Genome Sequence and Population Genomic Analysis of Cronartium quercuum f.sp. fusiforme
ABSTRACT Fusiform rust, caused by Cronartium quercuum f. sp. fusiforme (Cqf), is the most severe disease of planted southern pines in the south‐eastern United States. Despite the critical role pathogen genomics play in disease outcomes, the population structure and genetic variability of Cqf remain poorly characterised.

Measuring congruence between available and selected vegetation at wild turkey nest sites
We evaluated whether female wild turkeys (Meleagris gallopavo ssp.) differentially selected vegetation characteristics on the first day of egg laying across 164 nesting attempts and 492 travel paths. Vegetation conditions at nest sites were commonly available along movement paths, and visual obstruction did not influence nest success, suggesting nest ...
