Diazotroph‐Driven 210Po Scavenging Reveals a Potential Radiotracer for Marine Nitrogen Fixation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The role of phytoplankton, particularly diazotrophs, in affecting in situ 210Po scavenging has been little investigated. Here, we first report an enhanced 210Po deficit in a cyclonic eddy core relative to its edge in the subtropical Pacific, coinciding with an elevated integrated nitrogen fixation rate (NFR).

Genetic Diversification in a New Guinean Frog Genus (Mantophryne, Microhylidae) was Driven by Ancient Tectonic Activity and Climate Reorganisation

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Our dated phylogeny and biogeographic analysis of Mantophryne, a microhylid frog genus endemic to New Guinea, revealed origins in the East Papuan Composite Terrane (EPCT) in the late Pliocene. Dispersal and diversification out from the EPCT was driven by tectonic activity and climate reorganisation, creating habitat corridors and isolations in the Late

Hemisphere‐Level Comparison of Climate‐Driven Humpback Whale Breeding Migrations to the Eastern Pacific Off Costa Rica

Ecology and Evolution, Volume 16, Issue 5, May 2026.
This study analyzed humpback whale occurrence off the Pacific coast of Costa Rica from 2001 to 2023, focusing on the Central America and Southeast Pacific Distinct Population Segments, using long‐term sightings and Bayesian time‐series and habitat models.

Trends in marine species distribution models: a review of methodological advances and future challenges

Ecography, Volume 2026, Issue 5, May 2026.
Correlative species distribution models (SDMs) are quantitative tools in biogeography and macroecology. Building upon the ecological niche concept, they correlate environmental covariates to species presence to model habitat suitability and predict species distributions.

The Deep‐Sea Preyscapes of Mammalian Top Predators

Environmental DNA, Volume 8, Issue 3, May–June 2026.
Deep‐sea predator foraging is shaped by prey richness, accessibility, and density. Using eDNA and acoustics, we mapped fish and cephalopod communities across inshore‐offshore gradients around the Azores in foraging habitats of three co‐occurring deep‐diving toothed whales.

Fault‐Mediated Groundwater‐Surface Water Mixing Amplifies Hydrochemical/Hydrological Dynamics in a Semi‐Arid Volcanic Lake Basin

Hydrological Processes, Volume 40, Issue 5, May 2026.
Isotopes data help to understand the GW‐SW connectivity, the recharge elevations, and evaporation in a volcanic lake basin. ABSTRACT Understanding groundwater (GW) to surface water (SW) connectivity (i.e., the exchange of water and solutes between aquifers and surface bodies) is increasingly important under changing climate conditions, where ...
