'Farmers' dependence on agro-companies for agricultural inputs has been growing in east and southern Africa and beyond. At the same time, local and indigenous knowledge about seed selection, saving and multiplying has been lost.
This manual for development workers outlines traditional and current methods of saving seed. It begins with some basic ground rules for working with communities. The second section gives a comprehensive guide to different ways of propagating plants and saving seed from a full range of common crops and trees. Finally, the third part offers a brief outline of the background history and the current issues and …
Morphological Variation Of Allocreadium Lobatum (Digenea: Allocreadiidae) In The Creek Chub, Semotilus Atromaculatus (Osteichthyes: Cyprinidae), In Nebraska, Usa, Monte S. Willis
Transactions of the Nebraska Academy of Sciences and Affiliated Societies
Allocreadium lobatum Wallin 1909, a parasite of fresh-water fish, was originally described as having distinct lobate testes, and subsequent descriptions have left this original description unchanged. The present study quantifies the observation of distinctly non-lobate testes that could be categorized as round or asymmetrical in addition to the previously described lobate testes. Six hundred thirty-six A. lobatum were collected from 228 Semotilus atromaculatus over a 9 month period. Overall, 21.3%, 61.6%, and 16% were found to be round, asymmetrical, and lobate testes respectively (N = 1,071). Analysis of testis morphology found the increasing presence of lobate testis as …

A Synopsis Of The Ferns And Fern Allies Of Nebraska, With Maps Of Their Distribution, Steven B. Rolfsmeier, Robert B. Kaul, David M. Sutherland
School of Biological Sciences: Faculty Publications
An annotated list and county-by-county distribution maps are presented for the 32 species of ferns and fern allies native to Nebraska, based upon field and herbarium studies and critical evaluation of the literature. Native to the state are Isoetes melanopoda, Selaginella rupestris, five species of Equisetum, and 25 species in 18 genera of ferns. Three native species are here verified for the first time, based upon recent collections: Matteuccia struthiopteris var. pensylvanica, Ophioglossum engelmannii, and Pellaeaglabella ssp. glabella. Isoetes melanopoda was rediscovered in 2000, the first record since 1941. Rejected are published reports …

Genetic Evidence For Two Species Of Elephant In Africa, Alfred L. Roca, Nicholas Georgiadis, Jill Pecon-Slattery, Stephen J. O'Brien
Biology Faculty Articles
Elephants from the tropical forests of Africa are morphologically distinct from savannah or bush elephants. Dart-biopsy samples from 195 free-ranging African elephants in 21 populations were examined for DNA sequence variation in four nuclear genes (1732 base pairs). Phylogenetic distinctions between African forest elephant and savannah elephant populations corresponded to 58% of the difference in the same genes between elephant genera Loxodonta (African) and Elephas (Asian). Large genetic distance, multiple genetically fixed nucleotide site differences, morphological and habitat distinctions, and extremely limited hybridization of gene flow between forest and savannah elephants support the recognition and conservation management of two African …
Endangered And Threatened Wildlife And Plants: Establishment Of A Nonessential Experimental Population Of Whooping Cranes In The Eastern United States

Extinction is a natural process. Today, however, plant and animal species are disappearing world-wide at an accelerated pace. Based on current trends, half of the species on earth will be extinct within the next 100 years. The major cause of this phenomenon is large-scale destruction of native habitats, which has increased since European settlement began in the mid 1800's - in Oregon and throughout the New World.
Once lost, a species can never be recovered, and there is no way of knowing how useful it may have been. We do know that human beings and many of their industries depend …

Managing Minnesota's Recovered Wolves, L. David Mech
United States Geological Survey, Northern Prairie Wildlife Research Center: Publications
The Minnesota wolf (Canis lupus) population was estimated by the Minnesota Department of Natural Resources at 2,450 during winter 1997-1998 and had increased at an average annual rate of 4.5°% since winter 1988-1989. The population may be removed from the federal endangered species list by 2002, and management would then return to the state. A federal recovery team recommended a population goal of 1,250-1,400 wolves for Minnesota, with none in the agricultural region. A plan approved by the Minnesota legislature, however, continues the protection of wolves, except for pet and livestock depredation control, for at least 5 years …

Natural Fertility In Whooping Cranes And Mississippi Sandhill Cranes At Patuxent Wildlife Research Center, Jane M. Nicolich, George F. Gee, David H. Ellis, Scott G. Hereford
Proceedings of the North American Crane Workshop
The first fertile whooping crane (Grus americana; WC) egg produced through natural breeding at Patuxent Wildlife Research Center (patuxent) was laid in 1991. Prior to that time, all fertile whooping crane eggs were the result of artificial insemination. Since 1991, eight different whooping crane pairs at Patuxent have produced fertile eggs through natural breeding. Mean fertility averages over years for each pair range from 40% to 93%. Fertility rates for each pair also vary greatly between years, from 0% to 100%, but the causes of the variance are unknown. Experiences with natural fertility in Mississippi sandhill cranes (G …

Counting Cranes: How Much Effort Is Enough?, Douglas H. Johnson, Roderick C. Drewien, Douglas S. Benning
Proceedings of the North American Crane Workshop
Accurate population estimates of sandhill cranes (Grus canadensis) are important because management decisions, such as establishing hunting regulations, are based on those estimates. Counts often are made during aerial surveys when the cranes are congregated. A complete census may be feasible if the area to be surveyed is small and adequate resources are available. For large areas, resources may be inadequate for a census so partial counts (sample surveys) are made. Because cranes are gregarious, the counts in a sample of units may contain either a disproportionately large, or a disproportionately small, fraction of the total, leading to …

Nocturnal Roost Site Selection And Diurnal Habitat Use By Sandhill Cranes During Spring In Central Nebraska, Craig A. Davis
Proceedings of the North American Crane Workshop
During spring 1998 and 1999, the Platte River Whooping Crane Maintenance Trust conducted ground and aerial surveys of staging sandhill cranes (Grus canadensis; hereafter, cranes) to detennine roost site selection and habitat-use patterns along a l20-Ian stretch of the Platte River in south-central Nebraska. Cranes peaked at 232,023 during 22-28 March 1998 and 206,074 during 28 Februaty-6 March 1999 in the study area, a portion of the total crane staging area in the Platte River Valley. Diurnal observations showed that 48% of the cranes were in com fields, 34% in lowland grasslands, 13% in alfalfa fields, and 5% …
