Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

An endogenous green fluorescent protein–photoprotein pair in Clytia hemisphaerica eggs shows co-targeting to mitochondria and efficient bioluminescence energy transfer [PDF]

open access: yesOpen Biology, 2014
Green fluorescent proteins (GFPs) and calcium-activated photoproteins of the aequorin/clytin family, now widely used as research tools, were originally isolated from the hydrozoan jellyfish Aequora victoria.

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

An evolutionary genomics view on neuropeptide genes in Hydrozoa and Endocnidozoa (Myxozoa)

open access: yesBMC Genomics, 2021
Background The animal phylum Cnidaria consists of six classes or subphyla: Hydrozoa, Scyphozoa, Cubozoa, Staurozoa, Anthozoa, and Endocnidozoa. Cnidarians have an early evolutionary origin, diverging before the emergence of the Bilateria.

Rising Connectivity, Shifting Hubs: The Evolving Network and Governance Challenges of Global Wild‐Sourced Trade

open access: yesAnimal Conservation, EarlyView.
Wild‐sourced wildlife trade is not only increasing in volume but also changing in network structure. Using three decades of CITES trade records, we found that the wild‐sourced wildlife trade has become increasingly connected and taxonomically uneven, with Anthozoa contributing a growing share.
