Family forest owners (FFOs) own a large percentage of forestland in the United States, and actions and behaviors on their forestland have a large impact on wildfire prevention and mitigation across the landscape. Using data from the USDA Forest Service’s 2018 National Woodland Owner Survey, we investigated national and regional FFO wildfire attitudes and behaviors. We see that concern for wildfire is relatively high across the United States; however, this...AuthorsSarah Butler, Brett J. Butler, Emma M. SassSourceForest ScienceYear2024
- Wildfires have emerged as one of the most destructive natural disasters worldwide, causing catastrophic losses. These losses have underscored the urgent need to improve public knowledge and advance existing techniques in wildfire management. Recently, the use of Artificial Intelligence (AI) in wildfires, propelled by the integration of Unmanned Aerial Vehicles (UAVs) and deep learning models, has created an unprecedented momentum to implement and develop more effective wildfire management. Although existing survey papers have explored learning-based approaches in wildfire, drone use in...AuthorsSayed Pedram Haeri Boroujeni, Abolfazl Razi, Sahand Khoshdel, Fatemeh Afghah, Janice L.

- Understanding the genetic basis of how plants defend against pathogens is important to monitor and maintain resilient tree populations. Swiss needle cast (SNC) and Rhabdocline needle cast (RNC) epidemics are responsible for major damage of forest ecosystems in North America. Here we investigate the genetic architecture of tolerance and resistance to needle cast diseases in Douglas-fir (Pseudotsuga menziesii) caused by two fungal pathogens: SNC caused by Nothophaeocryptopus gaeumannii, and RNC caused by Rhabdocline pseudotsugae. We performed case–control genome-wide association analyses and...AuthorsPooja Singh, Brad St. Clair, Brandon M. Lind, Richard Cronn, Nicholas P.

- Forests are recognized for sustaining good water chemistry within landscapes. This study focuses on the water chemistry parameters and their hydrological predictability and seasonality (as a component of predictability) in watersheds of varying scales, with and without human (forest management) activities on them, using Colwell indicators for data collected during 2011-2019. The research was conducted in three forested watersheds located at the US Forest Service Santee Experimental Forest in South Carolina USA. The analysis revealed statistically significant (α = 0.05) differences between...AuthorsAndrzej Wałęga, Devendra M. Amatya, Carl C.

- Objective: In the U.S. Pacific Northwest, climate change is increasing air temperatures, decreasing warm season (April-September) streamflow, and increasing cool season (October-March) streamflow. Warmer water temperatures may alter conditions for migratory coldwater fishes like the Bull Trout Salvelinus confluentus. Consequently, an understanding of Bull Trout migration and survival is critical for species conservation and restoration. In the Salmon River basin, Idaho, 1992 and 1993 transpired to be two of the most opposing extreme years among the past three decades for warm season water...AuthorsPatti J. Wohner, Russ F.

- Snow leopards (Panthera uncia) inhabit the mountainous regions of High Asia, which experienced serial glacial contraction and expansion during climatic cycles of the Pleistocene. The corresponding impacts of glacial vicariance may have alternately promoted or constrained genetic differentiation to shape the distribution of genetic lineages and population structure. We studied snow leopard phylogeography across High Asia by examining range-wide historical and contemporary genetic structure with mitochondrial DNA and microsatellite markers. We genotyped 182 individuals from across snow...AuthorsImogene A. Cancellare, Byron Weckworth, Anthony Caragiulo, Kristine L. Pilgrim, Thomas M.

- Physical and genetic isolation are recognized as significant threats to wildlife, especially in large carnivores inhabiting fragmented landscapes. We conducted an initial genetic assessment of pumas (Puma concolor) using 19 microsatellite loci for the emblematic puma population in the Torres del Paine UNESCO Biosphere Reserve in southernmost Chile, which exhibits some distinctive phenology that some local people speculate may be due to isolation and inbreeding depression. We extracted DNA from 385 scats collected in the field, of which 96 were identified as puma, representing 20 unique...AuthorsL. Mark Elbroch, Byron V Weckworth, Kristine L.

- Predation is a fundamental process that shapes ecological communities. The impact of mountain lion (Puma concolor) predation on their prey, however, is a debated topic among wildlife managers and their primary constituents, hunters and conservationists in North America. Here we present a perspective and highlight recent literature on the direct and indirect (i.e., non-consumptive) effects of mountain lion predation on 2 of its primary prey species in western North America, mule and black-tailed deer (Odocoileus hemionus). We assert that direct effects of mountain lion predation outweigh...AuthorsTavis Forrester, Heiko U. WittmerKeywordsSourceCanadian Wildlife Biology and Management. 13(2): 1-40.Year2024
- Thornton and Murray (2024; hereafter TM) sought to further our understanding of historical and future Canada lynx (Lynx canadensis) habitat in the contiguous USA to guard against shifting baseline syndrome and aid conservation planning for this federally threatened species. We commend the intent of this exercise, however several issues limit the application of TM to lynx conservation, including model design and validation, extensive extrapolation, ambiguous source data, and plausibility of the results.AuthorsJacob S.

- Fire-adapted species have evolved to exploit resources in heterogenous landscapes that presumably maximize energy acquisition and minimize energetic expenditure. However, limited empirical work exists demonstrating the explicit energetic mechanisms that drive such adaptive responses to fire across diverse landscapes.AuthorsKate McGinn, Ceeanna Zulla, Marilyn Wright, Zachary Wilkinson, Brian Dotters, Kevin Roberts, John J.
