The Interspersian Index as a Technique for Evaluation of Bobwhite Quail Habitat

An index based on the interspersion of vegetative types proved useful in evaluating quail habitat. Application of the technique for related studies indicated that interspersion indices may find wider application for assessing habitat deficiencies, for evaluating land areas for production of a diversity of wildlife species, and for planning

The Ring-necked Pheasant in Nebraska

Ringneck—Its Past and Prospects: A most successful exotic, pheasant numbers are declining Nuptial Rites and Nesting: Spring recoups winter’s losses Summer Broods: While cocks undergo their annual moult, hens enter the brooding period; for eight weeks, hens attend chicks Hunting the Ring-necked Pheasant Season of Testing: Nebraska’s winters test a pheasant’s mettle, but given good cover and an adequate food supply, the ringneck is almost impervious to the elements Methods of Managemen

The Interspersion Index as a Technique for Evaluation of Bobwhite Quail Habitat

Some forty years ago, the concept of habitat interspersion was advanced by Aldo Leopold (1931). Indicating then that we are only on the threshold of an understanding of the ecology of game species, Leopold went on to postulate his law of interspersion which recognized that “game is a phenomenon of edges.” Although the validity of Leopold\u27s premises has been documented both directly and indirectly many times in the past four decades, the complexity and frustration in describing ecological diversity of game range has continued to pose a problem for wildlife managers since 1931

Aquatic Macroinvertebrates of the White River National Wildlife Refuge, Arkansas

The objectives of this study were to survey the diversity of the aquatic macroinvertebrates ofthe White River National Wildlife Refuge (WRNWR) and determine relative abundances and distributional and seasonal patterns. No comprehensive investigation of WRNWR aquatic macroinvertebrates had been conducted previously. Thirty sampling stations were established within WRNWR. Each station was sampled twice, providing 60 totalsamples, for 1.5 man hours witha Turtox Indestructible™ dip net. Three black light trap samples were taken to augment the species list. A total of 15,056 individuials representing 219 taxa was taken by dip net samples during the sampling period October 1989-September 1990. Insects comprised 76% ofthe organisms captured withColeoptera being the dominant group. The most abundant organism for WRNWR was Hydroporus vitlalipennis. Black light samples and literature records each revealed 21 additional taxa bringing the total taxa currently known from WRNWR to 261. Each of the 30 stations was assigned to one of four associations, which were defined by continuity of determined internal and external factors. The Climax-Isolation Association possessed the most stable and complex community structures; isolation by levees and natural boundaries and scarcity of human intervention probably accounted for this. The Congruent Lentic Association embraced communal structures ofgood quality but possessed factors limiting diversity. The Agriculturally Inflicted-White River Tributary Association supported relaItivelysimple aquatic macroinvertebrate communities. Finally, the Restricted Association consisted oftwo stations containingsignificant limiting factors resulting in concomitantly depauperate aquatic macroinvertebrate communities

Inflation-Produced Magnetic Fields in R^n F^2 and I F^2 models

We re-analyze the production of seed magnetic fields during Inflation in (R/m^2)^n F_{\mu \nu}F^{\mu \nu} and I F_{\mu \nu}F^{\mu \nu} models, where n is a positive integer, R the Ricci scalar, m a mass parameter, and I \propto \eta^\alpha a power-law function of the conformal time \eta, with \alpha a positive real number. If m is the electron mass, the produced fields are uninterestingly small for all n. Taking m as a free parameter we find that, for n \geq 2, the produced magnetic fields can be sufficiently strong in order to seed dynamo mechanism and then to explain galactic magnetism. For \alpha \gtrsim 2, there is always a window in the parameters defining Inflation such that the generated magnetic fields are astrophysically interesting. Moreover, if Inflation is (almost) de Sitter and the produced fields almost scale-invariant (\alpha \simeq 4), their intensity can be strong enough to directly explain the presence of microgauss galactic magnetic fields.Comment: 5 pages, 2 figures.
