Wildlife trade drives animal-to-human pathogen transmission over 40 years
New in @science.org โผ๏ธ In the most comprehensive study to date, we show that wildlife trade is driving animal-to-human zoonotic spillover at a planetary scale, with +1 spillover per host every 10 years. Live animal markets and illegal trade pose even greater risks. ๐ www.science.org/doi/10.1126/...
The Willamette Pass in Oregon, at about 5100ft, is usually under about 10 feet of snow this time of year. Today, it is virtually snow free with a temperature of 61ยฐF.
Want to ID whales and dolphins yourself with AnyDorsal? You can access the algorithm yourself via our Python package, Pyseter, philpatton.github.io/pyseter/gett..., or via Happywhale!
New paper alert! Alexandra Vanderzee found that AnyDorsal can effectively identify Risso's dolphins. This is a fun result because a) AnyDorsal wasn't trained on Risso's and b) it shows AnyDorsal can balance scars dorsal notches as separate ID information

For decades biologists assumed ravens follow wolves to their kills.
Our paper @science.org shows something different: ravens rarely follow wolves far. Instead they remember areas where wolf kills are common and return to themโsometimes from >150 km away.

Please check out my recently published demo on fitting singe-season, single-species occupancy models with PyMC.
Ecologists will like PyMC's automatic marginalization feature (adios discrete latent states!) and variety of fast No-U-Turn Samplers (eg, nutpie).

Shoutout to my incredible lab mate, Martin! Such a rad paper!
Thank you to all of my wonderful co-authors, who are too numerous to shout out individually!
False negatives, i.e., an individual was resighted but erroneously marked as a first capture, dictated the optimal strategy in many cases. A 2% increase in the false negative rate translated to a 5% increase in the relative bias in abundance estimates. This rate is easy to compute in practice.
We fed the results into a custom optimization tool to discern the optimal strategy, that is, the optimal method for generating capture histories with an algorithm, for each dataset. We found that true automation was optimal when the algorithm matched images well.
Automating photo-ID creates tradeoffs between reducing effort and increasing estimation error. We explored these tradeoffs with a simulation study, informed by 39 photo-ID datasets representing 24 cetacean species.
Iโm thrilled to see my dissertationโs second chapter published in Conservation Biology. In the paper, we found that researchers can use high-performance identification algorithms to reduce the cost of population assessments without biasing abundance estimates. tinyurl.com/ne8tbpw3

Iโd love to be added if thereโs space!
Exactly. Most procedures like this create more waste than they would have prevented.
Hi everyone! I'm a PhD candidate studying new tools for assessing stocks of whales and dolphins. Here is the first chapter of my dissertation, where we explore the strengths and weaknesses of a multispecies individual identification algorithm. besjournals.onlinelibrary.wiley.com/doi/full/10....
