It has been shown that the removal of the pituitary body in mammals is generally fatal. Adler, whose work was extended by Allen, Smith, Atwell, and Hogben, has shown that such fatal results do not attend the removal of the amphibian pituitary body. The former investigators were able to destroy the hypophysial rudiment in the frog embryo, and prove that failure to metamorphose is the inevitable consequence of this operation. This work has been strengthened by the observations of Allen and Swingle on the acceleration of the metamorphosis in frog tadpoles by the implantation of the pituitary gland, and they concluded that the anterior portion (pars anterior) was responsible for this curtailment of the larval period. However, Gudernatsch and others found that pituitary feeding does not stimulate metamorphosis in Anura, and Huxley and Hogben obtained similar results with axolotls after feeding several months with anterior lobe. Later, Hogben found that...
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.

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.
