COMMUNITY STRUCTURE OF ISOPODS (ONISCIDEA) AT DIFFERENT ORCHARDS IN ASSIUT, EGYPT [PDF]

open access: yesAssiut University Journal of Multidisciplinary Scientific Research, 2019
Terrestrial isopods provide many important services for the ecosystem such as litter decomposition, nutrient mineralization. The present study aimed to make a survey of the distribution of isopods as leaf litter decomposers; in five different orchards ...

Evidence for the evolution of thermal tolerance, but not desiccation tolerance, in response to hotter, drier city conditions in a cosmopolitan, terrestrial isopod

open access: yesEvolutionary Applications, 2021
Cities are often hotter and drier compared with nearby undeveloped areas, but how organisms respond to these multifarious stressors associated with urban heat islands is largely unknown.

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.

New records of isopods (Crustacea: Peracarida: Isopoda) from the Mesoamerican Reef at Puerto Morelos, Quintana Roo, Mexico [PDF]

open access: yesCheck List, 2016
New distribution records are presented for 19 species of isopods that are recorded for the Mexican Caribbean coast for the first time. The sampling program was conducted in three sites and at three different depths in each site within the Arrecife de ...

More often, less each: Averaging can hide opposing trends in prey occurrence and consumer stomach content

open access: yesJournal of Fish Biology, EarlyView.
Abstract Averages of prey mass in fish stomachs are widely used to track changes in feeding. Yet, a mean over all stomachs is the exact product of two quantities—the frequency of occurrence of a prey and its mean content in the stomachs that contained it—which can move in opposite directions.

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 ...

Eucarid and Peracarid Fauna of the Valencia Seamount, a Deep-Isolated Seamount of the Western Mediterranean: Colonisation Capacity and Historical Changes

open access: yesDiversity
Seamounts can have a strong influence on the distribution and diversity of species, creating an oasis effect that may favour diversification. In order to assess how and to what extent supra- and epibenthic crustaceans can colonise these environments, the

Vicariance and dispersal in the Aegean Archipelago: Molecular phylogeography reveals the origin and divergence times of Hydropsyche (Trichoptera: Hydropsychidae) species

open access: yesJournal of Systematics and Evolution, EarlyView.
Divergence times of Greek Hydropsyche lineages fall mostly within the Pliocene‐Pleistocene, rejecting ancient vicariance. Widespread species show shallow divergences consistent with dispersal, while island endemics exhibit deeper isolation patterns supporting a mixed vicariance‐dispersal model.

Characterizing prevalence and ecological impact of non-native terrestrial isopods (Isopoda, Oniscidea) in tallgrass prairie [PDF]

open access: yes, 2012
Isopods are terrestrial crustaceans whose role and impact in the tallgrass prairie ecosystem remains little explored despite being rather prevalent non-native inhabitants. To better understand this role, we conducted two related studies.

New records and new species of the troglobitic genus Xangoniscus (Crustacea: Isopoda: Styloniscidae)

open access: yesTropical Zoology
New collections from caves in Bahia state, northeastern Brazil, have revealed additional occurrences of Xangoniscus species. These findings have led to the identification of previously unknown, taxonomically significant morphological features for ...
