The growing body of metagenomic data offers the possibility for creating longer consensus assemblies for ecosystems of interest as a community resource. We tested this concept by performing a co-assembly of metagenome and metatranscriptome data from five independent studies of biological soil crust communities in the southwestern United States.
Data from: Human impacted landscapes facilitate hybridization between a native and an introduced treeSean M. Hoban, Tim S. McCleary, Scott E. Schlarbaum, Sandra L. Anagnostakis & Jeanne Romero-Severson
Spatial and temporal dynamics of hybridization, in particular the influence of local environmental conditions, are well studied for sympatric species but less is known for native-introduced systems, especially for long-lived species. We used microsatellite and chloroplast DNA markers to characterize the influence of anthropogenic landscapes on the extent, direction, and spatial distribution of hybridization between a native North American tree Juglans cinerea (butternut) and an introduced tree Juglans ailantifolia (Japanese walnut) for 1363 trees at...
Nitrogen enrichment stimulates wetland plant responses whereas salt amendments alter sediment microbial communities and biogeochemical responsesMary Donato, Olivia Johnson, Blaire Steven & Beth Lawrence
Freshwater wetlands of the temperate north are exposed to a range of pollutants that may alter their function, including nitrogen (N)-rich agricultural and urban runoff, seawater intrusion, and road salt contamination, though it is largely unknown how these drivers of change interact with the vegetation to affect wetland carbon (C) fluxes and microbial communities. We implemented a full factorial mesocosm (378.5 L tanks) experiment investigating C-related responses to three common wetland plants of eastern North...
Increasing agricultural habitat reduces solitary bee offspring number and weight in apple orchards through reduced floral diet diversity and increased fungicide riskMary Centrella, Laura Russo, Natalia Moreno-Ramirez, Brian Eitzer, Maria Van Dyke, Bryan Danforth & Katja Poveda
1. Threats to bee pollinators such as land use change, high pesticide risk, and reduced floral diet diversity are usually assessed independently, even though they often co-occur to impact bees in agroecosystems. 2. We established populations of the non-native mason bee O. cornifrons at 17 NY apple orchards varying in proportion of surrounding agriculture and measured floral diet diversity and pesticide risk levels in the pollen provisions they produced. We used path analysis to test...
Most subterranean animals are assumed to have evolved from surface ancestors following colonisation of a cave system, however very few studies have raised the possibility of ‘subterranean speciation’ in underground habitats (i.e. obligate cave-dwelling organisms (troglobionts) descended from troglobiotic ancestors). Numerous endemic subterranean diving beetle species from spatially-discrete calcrete aquifers in Western Australia (stygobionts) have evolved independently from surface ancestors; however, several cases of sympatric sister species raises the possibility of subterranean speciation. We tested...
Patterns of mosquito and arbovirus community composition and ecological indexes of arboviral risk in the northeast United StatesJoseph McMillan, Philip Armstrong & Theodore Andreadis
Background: In the northeast United States (U.S.), mosquitoes transmit a number of arboviruses, including eastern equine encephalitis, Jamestown Canyon, and West Nile that pose an annual threat to human and animal health. Local transmission of each virus may be driven by the involvement of multiple mosquito species; however, the specificity of these vector-virus associations has not been fully quantified. Methodology: We used long-term surveillance data consistently collected over 18 years to evaluate mosquito and arbovirus...
Mosquito larval and adult collections in Stratford and Milford, Connecticut, United States 2019 - 2020Joseph McMillan
Background Mosquito larval control through the use of insecticides is the most common strategy for suppressing West Nile virus (WNV) vector populations in Connecticut (CT), United States. To evaluate the ability of larval control to reduce entomological risk metrics associated with WNV, we performed WNV surveillance and assessments of municipal larvicide application programs in Milford and Stratford, CT in 2019 and 2020. Each town treated catch basins and non-basin habitats (Milford only) with biopesticide products...
Data from: Planting of neonicotinoid-treated maize poses risks for honey bees and other non-target organisms over a wide area without consistent crop yield benefitChristian H. Krupke, Jeffrey D. Holland, Elizabeth Y. Long & Brian D. Eitzer
Neonicotinoid insecticides are routinely used as seed treatments on most grain and oilseed crops in the USA, yet the extent and likelihood of spread of insecticide residues during planting has not previously been quantified. Honey bees, Apis mellifera, are highly mobile and highly sensitive to neonicotinoid residues, presenting an opportunity to estimate non-target exposures to neonicotinoids in mobile insects. We measured neonicotinoid dust drift during maize sowing and used sites of maize fields, apiary locations...
