Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae). [PDF]
Am J BotAbstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Changing Rainfall Drives Locally Asynchronous Reproduction of Tropical Birds via Modular Trophic Pathways. [PDF]
Glob Chang BiolIn low‐latitude mountains, we found insectivorous bird communities switched from breeding before to after the dry season at a threshold in dry‐season insects. Localized breeding season reversal of insectivores across wet‐to‐dry gradients magnified short‐term effects of drought and contrasted with the seasonal stability of nectar‐fruit consumers.

Species Limits and Hybridization in Andean Leaf-Eared Mice (<i>Phyllotis</i>). [PDF]
Ecol EvolDiversification of Phyllotis coincided with mid‐ to late‐Pleistocene climate change. Species delimitation revealed cryptic diversity within several nominal forms. Genomic analyses revealed evidence for introgressive hybridization. ABSTRACT Leaf‐eared mice (genus Phyllotis) are among the most widespread and abundant small mammals in the Andean Altiplano,
