“…Corroborando a isso MATHEWS et al (1992), observaram também que a distribuição espacial dos peixes foi diretamente afetada pela qualidade da água. ESTEVES & GALETTI JR. (1995), CASTRO & CASSATTI (1997) e BENNEMANN et al (2000 sugerem que esses agrupamentos diferenciais de peixes estão relacionados também, a utilização do recurso espaço e são responsáveis pela partilha entre as espéci-es, sendo que seu uso está associado ao tipo de alimento consumido e o local onde está mais disponível.…”

O objetivo desse trabalho foi a determinação da estrutura populacional da espécie. Foram escolhidos quatro locais de amostragem com características ambientais distintas na bacia do rio Tibagi. As amostragens foram realizadas mensalmente no período de janeiro de 1997 a fevereiro de 1998. Um total de 1553 indivíduos foram capturados, apresentando constância em todos os trechos, com as maiores abundâncias nos trechos do rio Congonhas (76 %). Variações ocorreram entre os trechos por fase de desenvolvimento e classes de comprimento e na distribuição espacial, demonstrando que a espécie apresenta estrutura populacional diferenciada. A espécie apresentou grande capacidade adaptativa exploratória, utilizando estratégias diferenciadas na estrutura da população. A espécie apresentou uma forte tendência ao comportamento r estrategista. O melhor desenvolvimento foi identificado em Congonhas I, talvez devido a existência de condições ambientais favoráveis a manutenção da espécie.

“…Freshwater fish typically rank highly in the trophic system (Moyle and Cech, 2000), and fish distribution is often influenced by environmental variables and habitat characteristics (Matthews and Robison, 1988;Matthews et al, 1992;Kouame´lan et al, 2003;Buisson et al, 2007). In temperate rivers, changes in fish communities are associated with increases in habitat diversity; the relevant factors include stream order and width, altitude, and substrate composition (Belliard et al, 1997;Oberdorff et al, 2001;Grenouillet et al, 2004).…”

-Stream development can generate environmental changes that impact fish communities. In temperate streams, the distribution of fish species is associated with environmental gradients. To analyze the relevant factors, large-scale exploration is required. Thus, to evaluate the distribution patterns of fish in Korea, sampling was conducted on a national scale at 720 sites over a 6-week period in 2009. A total of 124 fish species in 27 families were identified; Zacco platypus and Zacco koreanus of the Cyprinidae were the dominant and subdominant species, respectively. Of the species found, 46 (37.1%) were endemic and 4 (3.2%) exotic; of the latter, Micropterus salmoides and Lepomis macrochirus were widely distributed. Upon canonical correspondence analysis (CCA), both altitude and biological oxygen demand (BOD) were highly correlated with CCA axes 1 and 2, respectively. This explained 62.5% of the species-environment relationship. Altitude and stream order were longitudinally related to species distribution. The numbers of both total and endemic species gradually increased as streams grew in size to the fourth-fifth-order, and decreased in sixth-order, streams. Overall, fish communities were stable throughout the entire watershed, whereas some species showed site-specific occurrence patterns due to the paleogeomorphological characteristics of Korean peninsula. However, various anthropogenic activities may negatively affect fish communities. Therefore, both short-and long-term sustainable management strategies are required to conserve native fish fauna.

“…Ostrand & Wilde (2002) suggested that the assemblage structure is determined more by average or persistent differences in environmental conditions among sites than by seasonal variation in environmental conditions. Matthews et al (1992), comparing large water quality and fish abundance datasets, found spatial distribution of stream fishes of Arkansas to be significantly related to an aggregate of water-quality conditions. Understanding how environmental variables (and their spatial and temporal variations) shape fish community structure is an important issue for environmental managers.…”

Longitudinal patterns of fish assemblages in a large tropical river in southeastern Brazil: evaluating environmental influences and some concepts in river ecology

2008

This study aimed to evaluate environmental influences on fish distribution and to assess the extent to which concepts in river ecology accommodate levels of spatio-temporal heterogeneity of fish assemblages in a 1,080-km long tropical river. A total of 25 sites were sampled between November 2002 and March 2003 in two seasons (summer/wet versus winter/ dry). A thermal gradient separating the upper reaches from the lower reaches was detected. The middle-upper reaches showed higher conductivity and lower dissolved oxygen and pH levels compared with the other reaches. Although some significant associations were found between some fish abundance and environmental variables, the most abundant species (Tilapia rendalli, Geophagus brasiliensis, and Oligosarcus hepsetus) occurred in most sites and under most environmental conditions. Fish community structure varied more in space (longitudinal) than through time (seasonal). The community in the lower reach species was more diverse in comparison with the other reaches. Differences in the fish assemblage structure among the longitudinal river sections appear to have been influenced by the effects of damming, and seem to be partially consistent with the Serial Discontinuity Concept, which views dams as discontinuities within the river continuum. Only the lower river reach showed seasonal differences in the fish community structure, attributable to the influence of flooding. Management plans and biodiversity conservation will benefit by considering the effects of dam disruption and flood increased connectivity to the lotic systems.
