Wisdom of the Summer Solstice

On June 21st, the Sun will swell to a dramatic crescendo on the longest day of the year in the Northern Hemisphere, Summer Solstice. Across history, cultures and geography, humans have paid special attention to this annual event, holding it as a day of ritual and reverence. The Summer Solstice stands as a threshold between Spring and Summer, marking a time to savor abundance and fresh starts.  

Why I study Phenology

Why I study Phenology

I study phenology, or the timing of seasonal biological events such as such autumn leaf death and spring budburst. The transition to spring is a particularly exciting event to witness. It’s also an incredibly complex process, involving cellular pathways and genes that are not well understood, and affected by winter temperatures, spring temperatures, and day length, among other things. The beauty apparent in observing phenology in nature and the complexity of biology underlying phenological events fascinate and ground me.

Two-minute-takeway: What is Phenology?

Phenology is the study of the timing of recurring biological events.

You’ve probably heard the expression “timing is everything” and, indeed, when events such as flowering or insect emergence occur can determine life or death. If a tree bursts its buds too early in the spring, for example, frost may damage or kill the new leaf tissue. If it bursts its buds very late, on the other hand, it may be at a competitive disadvantage compared to other trees that began photosynthesizing and growing earlier in the season.
