Dennis Lapointe
2015, American Entomologist (61) 192-192
In 1826, the paradise that was the Hawaiian Islands was changed forever when the first mosquito species was accidentally introduced to the island of Maui. Though it has not lived up to its potential as a vector of human disease in the islands, Culex quinquefasciatus and the avian pathogens it transmits laid waste to perhaps...
Soil bacterial and fungal community responses to nitrogen addition across soil depth and microhabitat in an arid shrubland
Rebecca C. Mueller, Jayne Belnap, Cheryl R. Kuske
2015, Frontiers in Microbiology (6)
Arid shrublands are stressful environments, typified by alkaline soils low in organic matter, with biologically-limiting extremes in water availability, temperature, and UV radiation. The widely-spaced plants and interspace biological soil crusts in these regions provide soil nutrients in a localized fashion, creating a mosaic pattern of plant- or crust-associated...

Seasonally-dynamic presence-only species distribution models for a cryptic migratory bat impacted by wind energy development
Mark A. Hayes, Paul M. Cryan, Michael B. Wunder
2015, PLoS ONE (10)
Understanding seasonal distribution and movement patterns of animals that migrate long distances is an essential part of monitoring and conserving their populations. Compared to migratory birds and other more conspicuous migrants, we know very little about the movement patterns of many migratory bats. Hoary bats (Lasiurus cinereus), a cryptic, wide-ranging,...
Not to put too fine a point on it - does increasing precision of geographic referencing improve species distribution models for a wide-ranging migratory bat?
Mark A. Hayes, Katharine Ozenberger, Paul M. Cryan, Michael B. Wunder
2015, Acta Chiropterologica (17) 159-169
Bat specimens held in natural history museum collections can provide insights into the distribution of species. However, there are several important sources of spatial error associated with natural history specimens that may influence the analysis and mapping of bat species distributions. We analyzed the importance of geographic referencing and error...

Estimation of river and stream temperature trends under haphazard sampling
Brian R. Gray, Vyacheslav Lyubchich, Yulia R. Gel, James T. Rogala, Dale M. Robertson, Xiaoqiao Wei
2015, Statistical Methods & Applications (25) 89-105
Long-term temporal trends in water temperature in rivers and streams are typically estimated under the assumption of evenly-spaced space-time measurements. However, sampling times and dates associated with historical water temperature datasets and some sampling designs may be haphazard. As a result, trends in temperature may be confounded with trends in...
Habitat, not resource availability, limits consumer production in lake ecosystems
Nicola Craig, Stuart E. Jones, Brian Weidel, Christopher T. Solomon
2015, Limnology and Oceanography (60) 2079-2089
Food web productivity in lakes can be limited by dissolved organic carbon (DOC), which reduces fish production by limiting the abundance of their zoobenthic prey. We demonstrate that in a set of 10 small, north temperate lakes spanning a wide DOC gradient, these negative effects of high DOC concentrations on...
