ENVIRONMENTAL PARAMETERS. ‌‌ Because we did not perform type-specific but site- specific analyses, impact assessment at broad spatial scales requires the consideration of environmental variables that are not modified by human activities and could well describe community structure. An efficient control of natural ecological patterns known to determine the variability of fish communities across sites is then needed. Hence, the variables given in Table 5 were included in the models. Maximum depth (Zmax) and Lake Area (LA) are strong drivers of fish species richness (▇▇▇▇▇▇▇ and ▇▇▇▇▇ 1974; ▇▇▇▇▇ et al. 1986). Altitude (Alt) parameter can be related to isolation and climatic data (▇▇▇▇▇▇▇ et al. 1998; ▇▇▇▇▇ et al. 1991; ▇▇▇▇▇▇▇▇ et al. 1998; ▇▇▇▇ et al. 1990). No mountain lakes above 1500m were included because species richness is generally low; moreover, in these lakes, fish communities are generally strongly influenced by human introductions (Argillier et al. 2002) and fish is not considered as a relevant bioindicator to assess ecological status (Ministère de l'Ecologie et du Développement Durable, 2006). Catchment area (ADB) can be considered as a surrogate for habitat diversity upstream from the lake (Irz, Argillier et al. 2004). January to December mean yearly air temperatures (TJanuary & TDecember) were obtained from the climate CRU model (New et al. 2002). January and July mean temperature allowed to derive the following independent variable related to temperature requirements of living organisms (Daufresne and ▇▇▇▇ 2007; ▇▇▇ et al. 2007; ▇▇▇▇▇ et al. 2008; ▇▇▇▇▇▇▇, ▇▇▇▇▇ et al. 1999). (i) AveT = (TJanuary _ TDecember)/12 (ii) AmpT = TJuly - TJanuary The geology (G) represents one of the ground characteristics of the Lake catchment area and is defined as calcareous or siliceous. Therefore it relates to the water chemistry and buffering capacity (▇▇▇▇▇▇▇▇▇, Baccante et al. 1985; ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇ et al. 2006). Consequently, this parameter is influencing lakes’ productivity, i.e low specific richness in lakes with low pH (Koskenniemi et al. 1990; ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇ 1988 ; ▇▇▇▇ & ▇▇▇▇▇▇ 1986). At a local scale, this parameter could also influence the nature of the species present (▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ 1983). These parameters were also retained because of their availability (for example mean depth was excluded because of too many unknown values). The square parameters of all environmental variables were also added in the model because of the polynomial character of the response. Maximum dep...
