An investigation into the diet of elephant fish (Callorhinchus milii) in the waters of Aotearoa/New Zealand

Journal of Fish Biology, EarlyView.
Abstract Chondrichthyans (sharks, rays and chimaeras) are increasingly understood to be an important part of ocean ecosystems, but their ecological role is unclear. Callorhinchus milii (elephant fish) is a chimaera species endemic to Aotearoa/New Zealand and southern Australian waters.

Morphological Characterization and Complete Mitochondrial Genome of a New Epizoic Hexamerous Brittle Star Gymnolophus sexradia sp. Nov

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study describes a new hexamerous epizoic brittle star species, Gymnolophus sexradia sp. nov., from the South China Sea, which lives on crinoid hosts and exhibits a six‐armed body plan possibly indicating fissiparity. Its vertebral and arm plate structures enhance horizontal flexibility for grasping the host, and phylogenetic analysis based on ...

Contrasting cryptofaunal responses to seabird nutrient inputs illuminate coral reef productivity pathways

Ecology, Volume 107, Issue 7, July 2026.
Abstract Nutrients moving across ecosystems can propagate through food webs via distinct trophic pathways. Their integration into food webs is often mediated by small, abundant taxa that channel subsidies from primary producers to higher trophic levels.

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats

Limnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping

Remote Sensing in Ecology and Conservation, Volume 12, Issue 3, Page 444-461, June 2026.
Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Evaluating and Advancing the Use of Shore‐Based Observers for Scientific Sampling and Catch Verification in High‐Volume Fisheries

Fisheries Management and Ecology, Volume 33, Issue 3, Page 612-629, June 2026.
ABSTRACT Shore‐based observers are increasingly being used in place of at‐sea observers to monitor and sample commercial fisheries catch. However, few evaluations assess whether these programs meet their stated goals or how to optimize them, and industry data are rarely tested for accuracy despite serving as the foundation for catch accounting. Using a

The complete mitochondrial genome of a deep sea ophiuroid of the genus Amphiura (Ophiuroidea: Amphiuridae)

Mitochondrial DNA. Part B. Resources, 2019
Amphiura is a widely distributed genus of Ophiuroidea from various environment, play an important role in evolution. Here, we reported a complete mitochondrial genome of Amphiura sp. which was collected from a deep sea seamount in the West Pacific.
