Using RNA-Seq and gene-specific methods to examine salinity-induced gene expression changes in an anchialine shrimp
Meeting Abstract 139.4 Monday, Jan. 7 Using RNA-Seq and gene-specific methods to examine salinity-induced gene expression changes in an anchialine shrimp HAVIRD, J. C.*; HENRY, R. P.; SANTOS, S. R.; Auburn University; Auburn University; Auburn University jhavird@auburn.edu Understanding how organisms respond to environmental variation is critical in order to comprehend how they function in their niches. Taxa […]
Seasonal variation in osmotic and metabolic status of diamondback terrapins
Meeting Abstract 139.5 Monday, Jan. 7 Seasonal variation in osmotic and metabolic status of diamondback terrapins HARDEN, L.A.*; WILLIARD, A.S.; Univ. of North Carolina, Wilmington lah4492@uncw.edu Estuarine ectothermic vertebrates are faced with highly variable, tidally-influenced conditions, and many aspects of their biology reflect their ability to withstand and respond to the challenges posed by this environment. Diamondback […]
