Nest temperatures for green turtles (Chelonia mydas) nesting on Ascension Island, South Atlantic (7°57'S 14°22'W), were examined. Temperature probes were placed into nests on two beaches, Long Beach (26 nests) and North East Bay (8 nests). Within these beaches there was relatively little thermal variation (SD of nest temperature was 0.32°C for Long Beach and 0.30°C for North East Bay). To examine inter-beach thermal variation temperature probes were buried at 55 cm on 12 beaches. Inter-beach thermal variation was large and was related to the beach albedo with the darkest beach (albedo, 016) being 4.2°C warmer than the lightest coloured beach (albedo, 0.73).

A New Species

Material from the Cyperus appendiculatus group was collected from Ascension Island and compared using a common garden study and to herbarium specimens from throughout the geographical range. Cyperus stroudii is described as a new species, known only from Ascension Island in the South Atlantic Ocean, it closest relative is C. appendiculatus also native to Ascension Island and Brazil. Cyperus stroudii differs from C. appendiculatus in its dwarf habit and other morphological characteristics, and these characteristics are retained under common environmental conditions indicative of genomic differences.
