Spatio-temporal variability among loggerhead turtle, Caretta caretta strandings off southern Brazil
<p>This package contains data and R code for the models of the article Fonseca et al. "Spatio-temporal variability among loggerhead turtle, <em>Caretta caretta</em> strandings off southern Brazil", accepted for publication at ICES Journal of Marine Science. Datasheet "Carettacaretta_strandings_Fonsecaetal2024.csv" contains stranding assessment, necropsy, and biometric information per individual (i.e. Date and time of recording, sex, development stage, size, interaction with anthropogenic activities). All <em>C. caretta </em>stranding data are publicly available in the “Sistema de Informação de Monitoramento da Biota Aquática - SIMBA 1.0.0” platform at <a href="https://simba.petrobras.com.br/simba/web/sistema/" target="_blank" rel="noopener">https://simba.petrobras.com.br/simba/web/sistema/</a>.

(c) Number of species: outer doughnut chart indicates the relative number of species collected in each bromeliad in a respective phase, larvae and imagines (the sum is not 100% due to species occurrence on both bromeliads); in the inner pie chart the light grey is the percentage of species collected only on V. friburgensis; grey is the percentage of species collected only in H. augusta and dark grey is the percentage of common species collected on both species of bromeliads. (d) Abundance of beetles on both bromeliad species discriminated by larvae and imagines.
