Assessment Information [top]

Red List Category & Criteria:	Data Deficient ver 3.1
Year Published:	2007
Assessor/s:	Miller, K.A., Garske, L. & Edgar, G.
Reviewer/s:	Stuart, S.N. & Carpenter, K.E. (Global Marine Species Assessment Coordinating Team)
Contributor/s:
Justification: This species is difficult to distinguish from S. galapagense with sterile material, and there is insufficient data on population trends to have confidence in threat assessment, hence listed as Data Deficient.

Geographic Range [top]

Range Description:	Sargassum templetonii is endemic to the Galápagos Islands. Prior to 1983, reported from: Isabela: Punta Albemarle (Taylor 1945) and Punta Cristopher (Taylor 1945); Floreana; San Cristóbal; Santa Cruz: Academy Bay (Wellington 1975). After 1983, reported from: Santa Cruz: Tortuga Bay (1989 CDS), Punta Carrion and Mosquera; Isabela: Caleta Tagus (CDRS record 2002), Punta Albemarle and Castles; Fernandina: Punta Española; Santa Fé: Roca Pinguina.
Countries:	Native: Ecuador (Galápagos)
FAO Marine Fishing Areas:	Native: Pacific – southeast

Population [top]

Population:	S. templetonii is uncommon throughout its distribution. No data are available on population trends.
Population Trend:	Unknown

Habitat and Ecology [top]

Habitat and Ecology:	S. templetonii has been reported to occur at depths of 4.5 to 7.5 m on saxicolous subtrata. However, at Santa Fé juveniles were reported at 24 m (UC, K.A. Miller pers. comm.) and juveniles at Punta Albemarle were observed at >28 m.
Systems:	Marine

Threats [top]

Major Threat(s):	Presumably El Niño and climate change. Ecosystem interactions involving these two factors appear to have caused widespread decline in algal populations because of an increase in density of grazing sea urchins and other herbivores, following overexploitation of predators along with ENSO disturbances.
