Flocking propensity by satellites, but not core members of mixed-species flocks, increases when individuals experience energetic deficits in a poor-quality foraging habitat by Gentry, Katherine E, Roche, Daniel P, Mugel, Stephen G, Lancaster, Nolan D, Sieving, Kathryn E, Freeberg, Todd M, Lucas, Jeffrey R

“…Mixed-species bird flocks are complex social systems comprising core and satellite members. Flocking species are sensitive to habitat disturbance, but we are…”

Can variation in seed removal patterns of Neotropical pioneer tree species be explained by local ant community composition? by Ruzi, Selina A., Zalamea, Paul‐Camilo, Roche, Daniel P., Achury, Rafael, Dalling, James W., Suarez, Andrew V.

“…Many plants depend on animals for seed dispersal, and ants commonly fill this role. We examined whether heterogeneity in ant community composition among sites,…”

Species identity influences secondary removal of seeds of Neotropical pioneer tree species by Ruzi, Selina A., Roche, Daniel P., Zalamea, Paul-Camilo, Robison, Abigail C., Dalling, James W.

“…Primary dispersal agents move seeds from the maternal plant to the soil surface where they are often moved again by secondary dispersal agents. However, the…”

Individual variation in foraging behavior reveals a trade-off between flexibility and performance of a top predator by Pintor, Lauren M, McGhee, Katie E, Roche, Daniel P, Bell, Alison M

“…There is increasing evidence that behavioral flexibility is associated with the ability to adaptively respond to environmental change. Flexibility can be…”
