Living isopods of the suborder Oniscidea (commonly called woodlice) are the only group of Crustacea almost entirely composed of terrestrial forms. Furthermore, woodlice are completely independent from the aquatic environment from which they originally arose. From marine ancestors, woodlice are a key taxon to study the conquest of the land among arthropods because of their interesting gradation of morphological, physiological and behavioral adaptations for terrestriality. However, the origin and… 

The oldest peracarid crustacean reveals a Late Devonian freshwater colonization by isopod relatives

Oxyuropoda is the oldest known Peracarida, and provides evidence that derived peracarids had an incursion into freshwater and terrestrial environments as early as the Famennian, more than 360 million years ago.

A remarkably well-preserved terrestrial isopod (Peracarida: Isopoda: Armadillidiidae) from the upper Oligocene of Hungary, with remarks on the oniscidean taphonomy

A near-perfect preservation of the isopod's cuticular surface indicates their potential to be preserved in marine siliciclastic settings under specific conditions.

An evolutionary timescale for terrestrial isopods and a lack of molecular support for the monophyly of Oniscidea (Crustacea: Isopoda)

The results suggest that the terrestrial environment has been colonized more than once by isopods, and the monophyly of the suborder Oniscidea was not supported in any of the analyses, conflicting with classical views based on morphology.

Fossil evidence of extended brood care in new Miocene Peracarida (Crustacea) from Mexico

The first fossil evidence of extended brood care in Peracarida is described, based on two Oniscidea (Isopoda) gravid females preserved in Miocene Chiapas amber from Mexico.

A new genus of terrestrial isopods (Crustacea: Oniscidea: Armadillidae) in Myanmar amber

ABSTRACT A female terrestrial isopod in amber from Myanmar is described as Palaeoarmadillo microsoma gen. et sp. n. (Isopoda: Oniscidea: armadillidae). Placement in the family Armadillidae is based

Diversity of the Crinocheta (Crustacea, Isopoda, Oniscidea) from Early Miocene Chiapas amber, Mexico

This study represents the first fossil record of the family Detonidae, Olibrinidae, and “Stenoniscidae”, and the oniscidean fauna presented here supports a particularly wet paleoenvironment, under brackish water influence, similar to an estuary.

Aerial and aquatic respiration in littoral Oniscidea (Isopoda) from Southern California, USA

Examination of aerial and aquatic respiration in six species of marine-littoral Oniscidea shows that littoral species tolerate significant periods of immersion, allowing them to withstand habitat inundation during spring high tides, storm swells and, in riparian species, rainstorms and snowmelt.

Genetic evidence against monophyly of Oniscidea implies a need to revise scenarios for the origin of terrestrial isopods

This work employed the highly conserved, nuclear protein-coding genes Sodium-Potassium Pump and Phosphoenolpyruvate Carboxykinase and produced a robust and fully resolved phylogenetic tree that offers strong evidence against the monophyly of Oniscidea.

The cavernicolous Oniscidea (Crustacea: Isopoda) of Portugal

The study of subterranean Oniscidea in Portugal has been neglected for nearly 70 years, but recent investigations have revealed high diversity, and terrestrial isopods are the richest group of cave-adapted animals.



Transition from Water to Land in Amphipod Crustaceans

The Amphipoda have not achieved the terrestrial independence of the Isopoda; they are restricted to a fairly narrow niche and some species have colonized grasslands but in circumstances which are not environmentally very different from leafmold.

Evolutionary adaptation of oniscidean isopods to terrestrial life: Structure, physiology and behavior

This review summarizes the present knowledge of some aspects of the morphology, physiology and behavior as it related to oniscidean adaptation to the terrestrial realm.

The origin of crustaceans: new evidence from the Early Cambrian of China

This new fossil evidence supports the remote ancestry of crustaceans well before the Late Cambrian and shows, along with other fossil data, that a variety of body plans already coexisted among the primitive crustacean stock.

Arthropods in amber from the Triassic Period

It is found that the abundance of amber during the Carnian is globally anomalous for the pre-Cretaceous and may, alternatively, be related to paleoclimate.

Exceptionally preserved crustaceans from western Canada reveal a cryptic Cambrian radiation

Diverse crustacean appendages of Middle and Late Cambrian age from shallow-marine mudstones of the Deadwood Formation in western Canada provide the earliest evidence for crown-group branchiopods and total-group copepods and ostracods, extending the respective ranges of these clades back from the Devonian, Pennsylvanian, and Ordovician.

Global diversity of Isopod crustaceans (Crustacea; Isopoda) in freshwater

  • G. Wilson
  • Environmental Science, Biology
  • 2007
Most species of freshwater isopods species and many genera are narrow range endemics, which ensures that human demand for fresh water will place these isopod crustaceans at an increasing risk of extinction, as has already happened in a few documented cases.

Phylogeny of the Terrestrial Isopoda (Oniscidea): a Review

It is concluded that phylogenetic analyses down to species level need to be conducted in order to construe a robust phylogeny hypothesis for higher oniscidean taxa.

The Silurian-Devonian Fossil Record of the Myriapoda

  • J. Almond
  • Environmental Science, Geography
  • 1985
The oldest recorded terrestrial invertebrates are various small Diplopods (millepedes) from the Lower Old Red Sandstone of Britain which were probably preserved preferentially due to their robust

The ecology of Paleozoic terrestrial arthropods: the fossil evidence

It is postulated that herbivory, defined as predation on living plants, may have been rare in early Paleozoic terrestrial ecosystems, and that most primary productivity of terrestrial arthropods was diverted into higher trophic levels.

The phylogenetic position of the Isopoda in the Peracarida (Crustacea: Malacostraca)

The 18S data alone are inadequate at this phylogenetic level and the combined data provided novel hypotheses that require additional evidence from detailed morphological studies and DNA markers for confi rmation.
