متن کاملThe Effect of Temperature, pH, and Salt on Amylase in Heliodiaptomus viduus (Gurney) (Crustacea: Copepoda: Calanoida)
An interesting α-amylase has been obtained in large quantity (2400 U/g of body weight) with specific activity (20.22 U/g protein) from a freshwater zooplankton, Heliodiaptomus viduus (Gurney). Partially purified enzyme showed activity up to 70 oC and demonstrated optimum activity at 30 oC. The enzyme was active between pH 3.5 and 8.5, with maximum activity at pH 6.0. It retained its full activi...
متن کاملDistribution of some calanoida (Crustacea: Copepoda) from the Yucatán Peninsula, Belize and Guatemala.
Southern Mexico and Central America have many water bodies of different morphology and water chemistry with an interesting zooplankton fauna, originating from North or South America. A set of 63 samples, taken in 2005 and 2008, from water bodies of the Yucatan Peninsula karst, Belize and Guatemala, were studied for the content of calanoid copepods. Old and recent literature was used to determin...
متن کاملA new species of Notodiaptomus from the Amazon basin (Crustacea, Copepoda, Calanoida, Diaptomidae)
A new Diaptomidae species is presented from the Neotropical region. It was found in two Amazonian lakes, Ressaca and Arapujá, both in Pará State, Brazil. The lakes are 400 km apart and threatened by the building of reservoirs for hydropower generation and pollution by human settlements. The new species resembles N. paraensis Dussart & Robertson, 1984, but it can be distinguished from this speci...
متن کاملA new species of Notodiaptomus Kiefer (Crustacea, Copepoda, Calanoida, Diaptomidae) from Brazil.
Description of a new species of Diaptomidae (Crustacea, Copepoda, Calanoida) Notodiaptomus oliveirai is given from the material obtained at a reservoir at Barra Bonita, SP in 1992. The new species is very similar to Notodiaptomus henseni Dahl 1894 although both species can be found in the same locality, constituting two distinct populations. Notodiaptomus oliveirai seems to be endowed with grea...
