Bird Communities and Habitat as Ecological Indicators of Forest Condition in Regional Monitoring
Ecological indicators for long-term monitoring programs are needed to detect and assess changing environmental conditions. We developed and tested community-level environmental indicators forExpand
Cryptic Neogene vicariance and Quaternary dispersal of the red‐spotted toad (Bufo punctatus): insights on the evolution of North American warm desert biotas
Evaluation of nucleotide and haplotype diversity and interpretations from NCA reveal that populations on the Colorado Plateau resulted from a recent, likely post‐Pleistocene, range expansion from the Chihuahuan Desert. Expand
Biodiversity management approaches for stream–riparian areas: Perspectives for Pacific Northwest headwater forests, microclimates, and amphibians
Abstract Stream–riparian areas represent a nexus of biodiversity, with disproportionate numbers of species tied to and interacting within this key habitat. New research in Pacific Northwest headwaterExpand
Winterkill, Oxygen Relations, and Energy Metabolism of a Submerged Dormant Amphibian, Rana Muscosa
Tadpoles apparently have two advantages over frogs during winter: ( I) a greater tolerance of low P02, and (2) a reduced consumption of energy and oxygen at low P 02. Expand
Influences of natural acidity and introduced fish on faunal assemblages in California alpine lakes
In an alpine area of the Sierra Nevada of Qlifomia, naturally acidic waters and introduced fishes both strongly affect the distributions of native amphibians, zooplankton, and macroinvertebrates. TheExpand
Mapping moderate-scale land-cover over very large geographic areas within a collaborative framework : A case study of the Southwest Regional Gap Analysis Project (SWReGAP)
Land-cover mapping efforts within the USGS Gap Analysis Program have traditionally been state-centered; each state having the responsibility of implementing a project design for the geographic areaExpand
Isolation of Remaining Populations of the Native Frog, Rana muscosa, by Introduced Fishes in Sequoia and Kings Canyon National Parks, California
: Rana muscosa (mountain yellow-legged frog) was eliminated by introduced fishes early in this century in many of the lakes and streams in Sequoia and Kings Canyon National Parks, California. InExpand
Respiration of Amphibian Eggs
The vast diversity of amphibian reproductive mode ofers further opportunities to investigate the evolution of embryonic respiration within the physical constraints of the jelly capsule and the incubation environment. Expand
Incubation Time and Rate of Embryonic Development in Amphibians: The Influence of Ovum Size, Temperature, and Reproductive Mode
This analysis assesses the influence of two covariates, ovum size and temperature, on the three parameters above for two orders of amphibians, anurans and caudates, and provides a basis for evaluating the influenceof reproductive mode on parameters of embryonic development. Expand
