Coral Reefs in the Indonesian Seas Threatened by Heat and Cold Stress

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Heat accumulation and rising sea surface temperatures (SST) are currently major stressors for coral reefs worldwide. Coral reefs are also impacted by cool SST anomalies, although the dynamics of cold stress events are less well understood. Here, we estimate coral bleaching metrics in the Indonesian Seas using a high‐spatial‐temporal‐resolution

Ecology of Thioploca spp.: Nitrate and sulfur storage in relation to chemical microgradients and influence of Thioploca spp. on the sedimentary nitrogen cycle

, 2001
Microsensors, including a recently developed NO3 − biosensor, were applied to measure O2 and NO3 − profiles in marine sediments from the upwelling area off central Chile and to investigate the influence of Thioploca spp.

Mixing at the Margins Drives Nitrate Delivery During Downwelling

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Wind‐driven coastal upwelling delivers nutrients to the surface waters and enhances primary productivity. In contrast, downwelling transports nutrient‐depleted water away from the surface and is usually presumed to decrease primary production. Here, we show that processes during downwelling can actually pump nutrients into previously nutrient ...

Shallow Eastern Indian Ocean Thermocline Hinders ENSO Teleconnection to Southern Africa

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Rainfall peaks during austral summer in southern Africa, where most countries are vulnerable to hydroclimate extremes induced by El Niño‐Southern Oscillation (ENSO). Climate models have struggled to simulate the ENSO impact pattern, with excessive southwestward contraction of El Niño‐induced dry anomalies alongside wet anomalies extending too ...

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.
