Fate of native and introduced seeds consumed by captive white-lipped and collared peccaries (Tayassu pecari, Link 1795 and Pecari tajacu, Linnaeus 1758) in the Atlantic rainforest, Brazil.

We studied the role of white-lipped and collared peccaries (Tayassu pecari and Pecari tajacu) as seed predators and dispersers in the Atlantic rainforest of Brazil. The Atlantic rainforest ecosystem is highly threatened and has experienced dramatic declines in its populations of large mammals. Local extinctions can disrupt essential plant-animal interactions such as seed dispersion and seed predation.

Advisory Committee: A Powerful Tool for Helping Decision Makers inEnvironmental Issues.

/ It has been suggested that the general public should be moreinvolved in environmental policy and decision making. It is important forthem to realize that they will have to live with the consequences ofenvironmental policies and decisions.

Responses of indicator bacteria to forest soil amended with municipal sewage sludge from aerated and non-aerated ponds.

The survival of faecal and total coliform bacteria and Streptococcus faecalis (indicator bacteria) were monitored in experimental plots receiving various amounts of biological or dephosphatation municipal sewage sludge. Biological sludge was applied on coniferous and mixed regenerative forest soils. The results show that except for total coliforms, there was little significant treatment effect on the indicator bacteria numbers in all of the sites.
