Effects of Vector Density on Blood Parasite Spread and Health Consequences for Avian Hosts: An Experimental Epidemiology Blueprint

open access: yesIntegrative Zoology, EarlyView.
In an experimental epidemiology setup, groups of pigeons were exposed to different numbers of infective malaria vectors. Vector number explained the speed of transmission, the final prevalence, and changes in host behavior. ABSTRACT Vector density plays a critical role in the transmission dynamics of vector‐borne diseases and thus in their health and ...

Thresholding species distribution models: Simple approaches for land‐use planning in multifunctional landscapes

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Species distribution models (SDMs) are often used to understand changes to species' distributions and their habitats under different land‐use scenarios, enabling decision makers to prioritize areas for management efforts and balance environmental conservation with socio‐economic demands on the landscape.

Does the total consumption model apply to cannabis use?

open access: yesAddiction, EarlyView.
Abstract Aims To test whether the total consumption model and its extension, the theory of collectivity, apply to adolescent cannabis use. We estimated: (1) whether the distribution of cannabis use frequency was stable over time; (2) whether changes in average cannabis use were mirrored across consumption quantiles; and (3) whether higher average use ...

Commerce, coalitions, and global value chains: Coordinated and collective lobbying on trade

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract Global value chains (GVCs) have connected firms in complex networks within and across national borders. However, political economy models often assume away production linkages and thus fail to explain pervasive and diverse trade coalitions cutting across industries and firms. I develop a GVC‐centered framework where production linkages through
