Abundance changes under climate change are likely to occur prior to a detectable range shift. Disturbances are expected to directly affect tree species abundance and composition, and could profoundly influence tree species spatial distribution within a geographical region. However, how multiple disturbance regimes will interact with changing climate to alter the spatial distribution of species abundance remains unclear. We simulated such forest demographic processes using a...AuthorsYu Liang, Eric J. Gustafson, Hong S. He, Josep M. Serra‐Diaz, Matthew J. Duveneck, Jonathan R.

- The future health and productivity of tree species in the northern hardwood forest of eastern North America are uncertain considering changes in climate and pollution loading there. To better understand the trajectory of the northern hardwood forest, we studied the growth of three tree species emblematic of it: sugar maple (Acer saccharum Marsh), American beech (Fagus grandifolia Ehrh.), and yellow birch (Betula alleghaniensis Britton), plus a fourth species, red maple (Acer rubrum L.), whose abundance has increased in the region. We also analyzed the link between growth and several...AuthorsRebecca L. Stern, Paul Schaberg, Shelly A. Rayback, Christopher F. Hansen, Paula Murakami, Gary J.

- The pursuit of ungulates as game animals, whether for recreation, cultural tradition, or meat, is a dominant activity on public and private lands in North America and much of the world. Strategic regulation of hunting is key for managing game population abundance, age and sex structure, and distribution, with harvest rates a function of both hunter success and participation. Hunter satisfaction is often linked to success and ultimately with hunter recruitment and retention, a growing concern for wildlife agencies. Yet knowledge is lacking about what hunter characteristics or behaviors are...AuthorsMary M. Rowland, Ryan M. Nielson, Michael Wisdom, Darren A. Clark, Guy T.

- We conducted a range-wide investigation of the dynamics of site-level reproductive rate of northern spotted owls using survey data from 11 study areas across the subspecies geographic range collected during 1993–2018. Our analytical approach accounted for imperfect detection of owl pairs and misclassification of successful reproduction (i.e., at least one young fledged) and contributed further insights into northern spotted owl population ecology and dynamics. Both nondetection and state misclassification were important, especially because factors affecting these sources of error also...AuthorsJeremy T. Rockweit, Julianna M. Jenkins, James E.

- A small imbalance in plant productivity and decomposition accounts for the carbon (C) accumulation capacity of peatlands. As climate changes, the continuity of peatland net C storage relies on rising primary production to offset increasing ecosystem respiration (ER) along with the persistence of older C in waterlogged peat. A lowering in the water table position in peatlands often increases decomposition rates, but concurrent plant community shifts can interactively alter ER and plant productivity responses. The combined effects of water table variation and plant communities on older peat...AuthorsJulia E. M. Stuart, Colin Tucker, Erik Lilleskov, Randy Kolka, Rodney A. Chimner, Katherine A. A.

- The 1980 volcanic eruption of Mount St. Helens had profound impacts on the geology, hydrology, and ecology of its surrounding landscapes. Consequently, the event provided a unique opportunity to study ecological change over time in relation to abiotic factors. To better assess the role localized environmental conditions play in these larger processes, we have monitored micrometeorological conditions across 6 disturbance zones on Mount St. Helens created by the eruption. We deployed 823 environmental sensors at 191 sites from 1997-2022 to measure the temperature and relative humidity of...AuthorsChristian Che‐Castaldo, Charlie CrisafulliKeywordsSourceEcology. 104(3): e3950.Year2023
- The economic and environmental threats posed by non-native forest insects are ever increasing with the continuing globalization of trade and travel; thus, the need for mitigation through effective biosecurity is greater than ever. However, despite decades of research and implementation of preborder, border, and postborder preventative measures, insect invasions continue to occur, with no evidence of saturation, and are even predicted to accelerate. In this article, we review biosecurity measures used to mitigate the arrival, establishment, spread, and impacts of non-native forest insects...AuthorsHelen F. Nahrung, Andrew M.

- Vehicular emissions comprise a main source of air pollutants, especially particulate matter (PM), which contains toxic compounds. Brazil has been restricting vehicular emissions for more than 30 years to minimize the impacts of fleet vehicles, but despite the restrictive legislation, several Brazilian cities still suffer from the effects of atmospheric pollution. The adoption of nature-based solutions (NbS) is being hailed as a sound alternative for improving urban air quality. In this sense, trees are a true reflection of the NbS concept since they can directly decrease PM levels by...AuthorsMauro Ramon, Andreza Portella Ribeiro, Carolina Yume Sawamura Theophilo, Edson Gonçalves Moreira, Plínio Barbosa de Camargo, Carlos Alberto de Bragança Pereira, Erlandson Ferreira Saraiva, Armando dos Reis Tavares, Antonio Guerner Dias, David J.

- Understanding how trees respond to drought is critical to understanding forest sensitivity to global climate change, which can help inform forest policy and management decisions. However, mechanisms governing carbon fixation and water fluxes in response to increased temperatures and water limitation in regions with Mediterranean climates, with wet winters and dry summers, remain only partially understood. We tested the effect of increased vapor pressure deficit (VPD) and decreased rainfall on water and carbon fluxes of Douglas-fir (Pseudotsuga menziesii) trees using the Soil-Plant-Atmospher...AuthorsKarla M.

- The interest in non-formaldehyde adhesives has reinvigorated studies using proteins from plant and animal sources, with an emphasis on plant-based sources, especially the oilseed plants such as soybean. Although animal-based sources have received much less attention, and ovalbumin from egg whites has not been studied at all, it provides a surprising low viscosity and high wet strength as a wood adhesive. Of the animal and plant proteins used in the past, egg protein has been used for centuries as a binder in tempera, for book illumination, and for gilding, but not as a water-resistant wood...AuthorsLinda F.
