    Recruitment dynamics in complex life cycles (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-09-16
    Description: Organisms living in the marine rocky intertidal zone compete for space. This, together with predation, physical disruption, and differing species tolerances to physiological stress, explains the structure of the ecological communities at some sites. At other sites the supply of larvae is limiting, and events in the offshore waters, such as wind-driven upwelling, explain the composition of intertidal communities. Whether the community ecology at a site is governed by adult-adult interactions within the site, or by limitations to the supply of larvae reaching the site, is determined by the regional pattern of circulation in the coastal waters. Models combining larval circulation with adult interactions can potentially forecast population fluctuations. These findings illustrate how processes in different ecological habitats are coupled.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roughgarden, J -- Gaines, S -- Possingham, H -- DE-FG03-85ER60362/DE/NIDCR NIH HHS/ -- NCA2-258/CA/NCI NIH HHS/ -- New York, N.Y. -- Science. 1988 Sep 16;241(4872):1460-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, Stanford University, CA 94305, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11538249" target="_blank"〉PubMed〈/a〉

    Contributions of bird studies to biology (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-10-27
    Description: Birds are widely distributed, highly diversified, and exhibit behavior and social organizations equal in complexity to mammals, yet they are generally more conspicuous and approachable in natural environments. These attributes make birds excellent subjects in many areas of biological research. The topics in which studies on birds have figured prominently include the mechanisms of species formation, the regulation of the distribution and abundance of animals, the effects of the environment on behavior and physiology, the biological and evolutionary significance of variations in social organizations, the encoding of information in animal communication, the sensory basis for migration and navigation, the effects of hormones on nerve cells and behavior, the ontogeny of brain and behavior, and the structure and function of the vertebrate brain. The outstanding record of avian research suggests that birds will continue to provide important models for developing and testing new ideas in various fields of biology.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Konishi, M -- Emlen, S T -- Ricklefs, R E -- Wingfield, J C -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):465-72.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology, California Institute of Technology, Pasadena 91125.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2683069" target="_blank"〉PubMed〈/a〉

    Genetic engineering of bacteria from managed and natural habitats (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-06-16
    Description: The genetic modification of bacteria from natural and managed habitats will impact on the management of agricultural and environmental settings. Potential applications include crop production and protection, degradation or sequestration of environmental pollutants, extraction of metals from ores, industrial fermentations, and productions of enzymes, diagnostics, and chemicals. Applications of this technology will ultimately include the release of beneficial agents in the environment. If safely deployed, genetically modified bacteria should be able to provide significant benefits in the management of environmental systems and in the development of new environmental control processes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lindow, S E -- Panopoulos, N J -- McFarland, B L -- New York, N.Y. -- Science. 1989 Jun 16;244(4910):1300-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Pathology, University of California, Berkeley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2660261" target="_blank"〉PubMed〈/a〉

    Taxonomic differences in the scaling of brain on body weight among mammals (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-06-30
    Description: Theories for the evolution of brain weight in mammals suggest that closely related species have diverged largely as a result of selection for differences in body weight, but that differences among more distantly related species have arisen due to greater net directional selection on brain weight. This pattern of changing selection causes brain weight to evolve more slowly than body weight among closely related species, such as those in the same genus, than among more distantly related species, such as those from different families or orders; a phenomenon known as the "taxon-level effect." Thus, brain weight differs more for a given difference in body weight as the species compared are more distantly related. An alternative explanation for the taxon-level effect is proposed. Distantly related species are more likely to inhabit different ecological conditions than are more closely related species. Where the taxon-level effect occurs, brain weight appears to have evolved in response to the demands of these different ecological conditions. As a consequence, brain weight differs more among distantly related species, for any given difference in body weight, than among closely related species. This effect, rather than a progressive pattern of changing selection pressures, may account for the taxon-level effect in mammals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pagel, M D -- Harvey, P H -- New York, N.Y. -- Science. 1989 Jun 30;244(4912):1589-93.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Oxford, United Kingdom.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2740904" target="_blank"〉PubMed〈/a〉

    Predator-induced trophic shift of a free-living ciliate: parasitism of mosquito larvae by their prey (1988)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1988-05-27
    Description: Larvae of the treehole mosquito, Aedes sierrensis, release a waterborne factor that induces morphogenesis of one of their prey, the tetrahymenid ciliate Lambornella clarki. Induced free-living trophonts of L. clarki undergo a synchronous response in which cells divide and transform into parasitic cells (theronts) that encyst on larval predators. Parasitic ciliates penetrate the cuticle, enter the hemocoel, and ultimately kill their predator-host. In nature, this trophic shift can lead to predator extinction and dramatic changes in microbial populations. Facultative parasitism by this polymorphic ciliate may have evolved as an antipredator strategy. The experimentally inducible parasitic response of L. clarki provides a novel model for studying cellular morphogenesis of ciliated protozoa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Washburn, J O -- Gross, M E -- Mercer, D R -- Anderson, J R -- AI20245/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1988 May 27;240(4856):1193-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomological Sciences, University of California, Berkely 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3131877" target="_blank"〉PubMed〈/a〉

    Habitat selection in a clonal plant (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-05-03
    Description: Rhizomatous growth may permit the nonrandom placement of ramets into different environments, but whether clonal plants are able to use this means to exercise adaptive habitat choice is not known. Western ragweed (Ambrosia psilostachya) plants are shown to preferentially colonize nonsaline soil over saline soil patches, and clones with the strongest preference for nonsaline soil are those least able to grow when restricted to saline conditions. In clonal plant species, nonrandom associations of genotypes with specific environments may thus reflect habitat selection by plants as well as selective mortality imposed by different habitat patches.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Salzman, A G -- GN 07197/PHS HHS/ -- New York, N.Y. -- Science. 1985 May 3;228(4699):603-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3983647" target="_blank"〉PubMed〈/a〉
