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 .
