No effects of drought on the most abundant small Passerine birds in Wetlands of semiarid landscapes

Drought is a widespread event chiefly given in areas and regions submitted to a high temperatures and small rainfall as for example wetlands immerse in arid and semiarid landscapes. Climate change is involving considerable territories and likely limits further expansions of water bodies.1,2 In these sectors, wetlands and other wet spaces depend properly of hydrological regimes which are submitted to strong cyclic seasonality. This cyclic seasonality, altered by climate change, is influencing directly the full biodiversity of the fauna and flora of wetlands.3 Fluctuations in flood degrees can provide restrictions of frameworks that run its communities as diversity, eveness, specific turnover, etc4,5 or can provide contractions in the breeding success of birds but no its complete block.6
