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.

Interactions between the Cerrado (Brazilian Savanna) biota and fire are of extreme interest because these factors are intimately related and could be determinant in plant populations maintenance. For 12 months, we studied the phenology of two Cerrado native species (Enterolobium gummiferum (Mart.) J.F.Macbr. and Caryocar brasiliense Cambess.) under two fire regimes: the first was burned every two years on August (PBM) in a control site without fire for 14 years (PC). Uniformity tests were made to verify seasonality of each phenological phase. The model selection with Akaike information criterion was made using climatic variables of the study region to identify which variables better describe the phenological phases. Fruit production was estimated for both treatments. Almost every phenophase showed production peaks, except for leaf sprout of C. brasiliense in PC and leaf fall of C. brasiliense in the two treatments, and E. gummiferum in PC. In general, the phenological behaviour of both species did not differ from other studies. However, fire retarded the leaf renewal and inhibited the reproductive phases of C. brasiliense, similar to previous results for other Cerrado native species in regions with burn incidence.

The effect of fire on the abundance of some Xenarthran mammal species Priodontes maximus Kerr, 1792 (giant armadillo), Euphractus sexcinctus Linnaeus, 1758 (yellow armadillo) and Myrmecophaga tridactyla Linnaeus, 1758 (giant anteater)) was studied at Reserva Xavante do Rio das Mortes, a 329 000 ha Xavante Indian reserve in the Cerrado of Mato Grosso, Brazil. Track counts were used to compare the abundance of these mammals along seven burned and seven unburned transects, on seven occasions between August 1995 and August 1996. The number of tracks in burned and unburned areas did not differ. Xenarthrans probably use burned areas to obtain food resources, basically termites and ants. Xavante traditional fire hunts may reduce fuel accumulation and function as a mechanism to prevent more destructive fires. Fire management at Reserva Xavante is recommended because the burning system of Brazilian farmers is already influencing the Xavante community. Xavante traditional knowledge about fire could be an important instrument for this management.

Existem poucas informações sobre as interações entre frugívoros e a palmeira. Os estudos tinham como objetivo determinar os consumidores do fruto do buriti e analizar a importância de cada um deles. Coletamos dados de disponibilidade de frutos revisando 100 buritis e anotando a presença de frutos maduros, em todo o período de trabalho. A utilização de frutos de buriti por aves frugívoras foi estudada através da observação direta dos cachos em três buritis. As observações incluíram freqüência de visitas, tamanho do bando, número de frutos consumidos e comportamento de forrageamento. Também colocamos três coletores de frutos embaixo de tres cachos de buriti para determinar taxas de queda dos frutos. Oito espécies de aves comeram os frutos do buriti e os psitacideos foram os principais consumidores, especialmente Orthopsittaca manilata. Os frutos de M. flexuosa são um importante recurso alimentar para frugívoros na estação seca, quando frutos são escassos no cerrado.
