Abstract: The relationship of physicochemical paramaters of the water and the composition, diversity and abundance of zooplankton assemblage in the nearshore waters surrounding Iligan City were investigated. Hydrological parameters assessed in the waters revealed values that are within the standard set by the Philippines Department of Natural Resources for marine fauna and flora to thrive and be abundant. Rich composition of mesozooplankton was observed with a total of 103 zooplankton comprising the community. Among these zooplankton, copepods were the most numerous group with Canthocalanus pauper, Paracalanus parvus, Oncaea venusta, Acartia erythraea and Oncaea media being the most dominant species in all sampling stations. In terms of copepod diversity profile, relatively high Shannon index (H’: 3.1-3.5) were noted implying that the area is teeming with diverse species of copepods. Although copepods were the most common zooplankton in the area, other groups, namely the protochordates, chaetognaths and chordates (fish eggs and fish larvae) were also abundant. Results of the Canonical Correspondence Analysis (CCA) revealed that water motion may be responsible to the high abundance and diversity of the copepods since this factor can lead to the mixing and transport of more copepods into the area. Hence, the high abundance of these certain groups of zooplankton may imply the high potential of the areas to be used as nursery ground for fish and other macroinvertebrates thereby further supporting the importance of maintaining the marine sanctuary already established in the area.

TL;DR: Small-scale, short-term ex- periments and larger-scale comparative analyses may be inadequate for assessing the strength of trophic interactions, and the potential for community-level responses, not well assessed except at the ecosystem scale, may alternatively dampen or enhance the impacts of Trophic cascades in food webs.

Abstract: Food webs in three lake basins were manipulated by altering fish commu- nities to either reduce or increase the abundance of Daphnia. These basins were subsequently fertilized with nitrogen and phosphorus for two years. We tested three predictions about the response of heterotrophic flagellates, ciliates, and rotifers (collectively, microzooplank- ton) derived from prior studies. We predicted that (1) microzooplankton would increase with lake fertilization, (2) lakes with abundant Daphnia would have lower increases in microzooplankton, and (3) both increases in resource availability and suppression by Daph- nia would determine microzooplankton dynamics. Contrary to the first prediction, micro- zooplankton did not increase with fertilization relative to the reference lake, except in the low-Daphnia system. The second prediction was supported, as Daphnia prevented micro- zooplankton from increasing in the fertilized lakes with the strength of the Daphnia effect being greater than anticipated. Because of this strong effect, microzooplankton dynamics were in all but one case most strongly related to suppression by Daphnia rather than to a combined effect of resources and suppression. The microzooplankton communities were differentially affected by the trophic cascade. Heterotrophic flagellates appeared to be limited by a variety of predators. Even in the low-Daphnia fertilized lake, mortality was apparently high. Ciliates and rotifers increased in the low-Daphnia fertilized lake and were strongly suppressed otherwise. These experiments indicate that small-scale, short-term ex- periments and larger-scale comparative analyses may be inadequate for assessing the strength of trophic interactions. The potential for community-level responses, not well assessed except at the ecosystem scale, may alternatively dampen or enhance the impacts of trophic cascades in food webs.

TL;DR: The extension of classical trophic cascade theory to incorporate more complex food web structures driven by multi-chain predators provides a conceptual framework for analysis of reticulate food webs in ecosystems.

Abstract: Omnivory has been implicated in both diffusing and intensifying the effects of consumer control in food chains. Some have postulated that the strong, community level, top-down control apparent in lakes is not expressed in terrestrial systems because terrestrial food webs are reticulate, with high degrees of omnivory and diverse plant communities. In contrast, lake food webs are depicted as simple linear chains based on phytoplankton-derived energy. Here, we explore the dynamic implications of recent evidence showing that attached algal (periphyton) carbon contributes substantially to lake primary and secondary productivity, including fish production. Periphyton production represents a cryptic energy source in oligotrophic and mesotrophic lakes that is overlooked by previous theoretical treatment of trophic control in lakes. Literature data demonstrate that many fish are multi-chain omnivores, exploiting food chains based on both littoral and pelagic primary producers. Using consumer-resource models, we examine how multiple food chains affect fourth-level trophic control across nutrient gradients in lakes. The models predict that the stabilizing effects of linked food chains are strongest in lakes where both phytoplankton and periphyton contribute substantially to production of higher trophic levels. This stabilization enables a strong and persistent top down control on the pelagic food chain in mesotrophic lakes. The extension of classical trophic cascade theory to incorporate more complex food web structures driven by multi-chain predators provides a conceptual framework for analysis of reticulate food webs in ecosystems.

Abstract: Zooplankton sampling at Station 18 off Concepcion (36°30′S and 73°07′W), on an average frequency of 30 days (August 2002 to December 2005), allowed the assessment of seasonal and inter-annual variation in zooplankton biomass, its C and N content, and the community structure in relation to upwelling variability. Copepods contributed 79% of the total zooplankton community and were mostly represented by Paracalanus parvus, Oithona similis, Oithona nana, Calanus chilensis, and Rhincalanus nasutus. Other copepod species, euphausiids (mainly Euphausia mucronata), gelatinous zooplankton, and crustacean larvae comprised the rest of the community. Changes in the depth of the upper boundary of the oxygen minimum zone indicated the strongly seasonal upwelling pattern. The bulk of zooplankton biomass and total copepod abundance were both strongly and positively associated with a shallow ( 5 mg m−3). No major changes in zooplankton biomass and species were found from one year to the next. We concluded that upwelling is the key process modulating variability in zooplankton biomass and its community structure in this zone. The spring/summer increase in zooplankton may be largely the result of the aggregation of dominant copepods within the upwelling region; these may reproduce throughout the year, increasing their C content and C/N ratios given high diatom concentrations.

Abstract: While there are countless texts published on quantitative methods and many texts that cover quantitative terrestrial ecology, this text fills the need for the special quantitative problems confronting marine biologists and biological oceanographers. The author combines common quantitative techniques with recent advances in quantitative methodology and then demonstrates how these techniques can be used to study marine organisms, their behaviors, and their interactions with the environment. Readers learn how to better design experiments and sampling, employ sophisticated mathematical techniques, and accurately interpret and communicate the results.
