Increasing abundance of bowhead whales in West Greenland.

abstract：:Learning is an important form of phenotypic plasticity that allows organisms to adjust their behaviour to the environment. An individual's learning performance can be affected by its mother's environment. For example, mothers exposed to stressors, such as restraint and forced swimming, often produce offspring with imp...

Using flowers, fruits/cones and seeds from a well-dated (23 Ma) Miocene Lagerstätte in New Zealand, we show that across 23 families and 30 genera of forest angiosperms and conifers, reproductive features have remained constant for...
