Nitrogen enrichment stimulates wetland plant responses whereas salt amendments alter sediment microbial communities and biogeochemical responses

Mary 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 risk

Mary 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...

Evidence for speciation underground in diving beetles (Dytiscidae) from a subterranean archipelago

Barbara Langille, Josephine Hyde, Kathleen Saint, Tessa Bradford, Danielle Stringer, Simon Tierney, William Humphreys, Andrew Austin & Steven Cooper
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 States

Joseph 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...
