Experimental Physiology, EarlyView.Abstract High‐resolution movement data from Cuvier's beaked, or goose‐beaked whale (Ziphius cavirostris, hereafter Ziphius, n = 8) tag deployments (4.1–19.2 days) were used to estimate blood and tissue O2 and CO2 levels. Acceleration and magnetometry data were used to estimate the locomotion cost (LC) from the relationship between activity and the O2 ...

Multi-Base Active Location Based on Cross-Domain Information Synchronization
水下无人系统学报The information synchronization problem is one of the difficulties in the application of multi-base active sonar systems. In existing research and application, it is usually assumed that the receiving station knows the pulse transmission time of the ...

Transactions in GIS, Volume 29, Issue 7, November 2025.ABSTRACT The Southern Resident killer whales (SRKW) are an endangered species that occupy marine environments on the west coast of North America, including the Salish Sea. Representing marine species in this environment can be achieved by multidimensional space–time simulation modeling that provides more information about locations and behaviors for ...

Ecological Solutions and Evidence, Volume 6, Issue 4, October–December 2025.Recreational freshwater anglers in Hungary were surveyed to assess the scale, causes, and impacts of abandoned, lost or discarded fishing gear (ALDFG). Based on 416 responses, we estimate that 7–11 million items of fishing gear are lost annually, amounting to over 40,000 tons by 2050 if current trends continue.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 10, October 2025.ABSTRACT Turtles are among the world's most endangered vertebrates, with habitat destruction and predation as major contributors to population declines. Hatchling release programmes are increasingly implemented to enhance juvenile recruitment in threatened populations, but limited understanding of hatchling ecology impedes evidence‐based management.
