<small>The ecosystem of the pond we investigate is located in the Ilm Park, that is a 48-hectare landscape park on the edge of Weimar's Old Town. It was gained from nature and further shaped between 1778 and 1828. The park contains valuable trees, mostly local varieties (Some imported from southern Germany), but also some foreign trees, especially from North America; bushes were also planted.</small> | <small>The ecosystem of the pond we investigate is located in the Ilm Park, that is a 48-hectare landscape park on the edge of Weimar's Old Town.

The ponds in the Park are in two different categories: They are formed either by running water (Pon1) overflowing from underwater supplements into puddles or by rainwater collecting (Pond2). The running water is clearer and deeper and it's surface is more open to the light. It has watergrass on the surface, and we have found Dracunculus medinensis worm and Cyclops in it. | |||

In our research, we initially studied both ponds and compared them together. | In our research, we initially studied both ponds and compared them together. | ||

As temperatures dropped, we observed a decrease in algae count in all the samples collected from various areas of the pond. | As temperatures dropped, we observed a decrease in algae count in all the samples collected from various areas of the pond. | ||

In January, the pond had significantly more water than in autumn, which may contribute to increased algae growth, as they tend to rest and produce less in cold weather. | In January, the pond had significantly more water than in autumn, which may contribute to increased algae growth, as they tend to rest and produce less in cold weather. | ||
