Revisiting Concepts of Thermal Physiology: Understanding Feedback and Feedforward Control, and Local Temperature Regulation

Acta Physiologica, Volume 241, Issue 7, July 2025.
ABSTRACT Most experts agree that the dominant mechanism through which body temperature is regulated, under a thermal challenge, environmental or metabolic, is negative feedback control. However, some consider negative feedback to be too sluggish to account for the rapid speed of response.

Bridging the Scotia Arc: Climate‐Driven Shifts in Connectivity of the Freshwater Crustacean Branchinecta gaini in Sub‐Antarctic and Antarctic Ecosystems

Diversity and Distributions, Volume 31, Issue 7, July 2025.
ABSTRACT Aim To integrate the historical and contemporary connectivity of Branchinecta gaini (B. gaini), in order to better predict future distribution changes within its fragmented, dynamic and isolated habitat range. Location The study covers 20 locations of freshwater ecosystems across B.

Snow Cover Impacts on Antarctic Sea ice

, 2016
Snow on Antarctic sea ice has tremendous impacts on Albedo, light transmission and sea ice mass balance. Snow Buoys (Nicolaus et al., 2021) measure snow accumu- lation over time with four ultra sonic sensors. Here we present 14 Snow Buoys which were deployed in the Wed- dell Sea since 2013.

Global Sea Ice Coverage from Satellite Data: Annual Cycle and 35-Yr Trends [PDF]

Well-established satellite-derived Arctic and Antarctic sea ice extents are combined to create the global picture of sea ice extents and their changes over the 35-yr period 1979-2013. Results yield a global annual sea ice cycle more in line with the high-

Understanding early ontogeny and whisker growth dynamics of Weddell seal (Leptonychotes weddellii) pups through stable isotope analysis

Marine Mammal Science, Volume 41, Issue 3, July 2025.
Abstract Stable isotope analysis of animal tissues is a valuable tool for understanding foraging ecology, habitat use, and developmental changes throughout an animal's life. Stable isotope values of whisker segments offer long‐term data on mammalian foraging, as whisker growth incorporates isotopic signals from the diet and reflects dietary shifts ...
