Physiological and life history responses in a mayfly (Callibaetis floridanus) inhabiting ponds with saltwater intrusion

FRONTIERS IN ECOLOGY AND EVOLUTION, 11.

By: J. Cochran n, D. Funk* & D. Buchwalter n

author keywords: mayfly; saline adaptation; ion fluxes; saltwater intrusion; plasticity
TL;DR: Analysis of life-history outcomes and physiological plasticity in a population of Callibaetis floridanus from a coastal pond that routinely experiences saltwater intrusion suggests that saline adapted C. floridas may be more energetically challenged in dilute conditions, which differs from previous observations in other mayfly species.

Respirometry reveals major lineage-based differences in the energetics of osmoregulation in aquatic invertebrates

JOURNAL OF EXPERIMENTAL BIOLOGY, 226(20).

By: J. Cochran n, C. Banks* & D. Buchwalter n

author keywords: Aquatic invertebrates; Salinity; Metabolic rate; Aquatic insects; Calcium; Ion transport
TL;DR: It is shown here for the first time that metabolic rate was unchanged by salinity in the aquatic insects, whereas ion transport rates were positively correlated with higher salinities, which potentially implicates the cost of calcium uptake as a driver of increased metabolic rate under dilute conditions in organisms with calcified exoskeletons.
