40 AR/39 AR ages for the alkaline volcanism and the basement of Gorringe Bank, North atlantic Ocean ArchiMer
Feraud, Gilbert; Gastaud, Janine; Auzende, Jean-marie; Olivet, Jean-louis; Cornen, Guy.
Gorringe Bank is situated on the Europe-Africa plate boundary at the eastern end of the Azores-Gibraltar fracture zone. It has two summits. Gettysburg Bank to the southwest and Ormonde Bank to the northeast. We applied the 40Ar/39AR stepwise heating method to date six samples of the alkaline volcanic rocks. Two gabbros from the Ormonde Bank and a dolerite from the Gettysburg Bank. The results suggest that the alkaline volcanism lasted probably for less than 6 Ma(66-60 Ma). Although the nature of this volcanism precludes any subduction feature during its setting. the alkaline volcanism of Ormonde is probably linked to Upper Cretaceous/Eocene compressive tectonic events. The basement rocks of Gorringe Bank reveal disturbed 40Ar/39Ar age spectra. One...

A Biosystematic Study of Neohattoria herzogii (Hatt.) Kamim Naturalis
Inoue, Hiroshi; Asakawa, Yoshinori; Gradstein, S. Rob.
Neohattoria Kamim. is a monotypic genus of the Jubulaceae (= Frullaniaceae) with a single species, N. herzogii (Hatt.) Kamim., known from central to northern Japan and the southern part of the Kurile Islands. The present genus was segregated from Frullania by Kamimura (1961; sub. nom. Hattoria Kamim. nom. illeg., non Schust., 1961) on the basis of the branching type, the shape of the first leaf and underleaf on branch, the total lack of secondary pigmentation, the uniform cell structure of the stem in cross section, and the strongly toothed leaf lobes. The generic concept of Neohattoria was greatly expanded by Schuster (1970), who included eight species and classified them into two subgenera, subgen. Neohattoria (with a single species) and subgen....

A Biosystematic Study of Nipponolejeunea Hatt. (Hepaticae) Naturalis
Inoue, Hiroshi; Asakawa, Yoshinori; Gradstein, S. Rob.
The genus Nipponolejeunea Hattori was established by Hattori (1944) based on Pycnolejemea pilifera Steph. from Japan. Its primary important generic characters include 1) the two gynoecial innovations, 2) the triplicate perianth, and 3) the long cilia on leaf- and underleaf-margin. Hattori (1944) also assigned Pycnolejeunea subalpina Horik. to Nipponolejeunea, thus admitting two Japanese species in that genus. Since then, the genus Nipponolejeunea has been repeatedly discussed, especially by Mizutani (1961) and Schuster (1963) from taxonomic points of view. The branching and innovation types of Nipponolejeunea were described by Mizutani (1970); Inoue (1976) proposed the subgeneric separation of the two species, as subgen. Nipponolejeunea (with N. pilifera)...

A Checklist of the Curaçao Sponges (Porifera Demospongiae) including a pictorial key to the more common reef-forms Naturalis
Soest, R.W.M. van.
Although sponges are by no means unimportant organisms, in biomass and diversity, of the Curaçao coral reefs, very few scientific studies have been undertaken in this area involving sponges. To date, apart from taxonomie studies by Arndt (1927) and myself (Van Soest, 1978, 1980), only the boring sponges received attention (e.g. studies of De Groot, in progress). The main reason for this, no doubt, is the confused taxonomy of West Indian sponges. While taxonomie studies are in full progress (but are necessarily slow), it is now already possible to present sufficient data to allow certain identification of the more common reef forms by non-taxonomists for ecological or other purposes. It is one of the objects of the present paper to provide these data; they...

A COMPARATIVE ANALYSIS OF COSTS AND RETURNS TO CATTLE VERSUS SMALL RUMINANT PRODUCTION IN GAO REGION OF MALI AgEcon
Toure, Mariam.
The Gao region located in the northeastern part of Mali was the largest producer of both large and small ruminants in the country before the drought of 1972-1974. Since then, particular trends have been observed in livestock production: (a) small ruminant herds almost reached their pre-drought level in 1976, whereas cattle herds were at 23 percent of their pre-drought level; (b) in 1976-1977, local consumption of small ruminants attained their highest level of the 1970's, whereas cattle consumption decreased at least by a factor of four; and (c) exports of sheep and goats have increased after the drought, while cattle exports are almost nil. These trends suggest that herders have shifted from cattle to sheep and goat production at least during the...

A comparison of coral reef survey methods Naturalis
Weinberg, Steven.
Seven coral reef survey methods were compared in an experimental plot of 100 m² on a Caribbean shelf reef off southwest Puerto Rico. This area was mapped in detail by means of underwater photography and in situ drawings, in order to provide an objective standard against which to test the results obtained by the different survey methods. Minimal survey area was determined, and minimal sampling time deduced for one of the most laborious methods. Two 45-minute periods (i.e. 1.6 X minimal time) were chosen arbitrarily as the standard time alotted to each method. Three survey criteria were chosen: number of species observed, relative coverage (in %) and population densities (in colonies m²). The results of the latter two methods were compared to real values (as...

A COMPARISON OF PROCEDURES FOR ESTIMATING RETURNS TO RESEARCH USING PRODUCTION FUNCTIONS AgEcon
Davis, Jeffrey S..
The production function approach has been one of the two main ex-post procedures used to estimate the rate of return to agricultural research. A critical part of estimating the marginal internal rate of return (MIRR) is the procedure adopted to spread the benefits of research through time. Past studies using this approach have given only brief consideration to this computational procedure. The objective in this study was to review the different computational procedures used and, then, using cross-section production function estimates for U.S. agriculture, determine whether the MIRR estimates are sensitive to the computational procedure used. The results from this comparison indicate a large range in the estimates. The implication, then, is that careful...
