Population structure of the copepods Centropages typicus and Temora stylifera in different environmental conditions
The population structure (NI to adults) of the copepods Centropages typicus and Temora stylifera was investigated in parallel at two sites in the eutrophic and oligotrophic waters of the Gulf of Naples (Tyrrhenian Sea) with the aim of identifying the environmental factors that modulate the occurrence of these calanoids that are abundant in the neritic waters of the Mediterranean Sea. Monthly zo...
متن کاملAcrocalanus gracilis (Copepoda: Calanoida) development and production in the Timor Sea
We investigated the juvenile development of the calanoid copepod Acrocalanus gracilis in the Timor Sea. The development was characterized by the calculation of stage-specific duration, median development time, moulting period duration, moult and growth rates. The morphometry of the experimental and wild populations were compared. Food concentrations in the experiment were lower than those in th...

متن کاملSeasonal cycles of egg production of two planktonic copepods, Centropages typicus and Temora stylifera, in the north-western Mediterranean Sea
The reproductive biology of copepods plays a key role in seasonal population oscillations and therefore determines, among other things, annual production (Kiørboe et al., 1988; Fransz et al., 1989; Ianora and Buttino, 1990; Ianora et al., 1992; Halsband and Hirche, 2001). Reproduction is affected by various environmental factors, basically by temperature and food availability (Dagg, 1978; Landr...
متن کاملFeeding of Boeckella gracilipes (Copepoda, Calanoida) on ciliates and phytoflagellates in an ultraoligotrophic Andean lake
In Andean lakes a distinctive assemblage of large mixotrophic ciliates (>80 μm), dominated by the peritrich Ophrydium naumanni Pejler and the heterotrich Stentor araucanus Foissner & Wölfl, has been previously reported (Wölfl, 1995; Modenutti, 1997; Queimaliños et al., 1999; Modenutti et al., 2000). These two species have been found only in large, deep ultra-oligotrophic lakes (area >5 km2, Zma...
