Bosmina freyi

De Melo & Hebert, 1994

Bosmina freyi is a small cladoceran in the Bosminidae, described by De Melo and Hebert in 1994. It inhabits freshwater environments, with documented in tropical eutrophic . Research has examined morphological plasticity in this , particularly variation in body size, mucron length, and in response to environmental conditions.

Habitat

Freshwater environments including tropical eutrophic . Documented from riverine and lacustrine zones, with occurring at different depths within the photic zone.

Distribution

Neotropical region. Documented from Brazil (states: Amazonas, Bahia, Ceará, Distrito Federal, Goiás, Maranhão, Minas Gerais, Mato Grosso do Sul, Pernambuco, Piauí, Paraná, Rio Grande do Sul, Santa Catarina, São Paulo, Tocantins). Nearctic records also reported.

Ecological Role

Part of zooplankton in freshwater . As a filter-feeding cladoceran, contributes to water column and serves as for and fish.

More Details

Morphological plasticity

B. freyi exhibits significant morphological variation in response to environmental variables. In a tropical study, individuals showed heterogeneous distribution of traits including body size, mucron length, length, and antennule aperture percentage across different zones and depths. Smaller body size individuals were associated with longer mucrons and antennules and smaller antennule aperture angles in the riverine zone and subsurface waters.

Taxonomic note

The epithet 'freyi' honors someone, though the original description context is not provided in available sources. The species was established relatively recently (1994) compared to many other Bosmina species.
