California Current Ecosystem site, station San Diego County, CA (FIPS 6073), study of population employed at farms (percent of total) in units of percent 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 California Current Ecosystem (CCE) contains population employed at farms (percent of total) measurements in percent units and were aggregated to a yearly timescale.

White-tailed Deer Population Study, 1962-2008, Adirondack Long-Term Ecological Monitoring Program by Adirondack Ecological Center of the State University of New York College of Environmental Science and Forestry, Newcomb, New York, USA
From 1962-2008, White-tailed deer (Odocoileus virginianus) were studied at the SUNY ESF Huntington Wildlife Forest (HWF) and adjacent private and public lands in Essex and Hamilton Counties, New York, USA. Social group membership, migration and dispersal, reproductive biology, and many other objectives were studied over the course of the study period. Deer were captured, individually marked with ear tags or streamers, fitted with radio collars (later, GPS collars), and released to be tracked for a variety of research objectives. Deer were located by visual observation, recapture, and/or their location was estimated with ground, air or tower-based radio telemetry. Physical condition of deer was recorded at capture and at subsequent recapture or visual observation select variables were documented (e.g., deer group size; presence of fawns with does). Physiological, demographic, social organization, home range and behavior data were collected. HWF is a no-hunting area but deer could be harvested if they moved to huntable parts of the study area; there was a managed hunt on HWF in 1966-1970 and in 1984 to meet deer density and forest management objectives at that time. Unmarked deer were incorporated into the dataset if they were roadkilled, harvested or otherwise encountered during field activity; these deer did not receive individual identifications but may have been incorporated into select projects.
Variability in soil and litter arthropod populations in the Soil Freezing Study plots at the Hubbard Brook Experimental Forest, 2009-2010
Climate models for the northeastern United States (U.S.) over the next century project an increase in air temperature between 2.8 and 4.3 °C and a decrease in the average number of days per year when a snowpack will cover the forest floor. Warmer temperatures may benefit some litter arthropods by allowing them to expand their ranges and to increase their rates of reproduction. However, a reduction in snowpack depth and duration could offset these changes and lead to increased arthropod mortality because the snowpack plays an important role in insulating arthropods from freezing temperatures. We evaluated these potential changes by measuring arthropod abundance in the Soil Freezing Study plots at the Hubabard Brook Experimental Forest. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
Linking individual physiological indicators to the productivity of fish populations: A case study of Atlantic herring
<p>Raw data for i) heart rate measurements of Atlantic herring larvae reared at three different temperatures (7, 11 and 15°C); ii) compilation of Baltic herring larval growth rates measured in the field and in the laboratory; and iii) time series of thermal estimates (derived from satellite sea surface temperatures) in Greifswald Bay (Baltic Sea) between 1992 and 2017, as well as three herring productivity proxies in the area: weekly larval abundance in Greifswald Bay (one of the major spawning grounds), 1 yr-old juvenile abundance in the western Baltic basin, and the recruitment estimate from the International Council for the Exploration of the Sea (ICES) Herring Assessment Working Group for the Area South of 62°N.</p>

Data from: The effects of climate warming on the migratory status of early summer populations of Mythimna separata(Walker) moths: a case-study of enhanced corn damage in central-northern China, 1980 - 2016
Mythimna separata (Walker) moths captured in light-traps were monitored in Luohe, central-northern China, from 1980 to 2016. Annual average temperature recorded an increase of 0.298 oC/10 years in this region in the period. Our results indicate that a rising Apr and May avarage temprature and earlier occurrences of days recording the highest day temperature (30℃) caused an advanced peak and increasing proportion of high ovarian development levels of first generation females in earlier summers. Results using Johnson's formulation of 'oogenesis-flight syndrome' indicate that increasing sexual maturity proportion has resulted in more emigrant individuals in the local first generaton moth becoming residents, and then increased individuls repidly in the local second generation moth since 2006. Consequences of this action have a boom in corn damage since 2007 in this region. Advanced peak dates of the first and second generation moth revealed the same response to increasing average monthly temperatures in the monitoring period. Increasing temperatures, the avarage May temperature exceeds or equal to 22℃, during the early 2000's may represent a physiological threshold for M. separata development. Our results suggest that climate warming may impact M. separata migratory status and cause a problem of crop production in this region.
Data from: Drivers of spatiotemporal variation in survival in a flyway population: a multi-colony study
<p>1. Spatio-temporal variation in population dynamics of migratory populations is shaped by exposure to different environments during the annual cycle. Hence, exposure to similar environments should translate into synchrony in vital rates. Despite a wide-ranging breeding population, the Baltic/Wadden Sea flyway population of eiders (<i>Somateria m. mollissima</i>) shares wintering grounds in the southern Baltic Sea, inner Danish waters and the Wadden Sea; different colonies within this flyway population are therefore likely to exhibit some degree of synchrony in vital rates.</p> <p>2. Here we used capture-recapture-recovery data to investigate the impact of hunting, winter climate (the North-Atlantic Oscillation Index), winter temperature, nitrogen runoff, autumn-winter body condition of blue mussels <i>Mytilus </i>spp., natural predation and epidemic disease (avian cholera) on annual survival of adult females in ten study colonies distributed between the Netherlands and Finland. Moreover, we tested how the degree of similarity in spatial winter distributions affected the degree of similarity in annual survival among colonies.</p> <p>3. None of the covariates universally affected female survival. While the quality of blue mussels in the wintering area explained almost 40 % of the variation in survival of eiders breeding on Christiansø in the south-western Baltic Sea, incidence of epidemic disease explained > 60 % in two affected colonies. Furthermore, the spatial winter distribution did not appreciably influence annual survival rates in these ten colonies.</p> <p>4. The lack of universal effects of spatial winter distribution and winter conditions on survival suggests that local breeding conditions may be more important, and hence prime targets for conservation efforts. Better monitoring of e.g. food quality, predation pressure and epidemic disease at the time of breeding could be the key to better understand the population dynamics in this endangered flyway population.</p>
