• Spatial and cross-seasonal patterns of coral diseases in reefs of Taiwan: high prevalence and regional variation.2018 · Although research on coral diseases is increasing worldwide, it remains limited in Taiwan. Taiwan is located at the Tropic of Cancer and contains both tropical and subtropical reefs. We conducted spatial and cross-seasonal surveys in Taiwan in 2018 and identified 7 types of disease and nondisease lesions and 6 potential factors influencing coral health. The overall mean prevalence of disease and nondisease lesions varied considerably across the reef regions, and host susceptibility differed among the coral taxa. The overall mean prevalence of disease and nondisease lesions was highest in Kenting (mean ± SEM: 8.58 ± 1.81%) and lowest on the Southern Islands (2.12 ± 0.73%). Although the prevalence of diseases did not differ significantly between the seasons, cyanobacteria-related diseases—including black band disease (BBD), BBD-like syndrome, and other cyanobacterial syndromes—were slightly more prevalent in autumn than in spring. Furthermore, 3 of the potential factors influencing coral health (i.e. turf algae, bioeroding sponges, and coral bleaching) were strong predictors of disease and nondisease lesion prevalence. These results advance our understanding of coral disease ecology in Taiwan and highlight the need for further research on the correlations between diseases, hosts, and environment.
