Sturgeons (Pisces: Acipenseridae); threats and prospects
Journal of Fish Biology, 1990Life histories of 24 species of sturgeons are briefly summarized and threats to their existence are reviewed. The most important of these are fishing and physical disturbance of rivers (barriers; fluctuating water levels; gravel extraction). Conservation measures to limit and compensate for these impacts are reviewed.

The hypothalamo-hypophysial system in Acipenseridae
Cell and Tissue Research, 1976The proximal neurosecretory contact region (PCR) of Acipenseridae, a homologue of the tetrapod median eminence, has been studied by light, fluorescence and electron microscopy. It occupies the rostral and chiefly the ventral surfaces of the hypothalamic tuber cinereum.

The Hypothalamo-Hypophyseal System in Acipenseridae
General and Comparative Endocrinology, 1997Abstract The regeneration of the hypothalamo–hypophyseal system (HHS) has been studied in the sterlet following hypophysectomy (HypoX). Significant portions of non-apeptide and corticoliberinergic (CRH) neurosecretory cells (NSCs) underwent degeneration.

Osteology and phylogenetic interrelationships of sturgeons (Acipenseridae)
Environmental Biology of Fishes, 1997Sturgeons (Acipenseridae) are an ancient and unique assemblage of fishes historically important to discussions of actinopterygian evolution. Despite their basal position within Actinopterygii, rigorous comparative morphological studies of acipenserids have never been made, and most ideas about acipenserid evolution hinge on an untested impression that ...
