excited about this one: using longitudinal movement data and dyadic models, we show that orangutan moms adjust their ranging patterns so their kids can play with age-mates independent of kinship, at personal costs. www.biorxiv.org/content/10.6...

Mothers with similarly aged offspring share more space, and their offspring play more.
Posterior effect sizes from social relations models (SRMs) of (a, b) infant-infant play scans (n = 996
infant-dyad-years across 79 mother dyads) and (c) mother-mother home-range overlap (Bhattacharyya coefficient; n
= 282 mother-dyad years across 71 mother dyads). Panel (a) shows the hurdle component (probability of play
occurrence), sign-flipped so positive values indicate higher probability of play occurrence; panel (b) shows the count
component (play frequency). Points and thick and thin lines show posterior medians with 66% and 89% credible
intervals, respectively. (d) Counterfactual home-range overlap for each dyad when offspring are the same age versus
6 years apart. Points show posterior medians across all mother-mother dyads (one horizontal bar per dyad);
background densities show population-level predictions. (e) Offspring age-difference effect on home-range overlap
versus intersection area. (f) Posterior difference between the two effects (BC overlap minus intersection area).

New paper out today in Nat Ecol Evol! On how within- and between-group competition jointly shape ranging in wild capuchins, and how the environment tips the balance. Thread below 🐒

Is bigger always better? For social animals, group size is a dilemma: big groups face more internal competition, yet hold an edge over smaller neighbors. 33 years of data on 12 wild capuchin groups reveals how these forces shape behavior.

Hi all! I am new to Bluesky so I am just posting some of my earlier research.

GPS is relatively new. So how can we study long-term animal movements? Our approach in @Ecology_Letters transforms historic location records (pre-GPS) into valuable data, revealing capuchins' responses to #climate and demographic change. #openaccess...
