Biological surveys reveal unexpectedly high faunal diversity at Nankai Trough methane seeps

Ecosphere, Volume 16, Issue 11, November 2025.
Abstract Cold seeps are chemosynthesis‐based ecosystems powered by microbial primary production that support diverse and specialized faunal assemblages in the deep sea. Despite Nankai Trough in Japan being a geologically active margin hosting numerous seeps, much of the faunal diversity remains undocumented.

Seismic Disturbance, Productivity and Depth Shape Hadal Benthic Habitats and Biodiversity in the Japan, Ryukyu and Izu‐Ogasawara Trenches (Northwest Pacific Ocean)

Journal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim This study characterises benthic habitats and associated biodiversity in three Japanese subduction trenches, and explores the effects of trench‐specific differences in large‐scale seismic events, disturbance and productivity regimes on habitat structure and assemblage composition.

A model‐based assessment of anthropogenic disturbance on lotic macroinvertebrate assemblages

Ecosphere, Volume 16, Issue 10, October 2025.
Abstract Traditionally, the effects of anthropogenic disturbance on biological assemblages are elucidated by comparing an assemblage observed at a site to one that represents a minimally disturbed state. Unfortunately, defining a minimally disturbed state is extremely challenging because of the extent of human disturbance.

Taxon‐specific BLAST percent identity thresholds for identification of unknown sequences using metabarcoding

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2380-2394, October 2025.
Abstract The identification of organisms in environmental samples using metabarcoding relies on factors such as taxonomic assignment methods, genetic markers, reference databases and confidence thresholds for taxonomic assignment. Because lineages evolve at different rates, a global threshold (e.g.

First record of Euborlasia nigrocincta Coe, 1940 (Nemertea: Heteronemertea) from the western Pacific [PDF]

Check List, 2013
The heteronemertean Euborlasia nigrocincta Coe, 1940 was previously known exclusively from the eastern Pacific. A specimen collected on the Izu Peninsula, Honshu, Japan, herein identified as E. nigrocincta, represents the first record of the species from

The evolution of reproduction in Ediacaran–Cambrian metazoans

Biological Reviews, Volume 100, Issue 5, Page 2084-2098, October 2025.
ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

Limited Dispersal of Benthic Environmental DNA From a Subtropical Mesophotic Shelf‐Edge Bank

Environmental DNA, Volume 7, Issue 5, September–October 2025.
We investigated the vertical and horizontal dispersion of eDNA away from an isolated mesophotic coral reef (Bright Bank) in stratified offshore waters. We found that vertical transport of benthic eDNA was limited by water column stratification and that the prevalence of eDNA from benthic invertebrates declined with horizontal distance away from the ...

The contribution of metabolic theory to ecology

Ecological Monographs, Volume 95, Issue 3, August 2025.
Abstract The metabolic theory of ecology (MTE) has been an important strand in ecology for almost a quarter of a century, renewing interest in the importance of body size and the role of energy. The core of the MTE is a hydrodynamic model of the vertebrate cardiovascular system that predicts allometric scaling of metabolic rate with exponents in the ...

Ship hull fouling in the port of Recife, Pernambuco

Brazilian Journal of Oceanography, 2007
Ports of big coastal cities are exposed to exotic species as a consequence of shipping traffic. As the Port of Recife receives an annual average of 491 ships from other regions of Brazil and from all over the world, this work was aimed at knowing which ...

Editorial: diversity of marine meiofauna on the coast of Brazil [PDF]

, 2014
After a first bout of primarily taxonomical effort, meiofauna studies in Brazilian waters remained virtually neglected until the 1990s. At the end of the last century, taxonomical and ecological studies on meiofauna taxa were again published regularly ...
