Abstract

This study aimed to know the phytosociological composition of the arboreal component in an area of spring in Sirinhaém - PE. Ten plots (10 m x 25 m) were arranged in rays above the springs and distributed systematically in 5 lines, separated by a 45° angle, each. In each line, 2 plots were allocated, at an interdistance of 25 m. In each plot, all individuals with CAP ≥ 15 cm were sampled, which were measured and had the estimated height. The phytosociological parameters were analyzed and an admissible sampling error of 20% and probability level of 95% was adopted. The calculated sampling error was 18%, lower than that established. The spring had a density of 1,236 individuals ha-1, with an estimated basal area of  27,647 m2 ha-1. Tapirira guianensis was characterized by a combination of large numbers of individuals, high dominance and high frequency, demonstrating that it is a species with wide distribution in the area. Regarding the relative frequency, in addition to T. guianensis, Eschweilera ovata and Inga flagelliformis were distinguished. The highest values of absolute dominance were of the species T. guianensis and Virola gardneri. In terms of Importance Value, the highlight was on T. guianensis and V. gardneri.

Ethical Guidelines for Journal Publication

The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles. 

Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.

In particular, 

Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.

Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.

Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
