1. External marking of terrestrial isopods (Isopoda, Oniscidea): efficiency of materials and influence on feeding behavior
Abstract Many monitoring studies use marking techniques to obtain dispersal data on individuals. Marking procedures may influence the vital activities of the terrestrial isopods, such as feeding behavior. The objective of this study was to identify the efficiency of different materials for external marking of woodlice and the influence on their feeding perfo

2. New records of two species of parasitic isopods (Isopoda: Cymothoida: Bopyridae: Athelginae) associated with hermit crabs from the south Atlantic
Abstract Two species of bopyrid isopods from the subfamily Athelginae are recorded from new localities in northeastern Brazil. Parathelges foliatus Markham, 1972 was recorded for the first time from Brazil, in the state of Ceará, parasitising the hermit crab Clibanarius symmetricus (Randall, 1840). Pseudostegias atlantica Lemos de Castro, 1965 is recorded f

3. Coprophagy in detritivores: methodological design for feeding studies in terrestrial isopods (Crustacea, Isopoda, Oniscidea)
ABSTRACT Isopods consume feces in laboratory conditions. We investigated the effects of coprophagy on food consumption and assimilation and on isopod biomass to determine the best methodological design for feeding performance experiments. We used three species of isopods representing different eco-morphological groups and two leaves with different nitrogen c

4. First record of the genus Anuropodione Bourdon, 1967 (Crustacea: Isopoda: Bopyridae) from the South Atlantic
Abstract The family Bopyridae Rafinesque, 1815 is comprised of parasitic isopods with a life cycle involving an intermediate host (copepod) and a definitive host (decapod crustacean). The genus Anuropodione Bourdon, 1967 occurs in all oceans and encompasses five species that are only known as parasites of squat lobsters belonging to the genus Munida Leach, 1

5. Catalogue of terrestrial isopods (Crustacea, Isopoda, Oniscidea) from Brazil: an update with some considerations
Abstract All species of Brazilian terrestrial isopod known up to date, including references and distribution information, are listed. The list comprises 189 valid species, 135 of which are endemic to the country, 22 are recorded also from other countries in the Americas, 20 are introduced, and 12 have circumtropical or pantropical distributions.

6. Notes on two shallow water isopods (Crustacea: Peracarida: Isopoda: Idoteidae) from Kino Bay, Gulf of California, Mexico
Abstract Two species of isopods of the family Idoteidae were collected in the same sample, among sea grasses, in the northern Gulf of California, Mexico. The first species, Synidotea harfordi Benedict, 1897, was more abundant (46 specimens) than the second species, Eusymmerus antennatus Richardson, 1899 (eight specimens). Synidotea harfordi has previously be

7. Rocinela signata (Isopoda: Aegidae) parasitizing the gills of the spotted goatfish Pseudupeneus maculatus (Actinopterygii: Mullidae) in Northeastern Brazil
ABSTRACT Parasitic isopods of fishes usually show wide distribution and low host specificity. This study investigated the occurrence of gill parasites in 120 specimens of spotted goatfish Pseudupeneus maculatus, marine fish of great economic importance for fishery community. The fish were captured monthly in the Coast of Pernambuco State, Northeast Brazil, b

8. Diet composition and feeding habits of the eyespot skate, Atlantoraja cyclophora (Elasmobranchii: Arhynchobatidae), off Uruguay and northern Argentina
ABSTRACT The eyespot skate, Atlantoraja cyclophora, is an endemic species from the southwestern Atlantic, occurring from Rio de Janeiro, Brazil, to northern Patagonia, Argentina. The feeding habits of this species, from off Uruguay and north Argentina, were evaluated using a multiple hypothesis modelling approach. In general, the diet was composed mainly of

9. Three new species of terrestrial isopods (Crustacea, Isopoda, Oniscidea) from Brazilian caves
ABSTRACT A second amphibian species of terrestrial isopods in the genusXangoniscus Campos-Filho, Araujo & Taiti, 2014 and two new species of Trichorhina Budde-Lund, 1908 are described from the Bambuí karst area in the state of Minas Gerais. Xangoniscus odara n. sp. and Trichorhina cipoensis n. sp. were collected in Lapa do Cipó cave, municipality of Itacar

10. Litter traits and palatability to detritivores: a case study across bio-geographical boundaries
The activity of the litter-feeding macrofauna affects litter decomposition rates at the local scale, and their preference for particular litter types is mediated by litter traits. Environmental changes such as invasion by exotic plants may change the characteristics of the litter at a local scale, with consequences to ecosystem processes. Here we evaluated t

11. Detection of Wolbachia (Alphaproteobacteria: rickettsiales) in three species of terrestrial isopods (crustacea: isopoda: oniscidea) in Brazil
Terrestrial isopods are widely infected with Wolbachia. However, little is known about the presence of bacteria in the Neotropical species. The objective of this study was to test the hypothesis of presence of Wolbachia infection in the native species of terrestrial isopods, Atlantoscia floridana and Circoniscus bezzii, and in the introduced species Burmonis

12. First record of Wolbachia in South American terrestrial isopods: prevalence and diversity in two species of Balloniscus (Crustacea, Oniscidea)
Wolbachia are endosymbiotic bacteria that commonly infect arthropods, inducing certain phenotypes in their hosts. So far, no endemic South American species of terrestrial isopods have been investigated for Wolbachia infection. In this work, populations from two species of Balloniscus (B. sellowii and B. glaber) were studied through a diagnostic PCR assay. Fi
