Physiological and Molecular Responses of Eurythermal and Stenothermal Populations of <i>Zostera Marina</i> L (Eelgrass) to Climate Change
<p>As CO<sub>2</sub> levels in Earth’s atmosphere and oceans steadily rise, varying organismal responses may produce ecological losers and winners. Increased ocean CO<sub>2</sub> can enhance seagrass productivity and thermal tolerance, providing some compensation for climate warming. However, the …

The effect of temperature on the life cycle of Drosophila nebulosa
… of D. nebulosa. D. nebulosa is considered a stenothermal species from a warm environment and has been reported in Texas and Florida, the West Indies, Mexico, Central America, and as far south as Brazil. According to the hypothesis of Hunter (1964), the capacity of this species for adaptation …

Ecophysiology and Food Web Dynamics of Spring Ecotone Communities in the Edwards Aquifer, USA
… indicate that ecotone-associated species exhibit stenothermal tolerance profiles when compared to surface species. I also examined resource use in invertebrate communities at two spring ecotones using stable isotopes of carbon (δ13C) and nitrogen (δ15N) and amino acid-specific stable isotopes …

Effects of annual thermal regime on growth trajectories of native age-0 brook trout (Salvelinus Fontinalis)
… for such changes. Brook trout are considered stenothermal, with a thermal preference of 14°C to 18°C, and a critical thermal maximum of 25°C. With such narrow thermal optima, brook trout are restricted to watersheds with adequate thermal refugia to withstand warm summer temperatures. For …

Is aquatic invertebrate endemism in the Western Cape region of South Africa related to the fynbos blackwaters?
… by low pH and pure, silt-free water. A warm stenothermal group, comprising Leptonema, Elassoneuria and Eatonica spp. is limited to the subtropical regions of South Africa, where water is alkaline. A eurythermal, pH-insensitive group that includes Castanophlebia calida, Ecnomus and …

Reproductive success in Antarctic marine invertebrates
… peak in productivity. As a result of this stenothermal environment, energy input has a profound ecological effect. These conditions have developed over several millions of years and have resulted in an animal physiology that is highly stenothermal and sometimes closely coupled with the …

The Mall Bay Formation (Ediacaran) and the Protracted Onset of the Gaskiers Glaciation in Newfoundland, Canada
… that their predecessors may have evolved under stenothermal cold-water conditions. Rock flour from glacial activity could have acted as fertilizer, amplifying the production of photosynthetic oxygen and the export of bioavailable phosphorus to the seafloor. Overturning of cold surface water, as …

Body Size In Antarctic And Temperate Sea Spiders: The Role Of Temperature And Oxygen
… Antarctic organisms are thought to be highly stenothermal meaning they can only function within a narrow temperature range, but little work has tested if this is true over ontogeny. I tested this idea by measuring the oxygen consumption of larvae, juveniles, and adults of A. glacialis at a …

The Na/K-ATPase in the gills of Antarctic and New Zealand nototheniids: The Physiologic and Molecular Effects of Warm-acclimation.
… acclimation in two Nototheniid species, the stenothermal Antarctic Trematomous bernacchii and the eurythermal New Zealand Notothenia angustata. were investigated by measuring serum osmolality, gill Na/K-ATPase activity, sodium pump density and ouabain affinity. Both fishes were acclimated at …
