A Low‐Order Data‐Driven Model of ENSO Diversity

open access: yesGeophysical Research Letters, Volume 52, Issue 24, 28 December 2025.
Abstract Linear Inverse Models (LIMs) are widely used data‐driven tools for studying El Niño Southern Oscillation (ENSO). However, standard LIMs struggle to simulate the observed asymmetry and diversity of ENSO events. Observations reveal that strong Central Pacific (CP) La Niñas and extreme Eastern Pacific (EP) El Niños occur more frequently than ...

Worldwide Soundscapes: A Synthesis of Passive Acoustic Monitoring Across Realms

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 5, May 2025.
ABSTRACT Aim The urgency for remote, reliable and scalable biodiversity monitoring amidst mounting human pressures on ecosystems has sparked worldwide interest in Passive Acoustic Monitoring (PAM), which can track life underwater and on land. However, we lack a unified methodology to report this sampling effort and a comprehensive overview of PAM ...

Adaptive spatiotemporal management to reduce shark bycatch in tuna fisheries

open access: yesConservation Biology, Volume 38, Issue 4, August 2024.
Abstract Purse‐seine tropical tuna fishing in the eastern tropical Pacific Ocean (EPO) results in the bycatch of several sensitive species groups, including elasmobranchs. Effective ecosystem management balances conservation and resource use and requires considering trade‐offs and synergies.

Vulnerability of Eastern Tropical Pacific chondrichthyan fish to climate change

open access: yesGlobal Change Biology, Volume 30, Issue 7, July 2024.
This assessment identifies sharks' vulnerability to climate change in a data‐poor tropical region and suggests management actions. Abstract Climate change is an environmental emergency threatening species and ecosystems globally. Oceans have absorbed about 90% of anthropogenic heat and 20%–30% of the carbon emissions, resulting in ocean warming ...

Opposing genetic patterns of range shifting temperate and tropical gastropods in an area undergoing tropicalisation

open access: yesJournal of Biogeography, Volume 51, Issue 2, Page 246-262, February 2024.
Abstract Aim The poleward range expansion of tropical species, and range contraction of temperate species (known as tropicalisation) has mainly been studied from an ecological perspective, with little research on its genetic consequences. Here, we used distributional and genetic data to document the consequences of tropicalisation in rocky shore ...
