Temporal stability and change in a microgeographical pattern of song variation in the rufous-collared sparrow
(Academic Press Ltd - Elsevier Science Ltd, 2004-09)
We studied the pattern of song variation in the rufous-collared sparrow, Zonotrichia capensis, in the 1987 and 2000 breeding seasons in a 7-km 2 area covering open and closed habitats. We measured 14 quantitative song ...
Temporal variation in richness and composition of recruits in a diverse cnidarian assemblage of subtropical Brazil
(Elsevier B.V.Amsterdam, 2014-11)
Many studies have shown that the processes of colonization of new marine substrata, from settlement to recruitment, can leave long and lasting signals on the richness, composition and general structure of natural epifaunal ...
Phytoplankton community response to hydrological variations in oxbow lakes with different levels of connection to a tropical river
(2013-08-30)
Changes to the structure of the phytoplankton community and to the physical and chemical variables of the water were investigated in oxbow lakes with different levels of connection to a tropical river and subject to annual ...
Macrophyte assemblages in relation to environmental, temporal and spatial variations in lakes of a subtropical floodplain-river system, Argentina
(Elsevier Gmbh, 2016-11)
This work analyses the variation in the structure of macrophyte assemblages in relation to environmental (lake morphometry and water physico-chemistry), temporal and spatial variables, in seven floodplain lakes placed in ...
