• organic
  • However, the link between the chemical analyses and the biological tests could be improved as as an organic solvent that solubilised virtually all of the contaminants was used during the chemical analysis while the biological tests were performed in an aqueous solution with limited solubility for a number of compounds.

  • The first step in the biological pump is the synthesis of both organic and inorganic carbon compounds by phytoplankton in the uppermost, sunlit layers of the ocean. (wikipedia.org)
  • The vast majority of carbon incorporated in organic and inorganic biological matter is formed at the sea surface and then must sink to the ocean floor. (wikipedia.org)
  • dietary
  • To test how dietary resource availability affects sexual ornamentation, sperm quality and their interrelationship in three-spined sticklebacks ( Gasterosteus aculeatus ), full-sibling groups were raised under three conditions differing in food quantity and/or quality (i.e. carotenoid content): (i) high-quantity/high-quality, (ii) high-quantity/low-quality or (iii) low-quantity/low-quality.

  • organisms
  • Once this carbon is fixed into soft or hard tissue, the organisms either stay in the euphotic zone to be recycled as part of the regenerative nutrient cycle or once they die, continue to the second phase of the biological pump and begin to sink to the ocean floor. (wikipedia.org)
  • The recognition component, often called a bioreceptor, uses biomolecules from organisms or receptors modeled after biological systems to interact with the analyte of interest. (wikipedia.org)
  • soil
  • The risks associated with a soil contaminated by polycyclic aromatic hydrocarbons (PAHs) are generally assessed by measuring individual PAHs in the soil and correlating the obtained amounts to known adverse biological effects of the PAHs. (eugris.info)
  • It can be concluded from the results presented in the included papers that the PAHs in the studied soils from industrial sites were not generally physically trapped in soil material, indicating that the availability of the PAHs was not restricted in this sense. (eugris.info)
  • The availability and bioavailability of contaminants in soil also has to be studied further, and such future studies should focus on the molecular interactions between the contaminants and different compartments of the soil. (eugris.info)
  • Research has shown that ecosystems with a healthy biological soil crust and native plant community will be resistant to B. tectorum invasion. (wikipedia.org)
  • Research
  • ISBER Best Practices For Repositories: Collection, Storage, Retrieval and Distribution of Biological Materials for Research provides repository professionals with standardized guidelines for the management of biobank specimen collections and repositories. (wikipedia.org)
  • interest
  • The nitrogen cycle is of particular interest to ecologists because nitrogen availability can affect the rate of key ecosystem processes, including primary production and decomposition. (wikipedia.org)
  • environmental
  • ISBER is a global organization which creates opportunities for sharing ideas and innovations in biobanking and harmonizes approaches to evolving challenges for biological and environmental repositories. (wikipedia.org)
  • Sharing successful strategies for accomplishing this goal is one of the driving forces for the International Society for Biological and Environmental Repositories (ISBER). (wikipedia.org)
  • water
  • The effectiveness of these treatments is tightly linked to the timing of the water availability at the site. (wikipedia.org)
  • The biological pump, in its simplest form, is the ocean's biologically driven sequestration of carbon from the atmosphere to deep sea water and sediment. (wikipedia.org)
