However, despite their ecological importance, their genome has not Gammarus fossarum yet been completely annotated and molecular mechanisms underlying key pathways, such as the serotonin RNA sequencing pathway, in development of ecotoxicological biomarkers of exposure to neuroactive pharmaceuticals are still De novo assembly poorly understood. Furthermore, genetic similarities and discrepancies with other model arthropods (e.g., Serotonin pathway Drosophila melanogaster) have not been completely clarified. In this report, we present a new transcriptome assembly of Gammarus fossarum, an important amphipod species, widespread in Central Europe. RNA-Seq with Illumina HiSeq technology was used to analyse samples extracted from total internal tissues. We used the Trinity and Trinotate software suites for transcriptome assembly and annotation, respectively. The quality of this as- sembly and the affiliated targeted homology searches greatly enrich the molecular knowledge on this species. -

Editorial note On the publication “On the current state of taxonomy of the Baikal Lake amphipods (Crustacea, Amphipoda) and the typological ways of constructing their system” by V.V. Takhteev In this issue we present an extensive article prepared by Prof. Vadim V. Takhteev, which is based on his long time effort in the study of diversity of amphipods in Lake Baikal and its watershed. This paper is highly polemical and may even seem either archaic or heretical in the time of domination of the phylogenetic paradigms in systematics. The author advocates classical morphological taxonomy, which own tradition, methods (disregarding whether we call it typology or not) and the language are significantly older than the modern phylogenetic approach. -

Specifically, we looked at Funding information the impacts of the acanthocephalan Acanthocephalus galaxii, the trematodes Department of Zoology, University of Otago Coitocaecum parvum and Maritrema poulini, and the nematode Hedruris spinigera, on three host species: the amphipods, Paracalliope fluviatilis and Paracorophium excava- tum, and the isopod, Austridotea annectens. We assessed parasite infection levels in the three host species and tested for effects on host survival, behavior, probability of pairing, and fecundity. Maritrema poulini and C. parvum were most abundant in P. exca- vatum but had no effect on its survival, whereas they negatively affected the survival of P. fluviatilis, the other amphipod. Female amphipods carrying young had higher M. poulini and C. parvum abundance than those without, yet the number of young car- ried was not linked to parasite abundance. Behavior of the isopod A. annectens was affected by M. poulini infection; more heavily infected individuals were more active. Paracorophium excavatum moved longer distances when abundance of C. -

Ecotoxicology of Estuarine Amphipod Paracorophium Excavatum
E icolo fEstua ·ne Amphipod Paracorophium excavatum A thesis Submitted in partial fulfilment the requirements for Degree of Master of Science in Environmental Science at The University of Canterbury by Carol Wong Hee Ting University of Canterbury 1999 ABSTRACT The estuarine tube dwelling amphipod Paracorophium excavatum was investigated for its suitability as a bio-indicator and bio-monitor. Distribution patterns of P. excavatum were determined at 13 sites in the Canterbury region that differed in particle size distribution ranging from sandy to muddy sediment, with overall10w organic content. Low tide salinity ranged from 5 to 33 0/00 between sites and sediment moisture content ranged between 23 to 41 % moisture. Amphipods were absent from most sites within the Avon-Heathcote Estuary. The availability, life history and fecundity of P. excavatum were compared from intertidal mudflat sites in Brooklands Lagoon and Kairaki over a period of thirteen months. Four sediment core samples were collected at monthly intervals and P. excavatum IS population structure and life history pattern studied. The life history til· <: of P. excavatum can be characterised bY fast-growing, annual, iteroporous, bivoltine, females ovigerous throughout the year and thelygenous (female biased) population. P. excavatum showed relative consistency in abundance throughout the year with monthly densities ranging from 875.79 per 0.1 m-2 (July) to 1754.77 per 0.1 m-2 (December) at Brooklands Lagoon and 1031.83 per 0.1 m2 (November) to 1780.24 per 0.1 m2 (December) at Kairaki. There was a linear relationship between numbers of eggs per female and female length. -

With 3 figures Population genetic structure of New Zealand’s endemic corophiid amphipods: evidence for allopatric speciation MARK I. STEVENS* and IAN D. HOGG Centre for Biodiversity and Ecology Research, Department of Biological Sciences, University of Waikato, Private Bag 3105, Hamilton, New Zealand Received 2 January 2003; accepted for publication 28 July 2003 Allozyme electrophoresis was used to examine population genetic structure at inter- and intraspecific levels for the New Zealand endemic corophiid amphipods, Paracorophium lucasi and P. excavatum. Individuals were collected from estuarine and freshwater habitats from North, South and Chatham Islands. Analyses of genetic structure among interspecific populations indicated clear allelic differentiation between the two Paracorophium species (Nei’s genetic distance, D = 1.62), as well as considerable intraspecific substructuring (D = 0.15–0.65). These levels of diver- gence are similar to interspecific levels for other amphipods and it is proposed that at least two groups from the P. lucasi complex and three from the P. excavatum complex correspond to sibling species. In most cases allopatry can account for the differentiation among the putative sibling species. For populations that share a common coastline we found low levels of differentiation and little or no correlation with geographical distance, suggesting that gene flow is adequate to maintain homogeneous population genetic structure. By contrast, populations on separate coastlines (i.e. -
Molecular Data Suggest Multiple Origins and Diversification Times Of
www.nature.com/scientificreports OPEN Molecular data suggest multiple origins and diversifcation times of freshwater gammarids on the Aegean archipelago Kamil Hupało1,3*, Ioannis Karaouzas2, Tomasz Mamos1,4 & Michał Grabowski1 Our main aim was to investigate the diversity, origin and biogeographical afliations of freshwater gammarids inhabiting the Aegean Islands by analysing their mtDNA and nDNA polymorphism, thereby providing the frst insight into the phylogeography of the Aegean freshwater gammarid fauna. The study material was collected from Samothraki, Lesbos, Skyros, Evia, Andros, Tinos and Serifos islands as well as from mainland Greece. The DNA extracted was used for amplifcation of two mitochondrial (COI and 16S) and two nuclear markers (28S and EF1-alpha). The multimarker time- calibrated phylogeny supports multiple origins and diferent diversifcation times for the studied taxa. Three of the sampled insular populations most probably represent new, distinct species as supported by all the delimitation methods used in our study. Our results show that the evolution of freshwater taxa is associated with the geological history of the Aegean Basin. The biogeographic afliations of the studied insular taxa indicate its continental origin, as well as the importance of the land fragmentation and the historical land connections of the islands. Based on the fndings, we highlight the importance of studying insular freshwater biota to better understand diversifcation mechanisms in fresh waters as well as the origin of studied Aegean freshwater taxa. Te Mediterranean islands are considered natural laboratories of evolution, exhibiting high levels of diversity and endemism, making them a vital part of one of the globally most precious biodiversity hotspots and a model system for studies of biogeography and evolution1–4.
