DNA Metabarcoding Reveals Unexpected Predator-Prey-Microbial Dynamics in the Southern Right Whale (Eubalaena australis). [PDF]
Mol EcolABSTRACT 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 ...

Comparative Analysis of Convergent Jellyfish Eyes Reveals Extensive Differences in Expression of Vision-Related Genes. [PDF]
Ecol EvolEyes have evolved in many different lineages, including several times within jellyfish, yet the relative contributions of shared and lineage‐specific genes to convergent eyes are not known. We find that three long‐diverged species of jellyfish have mostly divergent patterns of gene expression in their eye‐bearing tissues, suggesting a major role for ...

Occurrence and Habitat Characteristics of Aurelia sp. Polyps in a High-Latitude Fjord
Frontiers in Marine Science, 2021 Causes and consequences of jellyfish bloom formation are subject to controversial discussions worldwide. While medusae have been studied to a broader extent, the knowledge on polyp stages of scyphozoans is limited thus hampering reliable prediction of ...

Developmental Fates of Progenitor/Undifferentiated Cells With Histone Trimethylation Tags in the Stony Coral, Acropora tenuis. [PDF]
Dev Growth DifferIn the stony coral, Acropora tenuis, embryos and larvae have progenitor/undifferentiated cells. Undifferentiated‐like cells differentiate into the pharyngeal stomodeum at an early larval stage, and nerve progenitors possess the dual potential to differentiate into nerve cells and vacuolated hyaline cells, depending on the oral‐aboral position ...

Population Structures and Levels of Connectivity for Scyphozoan and Cubozoan Jellyfish
Diversity, 2021 Understanding the hierarchy of populations from the scale of metapopulations to mesopopulations and member local populations is fundamental to understanding the population dynamics of any species.

Embryonic development of the moon jellyfish Aurelia aurita (Cnidaria, Scyphozoa): another variant on the theme of invagination [PDF]
PeerJ, 2022 Background Aurelia aurita (Scyphozoa, Cnidaria) is an emblematic species of the jellyfish. Currently, it is an emerging model of Evo-Devo for studying evolution and molecular regulation of metazoans’ complex life cycle, early development, and cell ...

The International Journal of Developmental Biology, 2007 Polyps of Scyphozoa have a cup-shaped body. At one end is the mouth opening surrounded by tentacles, at the other end is an attachment disc. The body wall consists of two tissue layers, the ectoderm and the endoderm, which are separated by an extracellular matrix, the mesoglea.
