Population Size and Habitat Use by <i>Tachypleus tridentatus</i> in the Taiwan Straits.

ABSTRACT: The adult population of Tachypleus tridentatus on the main island of Taiwan has long been considered extinct. However, it remains unclear whether this apparent absence reflects true extirpation or simply a lack of sustained large-scale monitoring. To address this knowledge gap, a multiyear field investigation was conducted from 2018 to 2024 across three key subregions of the Taiwan Strait, namely, Kinmen, Penghu, and mainland Taiwan. Mark-recapture methods were used to estimate the adult population size using two statistical approaches. Population size estimated from the Schnabel method presented 73,629 (95% CI: 59,555-96,415) in Kinmen, 1551 (968-3899) in Penghu, and 1099 (623-4627) in Taiwan main island. Multinomial N-mixture models showed a population size of 65,428 (63,704-67,15
