    Researchers detail climate-change impacts in ecological journal 5 November 2013 also senior author of two of the papers. To produce this special issue of ESA's Frontiers, a diverse group of over 50 ecological scientists and other stakeholders condensed and illustrated the work they had done for a technical input report on biodiversity, ecosystems and ecosystem services for the U.S. National Climate Assessment. The assessment is due to be released in 2014. The collection is aimed at both ecologists and practitioners. The authors hope to demonstrate the potential for researchers to collaborate with practitioners in identifying "policy relevant questions" – information that practitioners need to Climate change is already increasing the frequency of make science-based decisions about management extreme events, such as storms, which directly affect of natural resources.

    RisingRising toto thethe ChallengeChallenge Annual Report 2009 From the Executive Director ESA remains financially sound and programmatically strong. n spite of the difficult economic times the country is I facing, ESA remains financially sound and programmatical- ly strong. Our loyal membership stands near 10,000 and the annual meeting—this year in Albuquerque—attracted 3,599 participants with its excellent program offerings. More than 2,000 institutions worldwide subscribe to one or more of our journals, which continue to be among the most highly cited in our field. Ecology, which is 90 years old this year, was named by the Special Libraries Association (SLA) as one of the top 100 most influential journals in science and medicine in the past 100 years. ESA is engaged in a range of activities that are a testament to the breadth of interests of our members. From congressional briefings on “hot” issues to an energized blog; from specialized ESA file photo Credit: conferences and workshops to galvanizing the community behind data sharing; from the continued evo- lution of our prized diversity program to helping faculty use large scale data sets; and from the ever- increasing influence of our journals, ESA continues to be a vibrant and energized society. ESA is also looking to the future. This year, the Governing Board initiated a long range planning process that will examine the existing activities of the Society and anticipate programs and activities that may be needed in the future. We expect that many of our members will be involved in this effort and be asked to help us ensure that ESA stays relevant far into the future.

Eden kOregon John Hines Montana Steve Crow Executive Director December 2, 2003 DECISION MEMORANDUM To: Council Members From: Erik Merrill and Steve Waste Subject: ISRP and ISAB Appointments Proposed Actions Council staff requests Council actions and discussion pertaining to Independent Scientific Review Panel (ISRP) and Independent Scientific Advisory Board (ISAB) member terms and appointments. Staff asks that the Council: 1) Appoint Dr. John Epifanio, Illinois Natural History Survey, as a member of the ISRP. 2) Approve extension of term limits for the current ISRP members through May 2005. 3) Initiate the process to rebuild the pool of potential ISRP and ISAB members for future appointments by reconvening the National Research Council nomination committee, and, with NOAA Fisheries and the Columbia River Indian Tribes, jointly sending a letter to the region requesting nominations for consideration by the NRC nomination committee. 4) Discuss ISAB member renewals and the appointment process for new ISAB members. The ISRP and ISAB have different responsibilities in the Council’s Fish and Wildlife Program, and the Council plays distinct roles in the administration of each group. To avoid confusion between the groups, this memo addresses decisions and background information related to each group separately, first the ISRP and then the ISAB.

    2015 Distinguished Scientist Seminar Semester in Environmental Science MBL ECOSYSTEMS CENTER, WOODS HOLE, MA Mercedes Pascual Professor, Dept. of Ecology and Evolution University of Chicago Infectious Disease Dynamics under a Changing Climate September 18th — 2:30 PM Lillie Auditorium, MBL Mercedes Pascual is a mathematical ecologist interested in predicting the behavior of dynamic biological systems. She has published on a wide range of topics including chaotic behavior in predator-prey populations, controls on phytoplankton growth, and the structure and dynamics of food web networks. In recent years, she has focused her research on the question of how a warmer climate, together with an increasingly mobile, urbanized and growing human population will affect the geographic distribution, transmission and incidence of diseases such as cholera, malaria and leishmaniasis, a parasitic disease that is found in parts of the tropics, subtropics and Europe. Dr. Pascual is currently a professor in the Department of Ecology and Evolution at the University of Chicago. Prior to coming to Chicago, she was a Rosemary Grant Collegiate Professor at the University of Michigan, holding appointments in both Ecology and Evolutionary Biology, and at the Center for Computational Biology and Bioinformatics. She earned a M.Sc., Mathematics from New Mexico State University and a doctorate in Biological Oceanography from the joint program of the Woods Hole Oceanographic Institution and the Massachusetts Institute of Technology. She has received a number of awards and honors. She was elected a fellow of the American Association for the Advancement of Science in 2003 and was named one of the top 50 Women in Science by Discover Magazine that same year.

    HydroEco 2017 Ecohydrology on the Edge: ecology-hydrology-human interactions in a changing world 6th International Multidisciplinary Conference on Hydrology and Ecology University of Birmingham 18-23 June 2017 1 About HydroEco2017 Ecohydrology as a scientific discipline has been emerging from the need to address the interactions and feedbacks between ecological, hydrological, geomorphological and atmospheric processes, and aims to understand and predict fast changing aquatic-terrestrial environments. Over the last decade, the scientific discipline of Ecohydrology has seen rapid technological and conceptual developments. The highly dynamic and often non-linear behaviour of ecohydrological processes pose unique challenges in understanding, monitoring and conserving freshwater ecosystems. Complex process interactions often cause ecohydrological processes to show pronounced temporal dynamics and exhibit marked non-linear behaviour in response to environmental change. Such behaviour manifests itself by the occurrence of distinct thresholds, tipping points or hot moments, periods of enhanced (re)activity and rapid regime shifts; but may also be associated with pronounced spatial heterogeneity, producing locations of enhanced activity or hot spots. The 6th International Multidisciplinary Conference on: Hydrology and Ecology will focus on “Ecohydrology on the edge: ecology-hydrology-human interactions in a changing world” 2 Contents Contents Local Organisers .......................................................................................................................................

Urbanization is increasing and climate change is an emerging threat. These two realities of the 21st century are on a collision course. The Urban Resilience to Extremes Sustainability Research Network is working with city practitioners to improve resilience and envision positive futures for US and Latin American cities. In Phoenix, this work benefits from 20 years of research in the CAP LTER program, which formed the basis for regional scenarios co-developed with governmental, non-governmental, civic leader, and academic partners. To set the stage, I will present an overview of the water-related research in Phoenix of my group and others, and then I will describe the co-produced future scenarios for the region and for South Mountain Village. I ask, how do the scenarios differ between these two scales, do they reflect true transformation or mere tweaks, and what tradeoffs are associated with different scenarios? Finally, I present a qualitative assessment that evaluates whether the scenarios improve resilience in the face of future extreme events.
