“…We only included studies conducted on laboratory cultures and under optimal conditions, i.e., where the cohort experiment was started immediately upon maturation. For egg-carrying ambush feeders, their data were supplemented by compilations and data from McKinnon and Klumpp (1998), Ambler et al (1999), Temperoni et al (2011), and Zamora-Terol and Saiz (2013). 1).…”

“…Estimates of maximum egg production rates were taken from the compilation of Bunker and Hirst (2004). For egg-carrying ambush feeders, their data were supplemented by compilations and data from McKinnon and Klumpp (1998), Ambler et al (1999), Temperoni et al (2011), andZamora-Terol and. Egg production rates were converted to a common temperature of 158C using a Q 10 value of 1.54 (Bunker and Hirst 2004).…”

The optimal allocation of resources to repair vs. reproduction in an organism may depend on the magnitude and pattern of the external mortality it is experiencing, which, in turn, may depend on its feeding and mate-finding behavior. Thus, the fundamental activities of an organism, i.e., to feed, to survive, and to reproduce, are interrelated through trade-offs. Here, we use small planktonic copepods to examine how adult longevity and ageing patterns in a protected laboratory environment relate to the feeding mode (active searching vs. passive ambush feeding), mate-finding behavior, and spawning mode of the species. We show that average adult longevity varies between species by an order of magnitude and is independent of body size. Ambush feeders that carry their eggs have longer average life spans and experience higher mortality later in life relative to active feeders that broadcast their eggs. Males generally have shorter life spans and experience higher mortality earlier in life than females, and this difference may be accentuated in species where dangerous mate-finding is male biased. We finally show a trade-off between longevity and fecundity, with ambush feeders producing eggs at a rate five to 10 times lower than the active feeders, consistent with predictions from optimal resource allocation theory.

“…Oithona atlantica is also widely distributed and occurs in the temperate and polar oceanic regions of the Atlantic and Pacific Ocean (Cepeda, Blanco‐Bercial, Bucklin, Beron, & Vinas, ; Nishida, ). While the former two species are abundant in temperate to polar waters, O. nana has also been found extensively in tropical and subtropical zones, mostly in coastal regions (Temperoni, Viñas, Diovisalvi, & Negri, ; Williams & Muxagata, ). The small size of Oithona (<1 mm) and its subtle morphological species‐specific traits that can only be observed by microscopy (Nishida, Omori, & Tanaka, ) represent a serious difficulty for studies involving a large number of samples.…”

New insights into global biogeography, population structure and natural selection from the genome of the epipelagic copepod Oithona

In the epipelagic ocean, the genus Oithona is considered as one of the most abundant and widespread copepods and plays an important role in the trophic food web. Despite its ecological importance, little is known about Oithona and cyclopoid copepods genomics. Therefore, we sequenced, assembled and annotated the genome of Oithona nana. The comparative genomic analysis integrating available copepod genomes highlighted the expansions of genes related to stress response, cell differentiation and development, including genes coding Lin12-Notch-repeat (LNR) domain proteins. The Oithona biogeography based on 28S sequences and metagenomic reads from the Tara Oceans expedition showed the presence of O. nana mostly in the Mediterranean Sea (MS) and confirmed the amphitropical distribution of Oithona similis. The population genomics analyses of O. nana in the Northern MS, integrating the Tara Oceans metagenomic data and the O. nana genome, led to the identification of genetic structure between populations from the MS basins. Furthermore, 20 loci were found to be under positive selection including four missense and eight synonymous variants, harbouring soft or hard selective sweep patterns. One of the missense variants was localized in the LNR domain of the coding region of a male-specific gene. The variation in the B-allele frequency with respect to the MS circulation pattern showed the presence of genomic clines between O. nana and another undefined Oithona species possibly imported through Atlantic waters. This study provides new approaches and results in zooplankton population genomics through the integration of metagenomic and oceanographic data.

“…These estimates are also useful for the assessment of copepod population growth or anthropogenic impacts on the environment (Mauchline, 1998), since they are particularly sensitive to these disturbances (Uye, 1994). Most studies of copepod production rates have been conducted in temperate waters (Sun et al, 2011;Temperoni et al, 2011), and few data available for tropical regions (Hopcroft et al, 1998;Magalhães et al, 2011), including the coastal Amazonian ecosystems, in particular with regard to the short-term variation in copepod productivity. The main objectives of the present study are thus to estimate the diel variation (circadian and tidal cycles) in the biomass and productivity of A. lilljeborgii and A. tonsa in the Taperaçu estuary, a mangrove-dominated system on the Brazilian Amazonian coast, and to evaluate the influence of hydrological variables on these parameters.…”
