body size

A handful of high schoolers prompt scientists to develop a new approach for calculating the size of the ancient behemoth.

Researchers disentangle complex connections among vegetation, herbivores, and dung in the South African savanna.

In South Africa, the composition of droppings varies by species’ body sizes, and which animals are found where depends on vegetation density.

As dinosaurs got smaller, their metabolism increased, paving the way for bird evolution.

The animals have a smaller body mass, shorter legs, and longer wings than they did four decades ago.

Researchers recommend greater conservation efforts toward non-mammals and small creatures.

Scientists describe molecular underpinnings of salmon size and of fishes’ ability to navigate murky environments in separate studies.

Ocean animals have been getting bigger over the millennia, according to an analysis of thousands of genera that have plied Earth’s seas since the Cambrian Period.
