Abstract Increasingly frequent megafires are dramatically altering landscapes and critical habitats around the world. Across western United States, have become an almost annual occurrence, but implication of these fires for conservation native wildlife remains relatively unknown. Woodland savannas among world's most biodiverse ecosystems provide important food structural resources to a variety wildlife, they threatened by megafires. Despite this, great majority fire impact studies only been conducted in coniferous forests. Understanding resistance resilience assemblages following extreme perturbations can help inform future management interventions that limit biodiversity loss due megafire. We assessed woodland savanna mammal community short‐term impacts megafire using camera trap data collected before, during, after fire. Specifically, we utilized 5‐year set (2016–2020) from Hopland Research Extension Center examine 2018 Mendocino Complex Fire, California's largest recorded wildfire at time, on distributions eight observed species. used multispecies occupancy model quantify effects species' space use, assess species size diet groups, create robust estimates fire's diversity across time.

Following megafire, richness was higher burned areas retained canopy cover relative with low cover. Fire prevents large‐scale is providing refugia vulnerable immediately oak woodlands, likely other mixed‐forest landscapes.

Abstract In the far western United States, bacterial agent of Lyme disease, Borrelia burgdorferi sensu lato, is primarily transmitted to humans by nymphal stage black-legged tick, Ixodes pacificus. Predicting tick abundance would benefit public health but complicated tick’s complex multi-year life cycle and data limitations. To address this, we used readily available climate data, a long-term dataset from northwestern California, time lags based on cycle. Our model showed that warmer early spring temperatures during non-drought conditions year prior predicted higher densities, while hot, dry springs were linked earlier peaks in their abundance. Incorporating human-induced change projections, activity over next century, with potential for an initial doubling questing nymph numbers. This approach provides valuable tool offers insights into changing dynamics disease ecology far-western US.
