Full description

The barrens-forming sea urchin Centrostephanus rodgersii has undergone poleward range extension to eastern Tasmania. This data compares growth, morphology, reproductive investment and gonad indices between individuals inhabiting barrens ('barrens-maintaining' urchins') with those found on kelp beds ('barrens-forming' urchins) in north eastern Tasmania. The data set is comprised of 3 files. The first (Centrostephanus_biometrics_kelp_vs_barrens_urch.xls) compares biometrics of urchins across 3 sites and 2 habitats in eastern Tasmania. The second (Copy_of_Centrostephanus_annual_jaw_growth_increments.xls) compares annual growth increments of urchins in kelp bed and barren habitat including an additional site in south eastern Tasmania (The Lanterns - Tasman Peninsula) to allow comparison of growth across the newly extended range. The third (Jaw_TD_allometery.xlsx) provides a conversion between the allometry of jaw length and test diameter. Ultimately a generalised growth model for the sea urchin in kelp bed habitat was obtained for eastern Tasmania.

Statement: Study sites (eastern Tasmania): WGS84 St Helens (-41.242666, 148.33633): 2 sites (n = 341 and 383 urchins tagged) Tasman Peninsula (-43.1365, 148.0035): 1 site (n = 250 urchins tagged)
Statement: Growth and age patterns C. rodgersii ranging 61-133mm test diameter (TD) in size were tagged using an injection of 2-4 ml fluorescent tetracycline through the peristomial membrane. Individuals were measured (TD) using vernier callipers, and then placed in a permanently marked plot (8 x 8m).

Purpose
To compare life history characteristics between urchins inhabiting urchin barrens to those found within seaweed beds. This includes data on age/growth, morphology, reproductive investment and gut index. To compare growth across the extended range and develop growth models such that age structure of the population can be estimated.
