Resumen

Plankton samples collected from Bahía de La Paz, Baja California Sur, Mexico in June 2008 revealed infection of copepods by Blastodinium spp. Of eight copepod genera encountered in the samples, only one (Paracalanus) was parasitized by Blastodinium. Infection prevalence was low, 0.6 % to 2.0 %, with all parasitized individuals being females tentatively identified as Paracalanus parvus. All but one infected host examined during the study was parasitized by Blastodinium crassum, the sole exception being a Paracalanus cf. parvus infected by Blastodinium contortum. A phylogeny constructed using a dataset of ~1.3 Kb sequences of the small subunit ribosomal DNA gene of B. contortum and B. crassum from Bahía de La Paz and 36 other dinoflagellate sequences available in GenBank, including all available for Blastodinium, placed Blastodinium as a monophyletic clade deep within the Dinokaryota. Sequence divergence among B. contortum ex Paracalanus cf. parvus from Bahía de La Paz, B. contortum ex P. parvus from the Mediterranean Sea, B. contortum ex Clausocalanus arcuicornis, B. crassum ex P. cf. parvus from Bahía de La Paz, and B. navicula ex Corycaeus giesbrechti supported separation of the three parasites as distinct species. Prevalecencia y filogenia de dinoflagelados parásitos (género Blastodinium) que infectan copépodos en el Golfo de California Muestras de plancton recolectadas en junio de 2008 en la Bahía de La Paz, México, revelaron la infección de copépodos por Blastodinium spp. De ocho géneros de copépodos encontrados, solo Paracalanus estuvo parasitado por Blastodinium. El porcentaje de prevalecencia de infección fue bajo, de 0.6 % a 2.0 %. Todos los ejemplares parasitados fueron hembras, identificadas tentativamente como Paracalanus parvus. Los hospederos analizados durante este estudio, a excepción de uno, estuvieron parasitados por Blastodinium crassum, siendo la única excepción Paracalanus cf. parvus, el cual fue infectado por Blastodinium contortum. Se construyó la filogenia usando la base de datos de secuencias ~1.3 Kb de pequeñas subunidades de DNA ribosomal de los genes de B. contortum y B. crassum de La Bahía de La Paz, además de otras 36 secuencias disponibles en GenBank, incluyendo todo lo disponible de Blastodinium y colocando a Blastodinium como un grupo dentro de los Dinokaryota. La divergencia de las secuencias entre B. contortum ex Paracalanus cf. parvus de Bahía de La Paz, B. contortum ex P. parvus del Mar Mediterráneo, B. contortum ex Clausocalanus arcuicornis, B. crassum ex P. cf. parvus de Bahía de La Paz, y B. navicula ex Corycaeus giesbrechti respalda la separación de los tres parásitos como especies diferentes.

Resumen

Fecal pellets produced by mesozooplanktonic copepods (Centropages velificatus and Paracalanus parvus) and macrozooplanktonic Euphausiacea (Euphausia sp.) were examined using scanning electron microscopy. Fragments of the protozoan Sticholonche zanclea were found in both copepod and in Euphausia sp. fecal pellets, even when the abundance of the protozoan in the water was low. The results suggest that S. zanclea is an important food resource for different trophic levels, including meso- and macrozooplankton, in Brazilian coastal waters.

Resumen

ABSTRACT In Argentina, as in other countries of Latin America, cholera has occurred in an epidemic pattern. Vibrio cholerae O1 is native to the aquatic environment, and it occurs in both culturable and viable but nonculturable (VNC) forms, the latter during interepidemic periods. This is the first report of the presence of VNC V. cholerae O1 in the estuarine and marine waters of the Río de la Plata and the Argentine shelf of the Atlantic Ocean, respectively. Employing immunofluorescence and PCR methods, we were able to detect reservoirs of V. cholerae O1 carrying the virulence-associated genes ctxA and tcpA. The VNC forms of V. cholerae O1 were identified in samples of water, phytoplankton, and zooplankton; the latter organisms were mainly the copepods Acartia tonsa, Diaptomus sp., Paracalanus crassirostris, and Paracalanus parvus. We found that under favorable conditions, the VNC form of V. cholerae can revert to the pathogenic, transmissible state. We concluded that V. cholerae O1 is a resident of Argentinean waters, as has been shown to be the case in other geographic regions of the world.

Resumen

In order to characterize the zooplankton community at the Vitória Bay estuarine system (Southeastern Brazil), samples were collected in 10 sampling stations during a three-year study (1998-2000), every three months. A total of 64 taxa were identified.Copepoda contributed with the highest species number (49) in the community, especially with Acartia lilljeborgi,Acartia tonsa,Paracalanus parvus,P. quasimodo,Parvocalanus crassirostris,Temora turbinata,Oithona hebes,Oithona oculata and Euterpina acutifrons. Highest abundances occurred in the summer of 2000. Diversity indexes were higher at the estuary mouth. Zooplankton composition was characterized by coastal and estuarine species, their distribution being influenced mainly by the salinity variation in this estuarine system.

Resumen

In situ grazing activity of mesoplanktonic copepods was investigated by the fluorometric method during an algal spring bloom in a zone of oyster farming in Marennes-Oléron Bay. The grazing activity of copepods was overall higher during the night than during the day for three species (Temora longicornis, Paracalanus parvus and Acartia clausi), but peaks also appeared during the day for all of them. Individual ingestion rates and daily rations were higher during neap tide (low suspended particulate matter (SPM) concentrations) than during spring tide (high SPM concentrations). During ebb tide (when SPM concentrations were the lowest) the feeding activity of T. longicornis, P. parvus and A. clausi was significantly negatively correlated with algal concentration. Our work suggests that during the algal spring bloom in the farming area of Marennes-Oléron Bay the pressure exerted by mesoplanktonic copepods on the algal stock was very low, as a consequence of: (i) high algal concentrations in the field (resuspension and high phytoplanktonic production); (ii) low ingestion rates when high algal concentrations were observed. The likely ingestion of non-fluorescent particles by copepods is discussed.

The main impetus of this research is to explore the behavioral interactions of spinning ciliate and Strobilidium sp. with calanoid copepod (Paracalanus parvus). This study employed video-graphic techniques to record and analyze the encounter of Paracalanus parvus and ciliates. The videotaped images captured three main activities including the swimming trajectory of ciliates, the feeding behavior of Paracalanus parvus, and the escape mechanism of ciliates. In this research, the escape reaction of ciliates is referred by their swimming pattern, reactive distance, and jump kinetics. The two species of ciliates demonstrated different escape reactions to copepods. The spinning ciliate swam faster (1.45±0.61 mm s-1) than did Strobilidium sp. (0.87±0.88 mm s-1). Therefore, the former reduced its resting period and increased the NGDR as a way to escape from potential predators as far as possible. By contrast, the Strobilidium sp. is capable of detecting the appearance of copepods from a distance further away. It took an opposite approach to decrease the NGDR of Strobilidium sp.’s swimming trajectory from 0.38±0.22 to 0.19±0.12 to avoid the feeding current created by Paracalanus parvus. These two ciliates also influenced on the swimming trajectories of Paracalanus parvus. Paracalanus parvus would capture particles nearby and differentiate living organisms from non-living organisms, and then eject indigestible particles to the rear. This research identifies key interactions between the two important primary consumers in the marine ecosystem. The behavioral analysis of species-specific interactions enriches the current understanding of the food web and provides critical knowledge to future study.
