Abstract Protecting riparian vegetation around streams is vital in reducing the detrimental effects of environmental change on freshwater ecosystems and maintaining aquatic biodiversity. Thus, identifying ecological thresholds useful for defining regulatory limits guiding management zones towards conservation biota. Using nationwide data fish invertebrates occurring small Brazilian streams, we estimated native loss which there are abrupt changes occurrence abundance bioindicators tested...
The Porto Murtinho Pantanal lies at the limit of Upper Paraguay River basin, and despite its biogeographical importance, several aspects ecology fish assemblage are not known. Monthly samples associated with aquatic macrophytes were taken from February 2009 through January 2011. A total 46,327 individuals collected, belonging to 144 species. Characiformes Siluriformes predominant orders, Odontostilbe pequira, O. paraguayensis Bryconamericus exodon most abundant Two species, Cynopotamus sp....
A vegetação em Mato Grosso do Sul sofreu grandes mudanças devido à expansão agropecuária desde 1985, que resultou na perda de 1,2 milhões hectares vegetação. Embora existam estudos sobre a modificação da paisagem, eles geralmente se concentram biomas específicos ou usam diferentes métodos análise, dificultando comparações abrangentes.Investigamos como as no uso terra áreas transição afetaram estrutura vegetal ao longo tempo. Para tal investigação, utilizamos dados MAPBIOMAS, para os períodos...
<title>Abstract</title> Climate change is considered a driver for the spread of invasive alien species (IAS); nevertheless, research assessing this link remains limited. Recognizing suitable habitats where IAS have been introduced crucial biodiversity conservation and ecosystem management. Here, we integrated online, museum, laboratory occurrence databases with local ecological knowledge (LEK) on fishes from semi-structured interviews georeferenced Instagram posts traditional recreational...
Abstract The factors effecting fish species richness, evenness and relative abundance in 19 floodplain lagoons the Pantanal (Brazil) were examined. Richness strongly correlated with lagoon's: (i) isolation time from main river; (ii) depth; (iii) distance river. Abundance of five dominant was mainly with: (a) macrophyte cover; (b) (c) piscivore abundance. These results suggest that select to avoid or minimize their confinement inappropriate habitats. A combination strategies, together...
The fish communities of lagoons in the Nhecolândia Pantanal were studied to determine factors which are responsible for composition and abundance species. Fishes collected 19 during August 1997, after their isolation from River Negro, using beach seines (15 × 1.5 m; 2 mm mesh). A total 51 species collected. In lagoons, or parts with dense macrophytes, a screened box trap was used. Fishing also accomplished hooks several sizes. Species richness estimated by jack‐knife procedure, adjustment...
Forensic entomology is a science that uses insect fauna as tool to assist in criminal investigations and civil proceedings. Although the most researched insects are Diptera Coleoptera, ants may be present all stages of decomposition. The aim this study was evaluate role their action on blow flies during decomposition process. Experiments were performed which four pig carcasses exposed cold dry season (November/2012 March/2013) hot wet (May/2013 August/2013). Flies first detect interact with...
Understanding how assemblages are structured in space and the factors promoting their distributions is one of main goals Ecology, however, studies regarding distribution organisms at larger scales remain biased towards terrestrial groups. We attempt to understand if structure stream fish metacommunities across a Neotropical ecoregion (Upper Paraná—drainage area 820,000 km2) affected by environmental variables, describing natural gradient, anthropogenic impacts spatial predictors. For this,...
We have been able to discriminate different castes and sexes of ants in the same colony by measuring cuticular hydrocarbon levels with Fourier transform infrared photoacoustic spectroscopy, compared canonical discriminant function analysis. now applied this methodology various colonies two species genus Ectatomma Brazilian Cerrado. There were clear interspecific differences hydrocarbons these ants, a small intraspecific variation. The between greater E. brunneum than vizottoi. Genetic among...
AIM: The present study analyzed the spatial variation in fish species richness and composition streams of Ivinhema River basin, Upper Paraná determining relationship between local regional descriptors assemblage organization; METHOD: From 2001 to 2011 we sampled 200 stream stretches, using different sampling methods. Local were univariate multivariate methods detect patterns RESULTS: We identified 111 streams, estimated occurrence 117 (CIα0.05 = 123) with lower headwater compared parts...
Length–weight relationships (LWR) were estimated for 17 species and total length at first maturity (L50) three of freshwater fishes from the Miranda River, southern Pantanal, Brazil. The b values compared some in Paraguay River basin with northern (Cuiabá River) part basin; differences length–weight significantly different Pseudoplatystoma corruscans, P. reticulatum (syn. fasciatum). First references on L50 LWR are presented two eight fish species, respectively, as well new maximum species.

AIM: This study aimed to evaluate influence of hydrological variation, ontogeny and interspecific variation in the feeding activity diet composition for P. nattereri S. marginatus floodplain Negro River, South Pantanal. METHODS: The samples were taken with use gillnets cast nets different sizes, from October/2005 August/2008. RESULTS: We sampled 748 specimens, 442 306 marginatus. identified 31 items dry 14 flood season nattereri, 29 eight For both species, fish was predominant food item...
Abstract The objective of this study was to provide a comprehensive list the fish fauna headwater streams Miranda River in Upper Paraguay Basin. Our primary data set constructed from sampling using rectangular sieve, trawl, and gill nets 2004 2015. secondary were derived published reports conducted Basin, addition taxonomic distribution other studies basin. All compiled, which end encompassed period 1999 datasets yielded total 143 species, 104 (72.7%) 39 (27.3%). Species distributed among...
Mashing is an enzymatic procedure for the extraction of sugars from malt. It has strong temperature dependence, so monitoring sugar production very important optimization brewing process. In this work, Fourier transform infrared spectroscopy (FTIR) was used to monitor three different mashing programs. These all presented high concentrations maltose and dextrin, enabling their differentiation according FTIR absorption bands at 991 1022 cm−1, characteristic respectively. The intensities these...
Ecological literature offers a myriad of methods for quantifying β diversity. One such method is determining BDtotal (BD), which, unlike other methods, can be decomposed into meaningful components that indicate how unique sampling unit regarding its composition (local contribution) and species occurrence in the community (species contribution). Despite this advantage, original formulation BD metric only assesses taxonomic variation neglects important dimensions biodiversity. We expanded to...
