To address this seeming paradox, the impact of incubation time on grazing by nauplii of the subtropical copepod Parvocalanus crassirostris on natural prey assemblages was evaluated.
Nutrients, trace elements and macrobenthic assemblages were evaluated using uni- and multivariate analyzes.
A hierarchical scale of landscape configuration and the plant characteristics of eight seagrass beds were measured and the contributions of these variables as predictors of the properties of the fish and decapod assemblages were evaluated using multiple linear regression models.
In particular, the effects and interaction of varying mesozooplankton abundance (sieved, unsieved and enriched) and enrichment with two nutrients (nitrate and dissolved iron) on spring and summer phytoplankton assemblages were evaluated.
Fish assemblages were evaluated by visual census along two rocky locations impacted by a sewage outfall discharging nearshore (S) and by date-mussel (Lithophaga lithophaga) fisheries (F), respectively, and at two control locations (Cs).
Such response was evaluated in terms of assemblage's composition, richness, taxonomic diversity and functional diversity.
The multiplex PCR was evaluated for specificity using DNA samples representing the common intestinal parasites of dogs and cats, such as Toxocara cati, Trichuris vulpis, Dipylidium caninum, Isospora felis, and G. lamblia (Assemblages C, D, and F).
Correlations between the spatial distribution of soft-sediment assemblages and environmental variables were evaluated at a number of control and potentially impacted locations (waste dumps, a sewage outfall and a wharf) at Casey Station, East Antarctica.
