Abstract

Sea turtles are an iconic group of marine megafauna that have been exposed to multiple anthropogenic threats across their different life stages, especially in the past decades. This has resulted in population declines, and consequently many sea turtle populations are now classified as threatened or endangered globally. Although some populations of sea turtles worldwide are showing early signs of recovery, many still face fundamental threats. This is problematic since sea turtles have important ecological roles. To encourage informed conservation planning and direct future research, we surveyed experts to identify the key contemporary threats (climate change, direct take, fisheries, pollution, disease, predation, and coastal and marine development) faced by sea turtles. Using the survey results and current literature, we also outline knowledge gaps in our understanding of the impact of these threats and how targeted future research, often involving emerging technologies, could close those gaps

4. Vision and Change in the Biology Community: Snapshots of Change

Author

Vasaly, Helen L., Feser, Jason, and Lettrich, Matthew D.

Abstract

When the authors were first invited to write these columns, the editors felt it would be an interesting way to give the readers of "CBE - Life Sciences Education" an agency's-eye view of its concerns, workings, and accomplishments. This column is written with that charge in mind. It is intended to inform the community about outreach efforts, some of the mechanisms used, and the effectiveness of these efforts. In 2007, the National Science Foundation (NSF), the American Association for the Advancement of Science (AAAS), the Howard Hughes Medical Institute (HHMI), and the National Institutes of Health (NIH) launched an initiative called Vision and Change in Undergraduate Biology Education (V&C), designed to enable the biology community to address the challenges of preparing undergraduates for 21st-century biology using 21st-century findings about effective teaching strategies. Over the next 2 years, with support from the partners listed above, the community engaged in "conversations" among faculty, administrators, students, and professional societies through a series of workshops. Those conversations culminated in a working conference in 2009, in which more than 500 faculty, administrators, and students pooled their collective wisdom. The tangible result from all this effort, "Vision and Change in Undergraduate Biology Education: A Call to Action," is a document setting forth their vision of the approaches needed to ensure undergraduate biology education truly reflects the biology of the 21st century in both the content included and the competencies developed and the delivery reflects what is known about effective teaching practices. Since the release of the report, many organizations, including those listed above, the U.S. Department of Agriculture, the National Research Council, and a number of professional societies have led efforts to disseminate the document and engage the biology community in efforts to implement the actions outlined in it. This article discusses how successful these efforts have been. Six years after those initial conversations, it is important to try to determine the extent of dissemination and implementation of V&C, not only to determine the challenges ahead and possible next steps, but also to begin to establish mechanisms for effective response when a science experiences the sort of rapid evolution in approach, resources, and focus that has occurred recently in biology.

Abstract

Climate-related shifts in marine mammal range and distribution have been observed in some populations; however, the nature and magnitude of future responses are uncertain in novel environments projected under climate change. This poses a challenge for agencies charged with management and conservation of these species. Specialized diets, restricted ranges, or reliance on specific substrates or sites (e.g., for pupping) make many marine mammal populations particularly vulnerable to climate change. High-latitude, predominantly ice-obligate, species have experienced some of the largest changes in habitat and distribution and these are expected to continue. Efforts to predict and project marine mammal distributions to date have emphasized data-driven statistical habitat models. These have proven successful for short time-scale (e.g., seasonal) management activities, but confidence that such relationships will hold for multi-decade projections and novel environments is limited. Recent advances in mechanistic modeling of marine mammals (i.e., models that rely on robust physiological and ecological principles expected to hold under climate change) may address this limitation. The success of such approaches rests on continued advances in marine mammal ecology, behavior, and physiology together with improved regional climate projections. The broad scope of this challenge suggests initial priorities be placed on vulnerable species or populations (those already experiencing declines or projected to undergo ecological shifts resulting from climate changes that are consistent across climate projections) and species or populations for which ample data already exist (with the hope that these may inform climate change sensitivities in less well observed species or populations elsewhere). The sustained monitoring networks, novel observations, and modeling advances required to more confidently project marine mammal distributions in a changing climate will ultimately benefit management
