Arctic LTER site, station Fertilized reach of Kuparuk River, study of animal denstiy of Chironomid in units of numberPerMeterSquared on a yearly timescale
The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Arctic LTER (ARC) contains animal denstiy of Chironomid measurements in numberPerMeterSquared units and were aggregated to a yearly timescale.

Chironomid-based temperature reconstruction from Burgäschisee, Switzerland
<p>The data herein presents a new chironomid record and associated chironomid-based temperature reconstruction covering the time interval 18,000-14,000 cal. BP from the lacustrine sediments of a kettle hole lake Burgäschisee, Switzerland. Chironomid assemblages show ecological turnover beginning 1,300 years before the onset of the Oldest Dryas / <span>Bølling</span> transition at ca. 14,700 cal. BP and associated increases in chironomid-based temperature reconstructions. These data also include non-chironomid invertebrate remains, including Ceratopogonidae, Daphnia and Ephemeroptera as well as Characean oospores.</p>
Data from: Quorum-sensing signaling by chironomid egg masses' microbiota affects haemagglutinin/protease (HAP) production by Vibrio cholerae
<p><i>Vibrio cholerae</i>, the causative agent of cholera, is commonly isolated, along with other bacterial species, from chironomid insects (<i>Diptera: Chironomide</i>). Nevertheless, its prevalence in the chironomid egg masses' microbiota is less than 0.5%. <i>V. cholerae</i> secretes haemagglutinin/protease (HAP) that degrades the gelatinous matrix of chironomid egg masses and prevents hatching. Quorum sensing (QS) activates HAP production in response to accumulation of bacterial autoinducers (AIs). Our aim was to define the impact of chironomid microbiota on HAP production by <i>V. cholerae</i>. To study QS signaling, we used<i> V. cholerae</i> bioluminescence reporter strains (QS-proficient O1 El-Tor wild type and QS-deficient mutants) and different bacterial species that we isolated from chironomid egg masses. These egg mass isolates, as well as a synthetic AI-2, caused an enhancement in <i>lux</i> expression by a <i>V. cholerae</i> QS-deficient mutant. The addition of the egg mass bacterial isolate supernatant to the QS-deficient mutant also enhanced HAP production and egg mass degradation activities. Moreover, the <i>V. cholerae</i> wild type strain was able to proliferate using egg masses as their sole carbon source while the QS-deficient was not. The results demonstrate that members of the chironomid bacterial consortium produce external chemical cues that, like AI-2, induce expression of the<i> hapA </i>gene in <i>V. cholerae</i>. Understanding the interactions between <i>V. cholerae</i> and the insects' microbiota may help uncover the interactions between this pathogen and the human gut microbiota.</p>
