Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

open access: yesWildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

A Tale of Tail Loss: Fine‐Scale Landscape Composition Predicts Caudal Autotomy Along an Urban Gradient in Two Congeneric Lizards

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
Human‐modified landscapes can alter predator–prey interactions, but the spatial scale at which landscape features influence these interactions remains unclear. We examined variation in tail autotomy, a proxy for predation pressure, in two synanthropic lizards across urban gradients.

An integrated novel approach to the environmental health assessment of Bangladesh's coastal ecosystems

open access: yesEnvironmental Challenges
The coastal expanse of Bangladesh, situated along the Bay of Bengal, is a susceptible and low-lying area grappling with multiple environmental challenges. Various physicochemical parameters were employed in the assessment of water quality. The CCME Water

ON THE HYDROGRAPHY OF THE RIVER CLYDE

open access: yesCoastal Engineering Proceedings, 1966
The River Clyde is one of the major industrial rivers of Scotland and the shipbuilding on the banks of its estuary has been famous for centuries. With the increase in the size of the ships being constructed and using the Clyde as a port, steps must be taken to ensure that the Clyde maintains its relative position.

The Plasticity of the Antioxidant Defence System of Coastal Zooplankton Communities

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
In this photo, a copepodite Acartia spp. is represented with Vorticella epiphytes. This photo was taken with the help of a PlanktoScope, which belongs to the Hellenic Centre for Marine Research. Photographer: Andriana Koutsandrea. ABSTRACT Zooplankton are expected to enhance their antioxidant defences and activate stress‐related biomarkers in response ...

Multiscale Bayes Adaptive Threshold Wavelet Transform Geomagnetic Basemap Denoising Taking Residual Constraints into Account

open access: yesSensors
To achieve high-precision geomagnetic matching navigation, a reliable geomagnetic anomaly basemap is essential. However, the accuracy of the geomagnetic anomaly basemap is often compromised by noise data that are inherent in the process of data ...

Tracing methane sources in shallow waters of the North Sea: Biogenic signatures and hydrocarbon transport near abandoned wells

open access: yesLimnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Numerous abandoned wells in the North Sea may provide gas, particularly methane (CH4), migration pathways by penetrating shallow, biogenic gas accumulations. However, related sampling campaigns have been largely contradictory and lack a substantial database. Research cruise MSM98 targeted the abandoned wells B18‐1, DOK 1‐X, B11‐2, THOR and D‐1

Development and Evaluation of the Conjunctive Surface‐Subsurface Process Model Version 3 (CSSPv3) at Global Scale

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract The global terrestrial water and carbon cycles have evolved rapidly during recent decades, particularly in regions with intensive anthropogenic interventions and vulnerable ecohydrological systems. However, current land surface models (LSMs) and global hydrological models (GHMs) often treat natural ecohydrological processes and human water use
