the impact of landscape disturbance on spatial genetic structure in the guanacaste tree, enterolobium cyclocarpum (fabaceae).	we examined spatial genetic structure (sgs) in enterolobium cyclocarpum (the guanacaste tree), a dominant tree of central american dry forests in 4 sites in guanacaste province, costa rica. in disturbed dry forest sites (e.g., pastures), e. cyclocarpum is primarily dispersed by cattle and horses, whose movements are restricted by pasture boundaries. the study sites varied in tree densities and disturbance. allozyme analyses of adult trees demonstrated significant levels of sgs in 3 of 4 sites. s ...	2010	19945990
seroepidemiology of toxoplasma gondii (apicomplexa) in meat producing animals in costa rica.	a serologic screening for toxoplasma gondii antibodies by igg indirect fluorescent antibodies test (igg-ifat) was carried among 496 swine and 601 cattle serum samples from throughout costa rica, to study the possible role of their meat in the transmission of the parasite. the overall prevalence of antibodies was 34.4% in cattle and 43.8% in swine. no significant differences were found in the antibody prevalence between males and females in both animal groups, which acquire the infection early in ...	1994	7480936
