Biocomplexity at North Temperate Lakes LTER; Whole Lake Manipulations: Exotic Crayfish Removal 2001 - 2010
As part of a whole-lake experiment to overexploit a rusty crayfish (O. rusticus) population in Sparkling Lake, Vilas County, Wisconsin, crayfish were intensively trapped and removed from the lake from early to mid June through late August starting from 2001through 2008. From 2001 to 2004, removal traps were concentrated on the southern and western shorelines of the lake, where cobble is prevalent and catch rates were highest. Starting in 2005, additional traps were used and trapping effort was spread around the entire perimeter of the lake. Additional traps (perimeter) were set on standard arrays at 43 sites around the lake at 1 m deep from 2001 through 2006. In 2001 and 2003, traps (depth transect) were also set on standard arrays that ranged from 0.5 to 12 m deep. From 2001-2004, trap_site corresponds to one of the 43 standard sites where the trap was set. For perimeter and depth transect trapping, one trap is set at a trap site. During the removal trapping, 10 traps are set at each of the standard trapping sites. The trap_id identifier contains more information about the spatial location of a removal trap. From 2005-2008, traps were numbered sequentially moving clockwise around the lake starting at site 1, with no reference to standard trapping sites from previous years. In 2009, traps were set at the 43 standard sites. Capture data were recorded in 2009 but crayfish were not removed. Daily catch statistics: The data table Crayfish Daily Capture Summary provides the number of each species captured each day in the perimeter and removal traps. Also included are data on the number of traps pulled on that day and the number of trap_days these traps represent. These data can be used to calculate capture rates. The data table Crayfish Daily Capture by Station has daily catch statictics for 2009 at the capture site level. Crayfish length measurements: Prior to 2005, a crayfish that was measured could be associated with the specific trap in which it was captured. These l
Density-dependent effects of exotic brook trout on aquatic communities in mountain lakes revealed by environmental DNA and morphological taxonomy
Invasion of non-native fishes threatens freshwater biodiversity worldwide. Yet, detailed estimates of population demography for invasive species, that estimate population size and body size of the invasive species, are rarely integrated in evaluating aquatic community responses. Our study capitalized on detailed brook trout population demographic data collected for a replicated whole lake ecosystem experiment involving experimental harvesting of exotic brook trout in nine mountain lakes. We applied environmental DNA (eDNA) metabarcoding and morphological taxonomy to examine the response of crustacean zooplankton and macroinvertebrate communities to gradients in brook trout effective density and lake elevation. Density-dependent effects of brook trout on crustacean zooplankton and macroinvertebrate communities were detected even decades after their first introductions (between 1926 and 1980). However, they were moderated by environmental factors such as elevation, lake maximum depth and dissolved organic carbon. Elevation was important in structuring crustacean zooplankton and macroinvertebrate community composition. While there were differences in explanatory variables when describing communities characterized by eDNA metabarcoding and morphological taxonomy, the principal environmental factors that structured the communities were similar. Our paper highlights persisting density-dependent impacts of exotic trout on invertebrate communities even decades after first introduction, and it considers the conservation implications for lake restoration.

Data for "Pollinator Conservation Paradox: Exotic Forbs Support Native Pollinators Under Global Changes" by Nelson, Seabloom and Borer 2025, California grasslands, 2023-2024
Data for analysis on how plant provenance mediates plant-pollinator interaction responses to fertilization and herbivore exclusion, associated with Nelson, Seabloom, and Borer 2025. Data on pollinator visitation and floral abundance were collected in plots that received factorial experimental treatments of combined nitrogen, phosphorus and potassium with micronutrients by herbivore exclusion fencing in three California grasslands in 2023-2024.

Data from: Native-exotic richness relationship in Michigan prairies
<p>A better understanding of factors underlying positive correlations between native and exotic species richness, a pattern that is nearly ubiquitous at large scales in plant communities, may help managers modify these correlations to favor native plant species during restoration. Across 29 tallgrass prairie sites restored through seed sowing onto former agricultural lands, we examined whether the relationship between native and exotic richness is: 1) altered by management, such as seed additions and prescribed fire, 2) controlled instead by environmental conditions and successional processes, or 3) altered by management in certain environments and not in others.</p> <p>Two datasets. Both contain exotic and native plant SR across several prairie restorations, as well as data on seed mix properties (mix richness, seeding rate), fire frequency, age of restoration. "BassettNativeExoticData" contains data on additional factors that influence invasion: environmental factors (PCA of surrounding land use, tillage history, plant biomass, CV of plant biomass, total vegetative cover, PCA of soil characteristics, CV of soil water holding capacity, edge-area ratio). "BassettNativeExoticData.mngmt" contains detailed data on seed mixes (proportions of functional groups in seed mixes). Both raw and standardized ([value-mean]/sd) values for most data.</p>
