Growth and age across range extension region of Centrostephanus rodgersii in eastern Tasmania and morphometric comparison of urchins inhabiting kelp versus barrens habitats
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.

- 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.

- 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). Urchins were recaptured a minimum 12 months later (the recovery area also includes collecting animals from a 5m buffer zone around the plots). Each animal was measured (TD), and Aristotle's lantern removed and placed in 12.5% sodium hypochlorite for 48 hours to remove tissue. Jaws were then checked under UV light for the fluorescent tag mark. When found, the growth increment was measured to the nearest 0.05mm using callipers.
