The Maps and Local (MALS) project is a collaborative effort to develop common methods for research on social-ecological systems at the LTER network scale. (http://www.lter.uaf.edu/bnz_MALS.cfm)
Eleven sites have been funded to participate in MALS under the social science supplement for 2009-2010 and 2010-2011; another four sites are participating using other resources.
A four-day workshop will use LTER data, including data from the EcoTrends project, to bridge the gap between the relatively mature theoretical understanding of thresholds and state changes in ecological systems and the emerging empirical databases that allow us to actually test models of state changes.
Many of these changes represent “tipping points” or dramatic changes in the states of the systems, and our workshop will use data from terrestrial, coastal, and open-ocean systems to illustrate common mechanisms underlying state changes and threshold dynamics.
We are requesting Synthesis Working Group funds to support LTER participation in StreamchemDB.
StreamchemDB is focused on aquatic chemistry data, and builds on former data synthesis projects ClimDB and HydroDB, all of which have been collaborative LTER-Forest Service cross-site synthesis and cyber-infrastructure projects.
The goal of this workshop is to test hypotheses (identified in a 2010 working group) about ecological and social resilience of the water cycle to climate change and land use change in ten major river basins in the US and Canada.
The goal of this synthesis is to evaluate uncertainty in hydrologic inputs, outputs, and net hydrologic flux of major elements across small watersheds with diverse characteristics.
The long-term goal of this project is to contribute to a cultural change in ecology that makes uncertainty analysis an accepted and expected practice in the construction of ecosystem budgets.
We are requesting funds to assemble a working group of LTER scientists with extensive experience in conducting long-term experiments in the LTER Network, the skills and interest in synthetically interpreting the results of those experiments, and in using data from these studies to address new questions relevant to pressing global change issues.
Recent work has suggested that freshwater ecosystems may play a significant role in the global carbon cycle, potentially emitting 1.2 Pg C y-1 to the atmosphere [1, 2]. The majority of the CO2 that is degassed from streams and rivers comes from the decomposition of allochthonous leaf litter inputs [3, 4]. The process of decomposition fuels aquatic food webs, helps to regulate surface water acidity, and links biogeochemical cycles [5, 6].
MIRADA-LTERS is an NSF-funded cross-site comparative microbial inventory project that seeks to document, describe and discover baseline and novel diversity in the bacterial, archaeal and eukaryal domains of life across 13 of the aquatic LTER sites.
We request funds to bring 10 data managers/collaborators together to attend a 2 day workshop in Woods Hole sometime during the second week (8th-12th) of March. Five local MBL PIs and data manager Hap Garritt will join the 10 invited guests for an anticipated total of 15 people.
I would like to propose a 2-day meeting in 2010 bringing together scientists from any and all LTER sites interested in comparative soil organic matter analysis.
One day would be devoted entirely to planning cross-site comparative analyses and potential publications, and the other day would be devoted to discussions of the various tools and techniques that could and should be used for the questions posed.
A follow up workshop for a synthesis and modeling paper that builds on a workshop held at the LTER ASM 2009 meeting in Estes Park, CO (“Quantifying carbon and nutrient transformations in aquatic ecosystems at regional to continental scales
in response to environmental change”).
