    Notes: Abstract The species richness and seasonal development of planktonic ciliates were studied and compared in two shallow mesotrophic lakes, one covered with dense submerged macrophytes, the other macrophyte poor. Considerable differences in ciliate species composition, dominant taxa, abundance and biomass were observed. Ciliates were much more species rich in the macrophyte-rich lake, while they were more abundant numerically in the macrophyte-poor lake. Altogether, 96 species, included in 53 genera, 14 orders were identified. Among them, 80 species (included in 45 genera, 14 orders) observed from the macrophyte-rich lake, against 49 species (36 genera, 12 orders) were from the macrophyte-poor lake. In the macrophyte-rich lake, the mean abundance and biomass were 13.5 cells ml-1 and 547.10 μg l-1 f.w.; abundance and biomass were higher in spring and winter; naked oligotrichs dominated total ciliate abundance and Peritrichida dominated the biomass. In the macrophyte-poor lake, ciliate mean abundance and biomass were 35.5 cells ml-1 and 953.39 μg l-1 f.w.; abundances peaked in autumn; Scuticociliates dominated the abundance and Tintinnids dominated the biomass. Possible causes for the observed differences are discussed.

    Publication Date: 2001-07-28
    Description: Planning and decision-making can be improved by access to reliable forecasts of ecosystem state, ecosystem services, and natural capital. Availability of new data sets, together with progress in computation and statistics, will increase our ability to forecast ecosystem change. An agenda that would lead toward a capacity to produce, evaluate, and communicate forecasts of critical ecosystem services requires a process that engages scientists and decision-makers. Interdisciplinary linkages are necessary because of the climate and societal controls on ecosystems, the feedbacks involving social change, and the decision-making relevance of forecasts.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Clark, J S -- Carpenter, S R -- Barber, M -- Collins, S -- Dobson, A -- Foley, J A -- Lodge, D M -- Pascual, M -- Pielke, R Jr -- Pizer, W -- Pringle, C -- Reid, W V -- Rose, K A -- Sala, O -- Schlesinger, W H -- Wall, D H -- Wear, D -- New York, N.Y. -- Science. 2001 Jul 27;293(5530):657-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Duke University, Durham, NC 27708 USA. jimclark@duke.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11474103" target="_blank"〉PubMed〈/a〉

    Publication Date: 2000-09-23
    Description: Researchers are hoping that the Millennium Ecosystem Assessment, a new 4-year, $20 million project that will get under way early next year, will synthesize what's known about the world's ecosystems and help policy-makers deal with those that are under siege. The assessment will turn loose ecologists and social scientists to gather and analyze data on the state of the world's ecosystems, assess nature's ability to provide essential "services" such as food and clean water, and project environmental trends such as deforestation, loss of species, and pollution. But some say that the assessment could end up a victim of its own lofty goals--to evaluate ecosystem health, supply data to implement treaties, and sell the message that ecosystems have economic value.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kaiser, J -- New York, N.Y. -- Science. 2000 Sep 8;289(5485):1676-7.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11001730" target="_blank"〉PubMed〈/a〉

    Publication Date: 2001-07-14
    Description: Living organisms encounter various growth conditions in their habitats, raising the question of whether ecological fluctuations could alter biological macromolecules. The advent of complete genome sequences and the characterization of whole metabolic pathways allowed us to search for such ecological imprints. Significant correlations between atomic composition and metabolic function were found in sulfur- and carbon-assimilatory enzymes, which appear depleted in sulfur and carbon, respectively, in both the bacterium Escherichia coli and the eukaryote Saccharomyces cerevisiae. In addition to genetic instructions, genomic data thus also provide paleontological records of environmental nutrient availability and of metabolic costs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baudouin-Cornu, P -- Surdin-Kerjan, Y -- Marliere, P -- Thomas, D -- New York, N.Y. -- Science. 2001 Jul 13;293(5528):297-300.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre de Genetique Moleculaire, Centre National de la Recherche Scientifique, 91 198 Gif-sur-Yvette Cedex, France., Evologic SA, 4 rue Pierre Fontaine, 91000 Evry, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11452124" target="_blank"〉PubMed〈/a〉

    Why we don't get sick: the within-host population dynamics of bacterial infections (2001)

    Details
    Publication Date: 2001-05-16
    Description: To pathogenic microparasites (viruses, bacteria, protozoa, or fungi), we and other mammals (living organisms at large) are little more than soft, thin-walled flasks of culture media. Almost every time we eat, brush our teeth, scrape our skin, have sex, get bitten by insects, and inhale, we are confronted with populations of microbes that are capable of colonizing the mucosa lining our orifices and alimentary tract and proliferating in fluids and cells within us. Nevertheless, we rarely get sick, much less succumb to these infections. The massive numbers of bacteria and other micro- and not-so-micro organisms that abound and replicate in our alimentary tract and cover our skin and the mucosa lining our orifices normally maintain their communities in seemingly peaceful coexistence with the somatic cells that define us. Why don't these microbes invade and proliferate in the culture media within the soft, thin-walled flask that envelops us? Why don't they cause disease and lead to our rapid demise?〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Levin, B R -- Antia, R -- AI40662/AI/NIAID NIH HHS/ -- GM 54268/GM/NIGMS NIH HHS/ -- GM33782/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2001 May 11;292(5519):1112-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Emory University, Atlanta, GA 30322, USA. blevin@emory.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11352067" target="_blank"〉PubMed〈/a〉

    The ecology of genetically diverse infections (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-05-16
    Description: Microparasite infections often consist of genetically distinct clonal lineages. Ecological interactions between these lineages within hosts can influence disease severity, epidemiology, and evolution. Many medical and veterinary interventions have an impact on genetic diversity within infections, but there is little understanding of the long-term consequences of such interventions for public and animal health. Indeed, much of the theory in this area is based on assumptions contradicted by the available data.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Read, A F -- Taylor, L H -- New York, N.Y. -- Science. 2001 May 11;292(5519):1099-102.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Cell, Animal and Population Biology, University of Edinburgh, Edinburgh EH9 3JT, UK. a.read@ed.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11352063" target="_blank"〉PubMed〈/a〉

    High plant diversity in Eocene South America: evidence from Patagonia (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-04-05
    Description: Tropical South America has the highest plant diversity of any region today, but this richness is usually characterized as a geologically recent development (Neogene or Pleistocene). From caldera-lake beds exposed at Laguna del Hunco in Patagonia, Argentina, paleolatitude approximately 47 degrees S, we report 102 leaf species. Radioisotopic and paleomagnetic analyses indicate that the flora was deposited 52 million years ago, the time of the early Eocene climatic optimum, when tropical plant taxa and warm, equable climates reached middle latitudes of both hemispheres. Adjusted for sample size, observed richness exceeds that of any other Eocene leaf flora, supporting an ancient history of high plant diversity in warm areas of South America.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilf, Peter -- Cuneo, N Ruben -- Johnson, Kirk R -- Hicks, Jason F -- Wing, Scott L -- Obradovich, John D -- New York, N.Y. -- Science. 2003 Apr 4;300(5616):122-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geosciences, Pennsylvania State University, University Park, PA 16802, USA. pwilf@geosc.psu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12677065" target="_blank"〉PubMed〈/a〉

    Uses and abuses of mathematics in biology (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-07
    Description: In the physical sciences, mathematical theory and experimental investigation have always marched together. Mathematics has been less intrusive in the life sciences, possibly because they have until recently been largely descriptive, lacking the invariance principles and fundamental natural constants of physics. Increasingly in recent decades, however, mathematics has become pervasive in biology, taking many different forms: statistics in experimental design; pattern seeking in bioinformatics; models in evolution, ecology, and epidemiology; and much else. I offer an opinionated overview of such uses--and abuses.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉May, Robert M -- New York, N.Y. -- Science. 2004 Feb 6;303(5659):790-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Zoology Department, Oxford University, Oxford OX1 3PS, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14764866" target="_blank"〉PubMed〈/a〉

    Description: Research Groups: Department of Zoology University of Nairobi, P.O. Box 30197, Nairobi, Kenya Kenya Marine and Fisheries Research Institute, P.0. Box 81651, Mombasa, Kenya
    Description: The food habits of two schooling planktivorous fishes, Sardinella gibbosa and Atherinomorous lacunosus, were investigated in Mtwapa creek and Wasini Channel of the Kenya coast. Spatial and temporal variations in their food and feeding habits were assessed using the percentage numerical abundance method, percentage frequency of occurrence, stomach fullness indices and the Tokeshi graphical method. This study established a clear spatial separation of Mtwapa creek from Wasini Channel in terms of the abiotic and biotic data. Highly significant differences (t-test, p 〈 0.05) were observed between the two study areas in temperature, salinity, transparency, conductivity, chlorophyll a and in zooplankton abundance and diversity. The diet of the two fish species showed clear spatial and temporal differences, which were dependent on habitat variability. The two species belong to the omnivorous trophic category. Sardinella gibbosa from both sites fed mostly on copepods during the two seasons. Atherinomorous lacunosus fed mostly on phytoplankton, copepods and nematodes during the NE Monsoon. However, its diet was dominated by nematodes during the SE Monsoon. Overall, both fish species exhibited generalised and opportunistic feeding habits. Their diet was influenced by changes in the quality and quantity of food in the environment and the fishes migratory patterns.
