“…Furthermore, differences in sun angle 426 and the longer day lengths that occur later in spring would also promote more rapid heating of 427 lakes in years with later spring ice-off (Shuter et al 2013). These findings of longer springs are 428 contrary to the modelling study by Jansen and Hesslein (2004), which indicated that increases 429 in air temperature would reduce the number of days during spring and early summer when lakes 430 were cool. This extension of the spring period is particularly important for lake trout occupying 431 lakes without pelagic prey fish (Vander Zanden and Rasmussen 1996).…”

15We analyzed monitoring data from small Boreal Shield lakes to understand how 16 variations in air temperature and precipitation affect the phenology and amount of habitat for 17 lake trout (Salvelinus namaycush). Annual air temperatures increased by ~2 ºC (significant in 18 fall and winter). In response, ice-cover was reduced by ~19 d. Despite earlier ice-offs, springs 19 became longer, allowing lake trout longer access to littoral regions when water temperatures 20 were cool. Although summer surface water temperatures increased, the summer did not 21 lengthen. Instead, later spring-warming and fall-cooling of lakes caused summer to shift later in 22 the year, potentially delaying fall spawning. Complete loss of optimal oxythermal habitat volume 23 occurred in all lakes and became more prevalent over time, moreso in the darkest lakes. 24Although air temperatures did not become more variable, several habitat measures did, 25 including mean summer surface water temperatures, duration of ice-cover, timing of ice-off, and 26 minimum volumes of optimal oxythermal habitat. Our results suggest that future warming will 27 impose greater thermal stress on lake trout, but may be tempered by longer springs. 28 29

“…The warming of the inshore surface water of Windermere described up to 2002 by has clearly persisted, with the 3 years of 2003-2005 having the second, third and eighth highest values since records began in 1933. An examination of the potential effects of climate change on fish habitats including that of lake trout, Salvelinus namaycush, in temperate zone lakes by Janssen and Hesslein (2004) noted that the impact of oxygen deficits on habitat availability is influenced by lake trophic status. Consequently, through interactions with oxygen availability the impact of increased temperature in Windermere can be expected to be greatest in its south basin.…”

“…The exclusion of salmonids from the littoral zone due to an increase in water temperature at lake shores (Elliot 1981;Jansen and Hesslein 2004) seems to have occurred in Patagonia during the last 20 yearsto the benefit of P. trucha and the detriment of salmonid fish (Quirós 1991;Aigo et al 2008). Salmonids are usually found both in littoral and limnetic zones, and P. trucha is usually found in the littoral zone (Macchi et al 1999(Macchi et al , 2007Buria et al 2007).…”

The latitudinal extension of southern South America imposes a thermal gradient that affects the structure of marine and freshwater fish assemblages and the biology of the species through direct exposure to the temperature gradients or by means of a web of historical and ecological relationships. We have reviewed biological and ecological data of marine and freshwater fishes from the southern Neotropics, including Patagonia, and report several examples of dependence on temperature, from glacial times to today's climate change. We were able to identify historic and present effects on the diversity of fish assemblages, isolation, southern limits for the distribution of species, and morphological variation among populations. There is a wide range of characteristics that exemplify an adaptation to low temperatures, including biochemical peculiarities, physiological adjustments, and alternative life history patterns, and these appear in both freshwater and marine, and native and exotic fishes. The consequences of stable temperature regimes in both the ocean and thermal streams deserve special mention as these shape specialists under conditions of low selective pressure. At present, habitat use and interactions among species are being subject to changes as consequences of water temperature, and some of these are already evident in the northern and southern hemispheres.
