Journal of Water and Climate Change, 2023 Ctenophores are quick responders to coastal environmental changes and play a crucial role in marine food web dynamics. We report the environmental drivers of a ctenophore swarm (Pleurobrachia spp.) and associated ecological changes in estuarine and ...

Zoology: At Last an Exit for Ctenophores [PDF]
Current Biology, 2016 Ctenophores, one of the most basal branches in the tree of life, have been found to have a through-gut, complete with mouth and anus. Basal animals are surprisingly complex and simplification has been rampant in animal evolution.

Alternative neural systems: What is a neuron? (Ctenophores, sponges and placozoans)
Frontiers in Cell and Developmental Biology, 2022 How to make a neuron, a synapse, and a neural circuit? Is there only one ‘design’ for a neural architecture with a universally shared genomic blueprint across species?

Role of SoxE transcription factors in development and disease
Developmental Dynamics, EarlyView.Abstract Sox8, Sox9, and Sox10 arose by multiple rounds of genome duplications from a single SoxE gene in ancestral vertebrates. In this review, we will briefly discuss the molecular structure and function of SoxE transcription factors and their evolutionary origin. We will then discuss their expression, function, and developmental disorders.

Developmental Dynamics, EarlyView.Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.

Not All Ctenophores Are Bioluminescent: Pleurobrachia
The Biological Bulletin, 1995 The traditional view has been that all species of the phylum Ctenophora are capable of producing light. Our inability to elicit luminescence from members of the well-known genus Pleurobrachia, as well as a lack of published documentation, led to an effort to determine whether this genus is truly bioluminescent.

Rethinking Plasticity in Sponges
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.This systematic review critiques the conceptual confusion caused by the indiscriminate use of “plasticity” in Porifera literature, revealing that researchers often overlook genetic variability and fail to distinguish between real‐time environmental responses and natural selection.

Biology, 2020 Phylogenomics, the use of large datasets to examine phylogeny, has revolutionized the study of evolutionary relationships. However, genome-scale data have not been able to resolve all relationships in the tree of life; this could reflect, at least in ...

Speciation of pelagic zooplankton: Invisible boundaries can drive isolation of oceanic ctenophores
Frontiers in Genetics, 2022 The study of evolution and speciation in non-model systems provides us with an opportunity to expand our understanding of biodiversity in nature. Connectivity studies generally focus on species with obvious boundaries to gene flow, but in open-ocean ...

Records of ctenophores from South Africa
PeerJ, 2021 Although ctenophores can be conspicuous components of the plankton in coastal marine ecosystems, only six species have been formally described from around South Africa. Using photographs from local community scientists, we add a further three species ( Cestum veneris, Beroe forskalii ?,
