To effectively manage and protect species within an ecosystem, it is essential to know where they exist. There are currently two global marine species distribution datasets that contain ranges for nearly 25,000 species: IUCN and Aquamaps. Due to the different methodologies and resulting species distributions between these two databases, the Ocean Health Index Working Group compared species range maps within both datasets to identify differences and possible data limitations. Their findings were published in a recent PLOS ONE publication. More>

The complexity of marine ecosystems has long presented a challenge to fisheries management in coastal communities. Recognizing that many fish stocks are on the decline, managers and researchers alike have identified the importance of evaluating the mechanisms that link environmental, ecological, and human systems together. Identifying how these systems interact with each other will allow for a more precise understanding of their collective impact on fish populations. The Gulf of Alaska Dynamics working group set out to produce a comprehensive analysis that attempts to model the varied effects of these complex interactions on focal groundfish species of coastal Alaskan communities. Their publication in the ICES Journal of Marine Science catalogues the multitude of natural and anthropologic complexities that impact fisheries stock. More>

Tropical forests dominate global terrestrial carbon exchange, but long-term climate variability might affect their ability to uptake and store carbon dioxide. To better understand tropical forest carbon dynamics, the Tropical Nutrient Limitation Working Group assembled published datasets to determine how temperature and rainfall interact to control carbon cycling in tropical forests. Their results are featured in a recent Ecology Letters publication. More>

The increasing amount of international transport and exchange requires a better understanding of the mechanisms behind invasive species dispersal. As we send goods across trade routes around the world, we also provide new pathways of invasion for non-native species. The NCEAS working group assessing the effects of trade policy on the management of non-native pests recognizes the ecological and economic significance of understanding invasions, and has recently published a study in the Journal of Applied Ecology that aims to improve predictions of invasion rates.

With the constant demand for wood products, the “sharing vs. sparing” question remains whether we should promote the intensification of production in small areas with intent to spare large areas of forest from human impacts, or promote best practices for extensive low-intensity harvests from native forests. In a new Conservation Letters publication, the SNAPP Forest Sharing or Sparing Working Group investigated how to meet the demand for wood products while minimizing CO₂ emissions and biodiversity losses.

Now more than ever, effective science communication is essential for scientists to share their findings with each other as well as the general public. A new opportunity has emerged in the form of very short, swift presentations that help bridge the gap between lengthy, detailed scientific presentations and short sound bites. In a recent PLOS Computational Biology paper, NCEAS senior fellow Christopher Lortie presents ten simple rules for successful short and swift presentations. More>

Integrated land-sea management (ILSM) is a type of resource management that targets threats and processes across land and sea ecosystems in order to maintain biodiversity, ecosystem services, and human well-being. Since island peoples rely on natural sources for survival, a proactive, integrated management system across linked land and sea realms is essential for the continued provision of resources. In order to gain a better understanding of the opportunities and constraints for implementing ILSMs on islands, the SNAPP Ridges to Reef Working Group developed indicators for assessing management principles, and evaluated the performance of planning and implementation on four ILSMs on islands throughout the tropical Pacific. Their findings are found in a recent Environmental Conservation publication. More>

The National Science Foundation (NSF) added three new sites to the Long-Term Ecological Research (LTER) Network, bringing the total number of U.S. sites to 28. The new sites, which focus on areas with highly productive fisheries, will add a much stronger marine emphasis to the LTER Network. More>

The Long-Term Ecological Research (LTER) Symposium will be held at the National Science Foundation (NSF) Headquarters in Arlington, Virginia on March 21, 2017. Featuring five talks from researchers across the LTER Network, the symposium will highlight how science through long-term research can help determine which changes in ecological systems may allow for recovery and which are more likely to irreversibly transform ecological systems. Changes to ecological systems are attributed to pressures such as sea-level rise, drought and fire, which are further exacerbated through a changing and climate. Visit the symposium website for more information. More>

Despite long term data collection in the Gulf of Alaska since the Exxon Valdez Oil Spill in 1989, the degree to which the spill affected fish populations remains controversial. Productivity of herring and some species of salmon have declined compared to the late 1970s or 1980s, but it is unclear if this reduction is a result of the oil spill. In a recent PLOS ONE publication, the NCEAS Gulf of Alaska Portfolio Effects Working Group examined herring and salmon productivity over time to determine if lack of recovery for these species was due to the oil spill or other environmental factors such as freshwater discharge or competition.

Despite a history of habitat restoration focusing on single species recovery, a new study affirms this is not necessarily the most efficient approach. A team of scientists, including NCEAS Director Ben Halpern and NCEAS researcher Adrian Stier, show that synchronous predator and prey recovery can be twice as fast in restoring ecosystem functioning. Their new publication in Nature Ecology & Evolution conveys the importance of ecosystem-level approaches to management and the other social benefits that could arise from these management changes.More>

Runoff from upstream, land-based pollutants jeopardizes the ocean's coral reefs and adversely impacts the production of goods and services critical to many coastal residents. But how do you address a challenge that spans both land and sea? A recent study, published in the Journal of Environmental Management and part of the larger Ocean Tipping Points project, found that cooperation among landowners to reduce sediment runoff to nearshore reefs leads to more cost efficient and ecologically effective results compared to scenarios when landowners act independently.

Entrance fees levied on users of protected wild places are effective management tools as they help to reduce damages associated with over-use and cover inherent administrative, maintenance, and operational costs. A recent case study of Nyungwe National Park, Rwanda that was published in Science Direct and supported by SNAPP Natural Capital Accounting working group found that differences in park uses and preferences between international and national visitors allow for an equitable pricing system that effectively covers park costs.More>

Researchers recently applied the Ocean Health Index (OHI) tool for an individual assessment of Antarctica's Southern Ocean ecosystem health. Despite the region being considerably inaccessible and removed from human influence, the index report found that the ocean ecosystems are not necessarily pristine. NCEAS Director and OHI Lead Scientist Ben Halpern shares the results of the assessment as a contributor to a recent publication in Frontiers in Marine Science, which highlights the gap in Antarctica realizing its full ocean health potential.

The SNAPP Amazon Waters Working Group has discovered that the western Amazon is the main spawning area for the "goliath" catfish, and that the dorado catfish has the longest freshwater fish migration. The team published its study and results in the journal Scientific Reports-Nature. The authors warn that future development in and near these spawning grounds could negatively impact the fishes' migration and the fishing industries that rely on them. More>

Both population growth and climate change put a strain on natural resources and degrade their ability to provide ecosystem services. In places with growing populations and changing climates, people could be in trouble. In a recent PLoS One paper, researchers examined changes in wet season precipitation and population over the past 30 years. Trends identified areas where key ecosystems are threatened by the combined effects of climate change and population growth, and therefore where human populations are most vulnerable to degraded ecosystem services.
