Cross-site Science
Japanese LTER Network (JaLTER) - Collaborated Activities for Integrated Ecosystem Observation and Research
Japan Long Term Ecological Research (JaLTER) Network was established in 2006, currently consisting of 18 core sites and 38 associated sites that represent forest, grassland, lake, and marine ecosystems.
JaLTER is an official member of International LTER (ILTER) Network since 2007.
A New Network for Hurricane Researchers
The U.S. and Mexican LTER Networks are cooperating in the development of a new network of hurricane researchers.
LTER Europe – developing a new approach to ecosystem research, its communication and implementation
The outcomes of the Millennium Ecosystem Assessment (2004), Global Environmental Outlook (2007) and reports of EEA (2007, 2005) on the state of European environment clearly showed that the future of nature management depends on changing the way individuals think about the environment and its impact on human well-being, decision makers consider and treat environmental values, scientists communicate their findings, and financial resources are mobilized and allocated to solve environmental problems.
Seabirds as Indicators of Climate Change
A new Schoolyard children's book called Sea Secrets: Tiny Clues to a Big Mystery uncovers clues connecting the Cassin's Auklet from the California Current Ecosystem LTER and the Adelie penguin from Palmer Station LTER helping students understand that seabirds may be indicators of climate change.
SPAN: A Sensor Processing and Acquisition Network
In recent years, advances in sensor network technology have shown great potential to revolutionize environmental data collection. Still, these systems have remained the purview of the engineers and computer scientists who design them, rather than useful tools for the field scientists who need them. Today, there are many data logging options for basic data collection in the field, but scientists are still required to travel to their sites to collect data, and to manually import data into spreadsheets.
VOSS: Delegating Organizational Work to Virtual Organization Technologies
This project is currently undertaking a comparative study of the formation and maintenance of Virtual Organizations (VOs) in two leading collaborative science networks: the Long Term Ecological Research Network (LTER) and the Open Science Grid (OSG). Both LTER and OSG are mature enterprises for supporting multidisciplinary scientific research; however, they differ in the nature of their VO tool use.
A Collaborative Database of LTER Projects at Sites
Experiments or projects are central to all research endeavors, and LTER sites encompass many. Research projects are commonly documented at the site-level using various methods in order to maintain records for annual reporting, field site permissions, coordination of research activities in space and time, and for linking datasets and other products to individuals.
Is there evidence for a trade-off between cold tolerance and growth among North American willows?
It has been hypothesized that the range limits of woody plants are determined by a trade-off between freezing tolerance and growth rate, such that species with high freezing tolerance have low growth rates. However, willows (genus Salix) appear to be an exception to this pattern as they have high growth rates and high freezing tolerance. To determine whether there is evidence for this trade-off in willows, I compared the growth and freezing tolerance of twenty-eight willow species collected across North America.

Defining Learning Progressions in the Science and Culture of Water
Population growth has and will continue to put pressure on our water resources. Yet students are only exposed to rudimentary basics that lend themselves to engaging in indoor experimentation (e.g. water phase changes and the water cycle) and fact-based assessments. Consequently, the majority of citizens hold on to inaccurate conceptions of where water exists, how it moves, how it gets used, and how it relates to biodiversity and climate change. These more critical concepts, unfortunately, do not appear in state content standards or assessments.
