Terrestrial Isopods (Isopoda: Oniscidea) from the Slovenian Karst

open access: yesNatura Sloveniae, 2005
Hand sorting was performed in 28 habitats of the Slovenian Karst during 2004. Twenty-three terrestrial isopod species were identified, two of which proved to be new for the Slovenian fauna, namely Trichoniscus matulici and Armadillidium nasatum ...

Weaponry Investment in the Socially Monogamous Snapping Shrimp Alpheus brasileiro (Decapoda: Alpheidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...

Widespread Wolbachia infection in terrestrial isopods and other crustaceans

open access: yesZooKeys, 2012
Wolbachia bacteria are obligate intracellular alpha-Proteobacteria of arthropods and nematodes. Although widespread among isopod crustaceans, they have seldom been found in non-isopod crustacean species.

Budding speciation, mitochondrial capture and introgression between surface and cave lineages in the Asellus aquaticus species complex

open access: yesCladistics, EarlyView.
Abstract Replicated pairs of ancestral and evolutionarily derived populations provide opportunities to test hypotheses about the deterministic laws of evolution. The Asellus aquaticus species complex is an invertebrate model system with several independent surface‐to‐cave transitions and a complicated and unresolved evolutionary history.

Comparative iTRAQ-based quantitative proteomic analysis of the Chinese grass shrimp (Palaemonetes sinensis) infected with the isopod parasite Tachaea chinensis

open access: yesParasites & Vectors, 2019
Background Although parasitic isopods can negatively affect the reproduction and ingestion of several commercially important crustaceans, little is known regarding the mechanisms that underlie these effects.

Short‐term performance responses of an intertidal fish to sedimentation and warming

open access: yesJournal of Fish Biology, EarlyView.
Abstract Climate change is altering coastal ecosystems by causing environmental fluctuations, such as increases in temperature and turbidity, which pose major implications for fish physiology and behaviour. Increases in temperature affect fish food intake, swimming capacity and oxygen delivery, while increases in turbidity can impair or enhance prey ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

Occurrence and assemblage composition of millipedes (Myriapoda, Diplopoda) and terrestrial isopods (Crustacea, Isopoda, Oniscidea) in urban areas of Switzerland

open access: yesZooKeys, 2012
Terrestrial isopods and millipedes, members of the invertebrate macro-decomposer guild, were collected through pitfall traps in three Swiss cities (Zurich, Lucerne, Lugano).

Do Parasite Effects on Fish Body Condition Depend on Host Size and External Temperature? A Meta‐Analytic Approach

open access: yesJournal of Zoology, EarlyView.
Evaluating relationships between host body condition indices (BCIs) and parasite infections is a common approach for assessing the negative effects of parasites on host health. Researchers generally expect negative correlations between BCIs and infection levels; however, empirical results are often highly variable among host–parasite systems.
