The influence of human presence and footprint on animal space use in US national parks | Proceedings of the Royal Society B: Biological Sciences Given the importance of protected areas for biodiversity, the growth of visitation to many areas has raised concerns about the effects of humans on wildlife. In 2020, the COVID-19 pandemic led to temp...

How do large mammals 🦌🐺 respond to human presence 🥾 and infrastructure 🏕️ in protected areas?

With a fantastic team of collaborators across the US, we set out to answer this question—turns out, it's complicated!

Bear trouble in Sierra Madre: After the Eaton fire, home invasions rise sharply A bear linked to a spate of home break-ins in Sierra Madre in June was euthanized amid what city officials say is an uptick in conflict with the hulking animals.

In communities at the foot of the San Gabriel Mountains, bears and people often cross paths. Some say the Eaton fire has worsened the situation, driving bears whose habitat was charred into neighborhoods to seek food and water. @lilaseidman.bsky.social www.latimes.com/environment/...

By removing invasive bullfrogs, scientists help Yosemite's native turtles recover The huge amphibians "will literally just feed on anything that fits into their mouth" — including turtle hatchlings. Clearing thousands of frogs from ponds helped other species stage a comeback.

awesome conservation success story! Great research Sidney!

Three more wolf packs confirmed in California as ranchers call for relief California wildlife officials confirmed three new wolf packs in Northern California, bringing the state total to 10.

There are three new wolf packs roaming Northern California. It's wonderful news for conservationists who want to see the endangered canids thrive. But the revelation also arrives as ranchers are increasingly agitating for measures to control the animals. bit.ly/43DZxt3

I am so happy to share this new paper I co-wrote with colleagues at the USGS. It's a guide to predicting how nonmotorized recreation like hiking, skiing, mountain biking, etc. affects ungulates (hoofed mammals like deer, elk, moose, and pronghorn) to inform NEPA analyses. doi.org/10.3133/sir2...

Citizen science is ecologically accurate - The Wildlife Society Platforms like eBird and iNaturalist showed low evidence of observation bias

Citizen science platforms are a good tool for researchers to use to gather large-scale data on wildlife species. But how accurate are they, and do they have observation bias?

JWM: Nearly all California city coyotes eat rat poison - The Wildlife Society Efforts to control rodents may affect nontarget species—especially in urban areas

Anticoagulant rodenticides are ubiquitous in some areas. Research in California reveals that nontarget carnivores like coyotes are ingesting these types of rat poison, likely from eating dead rodents.

Congrats this is awesome! I've been so excited to read this ever since seeing your talk on it :)

Great piece by @antonsrkn.bsky.social delving into all the nuance surrounding how the L.A. fires might impact wildlife. Happy to have been part of it, check it out!

6/6

I'll end here with our conceptual model showing that a) fires were historically more prevalent yet served as a stabilizing feedback to ecosystems and humans by reducing fuel loads and risk of higher severity wildfires and b) contemporary fires are now destabilizing to forests and people.
