- This resource update is a brief look at some of the basic metrics that describe the status of and changes to forest resources in Iowa. This information is based on field data collected using the USDA Forest Service Forest Inventory and Analysis (FIA) annualized sample design, and it is updated yearly.Tables for Forests of Iowa, 2021 can be found at https://doi.org/10.2737/FS-RU-363-TablesThe FIA one-click application that generated this report can be found at https://doi.org/10.2737/FIA-One-Click-State-Report-v1.2.AuthorsUSDA Forest Service.SourceResource Update FS–363.

- Estimates of burn severity and forest change following wildfire are used to determine changes in forest cover, fuels, carbon stocks, soils, wildlife habitat, and to evaluate fuel and fire management strategies and effectiveness. However, current remote-sensing models for assessing burn severity and forest change in the U.S. are generally based on data collected from California, USA, forests and may not be suitable in other forested ecoregions. To address this problem, we collected field data from 21 wildfires in the American Southwest and developed region-specific models for assessing...AuthorsAlicia L.

- Aim: Lepidoptera is a highly diverse, predominantly herbivorous insect order, with species transported to outside their native range largely facilitated by the global trade of plants and plant-based goods. Analogous to island disharmony, we examine invasion disharmony, where species filtering during invasions increases systematic compositional differences between native and non-native species assemblages, and test whether some families are more successful at establishing in non-native regions than others. Location: Hawaii, North America, Galapagos, Europe, South Africa, South Korea, Japan,...AuthorsRichard Mally, Rebecca M. Turner, Rachael E. Blake, Gyda Fenn‐Moltu, Cleo Bertelsmeier, Eckehard G.

- Forest landscapes pattern and development are affected by environment and disturbance. Disentangling their effects is important to understanding current landscape and predicting future changes. Such studies are limited by short-term observation and sparse disturbance-history data. Spatially-explicit forest landscape modeling represents a solution to these limitations. Here, we reconstructed the 300-year-time-series (1710–2010) of postvolcanic- eruption forest landscapes experiencing periodic-typhoons in Changbai Mountain, China, using LANDIS forest landscape model. We used a factorial...AuthorsMia M. Wu, Hong S. He, Yu Liang, Michael Stambaugh, Jacob S. FraserKeywordsSourceEnvironmental Modelling & SoftwareYear2022
- Emerald ash borer (EAB) (Agrilus planipennis), non-native shrubs, and white-tailed deer (Odocoileus virginianus) have been independently shown to affect woody seedling communities. Our objective was to determine the relative importance as well as additive and interactive-effects of these stressors in the context of two environmental factors, canopy tree competition and site wetness. We sampled 24 sites, representing three natural noncongruent gradients in ash mortality, deer browse, and introduced shrub invasion. We explored the responses of seedling species abundance, diversity and...AuthorsBrian M. Hoven, Kathleen Knight, Valerie E. Peters, David L. GorchovKeywordsSourceForest Ecology and ManagementYear2022
- North American ratsnakes (Pantherophis spp.) are regionally important predators whose behavior has previously been linked to habitat fragmentation and climate change. Ratsnakes are hypothesized to benefit from fragmentation that creates favorable microclimates, but previous studies have produced inconsistent results, potentially reflecting geographic variation or study design limitations. We used radiotelemetry and kernel-based home range estimators to evaluate the seasonal movements and habitat use of 53 Western Ratsnakes (Pantherophis obsoletus) in central Missouri, USA. Snakes frequently...AuthorsAndrew D. George, Frank R. Thompson, John FaaborgKeywordsSourceHerpetological Conservation and Biology. 17(2): 306–315.Year2022
- Overwintering success is an important determinant of arthropod populations that must be considered as climate change continues to influence the spatiotemporal population dynamics of agricultural pests. Using a long-term monitoring database and biologically relevant overwintering zones, we modeled the annual and seasonal population dynamics of a common pest, Helicoverpa zea (Boddie), based on three overwintering suitability zones throughout North America using four decades of soil temperatures: the southern range (able to persist through winter), transitional zone (uncertain overwintering...AuthorsDouglas Lawton, Anders S.

- Nitrogen (N) enrichment from excessive fertilization in managed forests affects biogeochemical cycles on multiple scales, but our knowledge of how N availability shifts multi-nutrient stoichiometries (including macronutrients: N, phosphorus, potassium, calcium, magnesium and micronutrients: manganese, iron and zinc) within and among organs (root, stem and leaf) remains limited. To understand the difference among organs in terms of multi-nutrient stoichiometric homeostasis responding to N fertilization, a six-level N supply experiment was conducted through a hydroponic system to examine...AuthorsHongtao Xie, Xueqin Li, Yu Tang, Lauren S.

- Introduction: The COVID-19 pandemic focused attention on city parks as important public resources. However, monitoring park use over time poses practical challenges. Thus, pandemic-related trends are unknown. Methods: We analyzed monthly mobility data from a large panel of smartphone devices, to assess park visits from January 2018 to November 2020 in the 50 largest U.S. cities. Results: In our sample of 11,890 city parks, visits declined by 36.0 % (95 % CI [27.3, 43.6], p < 0.001) from March through November 2020, compared to prior levels and trends. When we segmented the COVID-19 period...AuthorsJonathan Jay, Felicia Heykoop, Linda Hwang, Alexa Courtepatte, Jorrit de Jong, Michelle KondoKeywordsSourceLandscape and Urban PlanningYear2022
- In this study, we compare electricity consumption of the suburban households with similar socio-economic, demographic, and geographic profiles to assess possible roles of social-psychological and behavioral factors. We examine the extent to which these factors influence self-reported energy curtailment (EC) and energy efficiency (EE) behaviors. We also analyze their distinct yet combined roles—often lumped together in the literature— in explaining the total household's electricity consumption. Our study uses a mix of survey responses and monthly utility data from 155 households in a...AuthorsPranay Kumar, Holly Caggiano, Cara Cuite, Clinton J. Andrews, Frank A.
