Piece to the puzzle of baleen whales' evolution

An Otago researcher has added another piece to the puzzle of the evolution of modern baleen whales with a world-first study examining the teeth and enamel of baleen whales' ancestors.

Modern baleen whales have no teeth when adults, instead they use large keratin plates called baleen to filter prey from large volumes of seawater. However, millions...

Bee surveys in newest US national park could aid pollinator studies elsewhere

Declines in native bee populations are widely reported, but can existing data really analyze these trends?

Orchards in natural habitats draw bee diversity, improve apple production

Apple orchards surrounded by agricultural lands are visited by a less diverse collection of bee species than orchards surrounded by natural habitats, according to a new Cornell University-led study, published in the journal Science.

In turn, apple production suffers when fewer, more closely-related species of bees pollinate an orchard. Production improves in orchards surrounded by natural...
