Nature: microsites

Self-tutoring about nature: the tutor mentions an observation.

A couple of weeks ago the sun was brilliant, so I went for a run. Overnight, it had been cold. However, I did the run at 1pm, when the temp was around 8°C.

I was somewhat surprised to see, behind a hedge, frost still in the grass. There was none in the sunlight, but the sun is low at this time of year: that patch of ground had been in shade all day, and would continue to be. Even in a surrounding temperature of 8°C, the frost persisted. I don’t doubt it lasted into the night.

That location, perhaps 25 square feet, is an example of a microsite: a place with particular conditions not experienced in its immediate surroundings. Especially plants and mushrooms, since they can’t move, might be bound to a particular microsite because it’s the only place that offers the habitat they need. Their seeds or spores reach everywhere, but only those in favourable microsites will grow. The next closest one that’s suitable may be a hundred feet away or a mile away: plants and mushrooms depend on the randomness of nature to broadcast their seeds or spores so they can discover and then populate such favourable places.
