Diversity and Potential Endemism of New Zealand Freshwater Rotifers Revealed Using Mitochondrial DNA Barcodes

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 1, March 2026.
Rotifers perform key functions in aquatic food webs and respond to environmental changes, thus providing sensitive indicators of water quality. However, rotifers are small, highly diverse, and difficult to identify for those lacking expertise. Monogononta are the largest taxonomic class of rotifers with over 1500 species described globally, and around ...

Zooplankton Assemblage Structure of the Lower Mississippi River and Floodplain in Relation to Site Hydrological Connection

open access: yesRiver Research and Applications, Volume 42, Issue 2, Page 400-414, February 2026.
ABSTRACT The pattern of flow or hydrological connection between a river's main channel and its floodplain can vary seasonally and spatially in frequency, duration, direction, and magnitude. Such variation is expected to promote habitat and biotic diversity.

The Effect of Temperature on Reproductive Characteristics of an Asexually Reproducing Rotifer (Class Bdelloidea) [PDF]

open access: yes, 1997
Most organisms exhibit sexual reproduction. Rotifers of the class Bdelloidea, however, seem to be a notable exception to this pattern. No male bdelloid individuals have ever been observed, and females apparently reproduce entirely through parthenogenesis.

Phylogenomics of unusual histone H2A Variants in Bdelloid rotifers. [PDF]

open access: yesPLoS Genetics, 2009
Rotifers of Class Bdelloidea are remarkable in having evolved for millions of years, apparently without males and meiosis. In addition, they are unusually resistant to desiccation and ionizing radiation and are able to repair hundreds of radiation ...

Biodiversity in mountain soils above the treeline

open access: yesBiological Reviews, Volume 100, Issue 5, Page 1877-1949, October 2025.
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...
