This report summarizes the inventory of mammals of the five park units comprising the Arctic Network (ARCN) of the National Park Service, Alaska Region, between 2000 and 2003. This study was part of a cooperative effort of the Beringian Coevolution Project at the Museum of Southwestern Biology, University of New Mexico, and the ARCN Inventory and Monitoring Program of the National Park Service, Alaska division. We begin documenting the approximately 39 species of mammals that live in ARCN, with a primary focus on small mammals (i.e., shrews, voles, lemmings, weasels, porcupine, squirrels, and hares). This survey resulted in more than 3,000 primary specimens comprising 23 species. Small mammal abundance varied considerably...

This report details the inventory of mammals in Lake Clark National Park and Preserve (LACL) between 7 and 31 July 2003 as part of a cooperative effort of the Beringian Coevolution Project at the Museum of Southwestern Biology, University of New Mexico and the Inventory and Monitoring Program of the National Park Service of Alaska. We begin the process of documenting the approximately 36 species of mammals that occur in the Park, with a primary focus on small mammals (i.e., shrews, voles, lemmings, weasels, porcupine, squirrels, and hares). This survey resulted in 856 primary specimens comprising 17 species. Across all localities sampled, two shrews (Sorex cinereus, S. monticolus) and a murid rodent (Clethrionomys...

This report summarizes the inventory of mammals of three park units in the Southwest Alaska Network (SWAN) of the National Park Service, Alaska Region, in 2003 and 2004. This study was part of a cooperative effort of the Beringian Coevolution Project at the Museum of Southwestern Biology, University of New Mexico and the SWAN Inventory and Monitoring Program of the National Park Service of Alaska. We begin the process of documenting the approximately 38 species of mammals that occur in SWAN, with a primary focus on small mammals (i.e., shrews, voles, lemmings, weasels, porcupine, squirrels, and hares). This survey resulted in over 2000 primary specimens comprising 18 small mammal species. Small mammal captures varied...

Aim We surveyed the genetic variability of deermice (genus Peromyscus) at the north-western edge of their range to test for occupancy in multiple, hypothesized ice-free regions during the late Pleistocene and explore post-glacial dynamics. Location North-western North America. Methods We used sequences from four independent nuclear and mitochondrial loci from 341 specimens of Peromyscus maniculatus, Peromyscus keeni and Peromyscus sp. (Yukon) to assess species limits, population structure, and demographical change as a result of historical climate change, using a Bayesian approach. Species distribution models were built in MaxEnt to explore the niche overlap amongst genetically distinct species. Results Divergence...

This report details the inventory of the mammals at 10 general localities in the Yukon-Charley Rivers National Preserve (YUCH, the Preserve), upper Yukon River region, Alaska, in July and August 2001. We begin the process of documenting the approximately 40 species of mammals that occur in YUCH with a primary focus on small mammals (the shrews, voles, lemmings, mice, weasels, porcupine, squirrels, pika and hare).
