En masse foraging migrations of Ligia occidentalis Dana were conspicuous events on rocky beaches near Puerto Peñasco, Sonora, Mexico. Experiments were conducted to determine which factors of the environment contained the regulating rhythm for the migration, if indeed the event were cyclic. Experiments were conducted in the laboratory using a tide-simulation aquarium and in the field using mark and release techniques. A time-lapse photography system was used in the field to quantify isopod activity for comparison with environmental factors. A regular cycle for the foraging migration was found. It was in tune with both insolation and tidal cycles so that the isopods began their migrations at the low tides which commenced uncovering the lower intertidal zones during daylight. This resulted in a sudden shift of isopod activity from the evening low tide to the morning low tide when the tides reached spring phase.

Mesidotea entomon inhabiting Pauline Cove, YT, is larger in total body length at sexual maturity than M. entomon inhabiting Dolomite Lake, NWT. The sex ratio, diet, habitat distributions, size frequency distributions, and fecundity in the two populations are compared. Total carbohydrate, protein, lipid, chitin, and ash contents of both isopods' life stages are compared. Isopods in the cove show reduced carbohydrate and elevated lipid levels. In the 1975, 1978, and 1979 summers, isopods in the cove were internally infected with an extracellular protozoan parasite; those in the lake were uninfected. The infection is systemic. The prevalence of the protozoan infection increases with increasing host size. The host response involved phagocytosis and encapsulation. Transmission may be transovarially and/or by ingestion of the infective stage. The protozoan also infected Mesidotea sibirica. The infection is related to growth, abundance, habitat, reproduction, and biochemical variables.

Foi realizada uma revisão taxonômica das espécies que ocorrem no oeste do oceano Atlântico (totalizando 66), e uma análise distribucional utilizando o Método de Análise Parcimônia de Endemismo (PAE). O material se encontra depositado nas coleções de carcinologia do Museu de Oceanografia da Universidade Federal de Pernambuco, Museu Nacional do Rio de Janeiro e no Museu de Zoologia da USP. Com o estudo dessas amostras foi possível propor nova chave de identificação, atualizando as já existentes para o Oceano Atlântico, incluindo as espécies descritas mais recentemente. Os exemplares estudados foram dissecados e desenhados com auxílio de microscópio e estereomicroscópio com câmara clara acoplada. Os exemplares foram corados em negro de clorazol e suas peças montadas em lâminas semi-permanentes com gelatina glicerinada. Os desenhos digitais foram confeccionados no programa gráfico Corel Draw®. Foram encontradas oito espécies distribuídas em seis gêneros, sendo dois registros novos, um do gênero Bathynomus (B. miyarei) e outro do gênero Calyptolana (C. hancocki). Foram resistradas seis espécies novas para ciência: duas de Cirolana sp. nov. A, C. sp. nov.B, Dolicholana brucei, D. sp. nov., Natatolana sp. nov., Politolana sp. nov. Dentre as espécies estudadas B. miyarei, C. sp. nov. A, C. sp. nov. B, Dolicholana brucei, D. sp. nov., Natatolana sp. nov., Politolana sp. nov. até o momento são endêmicas para o Brasil. Com base nos dados levantados nessa pesquisa foram descritas seis espécies novas para a costa Brasileira, incluindo regiões de água rasa e mar profundo. Além disso, foram registrados pela primeira vez o gênero Dolicholana Bruce, 1986. A análise de parcimônia de endemismo revelou quatro áreas de endemismo no Atlântico Ocidental, corroborando em parte com algumas propostas já bem estabelecidas na literatura para outros grupos de crustáceos. / There are known 492 species of Family Cirolanidae. It was performed a taxonomic revision of the species occurring in the western Atlantic Ocean (totaling 66), and a distributional analysis using the Parsimony Analysis of Endemicity (PAE). The material analyzed is deposited at carcinology collections of the Oceanography Museum on the Universidade Federal de Pernambuco, National Museum of Rio de Janeiro and on the USP Zoology Museum. With the study of these samples was possible to propose new identification key updating the one which exist to the Atlantic Ocean, including the described species recently. The specimens studied were dissected and drawn with the aid of a microscope and stereo microscope with camera lucida attached. The specimens were stained with dark clorazol and these parts were mounted on semi-permanent slides with glycerinated gelatin. The digital drawings were made in Corel Draw® graphics program. We found eight species distributed in six genera, two new records, a genus of Bathynomus (B. miyarei) and other genus of Calyptolana (C. hancocki). It was registered six new species to science: Two Cirolana sp. nov. A, C. sp nov. B, Dolicholana brucei, D. sp. nov., Natatolana sp. nov., Politolana. sp. nov. Among the species studied B. miyarei, C. sp.nov. A, C. sp. nov. B, Dolicholana brucei, D. sp. nov., Natatolana sp. nov., Politolana sp. nov. are endemics to Brazil up to now. Based on data collected in this study were described six new species to the Brazilian coast, including areas of shallow water and deep sea. Besides that, it was registered to the first time a genus of Dolicholana Bruce, 1986. The parsimony analysis of endemicity revealed four areas of endemicity in the western Atlantic, partly corroborating with some proposals already well established in the literature for others crustacean groups.

Thesis (PhD)--Stellenbosch University, 2002. / ENGLISH ABSTRACT: Metals occur naturally in the environment but since the industrial revolution the amounts ofbioavailable metals in the environment have increased significantly. There are various anthropogenic sources of metals in the environment. In recent years there has been an increasing interest in the use of biomarkers in terrestrial invertebrates for the assessment of the potential adverse effects of chemicals in soil ecosystems. Terrestrial isopods are one of the groups that play an important role in the decomposition process as fragmentors of dead plant material in soil ecosystems. They are also known to accumulate contaminants in their bodies, especially in the hepatopancreas. Cadmium has no known biological function and is deposited in the environment through a variety of sources. Zinc on the other hand is one of the essential metals and play an important role in the normal metabolism of animals. Zinc too, is deposited in the environment through a variety of anthropogenic sources. The aim of this study was to undertake an experimental and field evaluation of the role cellular change in the hepatopancreas of terrestrial isopods can play in conjunction with other sublethal responses to contribute to the assessment of the impact of cadmium and zinc in terrestrial ecosystems. Porcel/io laevis was used as test species in the laboratory experiments in this study, to conduct sublethal toxicity tests. Cadmium- and zinc sulphate were used as the contaminants, applied separately and as mixtures. The isopods were weighed before the beginning of the exposures and every week throughout the exposure period of six weeks. At the end of the exposure period they were dissected to remove the hepatopancreas. The zinc and cadmium content of the hepatopancreases and rest of the bodies of the isopods were determined by atomic absorption spectrophotometry. Hepatopancreas samples were also prepared for histological analysis, and measurements of the Percentage Cellular Area (PCA) were made using image analysis. Specimens of Porcellionides pruinosus were collected from contaminated- and uncontaminated field sites. Hepatopancreas- and rest of the body samples of P. pruinosus were also analysed for cadmium and zinc. Histological sections of the hepatopancreas were similarly prepared and analysed, as in the laboratory experiments. Exposure to cadmium- and zinc sulphate affected the mass of P. laevis negatively in the single metal exposures. However, these two metals "neutralised" each other's effects in the mixture toxicity exposures, pointing towards an antagonistic interaction. Administered cadmium- and zinc sulphate resulted in the accumulation of cadmium and zinc in the isopods, especially in the hepatopancreas. In the mixture toxicity experiments cadmium and zinc influenced the accumulation of each other. Cadmium- and zinc sulphate, whether administered separately or as mixtures, changed the structure of the hepatopancreas and this was quantitatively shown through PCA measurements. PCA of the hepatopancreas of terrestrial isopods was shown to be a good general biomarker of exposure and effects for cadmium as well as for zinc. It is suggested that PCA could serve as a general biomarker to predict possible impairment of growth or mass change of isopods exposed to cadmium and zinc mixtures. The findings of the field survey also suggest that PCA may be suitable to be used as a general biomarker to measure metal induced stress in woodlice from contaminated field sites. / AFRIKAANSE OPSOMMING: Metale kom natuurlik voor in die omgewing, maar sedert die industriële revolusie het die hoeveelheid bio-beskikbare metale in die omgewing betekenisvol toegeneem. Daar is verskeie antropogeniese bronne van metale in die omgewing. Die afgelope paar jaar was daar toenemende belangstelling in die gebruik van biomerkers by terrestriële invertebrate vir die assessering van potensiële negatiewe effekte van chemiese stowwe in grondekosisteme. Terrestriële Isopoda is een van die groepe wat 'n belangrike rol speel III die ontbindingsproses as fragmenteerders van dooie plantmateriaal III grondekosisteme. Hulle akkumuleer ook kontaminante in hul liggame, veral in die hepatopankreas. Kadmium het geen biologiese funksie nie, en word vrygestel in die omgewing deur verskeie bronne. Sink, aan die ander kant, is een van die essensiële metale en speel 'n belangrike rol in die metabolisme van diere. Sink word ook in die omgewing vrygestel deur 'n verskeidenheid antropogeniese bronne. Die doel van die studie was om deur eksperimentele en veldondersoek die rol van sellulêre veranderinge in die hepatopankreas van terrestriële Isopoda in samehang met ander subietale response te evalueer om by te dra tot die assessering van die impak van kadmium en sink op terrestriële ekosisteme. Porcellio laevis is as toets-spesie in die laboratorium eksperimente gebruik om subietale toksisiteitstoetse mee uit te voer. Kadmium- en sinksulfaat is as kontaminante gebruik, en is apart en gemeng toegedien. Die houtluise is geweeg voor die begin van die blootstellings en elke week deur die loop van die blootstellingsperiode van ses weke. Aan die einde van die blootstellingsperiode is hulle gedissekteer om die hepatopankreas te verwyder. Die sink en kadmium inhoude van die hepatopankreas en res van die liggame van die houtluise is bepaal met behulp van atoomabsorpsiespektrofotometrie. Monsters van die hepatopankreas is ook voorberei vir histologiese analise, en metings van die Persentasie Sellulêre Oppervlak (PSO) is gedoen met behulp van beeldanalise. Eksemplare van Porcellionides pruinosus is versamel van 'n gekontamineerde- en 'n ongekontamineerde gebied. Monster van die hepatopankreas en res van die liggaam van P. pruinosus is ook geanaliseer vir kadmium en sink. Histologiese sneë van die hepatopankreas was ook voorberei en geanaliseer, soos in die laboratorium eksperimente. Blootstelling aan kadmium- en sinksulfaat het die massa van P. laevis negatief beïnvloed in die enkelmetaal-eksperimente. Hierdie twee metale het egter mekaar se effekte in die mengseltoksisiteitstoetse "geneutraliseer". Dit dui op 'n antagonistiese interaksie. Toegediende kadmium- en sinksulfaat het gelei tot die akkumulasie van kadmium en sink in the houtluise, veral in die hepatopankreas. In die mengseltoksisiteitstoetse het kadmium en sink mekaar se akkumulasie beïnvloed. Kadmium- en sinksulfaat, apart of as mengsels toegedien, het die struktuur van die hepatopankreas verander, en dit is kwantitatief aangetoon deur die PSO metings. PSO van die hepatopankreas van houtluise is 'n bruikbare algemene biomerker van blootstelling en effek vir kadmium en sink. Dit word voorgestel dat PSO kan dien as 'n algemene biomerker om negatiewe effekte op die groei of massaverandering van houtluise te voorspel wat aan kadmium en sink mengsels blootgestel word. Die bevindinge van die veldondersoek dui daarop dat PSO gepas mag wees om gebruik te word as 'n algemene biomerker om metaal-geïnduseerde stres by houtluise vanaf 'n gekontamineerde gebied te meet.

Knowledge about dispersion is of utmost importance for understanding populations’ reaction to changes in the environment. Expansion of a population range brings with it both spatial sorting and over time, spatial selection. This means that dispersion rates increases over time at the expanding edge. Most studies have so far been performed on continuously expanding populations. This study aims to bring more knowledge about dispersal biology in dynamic systems. I studied dispersal traits in two permanent and two seasonal vegetation habitats of an isopod (Asellus aquaticus), for which differentiation between habitat types has previously been shown. I quantified differences in displacement (dispersal rate) and three morphological traits, head angle (body streamline) and leg of the third and seventh pair of legs. Isopods from the seasonal vegetation had higher displacement rates than animals from permanent vegetation. This inclines that mechanisms driving spatial selection in expanding population ranges also exist in dynamic systems. The more streamlined isopods found in seasonal sites further points towards spatial sorting by dispersion capability. Because no effect of permanence was found on leg length and there was no correlation between streamlining and displacement, the higher dispersion among animals from seasonal habitats most likely derives from behavioral differences.

A subordem Oniscidea abriga os isópodos terrestres, os quais apresentam uma grande riqueza de espécies em diferentes ambientes com características completamente diversas, desde a zona litorânea até ambientes desérticos. No Brasil há uma diversidade de espécies ainda pouco estudada, sendo que a família Philosciidae representa uma grande parte da fauna de isópodos da América do Sul. O presente estudo tem como objetivos descrever uma nova espécie no gênero Benthana para o estado do Rio Grande do Sul, descrever seus estágios de manca e juvenil, assim como caracterizar sua estrutura populacional com respeito aos aspectos reprodutivos e crescimento. Benthana cairensis foi descrita como uma nova espécie de Philosciidae e tem como caracteres diagnósticos a presença de 17 estetascos na antênula, exópodo do pleópodo 1 do macho alongado apresentando um lobo na margem lateral interna. Essa espécie é semelhante a três outras do gênero em relação a presença do lobo, no entanto diferencia-se de todas elas devido às diferenças no número de omatídeos, inserção dos ramos do urópodo e dimorfismo sexual nos pereiópodos dos machos. A fase imatura e indiferenciada sexualmente apresenta três estágios, chamados de mancas. O estágio de Manca I é caracterizado pela simplicidade de suas estruturas e pela sua rápida duração, de aproximadamente 4 horas; apresenta 6 pares de pereiópodos, esses ainda glabros e o aparelho bucal fracamente desenvolvido ainda sem a presença dos dentes pectinados na maxilula, característicos de Benthana. O estágio seguinte, de Manca II, já apresenta o aparelho bucal mais desenvolvido com os dentes pectinados da maxilula e pereiópodos já com o padrão de setas semelhante ao adulto, inclusive a seta “hand-like” do carpo 1, uma autapomorfia do gênero. O último estágio de manca (Manca III) caracteriza-se pela presença do sétimo par de pereiópodos presente dobrado ventralmente sob o corpo do animal. Os estágios de juvenis caracterizam-se pela diferenciação sexual, mas ainda são imaturos sexualmente. Os três primeiros estágios foram descritos para os machos com destaque para o desenvolvimento da protusão do exópodo do pleópodo 1, outra autapomorfia do gênero, o qual só começa a ficar evidente no segundo estágio (JUII) e somente apresenta-se completamente desenvolvido quando o animal atinge aproximadamente 1.0 mm de largura de cefalotórax (LC). O dimorfismo sexual presente nos quatro primeiros pares de pereiópodos dos machos começa a aparecer após os três primeiros estágios de juvenil e está completamente evidente em machos de aproximadamente 1.2 mm de LC. A população de Benthana cairensis do Sítio Cairé caracteriza-se por apresentar uma reprodução contínua durante o ano. As fêmeas investem menos em uma única prole, no entanto são capazes de se reproduzir mais de uma vez ao longo de sua vida. A proporção sexual operacional da população é de 1:1, mostrando que há um equilíbrio no que se refere ao número de machos e fêmeas aptos para reprodução. Os machos vivem menos que as fêmeas e são menores. As fêmeas possuem o corpo maior, o que aumenta a superfície para abrigar a prole o que foi demonstrado pela correlação positiva do tamanho da fêmea com o número de ovos. As características de desenvolvimento de B. cairensis são semelhantes a outras espécies de Philosciidae, apresentando três estágios de mancas. Suas características populacionais, no que se referem a estação reprodutiva e investimento reprodutivo, são semelhantes a outras espécies subtropicais e, como esperado, diferentes de espécies de isópodos que vivem em regiões temperadas. / Terrestrial isopods are included in the suborder Oniscidea which shows a great species richness living at different places showing diverse environmental conditions, occurring from the littoral zone through desert regions. In Brazil there is a diversity that is still poorly studied in which the family Philosciidae represents a great part of South America’s woodlice fauna. The present study aims to describe a new species of the genus Benthana to the state of Rio Grande do Sul, to describe its manca and juvenile stages as well as to characterize its population structure concerning reproductive aspects and growth. Benthana cairensis was described as a new species of Philosciidae and presents the following diagnostic characters: 17 aesthetascs on the antennula and male pleopod 1 exopod elongated with a lobe on the inner lateral margin. This species resembles other three species of the genus concerning the presence of pleopod lobe; however it is differentiated by the number of omatidia, insertion of uropod endopod and exopod and sexual dimorphism on male’s pereiopods. The immature and undifferentiated phase has three stages, called mancas. The Manca I is marked by the simplicity of its appendages and by its queek duration, of about 4 hours; it presents 6 pairs of pereiopods still glabrous and mouth parts weekly developed still without the presence of the pectinate teeth of maxillula, characteristic of Benthana. The next stage, Manca II, already shows the mouth parts a little more complete, presenting the pectinate teeth of maxillula and the pereiopods showing the setae pattern of the adult, including the hand-like seta on carpus 1, an autapomorphy of the genus. The last manca stage (Manca III) is characterized by the presence of the 7th pair of pereiopods folded ventrally on the pereion. The juvenile stages are sexually differentiated, but still immature. The first three stages were described for males, enphatizing the development of dentiform protusion of pleopod exopod 1, another autapomorphy of the genus which begins to be evident only at the second stage (JUII) and it is completely formed when the animal reaches 1.0 mm of cephalothorax width (CW). Sexual dimorphism at the first four male pereiopods beggins to develop after the three juvenile stages and it is completely formed on males of approximatly 1.2 mm of CW. The population of Benthana cairensis at Sítio Cairé is characterized by showing a continnuous reproduction during the year. Females invest less in a single brood, but are able to reproduce more than once in its lifetime. The operational sex ratio of population is 1:1, which shows that there is an equillibrium concerning the number of males and females that are able to reproduce. Males live less than females and are smaller. Females have a bigger body which increases the surface where the brood develops; this was demonstrated by the positive correlation of female body size with the offspring number. The developmental characteristics of B. cairensis are similar to those of the other species of Philosciidae presenting three manca stages. Its population features concerning reproductive season and reproductive effort resembles those of other subtropical species and as expected, is different from species that occur at temperate regions.

Η πραγματική ταξινομική κατάσταση των πληθυσμών του γένους Ligidium, κυρίως αυτών που κατανέμονται στη νότια Ελλάδα, δεν είναι ξεκάθαρη. Αυτό συμβαίνει γιατί η απόληξη του δεύτερου ενδοποδίτη του πλεοποδίου των αρσενικών, που αποτελεί σημαντικό διαγνωστικό χαρακτήρα, ποικίλλει και η εύθραυστη δομή της μπορεί εύκολα να καταστραφεί και κατ’ επέκταση να οδηγήσει σε μια μη ακριβή περιγραφή της κατάστασης αυτού του χαρακτήρα. Οι παλαιότερες μελέτες των φυλογενετικών σχέσεων των ισοπόδων του γένους Ligidium, με χρήση μοριακών δεικτών είναι ολιγάριθμες. Πιο συγκεκριμένα, για τη μελέτη πληθυσμών του γένους Ligidium από τον ελλαδικό χώρο έχει γίνει μόνο μια μελέτη στην οποία χρησιμοποιήθηκε η τεχνική της αλληλούχισης του DNA. Η παρούσα μεταπτυχιακή εργασία αποτελεί την πιο εκτεταμένη φυλογενετική ανάλυση μέσα στο γένος Ligidium. H έρευνα επιλέχθηκε να γίνει σε επίπεδο ατόμων συλλέγοντας πολλούς πληθυσμούς από διαφορετικές περιοχές, οι οποίοι ανήκουν είτε στο ίδιο είτε σε διαφορετικά ποτάμια συστήματα. Συγκεκριμένα χρησιμοποιήθηκαν μοριακοί δείκτες από 26 πληθυσμούς ισοπόδων, οι οποίοι καλύπτουν σχεδόν όλο το φάσμα των ειδών, που ανήκουν στo γένος Ligidium και διαβιούν στον ελλαδικό χώρο. Η πειραματική προσέγγιση περιελάμβανε τον πολλαπλασιασμό αλληλουχιών με τη μέθοδο της αλυσιδωτής αντίδρασης πολυμεράσης (PCR), τον προσδιορισμό της αλληλουχίας τους, και τη στατιστική και φυλογενετική ανάλυσή τους. Οι αλληλουχίες που χρησιμοποιήθηκαν προέρχονται από τους πυρηνικούς γονιδιακούς τόπους ITS1, 5.8s, ITS2 οι οποίοι είναι από τους πιο ευρέως διαδεδομένους μοριακούς δείκτες για μελέτες σε επίπεδο πληθυσμών και ειδών και δεν έχουν προηγουμένως μελετηθεί για άλλα χερσαία ισόποδα. Οι αλληλουχίες επεξεργάστηκαν με τρεις μεθόδους φυλογενετικής ανάλυσης οι οποίες είναι η μέθοδος σύνδεσης γειτόνων (Neighbor-Joining), η Μέθοδος Μέγιστης Φειδωλότητας (Maximum Parsimony) και η Μπεϊεσιανή Συμπερασματολογία (Bayesian Inference). To τελικό σύνολο των στοιχισμένων αλληλουχιών, μετά την αφαίρεση τμημάτων από την αρχή και το τέλος τους, είχε μήκος 614 βάσεων. Σε γενικές γραμμές τα αποτελέσματα που προέκυψαν από τη χρήση των εν λόγω πυρηνικών δεικτών και των τριών φυλογενετικών μεθόδων (BI, MP, NJ), τόσο ως προς τα δέντρα όσο και ως προς τις γενετικές αποστάσεις, δεν θεωρούνται ασφαλή για την εξαγωγή ικανοποιητικών συμπερασμάτων. Επίσης πραγματοποιήθηκε σύγκριση αποτελεσμάτων προηγούμενων μελετών με αυτά που προκύπτουν από τη δική μας έρευνα, καθώς και αξιολόγηση της αξιοπιστίας των μοριακών δεικτών που χρησιμοποιήθηκαν. / Terrestrial isopods (suborder Oniscidea) form a monophyletic group within the crustacean order Isopoda that has conquered almost all terrestrial environments. The family Ligiidae, forming the sister group to all the other Oniscidea (with the possible exception of Tylidae) consists of five genera. The genus Ligidium is the most species-rich genus within Ligiidae and consists of 47 species distributed throughout the northern hemisphere, from western Europe to Japan and North America. The taxonomy of the genus has hitherto been based on a few morphological characters most of which exhibit high intrapopulation variation. As a consequence, the current taxonomy of Ligidium is problematic and the validity of described species cannot be taken for granted. Molecular data for only a few species have been used in broader phylogenetic analyses within terrestrial isopods In the present study we perform the most extensive phylogenetic analysis within the genus Ligidium. We attempt to clarify the taxonomic status of the various populations and try to identify geographical patterns in genealogical affinities that might help us reconstruct the evolutionary history of the respective species. We used three nuclear ribosomal gene segments (ITS1, 5.8s, ITS2) for the phylogenetic analysis of Ligidium populations, which were collected from several locations in Greece, representing almost all species reported from this region. For comparative reasons, we have also included one population from each of the two widespread European species, L. hypnorum, Cuvier, 1792 and L. germanicum, Verhoeff, 1901. Since the taxonomy within the genus is still ambiguous, and because most morphological characters are not dependable for species identification, we chose to perform the analysis at the individual level, sampling several populations from different locations that belong either to the same or to different river systems. Fragments of the three rDNA genes (ITS1, 5.8s, ITS2) were amplified using the polymerase chain reaction (PCR) technique and then individual sequences were determined via automated sequencing. We compare the results which occurred from our study with those of previous ones and we evaluate the plylogenetic utility of the molecular markers that we used. In general the results that came out by the analyses of three following phylogenetic methods Neighbor joining (NJ), Maximum parsimony (MP) and Bayesian Inference (BI), are not considered to be safe for making generalized conclusions.
