North Temperate Lakes site, station Allequash Lake, study of animal abundance of Percina caprodes in units of numberPerEffort 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 North Temperate Lakes (NTL) contains animal abundance of Percina caprodes measurements in numberPerEffort units and were aggregated to a yearly timescale.

Data from: A new species of logperch endemic to Tennessee (Percidae: Etheostomatinae: Percina)
Percina apina, the Tennessee Logperch, is described as a new species endemic to Tennessee and distributed in the Duck River system and Whiteoak Creek. The earliest collection records for Percina apina date to 1971 and the species was identified as Percina burtoni, the Blotchside Logperch. A phylogenetic analysis of mitochondrial DNA (mtDNA) published in 2006 showed that populations identified as Percina burtoni in the Duck River system and Whiteoak Creek were a new and undescribed species. In this study, we test the hypothesis that Percina burtoni is composed of multiple species through analyses of mtDNA, nuclear genetic variation, and traditional meristic trait morphology. Our analyses of morphological divergence, nuclear genotypes, mtDNA gene trees, and comparisons with other sister species pairs of logperches confirm the distinctiveness of Percina apina. Morphologically, Percina apina is distinguished from Percina burtoni through higher average numbers of lateral line scales (93.1 versus 89.9); pored lateral line scales (91.6 versus 88.8); rows of transverse scales (38.1 versus 33.6); and scales around the caudal peduncle (36.2 versus 33.5). The two species also differ in patterns of pigmentation; the lateral blotches in Percina apina are typically wider than high, whereas the blotches tend to be higher than wide in Percina burtoni. We recommend that future species descriptions of North American freshwater fishes leverage available genetic resources and include molecular phylogenetic assessments in analyses of taxon distinctiveness. In addition, we advocate the deposition of morphological data used in species descriptions to online data repositories to ensure that other researchers are able to evaluate and modify hypotheses of species delimitations.

The CR is separated into an extended termination-associated sequence domain (ETAS), a core domain, and a conserved sequence block (CSB) domain. The underlined portion denotes the long tandem repeat sequence within the ETAS domain. The blue-green highlighted sequence represents the ETAS 1 region while the blue highlighted sequence represents the ETAS 2 region. Nucleotides in green, yellow and pink correspond to the F-box, E-box and D-box regions within the central domain, respectively. Nucleotides in cyan, red and dark green correspond to the CSB-1, CSB-2 and CSB-3 regions, respectively.
