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.

Seed rainfall may be one of the mechanisms most impacted by livestock production in forest remnants. The trampling and cattle grazing alter dynamics, structure and floristic composition of the forest. The present work characterized the seed rainin forest remnants and the possible impacts of the presence and the management regime with different cattle stocks in the Pampa biome, southern region of Brazil. We compared three areas in Seasonal Forest remnants with a management history of 43 years: cattle exclusion area (A1); area with a cattle stock of 0.5 ua ha-1 (A2); and area with cattle stock of 1.0 ua ha-1 (A3). The seed rain was collected quarterly in 16 collectors (1 × 1 m²) per area for 24 months. The seeds were counted and identified according to external morphological characteristics, habit and dispersion syndrome. Shannon diversity index, submitted to the Hutcheson test, Pielou evenness, expected diversity and floristic similarity were determined. The results indicated that the impacts caused by livestock to seed rain were more significant in A3 where a quantitative reduction in the number of seeds was observed, probably due to the low number of plant individuals that make up the community.

The Atlantic Forest is highly anthropized, this reduce the areas of native vegetation and impacts the biodiversity of the biome. The objective of this study is to analyze forest remnants with native vegetation characteristics using a free GIS. This analysis takes place using landscape metrics and was based on the supervised vectorization of land use in the municipality of California, PR. The area of the vectored polygons was obtained and a classified, and then the calculation was made with the nearest neighbor index, mean distance observed, Patton diversity index and the perimeter/area ratio of forest fragments. The results show that most of the fragments have an area smaller than 1 ha, the fragments with more significant area (<50 ha) represent more than 16% of the native vegetation area. The small fragments are important to maintain the connectivity, since the withdrawal of these increases the mean distance observed and nearest neighbor index. Most of the fragments are elongated and amorphous in accordance with the perimeter/area ratio and the Patton diversity index respectively, this may demonstrate the fragments may be subject to edge effects. Even with these characteristics, these fragments may be part of what is planned in public policy for preservation in the Atlantic Forest in the state of Paraná. Therefore, even small fragments with little core area are important for maintaining biodiversity, especially in a highly anthropogenic landscape

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.

This study aimed to evaluate how the surrounding vegetation affects the assemblage of fruit flies. For this, flies were collected in guava orchards with distinct types of surrounding vegetation (exotic pasture, native forest and fruit tree intercropping). The experiment was conducted in Itaporã and Dourados, State of Mato Grosso do Sul, Brazil. Weekly samples were collected from March to April 2015. McPhail traps were baited with 5% hydrolyzed corn protein. Species richness, diversity index and abundance were evaluated for each orchard, as well as the species composition of fruit fly between the environments surrounding the orchard and, finally, the sex ratio. A total of 579 individuals were collected of the species Anastrepha fraterculus, A. montei, A. obliqua, A. sororcula, A. striata, A. turpiniae and A. zenildae. The orchard surrounded by native forest had the highest species richness and Shannon diversity. The species composition differed between environments, with the formation of three distinct groups. The environment surrounding the guava orchard influences the richness, diversity, abundance and sex ratio of fruit flies, indicating that the native forest may provide more resources for the maintenance of these insects.

The ichthyofauna from 3 streams (Água Boa, Perobão, and Santa Maria) to the lower Iguatemi River were inventoried, which is located in the upper Paraná river basin, in Mato Grosso do Sul state, Brazil. Sites in the upper, intermediate, and lower portions of each stream were quarterly electrofished from March to December 2008. All sampled fish (n = 6,816 individuals) represented 43 species of 5 orders, and 16 families. The most abundant species was Phalloceros harpagos (63.5%), followed by Astyanax aff. paranae (10.6%), Hypostomus ancistroides (5.9%), Gymnotus inaequilabiatus (3.4%), and Knodus moenkhausii (2.7%). Despite the high ichthyofauna richness in the lower portion of Iguatemi River, the need to implement and/or expand soil conservation practices and riparian forest restoration is of utmost importance to maintain these populations in the long term.

AbstractBirds can be used as bioindicators to evaluate the quality of a habitat. The objective of this study was to record richness and abundance of bird communities in two semi-deciduous forest fragments in Brazil (Olavo Egydio Setubal – OES; and Igurê – IGR). A subsequent analysis and comparison of the avifauna structure in each of the fragments were made including previous studies in the same areas. Point counts methodology was chosen for each fragment along 12 months. The results showed the occurrence of a total of 129 bird species for both areas. Although we registered 102 species for each site, Shannon-Wiener diversity index and Pielou’s evenness index, respectively, were slightly higher in OES (

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.

Dung beetles (Coleoptera: Scarabaeoidea) in three landscapes in Mato Grosso do Sul, Brazil. Dung Beetles are important for biological control of intestinal worms and dipterans of economic importance to cattle, because they feed and breed in dung, killing parasites inside it. They are also very useful as bioindicators of species diversity in agricultural or natural environments. The aims of this paper were to study the species richness, and abundance of dung beetles, helping to answer the question: are there differences in the patterns of dung beetle diversity in three environments (pasture, agriculture and forest) in the municipality of Dourados, in the state of Mato Grosso do Sul. A total of 105 samplings were carried out weekly, from November 2005 to November 2007, using three pitfall traps in each environment. The traps were baited with fresh bovine dung, and 44,355 adult dung beetles from 54 species were captured: two from Hyborosidae and 52 from Scarabaeidae. Five species were constant, very abundant and dominant on the pasture, two in the agricultural environment, and two in the environment of Semideciduous forest. Most of the species were characterised as accessories, common and not-dominant. The species with higher abundance was Ataenius platensis Blanchard, 1844. The indexes of Shannon-Wiener diversity were: 2.90 in the pasture, 2.84 in the agricultural environment and 2.66 in the area of native forest. The medium positive presence of dung beetles in the traps in each environment were: 36.88, 42.73 and 20.18 individuals per trap, in the pasture, agricultural environment and in the native forest, respectively. The pasture environment presented a higher diversity index. The species diversity of dung beetles was superior where there was higher abundance and regularity of resource (bovine dung).
