The MIRADA LTERs project (see working group materials) is an NSF-funded Microbial Biodiversity Survey and Inventory across all 13 of the major aquatic (marine and freshwater) Long Term Ecological Research (LTER) sites. The long-term objective of our study is to document and describe baseline diversity and relative abundance data for both common and rare members of microbial communities located in aquatic LTER sites and to relate this diversity to the underlying physical and chemical...

Sequencing the expressed genetic information of an ecosystem (metatranscriptome) can provide information about the response of organisms to varying environ mental conditions. Until recently, metatranscriptomics has been limited to microarray technology and random cloning methodologies. The application of high-throughput sequencing technology is now enabling access to both known and previously unknown transcripts in natural com munities. We present a study of a complex marine meta...

Each metagenome study of a complex habitat is accompanied by lots of unknowns as so far the depth of sequencing is usually insufficient to reveal the entire microbial community of an ecosystem. The probably easiest way of extracting meaningful information is the comparison with existing data, analogous to that of genome comparisons. However, the complexity within the analysis chain of a single metagenome annotation is topped by the difficulties that the integration of heterogeneously analyzed...
