Thermal optima and tolerance in the eurythermic
goldfish (Carassius auratus): relationships between wholeanimal aerobic capacity and maximum heart rate.
incrustans, this species is eurythermic
(--1.6[degrees]-12.5[degrees]C) and euryhaline ([25.6%.sub.o]-[35.5%.sub.o]) (Ereskovsky, 1994b).
Other marine species showing small interoceanic genetic distances include tuna, blue marlin, and green sea turtles, but for these eurythermic
species, unlike sticklebacks, occasional contemporary gene flow through southern oceans is possible (Graves et al.
A half of all species (9) are eurythermic or thermophilic and occur everywhere or widely in Europe except the tundra zone.
Thermophilic, cold-preferring, and eurythermic harpacticoid species occur in Estonia.
We also found evidence of an adaptive mechanism of pressure-temperature interaction in these animals from the eurythermic
habitat of the hydrothermal vents.
In addition, other studies have reported the euryhaline character in the larval (Carvalho et al, 2013) and adult forms (Coelho, 1963, 1964), eurythermic
characteristics (Stilman & Somero, 2000), and the use of different strategies by the species.
In Lake Peipsi the most common stenothermic winter rotifers were Synchaeta verrucosa (Nipkow) and Polyarthra dolichoptera (Idelson); among eurythermic
species, the most frequent were Keratella cochlearis (Gosse) and K.
Bimeria vestita is considered to be cosmopolitan (Ramil & Vervoort, 1992), although without records from the Arctic and Southern oceans (but see Marques et al., 2000), is eurythermic
(16-31[degrees]C), euryhaline (salinity 29.0-36.5; Calder, 1993; Migotto, 1996), and in shallow (<25 m) to deep waters (358 m) (Vanhoffen, 1910, Wedler & Larson, 1986; Marques & Migotto, 2004; Genzano et al., 2009).
When the eurythermic
species behaviour is associated with the geographical distribution the panorama of influences is expanded with ecological, social and genetic factors.
In addition, the number of Tropical, Paulista, and Tropical-Paulista species decreased and the number of wide-distribution eurythermic
species increased in the southwestern Atlantic provinces (Tropical-Paulista-Patagonic species) towards the south (Fig.
* Group A: eurythermic
and euryhaline coastal species such as the cladoceran Pleopis polyphemoides and the chaetognath Sagitta tenuis.
