From Lotic to Lentic: SWOT Characterizes Seasonal Hydrodynamics in the Lake‐River Continuum

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The interface between rivers and lakes forms a unique hydraulic continuum, in which lotic and lentic regimes dynamically interact and transition between each other. A common expression of this lake‐river continuum (LARIC) is reservoir backwater, where water surface gradually rises from the reservoir pool upstream to the free‐flowing river ...

A new approach to satellite-derived bathymetry: the use of NDWI and ANN with bathymetry sections for reservoir mapping

Boletim de Ciências Geodésicas
Abstract: Mapping the submerged bottom is a hampered task when traditional vessels are inserted in shallow places that pose a danger to navigation. In this sense, current research has sought optical remote sensing to obtain bathymetry estimates in larger locations in less time.

One Assay to Rule Them All: Development of a Global Environmental DNA Tool to Support Range‐Wide Surveys of an Imperiled Sawfish and Its Application in the Eastern Tropical Pacific

Ecology and Evolution, Volume 16, Issue 6, June 2026.
To identify promising locations where Largetooth Sawfish, Pristis pristis, may persist, a novel species‐specific Droplet Digital PCR (ddPCR) assay was designed capable of detecting a single copy of DNA, with in silico and in vitro validation experiments indicating functionality across the species' historical range.

The Mascarene Archipelago, a Data‐Poor Region for Mobulid Rays: First Records, Seasonal Patterns and Conservation Implications

Ecology and Evolution, Volume 16, Issue 6, June 2026.
This study provides the first synthesis of mobulid ray occurrence in the Mascarene Archipelago, using citizen science data to document species diversity, spatial distribution and seasonal patterns, including the first confirmed records of Mobula birostris in Mauritius and M. tarapacana in La Réunion. It reveals that multiple species utilise the region,

Environmental and Protection Effects of Shark‐Companion Associations Across Three Ocean Basins

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Companion species frequently associate with large marine hosts, yet the ecological drivers of these relationships remain poorly understood. Using a global dataset of midwater BRUVS deployments, we modelled the presence and abundance of shark‐companion associations across seven shark species and three ocean basins.

Expected applications of Satellite Derived Bathymetry to hydrographic services.

, 2017
The authors have been developing the technique of Satellite Derived Bathymetry（ SDB） and have created trial SDBs at various waters around Japan. The trial SDB around Hateruma Island, Okinawa Pref., penetrates down to 24 m, which infers the maximum ...

Whole System Ecohydrological Change Following Natural Flood Management and a Five‐Year Beaver Reintroduction Trial

Ecohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Once‐common beavers have been absent from the British landscape for centuries, but wild beaver populations have returned in recent years as part of reintroduction schemes, including releases into monitored enclosures. In North Yorkshire, such a release of Eurasian beavers took place in 2019.

GRDL: A New Global Reservoir Area‐Storage‐Depth Data Set Derived Through Deep Learning‐Based Bathymetry Reconstruction

Water Resources Research
Reservoirs play a critical role in the global water cycle by regulating the flow of water from the environment into human systems. Accurate estimation of the area‐storage‐depth relationships for global reservoirs is essential for effective hydrological ...
