This study explored the influence of climatic oscillations on the striped, blue, and silver marlin catch rates in the Indian Ocean by using logbook data from Taiwanese large-scale fishing vessels and climate records from 1994 to 2016. Only the Madden-Julian oscillation (MJO) and the subtropical Indian Ocean dipole (SIOD) had immediate effects on the striped and silver marlin catch rates. The positive and negative phases of the IOD at the lags of 7 and 3 years corresponded to increased and decreased catch rates, respectively, for both the striped and blue marlin, contrasting to the reverse pattern for the silver marlin.

To optimize conservation and restoration efforts, it is crucial to understand their habitat preference in response to changing environments. In this study, ensemble modeling was used to investigate the seasonal distribution patterns of Spanish mackerel.

View Article and Find Full Text PDF, which belongs to the family Araliaceae, is an endemic and endangered species of Hainan Island, China. It has potential economic and medicinal value owing to the presence of phenylpropanoids, flavonoids, triterpenoids, etc. The analysis of the structure and characteristics of the chloroplast genome (cpDNA) is crucial for understanding the genetic and phylogenetic evolution of this species.

When the sampled data require complex computation for 24×7, the processing element will a consume significant amount of energy and computation resources. Several new sensing algorithms use deep neural network algorithms and consume even more computation resources.

View Article and Find Full Text PDFis an endangered species with inhabiting dense forest along valleys, and it is one of the representative species of tropical rain forest in Hainan Island. In this paper, we reported and characterized the complete chloroplast genome sequence of the species assembled from short reads generated by Illumina sequencing. The size of chloroplast was 152,829 bp, a pair of inverted repeats (IRs) separating a large single copy and a small single copy, the size of IRs, LSC and SSC were 20,036 bp, 93,872 bp and 18,885 bp, respectively.

We show that band gaps in a helix structure may result from Bragg resonance or non-Bragg mechanism. The two types of gaps exhibit distinct optical properties and display an opposite dependence with respect to structural periodicity.
