We hypothesize that, depending on their sensitivity to artificial light, species can have different activity patterns. The effect of light intensity was tested for several species that we detected in a site area Natura 2000 in the estuary of the Loire. On the edge of the area Natura 2000 This is a central power generation (thermal) and villages, both responsible for a "light pollution" broadcasts.
Sisi hudokeza kwamba, kulingana na unyeti yao kwa mwanga bandia, aina unaweza kuwa na mwelekeo wa shughuli mbalimbali. athari za mwanga intensiteten mara kupimwa kwa aina kadhaa kwamba sisi wanaona katika eneo tovuti Natura 2000 katika kinywa ya Loire. Makali ya eneo Natura 2000 Hii ni kizazi kuu nguvu (mafuta) na vijiji, wote kuwajibika kwa "mwanga uchafuzi" matangazo.
