Evidence of introgression amid phylogenetic conflict in Brachyotum, a plant radiation from the Tropical Andes. [PDF]

Am J Bot
Abstract Premise The species‐rich flora of Tropical Andes underwent multiple rapid and recent diversifications, yet resolving their evolutionary histories remains challenging despite increasing phylogenomic data. Here, we examined phylogenomic conflict in Brachyotum (Melastomataceae) to identify sources preventing its resolution.

Miniature temperature data loggers increase precision and reduce bias when estimating the daily survival rate for bird nests

Journal of Field Ornithology, Volume 92, Issue 4, Page 492-505, December 2021., 2021
ABSTRACT Demographic studies of many bird species are challenging because their nests are cryptic, resulting in few nests being found. To maximize statistical power, methods are needed that minimize disturbance while yielding as much information per nest as possible. One way to meet these objectives is to use miniature thermal data loggers to precisely
