Canadian Yew Stomata 1000x
Stomata are a pair of cells on leaves, seeds, flowers; they are crucial for plant survival and thus, for all life on earth.
Grasslands give way to deserts on a warming planet.
Western Red Cedar Stomata
Stomata draw in CO2, and "exhale" water and oxygen.
Camas Lily Pollen 3400x
Climate change is leading to higher pollen levels, resulting in increased asthma and allergies.
Willow Stomata 2400x
Trillions upon trillions of stomata on all the plants of the world help drive the climate. All of the moisture in the atmosphere cycles through this "system" twice each year.
Red Algae and Diatoms 1000x
As ocean temperatures rise, some diatom populations are declining. Diatoms produce half of the globe's oxygen. These diatoms are one hundredth of a pinhead wide.
The ginkgo is one of the oldest living tree species on Earth. For over 200 million years, the ginkgo has adapted to numerous cycles of climate warming and cooling. Could this rune-like stomata have something to do with its long success?
Grass Spikes 1000x
Grass will need more than clever ways of being transported in order to adapt to droughts.
Holly Stomata 1300x
As temperatures rise with climate change, some stomata close, robbing plants of carbon, which leads to early plant death, especially in the tropics.
Hummingbird Feather Forest 2200x
With warming temperatures, flowers bloom earlier in the spring. Will hummingbirds migrate in time to help pollinate these flowers and obtain food for their young?
Paper Birch Stomata
Paper birch thrive in cold conditions; as temperatures rise, birch stands are dying out in the USA.
Grasses such as wheat, rice and corn, provide half of the world's food supply. Grass stomata have four cells rather than the normal two, with more resistance to drought, but fast changes could overwhelm this defense.
Poplar Stomata 3400x
There are proposals to plant extensive poplar plantations to store carbon, or turn the trees into ethanol for fuel, but this is controversial.
Paper Wasp Nest Fibers 200x
Researchers in Britain have found that over the last forty years, wasps favor warmer temperatures, and their numbers are increasing.
Stinging Nettle Stomata 1300x
Nettles are high in nutrients and minerals. With climate change, nettles and crucial food crops have fewer nutrients but more carbs, like junk food.
Invasive species such as this blackberry in the USA are expected to out-compete native plants
Rain prompts these seeds to spin and drill themselves into the ground.
Camas Sepal Stomata 2200x
The whole sequence of wildflower blooms is becoming less predictable, disrupting ancient pollinator/plant relationships.
Arbutus Seeds 90x
More frequent summer droughts in the Pacific Northwest, USA, create dangerous stress for Arbutus trees.
Wildflower Anther 540x
Increased drought shrivels crops and flowers.
