribution models (SDMs) are important tools to fill biogeographic deficits and provide support for practical conservation actions, particularly for cryptic or hard to survey species. We employed SDMs to evaluate one such species, the lon...

Recent studies suggest an alarming decline in pollinators across many regions of the world due to multiple factors. One potential factor is climate change, which poses both direct and indirect threats to pollinator popula- tions. To help ameliorate the impact of declining populations on the func- tion of ecological and agricultural systems, there i...
