Alaska Carbon Cycle

Guest Editors: A. David McGuire and Zhiliang Zhu
Ongoing warming of ecosystems in Alaska has the potential to release carbon to the atmosphere and coastal waters through (1) exposing and mobilizing the large quantity of carbon stored in permafrost soils and (2) emissions associated with potentially more frequent and severe fires. However, other ecological pathways in the carbon cycle could counter this carbon release. The papers in this Invited Feature provide a synthesis of the Alaska carbon cycle through analyses of driving factors and carbon dynamics for uplands, wetlands, and inland waters in the state. The Invited Feature also explores the implications for climate policy and management of carbon at local to international scales. Photo Credit: U.S. Geological Survey/photo by Mark Dornblaser.

Acoustic Telemetry in Fisheries Management

Guest Editors: Glenn T. Crossin and Steven J. Cooke
This Invited Feature highlights the use of acoustic telemetry in the management of exploited and endangered fish species. The papers present novel empirical data on the ecology of commercially important fish species, details about how such data were directly applied to management and policy issues, and address a range of key ecological and policy-relevant issues, including climate change, emerging fisheries, marine protected areas, Arctic ecosystems, invasive species control, and multi-species management and conservation. A lead article provides an extensive review of acoustic telemetry in management and conservation, noting the challenges, limitations, and ways forward.

Protected Areas as Socioecological Systems

Guest Editors: Graeme Cumming, University of Cape Town; Craig Allen, U.S. Geological Survey, Nebraska Cooperative Fish & Wildlife Research Unit, University of Nebraska – Lincoln

Three interesting and useful themes are emerging within social-ecological systems approaches to understanding protected areas. They include (1) increasing attention to the resilience and sustainability of protected areas, including analyses of their internal dynamics as well as of their effectiveness; (2) increasing consideration of the relevance of spatial context and scale for protected areas, including such factors as connectivity, context, and exchanges between protected areas and their surrounding landscapes; and (3) efforts to re-frame what protected areas are and how they both define, and are defined by, the relationships of people and nature. The papers in this Invited Feature link these three themes, while suggesting that management can be informed and potentially improved by explicitly considering social, ecological and economic aspects of protected areas, in a synthetic SES framework.

Centennial Special: Notable Papers in ESA History

ESA’s Centennial celebration included a reflection upon the most notable papers published in ESA journals. These papers made significant impacts on the science of ecology and are a starting point for contemplation, discussion, and future directions.The papers are freely available through the end of 2016.
