The hidden biology of sponges and ctenophores [PDF]

open access: yesTrends in Ecology & Evolution, 2015
Animal evolution is often presented as a march toward complexity, with different living animal groups each representing grades of organization that arose through the progressive acquisition of complex traits. There are now many reasons to reject this classical hypothesis.

The sex lives of ctenophores: the influence of light, body size, and self-fertilization on the reproductive output of the sea walnut, Mnemiopsis leidyi [PDF]

open access: yesPeerJ, 2016
Ctenophores (comb jellies) are emerging as important animals for investigating fundamental questions across numerous branches of biology (e.g., evodevo, neuroscience and biogeography).

The complete mitochondrial genome of the Ctenophore Beroe cucumis, a mitochondrial genome showing rapid evolutionary rates

open access: yesMitochondrial DNA. Part B. Resources, 2019
We described the complete mitochondrial genome of the Ctenophore Beroe cucumis, which is a circular molecule of 10,487 bp in length. The new mitochondrial genome comprised only 12 genes, making it one of the smallest animals’ mtDNA.

Microbiota Differences of the Comb Jelly Mnemiopsis leidyi in Native and Invasive Sub-Populations

open access: yesFrontiers in Marine Science, 2019
The translocation of non-indigenous species around the world, especially in marine systems, is a matter of concern for biodiversity conservation and ecosystem functioning.

Claims That Anthropogenic Stressors Facilitate Jellyfish Blooms Have Been Amplified Beyond the Available Evidence: A Systematic Review

open access: yesFrontiers in Marine Science, 2018
The perception that anthropogenic stressors cause jellyfish blooms is widespread within the scientific literature and media but robust evidence in support of these claims appears scarce.

Evidence for involvement of Wnt signalling in body polarities, cell proliferation, and the neuro-sensory system in an adult ctenophore. [PDF]

open access: yesPLoS ONE, 2013
Signalling through the Wnt family of secreted proteins originated in a common metazoan ancestor and greatly influenced the evolution of animal body plans. In bilaterians, Wnt signalling plays multiple fundamental roles during embryonic development and in
