The cavernicolous Oniscidea (Crustacea: Isopoda) of Portugal [PDF]

open access: yesEuropean Journal of Taxonomy, 2015
The study of subterranean Oniscidea in Portugal has been neglected for nearly 70 years, but recent investigations have revealed high diversity. All the terrestrial isopods from caves of mainland Portugal, including data from the literature and new material, are listed, revealing new biodiversity patterns.

Data on the terrestrial Isopoda fauna of the Alsó-hegy, Aggtelek National Park, Hungary [PDF]

open access: yes, 2008
Field surveys in dolines of Alsó-hegy, Aggtelek Karst (Hungary) yielded 10 terrestrial isopod species. Despite of the relatively low species richness, we would like to emphasize the high naturalness of the area indicated by the presence of endemic and

Does the Cave Environment Limit Functional Diversity? Rethinking Patterns in Oniscidea Assemblages From a Neotropical Karst

open access: yesBiotropica, Volume 58, Issue 1, January 2026.
Cave habitats strongly filter functional traits, constraining the diversity of terrestrial isopod communities along the epigean–hypogean gradient. Functional turnover decreases while richness differences increase in hypogean systems, reflecting uneven occupation of trait space rather than simple trait replacement.

The genus Ctenorillo Verhoeff, 1942 (Oniscidea, Armadillidae) from Colombia: new records, new species, and conservation comments

open access: yesTropical Zoology, 2023
The Armadillidae are the most diverse family within the Oniscidea, widely distributed around the world. To date, only seven species of the family are known from Colombia. After the examination of a collection from the Colombian departments of Atlántico,

Nitrogen enrichment promotes isopods through reduced carbon and nitrogen stoichiometric mismatch with understorey plants

open access: yesFunctional Ecology, Volume 39, Issue 11, Page 3225-3237, November 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract As key detritivores and fungal grazers, terrestrial isopods (Isopoda: Oniscidea) play crucial roles in mediating ecosystem processes. Although nitrogen enrichment represents a major global change driver known to modify soil food webs, its long‐term effects on the ...

Constrained body shape among highly genetically divergent allopatric lineages of the supralittoral isopod Ligia occidentalis (Oniscidea)

open access: yesEcology and Evolution, Volume 6, Issue 5, Page 1537-1554, March 2016., 2016
The rocky supralittoral isopod Ligia occidentalis sensu lato has a broad distribution in the eastern Pacific, where multiple allopatric genetically divergent lineages occur, which are exposed to marked environmental differences. Using geometric morphometrics, we detected statistically significant differences in body shape among highly divergent ...

A new record of the species Haplophthalmus movilae Gruia & Giurginca, 1998 (Isopoda, Oniscidea, Trichoniscidae, Haplophthalminae)

open access: yesTravaux de l'Institut de Speologie Emile Racovitza
The species Haplophthalmus movilae, long considered as restricted to the sulfidic groundwater ecosystem of Movile Cave was collected from an endogeous location outside the cave.

The first troglobitic terrestrial isopod (Isopoda, Oniscidea) from Peru

open access: yesNauplius, 2023
The present work aims to describe the first troglobitic terrestrial isopod (Oniscidea) from Peru. Caecopactes chullachaqui sp. nov. is described from Cueva de Palestina, Department of San Martín.

Student News [PDF]

open access: yes, 2018
Calyptrates are a megadiverse, actively radiating, group of dipterans, which are widely spread and abundant in nearly all terrestrial environments. Despite huge diversity and economic importance, their phylogeny is far from resolved.
