Species Diagnosis

We describe a specimen of Apostolepis phillipsi Harvey, 1999, from Vila Bela da Santíssima Trindade, Mato Grosso, establishing the first unambiguous record of the species in Brazil. The new locality is ca. 120 km from the type locality, in Bolivia. We present an updated species diagnosis, the first image of a living specimen, and the first description of A. phillipsi coloration in life. Even though the Brazilian range of A. phillipsi lies within a protected area (Parque Estadual Serra Ricardo Franco—PESRF), it is threatened by cattle raising, logging and agriculture. PESRF lacks formal delimitation and a management plan, and the Mato Grosso State Legislature is considering a decree to extinguish PESRF, which could cause the extirpation of the Brazilian range of several endemic species.

Hummingbirds are the main vertebrate pollinators in the Neotropics, but little is known about the interactions between hummingbirds and flowers in areas of Cerrado. This paper aims to describe the interactions between flowering plants (ornithophilous and non-ornithophilous species) and hummingbirds in an urban Cerrado remnant. For this purpose, we investigated which plant species are visited by hummingbirds, which hummingbird species occur in the area, their visiting frequency and behavior, their role as legitimate or illegitimate visitors, as well as the number of agonistic interactions among these visitors. Sampling was conducted throughout 18 months along a track located in an urban fragment of Cerrado vegetation in Campo Grande, Mato Grosso do Sul, Brasil. We found 15 species of plants visited by seven species of hummingbirds. The main habit for ornithophilous species was herbaceous, with the predominance of Bromeliaceae; among non-ornithophilous most species were trees from the families Vochysiaceae and Malvaceae. Hylocharis chrysura was the hummingbird that visited the largest number of plant species and also attended the greater number of agonistic events. The high proportion (66.7%) of non-ornithophilous species visited by hummingbirds in the present study was similar to that found in other communities analyzed in Brazil. The fact that ornithophilous species in the area does not offer resources continuously throughout the year should induce hummingbirds to search for alternative resources, and contribute to the high proportion of non-ornithophilous species visited. In general, the floral form was not a barrier to floral visits by hummingbirds, although morphological characteristics of flowers from some plant species may be restrictive. Tabebuia aurea, for example, presents flowers with long corollas, hindering the access to floral resources by the pollinators, what may favor the occurrence of illegitimate visits by hummingbirds. Despite of being a small fragment of Cerrado vegetation, the studied remnant can be considered an important refuge, sheltering a great richness of hummingbird species comparable to several forested areas in Brazil.

ABSTRACTCerrado is a species-rich savanna-like vegetation that covers a large area in central Brazil. Soil, and particularly soil fertility, is considered to be the major factor determining the wide and diverse physiognomic-floristic gradients encountered within cerrado vegetation. To describe the vegetational variations within a cerrado in southern Mato Grosso state (15° 21'S, 55° 49'W), a 1 ha transect was located to pass through an interfluvial cerrado and climb a steep talus slope. The vegetational and environmental variations are described by means of field classification, direct gradient analysis and reciprocal averaging ordination. The effects of differences in ground water regime in the interfluvial cerrado and differences in inclination with associated rockiness in the talus cerrado are related to the vegetational variations. As the soils are very similar in texture and in the majority of chemical properties, the role of the above environmental factors was more easily distinguished. In the interfluvial cerrado, the vegetation variations are probably related to the seasonal fluctuation in water table level.

The present study was developed aiming to evaluate the richness and biogeography of social wasp species in the Brazilian savanna, Cerrado. In order to do so, we gathered data from specialized literature and field samplings performed at Sempre-Vivas National Park, northeastern Minas Gerais state. 18 genera and 137 species were recorded, with 4 endemic species of the Mischocytiarus genus. The results showed that Cerrado houses 40% of Brazilian Polistinae fauna and that Sempre-Vivas National Park is responsible for around 29% of this value, which makes it an important refuge for conservation of social wasps from Cerrado, as well as Mato Grosso state, due to its large number of restricted occurrence and endemic species. Nonetheless, there are Brazilian states and conservation units still lacking information for the taxon, making a bigger sampling effort in the Cerrado biome necessary, as it has been rapidly deteriorating due to human action.

Abstract The Brazilian Cerrado is the second largest Neotropical biome and an important hotspot of biodiversity. However, land use change in this ecosystem is producing landscapes with modified natural environments and anthropogenic environments, such as exotic pastures. In this study, we evaluated how conversion of native Cerrado vegetation to exotic pastures affects the dung beetle assemblages (Coleoptera: Scarabaeidae: Scarabaeinae). We sampled dung beetles in four areas of Cerrado (sensu stricto) and in four areas of exotic pastures (Urochloa spp.) in Aquidauana, Mato Grosso do Sul, Brazil. In all, 7,544 individuals from 43 species of dung beetles were collected, and 19 species were found in both the Cerrado and exotic pastures. The abundance and species richness of dung beetles were higher in Cerrado remnants. Species composition differed between Cerrado and exotic pastures, where 11 species were classified as specialists of Cerrado, 10 species were considered specialists of exotic pastures, and 6 species were habitat generalists. Roller beetles were most negatively affected by exotic pasture establishment. We demonstrated that exotic pasture establishment has a negative impact on dung beetle assemblages in Brazilian Cerrado. The decline in abundance and richness of roller beetles has important implications for the understanding of ecosystem functioning because it can reduce the ecological functions performed by dung beetle assemblages in exotic pastures. Finally, the high number of dung beetle species shared between Cerrado and exotic pastures suggests that the Cerrado remnants is a fundamental requirement for the conservation of biodiversity of dung beetles in exotic pastures in the Brazilian Cerrado.

There is an urgent demand to evaluate and document the environmental conditions of the territories of indigenous people. This is basic in the efforts to achieve sustainable development goals adopted by all United Nations Member States in 2015. The Xavante people are hunters/gatherers and depend on natural resources for their physical, spiritual, and cultural survival. Their lands are localized in the state of Mato Grosso, Brazil, in a transitional area between the Cerrado vegetation and the Amazon rainforest. They have been developing environmental projects ~in order to manage their territory correctly for decades, as part of their survival strategy. In recent fieldwork, we stated that some major game species may still be abundant in the territory and we suggest that certain wildlife management measures in the past may be responsible for this. We easily registered most game species handled by the Xavantes, except for some edentates that were rarely detected. We confirm the giant anteater as the most vulnerable species to hunting effects. In this article, we point out the main threats for the territory and present new recommendations that may be fundamental for the conservation of biodiversity in the region and the survival of the Xavante people.

The Pantanal is a biome that lives under water conditions and resists to two very distinct periods: flooded and drained. The objective of this study was to evaluate the behavior and quantify the microbial biomass during the flood period, in soils under riparian forest and cerrado vegetation in Mato Grosso State pantanal, at two depths. At depths of 0.00-0.05 m, the highest levels of C-BM and RB were found in cerrado soils; for the metabolic quotient no differences were observed in the two vegetations; the total organic carbon content was higher in riparian forest soils and the microbial quotient was higher in cerrado soils. Bacteria and fungi were found to be more abundant in the cerrado soil at the two evaluated depths and the actinomycetes in the forest. It is concluded that in the flood period there are the presence of active microorganisms which produce a differentiated biomass due to the phytophysiognomy of the location.

First Time

The Hoary Fox Lycalopex vetulus, is a small omnivore-insectivore canid inhabiting open environments/areas of the Brazilian savannah, whose spatial organization and territoriality is still unknown.  Space use and social organization of two breeding pairs with adjacent home ranges were determined through radio tracking from October 2002 to April 2003 in a mosaic of cultivated pastures and Cerrado vegetation in eastern Mato Grosso, Brazil.  Home ranges were 140–299 ha in size, with individual areas of the male and female in each breeding pair overlapping extensively.  After the death of both individuals of one pair, the neighboring pair progressively occupied the vacant space, expanding markedly its range into about half the area originally occupied by the previous pair.  Factors driving a pair of Hoary Foxes to expand their territory into a vacant area after death of the neighboring pair were not clearly determined.  Absence of territorial defence, however, could have contributed to the range shift observed.  This is the first time that the response of neighboring foxes to social disruption of an adjacent pair has been documented for Hoary Foxes.
