Antipredatory Strategies of Anurans: An Updated Conceptual Review

Ethology, Volume 132, Issue 9, Page 662-708, September 2026.
To unravel the evolutionary dynamics of predator–prey interactions, we propose an updated, three‐tiered classification of anuran antipredatory strategies. By mapping non‐behavioral, individual, and group defenses across five functional phases, this integrative framework introduces the concept of synergetic coupling.

Ambient noise tomography with a large seismic array

Comptes Rendus. Géoscience, 2011
The emergence of large-scale arrays of seismometers across several continents presents the opportunity to image the Earth's structure at unprecedented resolution, but methods must be developed to exploit the capabilities of these deployments.

Rayleigh waves from correlation of seismic noise in Great Island of Tierra del Fuego, Argentina: Constraints on upper crustal structure

Geodesy and Geodynamics, 2018
In this study, the ambient seismic noise cross-correlation technique is applied to estimate the upper structure of the crust beneath Great Island of Tierra del Fuego (TdF), Argentina, by the analysis of short-period Rayleigh wave group velocities.

An Inflating Upper Mantle Magma Reservoir Beneath the Tip of the Condor Seamount, Azores Revealed by Rapid‐Response Ocean‐Bottom‐Seismometer Data

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Condor Seamount is among the most seismically active regions on the Azores Plateau. In December 2019, an earthquake crisis occurred at the tip of the seamount, which was strongly felt on nearby islands. Two months after the peak of the crisis, we deployed a local network of five ocean‐bottom seismometers around the seamount, recording ...

Detailed Shallow Shear Velocity Structure in the Nankai Trough From Ambient Noise Differential Adjoint Tomography: Implications for Earthquake Generation Mechanisms

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Seismic and aseismic slip has been reported in the Nankai Trough. In this study we apply ambient noise differential adjoint tomography to obtain a high‐resolution S‐wave velocity (Vs) model in the Nankai Trough. The Vs in the very shallow imbricate thrust zone is higher than that on both the seaward and landward sides.

Seismic Tremor as a Precursor to Hydrothermal Explosions Near Mutnovsky Volcano (Kamchatka)

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Mutnovsky Volcano, ∼70 km SW of Petropavlovsk‐Kamchatsky, exhibits persistent degassing, hosts active hydrothermal springs and the Mutnovsky Geothermal Power Plant (MGPP) on its slopes. Using the network covariance matrix approach, we analyzed seismic data recorded in 2023–2024 by 15 seismic stations operating around Mutnovsky Volcano.

Metasurface‐Enabled Active‐Like Passive Radar

Advanced Science, Volume 13, Issue 44, 7 August 2026.
A programmable space‐time‐coding metasurface embeds distinct spatiotemporal tags into ambient wireless signals, allowing passive radar to operate in an active‐like manner. By enabling code‐correlated reconstruction under interference, the approach supports robust real‐time UAV tracking in complex environments and points to intelligent, low‐power ...

Ambient seismic noise tomography of Australian continent [PDF]

Tectonophysics, 2010
Abstract Imaging using information derived from the cross-correlation of the ambient seismic wavefield at different stations has recently become an important tool in seismology. We here present a continent wide study of the Australian crust based on the exploitation of continuous data from extensive portable broad-band deployments across Australia ...
