Nurse rock microclimates significantly buffer exposure to freezing temperature and moderate summer temperature

Joshua L. Conver, Elliott Yarwood, Lucas D. Hetherington, Don E. Swann
2020 Journal of Arid Environments  
We used data loggers at 11 nurse rock sites to record daily daytime summer maximum and winter nighttime minimum temperatures at Saguaro National Park, Arizona, to examine the effectiveness of rocks to  ...  Our results suggest that the protection from freezing temperature offered by rocks in winter is more ecologically beneficial to the saguaro than extreme temperature amelioration during summer in the cold-limited  ...  Future studies could address whether the effectiveness of temperature mitigation is related to the size, orientation, or slope of the rock cavity, whether saguaro distribution occurs randomly or preferentially  ...

Conservation genomic analysis reveals ancient introgression and declining levels of genetic diversity in Madagascar's hibernating dwarf lemurs [article]

Rachel Williams, Marina B Blanco, Jelmer W Poelstra, Kelsie E Hunnicutt, Aaron A Comeault, Anne D Yoder
2019 bioRxiv   pre-print
Using the size distribution of introgressed regions, we estimate that admixture, and subsequent introgression, occurred between species an average of 4.1 Mya.  ...  We show that phylogenetic relationships among the four lineages of Cheirogaleus demonstrate broad-scale concordance across the genome, and yet we detect a number of discordant genomic regions.  ...  ADY gratefully acknowledges support from the John Simon Guggenheim Foundation and the Alexander von Humboldt Foundation during the writing phase of this project.  ...
