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.

墨西哥塔毛利潘荆棘灌丛两个畜牧后区植物组成和结构

研究了墨西哥东北部塔毛利潘刺灌丛植被在家畜活动后的两个再生区组成、结构和生物多样性。通过建立12个50平方米的采样点来评估每个区域的更新情况。根据所获得的数据，对重要值指数和多样性(α和β)等生态指标进行了评价。结果共有17科40属42种，最具代表性的是豆科11种，集约化畜牧区36种;马格莱夫指数为4.44，香农指数为1.24，而粗放区共有32种，马格莱夫指数为4.24，香农指数为2.16。结论1)家畜利用后再生群落的物种丰富度和α多样性较高;2)评价群落的平均相似度为(48%)。3)即使经过25年的更新，最优势的种仍然是用于牛饲料的毛缕草。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
