[ Get Data ]

Abstract: Population connectivity and gene flow in near shore Antarctic Echinoids (Sterechinus neumayeri, Abatus nimrodi and Abatus ingens) was investigated in East Antarctica. This data set consists of microsatellite genotype data from 11 novel loci and mitochondrial DNA sequences from two gene region, COI and 16S. In addition, to determine if changes in temperature and salinity impacted fertilisation ... View entire text

Quality Microsatellite data:
Some null alleles were detected, with some individuals not amplifying at individual loci.

Fertilisation data:
After initial collection prior to sea ice breakout, all urchins collected post sea ice breakout had completed their spawning cycle, preventing repetition of the experiment.

Collection dates:
Casey Abatus samples: November 13, 2006 to December 14, 2006
Davis Abatus samples: January 27, 2010 to February 25, 2010
Casey Sterechinus samples: January 14, 2009 to January 29 2009
Davis Sterechinus samples: 29 Between November 12, 2009 and February 22, 2010
