Issuance of the commemorative postage stamp in Des Moines, however, was more than recognition of a successful conservation program. It was also a tribute to Jay N. "Ding" Darling, who devoted a lifetime to causes of natural resources management. Generations knew Darling as the Pulitzer Prize winning editorial cartoonist of the Des Moines Register and Tribune, and it was his illustration that provided the design for the first Duck Stamp. As a youth in Sioux City, Iowa, in the late 1800s, Darling was drawn to the unspoiled streams, marshes, and prairies where he established his bond with wildlife and gained an intuitive understanding of ecology. By early manhood, Ding had also witnessed the widespread despoliation of the country's natural resources. As he earned national professional recognition and amassed substantial personal wealth, he also became an articulate and influential spokesman for conservation causes. Darling's early activity in Iowa conservation matters brought the recognition that effective natural resource conservation required professionally educated personnel, a scientific foundation, and protection from political interference. In 1932 he proposed a cooperative education and research program jointly supported by the Iowa State College in Ames, the Fish and Game Commission, and himself. His personal pledge, made during the height of the depression, was $3000 yearly for a three-year trial effort. By mid-1932, the Iowa Cooperative Wildlife Research Unit was established at the college and soon gained prominence through the contributions of its first leader, Dr. Paul L. Errington. Because of such successes in Iowa and his widespread readership, Ding became a leader of the American conservation movement. Although a conservative Republican, he was appointed by President Franklin Roosevelt in 1934 to a special presidential committee charged with recommending a program for the restoration of seriously depleted stocks of migratory waterfowl. Roosevelt, then, soon asked the cartoonist to assume the position of Chief of the Biological Survey, the nation's principal wildlife management agency. Ding agreed to a temporary appointment and quickly proved his mettle as an administrator, reshaping the bureau according to his philosophy. The Washington environment also allowed Darling to promote his Cooperative Wildlife Research Unit concept. In 1935, units based on the Iowa model were established at nine additional land-grant colleges with funding provided by the bureau, the colleges, state game management departments, and the newly formed American Wildlife Institute. This partnership prospered, and a Coop­ rative Fishery Research Unit program was added in 1965. Today, there are 98 FROM THE EDITORS fifteen wildlife units, twenty-one fishery units, and nine combined fishery and wildlife units in twenty-nine states. Thousands of graduates from the unit program have provided the backbone of technical expertise and professional leadership in American wildlife management for fifty years. And their research contributions have been prolific. The Iowa programs alone have spawned over 200 M.S. and Ph.D. graduates and approximately 2000 technical and non­ technical publications. Between 1933 and the present time, some 100 reports have appeared in this journal alone. After a productive 20-month tenure with the bureau, Darling resumed his newspaper position and continued his active involvement in state and national conservation affairs. In Iowa, he had a hand in reopening a Civilian Conservation Corps camp at the Iowa Lakeside Laboratory on West Okoboji Lake. Buildings constructed there by the CCC remain as the nucleus of that facility which has contributed to ecological research and education for many years. Later, he played a role in establishing the Iowa State Teachers'

Like many goose populations worldwide, Greater Snow Geese have increased considerably during the late XXth century (annual growth rate of ~10%). The exploding population of snow geese has imposed considerable stress on its breeding habitat, while extensive use of agriculture lands provides an unlimited source of food during winter and migratory stopovers for them. Remedial management during autumn, winter and spring has been undertaken since 1999 to curb the growth of this population. The long-term objectives of this project are to (1) study changes in the demographic parameters of the Greater Snow Goose population, and especially the effects of the recent spring conservation hunt, (2) determine the role of food availability and fox predation in limiting annual production of geese, and (3) monitor the impact of grazing on the vegetation of Bylot Island.

Fraga ABSTRACT: We present an annotated catalogue of the vascular flora of the upper Santa Ana River watershed, in the southern San Bernardino Mountains, in southern California. The catalogue is based on a floristic study, undertaken from 2008 to 2010. Approximately 65 team days were spent in the field and over 5,000 collections were made over the course of the study. The study area is ca. 155 km2 in area (40,000 ac) and ranges in elevation from 1402 m to 3033 m. The study area is botanically diverse with more than 750 taxa documented, including 56 taxa of conservation concern and 81 non-native taxa. Vegetation and habitat types in the area include chaparral, evergreen oak forest and woodland, riparian forest, coniferous forest, montane meadow, and pebble plain habitats.

Burnham Committee Member Dean of Graduate Studies UTAH STATE UNIVERSITY Logan, Utah 2010 ii ABSTRACT Reproductive Ecology of Astragalus filipes, a Great Basin Restoration Legume by Kristal M. Watrous, Master of Science Utah State University, 2010 Major Professor: Dr. James H. Cane Department: Biology Astragalus filipes Torrey ex. A. Gray (Fabaceae) is being studied and propagated for use in rangeland restoration projects throughout the Great Basin. Restoration forbs often require sufficient pollination services for seed production and persistence in restoration sites. Knowledge of a plant’s breeding biology is important in providing pollination for maximal seed set. Reproductive output from four manual pollination treatments (autogamy, geitonogamy, xenogamy, and distant xenogamy) was examined in a common garden. Pod set, seed set, and seed germination were quantified for each of the treatments. Seed set from four wild populations was compared to that of an openly visited common garden array. A. filipes was found to be self-compatible, but to benefit greatly from outcrossing. Less seed germinated from distantly outcrossed treatments than for any other treatment, indicating possible outbreeding depression. Common garden plants set less seed per pod than any wild population, possibly due to a depauperate pollinator guild in the common garden. iii Bees were surveyed at wild A. filipes populations to identify common pollinators.

Abstract Administered by the USDA Forest Service, the Kiowa and Rita Blanca National Grasslands occupy 230,000 acres of public land extending from northeastern New Mexico into the panhandles of Oklahoma and Texas. A mosaic of topographic features including canyons, plateaus, rolling grasslands and outcrops supports a diverse flora. Eight hundred twenty six (826) species of vascular plant species representing 81 plant families are known to occur on or near these public lands. This report includes a history of the area; ethnobotanical information; an introductory overview of the area including its climate, geology, vegetation, habitats, fauna, and ecological history; and a plant survey and information about the rare, poisonous, and exotic species from the area. A vascular plant checklist of 816 vascular plant taxa in the appendix includes scientific and common names, habitat types, and general distribution data for each species. This list is based on extensive plant collections and available herbarium collections. Authors Donald L.

ABSTRACT Behaviours capture the functional response of plants to environmental factors. I explore behaviours for twenty co-occurring grassland species in response to common belowground environmental factors (competition, mycorrhizae, heterogeneous and high nutrients) and their relationship to plant outcomes. First, detailed plant response to neighbours was observed using a specialized apparatus which allowed for visualization of the root system in situ. Species varied in response from strongly aggregating to strongly segregating roots by adjusting overall size and occupation of the soil and/or by altering allocation to roots and the specific placement of roots. In the second study, associations among response to nutrients, mycorrhizae, neighbours, foraging precision, and soil exploration behaviours created behavioural types along two axes: assertiveness and focus.
