Background: The Sevilleta LTER possesses a large network of diverse research sites, weather stations, and webcams interconnected by a wireless network that can be remotely accessed by researchers around the world. Presently, there are approximately thirty networked research sites comprising of over fifty dataloggers, thousands of sensors, and several webcams distributed over more than 100… Read more »

Web Services Working Group (WSWG)- IM Buyout
A redesigned personnel database will be available for all sites and the LNO to use via a web service interface. This interface may be used for the two distinct approaches currently in use by the LTER sites: Used directly by local site applications, or Used as a target for sites doing both read and write… Read more »
Coordination and Reports related to EML Congruency Checker
Current experience using Ecological Metadata Language (EML) datasets contributed to the LTER NIS indicates that a significant fraction is not of sufficient quality for automated use. I propose to spend one month (160 hours) over the course of 2011 on three tasks which will help sites contribute “PASTA-ready” EML datasets, and which communicate LTER activities… Read more »
Defining Checks to Ensure High Quality LTER Data Packages
Summary: The “quality” of a data package is a reflection of how well it may be used for a specific purpose. The emerging LTER Network Information System (NIS) is being developed to ingest EML datasets and process them in automated workflows. To do so, a data package must include access to data, complete metadata (defined… Read more »
Retrieving and using information from web services to improve EML content
Many content sections of an EML documents may now be easily standardized, improving on discoverability and potentially easing the development of the documents. This is due to the fact that some pertinent information in authoritative databases is now available via webservices. This workshop will show LTER Information Manager how to access this information, transform it… Read more »
Drupal Environmental Information Management System (DEIMS) workshop: A workshop for new and advanced DEIMS users
The Drupal Environmental Information Management System (DEIMS) (San Gil et al, 2010) group is building an information management system based on the open source Drupal Content Management System. Drupal is used for managing information, from the database backbone to the dynamic website portal look and feel. DEIMS consists of a user-friendly metadata editor coupled with… Read more »
The influence of precipitation variability on diversity and composition of North American grasslands
Predictions regarding future climate change vary greatly among regions, and these predictions include directional changes such as more arid conditions in the US Southwest (Seager et al. 2007), as well as an expectation of greater interannual variability (Easterling et al. 2000). Ecologists are charged with identifying biotic communities and ecosystems most at risk for declines… Read more »
Veg-DB: Developing a cross-site system to improve access to vegetation synthetic databases
Working Group Goals: Given that this is the first attempt to address the issue of network availability of vegetation data our goals are extremely fundamental but critical at this stage: Assess the willingness of sites to participate in a Veg-DB system. Given the complexity of these databases, participating in this system will require a significant… Read more »
Bi-stability in North American ecosystems: analyzing woody plant cover for temporal stable-state dynamics
Woody encroachment is occurring worldwide (Archer 1995), with negative effects on biodiversity in North America (Ratajczak et al. in press) and uncertain effects on ecosystem functioning (Barger et al. 2011). The spatial properties of tree and grass dominance are well-studied and strongly suggest that woody encroachment of grasslands represents a shift to an alternative stable… Read more »
Land Use Institutions, Land Use Land Cover Change, and the Distribution of Ecosystem Services
Zoning, building codes, subdivision ordinances, and neighborhood association rules are the most pervasive institutions affecting land use in the USA, yet their impact on land use change and ecosystem services and the distribution of these environmental goods and “bads” is highly variable and not well understood[1]. The purpose of this working group is to coordinate… Read more »
