Third Report Of The North Dakota Bird Records Committee: 2004-2005, Dan Svingen, Ron E. Martin

The Prairie Naturalist

Since 1979, North Dakota's bird records committee has collected, evaluated, and archived documentations of rare bird occurrences in the state. In 2004 and 2005, this committee resolved 189 rare bird records. On the basis of these record reviews, six species were ad~ed to the North Dakota state bird list: mottled duck (Anas fulvigula), yellow-billed loon (Cavia adamsii), white-tailed kite (Elanus leucurus), little stint (Calidris minuta), glaucous-winged gull (Larus glaucescens), and great black-backed gull (Larus marinus). Four species were added to the list of nesting species within the state: snowy …

Common Raven Nests In North Dakota After 100-Year Hiatus, Melvin P. Nenneman, Todd A. Grant, Ron E. Martin

The Prairie Naturalist

Our observations represent the first documented nesting by the common raven in North Dakota since the late 1800's. Houston (1977) suggested that the expansion of the American crow onto the Canadian prairies was limited by the scarcity of trees for nest sites, which also might have limited the extent of the common raven. Aspen woodland has increased substantially in and around J. Clark Salyer National Wildlife Refuge since European settlement, due primarily to fire suppression and extirpation of large herbivores (Grant and Murphy 2005). Thus, plausibly these increases in woodland habitat might be providing nest sites necessary for the common …

Factors Associated With Duck Use Of Impounded And Natural Wetlands In Western South Dakota, Jane E. Austin, Deborah A. Buhl

The Prairie Naturalist

Many wetlands in the northern Great Plains west of the Missouri River are stock ponds, created by impoundment of natural drainages or excavation of existing wetlands to provide water for livestock or improve habitat for waterfowl. We evaluated factors influencing use of wetlands by breeding duck pairs and broods relative to modification, water regime, size, and hydrological location on United States Forest Service lands within the Grand River National Grassland in northern South Dakota (2003 and 2004). Responses for both indicated pairs and broods were related positively to wet area, total wetland area within 4 km, emergent edge cover, and …

Brood Parasitism In A North American Population Of White-Faced Ibis, Mark E. Clark

The Prairie Naturalist

In 2007 while monitoring reproductive success among various overwater nesting birds at J. Clark Salyer National Wildlife Refuge in North Dakota, I observed parasitism of a white-faced ibis nest by a cattle egret. I located a nest on 23 May 2007 that contained four white-faced ibis eggs and one cattle egret egg. The nest was located in the middle of a small colony of nesting white-faced ibis (approximately 35 pairs) and black-crowned night herons (approximately 30 pairs). On 3 June 2007 all of the eggs were still present in the nest, but two of the white-faced ibis eggs began hatching …

Effect Of Drought And Agriculture On Ring-Necked Pheasant Abundance, Nebraska Panhandle, Charles J. Randel Iii

The Prairie Naturalist

The objectives of my study were to detennine the effects of drought (e.g., Palmer Modified Drought Severity Index; PMDI, Bridges et at. 2001) and/or agricultural practices (e.g., conversion) on RNP abundance in the Nebraska Panhandle (NP).

My RNP survey data were found to be correlated negatively to drought condition (PMDI) in January, February, and April. This was supported by Snyder (1984) and Riley (1995), both of whom reported that decreased precipitation in spring affected RNP production in the western Great Plains and Iowa, respectively. Late winter and early spring drought affect subsoil moisture and decrease primary production (Kiesselbach et al. …

The Prairie Naturalist Manuscript Submission Guidelines, Christopher N. Jacques, Troy W. Grovenburg, Jonathan Jenks

The Prairie Naturalist

These guidelines present The Prairie Naturalist (PNAT) policies and procedures for submitting scientific manuscripts for consideration for publication. In January 2009, a change in Editorial staff occurred and these guidelines address the ongoing transition and update the online "Suggestions for Contributors" guidelines provided on the PNAT website (http://www.fhsu.edu/biology/pn/prairienat.htm); these instructions supersede all previous guidelines. Tables and appendices are included for common word expressions with superfluous wording, examples of correct format and style guidelines for tables accompanying manuscripts, guidance in properly preparing Research Articles and Notes, citing literature, and mandatory abbreviations for tables, figures and parenthetical expressions.

Modeling The Status And Threats To The Philippine Eagle In The Eastern Mindanao Biodiversity Corridor, Vicente Calag, Sean Fitzgerald, James Hafner, Jayson Ibanez, Alicia Johnson, Don Sluter

James A Hafner

The Philippines is among the most endemic-rich areas for all global biodiversity hotspots. Conserving that biodiversity presents multi-scaled challenges including the critical need for habitat and species level documentation as a basis for identifying conservation targets. This paper contributes to that need by describing the use of A Composite Bio-geographic Analysis (CBA) model to model the dynamics and inter-relationships between species distribution, nest, habitat and land use change, population distribution and access to the PA and to synthesize and evaluate data on the status and threats to the Philippine Eagle Pithecophaga jefferyi in the Mt. Hamiguitan Protected Area, one of …

Fundamentals For Using Geographic Information Science To Measure The Effectiveness Of Land Conservation Projects, Robert G. Pontius Jr., Shaily Menon, Joseph Duncan, Shalini Gupta

Shaily Menon

Some humans spend a tremendous amount of effort to change landscapes from a “natural” state to a “developed” state for a variety of desirable economic uses, such as urban, agriculture, transportation, and mining. Others spend a tremendous amount of effort to prevent such development in order to conserve the landscapes for a variety of important environmental uses, such as biodiversity maintenance, carbon storage, water filtration, and landslide prevention. It would be efficient in theory if a society were to focus its development efforts at locations that give the largest economic utility per area developed, and to focus its conservation efforts …
