Última Bird-habitat associations in coastal rangelands of southern Brazil Iheringia, Sér. Zool. Dias,Rafael A.; Bastazini,Vinicius A. G.; Gianuca,Andros T.. Nearly all remnants of temperate grasslands in southeastern South America are used for livestock ranching and are subject to habitat degradation resulting from this activity. Exploring how habitat features affect the composition of grassland avifaunal communities is a first step to understand how current cattle-ranching management practices impact avian diversity. We used canonical ordination to test for relationships between five habitat variables and the composition of the bird community in coastal grasslands in southern Brazil. We sampled pastures with different heights, from overgrazed short-grass to tall herbaceous vegetation. We recorded 1,535 individuals and 27 species of birds. The first ordination axis indicated a strong contribution of mean...

Zool. Dias,Rafael A.; Bastazini,Vinicius A. G.; Gonçalves,Maycon S. S.; Bonow,Felipe C.; Müller,Sandra C.. Afforestation of temperate grasslands with fast-growing trees for industrial pulpwood production is spreading in South America. Despite high afforestation rates resulting from governmental policies that stimulate pulpwood production in grasslands of southern Brazil and Uruguay, the impact of this activity on biodiversity remains to be properly assessed. We used an Impact-Reference study design to evaluate how grassland afforestation affects the composition of grassland bird assemblages. We sampled eucalyptus plantations and neighboring natural grasslands in southern Brazil from 2006-2009, and relied on nested sampling and analysis to separate the effects of afforestation from the natural variability of grasslands. We recorded a significant difference in... Tipo: Info:eu-repo/semantics/article Palavras-chave: Río de la Plata Grasslands; Pulpwood; Impact-Reference; Eucalyptus; Brazil.
