Identifying large-scale patterns of variation in pollinator dependence (PD) crops is important from both basic and applied perspectives. Evidence wild plants indicates that this can be structured latitudinally. Individuals populations at high latitudes may more selfed less dependent on pollinators due to higher environmental instability overall lower temperatures, conditions affect availability. However, whether pattern similarly present remains unknown. Soybean (Glycine max), one the most...
Inundation and fire can affect the structure of riparian vegetation in wetlands. Our aim was to verify if there are differences richness, abundance, basal area, composition topographic preference woody species forests related history, flooding duration, or interaction between both. The study conducted Paraguay River some which were burned three times 2001 2011. We sampled trees with a girth at least 5 cm breast height 150 × 10 m plots (79 71 unburned). also measured flood mark estimated...
The number of open flowers on a plant (i.e., floral display size) can influence fitness by increasing pollinator attraction. However, diminishing marginal returns with are expected as pollinators tend to visit more per consecutively. An extended flower visitation sequence increases the fraction ovules disabled self-pollination (ovule discounting) and reduces plant's own pollen that is exported sire seeds in other plants (pollen discounting). Hermaphroditic species genetic system prevents...
Abstract Aim Plant reliance on animal mutualists is expected to decrease with latitude owing increasing environmental instability. As a consequence, more erratic pollination in the temperate zones than tropics could translate into lower efficiency pollen transfer, and thus wastage. Despite relevance of this hypothesis for plant reproductive evolution, implications proposed latitudinal gradient pollinator reliability ovule production, traits directly affecting seed siring set, respectively,...
Bats have been increasingly studied in the last 15 years Mato Grosso do Sul, and several records were not yet considered reviews of South American bat distributions. Here, we present species their distributions Sul based mainly on data compilation from literature, but also complementary information zoological collections, our colleagues’ unpublished records. We found 74 bats within 42 genera seven families already reported Sul. Bat this state represent 44% Brazilian’s (≅ 169) 7% world’s...
Abstract We updated the checklist of mammals from Mato Grosso do Sul, Brazil based on primary records only. One hundred and sixty-six mammal species were listed as occurring in state, 47 them being medium to large, small 73 bat species. The are distributed 31 families: Didelphidae (17 spp.), Dasypodidae (7 Myrmecophagidae (2 Cebidae (1 sp.), Callithrichidae Aotidae Pitheciidae Atelidae Leporidae Felidae Canidae (4 Mustelidae (5 Mephitidae Procyonidae Tapiridae Tayassuidae Cervidae Sciuridae...
Habitat quality and its availability affect the structure of communities at a variety different spatial environmental scales, including habitat landscape levels. Analyses conducted multiple scales have demonstrated importance patterns with regard to community structure. We used multi-scale approach better understand composition small mammal in central Brazil. delimited 24 sampling units for purpose investigating response habitat, patch, while evaluating each as well configuration...
The balance between stochastic forces and frequency-dependent mating largely governs style morph frequencies in heterostylous populations. In clonal species, deviations from equal ratios often result founder events unfavourable conditions for sexual reproduction. aim of this study was to investigate whether different flooding regimes, because their influence on vs. reproduction, are associated with regional variation floral trait differentiation populations the clonal, tristylous, aquatic...
Summary The association of species distribution and abundance patterns with environmental spatial variables is often used to identify signatures niche‐based processes in metacommunity structures. If there no association, however, then stochastic may be interpreted as a possible factor driving community assembly. We sampled 20 ponds more than 5800 adult individual anurans one the world's largest Neotropical wetland systems, where an annual unimodal flood pulse most important force operating...
Many eukaryotic organisms reproduce by sexual and asexual reproduction. Genetic diversity in populations can be strongly dependent on the relative importance of these two reproductive modes. Here, we compare amounts patterns genetic related water hyacinths that differ their propensity for clonal propagation - highly Eichhornia crassipes moderately E. azurea (Pontederiaceae). Our comparisons involved genotype-by-sequencing (GBS) 137 ramets from 60 locations (193,495 nucleotide sites) 118 53...
The doline Buraco das Araras is a peculiar environment and important destiny for ecotourism in the Serra da Bodoquena region, Mato Grosso do Sul, Brazil. Here we describe bat fauna of surrounding areas, report its use as dayroost by Nyctinomops laticaudatus. Bats were mist-netted during two field expeditions, November 2007 January 2008. We captured 153 individuals 10 species, mainly N. laticaudatus (n = 90) Artibeus planirostris 28). This first record region; it was only when leaving dense...
The Cerrado (savanna) is a wide Neotropical formation, but the knowledge on occurrence and distribution of bat species for this phytogeographic region scarce, especially in western portion. Here we address what are their relative abundances site, municipality Sonora, Mato Grosso do Sul, Brazil. Bats were mist-netted eight non consecutive months over course two years. Sampled bats (n = 507) belonged to 18 species. estimator Jackknife 1 estimated 22 species, diversity (H') was 1.6. Richness...

Abstract Understanding the relationships among community structure, vegetation structure and availability of food resources are a key to unravelling ecological processes that biological communities. In this study, we tested (i) whether composition small mammal communities changed across gradients in habitat quality tropical forest fragments, (ii) any observed change could be explained by functional traits species. We sampled 24 trapping grids fragments semi‐deciduous forest, each two 6‐month...
Abstract. Artificial selection and genetic engineering plus an expanding repertoire use of agrochemical inputs have allowed a rapid continuous increase in crop yield (i.e., volume production per unit area) over the last century, which is needed to fulfill food demands from growing human population. However, first signs deceleration stagnation already been reported for some globally important crops. Therefore, study drivers growth its variation essential directing research policies aiming at...
A Bacia do Alto Paraguai (BAP) inclui a planície inundável Pantanal e as áreas altas no entorno que drenam para o rio Paraguai, uma região de transição entre quatro grandes domínios fitofisionômicos da América Sul – Cerrado, Chaco, Amazônia Mata Atlântica. fauna é pobre em endemismos, porém posições central transicional continente conferem enorme riqueza animais vertebrados, oriundos diferentes domínios, especialmente quanto à ordem Chiroptera. Aqui, revisamos espécies morcegos registradas...
