Abstract A recent increase in the abundance of snook species ( Centropomus spp.) Texas has been generally associated with a broad‐scale warming trend Texas’ inshore waters, closure commercial fishery 1987, and fairly conservative restrictions on recreational catch implemented at same time. Despite this observed abundance, little is known about complex Texas, including uncertainty changes distribution taxonomy, population structure. Here, data from long‐running fishery‐independent FIN ) set...
Abstract Leveraging existing presence records and geospatial datasets, species distribution modeling has been widely applied to informing conservation restoration efforts. Maxent is one of the most popular algorithms, yet recent research demonstrated models are vulnerable prediction errors related spatial sampling bias model complexity. Despite elevated rates biodiversity imperilment in stream ecosystems, application networks lagged, as availability tools address potential sources error...
Nutrient availability in prey items can have important consequences for the growth, reproduction, survival, and recruitment into adulthood of juvenile fish. For young year sturgeon, which are highly dependent on macroinvertebrates as prey, knowing nutritional content across various within their habitats help managers during habitat restoration. The objective this study was to test differences macronutrient composition major invertebrate groups commonly consumed by sturgeon lower Missouri...
Length-weight relationships can be useful tools for assessing fish condition. We developed these equations (W = aLb) wild-caught age-0 (4.1–12.0 cm) Scaphirhynchus sturgeon from eight reaches spanning over 750 river km of the lower Missouri River 2014 to 2017. used nonlinear modeling estimate constant (a) and exponent (b) LW equation each reach assess potential spatial differences. also assessed long-term temporal effects by estimating parameters year at Lexington reach, which is located in...
Abstract The ability of young fish to find and consume food during early life history is an important factor affecting survival recruitment. While dietary assessments for age‐0 Scaphirhynchus sturgeon (shovelnose pallid sturgeon) in the Missouri River, USA have received increased attention over last 15 years, there currently limited information available evaluate long‐term trends prey consumption body condition. To better understand interannual factors early‐life history, we examined...
Understanding potential limiting factors affecting population growth of the endangered pallid sturgeon, Scaphirhynchus albus, is important in upper (UMOR) and lower Missouri River (LMOR) basins. The UMOR upstream several reservoirs generally has more natural habitat features, whereas LMOR downstream these been channelized to support navigation. In both sections, sturgeon recruitment age-1 a concern, but hypothesized for different reasons. One hypothesis centers on food limitation age-0 fish,...
