This Week in Nature: March 21-27

“Daffodils that come before the swallow dares
And take the winds of March with beauty.”
— Shakespeare

Here’s what’s happening this week in nature.

Jupiter:

Jupiter evening and the moon

Jupiter will be visible in the evening sky throughout spring. In the mornings of March 21 and 22, both Jupiter and our Moon will appear together.

 

Penumbral Lunar Eclipse:

A penumbral lunar eclipse on March 23 will be visible from Oceania, Asia, and western parts of North America. When the Moon passes through the outer part of Earth’s shadow, a slight darkening results on the Moon’s edge. The word penumbra stems from the Latin words paene, meaning “almost,” and umbra, meaning “shadow.”

 

Buzz Pollination:

When collecting pollen from some flowers, bumblebees clutch them tightly and vibrate their large flight muscles so the pollen loosens, causing the pollen to stick to them first before being collected.

 

Middle Frost:

spring thaw

Spring temperatures start ground thaw at the top and bottom; the middle section is the last to thaw. A “frost front” advances extremely slowly into the soil. Instead of moving maybe 20 mph or faster as weather fronts can, a frost front might move down an inch or so a day. In the Spring, even as the air begins to warm, the ground’s frost front that began the previous Fall is still moving down.

 

Fast Flowers:

stinging nettle

Species such as the stinging nettle appear early in spring to establish territory before the big-leafed trees’ foliage grows to block their sun.

 

Frog Songs:

green frog rana clamitans

60 degrees Fahrenheit (16 degrees Celsius) marks the beginning of toads’ trilling. And when the days warm to 70 degrees Fahrenheit (21 degrees Celsius), green frogs begin to call.

My “This Week in Nature” posts are not meant to be specific to any one geographical area. They are intended to evoke the essence of the seasons and to emphasize the cycles of nature. The goal is to simply offer a glimpse of the natural phenomena that make each day an amazing event.
