1 Introduction

This file contains the code for analysis in R for a study about resources use in sea snakes on the west coast of India.

The core message of this manuscripts are as follows:

  • Resource use differs between H. curtus and H. schistosus
  • Variation in fishing intensity of trawlers and gillnets affects patterns of resource use

We used a combination of approaches including:

  1. fisheries dependent methods to characterise distribution and habitat use of the two species, and spatial overlap with fishing;

  2. visual gut content analysis to characterise diet and trophic niche of the species, and overlap between fisheries catch and sea snake diet;

  3. stable isotope analysis to characterise overall resource use in terms of isotopic niche, as well as the effect of fishing intensity on the niche width of both species.
