With spatially explicit population trends in-hand, how can we quantitatively explore the potential impacts of #habitatchange? Here’s a transferable method using trends from the eBird Team and Johnston et al. 2025.

How do #HabitatChange 🚜, #Pollution 🏭, #ResourceExploitation 🎣, #ClimateChange 📈 and #InvasiveSpecies🌴 as combined human impacts affect #biodiversity?

Short and worrying message: distinct decrease in richness and shift in composition.

Fig. 2 from the article: Tick infestation rate across the bird phylogeny.

Fig. 4 from the article: Standard regression coefficients obtained from phylogenetic generalized linear mixed Bayesian models. Model 7 includes species with at least one tick-infested bird and species with no infested individuals. The references for the categorical variables included in the models were: natural (habitat type), migratory (migratory status), gregarious (social behavior), searcher (foraging strategy), and understory (foraging stratum). Dots represent the posterior mean, and the lines represent credible intervals of 95%.

NEW PAPER: examining factors influencing tick infestation in wild birds in Colombia. Larger body size, migratory behavior, and natural habitats increase infestation probability, while ground foraging reduces it.
