The first-generation Daphnia magna linkage map [PDF]
BMC Genomics, 2010 Daphnia magna is a well-established model species in ecotoxicology, ecology and evolution. Several new genomics tools are presently under development for this species; among them, a linkage map is a first requirement for estimating the genetic background of phenotypic traits in quantitative trait loci (QTL) studies and is also very useful in assembling

Novel approaches to toxicity testing in Daphnia magna [PDF]
, 2010 Current regulatory risk assessment strategies have several limitations, such as linking subcellular changes to higher-level biological effects, and an improved knowledge-based approach is needed.

An SNP-based second-generation genetic map of Daphnia magna and its application to QTL analysis of phenotypic traits [PDF]
, 2014 Background: Although Daphnia is increasingly recognized as a model for ecological genomics and biomedical research, there is, as of yet, no high-resolution genetic map for the genus.

Comparative toxicity assessment of nanosilver on three Daphnia species in acute, chronic and multi-generation experiments [PDF]
, 2013 The antibacterial properties of nanosilver have led to a versatile application spectrum including medical purposes and personal care products. However, the increasing use of nanosilver has raised concerns about its environmental impacts.

Successfully resisting a pathogen is rarely costly in
, 2010 Background A central hypothesis in the evolutionary ecology of parasitism is that trade-offs exist between resistance to parasites and other fitness components such as fecundity, growth, survival, and predator avoidance, or resistance to other parasites.

Annotation of the Daphnia magna nuclear receptors: Comparison to Daphnia pulex [PDF]
Gene, 2014 Most nuclear receptors (NRs) are ligand-dependent transcription factors crucial in homeostatic physiological responses or environmental responses. We annotated the Daphnia magna NRs and compared them to Daphnia pulex and other species, primarily through phylogenetic analysis. Daphnia species contain 26 NRs spanning all seven gene subfamilies.

Interspecific differences between D. pulex and D. magna in tolerance to cyanobacteria with protease inhibitors. [PDF]
PLoS ONE, 2013 It is known that cyanobacteria negatively affect herbivores due to their production of toxins such as protease inhibitors. In the present study we investigated potential interspecific differences between two major herbivores, Daphnia magna and Daphnia ...

Host specificity and genetics of host resistance in the "Daphnia-Pasteuria" host-parasite system [PDF]
, 2012 Antagonistic coevolution plays an important role in a large number of evolutionary and ecological phenomena. Furthermore, according to the Red Queen Theory coevolution between hosts and their parasites may explain the maintenance of sexual reproduction ...

Live observation of the oviposition process in Daphnia magna.
PLoS ONE, 2019 In favorable conditions, Daphnia magna undergoes parthenogenesis to increase progeny production in a short time. However, in unfavorable conditions, Daphnia undergoes sexual reproduction instead and produces resting eggs.

Cytological and molecular description of Hamiltosporidium tvaerminnensis gen. et sp. nov., a microsporidian parasite of Daphnia magna, and establishment of Hamiltosporidium magnivora comb. nov. [PDF]
, 2010 We describe the new microsporidium Hamiltosporidium tvaerminnensis gen. et sp. nov. with an emphasis on its ultrastructural characteristics and phylogenetic position as inferred from the sequence data of SSU rDNA, alpha-and beta-tubulin.
