Genome duplication drives evolution of species

Many wild and cultivated plants arise through the combination of two species. The genome of these so-called polyploid species often consists of a quadruple set of chromosomes—a double set for each parental species—and ...

Plant diversity in Germany on the decline

In the last 60 years, plant diversity across Germany decreased by an average of 15% in over 70% of the more than 2000 species examined. This most comprehensive analysis of plant data from Germany ever conducted involved researchers ...

Student researchers help discover world's smallest frog

When two Cornell undergraduates and a recent graduate went on a field research trip to Papua New Guinea in 2008, little did they know it would lead to entries in the Guinness Book of World Records and a groundbreaking research ...

Scientists decode watermelon genome

Are juicier, sweeter, more disease-resistant watermelons on the way? An international consortium of more than 60 scientists from the United States, China, and Europe has published the genome sequence of watermelon (Citrullus ...

Natural aphid predators reduce pesticide use

The greater the diversity of crops grown in agricultural landscapes is, the better natural predators of aphids are able to control the pests on wheat fields. This is because a varied landscape provides better living conditions ...

Genome sequencing reveals a new species of bumblebee

While studying genetic diversity in bumblebees in the Rocky Mountains, U.S., researchers from Uppsala University discovered a new species. They named it Bombus incognitus and present their findings in the journal Molecular ...
