Sars, 1907 (Crustacea: Mysidacea) was recorded for the first time in the Netherlands in 1997. In the summer of 1998 extremely high den- sities (>6 ind. 1-1) of this neozoon were recorded in one of the Biesbosch reservoirs (Honderd en Dertig). This high abundance can not be explained by a recent invasion. Either H. anomala reached the Nether- lands via the River Rhine, probably aided by shipping, or through transport with ballast water from the Baltic or Black Sea. The invasion had dramatic effects on the zooplankton composition and abundance: from the end of August onwards hardly any Anomopoda, Ostracoda, Rotifera and invertebrate predators (Leptodora kindti and Bythotrephes longimanus) were present. -

The Life Cycle of the Parasite Pomphorhynchus Tereticollis in Reference to 0+ Cyprinids and the Intermediate Host Gammarus Spp in the UK
March 2020 The life cycle of the parasite Pomphorhynchus tereticollis in reference to 0+ cyprinids and the intermediate host Gammarus spp in the UK. Matthew J Harris Thesis submitted in partial fulfilment of the requirements of the degree of Master’s By Research Bournemouth University Supervisory team; Iain Green, Robert Britton and Demetra Andreou Acknowledgments I would like to thank all of my supervisors for the support they have given me through the project in regard to their enormous plethora of knowledge. In particular I would like to thank Dr Demetra Andreou as without her support, motivation and can-do attitude I may not have been able to finish this project. It was also Dr Andreou who originally inspired me to purse Parasitological studies and without her inspiration in my undergraduate studies, it is unlikely I would have studied a MRes as parasitology bewilders me like no field I have ever come across. I would also like to thank Dr Catherine Gutman-Roberts for allowing me access to samples that she had previously collected. As well as this, Dr Gutmann-Roberts was always helpful and friendly when questions were directed at her. Finally, I would also like to thank her for the help she gave to me regarding field work. Abstract Pomphorhynchus tereticollis is a recently resurrected parasite species that spans the UK and continental Europe. The parasite is the only Pomphorhynchus spp in the UK and has been researched since the early 1970’s. The species has an indirect life cycle which uses a Gammarus spp as an intermediate host and cyprinids and salmonids as final hosts although the main hosts are Squalis cephalus (S. -

Nickol 9.1 Introduction In practice, epizootiology deals with how parasites spread through host populations, how rapidly the spread occurs and whether or not epizootics result. Prevalence, incidence, factors that permit establishment ofinfection, host response to infection, parasite fecundity and methods of transfer are, therefore, aspects of epizootiology. Indeed, most aspects of a parasite could be related in sorne way to epizootiology, but many ofthese topics are best considered in other contexts. General patterns of transmission, adaptations that facilitate transmission, establishment of infection and occurrence of epizootics are discussed in this chapter. When life cycles are unknown, little progress can be made in under standing the epizootiological aspects ofany group ofparasites. -

In 59 specimens of Sq.orpheus, four specimens of intestinal helminths are fixed (Allocreadium isoporum (Kowal et Kulakowskaja, 1957); Caryophyllaeus brachycollis (Janiszewska, 1951); Pomphorhynchus laevis (Müller, 1776); Rhabdochona denudata (Dujardin, 1845)). P. laevis is distinguished with the highest prevalence and mean intensity (66.10% and 1.85, respectively). A. isoporum, P. laevis and Rh. denudata are core species for the helminth communities of Orpheus dace, while C. brachycollis is a component species. The eutrophication effects on the pathways of the parasitic flow and the structure of the helminth communities were traced. The bioindicator significance of the parasitic complexes was discussed.

Diel Horizontal Migration of Zooplankton: Costs and Benefits Of
Freshwater Biology (2002) 47, 343–365 FRESHWATER BIOLOGY SPECIAL REVIEW Diel horizontal migration of zooplankton: costs and benefits of inhabiting the littoral R. L. BURKS,* D. M. LODGE,* E. JEPPESEN† and T. L. LAURIDSEN† *Department of Biological Sciences, University of Notre Dame, Notre Dame, IN, U.S.A. †Department of Lake and Estuarine Ecology, National Environmental Research Institute, Vejlsøvej, Silkeborg, Denmark SUMMARY 1. In some shallow lakes, Daphnia and other important pelagic consumers of phyto- plankton undergo diel horizontal migration (DHM) into macrophytes or other structures in the littoral zone. Some authors have suggested that DHM reduces predation by fishes on Daphnia and other cladocerans, resulting in a lower phytoplankton biomass in shallow lakes than would occur without DHM. The costs and benefits of DHM, and its potential implications in biomanipulation, are relatively unknown, however. 2. In this review, we compare studies on diel vertical migration (DVM) to assess factors potentially influencing DHM (e.g. predators, food, light, temperature, dissolved oxygen, pH). We first provide examples of DHM and examine avoidance by Daphnia of both planktivorous (PL) fishes and predacious invertebrates. 3. We argue that DHM should be favoured when the abundance of macrophytes is high (which reduces planktivory) and the abundance of piscivores in the littoral is sufficient to reduce planktivores. Food in the littoral zone may favour DHM by daphnids, but the quality of these resources relative to pelagic phytoplankton is largely unknown. 4. We suggest that abiotic conditions, such as light, temperature, dissolved oxygen and pH, are less likely to influence DHM than DVM because weaker gradients of these conditions occur horizontally in shallow lakes relative to vertical gradients in deep lakes. -

We investigated the influence of different salinity regimes on thermotolerance, energy metabolism and cellular stress defense mechanisms in amphipods Gammarus lacustris Sars from two populations. We exposed amphipods to different thermal scenarios and determined their survival as well as activity of major antioxidant enzymes (peroxidase, catalase, glutathione S-transferase) and parameters of energy metabolism (content of glucose, glycogen, ATP, ADP, AMP and lactate). Amphipods from a freshwater population were more sensitive to the thermal challenge, showing higher mortality during acute and gradual temperature change compared to their counterparts from a saline lake. A more thermotolerant population from a saline lake had high activity of antioxidant enzymes. The energy limitations of the freshwater population (indicated by low baseline glucose levels, downward shift of the critical temperature of aerobic metabolism and inability to maintain steady-state ATP levels during warming) was ob- Submitted 26 July 2016 served, possibly reflecting a trade-off between the energy demands for osmoregulation Accepted 5 October 2016 under the hypo-osmotic condition of a freshwater environment and protection against Published 17 November 2016 temperature stress. -
Northern Spring Amphipod Gammarus Pseudolimnaeus
Natural Heritage Northern Spring Amphipod & Endangered Species Gammarus pseudolimnaeus Program State Status: Special Concern www.mass.gov/nhesp Federal Status: None Massachusetts Division of Fisheries & Wildlife DESCRIPTION: The Northern Spring Amphipod is a laterally compressed, many segmented, freshwater crustacean that looks like a small, flat shrimp. It is uniformly dark and mature specimens can reach lengths of 11 to 18 mm (Bousfield 1958, Bell 1971, Hynes and Harper 1972). Its head has two pairs of antennae and a pair of eyes, and is fused with the first of seven thoracic segments. Each thoracic segment, as well as the six abdominal segments, has a pair of legs and/or gills that aid in respiration and locomotion. Identification of amphipods is difficult because knowledge of specific 2 mm amphipod anatomy is required. male SIMILAR SPECIES: Amphipods in the genus Gammarus are similar to this species. Gammarus Smith, D.G. 1984. Selected freshwater invertebrates proposed for special concern status in Massachusetts, Part II. Mass. Dept. of Env. Qual. fasciatus is most similar in that it is uniformly colored, Engineering, Div. of Wat. Pollut. Control. Westborough, MA. although it is smaller and has conspicuous dark bands. Identification guides sufficiently illustrate the differences among these species (Smith 2000). RANGE: The range of the Northern Spring Amphipod extends throughout the previously glaciated regions of New York and the Great Lakes region. Three localities in southwestern Massachusetts and an isolated locality in the central Hudson River system in New York represent the currently known southeastern range limit of the species along the Atlantic seaboard. The Massachusetts populations appear to be the only populations in New England and are possibly glacial relict populations (D.G. -
