Progress in our understanding of phylogenetic relationships within the Crustacea is linked to continuing discoveries of new taxa, to advances in theory and to improvements in methodology. Six themes are discussed that serve to illustrate some of the major on-going controversies and unresolved problems in the field as well as to illustrate changes that have taken place since the time of Linnaeus. These themes are: 1. the treatment of parasitic Crustacea, 2. the affinities of the Remipedia, 3. the validity of the Entomostraca, 4. exopodites and epipodites, 5. using larval characters in estimating phylogenetic rela- tionships, and 6. fossils and the crustacean stem-lineage. It is concluded that the development of the stem lineage concept for the Crustacea has been dominated by consideration of taxa known only from larval or immature stages. -

Phillips, Victoria Overmeyer Biology Program, College of Science and Mathematics, University of South Florida Sarasota-Manatee, Sarasota, FL, 34243, USA v1 First published: 30 Aug 2017, 6:1602 (doi: 10.12688/f1000research.12459.1) Open Peer Review Latest published: 30 Aug 2017, 6:1602 (doi: 10.12688/f1000research.12459.1) Referee Status: Abstract Ligia isopods exhibit a constrained morphology that makes identification difficult. In the Greater Caribbean, a convoluted taxonomic history has left the Invited Referees distributional limits of Ligia baudiniana unclear. To date, no confirmed records 1 2 of this species exist from the American Gulf of Mexico. Herein, we report the presence of L. baudiniana in Sarasota-Manatee Florida, as confirmed by version 1 morphological and molecular approaches. This is the first record of this species published report report in the region and a ~300Km extension of its range. Specimens were collected 30 Aug 2017 in mangroves, underscoring the importance of protecting these habitats. 1 Mary K.

Malacostraca, Isopoda, Oniscidea) of Nature Reserves in Poland
B ALTIC COASTAL ZONE Vol. 24 pp. 65–71 2020 ISSN 2083-5485 © Copyright by Institute of Modern Languages of the Pomeranian University in Słupsk Received: 7/04/2021 Original research paper Accepted: 26/05/2021 NEW INFORMATION ON THE WOODLOUSE FAUNA (MALACOSTRACA, ISOPODA, ONISCIDEA) OF NATURE RESERVES IN POLAND Artsiom M. Ostrovsky1, Oleg R. Aleksandrowicz2 1 Gomel State Medical University, Belarus e-mail: [email protected] 2 Institute of Biology and Earth Sciences, Pomeranian University in Słupsk, Poland e-mail: [email protected] Abstract This is the fi rst study on the woodlouse fauna of from 5 nature reserves in the Mazowian Lowland (Bukowiec Jabłonowski, Mosty Kalińskie, Łosiowe Błota, Jezioro Kiełpińskie, Klimonty) and from 2 nature reserves in the Pomeranian Lake District (Ustronie, Dolina Huczka) are presented. A total of 8 species of woodlice were found. The number of collected species ranged from 1 (Dolina Chuczka, Mosty Kalińskie, Klimonty) to 5 (Łosiowe Błota). The most common species in the all studied reserves was Trachelipus rathkii. Key words: woodlouse fauna, nature reserves, Poland, Isopoda, species INTRODUCTION Woodlice are key organisms for nutrient cycling in many terrestrial ecosystems; how- ever, knowledge on this invertebrate group is limited as for other soil fauna taxa. By 2004, the world’s woodlouse fauna (Isopoda, Oniscidea) included 3637 valid species (Schmalfuss 2003). The fauna of terrestrial isopods in Europe has been active studied since the beginning of the XX century and is now well studied (Jeff ery et al. 2010). In Poland 37 isopod species inhabiting terrestrial habitats have been recorded so far, including 12 in Mazovia and 16 in Pomerania (Jędryczkowski 1979, 1981, Razowski 1997, Piksa and Farkas 2007, Astrouski and Aleksandrowicz 2018). -
Genetic Differentiation and Natural Hybridization Between Two Morphological Forms of the Common Woodlouse, Oniscus Asellus Linnaeus 1758
Heredity 82 (1999) 462±469 Received 16 September 1998, accepted 13 January 1999 Genetic differentiation and natural hybridization between two morphological forms of the common woodlouse, Oniscus asellus Linnaeus 1758 D. T. BILTON* , D. GOODEà & J. MALLET§à Department of Biological Sciences and Plymouth Environmental Research Centre, University of Plymouth, Drake Circus, Plymouth PL4 8AA, U.K., àNatural History Museum, Cromwell Road, London SW7 5BD, U.K. and §Galton Laboratory, Department of Biology, University College London, 4 Stephenson Way, London NW1 2HE, U.K. The common woodlouse Oniscus asellus can be divided into two forms on the basis of morphology, particularly male accessory genitalia. Where these taxa meet, morphological intermediates are found, and the forms were therefore described as subspecies; O. a. asellus and O. a. occidentalis. In this study allozyme loci are used to test the hypothesis that intermediate forms result from hybridization, and to study the nature of hybridization. Thirteen enzyme loci were scored across ®ve English sites representative of each subspecies and intermediates. Ten loci showed strong frequency dierences between asellus and occidentalis populations, although no loci showed completely ®xed dierences. These data con®rm that asellus and occidentalis represent genetically distinct taxa, and that intermediate populations are of hybrid origin. There is apparently substantial population substruc- turing in the contact zone, as indicated by de®cits of heterozygotes (FIS) and sporadic gametic (i.e. linkage) disequilibria. Population structure in the Oniscus hybrid zone appears to be analogous to that seen in plant hybrid swarms rather than the narrow hybrid zones observed in many animal taxa. Values of Nei's genetic distance between the subspecies range from 0.65 to 0.70; these are much higher than between typical conspeci®c taxa and are indicative of ancient genetic divergence. -

Notes on Terrestrial Isopoda Collected in Dutch Greenhouses
NOTES ON TERRESTRIAL ISOPODA COLLECTED IN DUTCH GREENHOUSES by L. B. HOLTHUIS On the initiative of Dr. A. D. J. Meeuse investigations were made on the fauna of the greenhouses of several Botanic Gardens in the Netherlands; material was also collected in greenhouses of other institutions and in those kept for commercial purposes. The isopods contained in the col• lection afforded many interesting species, so for instance six of the species are new for the Dutch fauna, viz., Trichoniscus pygmaeus Sars, Hylonis- cus riparius (Koch), Cordioniscus stebbingi (Patience), Chaetophiloscia balssi Verhoeff, Trichorhina monocellata Meinertz and Nagara cristata (Dollfus).

Investigation of Symbionts of Isopods
Bacterial communities in the hepatopancreas of different isopod species Renate Eberl University of California, Davis ABSTRACT: This study aims to describe animal bacterial associations with culture independent methods. Bacterial communities in the hepatopancreas of the following 7 species of isopods (Pericaridea, Crustacea, Arthropoda) from 3 habitat types were investigated: 2 subtidal species Idotea baltica (IB) and I. wosnesenskii (IG); 2 intertidal species Ligia occidentalis (LO) and L. pallasii (LP), and 3 terrestrial species Armadillidium vulgare (A), Oniscus asellus (O) and Porcelio scaber (P) Oniscus asellus (O) and Porcelio scaber (P). CARD FISH and 16S clone libraries form environmental samples isolated from the hepatopancreas of isopods were used to describe the bacterial communities. Previous work has described two species of symbionts of terrestrial isopods and found very low diversity (predominately only one species per host). Clone libraries from some but not all species in this study included sequences closely related to previously described isopod symbionts with the majority clustering around Candidatus Hepatoplasma crinochetorum (Firmicutes, Mollicutes). These sequences clustered by host species confirming published results of host specificity. Closely related sequences to the other described symbiont 'Candidatus Hepatincola porcellionum' (α-Proteobacteria, Rickettsiales) were only obtained from the hepatopancreas of L. pallasii. Counts of bacterial abundance obtained with CARD FISH (Probe EUB I-III) ranged between 1.9 x 103 – 1.7 x 104 bacteria per hepatopancreas, this numbers are 2 to 3 orders of magnitude lower than previously published counts of DAPI stained cells. 1 INTRODUCTION: Bacterial associations with animal hosts are important on host functioning. Eukaryotes in a number of phyla have overcome their limitations in nutritional capabilities by associating with microorganisms. -
