Humidity changes in dead fern fronds drives unique timing of spore dispersal in a widespread fern species

November 30, 2021

The sensitive fern – named due to its sensitivity to drought and frost – is a widespread species found throughout eastern North America and eastern Asia. It is a dimorphic plant because it has two distinct types of leaves – one for photosynthesis and one for reproduction. While most fern species in temperate regions produce and disperse their spores in the summer, the sensitive fern has an atypical timing of spore dispersal. In the early summer they produce heavily modified spore-bearing fronds (or leaves) with leaflets tightly enveloping their sporangia and spores. These fronds...

Researchers describe new tardigrade fossil found in 16 million year old Domincan amber

October 6, 2021

Tardigrades, also known as water bears, are a diverse group of charismatic microscopic invertebrates that are best known for their ability to survive extreme conditions. A famous example was a 2007 trip to space where tardigrades were exposed to the space vacuum and harmful ionizing solar radiation, and still managed to survive and reproduce after returning to Earth. Tardigrades are found in all the continents of the world and in different environments including marine, freshwater, and terrestrial.

Tardigrades have survived all five Phanerozoic Great Mass Extinction events,...
