Data from Pliant pathogens: Estimating viral spread when confronted with new vector, host, and environmental conditions
To determine the effects of new conditions (host, vector, and nutrient) on pathogen spread rate, we introduced a vector-borne viral plant pathogen, Barley Yellow Dwarf Virus PAV (BYDV-PAV) into hosts, vectors, and host nutrient supplies that it had not encountered for thousands of viral generations. We quantified pathogen prevalence over the course of two serial inoculations under the new conditions.
Ruffed grouse (Bonasa umbellus) drumming surveys, 1987-2017, Adirondack Long-Term Ecological Monitoring Program Project No. 9 by Adirondack Ecological Center of the State University of New York College of Environmental Science and Forestry, Newcomb, New York. Environmental Data Initiative
The objective is to document long-term population trends of ruffed grouse in a northern hardwood ecosystem. The survey area is the Huntington Wildlife Forest, a 6,000 ha field station which receives no hunting pressure. Routes are surveyed starting an hour prior to sunrise on 2-5 mornings each year between April 14 and May 9 (occasionally later), on days when wind and rain are minimal to absent. Counts are standardized relative to weather conditions and timing. Observers count the number of individual ruffed grouse heard drumming (""drummers"") at 32-50 route stations during a 4-minute period. Trends at stations over time as well as overall drummer index are calculated and compared to independent datasets.
Nitrogen and Carbon cycling data in 10 urban afforestation sites in New York City 2018
The data includes soil microbial processes of carbon (C) and N in 10 afforestation sites in New York City as part of the MillionTreesNYC initiative (MTNYC) of the New York City Department of Parks and Recreation. Long-term research plots were established between 2009-2011 in municipal parks: Alley Pond, Canarsie, Ft. Totten, Clearview, Conference House, Clove Lakes, Marine Park (3 sites), and Pelham Bay. Sites were planted with low (two tree species) and high diversity (six tree species) treatments. More detailed description of sites and MTNYC project is provided by Downey et al. (2021). In 2018, 1 m soil cores were collected from plots at each site and analyzed for microbial biomass C and N, basal respiration, potential net N mineralization and nitrification, denitrification potential, soil inorganic N, and total soil N. Laboratory methods followed those used by Raciti et al. (2011a,b), and Groffman et al. (1999).
Rodent Parasite Data for the Sevilleta National Wildlife Refuge, New Mexico (1990-1998)
The 100,000 ha Sevilleta National Wildlife Refuge (SNWR) in central New Mexico lies in a transition zone that straddles several major biomes of the Southwest, including Great Basin Shrub-Steppe, Mogollon Pinon-Juniper Woodland, Great Plains Grassland and Chihuahuan Desert. During 9 years, (1990-1998), collaborating with the University of New Mexico's Long Term Ecological Research (LTER) program, 3,235 rodents (28 species in 4 families) were collected and identified from permanent collecting sites on the 3 major habitat types (grassland, desert/creosote, woodland) on the SNWR. Hosts were necropsied for endoparasites (protozoa [coccidia], helminths) and some ectoparasites. We identified and analyzed all the parasites found in these hosts. By 1998, we had in place the means to easily identify and moniter the parasites from all mammalian hosts caught on the LTER Phase II grant.This is not just another parasite survey; the data we collected was unique for several reasons: 1) This was the first complete inventory of a natural assemblage of parasites from all mammalian (rodent) hosts in 3 different communities, each from a distinctly defined geographic locality (habitat type) over the period of a decade, and beyond; 2) This study was part of a multidisciplinary approach to address conceptual issues of climate change on ecosystem structure and function at multiple scales (individuals, communities, etc) and correlative data from these related studies will strengthen and contribute to the robustness of this data set; 3) As the only parasite study on any of the LTER projects nationwide, it provided an ideal model, and perhaps incentive for parallel longterm studies of parasite communities to be examined in a variety of other habitat types, and from a variety of different perspectives, and other LTER sites in the network.Upon completing the work, we were able to use these long-term data to try to understand the dynamics of natural host-parasite assemblages. Hypotheses were then
Allometric Ant Foraging Data from the Sevilleta National Wildlife Refuge, New Mexico (2003)
The allometric ant foraging data was collected to test the allometric ant foraging model proposed by Jun et al. (2003). Key variables are the number of foragers in the colony, the time of an average foraging trip for the colony and the average distance a forager travels to collect a seed. Data on Pogonomyrmex rugosus and Pogonomyrmex maricopa were collected at the Sevilleta.
Pino Gate Prairie Dog Study at the Sevilleta National Wildlife Refuge, New Mexico: Mound-Scale Lizard Data (2000-2002)
Keystone species have large impacts on community and ecosystem properties, and create important ecological interactions with other species. Prairie dogs (Cynomys spp.) and banner-tailed kangaroo rats (Dipodomys spectabilis) are considered keystone species of grassland ecosystems, and create a mosaic of unique habitats on the landscape. These habitats are known to attract a number of animal species, but little is known about how they affect lizard communities. Our research evaluated the keystone roles of prairie dogs and kangaroo rats on lizards at the Sevilleta National Wildlife Refuge in central New Mexico, USA. We evaluated the impacts of these rodents on lizard communities in areas where prairie dogs and kangaroo rats co-occurred compared to areas where each rodent species occurred alone. Our results demonstrate that prairie dogs and kangaroo rats have keystone-level impacts on these lizard communities. Their burrow systems provided important habitats for multiple lizard species, especially the lesser earless lizard (Holbrookia maculata). At the landscape-scale, the total number of lizards was two-times greater on the where both prairie dogs and banner-tailed kangaroo rats co-occurred than where only kangaroo rats occurred.
Gunnison's Prairie Dog Relocation Project: Vegetation Cover Data from the Sevilleta National Wildife Refuge, New Mexico (2005-2013)
Prairie dogs are keystone species that impact both animals and plants in grassland habitats. They are a food resource for secondary consumers such as badgers, foxes, and raptors. Also, the mounds that they construct are home to many arthropod and reptile species that otherwise might not survive in grasslands. Both Gunnison’s and black-tailed prairie dogs can increase the number of plant species in grasslands and landscape heterogeneity with their ecosystem engineering that creates disturbed patches on the landscape. Gunnison’s prairie dogs, which were native herbivores at the Sevilleta National Wildlife Refuge (NWR) before their populations disappeared, were reintroduced at the Sevilleta NWR in 1997, 2005, and 2008. In 1998, a Gunnison’s prairie dog colony naturally established along the northern border on the east side of the Refuge. The naturally occurring colony and the colony that was reintroduced in 1997 have since then severely declined or gone locally extinct. Still, with the removal of cattle from the Sevilleta in 1973, the reintroductions of Gunnison’s prairie dogs in 2005 and 2008 provides an interesting opportunity to study how a native keystone herbivore affects a grassland habitat without the pressures and competition from livestock.
Monsoon Rainfall Manipulation Experiment (MRME) Carbon Dioxide Data from the Sevilleta National Wildlife Refuge, New Mexico (7/2007-8/2009)
The Monsoon Rainfall Manipulation Experiment (MRME) is to understand changes in ecosystem structure and function of a semiarid grassland caused by increased precipitation variability, which alters the pulses of soil moisture that drive primary productivity, community composition, and ecosystem functioning. The overarching hypothesis being tested is that changes in event size and variability will alter grassland productivity, ecosystem processes, and plant community dynamics. In particular, we predict that many small events will increase soil CO2 effluxes by stimulating microbial processes but not plant growth, whereas a small number of large events will increase aboveground NPP and soil respiration by providing sufficient deep soil moisture to sustain plant growth for longer periods of time during the summer monsoon.
