|Detecting spatial regimes
Jan 09, 2017
|New research published in Ecology Letters by Shauna Sundstrom and colleagues uses data on terrestrial and aquatic animals to successfully detect spatial regimes and their transitions to alternate regimes.|
As ecological boundaries shift in response to climate change and other anthropogenic forces, detecting regime shifts using spatial data on animal communities, in place of vegetation communities used to define ecoregions, may provide more accuracy.
Using Fisher information, an information theory approach suitable for capturing patterns in system dynamics from multi-variate data, Sundstrom and colleagues used data from avian and zooplankton communities to identify spatial regimes and compare how well they line up with existing ecological boundaries determined using classification methods. The boundaries detected using animal data were considered to reflect ecological reality more than boundaries defined by the classification systems, suggesting that the approach could help with tracking shifting boundaries over time.
The authors also found the Fisher information approach consistently identified spatial regime shifts. They suggest that further research could help managers to select subgroups of species to monitor ecological stability within a community. Craig Allen, one of the paper's co-authors states "we believe the idea of spatial regimes is much more useful, potentially, in identifying impacts and responses to climate change than individually modelling species' responses".

|Carl Folke on the evolution of resilience research and thinking over 40 years, republished in Ecology & Society.|
Just in time for holiday reading - here is your chance to get up to date on 40 years of resilience research. Carl Folke, Science Director of the Stockholm Resilience Centre, and a leading scholar of resilience and social-ecological systems, has written a comprehensive summary of resilience for the Oxford Research Encyclopedia of Environmental Science that has now been re-published in Ecology and Society.
The paper follows a natural arc beginning with the foundational work on ecological resilience from Buzz Holling, next making the connection to integrated social-ecological systems as complex adaptive systems, followed by the less chartered area of the Anthropocene, making a strong case for building resilience to the unknown and unexpected.
Folke concludes by emphasizing how resilience thinking is embedded in the capacity of the biosphere to sustain development and human well-being.

|The Arctic is changing faster than ever - Arctic Resilience Report launched Nov. 25
Dec 01, 2016
|The first comprehensive synthesis and assessment of resilience in the Arctic, written by a team of international researchers.|
Change in the Arctic is rapid and accelerating. Understanding how to build resilience to help buffer, cope with and adapt to change has been boosted by the recently launched Arctic Resilience Report.
Written by an international team of researchers under the auspices of the Arctic Council, led by the Stockholm Environment Institute and the Stockholm Resilience Centre, the report's international team of authors identified 19 tipping points in Arctic marine, freshwater, and terrestrial ecosystems, including for example, the loss of Arctic sea ice, ocean hypoxia, collapse of fisheries, and transforming landscapes. Not surprisingly the biggest driver of change impacting Arctic communities and social-ecological systems is climate change.
Detailed case studies from across the circumpolar Arctic describe how 25 communities across the Arctic are responding to these unprecedented changes. The analysis reveals factors that help communities to be more resilient including: a capacity for self-organization, having a diversity of responses to change, learning and integrating different types of knowledge and being able to navigate and make decisions amidst uncertainty and surprise.
Achieving resilience in the Arctic will depend on individuals, communities, governments and institutions working across local to global scales to empower, support, and create integrated strategies.

|Post Resilience 2014

|A perspective paper in E&S and Post Resilience 2014 website that collects conference outputs in one place continues the discussion on resilience and development.|
Close to 1000 delegates attended the 2014 Resilience conference in Montpellier France and more than 600 presentations were delivered. Making the most of this opportunity, conference organizers conducted a comprehensive analysis of the archived material post-conference and synthesized their findings in a perspective paper recently published in Ecology & Society.
"Resilience and development: mobilizing for transformation" seeks to extend the dialogue on the intersecting perspectives of resilience and development. As the authors state in its introduction "The objective of this analysis is not to propose an integrated framework but rather to highlight the main research questions put forward during the conference and how they are approached and formulated from the different perspectives." Readers are encouraged to submit a response to the paper, using the journal's response feature and also to continue the conversation on resilience and development at the upcoming resilience conference in Stockholm 2017.
A new website http://www.postresilience2014.com designed to collect and share outputs from Resilience 2014 also offers an opportunity to comment directly on the perspective paper in E&S as well as to collect and share outputs and outcomes from the conference sessions (links to papers, blog posts, videos, projects, etc.).

|Bright spots: seeds of a good Anthropocene
Oct 13, 2016
|A new paper by Elena Bennett and colleagues challenges dystopian future scenarios with "bright spots"|
Bright spots: seeds of a good Anthropocene, published earlier this month in Frontiers of Ecology and the Environment, explores how examples of positive change in future scenarios, borrowed from existing real-world initiatives, can help us to understand both what people want from a better future and the processes needed to get there.
The paper draws on examples of positive change from around the world that have been collected in an online "seed" database that began as part of the Future Earth project Good Anthropocenes http://goodanthropocenes.net.
The seeds represent a wide range of practices around the world that could help accelerate pathways of transformative change. Each seed offers an example of the types of bottom-up change needed to move towards more sustainable futures.
Elena Bennet spoke of the seeds project in a 5-minute talk she gave this past summer at the World Economic Forum meeting in Tianjin:

|Body size distributions signal a regime shift in a lake ecosystem
Sep 14, 2016
|A recent paper by Spanbauer & colleagues demonstrates how discontinuities over time in the body size of diatoms signaled a regime shift in a mountain lake 150 years before it happened.|
One of the greatest challenges surrounding regime shifts is identifying them before they happen. In recent years there has been a variety of methods proposed for detecting early warning signals for regime shifts. Within this specialized field Craig Allen and colleagues have focused on patterns of discontinuity. In a recent paper Spanbauer et al, co-authored by Craig and several other RA members, they demonstrate how discontinuities over time in the body size of diatoms signaled a regime shift 150 years before it happened.
A regime shift implies crossing a threshold and changing how the system is structured and how it functions as well as how it maintains the new regime through system feedbacks. A well studied, climate-driven regime shift in Foy Lake in the northern Rocky Mountains made it possible for the authors to examine fossil diatoms spanning thousands of years to compare the size aggregations of diatoms with known stable periods in the history of the lake.
The authors found that size aggregations changed with the regime shift, suggesting that discontinuity analysis may provide a complementary method of detecting regime shifts that would potentially allow sufficient time to intervene and manage for resilience.

|Recently published research from RA member Dirac Twidwell and colleagues explores the potential use of unmanned aerial systems (UAS) for fire management, including a prototype fire drone.|
Managing wildfire and fire-adapted ecosystems often involves lighting fires, either as part of suppression tactics to reduce fuel load or as part of a prescribed burning plan. The task can be made safer according to Dirac Twidwell, Craig Allen and colleagues by using drones (UAS) to ignite fires.
In a paper published this month in Frontiers in Ecology & the Environment, the authors explore how fire management, particularly in the U.S., has changed over time with escalating costs as well as risks to individuals, and they propose a solution. The team of researchers have developed and tested a fire-igniting drone with the potential to both reduce risks to fire crew and costs compared to helicopter-based ignitions.
Craig Allen, who co-authored the paper says the UAS could be used specifically to help fight an ongoing regime change in the great plains - the change from grassland to woodland driven by cedar invasion and mediated by the loss of fire. The use of UAS in fire management is not limited to ignition and could include fire monitoring, data collection, and improved transmission of information and communication. The authors describe some of the institutional challenges associated with implementing this type of technological innovation and the potential to improving the effectiveness of fire management in both the U.S. and internationally.
