Some new research! We found that redlined neighborhoods in 177 U.S. cities had less greenspace, less naturally shaped greenspace, and lower connectivity among patches of greenspace. This relationship also increased with city population size! 🧪 esajournals.onlinelibrary.wiley.com/doi/10.1002/...

Out today, a companion article for my autoOcc R package: Estimating species occupancy across multiple sampling seasons with autologistic occupancy models via the autoOcc R package. #rstats 🧪 besjournals.onlinelibrary.wiley.com/doi/10.1111/...
Ecologists have limited options when modelling species distributions through time, especially when data are limited. The autoOcc R package provides a solution to this, making it simple to fit autologistic occupancy models, compare them, and make model predictions.

In the past I've told people that "I've seen it all" when it comes to conducting an urban #cameratrapping study for 15 years. But today, after literally millions of images collected, we now have our first image of a deer peeing in the woods, so I guess there is still more to see out there 🤣🤣🤣🧪

Disability in ecology and evolution
In this TrendsTalk series ‘Disability in ecology and evolution’ in Trends in Ecology and Evolution, we hear from people about their experiences being disabled in ecology and evolution. We are asking ecologists and evolutionary biologists with disabilities what the community could do to make our field more inclusive – these changes can be very practical things (e.g., large fonts), they could be institutional, or involve people’s attitudes and beliefs. If you identify as disabled or have a chronic condition, and would like to share your thoughts, please get in touch – tree@cell.com, we would love to hear from you.

An update from the team on the uncertain future of our program and the impact of NSF budget cuts. Please share and reach out 🦠
Some difficult news from the team:

In NSF's FY25-26 Budget Request to Congress, we learned that our program will take a whopping 50% cut - meaning that in September, we'll be $1.25m short of an operating budget that currently supports a cohort of seven PhD students, four postdocs, and three full-time staff.

Verena is one of the largest and last pandemic prevention-focused programs in the United States: since 2020, we've supported the training of over 60 postdocs, graduate students, and undergraduates. Our researchers have established unique laboratory resources for studying animal immune systems, and discovered new antiviral immune adaptations in bats; developed risk assessment algorithms for wildlife and livestock viruses, and diagnostic algorithms for viruses like dengue, Ebola, and Zika; and quantified the effects of climate change, deforestation, and factory farming on spillover risk. Everything we develop is 100% open source, and our data has supported the research of nearly 150 external researchers in 21 countries to date.

We have three months to make up our budget shortfall. Every dollar spent on Verena supports not just our team, but the community of researchers who use our data, code, and resources. You can help us by sharing this post, and reaching out if you're able to support a unique and vulnerable program. Or just head over to viralemergence.org, and take a look at what we do. 🦟 🦇 🦠
