Have you ever gone for a walk and noticed that the landscape has changed? Changes in plant species are easy to spot between, for example, a meadow and a forest. The transition area of biomes is called an ecotone which...
Pinyon pine hybridization is widely acknowledged, but the frequency of and contributors to such interspecific mating remain largely unstudied. Pinus quadrifolia has three to four needles per fascicle, suggesting it is a...
The Qinghai-Tibetan Plateau (QTP) is extremely rich in species, but why? One recent explanation is the mountain‐geobiodiversity hypothesis (MGH) by Mosbrugger et al. The argument is that biodoversity happens when you...
We’re familiar with seeing insects flit from one flower to the next, carrying pollen as they do so. What happens when they carry pollen to the wrong flower species? Sachiko Nishida and colleagues have been testing some...
Polyploidy (whole genome duplication) is one of the most important processes in plant evolution. Most land plants have an evolutionary history that includes multiple polyploidization events. Allopolyploidy...
