“…The specimens were sampled using a total of 126 sets of pitfall traps in 21 forest fragments, inserted in pasture matrix, located between the basins of the Jauru and Cabaçal rivers (15.251°S, 058.715°W and 15.561°S, 058.004°W), in the southwestern part of the state of Mato Grosso, Brazil. The phytophysiognomy present in the fragments is described as Submontane Semideciduous Seasonal Forest and is inserted in transition areas between the Amazon and Cerrado biomes, in Mato Grosso (IBGE 2004;Silva Junior et al 2019). In each fragment, six series of traps were installed with five 24 L buckets buried at ground level, arranged every 10 m and interconnected by 80 cm high guide fences.…”

The fossorial snake Apostolepis kikoi Santos et al., 2018 is known only from its type locality, in Chapada dos Guimarães, state of Mato Grosso, Brazil. Here, we present the first records of this species after its description, expanding its distribution to transition areas between the Amazon and Cerrado biomes, in the southwestern portion of Mato Grosso. The new record expands the known distribution of A. kikoi by 297 km west from the type locality. In addition, we provide data on morphological variation by comparing our sample with the type series.

“…Severe droughts cause mortality of flora and fauna species in several biomes, with severe effects on ecosystem function and carbon balance (Choat et al, 2018; Silva Junior et al, 2019). In the case of NEB biomes, the drought occurrence of any intensity impacts rainfall patterns and water recycling (Correia Filho et al, 2019a).…”

The objective of this study was to evaluate the annual standardized precipitation index (SPI) obtained from the DrinC software based on multivariate analysis in the identification of rainfall and drought extremes in the State of Alagoas and its relationship with El Niño-Southern Oscillation. Monthly rainfall data from 1960 to 2016 from National Water Agency were analysed. Annual SPI (SPI-12) has been designed for comparison with ENSO phases via Oceanic Niño Index for 3.4 region and in identifying climate extremes in the State of Alagoas. The principal component analysis and cluster analysis techniques were applied to the rainfall series of SPI-12. Extreme events were identified in both rainy and drought periods according to SPI-12, and were associated with the ENSO phases (El Niño, La Niña, and Neutral). The first four principal components explained 46.68% of the variance. Our findings are crucial for agriculture and civil defence since northeastern Brazil has several areas of risk and social vulnerability.

“…The economy in the state of MS region is based on extensive breeding of beef cattle and agriculture of staple foods, mainly soy (Silva Junior et al, 2018;Silva Junior et al, 2019). Recently, there has been an intensive cultivation of corn and soybeans (economic drivers) and an increase in the mining and the industry sectors.…”

Objectives To analyze the effect of spatially exposure to fire risk on the occurrence of respiratory diseases in the municipalities of the State of Mato Grosso do Sul (MS), Brazil. Methods This was an ecological study of spatial prevalence of hospitalization for respiratory diseases and fire risk using Monte Alegre index. This methodology reduces the risk as precipitation occurs, where the volume of rain (in mm) is considered as danger lane changer. The empirical Bayesian method and a multiple regression spatial response variable were used to model the prevalence of hospitalization for respiratory diseases, and the exposure variable fire hazard. For calibration, the proxies of fire outbreaks and surface ozone concentration, precipitation and humidity were used. Results We observed statistically significant associations between the prevalence of hospitalization for respiratory diseases and the risk of fire. Conclusions fire risks triggering fires are highly related to the prevalence of hospitalizations for respiratory diseases in vulnerable sub populations in the municipalities of the State of Mato Grosso.
