Abstract:

The parasitic copepod family Ergasilidae currently comprises 26 genera and more than 180 species, the great majority of which utilises marine, brackish and freshwater fishes as hosts. Thirty-three species of Ergasilidae were obtained from examination of the gills of more than 3000 grey mullet preserved in the collections of the Natural History Museum. These species represent nine current genera of the family Ergasilidae: Acusicola, Dermoergasilus, Diergasilus, Ergasilus, Paraergasilus, Nipergasilus, Paeonodes, Mugilicola and Therodamas.

My thesis focuses on copepod-diatom interactions, specifically on the effects of food quality and toxicity on copepod feeding, reproductive success and behavior but as a frame, also includes a quantitative evaluation of copepod carbon requirements compared to other trophic plankton groups. My aim was to evaluate the function of copepods in diatom-dominated spring blooms. I thereby used a series of mesocosm and laboratory experiments. For a realistic extrapolation of the results to natural environments I used different strains of a diatom species, Skeletonema marinoi, which is a common spring b

Abstract:

Production and recruitment measurements in marine copepods of the genus Calanus have been addressed via the study of genes involved in early embryogenesis. The first sequence from a Calanus helgolandicus (C. helgolandicus) developmental gene (Cal-Antp) has been cloned by screening a C. helgolandicus genomic library with a homologous Calanus homeobox probe. Sequencing of an isolated and sub-cloned fragment of this gene, plus further analysis by Inverse Polymerase Chain Reaction (IVPCR), has shown it to be homologous with other Antennapedia homeobox genes. The temporal expression of Cal-Antp was

Abstract:

Abundance-occupancy relationships (AORs), namely the generally positive relationship between species’ mean local abundance and regional distribution represent the most ubiquitous macroecological pattern found in nature. Their importance lies in that they link local population processes to larger scale population structure. However, they exhibit much variability in shape and form and attempts to untangle the variety of processes proposed to underlie them indicates that interpretation of AORs is highly context specific and dependent on the temporal and spatial scales of both data and analyses.

Calanus helgolandicus is a key copepod species occurring in the North East Atlantic that is responding to oceanic warming through an expansion of its geographic range.

I focus specifically on the role of mortality, as a key life history process that is challenging to quantify and historically has received little attention. C. helgolandicus abund

Internal waves are ubiquitous features in coastal marine environments and have been observed to mediate vertical distributions of zooplankton in situ. Internal waves create fine-scale hydrodynamic cues that copepods and other zooplankton are known to sense, such as fluid density gradients and velocity gradients (quantified as shear deformation rate). The role of copepod behavior in response to cues associated with internal waves is largely unknown. The objective is to provide insight to the bio-physical interaction and the role of biological versus physical forcing in mediating organism distr

Copepods in high elevation lakes and ponds in Colorado are exposed to significant levels of ultraviolet radiation (UV), necessitating development of UV avoidance behavior and photoprotective physiological adaptations.

Astaxanthin interacts with a crustacyanin-like protein, shifting its absorbance from 473 nm (hydrophobic free form, appears red) to 632 nm (protein-bound complex, appears blue).

Abstract:

In recent years there has been growing environmental concern regarding ‘microplastics’: microscopic plastic granules, fibres and fragments, categorised as <1 or <5 mm diameter. Microplastics are manufactured to be of a microscopic size, or derive from the photo- and mechanical degradation and subsequent fragmentation of larger plastic litter. Microplastics debris has been identified in the water column and sediments of marine and freshwater ecosystems across the globe, although difficulties in sampling and isolating smaller particulates has resulted in the abundance of <333 µm microplastics be

Abstract:

xxii, 242 p. : ill. (some col.)<br>The arminacean nudibranch Janolus fuscus (family Zephyrinidae) is found in rocky intertidal habitats along the northeast Pacific coast. Adult J. fuscus are conspicuous from April to October but absent in the early winter at two sites, North Cove and Fossil Pt., in the Coos Bay region of Oregon. Over four years of intertidal surveys at these sites, the density of J. fuscus peaked with the abundance of their bryozoan prey, Bugula pacifica and Tricellaria circumternata , in spring and summer, while adult absence in winter was correlated with strong winter storms
