Prioritizing Shark, Ray, and Chimaera Conservation in Rapidly Changing Polar Waters

Global Change Biology, Volume 32, Issue 8, August 2026.
Polar sharks, rays, and chimaeras face growing pressures from changing sea‐ice conditions, expanding fisheries, and limited protection. Our assessment highlights where critical habitats occur and how Important Shark and Ray Areas (ISRAs) can support more targeted conservation and fisheries management across the Arctic and Antarctic.

Improved Constraints on Andean Glaciations From the Lake Titicaca Continental Drilling Record

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Long sedimentary records from tropical lakes provide crucial archives for reconstructing the timing and extent of tropical alpine glaciations, yet robust chronologies beyond the radiocarbon limit (ca. 50 ka) remain scarce. Here, we refine the ca. 350 kyr chronology for Lake Titicaca (Peru‐Bolivia) using radiocarbon dating, optically stimulated
