Ants are ecologically dominant and have been used as valuable bio-indicators of environmental change or disturbance being used in monitoring inventories.  However, the majority of inventories has concentrated in ground-dwelling ant fauna disregarding the arboreal fauna. This paper aimed to list the ant species collected both on the ground and in the vegetation of the Parque Estadual do Cristalino, an important protected site in the center of the southern Amazon. Moreover, we compared the composition of the ground dwelling and vegetation foraging ants. Was sampled 203 species distributed among 23 genera and eight subfamilies, wherein 35 species had not yet been reported in the literature for Mato Grosso State. As expected, the abundance and richness of ants was higher on the ground than in the understory. Also, the ant assemblages composition was different between these habitats (with only 20% occurring in both). It indicate that complementary methods which include arboreal and terrestrial ants are indicated for efficient inventory. This study provides an inventory of the arboreal and ground ant fauna contributing to the knowledge and conservation of ant fauna of the Amazonian.

Abstract The role of different bait types and trap installation heights for an accurate trapping of flower chafer beetles (Coleoptera: Cetoniidae) is still poorly understand worldwide, especially in the Neotropical region. Therefore, in this study, we evaluated how the type of bait and trap installation height can influence flower chafer beetle sampling in the Amazon rainforest. For this, we sampled flower chafer beetles monthly from June to December 2019 in five Amazon forest fragments, in Juína, Mato Grosso, Brazil. In each collecting fragment, we installed aerial traps at different heights (i.e., 1.5, 4.5, 7.5, and 10.5 m above ground) and randomly baited with 300 ml of each of the following bait types: banana + sugarcane juice mixture; pineapple + sugarcane juice mixture; beer; or red wine. We collected 412 individuals belonging to 12 species of Cetoniidae beetles. Traps baited with pineapple + sugarcane juice mixture captured greater abundance and species richness of flower chafer beetles. Moreover, traps at 4.5, 7.5, and 10.5 m caught a similar number of individuals and species, and significantly more than traps at 1.5 m. Thus, our results provide evidence that for an accurate sampling of flower chafer beetle assemblages in tropical forests, traps baited preferably with a ripe fruit (e.g., pineapple) and sugarcane juice mixture should are installed at least 4.5 m above ground.

Vegetation Mosaic

We examined how vegetation mosaic influences distribution of the edaphic ant (Formicidae) community in the northern part of the Pantanal in Cáceres, State of Mato Grosso, Brazil. Plant formations (hereafter habitats) that characterize this area include several savanna types, such as: Cerrado sensu stricto, Cerradão, Semi-deciduous forest, Termite savanna, Open fields and Cerrado field/carandazal. Pitfall traps were placed in ten 250 m transects each one separated by 1 km, within an area of 2 x 5 km (following RAPELD methodology). Five traps at intervals of 50 m were placed along each transect, in September and December 2008. Forty-four ant species were collected. leaf litter predicted ant presence and influenced species occurrence in the different habitats. Pantanal habitats are very different structurally from one to another, which has have resulted in areas with very specific ant assemblages. The understanding of the antcommunity structure in these areas is fundamental to floodplain management.

Thyroptera Tricolor

We present new records for the disk-winged bats Thyroptera tricolor and T. devivoi in central and northern Brazil. Records of T. tricolor are from Aripuanã, Usina Hidrelétrica (UHE) Colíder (both in the northern Mato Grosso state) and Santana do Araguaia (southern Pará state). New records of T. devivoi are from a Cerrado area in the Rio Manso, Rio Quilombo (both in Mato Grosso state) and from an Amazon rainforest area at Juruti (Pará state). The records of Thyroptera devivoi for Pará and Mato Grosso are the first ones for these states and the records from the latter are based on two specimens previously identified as T. discifera. Based on the new identifications, we argue that T. discifera does not occur in the Cerrado.

The objective of this work was to undertake a qualitative assessment of earthworm diversity in areas under human influence, in a region of Cerrado-Pantanal-Amazon rainforest transition, in the state of Mato Grosso, Brazil. The earthworms were collected in the municipalities of Barra do Bugres and Arenápolis, and were studied together with species previously identified from other municipalities. Seventeen municipalities, at 29 sampling points of Mato Grosso State, have been sampled. Seven species of earthworms were collected and identified in Barra do Bugres: Goiascolex vanzolinii, Pontoscolex (Pontoscolex) corethrurus, Opisthodrillus borellii borellii, Opisthodrillus sp., Dichogaster (Diplothecodrilus) gracilis, Dichogaster sp. and a species of the Criodrilidae family. Four species of earthworms were identified in Arenápolis: Pontoscolex (Pontoscolex) corethrurus, Dichogaster (Diplothecodrilus) gracilis, Dichogaster (Diplothecodrilus) affinis and Dichogaster sp. In total, 32 earthworm species/subspecies are known from Mato Grosso, 22 native and 10 exotic.

Rainfall predominantly influences economic activity in northern of MatoGrosso.  The scarcity of rainfall limits agricultural production, and its excess hinders the flow of production on back roads.  These obstacles impose the need for greater knowledge of rainfall in distant regions of the state, such as Paranorte, in Juara-MT.  This study aimed to identify the beginning and end of the rainy season, as well as the frequency and duration of dry days, besides to investigate causal relationships of rainfall with ENSO (El Niño de Oscillation Sul) phenomena.  Methods based on rainfall quantity and continuity were adopted.  The results showed that in Paranorte, the accumulated annual precipitation varies between 2322 and 2720 mm.  The months of the year are divided into a dry period (June, July and August), a period of low rainfall (May and September - ≈ 80 mm) and a period of high rainfall (October, November, December, January, February, March and April, with 214 to 464 mm).  Prolonged droughts occur most often at the beginning (September) and end (May) of the rainy season. In turn, ENSO phenomena influence rainfall only in spring.

The landscape of the northern Pantanal region is a mosaic of fields and forests, distributed according to topography and hydrology of this floodplain, resulting in a particular pattern of vegetation distribution. Among the forest formations, mixedspecies and monodominant landscape units can be found which are associated with floodable or non-floodable habitats. Our study tested the hypothesis that forest formations with greater tree richness and which are non floodable (cordilheiras) maintain distinct richness and composition in canopy ant assemblages in relation to the seasonally floodable monodominant forests (cambarazais). Sampling was performed in 10 sample areas (five cambarazais and five cordilheiras) by means of canopy insecticide fogging during the dry and high water seasons of the Pantanal’s hydrological cycle. The canopy ant assemblages revealed 105 species belonging to 30 genera and nine subfamilies. Myrmicinae (41 spp.), Formicinae (20 spp.) and Pseudomyrmecinae (17 spp.) predominated. Our results revealed that the composition of canopy ant assemblages varied between cambarazal and cordilheira forests, as well as between the dry and high water periods. Nevertheless, the richness was homogeneous between these forests and in the dry and high water periods. These results show the specificity of each forest, as well as its structure, in maintaining distinct compositions in ant assemblages in canopies in the Pantanal of Mato Grosso.
