“…In warm, oxygen-limited habitats, as found during dry years and in OCH, Fathead Minnow is one of the few species that could provide a predation buffer for Topeka Shiners. One study documented Topeka Shiners establishing territories on the periphery of Fat-head Minnow nests (Stark et al 2002), suggesting they are "nest associates" of Fathead Minnow in addition to Green Sunfish and Orangespotted Sunfish. They also observed groups of Topeka Shiners overwhelming nest-guarding male Fathead Minnow and feeding, presumably, on Fathead Minnow eggs.…”

Our goal was to identify habitat, fish species, and fish assemblages associated with the occurrence of Topeka Shiners Notropis topeka in stream and off-channel habitat (OCH) of west-central Iowa. Fish assemblages and habitat characteristics were estimated in 67 stream and 27OCHsites during 2010-2011. Topeka Shiners were sampled in 52% of OCH sites, but in only 9% of stream sites, which supports the hypothesis that OCH is an important component of their life history. Fish assemblages containing Topeka Shiners were different from those that did not contain Topeka Shiners in OCH sites, but this was not evident in stream sites. Results from logistic regression models suggested that Topeka Shiner presence was associated with increased submerged vegetation and abundance of Fathead Minnow Pimephales promelas. Contrary to the findings of other studies, the abundance of large piscivorous fishes was not associated with the occurrence of Topeka Shiners. Our results provide new information about the biology and life history of the Topeka Shiner that will guide habitat restoration and other recovery efforts.

“…Consistent with this interpretation, observations of spawning in the wild (Stark et al 2002) indicate that Topeka shiner males will often shepherd select females into their territories; presumably, the selected females are the ones most apt to engage in spawning. Here, with heightened GSIs, females might be more readily identified as potential mates, prompting males to scale back their territorial defence.…”

“…Male Topeka shiners establish spawning territories from late May to mid-July (Pflieger 1997). When they are ready to spawn, shiner females enter these territories, are courted, and then release eggs into the water column alongside the male (Stark et al 2002). The fertilised ova then settle to the bottom where they adhere to the substrate (James Candrl, personal communication).…”

Substrate choice of territorial male Topeka shiners (Notropis topeka) in the absence of sunfish (Lepomissp.)

Topeka shiners (Notropis topeka), an endangered minnow species, typically spawn on or around breeding Lepomis sunfish (Centrarchidae) nests. Why spawning Topeka shiners are attracted to these nests is unclear, but having the nesting sunfish provide shiner eggs with improved aeration, a lessening of siltation, and protection from egg predators are possibilities. We tested the substrate utilisation of Topeka shiners in outdoor tanks in the absence of sunfish to determine the shiner's fundamental choice. Shiners were provided with substrate patches of cleaned sand, small gravel, large gravel, and small cobble, and the bare floor of the tank. The substrate above which a male shiner established his territory was used as evidence of choice. A statistically significant choice for sand substrates was demonstrated. This fundamental choice might influence which sunfish nests Topeka shiners use, given that nest substrate characteristics differ both between sunfish species and within species by spawning site location.

“…The CASM TS is a version of the comprehensive aquatic system model (e.g., Bartell et al 2013Bartell et al , 2018Nair et al 2015) that was adapted to provide a food web-ecosystem context for the TS-IBM (Schmolke et al 2019). The CASM TS includes multiple representative populations of aquatic plants and consumers informed by previous Midwestern stream modeling (Bartell et al 2013;Nair et al 2015) and descriptions of Topeka shiner fish assemblages (e.g., Stark et al 2002;Bakevich et al 2013). Daily values of biomass (g C/m 2 ) are simulated for each modeled population based on bioenergetics-based differential equations (Hanson et al 1997;Duffy 1998;Bakevich et al 2013;Bartell et al 2013;Deslauriers et al 2017).…”

A hybrid model was used to characterize potential ecological risks posed by atrazine to the endangered Topeka shiner. The model linked a Topeka shiner individual‐based bioenergetics population model (TS‐IBM) to a comprehensive aquatic system model (CASMTS) to simulate Topeka shiner population and food web dynamics for an Iowa (USA) headwater pool. Risks were estimated for monitored concentrations in Iowa, Missouri, and Nebraska (USA), and for monitored concentrations multiplied by 2, 4, and 5. Constant daily atrazine concentrations of 10, 50, 100, and 250 µg/L were assessed. Exposure–response functions were developed from published atrazine toxicity data (median effect concentrations [EC50s] and no‐observed‐effect concentrations). Two toxicity scenarios were developed: the first included sensitive and insensitive species of algae, and the second reduced algal EC50 values to increase atrazine sensitivity. Direct and indirect effects of atrazine on Topeka shiner prey were modeled; direct effects on Topeka shiner were not assessed. Risks were characterized as differences between population biomass values of 365‐d baseline and exposure simulations. The results indicated no discernable food web effects for monitored atrazine concentrations or constant exposures of 10 µg/L on Topeka shiner populations for either toxicity scenario. Magnified monitored concentrations and higher constant concentrations produced greater modeled indirect effects on Topeka shiners. The hybrid model transparently combines species‐specific and surrogate species data to estimate food web responses to environmental stressors. The model is readily updated by new data and is adaptable to other species and ecosystems. Environ Toxicol Chem 2019;38:2243–2258. © 2019 SETAC.
