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.

Phytoseiidae is the most extensively studied family of predatory mites, some of which are effectively used as biological control agents. Nevertheless, studies of these mites in some Brazilian biomes such as the Pantanal are still scarce. The objective this publication was to assess the diversity of this family in Pantanal vegetation from Mato Grosso do Sul State, Brazil, verifying the importance of the native plants as reservoirs for these mites. Samplings were carried out in five phytophysiognomies of the Pantanal: Cambarazal, Capão (forest islet), Carandazal, Riparian Forest and Paratudal. Thirty-five phytoseiid species were recorded on 40 plant species of 28 families. The most common species were Amblyseius chiapensis De Leon and Euseius concordis De Leon, recorded on 21 and 18 plant species, respectively. Inga vera Willd. (Fabaceae) and Paullinia pinnata L. (Sapindaceae) were the host plants harboring the greatest richness of phytoseiids, 15 and 14 species, respectively. Our results suggest a high diversity of phytoseiid mites in the Pantanal biome. However, as only a small proportion of the total biome area was considered, only a fraction of the mite diversity was probably recovered. Thus, new studies on this biome are needed, especially in other well-preserved native vegetation remnants.

The temporal and spatial resource use among hummingbirds was studied over 13 months in an urban forest remnant (Prosa State Park: PSP) in Campo Grande, Mato Grosso do Sul, Brazil. Hummingbird visitation was recorded at three ornithophilous and eleven non-ornithophilous species. Flower density was roughly constant during the study period, with the density of non-ornithophilous flowers being higher than that of ornithophilous ones. Mean values of nectar volume and concentration were similar between ornithophilous and non-ornithophilous species. Eight hummingbird species were observed at PSP: Amazilia fimbriata, Anthracothorax nigricollis, Chlorostilbon lucidus, Eupetomena macroura, Hylocharis chrysura, Florisuga fusca, Thalurania furcata and an unidentified species. Hummingbird visit frequencies to ornithophilous and non-ornithophilous flowers were similar. However, some non-ornithophilous species received a higher number of visits, which seems to be related to their large number of open flowers per plant per day. The number of feedings bouts of hummingbirds increased with the total number of flowers observed per focal plant. All recorded species of hummingbirds visited non-ornithophilous flowers, predominantly melittophilous and generalised entomophilous flowers. Hummingbird species recorded at PSP may be viewed as generalists, visiting a large number of non-ornithophilous species. Despite being an urban forest, PSP is relatively rich in hummingbird species, suggesting that it provides important shelter and foraging sites for hummingbirds in such an environment.

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.

The Pacu Piaractus mesopotamicus is the most captured fish species in the Pantanal, Mato Grosso do Sul State, and since 1994, its maximum sustainable yield had already been exceeded. Its capture is carried out only by hooks, as mesh gears are forbidden either for professional or for recreational fishing. The aim of this study was to determine selectivity for different hook sizes used in P. mesopotamicus fishing and to verify which sizes capture only adults. Data were collected in the rivers Miranda, Aquidauana, and Vermelho, in January, March, and April 2002. Six longlines with eight hook sizes were used and we adopted the hook opening as a measure related to selectivity. Different hooks captured individuals of the same length and their medians were similar, evidencing the great overlap among sizes. Regression results showed no significant relationship between ln[c2 (l)/c1 (l)] and total length of captured individuals. In addition, the Kolmogorov-Smirnov test also did not detect significant differences in the size of captured fish. Several hypotheses, such as the selectivity models, shape of selection curves, scarcity of large fishes, and behavior are used in order to explain the absence of hook selectivity for this species. Size of recruitment for this gear was 28 cm of total length, when individuals are still immature.

ABSTRACT Plutella xylostella L. is one of the main agents to cause damages to plants of Brassica genus, provoking negative impacts in cultures. The use of botanical extracts in plants protection has been related in literature, however, their use in the species analyzed in this study is not yet reported. We assessed the effect of aqueous and methanolic extracts of the species: Schinus terebinthifolius Raddi (Pink Pepper), Annona coriacea Mart. (Araticum), Duguetia furfuracea (A. St.-Hil.) Benth. & Hook. (Pindaúva do campo) and Trichilia silvatica C. DC. (Catiguá-branco), occuring in the state of Mato Grosso do Sul and whose feeding preference of P. xylostella larvae of 3rd instar. We intend to answer the following questions: (1) Are the plant species analyzed fagodeterrentes? (2) what type of extract produces the least food preferrence? To answer these questions, we treated cabbage disks with aqueous extracts stored in a refrigerator in periods of 0, 7, 14 and 21 days and the methanolic extracts were treated at concentrations of 0.5 mg/mL, 1.0 mg/mL, 2.0mg/mL. The aqueous and methanolic extracts of T. silvatica presented the lowest values of feeding preference, 0.113 and 0.06, respectively, compared to other extracts.

An analysis was made of the floristic composition of 98 areas of cerrado and Amazonian savanna, encompassing most of the area of such vegetation in Brazil. A total of 534 species of trees and large shrubs were recorded for these areas, of which 158 (30%) occurred at a single site only. Such unicates and taxa without determinations to specific level were excluded from the study since they provide no basis for comparison. The data were analysed by three techniques of multivariate analysis: (a) a divisive hierarchical classification by Two-way Indicator Species Analysis (TWINSPAN). (b) an agglomerative hierarchical classification by UPGMA (Unweighted Pair-Groups Method using Arithmetic Averages) using the Sørensen Coefficient of Community (CC) as a measure of similarity, and (c) an ordination by Detrended Correspondence Analysis (DCA). The results from all three methods showed great similarity, demonstrating a strong geographic pattern in the distribution of the flora of the cerrado biome and allowing the recognition of southern (Sâo Paulo and S Minas Gerais), southeastern (largely Minas Gerais), central (Federal District, Goiás and parts of Minas Gerais), central-western (largely Mato Grosso, Goiás and Mato Grosso do Sul) and northern groups (principally Maranhão, Tocantins and Pará), as well as a disjunct group of Amazonian savannas. Soil type (mesotrophic or dystrophic) is an important factor in determining floristic composition. The study demonstrated that cerrado vegetation is extremely heterogeneous: none of the 534 species occurred at all sites and only 28 species were present at 50% or more.

Abstract The objective of this study was to assess air quality in relation to vehicular traffic flow in cities located at different elevations in the Bodoquena microregion, state of Mato Grosso do Sul, Brazil. To do so, a micronucleus test was carried out using the TRAD-MCN bioassay on young Tradescantia buds collected from February to November 2018 in seven cities of the microregion with different traffic flow intensities. Meteorological parameters were evaluated, and vehicular traffic was counted to determine traffic flow in each city. With data from the Shuttle Radar Topography Mission (SRTM) and processing in Esri ArcGIS® software version 10.5.1, the regions was mapped based on an Elevation Model. Morphoanatomical analyses were performed according to standard methodology. Measurements were taken of thickness, length and width of tissues and structures, including the upper and lower cuticle, upper and lower epidermis, hypodermis and mesophyll. The greatest traffic flow was found in the cities of Bodoquena, Guia Lopes da Laguna, Jardim, and Porto Murtinho, with the period from 5:00 to 6:00 p.m. showing the highest traffic flow. The greatest frequency of mutagenic alterations was found in the city of Guia Lopes da Laguna, although the results did not differ significantly from Bonito, Caracol, and Jardim. Throughout the biomonitoring, the summer and autumn seasons showed the greatest micronuclei frequencies in all evaluated cities. Variations in the tissue/structure thickness was observed across cities and seasons, but with a decrease in thickness during autumn. In general, the tissues/structures were smaller for the cities of Nioaque and Porto Murtinho, while the anatomical and morphological characteristics of leaf length and thickness showed no differences among cities. We found limited correlation between micronuclei frequency and traffic flow, supporting the hypothesis that although mutagenic alterations are observed in T. pallida, in this microregion the changes are numerically lower when compared to other regions of the state. In light of the genotoxic and morphoanatomical factors assessed herein, the Bodoquena microregion appears to be well preserved in terms of air quality, presenting low micronuclei frequency and a limited reduction in tissues and leaf structures, regardless of the season.

Phytophagous mites belonging to the family Tetranychidae are considered pests of a wide range of plant species of agricultural importance in the Annonaceae family. This study aimed to reports the occurrence and attack symptoms of the mite Tetranychus mexicanus (McGregor) (Acari: Tetranychidae) on soursop seedlings (Anonna muricata L.). High mite infestation on the leaves of soursop seedlings was reported in a seedling production nursery made of black Sombrite® screen with 35% restriction of full daylight, located at the State University of Mato Grosso do Sul (UEMS), in Cassilândia, MS, Brazil, during the month of October 2015. Attack symptoms were on the adaxial side of the leaves, whereas mite colonies were located on the abaxial face of the leaves. The injuries started by yellowing of the leaves and curled edges, and later by the fall of the attacked leaves. This is the first record of the occurrence of T. mexicanus in soursop seedlings produced on agricultural screenhousein the state of Mato Grosso do Sul, Brazil.
