Abstract Biological invasion is one of the major components of global change. In the Brazilian Cerrado, the fern Pteridium arachnoideum (neotropical bracken) is a potentially invasive species which is expected to change the vegetation structure of savannas. We assessed effects of the dominance of P.

Oesophageal squamous cell carcinomas (SCCs) may be observed as exophytic masses or ulcerative or infiltrative endophytic neoplasms. However, in cattle, there is also an uncommon gross presentation as an annular stenotic thickening of the oesophageal wall.

Abstract Although certain clonal species are often overdominant in disturbed tropical ecosystems, it is often unclear how this success is related to their patterns of clonal growth and how they respond to abiotic heterogeneity. Here we describe ramet growth and survival in an overdominant Neotropical bracken fern (Pteridium arachnoideum) and assess ...

Abstract Significant chemical differences have been observed among the two neotropical varieties of bracken, caudatum and arachnoideum . Trans - o -hydroxycinnamic acid and coumarin have been found only in the caudatum variety. The concentration changes of ptaquiloside and pterosin B with blade growth were markedly different in caudatum and ...
