Derek M. Schook, Jonathan M. Friedman, Jamie D. Hoover, Steven E. Rice, Richard D. Thaxton, David J. Cooper
2022, Ecohydrology (15)
Riparian trees and their annual growth rings can be used to reconstruct drought histories related to streamflow. Because the death of individual trees reduces competition for survivors, however, tree-ring chronologies based only on surviving trees may underestimate drought impacts. This problem can be addressed by calculating productivity at the stand...

1. Large-scale, long-term biodiversity monitoring is essential to conservation, land management, and identifying threats to biodiversity. However, multispecies surveys are prone to various types of observation error, including false positive/negative detection, and misclassification, where a species is thought to have been encountered but not correctly identified. Previous methods assume an...
Reevaluation of the role of blocked Oropsylla hirsuta prairie dog fleas (Siphonaptera: Ceratophyllidae) in Yersinia pestis (Enterobacterales: Enterobacteriaceae) transmission
Adelaide Miarinjara, David A. Eads, David M. Bland, Marc R. Matchett, Dean E. Biggins, B. Joseph Hinnebusch
2022, Journal of Medical Entomology (59) 1053-1059
Prairie dogs in the western United States experience periodic epizootics of plague, caused by the flea-borne bacterial pathogen Yersinia pestis. An early study indicated that Oropsylla hirsuta (Baker), often the most abundant prairie dog flea vector of plague, seldom transmits Y. pestis by the classic blocked flea mechanism. More recently, an alternative early-phase mode...
