Leslie Lab members published results from a multi year study at 18 rocky shore sites from Maine to New York state in Ecosphere this week.
Mussels could be the perfect ‘sentinel’ species to signal the health of coastal ecosystems. But a new study of blue mussels in estuary ecosystems along 600 kilometers of coastline in the Northeast uncovered three key mysteries that will have to be solved first.

In this age of ever increasing technological capacity and the global reach of economies, political institutions, and yes, disease and other environmental harms, we scientists do not have all the answers to the question every citizen asks: What shall we do? We do, however, know a lot that can help.
In the comment published today in Nature by Heather Tallis and 239 other scientists (including myself), we scientists have come together to urge that our field of conservation science moves beyond the question and focus on finding solutions – many solutions, not one solution – to sustain both people and nature on our planet.
As a founding faculty Fellow of the Institute for the Study of Environment and Society at Brown University, I’m participating in an exciting effort to do exactly this. Institute faculty are creating new knowledge of how social-ecological systems work and translating that science in ways that speak to decision makers at every level, from the local to global. Brown students mentored by sociologist Timmons Roberts are crafting a strategy to help implement the Resilient Rhode Island Act that some of them helped draft last spring. Students mentored by ecologist Kate Smith are investigating human and wildlife diseases in Rhode Island and around the world, and their implications for conservation and human health. Microbial ecologist Jeremy Rich is diving to the depths of the tropical Pacific later this week to study the microbes that the form the base of the food web in a marine ecosystem humans first visited less than 40 years ago: hydrothermal vents. And in my own research group, we are exploring how diversity in the ecosystems and social organizations related to marine fisheries can contribute to the resilience of coupled systems to climate variability and change.
I believe that the research that my colleagues and I are engaged in all fall under the rubric of conservation science – science to inform actions to sustain life on earth – and yet not all of us consider ourselves conservation scientists, and certainly we are not all motivated by the same values or scientific objectives. This diversity of scientific perspectives and worldviews is critical for conservation to succeed, as we note in the Nature piece.
We need to ensure that the dialogue and the doing of conservation science welcomes the full diversity of genders, ethnicities, worldviews, and cultures in whose name we are generating this science. My hope is that the Nature piece encourages all us to think harder about how to do this well, and to get down to work.
I look forward to sharing my own efforts in future posts and encourage you to do the same, at http://diverseconservation.org/ or via twitter at #diverseconservation.

Citation: Sievanen, L. 2014. How do small-scale fishers adapt to environmental variability? Lessons from Baja California Sur, Mexico. Maritime Studies 13:9.
The abstract follows:
Many fisheries stocks and the livelihoods of those who make their living from fishing are in decline, and these declines are exacerbated by uncertainties associated with increased climate variability and change. Social scientists have long documented the importance of mobility and diversification in reducing the risk and uncertainty associated with climate variability, particularly in the context of small-scale fishing. However, it is unclear how these traditional mechanisms are buffering fishers againstthe varied stressors they currently face, including those associated with environmental variability. This paper examines how fishers on the southern gulf coast of the Mexican state of Baja California Sur perceive and respond to stressors associated with normal environmental variability, how their ability to adapt is spatially distributed, and what threats they perceive to their continued ability to adapt. Understanding the adaptation strategies and everyday vulnerabilities that fishers face can elucidate problems associated with current fisheries management and the underlying factors that cause vulnerability, and also help decision makers, including fishers themselves, develop more effective adaptation strategies in the face of climate change.

Heather Leslie, assistant professor of environmental studies and biology, says it’s a mistake to assume market forces and sustainability must always be at loggerheads. In a recently published paper in Ecological Applications, Leslie and a group of researchers showed that small-scale fisheries near La Paz, Mexico, could earn a premium for fish that fit nicely on a plate, leaving larger fish to sustain the population.

Heather and colleagues from a diversity of academic, private, and non governmental institutions just published an article in Conservation Biology on the power of linking good stories and good science. Featuring the story of Cabo Pulmo, a marine conservation success story from Mexico’s Gulf of California, the authors reflect on the diverse roles that stories can play in advancing conservation science and practice:
“As scientists, we are part of these stories and often in the best position to tell them (Baron 2010a). Stories represent an opportunity for scientists to connect their work to the wider world, if they have the patience and creativity to write narratives that include tension (Franklin 1994; Olson 2009) and put people front and center (Kristof 2009)…
We believe there are benefits to connecting conservation science and stories, in terms of evaluating and achieving conservation effects and disseminating those outcomes to other practitioners and the public. But conservation scientists will only know this is true if they engage in these activities more frequently and with greater intent and then systematically analyze the effects. To our knowledge, this has not yet occurred.
Unsubstantiated conservation stories are a danger and could damage the credibility of conservation science or distract policy makers from the magnitude of conservation challenges, but we believe conservation science and practice would be enriched by more efforts to thoughtfully connect science and stories.”

Former Brown undergraduate Joey Bernhardt and Prof. Heather Leslie just published a synthetic review on ecological resilience to climate change in the Annual Review of Marine Science. The abstract follows; navigate to the site to see the full review, or contact Heather for a PDF.
Abstract. Ecological resilience to climate change is a combination of resistance to increasingly frequent and severe disturbances, capacity for recovery and self-organization, and ability to adapt to new conditions. Here, we focus on three broad categories of ecological properties that underlie resilience: diversity, connectivity, and adaptive capacity. Diversity increases the variety of responses to disturbance and the likelihood that species can compensate for one another. Connectivity among species, populations, and ecosystems enhances capacity for recovery by providing sources of propagules, nutrients, and biological legacies. Adaptive capacity includes a combination of phenotypic plasticity, species range shifts, and microevolution. We discuss empirical evidence for how these ecological and evolutionary mechanisms contribute to the resilience of coastal marine ecosystems following climate change–related disturbances, and how resource managers can apply this information to sustain these systems and the ecosystem services they provide.

Ocean Health Index provides first global assessment combining natural and human dimensions of sustainability
Sustainable management of a huge, complex and valuable resource such as the ocean requires a comprehensive metric that did not exist until now. In the Aug. 16 edition of Nature a broad group of scientists including Heather Leslie, the Sharpe Assistant Professor of Environmental Studies and Biology, describes the Ocean Health Index. The index rates coastal places, from regions to nations, on 10 goals: artisanal fishing opportunity, biodiversity, carbon storage, clean waters, coastal livelihoods and economies, coastal protection, food provision, natural products, sense of place, and tourism and recreation.
To learn more about how the index can be applied to assess the effectiveness of ocean management and guide future stewardship efforts, read a recent Q&A with Heather and related articles from the NY Times and Nature News, or contact the authors.
