(1) Exploring an extraordinary adaptation machinery in a marine holobiont under shallow-water hydrothermal systems
To survive in a sulfur-rich circumstance, living creatures may evolve unique and adaptive features toward sulfur resistance. In such a harsh environment, hydrothermal vent brachyuran crab, Xenograpsus testudinatus, is the only recorded metazoan species that is endemic to the areas. Such unusual tolerance of those possible creatures has long fascinated researchers. The molecular mechanisms enabling exceptional tolerance have remained largely unknown and could serve as available information regarding one planetary habitability and the origin of life during planetary evolution. These acid-base and ions regulation mechanisms of crustaceans are a key for species evolution and crucial for ecological sustainability in the future. Besides, compared to other research groups studying deep-sea hydrothermal vents, the ease of access to a shallow hydrothermal vent field places us in an advantageous position.

(2) Tropical fish in a thermal-stabilized climate system
Since 2010, an increased occurrence of high atmospheric temperatures and a gradual decline of daily temperature variations in the winter season was recorded in essential aquaculture areas across the south of Taiwan. According to our systematic metabolic profiling method, we found that the transgenerational experience of ambient temperature perturbations can lead to adaptive metabolic allocation features in the liver of tropical tilapia. Because global warming may result in less thermal variation each year, the stabilized ambient temperature may gradually cause tropical tilapia to exhibit lower energy conservation. In addition to those habitants in cold and temperate regions, a lack of cold exposure to multiple generations of fish may decrease the native cold-tolerance traits of subtropical/tropical organisms; this notion has not been previously explored in terms of the biological effects of anthropogenic climate change.

(3) Under the sea: what will happen under acidification and why it matters!
Atmospheric CO2 levels are rising dramatically since industrialization, changing seawater chemistry and causing a drop in ocean pH. This phenomenon has been termed as “ocean acidification (OA)”. OA has been recognized as an emerging abiotic stressor, potentially affecting ecosystems’ biodiversity, concordance and functions. The significant achievement of recent studies is to characterize a feature of epigenetic modifications on epithelial acid-base regulators, as well as behavior appearances were also observed to involve in maintaining transgenerational homeostasis. Those comparison works in terms of physiological plasticity will offer significant insights to the environmental adaption in high power marine taxa towards the future ocean.
