The EIN is part of the growing number of expert databases available through the National Biological Information Infrastructure . The EIN will be open to all scientists with expertise in all areas relevant to the field of ecology. ESA Sections and Chapters Joining an ESA Section or Chapter is a great way to become more active within the Society. Chapters are regionally based and tend to focus on issues related to their localities. Activities may range from field trips to organizing seminars.
Sections draw members who share interest in a particular area of ecology.
Sections provide a network for members to advance their work in the field. Sections and Chapters also organize and sponsor symposia and workshops at the ESA Annual Meeting. Sections are organized to promote various special interests of the membership. Activities are intended to encourage research, exchange ideas, and facilitate communication between ecologists with similar interests. Any ESA member may join a section by indicating their choice on the membership form and submitting dues.
