  1. The use of scuba-based photo/video methods for characterizing coral reef habitats has gained increased popularity within the last decade, but few work examined the potentiality of surface photography to provide accurate, reliable habitat profiles in…
  2. Until now, water quality monitoring has relied heavily on spot sampling followed by instrumental analytical measurements to determine pollutant concentrations. Despite a number of advantages, this procedure has considerable limitations in terms of…
  3. Oxygen isotopes are sensitive tracers of climate change in tropical regions. Abrupt shifts of up to 18 per mil in the oxygen isotope ratio of diatom silica have been found in a 14,000-year record from two alpine lakes on Mt. Kenya. Interpretation of…
  4. Balancing selection preserves variation at the self-incompatibility locus (S-locus) of flowering plants for tens of millions of years, making it possible to detect demographic events that occurred prior to the origin of extant species. In contrast…
  5. Experiments on the National Spherical Torus Experiment M. Ono et al., Nucl. Fusion 40, 557 (2000) found strong bursts of toroidal Alfvén eigenmode (TAE) activity correlated with abrupt drops in the neutron rate. A fairly complete data set offers the…
  6. Approximately 500 nucleotides of 28S rRNA of 31 species of gnathostomes have been sequenced in order to study the phylogeny of the major fish lineages. In maximum parsimony trees, nodes congruent with those of the morphologically based cladogram…
  7. Perchlorate (ClO(4)(-)), the dissociated anion of perchlorate salts such as ammonium, potassium, and sodium perchlorate, has been recently recognized as a persistent and pervasive contaminant of drinking water supplies in a number of metropolitan…
  8. A baited underwater video (BUV) system for the study of reef-associated fish populations on shallow (10-20 m) rocky habitats in the western Mediterranean was assessed at four locations in Spain and two in France. We describe the apparatus and…
  9. Baseline ecological studies of pristine mangroves are important for monitoring, management and conservation of mangrove ecosystems. Diversity, density, biomass and community structure of crab and molluscan macrofauna were studied in a near-pristine…
  10. AVHRR remote sensing data for sea surface temperature during the first successful satellite track of a basking shark, Cetorhinus maximus on 6 July 1982 is analysed using the new composite front map technique. The shark is shown to have been…
  11. Polyploidy is a common phenomenon occurring in a vast number of land plants. Investigations of patterns of inheritance and the origins of plants (i.e., autopolyploidy vs. allopolyploidy) usually involve cytogenetic and molecular studies of…
  12. Evolutionary biologists often wish to explore the impact of a particular historical event (e.g., the origin of a novel morphological trait, an episode of biogeographic dispersal, or the onset of an ecological association) on rates of diversification…
