Daphnia as a versatile model system in ecology and evolution

open access: yesEvoDevo, 2022
Water fleas of the genus Daphnia have been a model system for hundreds of years and is among the best studied ecological model organisms to date. Daphnia are planktonic crustaceans with a cyclic parthenogenetic life-cycle.

Global Expansion of Ponto‐Caspian Aquatic Invaders: Drivers, Trends and Taxonomic Biases in a Changing World

open access: yesFreshwater Biology, Volume 71, Issue 7, July 2026.
ABSTRACT Biological invasions pose major threats to ecosystems, with aquatic habitats particularly vulnerable due to high connectivity and biodiversity. The Ponto‐Caspian region is widely recognised as a major source of highly invasive non‐native aquatic species, yet a global synthesis of their spatial, taxonomic and temporal invasion patterns has been

Ontogenetic Sequence of Differential Gene Expression in Predator‐Induced Daphnia pulex

open access: yesMolecular Ecology, Volume 35, Issue 13, July 2026.
ABSTRACT In response to predators, many Daphnia species develop inducible morphological defenses. These traits are phenotypically plastic, meaning their production is suppressed in the absence of the predator. While previous studies have identified several neurohumoral factors and candidate genes involved in the development of the defenses, the ...

New Gynandromorph Records for Chirocephalus diaphanus (Branchiopoda, Anostraca, Chirocephalidae)

open access: yesZoodiversity, 2021
We report and describe new Chirocephalus diaphanus gynandromorphs from Tunisia and review the literature of anostracan gynandromorphy and other, possibly associated, somatic aberrations, with comments on their evolutionary significance.

DNA Metabarcoding Reveals Unexpected Predator–Prey–Microbial Dynamics in the Southern Right Whale (Eubalaena australis)

open access: yesMolecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Southern right whale (Eubalaena australis; SRW) populations are recovering from the impacts of commercial whaling, however, recovery has been spatially variable, with strong associations between reproduction and prey availability. The diet of SRWs has not been widely examined, and with SRW foraging shifting away from high‐latitude foraging ...

Discovery and Evaluation of Cadmium‐Adapted Daphnia pulex Genotypes in a Region of Historical Mining Reveals Adaptation Protects the Germline From Cadmium‐Induced Mutations

open access: yesMolecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Exposure to chemical pollutants can alter the rate and genome‐wide distribution of germline mutations. However, studies measuring the effects of chemical exposure on mutation rates and spectra have not considered the ecological and evolutionary backgrounds of the studied genotypes, which could influence the rates and patterns of germline ...

A new species of Lynceus Müller, 1776 from New Caledonia (Crustacea: Branchiopoda: Laevicaudata) from dolines, with remarks on zoogeography

open access: yesEuropean Journal of Taxonomy, 2016
A new species of laevicaudatan branchiopods, Lynceus insularis sp. nov., is described. It is reported from five sinkholes (dolines) in the southern part of New Caledonia. Lynceus insularis sp. nov. is closest to Lynceus species from Australia, but can be

Aquatic Biodiversity of the Pampa Biome: Insights From a Scientometric and Systematic Perspective

open access: yesAustral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT The Pampa biome, in South America, covers parts of Brazil, Uruguay, and Argentina. Its main characteristic is the predominance of grassland areas. The Pampa biome supports high biological diversity and a wide variety of ecosystems. In this study, we provide a comprehensive overview of biodiversity studies focusing on freshwater ecosystems of ...

Evolutionary Systematics of Two Co‐Occurring Paludomid Freshwater Gastropods in Thailand (Cerithioidea: Paludomidae)

open access: yesZoologica Scripta, Volume 55, Issue 2, Page 244-272, March 2026.
ABSTRACT Paludomidae is a diverse family of limnic gastropods in the Cerithioidea, with a distribution range including most of tropical sub‐Saharan Africa, the Nile Valley, Madagascar, the Seychelles, as well as South and Southeast Asia. Its systematics and taxonomy are currently in a state of confusion, with Thailand being inhabited by probably two ...
