Length‐Based Spawning Potential Ratio Assessment of Key Species From a Remote Recreational Fishery at Diego Garcia, Indian Ocean

Fisheries Management and Ecology, EarlyView.
ABSTRACT Recreational fisheries in remote regions often operate under limited regulation and data availability, presenting challenges for sustainable management. Diego Garcia, located within the Chagos Marine Protected Area, hosts a unique recreational reef fishery embedded within a highly protected environment. We assessed the stock status of five key

Tooth morphology of deep‐water catsharks of the genus Apristurus (Chondrichthyes: Pentanchidae) in the North Atlantic Ocean

Journal of Fish Biology, EarlyView.
Abstract The deep‐water catshark family (Pentanchidae) is the most species‐rich family among extant shark lineages. Within this family, the genus Apristurus is the largest, comprising small, deep‐sea species characterised by elongated bodies and dorso‐ventrally compressed snouts. Five Apristurus species are currently recognised from the North Atlantic,

First insights into oceanic manta ray movements in Japan using satellite telemetry

Journal of Fish Biology, EarlyView.
Abstract Japanese waters represent the northern distributional limit of the western Pacific distribution of the oceanic manta ray (Mobula birostris), yet movement ecology in this region remains poorly understood. We report movements of the first satellite‐tagged individual in Japan.

Seamounts – characteristics, formation, mineral deposits and biodiversity

Geologica Acta, 2012
Seamounts represent crust-mantle activities and are areas of petrological deviations, biodiversity, seismicity and hydrothermal events. An estimated ~50 million tons/year of basalts are required to produce seamounts suggesting intense oceanic volcanism.

Geographical distribution and driving force of micro-eukaryotes in the seamount sediments along the island arc of the Yap and Mariana trenches

Microbiology Spectrum, 2023
The specific topographic characteristics and complex hydrodynamics of seamounts could directly or indirectly affect the distribution and trophic status of microbes. However, little is known about the distribution patterns and associated driving forces of

Kogia Records in Brazilian Equatorial and Southwestern Atlantic Oceans

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales are cryptic cetaceans characterized by inconspicuous surfacing behavior, small group sizes, and deep‐diving habits, making visual detection particularly challenging. Here, we present the first broad‐scale passive acoustic monitoring (PAM) assessment of Kogia spp.

The 2025 Kamchatka Earthquake and Tsunami: Cascading Impacts and Risks to Japan

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2837-2854, September 2026.
ABSTRACT On July 29th, 2025, a large earthquake (Mw 8.8) occurred near the Kamchatka Peninsula. This event caused a tsunami that reached Japan's Pacific coast, even though the source was far away. In this study, we analyze the characteristics of earthquakes and tsunamis and discuss how they relate to the recurrence possibility and risk in Japan.

Monogenetic Near‐Island Seamounts in the Galápagos Archipelago

Geochemistry, Geophysics, Geosystems, 2020
Rarely have small seamounts on the flanks of hotspot derived ocean‐island volcanoes been the targets of sampling, due to sparse high‐resolution mapping near ocean islands.
