A 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...
متن کاملA new species of Mongolodiaptomus Kiefer, 1938 from northeast Thailand and a key to the species (Crustacea, Copepoda, Calanoida, Diaptomidae)
This study describes the new species Mongolodiaptomus loeiensissp. n. collected from a temporary pond nearby a cave located in Loei Province, in northeastern Thailand. Mongolodiaptomus loeiensissp. n. is similar to M. calcarus (Shen & Tai, 1965) in the male but can be distinguished from its congeners by the following unique characteristics in the males: (1) the right caudal ramus has 3 ventral ...
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 کاملA new species of Pseudodiaptomus (Crustacea, Copepoda, Calanoida, Pseudodiaptomidae) from the Prasae River Estuary, Gulf of Thailand
A new species of the calanoid copepod genus Pseudodiaptomus was collected from the Prasae River Estuary, Rayong Province, on the eastern coast of the Gulf of Thailand. This species is definitely assigned to the lobus species group sensu Walter (1986a). The female of the new species differs from other congeners in the elongate genital double-somite with a blunt process ventrally and the second u...
