Over the weekend, we took benefit of the nice and cozy autumn climate to scrub 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 might be a number of causes for this specific tadpole not creating. For instance, it might have a genetic abnormality that forestalls this tadpole from altering. It might stay a tadpole for the rest of its life.

A September Tadpole
The cool and moist climate in June might have prevented the tadpole from creating 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 progress stunted.
We definitely had lots 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 publish 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 is perhaps a method to make sure extra of the progeny survive. For instance, the circumstances in the summertime may not be splendid for the survival of the froglets as they emerge from the water. So, if among the tadpoles stay within the pond till the next spring, the circumstances may need improved thus allowing them a better probability of survival.
At the very least one tadpole from the workplace pond is prone to overwinter. Image credit score: All the things Dinosaur.

We’ve taken out among 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 report relationship again to the Cretaceous.
We will maintain checking on the tadpole and the opposite pond life over the autumn and winter months.
