“…In Britain, a number of studies have documented spatial variation in water temperature behaviour at national (Walling & Webb, 1981), regional (Walling, 1980) and more local (Crisp & Le Cren, 1970) scales, and have described contrasts in temperature behaviour between streams and rivers (Smith, 1979) and between sites within major river systems (Smith, 1975;Boon & Shires, 1976). Attention has also been directed to the study of temporal variation in water temperatures, and diurnal (Macan, 1958), day-to-day (Smith & Lavis, 1975), seasonal (Edington, 1966) and annual (Smith, 1981) fluctuations have been analysed. Many research investigations have, however, been conducted over relatively short time periods, and little analysis and interpretation of longer-term water temperature data have been published for British rivers, despite the initiation of systematic monitoring of river water temperatures in Britain nearly 50 years ago (Herschy, 1965).…”

Despite several studies of spatial and temporal variation in water temperature characteristics, few investigations of longer-term water temperature behaviour in Britain rivers have been undertaken. This paper reports the results from a 10-year study of river water temperatures at three monitoring stations on the River Exe, Devon, UK. Data concerning annual statistics, seasonal regime, diurnal variation, duration characteristics and accumulated temperature are analysed and reveal essentially stable water temperature behaviour over the decade [1974][1975][1976][1977][1978][1979][1980][1981][1982][1983]. Contrasts between monitoring stations are also evident and reflect the effects of regional and more local controls as well as the influence of hydrological factors. In spite of these differences, water temperature behaviour is largely synchronous across this river system. La variationtemporelle de température de l'eau dans une rivière du Devon RESUME En dépit de différents études concernant les variations temporelles et spatiales des températures de l'eau, il y a peu d'études au sujet des changements de température à long terme dans les rivières britanniques. Cet article expose les résultats d'une étude qui s'étend 10 ans en trois endroits sur la longueur de la rivière Exe, Devon, Royaume-Uni. Les données sur les statistiques annuelles des régimes saisonniers, les variations diurnes, les caractéristiques de durée et de la température cumulées sont ici analysées et indiquent un comportement stable des températures de l'eau pour la période 1974-1983, L'étude montre aussi quelques différences entre les trois endroits et il nous indique également l'importance des contrôles régionaux et locaux ainsi que l'importance des facteurs hydrologiques. Malgré ces différences,il est évident que les températures se ressemblent largement d'un bout à l'autre de cette rivière.

“…air temperature, precipitation, direct solar radiation, wind velocity, humidity), streamwater temperatures are influenced by stream size (e .g . stream order or annual discharge), water depth, slope and aspect, amount of riparian canopy cover, and groundwater sources (Bilby, 1984 ;Edington, 1965 ;Kamler, 1965 ;Ward, 1985). Although streamwater temperature generally tracks air temperature (Crisp & Howson, 1982), there is often a time lag (Kamler, 1965 ;Ward, 1985).…”

“…The amplitude of daily variation (daily range) in temperature may also be important (Edington, 1965 ;Kamler, 1965 ;Ward, 1985). Some species have obligate diapause periods which are both induced and broken by temperature cues (Pugsley & Hynes, 1985 ; .…”

We investigated the thermal ecology of three Alaskan streams . Monument Creek (MC) and Little Poker Creek (LPC) are subarctic streams in interior Alaska ; LPC is in a permafrost-dominated valley . Imnavait Creek (IC) is an arctic tundra beaded stream in the northern foothills of the Brooks Range . Water temperatures were recorded with automated dataloggers hourly (LPC) or bi-hourly (MC and IC) . Records for MC extend through almost three entire years, while data from IC (three years) and LPC (one year) represent the majority of the ice-free season . We also collected winter water/ice temperatures from IC (1989IC ( -1990 . Mean annual water temperatures were 1 .

“…Most of the detailed studies that have been made refer to northern rivers (Smith 1968) and small northern streams (Macan 1958;Edington 1966;Crisp & Le Cren 1970;Smith & Lavis 1975), though Harvey (1964) described the temperature of a small upland stream in the southwest. Apart from sets of monthly means given as background information in papers on other topics, there is little information about the water temperatures of streams and rivers in the southern and lowland parts of Britain.…”
