Additions to the freshwater fauna of Heard Island

Abstract

. Freshwater collections fr om Heard Island yielded a fauna of protozoans, one species of platyhelminth, two species of tardigrades, at least four species of nemarodes, 16 species of rotifer (including two new species and four new records for the island), one species of enchytraeid worm, and nine species of arthropod (four anomopodans, two copepods and three mites). No ostracods were found, nor was any evidence of insects with aquatic or semi-aquatic larvae.

“…In total, 25 species of rotifers belonging to the Brachionidae family have been identified from the Antarctic and sub-Antarctic region (Table I), including a mixture of cosmopolitan and endemic species. Lepadella triptera, with its wide distribution (Segers 2007) which has been recorded on the sub-Antarctic islands of South Georgia (Dartnall 2005b), Marion Island (Smith & Dartnall, personal communication 2010), Iles Kerguelen (De Smet 2001), Heard Island (Dartnall 2003), and Macquarie Island (Dartnall 1993, Dartnall et al 2005, as well as on Signy Island in the Maritime Antarctic (Dartnall & Hollowday 1985). Philodina alata is an Antarctic endemic species that was originally described from the McMurdo Sound area (Murray 1910) and has repeatedly been reported from there by Dougherty & Harris (1963) and Cathey et al (1981).…”
