Abstract

Marine mammals use sound for virtually every critical life function, from communication to navigation and passive listening for foraging and spatial orientation. Some species have specialized echolocation systems that allow fine-scale orientation and prey detection. While they inhabit naturally noisy environments, added noise from human activities can interfere with these functions by influencing their behavior, physiology, hearing, and ultimately survival. There has been major progress in the s...

Abstract

In the vast marine ecosystems, the burgeoning issue of anthropogenic noise—emanating from sources like shipping, construction, and military operations—poses a significant challenge to the well-being of diverse marine species. These disturbances interfere with essential biological processes, including communication, behavior, and physiological functions. Amidst the sparse literature on direct assessments, metabolomics emerges as a pioneering technique, offering an innovative lens to scrutinize un...

Abstract

Coral reef is a vulnerable and diverse ecological system in the ocean. The reef soundscape is also diverse and encompasses biophony, geophony and anthrophony. However, extracting specific target sounds of aquatic animals has been difficult in a coastal and noisy environment. In the present study, phonations of small animals in coral reefs, such as damselfish and crustaceans, were recorded passively; using a paddling kayak as a silent platform, faint vocalizations of individual fish and crustacea...

Abstract

The Taiwanese government has been actively promoting green energy development, particularly in the western region, focusing on areas such as Miaoli and Changhua, which are prime locations for offshore wind power projects. Comprehensive environmental impact assessments (EIAs), which include passive acoustic monitoring, are essential both before and during offshore wind farm development to mitigate auditory effects on marine organisms. This precaution is especially crucial due to the presence of t...

Abstract

Blue carbon refers to organic carbon sequestered in marine ecosystems, which can make a significant contribution to the removal of carbon dioxide from the atmosphere. Coastal blue carbon ecosystems are important transition areas connecting land, ocean, and even freshwater, including mangroves, salt marshes, and seagrass beds. Among the three major coastal blue carbon ecosystems, mangroves are the most widely distributed in Taiwan. The electrical resistivity tomography (ERT) method has been used ...
