Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

open access: yesEcography, Volume 2026, Issue 5, May 2026.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Poleward Shift of Arctic Oceanic CO2 Uptake From Asymmetric Seasonal Changes Under Climate Warming

open access: yesEarth's Future, Volume 14, Issue 5, May 2026.
Abstract The Arctic region plays a disproportionate role in the global carbon cycle by acting as a critical sink for atmospheric CO2. However, how Arctic air‐sea CO2 fluxes will respond to continued warming regarding their spatial and temporal changes remains poorly understood.

DJ4Earth: Differentiable, and Performance‐Portable Earth System Modeling via Program Transformations

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 5, May 2026.
Abstract Differentiable Earth system models (ESMs) enable powerful applications such as sensitivity analysis, gradient‐based calibration, state estimation, boundary flux inversions, uncertainty quantification, and online machine learning. Reverse‐mode automatic differentiation (AD) efficiently provides gradients for such tasks, yet models have rarely ...

Sponges (Porifera: Demospongiae) recorded at the South Shetland Islands and near the Antarctic Peninsula during the Argentinian Summer Antarctic Expedition in 2012

open access: yes, 2021
The Argentinian 2012 Summer Antarctic Expedition took place in the austral summer of 2012. One of its goals was the study of the benthic communities, considering the biodiversity and the distribution of the species around the Antarctic Peninsula and ...

Porifera Associated with Deep-Water Stylasterids (Cnidaria, Hydrozoa): New Species and Records from the Ross Sea (Antarctica)

open access: yesJournal of Marine Science and Engineering
Stylasterid corals are known to be fundamental habitat-formers in both deep and shallow waters. Their tridimensional structure enhances habitat complexity by creating refuges for a variety of organisms and by acting as basibionts for many other ...
