New species Lopharia resupinata and L. sinensis are described and illustrated. Lopharia resupinata, from south-eastern China, is closely related to L. ayresii, and L. sinensis, from northern China, is related to L. cinerascens and L. mirabilis. Lopharia mirabilis specimens from temperate to tropical areas with varied hymenophore...AuthorsShi-Liang Liu, Karen K.

- In the United States, tornadoes cause significant damage and result in many injuries and deaths. Although the development and use of tornado safe rooms have helped decrease the human toll associated with these events, the cost of these structures is often too high for many that could benefit from their use. The development of a nonproprietary residential tornado safe room constructed from commodity wood building products, buildable by a local contractor or do-it-yourselfer, and adaptable to existing homes, could lower the cost of these structures and result in more widespread use. This...AuthorsRobert H. Falk, James BridwellKeywordsSourceGen. Tech. Rep. FPL-GTR-253. Madison, WI: U.S. Department of Agriculture, Forest Service, Forest Products Laboratory. 1-8.Year2018
- Through litter decomposition enormous amounts of carbon is emitted to the atmosphere. Numerous large-scale decomposition experiments have been conducted focusing on this fundamental soil process in order to understand the controls on the terrestrial carbon transfer to the atmosphere. However, previous studies were mostly based on site-specific litter and methodologies, adding major uncertainty to syntheses, comparisons and metaanalyses across different experiments and sites. In the TeaComposition initiative, the potential litter decomposition is investigated by using standardized substrates...AuthorsAndré-Jean Francez, Andrea Fischer, Andreas Bohner, Andrey Malyshev, Andrijana Andrić, Andy Smith, Angela Stanisci, Anikó Seres, Anja Schmidt, Anna Avila, Anne Probst, Annie Ouin, Anzar A.

- Violence is a widespread problem that affects the physical, mental, and social health of individuals and communities. Violence comes with an immense economic cost to its victims and society at large. Although violence interventions have traditionally targeted individuals, changes to the built environment in places where violence occurs show promise as practical, sustainable, and high-impact preventive measures. This review examines studies that use quasi-experimental or experimental designs to compare violence outcomes for treatment and control groups before and after a change is implemente...AuthorsMichelle Kondo, Elena Andreyeva, Eugenia C.

- Vacant and blighted urban land is a widespread and potentially risky environmental condition encountered by millions of people on a daily basis. About 15% of the land in US cities is deemed vacant or abandoned, an area roughly the size of Switzerland. In a citywide cluster randomized controlled trial, we investigated the effects of standardized, reproducible interventions that restore vacant land on the commission of violence, crime, and the perceptions of fear and safety. Quantitative and ethnographic analyses were included in a mixed-methods approach to more fully test and explicate our...AuthorsCharles C. Branas, Eugenia South, Michelle Kondo, Bernadette C.

- Building resilience to natural disturbances is a key to managing forests for adaptation to climate change. To date, most climate adaptation guidance has focused on recommendations for frequent-fire forests, leaving few published guidelines for forests that naturally experience infrequent, stand-replacing wildfires. Because most such forests are inherently resilient to stand-replacing disturbances, and burn severity mosaics are largely indifferent to manipulations of stand structure (i.e., weather-driven, rather than fuel-driven fire regimes), we posit that pre-fire climate adaptation...AuthorsJoshua S.

- After emerald ash borer (EAB), Agrilus planipennis Fairmaire, was discovered in the United States, a classical biological control program was initiated against this destructive pest of ash trees (Fraxinus spp.). This biocontrol program began in 2007 after federal regulatory agencies and the state of Michigan approved release of three EAB parasitoid species from China: Tetrastichus planipennisi Yang (Eulophidae), Spathius agrili Yang (Braconidae), and Oobius agrili Zhang and Huang (Encyrtidae). A fourth EAB parasitoid, Spathius galinae Belokobylskij (Braconidae) from Russia, was approved...AuthorsJian Duan, Leah Bauer, Roy van Driesche, Juli GouldKeywordsSourceForests. 9(3): 142. 17 p.Year2018
- U.S. urban land increased from 2.6% (57.9 million acres) in 2000 to 3.0% (68.0 million acres) in 2010. States with the greatest amount of urban growth were in the South/Southeast (TX, FL, NC, GA and SC). Between 2010 and 2060, urban land is projected to increase another 95.5 million acres to 163.1 million acres (8.6%) with 18 states projected to have an increase of over 2 million acres. Overall, there are an estimated 5.5 billion trees (39.4% tree cover) in urban areas nationally that contain 127 million acres of leaf area and 44 million tons of dry-weight leaf biomass. Annually, these...AuthorsDavid J. Nowak, Eric J. GreenfieldKeywordsSourceJournal of Forestry. 116(2): 164-177.Year2018
- The capacity to forecast climate and land-use driven changes to runoff, soil erosion and sediment transport in the tropics is hindered by a lack of long-term data sets and model study systems. To address these issues we utilized three watersheds characterized by similar shape, geology, soils, vegetation cover, and land use arranged across a 900 mm gradient in mean annual rainfall (MAR). Using this space-for-time design, we quantified suspended sediment (SS) and particulate organic carbon (POC) export over 18 months to examine how large-scale climate trends (MAR) affect sediment supply and...AuthorsAyron M.

- Traditional analysis in population genetics evaluates differences among groups of individuals and, in some cases, considers the effects of distance or potential barriers to gene flow. Genetic variation of organisms in complex landscapes, seascapes, or riverine systems, however, may be shaped by many forces. Recent research has linked habitat heterogeneity and landscape or seascape configuration to genetic structure by integrating methods from landscape ecology, population genetics, and spatial statistics in approaches known as landscape or seascape genetics. However, functional differences...AuthorsChanté D. Davis, Clinton W. Epps, Rebecca Flitcroft, Michael A. BanksKeywordsSourceWiley Interdisciplinary Reviews: Water. 5(2): e1269-.Year2018
