Survival and Growth of Larval Coastal Giant Salamanders (Dicamptodon tenebrosus) in Streams in the Oregon Coast Range

Jina P. Sagar, Deanna H. Olson, Richard A. Schmitz

Conditions that affect amphibian larval growth and survival can affect population structure through both larval and adult stages of their life history. We conducted a two-year, mark-recapture study of larval, Coastal Giant Salamanders, Dicamptodon tenebrosus, in 14 small streams in the Oregon …

Associations of the Van Dyke's Salamander (Plethodon vandykei) with Geomorphic Conditions in Headwall Seeps of the Cascade Range, Washington State

Aimee P. McIntyre, Richard A. Schmitz, Charles M. Crisafulli

We explored the association between Van Dyke's Salamander (Plethodon vandykei) and hydrologic condition, geomorphology, and vegetation structure in headwall seeps in the Cascade Range of Washington State. After conducting salamander surveys and measuring habitat characteristics at 40 seep sites from July to …

INFLUENCE OF FIRE AND JUNIPER ENCROACHMENT ON BIRDS IN HIGH-ELEVATION SAGEBRUSH STEPPE

Anna Noson, Richard A. Schmitz, Richard F. Miller

We examined relationships between high-elevation sagebrush (Artemisia spp.) steppe habitats altered by prescribed fire and western juniper (Juniperus occidentalis) encroachment on breeding distributions of Brewer's Sparrows (Spizella breweri), Vesper Sparrows (Pooecetes gramineus), Green-tailed Towhees (Pipilo chlorurus), and Sage Thrashers (Oreoscoptes montanus) on …

Linking Landscape Characteristics to Mineral Site Use by Band-Tailed Pigeons in Western Oregon: Coarse-Filter Conservation with Fine-Filter Tuning

Cory T. Overton, Richard A. Schmitz, Michael L. Casazza

Mineral sites are scarce resources of high ion concentration used heavily by the Pacific Coast subpopulation of band-tailed pigeons. Over 20% of all known mineral sites used by band-tailed pigeons in western Oregon, including all hot springs, have been abandoned. Prior investigations …

Post-precipitation bias in band-tailed pigeon surveys conducted at mineral sites

Cory T. Overton, Richard A. Schmitz, Michael L. Casazza

Many animal surveys to estimate populations or index trends include protocol prohibiting counts during rain but fail to address effects of rainfall preceding the count. Prior research on Pacific Coast band-tailed pigeons (Patagioenas fasciata monilis) documented declines in use of mineral sites …

A Reflected Light-receiver With 2nA Sensitivity Using CDS And A Separate Lowpass-filtering Of The Input Signal At Each Clock-phase

Dirk Killat, Richard A. Schmitz

The design of an integrated receiver for reflected light using correlated double sampling (CDS) is presented. Correlated double sampling has the disadvantage that input signals of high frequencies are folded back to the base band caused by sampling the continuous input signal …

Site Selection and Nest Success of Ring-Necked Pheasants as a Function of Location in Iowa Landscapes

William R. Clark, Richard A. Schmitz, Todd R. Bogenschutz

Wildlife managers in the midwestern United States implicitly recognize that large-scale changes in land use have been a major factor in the nesting ecology of the ring-necked pheasant (Phasianus colchicus), but they have lacked models that quantify the relation between nest success …
