Genetic variation at microsatellite loci in sturgeon: Primer sequence homology in Acipenser and Scaphirhynchus
Hierarchical stochastic modelling of large river ecosystems and fish growth across spatio-temporal scales and climate models: the Missouri River endangered pallid sturgeon example
Abstract (from http://sp.lyellcollection.org/content/early/2015/10/09/SP408.11.abstract): We present a hierarchical series of spatially decreasing and temporally increasing models to evaluate the uncertainty in the atmosphere – ocean global climate model (AOGCM) and the regional climate model (RCM) relative to the uncertainty in the somatic growth of the endangered pallid sturgeon (Scaphirhynchus albus). For effects on fish populations of riverine ecosystems, climate output simulated by coarse-resolution AOGCMs and RCMs must be downscaled to basins to river hydrology to population response. One needs to transfer the information from these climate simulations down to the individual scale in a way that minimizes extrapolation...
This dataset describes the diameter, shape, settling velocity, and specific gravity of eggs from 9 female pallid sturgeon and 14 female shovelnose sturgeon as determined in laboratory studies. Pallid sturgeon and shovelnose sturgeon are believed to broadcast demersal eggs in the current, near the river bed over coarse substrate. It is hypothesized that eggs settle immediately following fertilization, but field conditions preclude direct observation. The dispersal of sturgeon eggs is affected by physical properties of the eggs and hydraulic conditions at the spawning location.
A stochastic bioenergetics model-based approach to translating large river flow and temperature into fish population responses: the pallid sturgeon example
Abstract (from http://sp.lyellcollection.org/content/early/2015/05/21/SP408.10.abstract): In managing fish populations, especially at-risk species, realistic mathematical models are needed to help predict population response to potential management actions in the context of environmental conditions and changing climate while effectively incorporating the stochastic nature of real world conditions. We provide a key component of such a model for the endangered pallid sturgeon ( Scaphirhynchus albus) in the form of an individual-based bioenergetics model influenced not only by temperature but also by flow. This component is based on modification of a known individual-based bioenergetics model through incorporation...
This model was based upon expert review, known habitat and known locations of the species. The model can be linked or joined via the "Seg_ID" to the streams layer used in this project. Using the "present" field, the predicted presence locations of the pallid sturgeon can be shown for every stream segment in the known range of the species within the study area. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are fit for the User's intended use. The User is encouraged to carefully consider the content of the metadata file associated...
Habitat Use and Movements of Pallid and Shovelnose Sturgeon in the Yellowstone and Missouri Rivers in Montana and North Dakota
Genetic distinction of pallid, shovelnose, and Alabama sturgeon: emerging species and the US Endangered Species Act
Pallid sturgeon (Scaphirhynchus albus) status data created for the Western Division of the American Fisheries Society (WDAFS)
Pallid sturgeon seasonal habitat selection in a large free-flowing river, the lower Mississippi River, 2009-2015-Data
The data was collected at two lower Mississippi River sites and consists of year round pallid sturgeon Scaphirhynchus albus capture attributes (including habitat type at capture location) from 116 telemetry-tagged fish and habitat area estimation for the sites.
