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 threat posed by invasive non-native species worldwide requires a global approach to identify which introduced are likely pose an elevated risk of impact native and ecosystems. To inform policy, stakeholders management decisions on threats aquatic ecosystems, 195 assessors representing 120 assessment areas across all six inhabited continents screened 819 from 15 groups organisms (freshwater, brackish, marine plants animals) using the Aquatic Species Invasiveness Screening Kit. This...
Abstract Brazil is a megadiverse country and participant of fundamental environmental agreements for biodiversity conservation. However, the internal politics cultures that affect negatively ecological integrity in Brazilian freshwater need to be improved on condition sustainable management. Scientific community, government stakeholders are constant conflicts goals. Meanwhile, current model aquaculture shows problems impact due lack appropriated planning legislation aquatic biota. The...
Abstract Body size is a key trait in ecology due to its influence on metabolism and many other life‐history traits that affect population community responses environmental variation as well ecosystem properties. The spectrum represents the relationship between abundance (or biomass) body size, independent of species identity. Size parameters, such slope or intercept, have been applied extensively indicators ecological status across multiple types. GLOSSAQUA dataset includes data from mainly...
The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for fishes. Our NEOTROPICAL FRESHWATER FISHES data set is to produce a large-scale inventory, covering entire from Mexico and Caribbean in north southern limits Argentina, Paraguay, Chile, Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, represented by occurrence abundance data. number of species numerous orders are as follows: Characiformes...
The aim of the present study was to evaluate spatial patterns in composition, structure and distribution fish assemblages their relationships with abiotic characteristics three urban streams Maringa city, Parana, Brazil. Fish were collected along longitudinal gradient by electrofishing May November 2004. Temperature, nitrogen, pH, oxygen phosphorous influenced at most principal components analysis (PCA). Richness, evenness, Shannon-Wiener index first axis detrended correspondence (DCA)...
O objetivo do presente estudo foi avaliar padrões espaciais na composição, estrutura e distribuição das assembléias de peixes suas relações com características abióticas em três córregos urbanos da cidade Maringá, Paraná, Brasil. Peixes foram coletados ao longo um gradiente longitudinal utilizando pesca elétrica nos meses maio novembro 2004. Temperatura, nitrogênio, pH, oxigênio fósforo as variáveis que mais influenciaram a análise componentes principais (CPA). Riqueza, eqüitabilidade,...
Studies on fish assemblages in streams point out, that understanding the relationship between species and their environment is crucial for conservation. The present study aimed at evaluating effects of changes abiotic variables composition structure Neotropical urban from southern Brazil with different levels urbanization. showed significant differences along urbanization gradient observed streams. Tolerant non-native were found more urbanized sites. A matrix correlation revealed a spatial...
The development of agriculture allowed humans to congregate in settlements which developed into the modern urban societies. This urbanization process caused profound habitat changes, giving rise ecosystems where structure, functioning and dynamics ecosystem are determined by human activities. Despite increasing rates worldwide,the ecology is poorly known. In this chapter, we focus on stream expose current advances fish ecology. We explore topics concerning biodiversity,ecological...
The process of urbanization profoundly changes aquatic ecosystems. Urban streams often have flashier hydrology, increased nutrient and contaminant concentrations, reduced biodiversity when compared with nonurban streams. Collectively, these characteristics are described as the urban stream syndrome (USS). USS is traditionally attributed to discharge large volumes stormwater into streams, thus pointing primary driver degradation. However, was developed using evidence from studies in...
This study evaluated the diet and feeding selectivity of catfish Imparfinis mirini in streams with different degrees urbanization effect rainfall on availability prey. The was based especially Chironomidae Trichoptera. Significant spatial differences were found between streams; fish similar rural peri‐urban streams, differed from that urban stream. Seasonality an unimportant factor affecting species' diet, which did not differ significantly rainy dry periods any streams. Fish stream fed more...
The European catfish, Silurus glanis is one of the largest freshwater fish worldwide. Although it originally inhabited rivers Eastern Europe and Western Asia, this species spreading within Europe, due to its popularity among anglers interest in as a potential for aquaculture. This has never been recorded America until now. In August 2006, State Santa Catarina, Southern Brazil, local newspaper “Diario Catarinense” reported, with photograph, capture huge catfish by an amateur fisherman...
The metropolitan area of Maringá, Paraná state (southeastern Brazil), has many small headwater streams that are affected by urban development. Checklists fish species in these sites important tools to learn about the biodiversity impacted environments. Samples were taken every two months from July 2007 June 2008 three different along 10 Maringá city within a gradient urbanization. A total 38 ascribed six orders, 12 families, and 27 genera collected, including non-native species, 14 probably...
