Displaying 3,221 - 3,230 of 65,164 Publications- Oystershell scale (OSS; Lepidosaphes ulmi L.) is an invasive insect that threatens sustainability of aspen (Populus tremuloides Michx.) in the southwestern United States. OSS invasions have created challenges for land managers tasked with maintaining healthy aspen ecosystems for the ecological, economic, and aesthetic benefits they provide. Active management is required to suppress OSS populations and mitigate damage to aspen ecosystems, but before management strategies can be implemented, critical knowledge gaps about OSS biology and ecology must be filled. This study sought to fill these...AuthorsConnor D. Crouch, Richard Hofstetter, Amanda Grady, Nylah Edwards, Kristen Waring, Christopher RangerKeywordsSourceEnvironmental EntomologyYear2024
- Reliable population estimates are important for making informed management decisions about wildlife species. Standardized survey protocols have been developed for monitoring population trends of the wood turtle (Glyptemys insculpta), a semi-aquatic freshwater turtle species of conservation concern throughout its distribution in east-central North America. The protocols use repeated active search surveys of defined areas, allowing for estimation of survey-specific detection probability (p) and site-specific abundance. These protocols assume population closure within the survey area during...AuthorsAllyson N. Beard, Donald J. Brown, Eric T. Hileman, Michael T. Jones, Jena M. Staggs, Ron A. Moen, Andrew F.

Fuel types misrepresent forest structure and composition in interior British Columbia: a way forward
Background - A clear understanding of the connectivity, structure, and composition of wildland fuels is essential for effective wildfire management. However, fuel typing and mapping are challenging owing to a broad diversity of fuel conditions and their spatial and temporal heterogeneity. In Canada, fuel types and potential fire behavior are characterized using the Fire Behavior Prediction (FBP) System, which uses an association approach to categorize vegetation into 16 fuel types based on stand structure and composition. In British Columbia (BC), provincial and national FBP System fuel...AuthorsPaul F. Hessburg, Marc-André Parisien, Gregory A. Greene, Sarah E. Gergel, Lori D. Daniels, Jennifer N. BaronKeywordsSourceFire Ecology. 20:15.Year2024- Wildlife must adapt to human presence to survive in the Anthropocene, so it is critical to understand species responses to humans in different contexts. We used camera trapping as a lens to view mammal responses to changes in human activity during the COVID-19 pandemic. Across 163 species sampled in 102 projects around the world, changes in the amount and timing of animal activity varied widely. Under higher human activity, mammals were less active in undeveloped areas but unexpectedly more active in developed areas while exhibiting greater nocturnality. Carnivores were most sensitive,...AuthorsChristopher Beirne, Kaitlyn M. Gaynor, Catherine Sun, A. Cole Burton, Alys Granados, Maximilian L. Allen, Jesse M. Alston, Guilherme C.

- Sturgeons are among the most endangered fishes in the world. Identifying habitat use characteristics to inform restoration projects is crucial for recovery. However, small sample sizes, inadequate replication of studies, and limited spatial extents complicate our ability to effectively apply the findings of single studies to endangered species conservation across the larger riverscape. We synthesized information from amphidromous and anadromous sturgeons in North America to identify species-specific knowledge gaps and conduct a quantitative comparison of species–habitat relationships. We...AuthorsErin K. Gilligan-Lunda, Adam Duarte, James T. PetersonKeywordsSourceCanadian Journal of Fisheries and Aquatic Sciences. 81(5): 508-524.Year2024
- Objective: Managers can modify river flow regimes using fish monitoring data to minimize impacts from water management infrastructure. For example, operation of the gate-controlled Delta Cross Channel (DCC) in California can negatively affect the endangered Sacramento River winter-run Chinook Salmon Oncorhynchus tshawytscha. Although guidelines have been developed for DCC operations by using real-time juvenile fish sampling count data, there is uncertainty about how environmental conditions influence fish occupancy and the extent to which those relationships are affected by sampling and...AuthorsJoseph E.

- Western palearctic salamander susceptibility to the skin disease caused by the amphibian chytrid fungus Batrachochytrium salamandrivorans (Bsal) was recognized in 2014, eliciting concerns for a potential novel wave of amphibian declines following the B. dendrobatidis (Bd) chytridiomycosis global pandemic. Although Bsal had not been detected in North America, initial experimental trials supported the heightened susceptibility of caudate amphibians to Bsal chytridiomycosis, recognizing the critical threat this pathogen poses to the North American salamander biodiversity hotspot. Here, we...AuthorsDeanna H. Olson, Evan H. Campbell Grant, Molly Bletz, Jonah Piovia-Scott, David Lesbarrères, Jacob L. Kerby, Michael J. Adams, Maria Florencia Breitman, Michelle R.

- Riverine landscapes in many ways represent the birthplace of intensive human settlement and development (Gregory, 2006). This long, ubiquitous and continually changing relationship continues to the present day. Considering the infrastructure associated with this high level of development (dams, diversions, roads, railways, farms, commercial and residential structures) is essential in the context of riverine landscape resilience. However, in spite of a heavy human footprint, almost all large river basins comprise a complex mosaic of highly and minimally developed land and water, generally...AuthorsKeith Nislow, Francis J.

- This perspective emerged from ongoing dialogue among ecologists initiated by a virtual workshop in 2021. A transdisciplinary group of researchers and practitioners conclude that urban ecology as a science can better contribute to positive futures by focusing on relationships, rather than prioritizing urban structures. Insights from other relational disciplines, such as political ecology, governance, urban design, and conservation also contribute. Relationality is especially powerful given the need to rapidly adapt to the changing social and biophysical drivers of global urban systems....AuthorsSteward T. A. Pickett, AbdouMaliq T.

- Introduction: Under climate change, drought is increasingly affecting forest ecosystems, with subsequent consequences for ecosystem services. An historically exceptional drought in Texas during 2011 caused substantial tree mortality. We used 2004–2019 Forest Inventory and Analysis (FIA) data and state-wide weather data to examine the climatic conditions associated with this elevated tree mortality. Methods: We measured moisture extremes (wet to dry) using the Standardized Precipitation Evapotranspiration Index (SPEI) at two timescales (12- and 36- month). We quantified heat wave severity...AuthorsShakirudeen Lawal, Jennifer Costanza, Frank H. H. Koch, Robert M. SchellerKeywordsSourceFrontiers in Forests and Global ChangeYear2024
