With spring and summer come farmers markets and a wide variety of fruits and vegetables. In the next two months, berries of a ton of different varieties come into season including, strawberries, raspberries, blackberries and blueberries. Well, I say berries but really only one of the berries mentioned is actually a berry. Guess which one? I’ll wait. As the narrator of a blog piece about botanical fruit varieties I have infinite time.
February is Black History Month in the US and Canada. (In the UK it is observed in October). With the spotlight on Black History, it’s especially imperative that we take the time to focus on African American biologists, ecologists, conservationists and environmentalists (although we environmentalists should be doing this all year).
As the Ordovician period progressed the environment changed. Atmospheric CO2 plummeted from 7000 to 4400 ppm and the Earth cools. This may have been partially caused by green, aquatic algae and land plants as they sucked and sequestered atmospheric CO2.
Last week, I introduced the concept that green algae (but not their brown, red and gold counterparts) are actually plants that outnumber the leafy things we're all familiar with. You were probably left wondering how one gets from Ulva and Volvox to a redwood. As it turns out differences between land plants and green algae have everything to do with the different environmental challenges they face.
