It is well known that various animals in hay infusions appear and disappear in a regular sequence. With a view to ascertain how far the hydrogen-ion concentration of the medium is concerned in this matter, about 20 infusions made with hay and water from different sources have been kept under close observation, their pH and the state of some of the important organisms inhabiting them being examined periodically. The salt content of the medium has a considerable influence on both the hydrogen-ion concentration and on the metabolism of organisms; the culture fluids were titrated in order to determine the “alkali reserve* when the pH determinations were made. Peters (1906 and 1907) and Fine (1912) also examined the “phenolphthalein acidity” and “methyl-orange alkalinity,” or the “titratable acidity” of hay infusions, which, as they themselves recognise, is not a correct expression of the concentration of hydrogen ions with...
Using the reactive scope model to redefine social stress in fishes
In their Review, Katie Gilmour and colleagues redefine the ambiguous concept of social stress by using the reactive scope model as a framework to explain the divergent physiological phenotypes of dominant and subordinate fishes.
JEB grants to support junior faculty
Learn about the grants that we launched in 2023 to support junior faculty from two of our awardees: Erin Leonard, Early-Career Researcher (ECR) Visiting Fellowship recipient, and Pauline Fleischmann, Research Partnership Kickstart Travel Grant recipient. The next deadline to apply is 6 June 2025.
Thirteen-lined ground squirrels survive extraordinarily low blood oxygen
Brynne Duffy and colleagues reveal that thirteen-lined ground squirrels are true hypoxia champions surviving extreme low blood oxygen, down to just 34% oxygen, when they emerge briefly from hibernation.
The Company of Biologists Workshops
For the last 15 years, our publisher, The Company of Biologists, has provided an apt environment to inspire biology and support biologists through our Workshops series. Read about the evolution of the Workshop series and revisit JEB's experience with hosting the first Global South Workshop.
Fast & Fair peer review
Our sister journal Biology Open has recently launched the next phase of their Fast & Fair peer review initiative: offering high-quality peer review within 7 working days. To learn more about BiO’s progress and future plans, read the Editorial by Daniel Gorelick, or visit the Fast & Fair peer review page.
