A FEASIBILITY STUDY FOR ESTIMATING THE VALUE OF COMMERCIAL FISHERY AgEcon
Ghanbari, M. Reza.
The "best" use of natural resources -- using them where they are needed the most and can provide the greatest return to society with respect to economic, political, and environmental standards -- is a basic question facing our society. It is a question that has received more and more attention in recent years, as an acute awareness of ecological problems has developed in the industrialized portion of the world. The problem has also become more complex as more and more natural resources are subjected to more intensive multiple uses. Conflicts arise between the users of such resources when the actions of one user encroach upon the use of the resource by another. Usually such conflicts can only be resolved by limiting one or more uses. In the case of...

A Harbour Porpoise, Phocoena phocoena (Linnaeus, 1758), from the Mackenzie River delta, Northwest Territories, Canada (Notes on Cetacea, Delphinoidea VIII) Naturalis
Bree, P.J.H. van; Sergeant, D.E.; Hoek, W..
A Harbour Porpoise, Phocoena phocoena, taken from near Shallow Bay, Mackenzie River Delta, Northwest Territories (68°48’ N 136°35’ W) in July 1973 represents a range extension 800 km eastwards from the previous extreme northeastern record on the north Alaskan coast. All 12 Harbour Porpoises so far examined from either the extreme north of the range of the species in the eastern North Pacific Ocean, or from the extreme south of the range in the eastern North Pacific and eastern North Atlantic Oceans, are large animals.

A key to the species of Mortierella Naturalis
Gams, W..
A key is provided covering only those species of Mortierella of which living cultures are available and which are recognized as specifically distinct. Two subgenera, Micromucor subgen. nov. and Mortierella, and nine sections in the latter are distinguished. The recognized species are listed with some new synonymies and bibliographic documentation. Three species which were invalidly published by Linnemann in 1936 are validated.

A LINEAR PROGRAMMING ANALYSIS OF THE EMPLOYMENT, INCOME AND PRODUCTIVITY OF THE SMALL FARM AND RICE PROCESSING SECTORS OF SIERRA LEONE AgEcon
Rose, Frank S..
Agriculture is the largest sector in the economy of Sierra Leone, employing approximately 75 percent of the population in 1972 and accounting for over 30 percent of the gross domestic product. But though the national economy has grown at an estimated 4.3 percent rate in the last decade, the agricultural sector is estimated to have grown only 1.6 percent per year. The government of Sierra Leone, recognizing the importance of the agricultural sector and the need to develop policies to encourage its growth, has set a goal of increasing the growth rate of the sector to 4.6 percent per annum. Central to the overall agricultural development plan is the emphasis on increased rice production. Rice is the staple food in Sierra Leone, grown by over 80 percent...

A monograph of the fern genus Bolbitis (Lomariopsidaceae) Naturalis
Hennipman, E..
The present study deals with systematic and taxonomic problems in the acrostichoid fern genus Bolbitis (Lomariopsidaceae). The idea came from Prof. Holttum, Kew, in view of his intended revision of the lomariopsidoid ferns for Flora Malesiana. Originally the study was confined to the Asian representatives. However, various problems remained unsolved after the study of these taxa alone, and it was decided to monograph the genus. The taxonomy of the genus Bolbitis was seriously misunderstood in the past—parallel evolution obscuring true relationships—and a rather intricate synonymy has resulted. A brief historical sketch of its taxonomic adventures is worked out. The gross-morphological criteria used for the discrimination of the species by Copeland (who...

A Namurian brachiopod fauna from Meré (Province of Oviedo, Spain) Naturalis
Martínez Chacón, M.L.; Winkler Prins, C.F..
An interesting brachiopod fauna from Namurian (Marsdenian?) deposits — provisionally named the Meré beds herein — is described. The fauna contains seven new species: Drahanorhynchus cantabricus, Anopliopsis? parva, Caenanoplia martinezi, Tornquistia scutiformis, Aseptella asturica, Kitakamithyris merensis, and Plicotorynifer lamellosus; and one new genus: Aseptella with the type species A. asturica. The material of a new productellid and a new ambocoeliid was too poor to give them formal names. The special character of this fauna — only a much older fauna from the Chappel Limestone of Texas (U.S.A.) being closely comparable — indicates special environmental conditions: presumably a soft, muddy bottom. The brachiopod fauna indicates a Namurian, probably...

A new and primitive retrobursal planarian from Australian fresh waters (Platyhelminthes, Turbellaria, Tricladida) Naturalis
Ball, Ian R..
A primitive freshwater planarian, Eviella hynesae gen. et sp. nov. is described from Australia. It is characterized by its lack of eyes and pigment, possession of caudally branched oviducts, and fully fused testes. Although a primary bursa is absent, its function being taken over by the modified female genital canal, the female copulatory system is posterior to the male system. Despite this maricolan feature, and other similarities with primitive southern hemisphere freshwater planarians that have been classified in the Maricola, the present species is placed in the family Dugesiidae of the Paludicola. Evidence from its sensory organs suggests that it belongs on the main evolutionary line from which the majority of Australasian freshwater planarians have...
