Spontaneous poisoning by Trema micrantha (Ulmaceae) in goats
Hepatotoxic plants are important cause of economical losses in farm animals in Brazil. This report concerns an outbreak of acute hepatic toxicosis, in which seven goats died after consumption of green leaves from a felled Trema micrantha tree. Two of these animals were necropsied and several tissues were processed for histological examination. Main histological finding was observed in the liver...
متن کاملDifferences on post-fire regeneration of the pioneer trees Cecropia glazioui and Trema micrantha in a lowland Brazilian Atlantic forest.
A study of natural post-fire succession was carried out in a disturbed vegetation around fragments of the Atlantic Rain Forest (National Biological Reserve of Poço das Antas (22 degrees 30'-22 degrees 33'S. 42 degrees 15'-42 degrees 19'W), Rio de Janeiro State). All the pre-fire individuals of Cecropia and Trema in the area were numbered with plastic labels. In order to check for the presence o...
متن کاملAbove- and belowground interactions drive habitat segregation between two cryptic species of tropical trees.
In the lowlands of central Panama, the Neotropical pioneer tree Trema micrantha (sensu lato) exists as two cryptic species: "landslide" Trema is restricted to landslides and road embankments, while "gap" Trema occurs mostly in treefall gaps. In this study, we explored the relative contributions of biotic interactions and physical factors to habitat segregation in T. micrantha. Field surveys sho...
متن کاملUso de uma ontologia de lugar urbano para reconhecimento e extração de evidências geoespaciais na Web
Queries that include at least one geographic-related term, such as place names and natural features, are currently a significant subset of the queries that are submitted to search engines. Interest on local information on the Web (local search) is increasing daily, and for this kind of search, the Web is a vast repository of local geographic information. However, traditional search engines have...
متن کاملSeed germination, seedling growth and habitat partitioning in two morphotypes of the tropical pioneer tree Trema micrantha in a seasonal forest in Panama
We examined the distribution, germination, growth and photosynthetic characteristics of two co-existing morphotypes of the pioneer tree Trema micrantha at the Barro Colorado Nature Monument (BCNM), Panama. Morphotypes differed significantly in distribution and in seed characteristics. A ‘large’-seeded morphotype (endocarp mass = 3.83 mg) was associated with treefall gaps in the forest interior,...
