During our study of this species, we have worked on specimens from France, Greece, Tunisia and Re union island. Laboratory crosses have revealed two separate groups of populations: French populations (four localities) in one group, and those from Tunisia, Re union island and Greece in the other. French individuals were reproductively isolated from those of the other populations. We have undertaken a survey of mitochondrial DNA (mtDNA) polymorphism in these seven populations. We observed two groups of mitotypes corresponding to the two groups of populations. Interfertility experiments between populations and the mitochondrial genetic distances between mitotypes both suggest the presence of two dierent species, one in France and one in Greece, Tunisia and Re union island. The two species harbour, respectively, two dierent Wolbachia lines. Another feature of the molecular genetic analysis was the apparent mitochondrial monomorphism in the French populations and the low variability

The genetic structure of several populations belonging to different subspecies (diploid bisexual, triploid parthenogenetic; epigean, troglophilic and troglobitic) was assessed by investigating 10 enzymatic systems corresponding to 15 putative loci. F-statistics and cluster- ing analysis indicated a high degree of genetic differentiation, corresponding to low levels of gene flow among populations, both epigean and hypogean, still considered to be conspecific. Estimates of divergence times calculated from genetic distance data suggest that the pattern of differentiation and the colonization of cave environments may be related to the palaeoclimatic change of the Messinian and PIio—Pleistocene glaciations.

The Institute studies the factors determining the structure, composition and processes of land and freshwater systems, and of individual plant and animal species. It is developing a sounder scientific basis for predicting and modelling environmental trends arising from natural or man- made change. The results of this research are available to those responsible for the protection, management and wise use of our natural resources. One quarter of ITE's work is research commissioned by customers, such as the Department of Environment, the European Economic Community, the Nature Conservancy Council and the Overseas Development Administration.

E-mail: [email protected] 3 4 Mount Pleasant Cottages, Church Street, East Hendred, Oxfordshire, OX12 8LA, UK. E-mail: [email protected] INTRODUCTION The 2014 BMIG field weekend, held from 24th to 27th April, was based at Saughy Rigg, half a mile north of Hadrian’s Wall, near Haltwhistle in Northumberland but very close to the border with Cumbria to the west and Scotland to the north. The main aim of the meeting was to record in central areas of northern England (VC 66, 67 and 70) where few records existed previously but many attendees were drawn also to sites on the east coast of England (VC 66) and to the Scottish coast on the Solway Firth (VC 73). All these vice counties had been visited by BMG/BISG or BMIG in the previous twenty years but large parts of them remained under-recorded. The annual joint field meeting of BMG and BISG in 1995 was held at Rowrah Hall near Whitehaven (VC 70). Gregory (1995) reports 24 millipede species found during the weekend including Choneiulus palmatus new to VC 70. A list of the centipede appears not to have been published. Bilton (1995) reports 14 woodlouse species including Eluma caelata found at Maryport, its most northerly global location, and Armadillidium pictum in the Borrowdale oakwoods.

  • COLOUR POLYMORPHISM in the LAND ISOPOD Dealt with the Frequency of Genes in Populations. Howard
    COLOUR POLYMORPHISM IN THE LAND ISOPOD ARMADILLIDIUM NASATUM* S. LAURA ADAM KEWICZt Department of Biology, University of Virginia Received7.vj.68 1. INTRODUCTION Armadillidium nasatum Budde-Lund is one of the commonest oniscoid isopods in the south-eastern United States (Schultz, 1961). In Albemarle County, Virginia, and probably throughout its range, the species is polymorphic for body colour. The Oniscoidea as a whole are quite variable in colour and pattern (Vandel, 1960, 1962), and several workers have studied the genetics of individual loci (for references see Vandel, 1945, 1962). Only two have dealt with the frequency of genes in populations. Howard (1940, 1953, 1962) has investigated the genetics of Armadillidium vulgare with some attention to populations. De Lattin (1939, 1951, 1954) has studied the genetics of albinism and marbling in many species and has determined gene frequencies in some of them. However, neither study has seriously attempted to discover the causes for the polymorphisms. An extensive literature is available on the taxonomy (Vandel, 1960, 1962), physiology (Edney, 1954), and ecology (Hatchett, 1947; Brereton, 1957; Paris, 1962, 1963; Warburg, 1965) of land isopods. These works provide all the necessary background for investigations of population genetics in this large and widespread group of animals. Therefore, it seems important to apply to A. nasatum the techniques of ecological genetics so successfully used for other animals (Fisher and Ford, 1947; Cain and Sheppard, 1954; Dowdeswell, 1961). 2. METHODS (a) Collections All of the isopods used in this study were collected from natural popula- tions in Albemarle County, Virginia, from September 1964 to May 1968.

From Ecology of Center City, Philadelphia by Kenneth D. Frank. Published in 2015 by Fitler Square Press, Philadelphia, PA. In the first volume of the Journal of the Academy of Natural Sciences of Philadelphia, pub- lished in 1818, Thomas Say presented “An Account of the Crustacea of the United States.” Crustacea are arthropods such as lobsters, crabs, shrimp, barnacles, and four- teen-legged creatures called isopods. Terrestrial isopods include familiar garden ani- mals known by many colloquial names, such as woodlice, sowbugs, roly-polies, and pillbugs. Say noted that one species, currently named Armadillidium vulgare, “is very common in moist places, under stones, in decaying wood, &c.”2 This species inhabits our garden in Center City. Figure 16.2 Our Center City row house garden, habitat for a diverse community of exotic animals, including six species of isopods, such as pillbugs. Introduction of pillbugs Unlike the Chinese mantid, A. vulgare in North America left no obvious clues to its place of origin. A genetic study of 10,000 of these pillbugs in 157 populations in Europe and North America concluded that this species was introduced from north- ern Europe.3 Root balls in imported horticultural and agricultural stock could have carried it in, or dirt used in ship ballast dumped near American ports could have transported it here.

All known parasitoids are from the family Rhinophoridae (Insecta: Diptera). The present article reviews the known biology of Rhinophoridae flies and presents the first record of Rhinophoridae larvae on a Neotropical woodlouse species. We also compile and update all published interaction records. The Neotropical wood- louse Balloniscus glaber was parasitized by two different larval morphotypes of Rhinophoridae.
