Abstract (from Journal for Nature Conservation): As a zoonotic disease with unprecedented global impacts, COVID-19 may influence how people prioritize issues related to wildlife conservation. Using a nationally representative sample of US residents, we investigated: (1) how COVID-19 affected the relative importance of conservation issues among adults with different political ideologies, and (2) how the pandemic affected political polarization of conservation issues during the 2020 general election in the United States. Conservation issues such as endangered species and controlling zoonotic disease ranked low in importance among the 14 policy issues considered, even lower than environmental issues such as climate...

Abstract (from http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0173844): Urban habitats are characterized by impervious surfaces, which increase temperatures and reduce water availability to plants. The effects of these conditions on herbivorous insects are not well understood, but may provide insight into future conditions. Three primary hypotheses have been proposed to explain why multiple herbivorous arthropods are more abundant and damaging in cities, and support has been found for each. First, less complex vegetation may reduce biological control of pests. Second, plant stress can increase plant quality for pests. And third, urban warming can directly increase pest fitness and abundance. These...
Abstract (from Ecology and Society): Coastal ecosystems in the eastern U.S. have been severely altered by human development, and climate change and other stressors are now further degrading the capacity of those ecological and social systems to remain resilient in the face of such disturbances. We sought to identify potential ways in which local conservation interests in the Lowcountry of South Carolina (USA) could participate in a social process of adaptation planning, and how that process might ultimately be broadened to engage a more diverse set of partners. We engaged participants through a combination of informal meetings, workshops, and other collaborative interactions to explore how the conservation community...

Abstract (from Frontiers in Communication): The efficacy of science communication can be influenced by the cultural values and cognitions of target audiences, yet message framing rarely accounts for these cognitive factors. To explore the effects of message framing tailored to specific audiences, we investigated relationships between one form of cultural cognition—political ideology—and perceptions about the zoonotic origins of the COVID-19 pandemic using a nationally representative Qualtrics XM panel (n = 1,554) during August 2020. First, we examined differences in attitudes towards science (in general) and COVID-19 (specifically) based on political ideology. We found that, compared to conservatives and moderates,...

Abstract (from Tourism Management): Substantial climate change impacts threaten the persistence of cultural resources globally. The need exists for conceptualizing decision support tools that focus on quantifying and optimizing the managerial priorities to leverage historic preservation and adaptation actions that enhance the continuity of heritage values and sites. Informed by the Structured Decision Making (SDM) approach, this study advances the singular objective Optimal Preservation (OptiPres) Model, a decision support tool for climate adaptation planning of historic buildings by considering three tourism management objectives: (a) maximize accumulated resource value, (b) maximize cost-efficiency, and (c) minimize...

Urban forests provide well-documented environmental and societal benefits valued at more than four billion dollars per year in the United States. As cities expand onto land once occupied by rural forests, urban trees take on an even more vital role in mitigating global climate change, conserving biodiversity, and protecting human health. Maintaining the health of trees is challenging in cities and in forests under climate change because of tree stress and pests. Unhealthy trees do not provide adequate ecosystem services or conservation value compared to healthy trees. In this work we found that exotic trees can remain healthy and maintain biodiversity of arthropods (e.g. spiders and insects) that is similar to native...
Abstract (from Environmental Entomology) An insect species’ geographic distribution is probably delimited in part by physiological tolerances of environmental temperatures. Gloomy scale (Melanaspis tenebricosa (Comstock)) is a native insect herbivore in eastern U.S. forests. In eastern U.S. cities, where temperatures are warmer than nearby natural areas, M. tenebricosa is a primary pest of red maple (Acer rubrum L.; Sapindales: Sapindaceae) With warming, M. tenebricosa may spread to new cities or become pestilent in forests. To better understand current and future M. tenebricosa distribution boundaries, we examined M. tenebricosa thermal tolerance under laboratory conditions. We selected five hot and five cold experimental...
Abstract (from MDPI ) Sleeper species are innocuous native or naturalized species that exhibit invasive characteristics and become pests in response to environmental change. Climate warming is expected to increase arthropod damage in forests, in part, by transforming innocuous herbivores into severe pests: awakening sleeper species. Urban areas are warmer than natural areas due to the urban heat island effect and so the trees and pests in cities already experience temperatures predicted to occur in 50–100 years. We posit that arthropod species that become pests of urban trees are those that benefit from warming and thus should be monitored as potential sleeper species in forests. We illustrate this with two case...
Abstract (from SpringerLink) Predation by natural enemies is important for regulating herbivore abundance and herbivory. Theory predicts that complex habitats support more natural enemies, which exert top-down control over arthropods and therefore can reduce herbivory. However, it is unclear if theory developed in other more natural systems similarly apply to predation by vertebrate and invertebrate natural enemies across urban habitats of varying complexity. We used plasticine caterpillar models to assess risk of predation by birds and insects, collected leaf-feeding arthropods, and measured herbivory in willow oak trees (Quercus phellos) in two seasons to determine how predation influenced herbivory across urban...
Abstract (from ScienceDirect): Natural resource plans play a critical role in guiding the sustainable management of forest ecosystems. However, little is known about the quality of management plans. In this study, we evaluated and compared the quality of 35 management plans from federal, state, and nongovernment groups managing longleaf pine ecosystems in the Southeast United States. We developed a plan evaluation tool consisted of five components: (1) Problem and Objective Statement, (2) Fact Base, (3) Actions and Implementation, (4) Integration with Other Plans, and (5) Stakeholder Participation, to examine to what extent plans incorporated planning best practices. We tested a hypothetical model for understanding...
Abstract (from USGS): Adapting cultural resources to climate-change effects challenges traditional cultural resource decision making because some adaptation strategies can negatively affect the integrity of cultural resources. Yet, the inevitability of climate-change effects—even given the uncertain timing of those effects—necessitates that managers begin prioritizing resources for climate-change adaptation. Prioritization imposes an additional management challenge: managers must make difficult tradeoffs to achieve desired management outcomes related to maximizing the resource values. This report provides an overview of a pilot effort to integrate vulnerability (exposure and sensitivity), significance, and use potential...
Abstract (from WileyOnline): Stakeholders fundamentally shape the success of wildlife management, yet little is known about how one of the most important stakeholder groups, wildlife agency decision makers, view emerging conservation challenges. Wildlife agency decision makers collectively shape how wildlife conservation unfolds in North America, but their perspectives are generally absent in the literature. Challenges including climate change, conservation funding models, and wildlife disease make understanding how wildlife decision makers view the future of wildlife conservation essential. We interviewed 48 directors and supervisory board members of wildlife agencies in the southeast United States from July 2019...

Urbanization represents an unintentional global experiment that can provide insights into how species will respond and interact under future global change scenarios. Cities produce many conditions that are predicted to occur widely in the future, such as warmer temperatures, higher carbon dioxide (CO2) concentrations and exacerbated droughts. In using cities as surrogates for global change, it is challenging to disentangle climate variables—such as temperature—from co-occurring or confounding urban variables—such as impervious surface—and then to understand the interactive effects of multiple climate variables on both individual species and species interactions. However, such interactions are also difficult to replicate...
Abstract (from Sustainability): Growing evidence suggests that connection to nature may be linked to mental health and well-being. Behavioral changes brought about by the COVID-19 pandemic could negatively affect adolescents’ connection to nature, subsequently impacting health and well-being. We explored the relationship between connection to nature and well-being before and during the pandemic through a nationally representative survey of adolescents across the United States (n = 624) between April and June 2020. Survey items focused on connection to nature, mental well-being, and participation in outdoor activities before and during the pandemic. Paired-sample t-tests revealed declines in connection to nature,...

Abstarct (from Oikos): Urban landscapes are characterized by high proportions of impervious surface resulting in higher temperatures than adjacent natural landscapes. In some cities, like those at cooler latitudes, trees may benefit from warmer urban temperatures, but trees in many cities are beset with problems like drought stress and increased herbivory. What drives patterns of urban tree health across urbanization and latitudinal temperature gradients? In natural systems, latitude–herbivory relationships are well‐studied, and recent temperate studies have shown that herbivory generally increases with decreasing latitudes (warmer temperatures). However, the applicability of this latitude–herbivory theory in already‐warmed...
Abstract (from Landscape Ecology): Context Development and survival vary across a species’ geographic range and are also affected by local conditions like urban warming, which may drive changes in biology that magnify or reduce the risks of hazardous organisms to people. Larvae of the pine processionary moth (Thaumetopoea pityocampa Schiff; PPM) are covered with setae (hair-like structures) that cause allergic reactions in warm-blooded vertebrates upon contact with the skin, eyes, or respiratory tract. Objectives Our objective was to determine whether PPM larva development, phenology, and survival change with urban warming in ways that affect the risks of this organism to people. Methods In Orléans, France, we...

Abstract (from Global Change Biology): Fill et al. (Global Change Biology, 25, 3562–3569, 2019) reported significant increases in dry season length over the past 120 years in the Southeast US, suggesting increased wildfire risk in a region associated with a frequent fire regime. We identified two flaws that call into question the findings and their relevance to regional wildfire risk. First, with the exception of Florida, there is little evidence for a climatologically meaningful ‘dry season’ in the Southeast because most areas experience relatively evenly distributed monthly precipitation. Second, the sampling method used to derive Cumulative Rainfall Anomalies does not appear to actually reflect a bootstrap sample...
