Modulation and modularity behavioral insights into secondary reduction and loss of the gekkotan adhesive system
Meeting Abstract 88.2 Thursday, Jan. 7 Modulation and modularity : behavioral insights into secondary reduction and loss of the gekkotan adhesive system RUSSELL, Anthony P.*; HIGHAM, Timothy E.; University of Calgary; Clemson University arussell@ucalgary.ca The subdigital adhesive pads of geckos consist of a hierarchy of structural components. The epidermally-derived setae are the ultimate agents of adhesion, but […]

This disc is […]
The regulatory role of sex steroids during primary growth of ovarian follicles of coho salmon (Oncorhynchus kisutch)
Meeting Abstract 87.10 Thursday, Jan. 7 The regulatory role of sex steroids during primary growth of ovarian follicles of coho salmon (Oncorhynchus kisutch) FORSGREN, K.L.*; YOUNG, G.; Univ. of Washington klforsg@u.washington.edu Studies on the endocrine regulation of oogenesis in teleosts have primarily focused on the later (secondary growth: vitellogenesis and maturation) stages of oocyte development. The regulation […]
