11 Size dependent growth – Linear Models
In posts 1 to10 I have now covered most of the preliminaries for a research report such as aims, methods, sites, assumptions and confounding issues
I live at Maroubra, in Sydney, Australia. I am a relatively fit 70 year old with an enquiring mind and a love of the ocean. I started in marine biology before I was 10, spending much of my beach days poking around in rock pools and crevices.

Choosing and fitting the right growth model is not straightforward.
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
