Since my whole project on growth is based on measurements, a critical element to consider is measurement error. (See Wang et al, 1995 and Francis,
An interesting statistic in any tagging study is the tag loss rate. It is a vital element where the study looks to quantify mortality, movement,
My previous post was about Lunella torquata data. This post is about Turbo militaris, the second species in my research. For all sites except Mahon
I have finished tagging now that my research permit has expired, so I have “closed off” my data and can begin final analyses. Recaptured shells
Tagging Methods Tagging commenced in April 2018 and will continue until April 2024 at five sites (all ~ 500–1000 m2) off southern Sydney, and another
My intention was to compare population structure and growth rates at sites with varying degrees of exposure to ocean swells and different subtidal habitat
