Ecosystem management in 4 dimensions
Management of marine resources is supported by extensive use of acoustic data. Ecosystem management requires simultaneous observations of marine organisms and their interactions. The use of quantitative sonar combined with vertical oriented echo sounders is essential: the multi-frequency echosounder data is used to remotely identify acoustic scattering categories and the spatial distribution of...
متن کاملHuman dimensions from Quranic perspective
Ever since the creation of mankind, there have been different and variable viewpoints about the aspects of the human being. Words such as "Body", "Psyche", "Soul" and "Spirit" have usually been employed regarding human by philosophers, religious scholars, physicians, psychiatrists, and psychologists. Hippocrates, Plato, Aristotle, Galen, Rhazes, Avicenna, Engle, and World Health Organization ha...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Stable Isotopes in Ecosystem Studies
The use of stable isotopes to solve biogeochemical problems in ecosystem analysis is increasing rapidly because stable isotope data can contribute both source-sink (tracer) and process information: The elements C, N, S, H, and all have more than one isotope, and isotopic compositions of natural materials can be measured with great precision with a mass spectrometer. Isotopic compositions change...
متن کاملDimensions of ecosystem complexity: Heterogeneity, connectivity, and history
Biocomplexity was introduced to most ecologists through the National Science Foundation’s grant program, and the literature intended to introduce that program. The generalities of that literature contrast with the abstract and mathematical sophistication of literature from physics, systems theory, and indeed even of pioneering ecologists who have translated the concept intoecology.Thissituation...
