ECOLOGIA FILOGENÉTICA DE COMUNIDADES DE PEIXES DE RIACHO NEOTROPICAIS

Neotropical stream fishes exhibit a complex evolutionary history and encompass both old and recent lineages. Patterns of species diversity of stream fishes are relatively well-studied for Neotropical streams, but not for patterns of clade distribution and historical factors that structure these assemblages, which are the main interests of phylogenetic ecology. Understanding the evolutionary context of communities provides important insights into large-scale mechanisms that structure them. This review aims to: (i) discuss the main concepts of phylogenetic ecology and its application to Neotropical stream fishes; and (ii) highlight the main methods applied in this background. The first section presents the main phylogenetic hypothesis of fishes and discusses how their gaps in Neotropical stream fishes hinder phylogenetic ecology. Afterward, we discuss the main concepts of phylogenetic ecology (phylogenetic signal, community phylogenetic structure, and phylogenetic diversity), as well as gaps and potential applications of these concepts and tools to understand Neotropical stream fish assemblages. The second section introduces the main methods to address the phylogenetic ecology, including a standardized procedure to edit fish phylogenetic trees, comparative methods, and indices and analytical tools to understand community structure and conservation importance. Finally, we discuss the perspectives to the next years to better understand the Neotropical stream fish assemblages in the light of past and current historical processes.

Stream Fish Assemblages

<em>Abstract</em>.—Stream fish assemblages are influenced indirectly by natural and anthropogenic landscape features acting through intermediate factors like flow and temperature regimes, water quality, and physical habitat. These relationships affect distributions and abundances of individual species and also frame potential interactions among different types of fishes. This hierarchical influence of environmental factors, also known as the landscape perspective, is a widely accepted view of fluvial systems. However, few studies have attempted to quantify the complex mechanistic relationships among landscape variables, intermediate factors, and fish, a gap due partially to limitations of traditional analytical techniques for devolving such relationships. Using covariance structure analysis (CSA), we attempt to quantify the influence of natural and anthropogenic land uses on stream fish assemblages through indirect effects on fluvial physical habitat, including descriptors of habitat complexity, flow stability, and channel size, for 46 streams of southeastern Michigan. CSA was selected for this investigation because of its ability to quantify indirect effects of variables through intermediate factors and to account for intercorrelations among related measures. For analysis, fish assemblages were summarized by their richness and diversity and also according to functional groups that included trophic guilds and preferences for stream size, substrate, and geomorphological units, such as riffles and pools. Our analysis showed that, when acting through habitat factors, assemblages were more strongly influenced by natural landscape features, including catchment area and geology, than by anthropogenic land uses of our study region. Further, the analyses revealed that different aspects of fish assemblages varied with different habitat variables. While diversity and richness increased with habitat complexity and channel size, numbers of carnivores decreased with flow stability, possibly due to the link between flow and stream temperature regimes of our study region. Diversity and richness, however, were not affected by human land uses. Numbers of invertivores, fish preferring fine substrate, and fish preferring pool/ run habitat all increased with agriculture while numbers of detritivores increased with both agriculture and urban land use. These results emphasize complex effects of landscape features on stream fishes through intermediate factors and underscore the importance of understanding the varied response of different aspects of fish assemblages to environmental influences for improved conservation and restoration opportunities.

Stream Fish Assemblages

Groundwater pumping for agriculture is a major driver causing declines of global freshwater ecosystems, yet the ecological consequences for stream fish assemblages are rarely quantified. We combined retrospective (1950–2010) and prospective (2011–2060) modeling approaches within a multiscale framework to predict change in Great Plains stream fish assemblages associated with groundwater pumping from the United States High Plains Aquifer. We modeled the relationship between the length of stream receiving water from the High Plains Aquifer and the occurrence of fishes characteristic of small and large streams in the western Great Plains at a regional scale and for six subwatersheds nested within the region. Water development at the regional scale was associated with construction of 154 barriers that fragment stream habitats, increased depth to groundwater and loss of 558 km of stream, and transformation of fish assemblage structure from dominance by large-stream to small-stream fishes. Scaling down to subwatersheds revealed consistent transformations in fish assemblage structure among western subwatersheds with increasing depths to groundwater. Although transformations occurred in the absence of barriers, barriers along mainstem rivers isolate depauperate western fish assemblages from relatively intact eastern fish assemblages. Projections to 2060 indicate loss of an additional 286 km of stream across the region, as well as continued replacement of large-stream fishes by small-stream fishes where groundwater pumping has increased depth to groundwater. Our work illustrates the shrinking of streams and homogenization of Great Plains stream fish assemblages related to groundwater pumping, and we predict similar transformations worldwide where local and regional aquifer depletions occur.
