🚨 New paper! 🚨 🐒 White-faced capuchins experience high rates of infanticide. 🐒 Infanticide is costly to female reproduction. 🐒 Do females exhibit the Bruce effect (termination of pregnancy) to reduce these costs? 🐒 Spoiler: Nope! Read more ▶️ www.sciencedirect.com/science/arti...

dx.doi.org/10.1002/ece3... Led by PhD Candidate @silviacarboni.bsky.social, our new paper explores the contributions of surface microbes to the production of odours in the scent glands of wild tamarins. A great collaboration with Dr. Alice Poirier and @fieldprojects.org #sensoryecology

Not all sexual swellings signal fertility. Some signal strategy. In our new Current Biology paper, we show how gelada females “fake it” during male takeovers—and why it works. authors.elsevier.com/a/1m7%7E93QW...

New paper out on the dangers of using patterns across spatial climate gradients to predict what will happen with changing climate. That includes species distribution modeling. Space-for-time substitution can be misleading in sign, not just the magnitude of effects. www.nature.com/articles/s41...

Honored and profoundly thankful to have received funding from the NSF DDRIG to support my research. I’ll be assessing how wild capuchins respond to extreme ecological challenges behaviorally and physiologically, with a focus on identifying adaptive qualities of prolonged adrenocortical responses.

Had a wonderful time at #IPS2025! More to come soon on how hormone profiles in male white-faced capuchins change during alpha male replacements (co-led w/ @meganpetersdorf.bsky.social)

One of our first papers in a series that investigates the potential for olfactory communication in wild capuchins is now out! Stay tuned for the next pieces of the story 🧪 🐒 👃

🚀 New paper led by Dr Becks Spake! We make the case for precision ecology—using big data & predictive tools to tailor conservation actions to local contexts. Can ecology learn from medicine & marketing to boost impact? We think so. Read it here: rdcu.be/eoaR4 #Conservation #Ecology #BigData

there has been a bunch of (many good) papers coming about about integrating Causal Inference and DAGS into research about behavior and ecology (i.e. doi.org/10.1111/brv....) but i thought it might be useful to show some example empirical papers that do so (see growing thread)...

Fascinating latest model of Homo sapiens evolution within Africa. Interesting finding that cultural innovation was accelerated by both population size increases, but also recombination across partially isolated regions (e.g. Morocco and sub-Saharan Africa)

This brings me far more joy than it probably should

Hot off the press 📣: one of the most surprising and unsettling findings of my PhD. A novel social tradition emerged in the tool-using white-faced capuchins of Jicarón island… abducting and carrying the infants of another species. Thread with gifs, videos, and all the bizarre details 👇

Hey wildflower season, nice to see ya again 🧚

Thank you to those who put this together. #WithoutNSF I couldn’t have afforded my masters & may not be pursuing my PhD today. #WithoutNSF the longitudinal research projects I have been a part of for >5yrs wouldn’t exist. #WithoutNSF we lose a future of possibility in the U.S. #SupportNSF #SaveNSF

Most scientists in the USA don't understand how dire things are. As of April 21, to accept an award, your institution must certify that there are no DEI programs (poorly defined) on campus. No lawyer is going to sign this. This is an effective ban on new grants. grants.nih.gov/grants/guide...

Excited to share this new paper on chimpanzee foraging cognition from the Primate Ecology and Molecular Anthropology Lab at UCSC! #PEMALab So proud to have contributed to this awesome project as an undergrad!! #termitefishing www.nature.com/articles/s41...

We asked how behavioral diversity & agonistic behaviors relate to group size in wild capuchins. We analyzed >65,000 behavioral scans collected over 15 yrs on 214 capuchins (8 groups) & controlled for # inds sampled. We found behavioral richness, diversity & agonism was higher in larger groups.

So incredibly grateful to have received an IPS @ips-primatenews.bsky.social Research Grant and an ASP Conservation Small Grant to support my research on capuchin behavioral and physiological flexibility to extreme environmental conditions! 🙏✨ Exciting things to come✨
