Remove saplings early: Cost‐effective strategies to contain tree invasions and prevent their impacts

open access: yesJournal of Applied Ecology, Volume 62, Issue 3, Page 661-676, March 2025.
Our highest‐ranking strategies represent management actions to start implementing in the field as part of an adaptive management plan that iteratively evaluates the validity of our simulation model and updates the management recommendations. Our study can be applied to guide management of invasive pines and replicated with any invasive woody species ...

Modelling alternative management strategies of invasive tree species at the expansion front: Ligustrum lucidum as a case study

open access: yesEcological Solutions and Evidence, Volume 6, Issue 1, January–March 2025.
The management of invasive non‐native species is a global challenge, particularly for long‐lived trees. Individual‐based models (IBMs) and expert knowledge are valuable tools for evaluating different strategies to control the population dynamics and range expansion of invasive species.

Territorial and Non‐Territorial Subpopulations of Wilson's Warblers Return to Central California Breeding Grounds in Two Migratory Waves

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
In this study of Wilson's Warblers, nearly all individuals returning early and becoming territorial were ASY birds, and very few were SY birds. However, second waves of returning Wilson's Warblers, containing both SY and ASY birds, returned about 3–5 weeks after the first migratory waves, and no males in these second waves ever became territorial ...

Feeding en route: Prey availability and traits influence prey selection by an avian predator on migration

open access: yesJournal of Animal Ecology, Volume 93, Issue 9, Page 1176-1191, September 2024.
During fall migration, avivorous raptors and avian prey co‐occur across space and time. We used a novel approach—combining eDNA metabarcoding and eBird data—to investigate predator–prey interactions between an avivorous raptor and co‐occurring avian prey species. This approach revealed prey availability and traits influence raptor‐songbird interactions
