“…As there was little variability in the distances between all Fish community structure the other basins, any analysis involving distances would result in the streams on basin 1 having a high leverage value, potentially leading to spurious results. Besides, stronger differences in basin 1 may have also been due to the fact that this was the only basin that drains into the Purus River (the others drain into the Madeira River), a result in accordance with other studies, which have also found differences in ichthyofauna composition between basins that drain into different large rivers (Matthews and Robison, 1988;Carlson and Daniels, 2004;Mendonça et al, 2005;Ingenito and Buckup, 2007). As basin 1 was different both in terms of distance and drainage direction, and there was no replicates for these differences, it was not possible also to analyze the relative effects of distance and drainage direction on composition, and to assess what of these factors would be responsible for the greater differentiation of the basin 1.…”

“…For example, Matthews and Robison (1988) found significant differences in ichthyofauna composition between basins of major rivers in Arkansas. In New York, Carlson and Daniels (2004) observed significant differences in fish species richness and composition between 19 basins that are part of seven drainage systems in the region. Ingenito and Buckup (2007) reported significant differences in ichthyofauna between the Parnaíba do Sul and Sapucaí basins, but little differentiation within these basins.…”

Effects of isolation and environmental variables on fish community structure in the Brazilian Amazon Madeira-Purus interfluve

et al. 2013

Due to the existence of terrestrial barriers to freshwater fish dispersion, it is believed that its distribution is strongly associated with historical factors related to the formation of the habitats they occupy. By the other hand, some studies reveal the influence of abiotic conditions (such as size of water bodies, pH, conductivity) on the composition of fish fauna occurring in small streams. This study aimed to investigate whether drainage basins, because catchment boundaries are potential barriers to fish dispersion, or the physical structure and physico-chemical characteristics of water have a greater influence on fish community structure in small streams. We sampled 22 streams belonging to five drainage basins in the Madeira-Purus interfluve. Fish were caught with dip nets and a small trawl, and data were simultaneously obtained on structural characteristics of the streams and physico-chemical characteristics of the water. Community composition was analyzed using Non-Metric Multidimensional Scaling (NMDS), and variables related to structural and physico-chemical characteristics were summarized by Principal Component Analysis (PCA). Two explanatory models relating faunal composition to environmental factors were constructed: the first using only continuous variables and the second including the drainage basin as a categorical variable. The Akaike Information Criterion (AIC) and AIC weight were used to select the best model. Although structural and physico-chemical variables significantly contributed to explaining faunal composition, the model including the drainage basin was clearly the better of the two models (more than 90% support in the data). The importance of drainage basins in structuring fish communities in streams may have significant consequences for conservation planning in these environments.Keywords: Ichthyofauna, fish ecology, physical variables, chemical variables, western Amazon. Efeito do isolamento e das variáveis ambientais na estrutura de comunidades de peixes do interflúvio Madeira-Purus na Amazônia brasileira ResumoDevido à existência de barreiras terrestres à dispersão de peixes de água doce, acredita-se que sua distribuição é fortemente associada a fatores históricos relacionados à formação dos habitats que ocupam. Por outro lado, alguns estudos revelam a influência de condições abióticas (tais como o tamanho do corpo d'água, pH, condutividade) na composição da fauna ictiíca de rios de pequena ordem. Este trabalho teve como objetivo investigar se bacias hidrográficas, cujo divisor de águas representa uma potencial barreira para a dispersão dos peixes, ou a estrutura física e características físico-químicas da água têm maior efeito sobre a estrutura de comunidades de peixes de riachos de pequena ordem.

“…Most of the species not reported in 1937 may have gained access to the system by migration from downstream sites in recent decades or may have been overlooked in the original survey (Daniels et al 2006). Only seven were introduced exotic species, which is low when compared to other New York watersheds (Carlson and Daniels 2004 Ten species were reported from this basin for the first time (Daniels et al 2006). These include three introduced exotic species and seven species that immigrated into the basin recently or were previously overlooked or misidentified.…”

Fishes of the Conewango Creek basin of the Allegheny River watershed were surveyed in 2004 and 2005. This basin is a part of the extreme northeastern portion of the vast Mississippi River drainage in North America and includes several species on the periphery of their range; many are rare in the state of New York, USA. One goal of the survey was to develop a species list for the system and assess the change in status of species by comparing recent catches to those of a synoptic survey conducted in 1937. We collected representatives of 70 species and three hybrid taxa. Ten of these fishes have not been reported from the system previously. Prior to this survey, 69 species of fish were reported from the basin. We failed to collect representatives from nine of these species. We collected representatives from 16 families, with 26 species in Cyprinidae and 11 in Percidae, the two most speciose families.

“…The canal is also a vector for invasive species in many watersheds from Buffalo to Albany across NYS (Carlson and Daniels 2004), including the JCW where canal water enters from discharge valves and the lower TCW that is connected directly to the canal. Despite the high density of lowhead dams in the TCW (109) compared to that of the JCW (18), disturbance to the natural flow regime may be greater in the main channel of the JCW because of the Lyndonville Dam near rkm 18 that creates an expansive impoundment and impedes fish migration from Lake Ontario.…”

“…Ono et al (1983) remarked that every species may be necessary to keep an ecosystem intact. Notable declines of many native stream fishes in New York State (Carlson and Daniels, 2004;Carlson, 2005;Wells and Haynes, 2006) have increased awareness of the need to pursue conservation for lesser known or imperiled fishes. The conservation of stream fishes is an evolving science and requires assessment of entire fish assemblages on differ-ent spatial scales.…”

Warm water stream fish assemblages (2005) and habitat variables (2004 and 2005) were examined fromMay to September at 108 sites in the Tonawanda and Johnson Creek Watersheds of Western New York. Seventy species and > 27,500 fishes were identified; ~98% were from Families Cyprinidae, Centrarchidae, Catostomidae and Percidae. Data were analyzed at 16 spatial scales using best subsets and backward stepwise multiple linear regression to explore associations between individual fish species ≥9% of total catch and fish assemblage variables [catch per unit effort (CPUE), species richness, Simpson's diversity] with six habitat variables (pool type, maximum depth, substrate size, instream wood, bank cover, aquatic vegetation). CPUE was the only fish assemblage variable related to habitat variables, especially aquatic vegetation and pool type. Only two species (johnny darter, Etheostoma nigrum; round goby, Neogobius melanostomus) were significantly associated with habitat variables. The results reflected inherent difficulties understanding the complexities of habitat use by warm water stream fishes and their assemblages and how to manage them on a broad scale.
