An attempt has been made to experimentally interbreed Atlantic
and Pacific populations of the marine calanoid copepod Acartia clausi
Giesbrecht. Breeding between individuals from each population produced many successive generations in the laboratory, but interbreeding between populations failed to produce viable offspring. This result
is strong evidence that the Atlantic...
Known as the fourth industrial revolution, digitization is an ongoing trend in all fields, in which various industries are integrating information technologies to support and improve their businesses. Nuclear technology industries have also increased their interest in data-driven methods by leveraging the potential of pattern recognition to identify anomalies and...
Over the past decade the International Commission on Radiological Protection has developed a comprehensive approach to environmental protection that includes the use of Reference Animals and Plants (RAPs) to assess radiological impacts on the environment. For the purposes of calculating radiation dose, the RAPs are approximated as simple shapes that...
An attempt has been made to interbreed populations of Acartia clausi from Woods Hole, Massachusetts, and Yaquina Bay, Oregon. Individuals from these populations are morphologically similar, but differ somewhat in size. Cultures from both sources produced many successive generations in the laboratory, but interbreeding with production of viable offspring did...
Background: Pervasive introductions of non-native taxa are behind processes of homogenization of various types affecting the global flora and fauna. Chile's freshwater ecosystems encompass a diverse and highly endemic fish fauna that might be sensitive to the introduction of non-native species, an ongoing process that started two centuries ago, but...
The overall objective of this study is to propose a framework or model for
comprehensive management model of coastal development in Quintana Roo (Quintana
Roo's Coastal Management Program-QRCMP), using a regional approach.
The primary objective of this study is to assess the Mexican experience in
managing coastal natural areas. The assessment is based on the categories, uses,
objectives, and political elements of Mexican protected coastal areas and governmental
efforts to develop and manage these areas. Specific problems within each protected
coastal area...
This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
During the Colonial Period, in Mexico there was no rational
forest development policy and, as a result, forest resources were
squandered and to a considerable extent destroyed. During the
Nineteenth Century, a rational forest policy began to be promoted, but
in the end, it was translated into a policy of...
This compilation lists in chronological order the oceanographic reports published in 1972, 1973 and 1974. It is an update of our reference 74-1 which brought together a listing all the numbered series issued, 1955-1973. It also lists theses for which degrees were awarded in 1974. A theses listing for 1962-1973...
