Host-specific community structure of tropical sponge microbiomes
Meeting Abstract 108.6 Wednesday, Jan. 7 11:30 Host-specific community structure of tropical sponge microbiomes EASSON, C/G*; THACKER, R/W; University of Alabama at Birmingham; University of Alabama at Birmingham cgeasson@uab.edu Sponges (Porifera) can host diverse and abundant communities of microbial symbionts that make critical contributions to host metabolism. Observations suggest that these microbiomes may be transferred by a […]

Respiratory responses of octopuses to ocean acidification
Meeting Abstract 108-4 Thursday, Jan. 7 09:00 Respiratory responses of octopuses to ocean acidification ONTHANK, K.L.; Walla Walla University Kirt.Onthank@wallawalla.edu http://people.wallawalla.edu/~kirt.onthank/ Cephalopods are active, mobile predators that are physiological convergent with vertebrates, despite using molluscan physiological components. To achieve oxygen loading/unloading dynamics similar to vertebrate hemoglobins, cephalopod hemocyanins exhibit a pronounced Bohr effect. This could potentially lead […]
