Over the weekend, we took benefit of the nice and cozy autumn climate to wash and tidy up the workplace pond.  To our shock we found a single tadpole.  This September tadpole had not metamorphosed right into a frog however had remained in its juvenile state.  We’ve seen this phenomenon earlier than, and there may very well be a number of causes for this specific tadpole not growing.  For instance, it may have a genetic abnormality that forestalls this tadpole from altering.  It may stay a tadpole for the rest of its life.

A September Tadpole

The cool and moist climate in June may have prevented the tadpole from growing correctly.  Tadpoles feed on algae, maybe there was a scarcity of meals or an excessive amount of competitors and this tadpole, plus others we didn’t spot, have had their development stunted.

We actually had plenty of frogspawn within the workplace pond this 12 months.  In complete we counted 13 batches of spawn.  The frogspawn is being laid earlier within the 12 months.  For instance, this 12 months’s spawning began in the course of February.

To learn our weblog put up in regards to the first frogspawn noticed this 12 months: Frogspawn Noticed within the Workplace Pond (2024).

While the overwhelming majority of the tadpoles flip into frogs in a single 12 months, some appear to take longer. This may be a method to make sure extra of the progeny survive.  For instance, the circumstances in the summertime won’t be superb for the survival of the froglets as they emerge from the water.  So, if a number of the tadpoles stay within the pond till the next spring, the circumstances may need improved thus allowing them a higher likelihood of survival.

We’ve taken out a number of the weed however left loads of oxygenating crops.  We’ve tidied up the waterlilies too.

Waterlilies belong to the household Nymphaeaceae.  These crops have a fossil document courting again to the Cretaceous.

We will preserve checking on the tadpole and the opposite pond life over the autumn and winter months.
