Abstract
BackgroundThe composition, structure and biological diversity of two regenerated areas after livestock activities in a Tamaulipan thornscrub vegetation from Northeast Mexico were evaluated. The regeneration of each area was evaluated with the establishment of 12 sampling sites of 50m2. From the data obtained ecological indexes such as: Importance Value Index and Diversity (alpha and beta) were evaluated.ResultsA total of 17 families, 40 genera and 42 species were registered, the most representative family was Fabaceae with 11 spp. The intensive livestock area had 36 species; a Margalef index of 4.44 and a 1.24 Shannon index, while the extensive livestock area had 32 species, a Margalef index of 4.24 and a 2.16 Shannon index. The communities evaluated have a (48%) mean similarity.Conclusions1) Regenerated communities after livestock use showed higher richness of species and alpha diversity.2) Evaluated communities have a mean similarity of (48%). 3) Even after 25 years of regeneration the most dominant species was Cenchrus ciliaris that is used for cattle forage.
期刊介绍:
Revista Chilena de Historia Natural (RCHN) publishes original research dealing with past and present phenomena from organismic to higher levels of biological organization, considering both empirical and theoretical studies on all kinds of taxa and environments.
The major areas covered by RCHN are: botany and zoology; physiological and behavioral ecology; population biology; community and ecosystem ecology; systematics, biogeography and evolution.
