Synopsis of biological data on shortnose sturgeon, Acipenser brevirostrum LeSueur 1818
Information on the biology and populations of the shortnose sturgeon is compiled, reviewed, and analyzed in the FAO species synopsis style and indicates this species exhibits biological and life-cycle differences over its north-south latitudinal range. Expand
A Protocol for Use of Shortnose and Atlantic Sturgeons
This document reviews the most acceptable methods for short-term holding, identification and measurement, tagging, tissue sampling, gastric lavage, and collection using a variety of gear types and establishes a protocol for sampling to establish whether shortnose sturgeon are present in systems where their status is unknown.

Morphological and genetic variation among shortnose sturgeonAcipenser brevirostrum from adjacent and distant rivers
Morphological and genetic variation observed in this study combined with current knowledge of life history attributes of shortnose sturgeon indicate that conservative management decisions are necessary until the patterns and extent of differentiation among populations species-wide can be investigated further.

The Ecological Collapse and Partial Recovery of a Freshwater Tidal Ecosystem
Abstract European settlement of New England initiated a novel disturbance regime that was prolonged, intensifying through time, and spatially widespread. By the mid-20th century, human commercial andExpand
Shortnose Sturgeon and Atlantic Sturgeon in the Kennebec River System, Maine: a 1977–2001 Retrospective of Abundance and Important Habitat
On the basis of two mark–recapture studies, the adult Shortnose Sturgeon population in the Kennebec system was estimated to be 5,117 (95% confidence interval, 4,206–6,279) for the period 1977–1981 and 9,436 (7,542–11,888) forThe period 1998–2000. Expand
Studies on the blood and branchial mucous cells of freshwater and marine alewives (Alosa pseudoharengus)
Lower plasma prolactin levels in the plasma of Lake Michigan fish are probably due to greater usage of the hormone in freshwater, while density of branchial mucous cells was found to be higher in the marine specimens. Expand
