“…These accounts suggest a requirement for flowing water in or near spring outflows. In contrast, Kollaus and Bonner (2012) found that in the Devils River, D. diaboli more frequently inhabited deeper pools rather than swift-flowing water. Further, D. diaboli seemed more eurythermic than previously reported.…”

“…Suboptimal conditions can reduce overall performance (Fry, 1967), including swimming and spawning (Reynolds, 1977). Previous studies (LopezFernandez and Winemiller, 2005;Fries and Gibson, 2010;Kollaus and Bonner, 2012) showed that D. diaboli were found in water temperatures from 18 to 318C, and having thermal maxima of 32.6-37.88C. These thermal maxima are quite similar to Lepomis, Gambusia affinis, Cyprinella lutrensis, and M. salmoides (Carveth et al, 2006), fish typically considered to be generalists.…”

“…In a single collection, Garrett et al (2004) Current ideas about the habitat needs of D. diaboli should be expanded. Although it has been common to suggest that these minnows are associated with channels of fast-flowing, spring-fed water over gravel substrates (Harrell, 1978;Cantu and Winemiller, 1997), work in the Devils River (Kollaus and Bonner, 2012) suggested that D. diaboli more frequently inhabited deeper pools and were frequently found in backwater habitats with extreme temperatures. Our data confirmed that D. diaboli can use still-water habitats with heavy vegetation, silt bottoms, and fluctuating temperatures, at least temporarily in times of low to no stream flow.…”

“…Further, D. diaboli seemed more eurythermic than previously reported. The study by Kollaus and Bonner (2012) indicates less dependence on flowing water, which may be critical for persistence during drought. Aside from temperature and flow, other water-quality needs have been noted but poorly explored (Edwards, 2003;Robertson and Winemiller, 2003;Garrett et al, 2004;Phillips et al, 2011;Kollaus and Bonner, 2012).…”

“…Current knowledge of habitat requirements is insufficient to allow predictions of how the Pinto Creek population of D. diaboli might respond to changing water quantity and quality as reports of basic habitat requirements (Harrell, 1978;Cantu and Winemiller, 1997;Kollaus and Bonner, 2012) are somewhat conflicting. Until recently, the presumed habitat requirements of D. diaboli have been aquatic macrophytes (e.g., Justicia americana) associated with fast-flowing, spring-fed, gravel-cobble channels (Harrell, 1978;Cantu and Winemiller, 1997).…”

Fish populations may be isolated via natural conditions in geographically separated ecoregions. Although reconnecting these populations is not a management goal, we need to understand how these populations persist across landscapes to develop meaningful conservation actions, particularly for species occupying sensitive karst ecosystems. Our study objective was to determine the physicochemical factors related to the occurrence of four spring‐associated fishes. Arbuckle Uplift and Ozark Highlands ecoregions, USA. We used a hierarchical approach to identify habitat relationships at multiple spatial scales. We collected detection data using snorkeling and seining. We examined the physicochemical relationships related to the detection and occurrence of four spring‐associated fishes using occupancy modeling in a Bayesian framework. We found physicochemical relationships that differed and were similar between ecoregions for several fishes. For three species, we found different water temperature relationships between ecoregions. Smallmouth bass were ubiquitous in their use of drainage areas in the Ozark Highlands but only associated with the lower network of the Arbuckle Uplift. There were several mirrored relationships between ecoregions, including an interaction between residual pool depth and water temperature, where sites with deeper pools were more likely to be occupied during warmer water temperatures. There were single‐species occurrence relationships with percent vegetation and percent agriculture. Lastly, snorkeling was a more efficient sampling method compared to seining for all fishes. Our results indicate stream temperature mitigation may be possible via the maintenance of key channel morphologies, and we identify shared stressors between ecoregions. Channel mitigation to maintain reaches with deeper pools may be an important strategy for maintaining thermal refugia, particularly when considering climate change. Identifying the mechanistic underpinning of other multiscale ecological relationships would be helpful to discern if some of the different ecoregion relationships represent warning signals or interactions with unmeasured biotic or abiotic factors.

Aquifers and spring complexes within the arid and semi‐arid karst Edwards Plateau region of Texas are evolutionary refugia supporting a large number of endemic flora and fauna. Spring fishes, many of which are endemic, are associated with the spring complexes, whereas river fishes generally avoid spring complexes. Purposes of this study were to experimentally test affinities of spring fishes and river fishes for spring complexes and rivers among six independent spring‐river systems of the Edwards Plateau and to quantitate relationship among spring fishes, river fishes and spring flow magnitude within spring complexes. We found that spring fishes did not exclusively use spring complexes but were more abundant in spring complexes than rivers and that species richness, relative abundance, and density of spring fishes were directly related to spring flow magnitude. Patterns in affinities for river fishes were less distinct. Quantitation of fish–habitat relationships will assist efforts in conserving aquatic resources within the Edwards Plateau and provides predictive models to assess biological integrity of other spring complexes. In addition, consistency in distributional patterns of spring and river fishes provides a framework for testing underlying processes of species segregation and diversification, establishes boundaries of aquatic evolutionary refugia, and expands the value of evolutionary refugia from historical refugia to contemporary and future refugia for Edwards Plateau aquatic biota.
