Squash bees flourish in response to agricultural intensification

While pollinator populations of many species have plummeted worldwide, one bee species is blowing up the map with its rapid population expansion. The key to this insect's success? Its passion for pumpkins, zucchinis, and ...

Conservation of Nara Park deer results in unique genetic lineage

The existing wildlife of a region is heavily shaped over generations by environmental factors and human activity. Activities like urbanization and hunting are known to reduce wildlife populations. However, some cultural or ...

Neutron experiments reveal what maintains good function in bones

Around 500 million years ago, early vertebrates in the seas became fish, adopting an inner skeleton and a flexible spine based on a nanocomposite of fibers and mineral, known as bone material. This "invention" of evolution ...

Which population structures maximize evolutionary fitness?

Scientists at the Max Planck Institute in Plön have shown that population structures that enhance the effect of selection do not necessarily also lead to higher fitness. Instead, it is crucial for maximizing fitness that ...

Striking lane-like patterns found in bacteria populations

It's well understood that populations of species don't distribute at random. Rather, as populations grow, individuals are organized around barriers in the landscape. This organization can be seen in, for example, the growth ...
