During summer, on the other hand, temperatures are high and phytoplankton abundance low, resulting in low copepod egg production rates (EPR). Despite the apparently better food conditions for copepod growth during winter, we lack information on copepod EPR during the cold season and on the possible effect temperature has on inhibiting this metabolic rate. To solve this uncertainty, a study was carried out to assess the effects exerted by the winter environmental conditions on the EPR of 3 representative planktonic copepod species of the NW Mediterranean (Centropages typicus, Clausocalanus lividus, Acartia clausi). The data were collected during 2 oceanographic cruises in March 1999 (Hivern-99) and January-February 2000 (Hivern-00) and the results compared to those of typical summer conditions. During the Hivern-99 cruise the phytoplankton abundance was very high (ranging from 1 to 1.5 μg > 5 μm chlorophyll a [chl a] l-1), indicating bloom conditions. During the Hivern-00, the phytoplankton bloom had not yet developed, evident by the chl a concentration of ∼0.5 μg l-1. The recorded EPR during Hivern-99 were amongst the highest for the studied species, and the clearance rates deduced from them indicate a shorter (phytoplankton - copepods) food web during the winter phytoplankton bloom than for the rest of the year, when the planktonic trophic interactions take place through a longer microbial food web Peer Reviewed 2019-05-07T08:09:05Z 2019-05-07T08:09:05Z 2002-07 2019-05-07T08:09:05Z artículo http://purl.org/coar/resource_type/c_6501 doi: 10.3354/meps237173 issn: 0171-8630 e-issn: 1616-1599 Marine Ecology Progress Series 237: 173-184 (2002) http://hdl.handle.net/10261/180990 10.3354/meps237173 Publisher's version https://doi.org/10.3354/meps237173 Sí open Inter Research |
