The parallelus form of A. villosus is considered the subject of this paper. In Michigan, OTP has a 2-year life cycle, with twigs pruned primarily in even-numbered years and adults emerging from the fallen twigs in odd-numbered years. During 1990 to 2011, I studied various aspects of OTP life history in southern Michigan (Ingham County). Based on measurements from over 300 infested oak twigs, they averaged 43.1 cm long, 9.4 mm in diameter at...AuthorsRobert A. HaackKeywordsSourceThe Great Lakes EntomologistYear2024
- Impervious surfaces caused by urbanization alter hydrologic conditions. In ultra-urban areas (75% or more impervious), rooftop stormwater control measures (SCMs), such as green roofs, exploit underutilized rooftop space. Green roofs reliably attenuate rainwater, but associated water quality treatment results are not as consistent. This study explored the viability of blue roofs, an emerging technology, as an alternative to green roofs. Nine adjacent plots consisting of three each of conventional (control), green, and blue roofs were constructed in Raleigh, NC. As a part of hydrology...AuthorsSarah E.

- Stable isotope data have made pivotal contributions to nearly every discipline of the physical and natural sciences. As the generation and application of stable isotope data continues to grow exponentially, so does the need for a unifying data repository to improve accessibility and promote collaborative engagement. This paper provides an overview of the design, development, and implementation of IsoBank (www.isobank.org), a community-driven initiative to create an open-access repository for stable isotope data implemented online in 2021. A central goal of IsoBank is to provide a web-access...AuthorsOliver N. Shipley, Anna J. Dabrowski, Gabriel J. Bowen, Brian Hayden, Jonathan N.

- A major threat to small mammalian carnivore populations is human-induced land use change, but conservation and management are inhibited by limited knowledge about their ecology and natural history. To fill a key knowledge gap of the western spotted skunk (Spilogale gracilis), we investigated their spatial ecology at the landscape and home range scale in the temperate rainforests of the Oregon Cascades during 2017–2019. For the landscape scale analysis, we used detections of western spotted skunks at 112 baited camera traps and fitted a dynamic occupancy model to investigate spatial...AuthorsMarie I Tosa, Damon B.

- Background. The rising occurrence of simultaneous large wildfires has put strain on United States national fire management capacity leading to increasing reliance on assistance from partner nations abroad. However, limited analysis exists on international resource-sharing patterns and the factors influencing when resources are requested and deployed. Aims. This study examines the drivers of international fire management ground and overhead personnel deployed to the United States. Methods. Using descriptive statistics and case examples data from 2008 to 2020, this study investigates the...AuthorsSunniva Bloem, Alison C. Cullen, John T. Abatzoglou, Linda O. Mearns, Erin J.

- Applying an interaction framework, we examined whether climate change and combined land use and disturbance changes were synergistic, antagonistic, or neutral for forest issues of wildfires, tree growth, tree species distributions, species invasions and outbreaks, and deer herbivory, focused on the eastern United States generally since the 1800s and the development of instrumental records (1895). Climate largely has not warmed during 1981-2020 compared to 1895-1980, but precipitation has increased. Increased precipitation and land use (encompassing fire exclusion and forestation, with...AuthorsBrice Hanberry, Marc D. Abrams, Gregory J. NowackiKeywordsSourceForests. 13: 398.Year2024
- Globally, in remaining wildlands, tree densities and forested cover have increased in grasslands and open forests since European settlement. In the southern Rocky Mountains of Colorado, United States, we determined tree composition and tree cover from historical (years 1875 to 1896) surveys and compared them to current (2002 to 2011) tree composition and current (year 2016) forested land cover for 500,000 ha of the Routt National Forest. Additionally, we examined whether changes in precipitation occurred. Regarding composition, pine (primarily lodgepole pine; Pinus contorta) decreased from...AuthorsBrice Hanberry, Jacob M.

- Current locations of species may not be suited to future climate, resulting in ranges that shift to higher latitudes, with potential for range expansion or contraction in extent. To identify potential shifts in distributions of 119 tree species centered in the United States and Canada, I modeled species occurrences under current climate and then predicted to past (20, 10, and 6 thousand years ago) and future climates (six projections during 2071–2100 for North American warming of 4.3 ◦C to 8.8 ◦C), with a singular focus on the climate space of tree species, or bioclimatic envelope models....AuthorsBrice HanberryKeywordsSourceTrees, Forests and People. 17: 100612.Year2024
- Since Euro-American settlement and associated fire exclusion, grasslands and open forests have converted to forests throughout the United States. Contributing to the weight of evidence, we determined if forestation also occurred in forests and grasslands of Colorado. Our study extent encompassed landscapes of the 0.5 million ha Arapaho and Roosevelt National Forests in the northern Front Range (eastern side) of the southern Rocky Mountains and the 1 million haWeld County, which contains Pawnee National Grassland, in the Great Plains grasslands. We quantified tree composition, cover, and...AuthorsBrice Hanberry, Jacob M. Seidel, Phillip DeLeonKeywordsSourceFire. 7: 103.Year2024
