- Fine particulate matter (PM2.5) is a well-established risk factor for public health. To support both health risk assessment and epidemiological studies, data are needed on spatial and temporal patterns of PM2.5 exposures. This review article surveys publicly available exposure datasets for surface PM2.5 mass concentrations over the contiguous U.S., summarizes their applications and limitations, and provides suggestions on future research needs. The complex landscape of satellite instruments, model capabilities, monitor networks, and data synthesis methods offers opportunities for research...AuthorsMinghui Diao, Tracey Holloway, Seohyun Choi, Susan O'Neill, Mohammad Z.

- Salvage logging after forest disturbances is a controversial but common practice, yet it remains relatively poorly studied, particularly after windstorms within deciduous forests. Here, we present results from the first growing season following salvage logging on four gaps (3.5–6 ha) created by a 2012 tornado. While salvage logging shifted the distribution of stem heights to smaller sizes, it increased woody species seedling diversity by 33% and total plant richness and diversity by 20%. Salvaging did not alter or homogenize community composition. These short-term differences in richness...AuthorsJacob B. Slyder, John W. Wenzel, Alejandro A. Royo, Michelle Elise Spicer, Walter P.

- Short- and long-term impacts of wildland fires on forest floor properties and erosion potential were examined at three locations in the Central Appalachian region, U.S.A. In 2018, two wildfires were investigated within six months of burning on the George Washington–Je erson National Forest (GWJNF) in Bland County, Virginia and the Monongahela National Forest (MNF) in Grant County,West Virginia. An additional wildfire was studied eight years post-fire on the Fishburn Forest (FF) in Montgomery County, Virginia. A 2018 prescribed fire was also studied within six months of burning on the MNF...AuthorsEmma Georgia Thompson, Thomas Adam Coates, Wallace Michael Aust, Melissa Thomas-Van GundyKeywordsSourceForestsYear2019
- Rapid global climate change is resulting in novel abiotic and biotic conditions and interactions. Identifying management strategies that maximize probability of long‐term persistence requires an understanding of the vulnerability of species to environmental changes. We sought to quantify the vulnerability of Kirtland's Warbler (Setophaga kirtlandii), a rare Neotropical migratory songbird that breeds almost exclusively in the Lower Peninsula of Michigan and winters in the Bahamian Archipelago, to projected environmental changes on the breeding and wintering grounds. We developed a population...AuthorsDonald J. Brown, Deahn Donner, Christine A. Ribic, Carol I BocettiKeywordsSourceEcology and EvolutionYear2019

- The emerald ash borer (EAB) was first detected in North America in 2002, and since its introduction, this invasive pest has killed millions of ash trees. While EAB kills native North American ash trees in all settings, its impacts have been especially large in urban areas where ash has been a dominant street tree, especially in residential areas. While some management costs, such as insecticide treatment, tree removal, or tree replacement, are relatively straightforward to compute, the impact that EAB has had on residential property values is less clear. To better understand the economic...AuthorsXiaoshu Li, Tom Holmes, Kevin J. Boyle, Ellen V Crocker, C. Dana NelsonSourceForestsYear2019

- We quantified the sum of daily mean temperature above 0 °C and modeled incubation duration using water temperature data collected at 12 coho salmon (Oncorhynchus kisutch) spawning sites during two incubation periods with cool, snow dominant conditions and three incubation periods with anomalously warm, rain-transitional conditions, a proxy for a future climate scenario. Warmer water temperatures during warm–rain-transitional winters yielded a 58-day reduction in the median duration of egg incubation; however, the magnitude of change at individual sites varied widely and was controlled by...AuthorsLuca A.
