Session Description: Ecosystems are shaped by a physical template that includes climate, geomorphology, and surrounding land use.  However, understanding how changes in the physical template influence ecosystem processes is difficult due to the heterogeneity of landscapes and the many direct, indirect, and spurious linkages between landscape pattern and process, especially at broad-scales. This session looks at some of the new techniques and approaches being used to link landscape physical controls and ecosystem processes.  Ecosystem (fluvial or terrestrial) processes of interest include, but are not limited to, primary productivity, nutrient cycling, water cycling, and community dynamics. Interdisciplinary approaches are emphasized.

**Panel Session:1241 Advocacy in Biogeographic Science is scheduled on Wednesday, 4/14/10, from 10:00 AM - 11:40 AM in Tyler, Marriott Mezzanine Level

Organizer(s):Stockton Maxwell - West Virginia University

Panelist(s):Kenneth R. Young - University of Texas at AustinLaura C. Schneider - Rutgers UniversityLori D. Daniels - University of British ColumbiaGlen M. MacDonald - UCLAJohn Kupfer - University of South Carolina

Session Description: This panel session will bring together five respected biogeographers to discuss the issue of advocacy in biogeographic science.  Discussion will focus on key questions such as: 1) What is the role of the researcher in advocating for biogeographic research?  2) Should biogeographers speak with elected representatives to inform and advocate for positions supported by research?  3) Are there other avenues of advocacy?  4) Should researchers and students publish/present in layperson magazines/forums as well as scientific journals/conferences?  5) Should the biogeography community train new scientist to be savvy in the presentation and dissemination of their findings? 6) Should research questions be focused on application in the real world or with a specific "cause" in mind?  These are just a few of the questions that developing biogeographers must consider as their careers begin.  The answers are not concrete but we can learn from the experiences established scientists.

9:20 AM   Discussant: Michael W. Binford - University of Florida  Session Description: The seasonally dry tropical forests of southern Yucatán contain two of the most important Biosphere Reserves in Mexico: Calakmul (CBR) and Sian Ka'an. The conservation corridor between CBR and Sian Ka'an, the largest in extent for Mesoamerica, has been affected by several disturbances such as hurricanes, fires, droughts and last but not least land use change. Such disturbances have an important effect on forest functioning, specifically accelerating shifts in species condition, composition and distribution. In this session will examine and analyzed data on land cover change, MODIS Enhanced Vegetation Index, forest ecology, and land management practices to discuss the effects of environmental disturbances specifically hurricanes on the current socio-ecological conditions of the region.

The four papers will address the feedbacks between landscape dynamics, fire regimes and forest structure in response to hurricane Dean (Category 5 storm) which landed in the region August 21st of 2007.  The papers will: 1) present ways to assess hurricane damage at a regional level using remotely sensed data (MODIS) and locally using through plot level analysis; 2) discuss ways to link regional assessments to local plots and land use/cover change dynamics and 3) evaluate the socio-economic responses of the hurricane to forestry and agricultural activities using the results of 350 socio-economic surveys looking at vulnerability and adaptability of communities to droughts and hurricanes. Through these set of papers we would like to evaluate how compounded disturbances (e.g. land-use and hurricanes) interact in ways that can not be predicted by the study of a single disturbance.

Session Description: Lakes and ponds can be "natural laboratories for understanding how the ecological world functions" (Brönmark and Hansson, 2005:v).  Lakes and ponds are also linked in the geologic short term with their immediate terrestrial environments. This connection can make these water bodies both a storehouse of information and an alert system for the larger environment.In the Appalachian region, natural environmental systems intersect with the demands of nearby urban regions. Myriad lakes and ponds reflect the state of the environment in critical areas for urban watersheds, mineral resources, agriculture and forestry, and recreation.  A focus on small lakes and ponds allows an assessment at the finest landscape scale.

Session Description: Profound alterations in temperature and precipitation regimes, atmospheric composition and deposition, and land-use and land-cover patterns are contributing to unprecedented rates of environmental change on tropical mountains.  Observations of treeline and timberline movement, vegetation transitions, species range shifts, accelerated disturbance cycles, and glacier recession are increasingly well documented.  While these studies reveal broad-scale biological and physical responses to change, how such processes may in turn affect hydrologic and biogeochemical cycles remains less clear.  In this session, we will present recent research findings on the impacts of environmental change on water resources in tropical mountain regions and discuss the methodological constraints involved in extrapolating these findings to spatially heterogeneous landscapes.  The session will include research and insight papers that: (1) quantify direct effects of land-use and climatic variability on water and nutrient availability; (2) examine potential indirect effects of altered water resources on biodiversity, ecosystem function, and human populations; and (3) explore the influence of hydrological connectivity on ecosystem dynamics and biodiversity.

Canyon Reservoir, Utah 1920-2004

Session Description: Rapid environmental change is occurring in mountainous regions as a result of climate warming, atmospheric pollution, changes in stratospheric ozone, water diversions and other factors. In Western North America, mountainous regions can be thought of as "water towers" for the adjacent lowlands, providing water for household consumption, agricultural, hydro-electric power and even oil and gas extraction. These regions are also important ecosystems, recreational areas, and sources of many non-renewable resources. In order to effectively manage and protect these often remote areas, it is critical to have an understanding of the baseline conditions, natural variability and direction of change. Paleoenvironmental research provides a historical framework from which to determine these variables, and to assess the impacts of natural environmental change versus human activities.

6:00 PM   Author(s): *Abbie Tingstad - University of California - Los Angeles Abstract Title: A ~ 13,000-year record of environmental change from the Uinta Mountains, Utah inferred from diatom and loss-on-ignition analysis

Session Description: Rapid environmental change is occurring in mountainous regions as a result of climate warming, atmospheric pollution, changes in stratospheric ozone, water diversions and other factors. In Western North America, mountainous regions can be thought of as "water towers" for the adjacent lowlands, providing water for household consumption, agricultural, hydro-electric power and even oil and gas extraction. These regions are also important ecosystems, recreational areas, and sources of many non-renewable resources. In order to effectively manage and protect these often remote areas, it is critical to have an understanding of the baseline conditions, natural variability and direction of change.

Paleoenvironmental research provides a historical framework from which to determine these variables, and to assess the impacts of natural environmental change versus human activities.

Session Description: Restoration requires a broad perspective and range of expertise, and geographers provide the interdisciplinary background inherent to geographic training that strongly qualifies us to make significant contributions to the practice and science of environmental restoration.  Most of the sub-disciplines and many of the research specialties within them have important roles to play in one or more aspects of restoration.  In addition, environmental restoration is an excellent way to introduce undergraduates and graduate students to field research, test hypotheses about the functioning of natural systems, apply research findings to real-world problems, and train students for careers in a variety of fields.      This session brings together physical geographers conducting research directly related to environmental restoration for this session to highlight the contributions being made in this quickly expanding field. Whether the research is directed towards restoration planning and design; pre- and post-restoration monitoring; or another aspect of the effects of restoration on the biotic, abiotic, or biogeomorphic interactions in ecosystems, the session is open to a variety of geographic contexts and local to ecosystem-wide restoration projects.

Edwards - Smithsonian Institution, Museum of Natural HistoryJesús A. Ugalde-Gómez - Instituto Nacional De Biodiversidad (INBio)

Session Description: The loss of more than 100,000 species of plants and animals in the last five years alone is a major challenge for conservation of biodiversity.  Enhancing our knowledge of what is happening to which species--and where--is critical for organizations to effectively identify highest-priority concerns and mount multi-sector regional efforts to address them at ecosystem levels.   The collection and use of data to support biodiversity research, education, and conservation increasingly requires collection and organization of data into spatially-extensive and information-intensive technology systems that feature integrated cross-boundary capacities.  This phenomenon highlights the importance of geographic information systems and bioinformatics towards ecosystem conservation.  Building such knowledge systems across international and institutional borders bears potential as a framework for creating lasting collaborative communities and stronger capacity among participants in multiple sectors, ideally leading to changes in policy and practice.  Given this context, the panel will share insights about the relationships among science, practice, and policy with respect to ecosystem conservation, and will

discuss current priorities for worldwide ecosystem conservation that are implied by this state of affairs. The event forms part of the activities of the JRS Biodiversity Foundation funded project, "Enhancing Knowledge for Establishing Ecosystem Conservation Priorities in the Neotropics by Integrating Biodiversity and Geospatial Data," awarded to the Inter-American Biodiversity Information Network (IABIN) of the Organization of American States with partners: City of Knowledge (Panama), National Biodiversity Institute (InBIO-Costa Rica), Neotropical Bat Risk Assessments (Belize), Virginia Polytechnic Institute and State University, and the Association of American Geographers (AAG).

Session Description: Both anthropogenic and natural disturbances create and respond to spatial patterns across landscapes.  Contemporary landscape mosaics reflect these past disturbances, resulting in heterogeneous patterns of ecosystem function. Some disturbances, such as fire and forest insect outbreaks, are expected to increase in severity, extent, and frequency under climate change.  Other disturbances, such as land use change will continue to have persistent affects on ecological processes.  Importantly, future landscape patterns will reflect the interaction of multiple disturbance regimes making them difficult to forecast.  In this session, we bring together geographers with a range of perspectives on disturbances and disturbance interactions.  These perspectives span temporal (paleo-ecological to future) and spatial (individual plots to synoptic climatic patterns) scales, and bridge multiple methodologies (remote sensing, field ecology, and modeling).  Our aim is to highlight geographical perspectives on disturbance and disturbance interactions and to identify synergistic areas of future research.

Session Description: While many studies have linked climate as the primary driver of landscape evolution, increasingly, research has shown that other influences play important roles. Indeed, biotic processes can be critical determinants of landscape evolution, often rivaling or even eclipsing climate at the local scale. In this session we consider biotic processes that influence landscape evolution (e.g. biogeomorphology). Biogeomorphological processes include plant-soil interactions, herbivory, bioturbation, dune stabilization, and even anthropogenic disturbance, among others. Any change in these processes may manifest as changes in landscape. For example, the removal of herbivores can lead to a buildup of vegetation, and subsequent increase in fire, which can have important consequences for soil development, plant succession, and nutrient cycling. Earthworms have been referred to as "ecosystem engineers," indicating a disproportionate impact on the landscape. How do these biotic processes affect landscape evolution, and to what degree? How do we disentangle biogeomorphic processes from climate? What are the long-term ecological and geomorphic implications, if any? Biogeomorphology is at the crux of geomorphology and biogeography, incorporating research from above- and below-ground processes on terrestrial, aquatic and fluvial systems. The goal of this session is to broadly identify biogeomorphic processes operating at a range of spatial and temporal scales, and to highlight recent advances in this interdisciplinary field of physical geography.

 Session Description: This session focuses on (digital) photography and its application in assessing cross-temporal and/ or cross-spatial change from the microscopic to landscape scale. Examples could include more qualitative before-and-after pictorial comparisons employing photographs, ranging to quantitative photogrammetric (GIS) approaches. Archival studies that employ photographs (and rephotography) to track environmental history or change are also relevant. The central aim of the session is to examine how photographs have been deployed in the study of geomorphological and environmental change as well as for pedagogical purposes in the classroom or in the field. An objective is to capture the breadth of use and include creative, novel approaches in scientific research and learning.

Session Description: Biodiversity conservation relies on understanding the composition, structure, and dynamics of species, communities, and landscapes at target locations and ensuring positive human-r esource relations for biodiversity conservation. This illustrated paper session provides an opportunity to share the breadth of research that examines biophysical conditions and their influence on biodiversity patterns, human use of diverse resource for their livelihoods, and the impact of local and extra local forces on resource conservation. Accordingly, these studies should also demonstrate the mix of methodologies that are employed, and identify how different kinds of data from plot measures to expert narratives can be used to document ecological patterns of diversity and gain a culturally-sensitive sense of place from local residents in relation to these resources. Together, the presentations provide an opportunity to consider how ecological and cultural perspectives can be linked and effectively integrated in applied research for biodiversity conservation.

9:20 AM   Discussant: Celia Harvey - Conservation International

 Session Description: Recent discourse on protected areas (PAs) has centered on issues related to their effectiveness in conserving biodiversity and safeguarding essential ecosystem services, as well as their impacts on human welfare.  This discourse is nestled within the debate over the conflict of two societal "goods": conservation and poverty alleviation.  Several have suggested that this debate is rich in rhetoric, and poor in empirical evidence - even a "dialogue of the deaf" (Agrawal and Redford, 2006).  In this paper session, we step aside from the broader debate and focus on innovative ways to analyze and model the interaction between PAs and people.  Research presented in this session ranges geographically across the tropics from Latin America to India.  We emphasize the role played by both spatial and temporal scales on people and parks, and demonstrate unique ways to conceptualize and model the interactions between people and parks that extend beyond PA boundaries.  Each presentation will identify key lessons from the research for conservation policy.  The discussant(s), both working at the intersection of science, knowledge, and conservation policy, will speak to the implications of research design and scale to current priorities for conservation in the tropics.

Session Description: Our understanding of climate system dynamics at interannual to millennial timescales continues to advance as enhanced proxy networks and new techniques expand and refine the process of data collection, assimilation, and analysis. Robust paleoclimatic reconstructions are necessary for the objective analysis of past climate dynamics as well as assessment of observed trends and behavior over the last century. This in turn requires an improved, quantitative, and mechanistic understanding of the nature of the physical, chemical, and biological processes controlling proxy formation. At the same time, new proxies - including expanded archives and novel methods for using existing ones - are likely necessary to overcome the disadvantages of existing proxies related to geographic distribution, sensitivity, and bias. Integrating multiple proxies has also been shown to improve the skill of climate reconstructions and overcome weaknesses in single-archive approaches.
