“…For example, after spawning, the highest densities of small Pecos bluntnose shiner are in downstream reaches, whereas larger adults are more abundant upstream (Bonner, ; Hoagstrom & Brooks, ; Hoagstrom, Brooks & Davenport, ), and a similar pattern is indicated for Sabine shiner (Heins, ). However, recent analysis for Pecos bluntnose shiner appears to support the upstream movement of PBS species, with otolith microchemistry data indicating that 82% of the population migrates upstream while the remaining fish are local residents throughout their lives (Chase, Caldwell, Carleton, Gould & Hobbs, ; Wilde, ). Based on limited understanding of PBS species movements, connectivity through periods of suitable discharge prior to or during the spawning season is anticipated to be important to a large proportion of these populations.…”

“…Isolating fragmentation effects from background landscape changes causing habitat loss can be challenging and has caused contention regarding the threat posed by fragmentation acting alone (Hoagstrom, ; Wilde & Urbanczyk, ). Given the PBS lifestyle, there is little doubt concerning the need for longitudinal connectivity sufficient for the drift and development of eggs through the larvae stage (Bottrell et al., ; Chase et al., ; Moore, ; Platania & Altenbach, ; Souchon, Sabaton & Deibel, ); however, early life stages of PBS species are particularly sensitive to environmental degradation (Wilde & Durham, ) that typically accompanies or is magnified by fragmented connectivity (e.g. dewatering, flow alteration, water pollution, habitat destruction, invasive species; Hoagstrom et al., ).…”

“…The ratcheting mechanism is one explanation for why PBS assemblages do not recover when precipitation‐mediated surface flows are returned to regions historically supported by groundwater flow (Eberle et al., ) or when in‐channel flow is maintained but floodplain inundation and habitat maintenance are compromised (Cowley, ; Galat, Fredrickson & Humburg, ). Thus, because PBS fish populations are regulated and maintained across broad spatial scales (Chase et al., ; Perkin & Gido, ), isolated stream segments containing appropriate habitat can remain vacant if recolonization from distant source populations is not possible (Luttrell et al., ).…”

“…For example, there is evidence that some portion of these populations are recruiting in a limited extent of river (e.g. Chase et al., ), but the responsible factors are poorly understood. Further, nutrient loads have been noted as one factor related to the decline of pelagic fishes and food web changes of the San Francisco Estuary (Glibert, ), but we are unaware of food web examination within Great Plains rivers.…”

The emblematic minnows of the North American Great Plains: A synthesis of threats and conservation opportunities

Anthropogenic changes to the Great Plains rivers of North America have had a large, negative effect on a reproductive guild of pelagic‐broadcast spawning (PBS) cyprinid fishes. The group is phylogenetically diverse, with multiple origins of the PBS mode. However, because of incomplete life‐history information, PBS designation often relies only on habitat and egg characteristics. We identified 17 known or candidate PBS fishes and systematically synthesized the literature on their biology and ecology in relation to major threats to persistence. Research output on an individual species was unrelated to conservation status, but positively correlated with breadth of distribution. The PBS species have opportunistic life‐history strategies and are typically short‐lived (generally 1–3 years) fishes. Many PBS species have truncated ranges showing declines in both distribution and abundance, especially those endemic to the Rio Grande catchment. Fundamental habitat associations are unknown for many species, particularly regarding seasonal shifts and early life stages. Critical thermal tolerances have been quantified for five PBS species and are generally >35°C. Turbidity and salinity changes are linked to responses at multiple life stages, but information is lacking on interactions between water quality and quantity. Hydrologic alteration appears to be a primary threat to PBS species, through complex interactions with landscape fragmentation, and habitat change. We highlight areas where scientific and management communities are lacking information and underline areas of potential conservation gain.

1. Flow intermittence is a major disturbance for riverine fishes. Many species of fishes that evolved in naturally intermittent streams have specialized adaptations to survive drought such as movement to refuge habitats. Conservation of fishes in river systems with highly altered flow regimes requires understanding of how individuals and populations respond to flow intermittence.2. Here, flow was manipulated in two 16-km segments of the Rio Grande, New Mexico, to determine whether managed flow recession could reduce stranding imperilled Rio Grande silvery minnow in isolated pools.3. Slower flow recessions did not decrease stranding in isolated pools over the range tested. Flow recession rate appeared to have an adverse impact on stranding; fewer fish were stranded under faster recession rates, but complex interactions were evident. Fish were stranded throughout both segments regardless of flow recession rate.4. No evidence of a synchronized movement response was observed. Instead, many Rio Grande silvery minnows were probably trapped within proximal habitats, which dry completely and function as evolutionary traps, rather than moving to areas of perennial flow. Use of proximal habitats during streamflow intermittence has implications for management of the species and mitigation of mortality, including managed flow recession rates, and position and function of refuge habitats.5. Effective mitigation for flow intermittence and stranding in streams with highly modified flow regimes will depend on the life history and behavioural response of the species. For Rio Grande silvery minnow, facilitating adaptive behaviour would require creating refuge areas that increase fish survival for weeks to months, as reducing the attractiveness of the traps is likely to be impossible given lack of a synchronized movement response to declining flows. Mismatching life-history strategies, behaviour, and scale of conservation actions may result in ineffective

Documenting fish movement patterns and examining relationships with both fish and habitat characteristics are essential aspects of sound conservation and management. Stream fish movement and habitat use have been associated with a myriad of factors, and variability among individuals is common. Movement and habitat use patterns of juvenile Smallmouth Bass Micropterus dolomieu in streams are poorly understood, particularly for the Neosho subspecies M. dolomieu velox. Our study objective was to determine diel movement patterns and microhabitat use by juvenile Neosho Smallmouth Bass during late autumn. In 2016, we surgically implanted radio transmitters into 13 juvenile Smallmouth Bass in Honey Creek, Oklahoma. We tracked the fish by using radiotelemetry on 41 occasions over the 26-d tag life and located fish throughout the diel cycle to characterize movement and habitat use. Movement patterns varied among individual fish, with cumulative movements ranging from 33 to 1,302 m. Incremental displacement (the distance moved between two consecutive relocations) increased slightly with warmer water temperatures and increasing fish size. Although there was also considerable individual variation in habitat use patterns, deeper habitats were associated with larger juvenile Smallmouth Bass and daytime. Fish also tended to use higher-velocity habitats during the day, and this trend increased over the duration of the study. Our results suggest high individual variation in both movement and habitat use by juvenile Neosho Smallmouth Bass across the diel cycle. We show that juvenile Smallmouth Bass move among microhabitats and would benefit from management actions that maintain and promote instream habitat complexity. Future efforts focused on juvenile Smallmouth Bass movement over longer time periods would be beneficial for understanding movement and habitat use dynamics across a greater range of seasonal and environmental variability.
