“…User-friendly tools to calculate suites of hydrologic indices are freely available (e.g., TNC 2009, Konrad 2011), daily time-series of flow data have been collected and continue to be updated for a large number of streams and rivers in the USA (Hirsch and Costa 2004) and abroad (e.g., WCRP 1989), and consolidated, electronic records on the identities and numbers of aquatic species in lotic ecosystems are quickly becoming more accessible (e.g., Schmidt-Kloiber et al 2006, Brosse et al 2013, USEPA 2013. Once enough empirical studies have been done, it will be possible to test for systematic differences among discrete communities and ecosystems, phylogenetic groups, periods (e.g., El Niño vs La Niña years), and biogeographic regions.…”

Hydrologic indices can be used in macroecological models of fish species richness. I used fish distributions and river flow records from 89 river basins in the Pacific Northwest (USA) to identify robust associations between aspects of flow and fish species richness. I calculated 148 hydrologic indices for each basin, created single-predictor regression models for each hydrologic index, and tested for significant relationships between native fish species richness and specific components of flow. I used multiple regression to test the significance and fit of models that combined hydrologic indices that were not highly collinear indices. Significant linear relationships ( p ≤ 0.05) were detected for 85 indices. Coefficients of determination (r 2 ) ranged from 0.04 to 0.33 (median = 0.19, coefficient of variation [CV] = 0.55). I identified 2 multiple-regression models, each including 3 hydrologic indices, as best based on information-theoretic model comparisons. One included median large flood rise rate, CV of 1-d maximum flow, and CV of annual flow. The other included mean annual flow, median high flow timing, and CV of small flood timing. Four major themes emerged from the analyses: 1) fish species richness and a variety of indices of flow magnitude were positively related; 2) the strength of the positive association between fish species richness and flow magnitude was inversely related to flow magnitude and the strongest associations were observed during low-flow winter months; 3) flow variability, indicated by the CVs of hydrologic indices, was negatively associated with fish species richness; 4) indicators of episodic high-flow events (e.g., floods and annual maximum flows) were particularly well represented in the best multiple-regression models of fish species richness. These results can provide a baseline for comparison with other rivers and can be used to help formulate a general, flow-mediated theory of fish species richness in lotic ecosystems.

“…Obviously, for conservation purposes, higher-resolution granularity is required to inform dam site selection in many areas of the globe. To compensate for lack of knowledge in many areas of the world, other mapping efforts have relied on published resources to compile freshwater species lists within regions or basins [63,70]. While these resources can fill in important knowledge gaps, they are coarse (presented at the resolution of large basins) and leave large regions of the globe vacant of information (Figure 9).…”

Accurately mapping freshwater habitats and biodiversity at high-resolutions across the globe is essential for assessing the vulnerability and threats to freshwater organisms and prioritizing conservation efforts. Since the 2000s, extensive efforts have been devoted to mapping global freshwater habitats (rivers, lakes, and wetlands), the spatial representation of which has changed dramatically over time with new geospatial data products and improved remote sensing technologies. Some of these mapping efforts, however, are still coarse representations of actual conditions. Likewise, the resolution and scope of global freshwater biodiversity compilation efforts have also increased, but are yet to mirror the spatial resolution and fidelity of mapped freshwater environments. In our synopsis, we find that efforts to map freshwater habitats have been conducted independently of those for freshwater biodiversity; subsequently, there is little congruence in the spatial representation and resolution of the two efforts. We suggest that global species distribution models are needed to fill this information gap; however, limiting data on habitat characteristics at scales that complement freshwater habitats has prohibited global high-resolution biogeography efforts. Emerging research trends, such as mapping habitat alteration in freshwater ecosystems and trait biogeography, show great promise in mechanistically linking global anthropogenic stressors to freshwater biodiversity decline and extinction risk.

“…The native/translocated/introduced status of each fish species was defined to at least a lake basin-specific level according to the literature (Filipsson 1994, Tammi et al 2003, Kottelat & Freyhof 2007, Brosse et al 2013, Dias et al 2014, Tarkan et al 2015, Boll et al 2016, Trochine et al 2017.

Size diversity and species diversity relationships in fish assemblages of Western Palearctic lakes

Body size, coupled with abundance and taxonomy, may help to understand the mechanisms shaping community structure. Since the body size of fish is closely related to their trophic niche, size diversity (based on individual body size) of fish communities may capture intraspecific variations in fish trophic niches that are not detected by species diversity. Thus, the relationship between size diversity and species diversity may help to integrate variation at both intraspecific and interspecific levels. We studied the relationship between species diversity and size diversity as a measure of the degree of overlap in size among species and thereby the potential overlap in niches in a community. We hypothesized that the relationship between size diversity and species would be different across the European continent due to different levels of size overlap in fish communities. The data were derived from samplings of fish communities using standardised benthic gill nets in 363 lakes. At the continental scale, size diversity increased with species diversity; at the ecoregion scale, the slope of the relation changed across the continent, with the greatest mismatch occurring in northern Europe where communities comprised only one or a few species, but each of which exhibited a great range in size. There was an increase in slope towards the south with significant relations for four out of six ecoregions. The steeper size diversity‐species diversity slope at lower latitudes is attributable to a lower overlap in fish size and thus likely to finer niche separation. Our results also suggest that size diversity is not a strong surrogate for species diversity in European lake fish communities. Thus, particularly in fish communities composed of few species, measuring size diversity may help to detect potential functional variation which may be neglected by measuring species diversity alone.
