The purpose of this study was to evaluate the integrity of two forest fragments in Rio Negro Pantanal sub-region, using coleopterans as environmental indicators. The study was carried out at Santa Emilia Farm in the Rio Negro sub-region, municipality of Aquidauana, Mato Grosso do Sul (19º 30' 18'' S and 55° 36' 45'' W). Two sites were selected, locally denominated as "cordilheiras" (narrow and elongated strands of elevated soil), one with low degree of anthropic disturbance (CL) and the other, currently undergoing restoration process (TD). The sampling sites were determined using a GPS device. Ten pit-fall traps containing water and detergent were used for the specimens sampling, which were screened and identified. Abundance, richness, diversity and similarity were determined. Abundance was higher for CL (n = 277) than for TD (n = 251). The same was observed for the diversity indices, CL showed H' = 2.83 bit.individual-1 and TD = 2.48 bit.individual-1, confirming the interferences made for abundance. Specimens of ten families were captured in CL area and seven families in TD area, indicating higher richness in CL, when compared to TD. The linear correlation coefficient (p > 0.05) indicates that both areas are significantly different, showing similarity value of 66.7%. The data show that the structure and disturbance degree in the environment integrity influence the composition of beetles fauna, causing the increase of abundance, richness and diversity in anthropogenic environments undergoing the early stage of regeneration.

AbstractAcari ectoparasites were collected from bats during 12 months in the Rio Negro farm (19°34′22″S and 56°14′36″W), Aquidauana, Mato Grosso do Sul. A total of 654 bats belonging to the families Phyllostomidae, Noctilionidae, Molossidae, Vespertilionidae and Emballonuridae were captured. Only 136 bats of nine genera and 11 species were parasitised. Periglischrus iheringi Oudemans was the most abundant mite species, and this prevalence may be related to the low degree of host specificity of this species and due to the broad geographical distribution of its hosts. The greatest mean intensity was found to Periglischrus torrealbai Machado-Allison on Phyllostomus discolor Wagner (Phyllostomidae) and Periglischrus tonatii Herrin and Tipton associated with Lophostoma silviculum d’Orbigny (Phyllostomidae), which also had the highest prevalence of infestation.

The main purpose of this study was to investigate natural infection by Leishmania in phlebotomine females in a visceral-leishmaniasis focus in Antonio João county in Mato Grosso do Sul State, Brazil. Between June and October 2003, the digestive tracts of 81 females captured in Aldeia Campestre, Aldeia Marangatu and Povoado Campestre were dissected. The females were separated by species, location, area and date of capture into 13 groups and kept in ethanol 70%. To identify the Leishmania species using the PCR technique, amplifications of the ribosomal-DNA (rDNA) and mini-exon genes were analyzed. Of the 81 specimens, 77 (95%) were Lutzomyia longipalpis, making this the most common species; only one specimen of each of the species Brumptomyia avellari, Evandromyia cortelezzii, Evandromyia lenti and Nyssomyia whitmani was found. Trypanosomatids were identified in eight of the nine groups of Lutzomyia longipalpis (10.39%) one group from Aldeia Campestre, one from Aldeia Marangatu and six from Povoado Campestre; of the eight groups, one from Aldeia Marangatu and another, with promastigotes forms also confirmed by dissection (1.23%) from Povoado Campestre, were identified by PCR as Leishmania chagasi (2.6%). The other groups gave negative results. These findings indicate that there is a high risk of leishmaniasis transmission in this area.

A biodiversidade do Pantanal é praticamente desconhecida, principalmente em relação aos fungos. Em conseqüência da devastação pelo avanço da pecuária, grande parte da vegetação natural em áreas de fácil acesso foi suprimida, restando fragmentos de cerrado, extensas pastagens e leiras formadas pelo acúmulo da madeira derrubada. Em alguns locais, como na região do Pantanal do Rio Negro, parte da vegetação nativa foi relativamente preservada e nela, durante o ano de 2006, foram realizadas cinco excursões de coleta de fungos, nos períodos mais secos. Cinqüenta e seis espécies de Basidiomycetes e uma de Ascomycetes macroscópicos foram identificadas. Todas as espécies estão sendo citadas pela primeira vez para o Estado de Mato Grosso do Sul e região do Pantanal, e Collybia bakeri Dennis, Entoloma cerussatum Pegler, Epithelopsis fulva (G. Cunn.)

ABSTRACT The ecological restoration of degraded areas using seeds collected in forest remnants has shown significant results. This study was developed to verify the potential of seed rain to regenerate forest fragments of a Permanent Preservation Area (PPA) in the Apa River Basin which is located in the southwestern portion of the Mato Grosso do Sul state, Brazil. To develop the study, we installed 25 collectors measuring 1 m2 each, which were systematically distributed on an area of 1.5ha. Seed gathering was conducted in a monthly basis throughout the year of 2013. A total of 26.411 propagules were identified and distributed among 50 species, 45 genera and 32 families. In terms of the propagules distribution, 70.51% were identified as trees, 22.8% as lianas, 6.5% as shrubs, 0.1 as herbaceous, 0.05% as palm and 0.05% could not be classified. The value for the Shannon Diversity Index was (H') = 1.67 and the Pielou Evenness index was (J) = 0.42. These results indicate that the seeds rain has low species diversity with the abundance of a few species. The overall results suggest that seed rain can be a potential technique for restoration of the PPAs and other forested areas. However, it is necessary to enhance the diversity of tree species.

TBCs are ventures formed by entrepreneurs whose core is technical knowledge and which are sometimes accompanied by business incubators. It is estimated that the earnings of TBCs incubated in Brazil are more than R$550 million and that they generate around 14 thousand jobs. Thus, given the importance of TBCs for a country's social and economic development, this research is justified, which aims to measure the innovative capacity of TBCs linked to incubators of Brazilian technology-based companies. The chosen methodology was descriptive research, of quantitative nature, whose data collection technique uses the Innovation Radar questionnaire. The sample of this study had the participation of 62 incubated in the incubation stage in 22 incubators located in the states of Goiás, Mato Grosso, Mato Grosso do Sul, Minas Gerais, and Distrito Federal. Among other results, the study showed that, in a sectorial analysis, mining companies in the service sector are not very innovative and the other occasional innovators, as well as that the industries of Mato Grosso do Sul are not very innovative and the other occasional innovators. Finally, in comparison, all TBCs that participated in the research are occasional innovators, that is, in general, the entire sample was characterized as an occasional innovator.

Litter Sampling

This study aimed to evaluate the potential of litter and litterfall as ecological indicators in three sites in restoration process located in Ivinhema, Jateí and Caarapó – Mato Grosso do Sul state, Brazil, after 12, 13 and 16 years of implantation, respectively. The objective was also to obtain Pearson's simple linear correlation) between monthly litterfall with environmental variables of rainfall and air temperature. To litterfall sampling, 15 litter traps were used (0.80 m x 0.80 m) and, for litter sampling, six collections were carried out in each restoration site, in December 2016, using a frame (0.64 m2). The samples were separated into three components: leaves, twigs, reproductive material (flowers and fruits). The high litter amount, in the three sites evaluated (Ivinhema 9.4 Mg ha-1; Jatéi 5.5 Mg ha-1; and Caarapó 7.1 Mg ha-1), demonstrates the importance of litterfall and litter as an indicator for the stages initial succession in restored forests. There were weak correlations between litter and environmental variables, being negative for air temperature and positive for rainfall.This study aimed to evaluate the potential of litter and litterfall as ecological indicators in three sites in restoration process located in Ivinhema, Jateí and Caarapó – Mato Grosso do Sul state, Brazil, after 12, 13 and 16 years of implantation, respectively.
