Daphnia lumholtzi is typically found in the warm, shallow regions [6] of bodies of water with larger surface areas. [7] While most species of Daphnia see high mortality at temperatures greater than 25 °C, [8] D. lumholtzi individuals can survive and reproduce at temperatures up to 30 °C, [8] [9] [10] with a thermal optimum occurring at 29 °C.

Daphnia is a genus of small planktonic crustaceans, 0.2–6.0 mm (0.01–0.24 in) in length. Daphnia are members of the order Anomopoda, and are one of the several small aquatic crustaceans commonly called water fleas because their saltatory swimming style resembles the movements of fleas.
This difference in temperatures can be observed in different seasons and can lead to a high amount of variability between Daphnia, a crucial part of its ability to coevolve with P. ramosa. During P. ramosa infection, the size of the Daphnia increases significantly. This phenomenon is known as pathogen-induced gigantism. In addition, the ...
Daphnia pulex. The genus Daphnia (Crustacea: Cladocera: Daphniidae) contains over 200 species of water fleas, many of which are in need of further taxonomic investigation (species inquirendae; marked with asterisks). [1]
Daphnia magna is widespread in the Northern Hemisphere and in particular in the holarctic. [2] It can be found in fresh and brackish water bodies of different sizes, from lakes to ponds and ephemeral rock pools near the sea. D. magna tolerates higher levels of salinity (up to one-fifth the salinity of sea water) than most other species of the ...
