Special Features are intended to address various aspects of a theme that is likely to be of broad interest to ecologists. Ideally, a feature should teach a large audience about an unfamiliar topic or an area in which there has been considerable recent progress, or it should cause the audience to re-examine an issue that is not as settled as most have presumed. Special instructions are available, which explain how to propose and prepare Special Features. A Forum can take a number of forms but always includes a series of commentaries solicited from a number of experts. Special instructions are available for Forums .
Notes are short papers that present significant new observations and methodological advances.
Notes may contain results that are not sufficiently elaborated or developed as to justify an Article, but which are still of considerable potential significance. Submissions must contain no more than 16 manuscript pages . Comments are papers that point out errors of fact or interpretation in, or otherwise comment on, articles that previously appeared in ESA journals, or in articles or books that are the basis of numerous articles published in ESA journals. Submissions must contain no more than 16 manuscript pages. Special procedures have been established for preparation and review of comments and responses to comments.
