Agnathobathynella ecclesi gen. n., sp. n. aus Malawi und die Formenvielfalt der Familie Bathynellidae (Crustacea, Bathynellacea) Naturalis
Schminke, Horst Kurt.
Agnathobathynella ecclesi gen. n., sp. n. is described from interstitial waters of a stream in Malawi (Africa). There are several unique features characterizing the new genus: mandibles without cutting part, paragnaths extremely elongated, teeth and setae of the maxillula and also the maxilla specialized in various ways, 8th male thoracopod without penis, thoracopods 1 to 7 with 3-segmented endopodites and very reduced setation. Probable relationships between the new genus and Nannobathynella as well as the Gallobathynellinae are discussed. The opinion that morphological diversification is relatively poor in the Bathynellidae is re-examined in the light of recent knowledge and is shown to be invalid.

AGRICULTURAL PROFITABILITY IN THE 1980'S AgEcon
Hasbargen, Paul R..
I'll try, in this paper, to provide some information for the "prudent" planner to consider as he plans farming operations for the 1980's. First a look at farm planning prices, then a few observations on ag profitability and possible changes in ag structure during the coming decade.

Agricultural Protection in OECD Countries: Its Cost to Less-Developed Countries AgEcon
Valdes, Alberto; Zietz, Joachim A..
Many less-developed countries (LDCs) are finding it increasingly difficult to obtain the foreign exchange to pay for growing imports of basic food staples as well as the capital goods and raw materials necessary for their growth and modernization. Agricultural performance particularly is affected by a country’s capacity to import fertilizers and other agricultural inputs. Traditionally agriculture for developing countries and is a logical place to turn for increased earnings. The extent to which agricultural exports can be increased affects the patterns of output growth as well as the allocations of resources to crop-specific research and other inputs. In addition, increasing agricultural exports can lead to an increase in the level of income and...

AGRICULTURAL RESEARCH AND THE FUTURE OF AMERICAN AGRICULTURE AgEcon
Ruttan, Vernon W..
In this paper I first review the sources that have accounted for growth of agricultural production in the past. I then examine the more recent evidence on the contribution of research to growth in agricultural production. Finally, I present some of my own perspectives on issues related to the support for agricultural research and the focus of agricultural research effort over the next several decades.

Agricultural Trade Implications of European Community Enlargement: North America Common Market AgEcon
Membership in the European Community (EC) for Greece, Spain, and Portugal may reduce trade between the United States and the EC in selected commodities; prospects for a North American Common Market are not bright; and the diversion of agricultural crops from export to fuel alcohol production would very likely increase, rather than reduce, balance-of-payment deficits for the United States and Brazil. The first meeting of the Consortium on Trade Research, established by the Economics and Statistics Service's International Economics Division and several universities, focused on and continues to analyze these and other global topics.

Air-lift pumps and the effect of mixing on algal growth OMA
Persoone, G.; Morales, J.; Verlet, H.; De Pauw, N..
Since turbulence is an important factor for the growth of microscopic algae, the effect of mixing intensity and mixing time, has been assessed by means of air-lift pumps as an alternative technology for the agitation of algal cultures. Batch culture experiments in enriched sea water were carried out indoors with <i>Chlorella</i> in 100 liter tanks and outdoors with natural phytoplankton populations in 70 m³ tanks. The respective culturing depths in these tanks were 25 and 180 cm. The role of the mixing was also evaluated against that of the pH regulation of the cultures. Mixing with air-lift pumps increased the algal growth rate significantly in comparison to non-agitated cultures. The yields were also much higher (up to 30%) in mixed than in...

Algumas considerações ecológicas sobre morcegos vampiros na epidemiologia da raiva humana na Bacia Amazônica () Acta Amazonica
Mok,W. Y.; Lacey,L. A..
Resumo Foi realizado um estudo sobre morcegos em locais urbanos e periurbanos em Manaus, Tefé, Benjamin Constant, Belém e Macapá, a fim de avaliar o possível papel dos vampiros na infecção da raiva humana. Não foi possível incriminar os vampiros como tendo algum papel significativo nas áreas estudadas. As características ecológicas dos locais de coletas dos morcegos vampiros foram examinadas e suas implicações na epidemiologia da raiva humana, discutidas.
