Forest canopy arthropods as sodium, potassium, magnesium and calcium pools in forests

Forest canopy arthropods as sodium, potassium, magnesium and calcium pools in forests. Schowalter, T. D.; Crossley, D. A., Jr. (Dep. Entomol., Univ. Georgia, Athens, GA 30602, USA). For. Ecol. Manage., 7(2), 143-8 (English) 1983. CODEN: FECMDW. ISSN: 0378-1127. DOCUMENT TYPE: Journal CA Section: 12 (Nonmammalian Biochemistry) The concns. of Na, K, Mg, and Ca were measured in forest canopy arthropod functional groups (groups of species using a similar resource in a similar manner) collected from vegetation of clearcut and uncut hardwood forests at Coweeta Hydrol. Lab., North Carolina, during 1977 and 1978. Functional groups differed significantly in concns. 7439-95-4 and 7440-09-7 which are cas registry numbers of chemicals are mentioned. of the 4 elements. Spiders had the highest Na concns., followed in decreasing order by some other predators and then herbivores. Caterpillars and sawfly larvae had the highest K and Mg concns. and high Ca concn. Detritivores had the highest Ca concns. Evidently, nutrients contained in the nominal biomass of canopy arthropods do not contribute significantly to litter nutrient pools. .

Clinical biochemistry in aquaculture - significance and perspectives

Clinical biochemistry in aquaculture - significance and perspectives. Aldrin, J. F.; Messager, J. L.; Baudin, Laurencin F. (Lab. Natl. Pathol. Anim. Aquat., COB, Brest 29273, Fr.). Publ. Cent. Natl. Exploit. Oceans, [Ser.]: Actes Colloq. (Fr.), 14(Indices Biochim. Milieux Mar.), 291-326 (French) 1982. CODEN: PCNCDH. ISSN: 0335-8259. DOCUMENT TYPE: Journal CA Section: 12 (Nonmammalian Biochemistry) At the Fish Pathol. Lab. in Brest, ~10 blood indexes are routinely measured, as well as plasma protein in micro-electrophoresis and liver glycogen measurements. The choice of parameters and their importance are discussed, and normal values for coho salmon, rainbow trout, and Atlantic bass are presented, based on several years' data in Brittany. Using examples, the consequences of various important aquaculture factors are briefly considered, notably: stress in general, modifications of the environment, and infectious and parasitic factors. The perspectives and limitations of the method are discussed.Except for chemicals metioned above, 57-88-5 and 7439-95-4 are also used. .
