Meat, flour and sugar baits were used on the soil surface and buried to examine species composition of the ant fauna in three separate tropical forests in Brazil, and to control for the effect of the regional faunal pool. ...
Comparação entre peçonhas de víboras do gênero Bothrops da região meridional, com espécies similares do Brasil central, para avaliação do grau de toxicidade (reptilia, serpentes)
(Pontifícia Universidade Católica do Rio Grande do SulPorto Alegre, 2005)
Foram analisadas amostras de veneno em forma de “pool”, extraídos de duas espécies de Bothrops (B. alternatus, B. jararaca). O “pool” regional foi composto de venenos exclusivamente do Rio Grande do Sul coletados de ...
