The need for basic information on tropical crop pollinators remains a key priority. Here, we used a dataset on Brazilian bee-crop interactions to determine important bee species for crop pollination and discuss their management in Brazilian croplands. We developed an analytical approach to select key bee species and genera from datasets based on di...

Crop suitability evaluation plays an essential role on strategic planning for agricultural activities. Due to future climate change scenarios, there is a possibility that areas previously suitable for certain crops may become inadequate. The rules-based method used to evaluate crop suitability depends on costly field experiments. This paper propose...

Anthropogenic-induced climate change has already altered the conditions to which species have adapted locally, and consequently, shifts of occurrence areas have been previously reported (Chen et al. 2011). Anticipating the results of climate change is urgent, and using these results efficiently to guide decision-making can help to build strategies...

Anthropogenic climate change is one of the main current threats to biodiversity, and it has been linked to species decline. Bats deserve attention because they occupy different trophic niches and perform different functions in nature, acting as flower pollinators (nectarivores), seed dispersers (frugivores), and pest controllers (insectivores). The...

Escherichia coli is an important microorganism in the gastrointestinal tract of warm-blooded animals. Commensal populations of E. coli consist of stable genetic isolates, which means that each individual has only one phylogenetic group (phylogroup). We evaluated the frequency of human commensal E. coli phylogroups from 116 people and observed that...

O Nordeste do Brasil apresenta uma vasta região semiárida conhecida como “Caatinga” que já foi predominantemente coberta por Florestas Tropicais Secas. As espécies animais e vegetais nessa área podem ter que suportar longos períodos de estresse hídrico, já que o período seco é bem prolongado. As duras condições climáticas associadas a práticas inad...

Animal pollination can impact food security since many crops depend on pollinators to produce fruits and seeds. However, the effects of projected climate change on crop pollinators and therefore on crop production are still unclear, especially for wild pollinators and aggregate community responses. Using species distributional modeling, we assessed...
Data
Pollinator species of each agricultural crop analyzed. Each crop presents different dependence for animal pollination (Giannini et al. 2015b). Pollinator species used here were previously considered as being effective, occasional or potential pollinators of each analyzed crop (Giannini et al. 2015a). (DOCX)
Data
Data sources retrieved from speciesLink and GBIF website. (DOCX)
Data
Shifts on pollinators’ occurrence probability for all crops analyzed (13 crops) considering A) the overall average of decrease in probability; B) the number and percentage of municipalities that will potentially face decrease or increase on pollinators’ occurrence probability (total number of municipalities analyzed equals to 4975). (DOCX)
Data
Municipalities that will potentially face the highest negative shift on pollinators’ occurrence probability and that present the highest percentage of gross domestic product (GDP) associated to the analyzed crops. We considered 25% of the highest values of negative shift on pollinators and, from those, the 15 municipalities that present the highest...
