Homeostasis, a core tenet of life science, describes how organisms keep their internal environment stable despite constant disruptions.
Here's the science behind why some deep sea creatures — such as squids, sharks, sea spiders and worms — get so giant.
News Author: Corporate Communication & Marketing / Korporatiewe Kommunikasie & Bemarking [Alec Basson] Published: 12/07/2021 If we pay closer attention to how birds, rabbits and termites transform their local living spaces in response to varying climate conditions, we could become much better at predicting what impact climate change will have on them in the future. This is according to a group of researchers* from the Universities of Montana and Wyoming in the United States, the University of Tours in France and Stellenbosch University (SU) in South Africa. They examined how animals' ability ...
For their new study in the Proceedings of the National Academy of Sciences, the researchers developed a new model to determine how water temperature, oxygen availability, body size, and activity affect metabolic demand for oxygen in fish. The researchers based their model on physicochemical principles that look at oxygen consumption and diffusion at the gill surface in relation to water temperature and body size. They compared predictions against actual measurements from over 200 fish species where oxygen consumption rates were measured at different water temperatures and across individuals ...
