Summary: Longitudinal movement plays a crucial role in the habitat colonization and population establishment of riverine fish species. However, the fine-scale movement patterns and recruitment habitats of amphibious fish species are still poorly understood. This study analyzed the ear-bones of Galaxias maculatus to assess its fine-scale longitudinal movement variability and found that it predominantly recruits in freshwater and estuarine habitats, with slow-flowing or stagnant habitats providing suitable prey for its larvae.

Summary: The study compared the live weight and shell length between different shell colors of the giant triton snail (Charonia tritonis) using Multivariate Analysis of Variance (MANOVA). Sequence analysis of the mitochondrial cytochrome oxidase (COI) gene was also conducted to assess the affinity of C. tritonis with two different shell colors. Additionally, phylogenetic trees were constructed using the maximum likelihood (ML) and Bayesian Inference methods, and haplotype network diagrams were constructed. The results showed that the population size of C. tritonis remained relatively stable, and the genetic and size differentiation between the two different shell colors was small.

Summary: At the end of the last ice age, Atlantic salmon populations became landlocked in lakes and ponds of the Northern Hemisphere due to river blockages caused by land movement. This resulted in a different evolutionary pattern compared to anadromous salmons. Our study using whole genome data revealed a significant reduction in genetic diversity and an increase in homozygosity in landlocked salmon populations, indicating a recent population bottleneck. The findings suggest that landlocked waterbodies serve as islands, influencing the evolution of fish populations.

Summary: This study calculated fluctuating asymmetry values of the two otolith parameters - length and width of Engraulis australis, which were recovered from the food of gannets living on islands at Hauraki Gulf, New Zealand. The dissimilarity value of otolith width was found to be higher than that of otolith length, and there was an increase in dissimilarity values with fish length for the otolith sizes studied. The dissimilarity values were lowest for fish with a total length of 115-154 mm, and highest for fish with a length of 151-160 mm, possibly due to contaminants present in the study location.

Summary: Past research identified a copepod parasite (Pharodes tortugensis) on common gobies in the British Virgin Islands, but subsequent DNA barcoding revealed multiple host species and confirmed the parasite as a single widespread species. The interaction between Pharodes and Coryphopterus significantly impacts host dynamics in the BVI.

Summary: Pyroxene crystals from Central Plateau tephra are used to infer formation conditions, showing pseudo-pressures and temperatures at high oxygen fugacity and mid-to-upper crustal pressures. The data suggest uptake of high-temperature pyroxenes into ascending andesitic melts, precluding the presence of long-lived crustal mush zones in the studied tephras. Models of arc andesite genesis without a deep crustal hot zone beneath the Central Plateau are possible.

Summary: Rhinogobius gigas, an amphidromous fish endemic to eastern Taiwan, has a limited distribution range due to its short marine larval duration, resulting in higher genetic homogeneity and recent population expansion. The lack of genetic structure among populations suggests a complex interaction between short pelagic larval duration, interspecific competition, and coastal currents in eastern Taiwan.

Summary: This study examines the impact of religious release fish on environmental conservation through questionnaire surveys and mark-recapture studies. The results suggest that public understanding of the impact of religious release fish is limited, and hatchery-reared black porgy may make up a significant portion of the population in northern Taiwan waters. The similar length distribution between hatchery-reared and wild stocks indicates that they may not interact with each other.

Summary: This study investigated the demographic structure of the narrow-barred Spanish mackerel in the northwestern Pacific, including Taiwan's waters, by analyzing growth parameters, age composition, mortality, and sex ratio. The results indicated that the S. commerson caught in the central Taiwan Strait are mainly young fish aged 1(+) to 2(+) years. The estimated fishing mortality and exploitation rate suggested that overfishing was not occurring in this stock, contributing to the understanding of population dynamics and aiding in the management and conservation of this species.

Summary: The Ortosuu and Uchkuduk regions of the Tianshan orogen in China contain basaltic rocks with different characteristics in the lithospheric mantle beneath. Petrology, chemical composition, and P-T geotherm data from xenoliths within the basalts reveal two groups of clinopyroxene based on their Mg# and trace element patterns. The distribution of rare earth elements suggests that the different clinopyroxene groups have different origins, with one group likely derived from the uppermost mantle and the other group derived from a depth close to the crust mantle boundary.

Summary: This study demonstrates that type II methanotrophs in the root tissues of paddy rice perform methane oxidation and nitrogen fixation simultaneously at the single-cell level. The findings provide direct evidence of the activities of methanotrophs in root tissues, suggesting that they may provide fixed nitrogen to root systems or depend on different microenvironmental niches.

Summary: We investigate the polycrystalline powder samples of Co-substituted Mg3_xCoxTeO6 (x = 0.0-2.4) using X-ray diffraction, magnetic susceptibilities, and specific heat analysis. The non-magnetic parent compound Mg3TeO6 has a trigonal R3 space group structure. The Co-substituted samples have a similar crystal structure to the parent compound, with distorted (Mg/Co)O6 and TeO6 octahedra observed through Rietveld refinements of synchrotron X-ray diffraction data. Interestingly, a magnetic phase transition from a non-magnetic ground state to an antiferromagnetic order through a cluster glass state is observed, where the antiferromagnetic order emerges above the percolation threshold (x > 1.0) and the cluster glass state is stabilized for x = 0.8.

Summary: Through analyzing muscle, otolith organic matter, and fish diet, it was found that the delta N-15 values were highest in muscle, followed by otoliths, diet, and plankton. There was no significant difference in delta N-15 values between otolith and diet. However, there was a small but significant difference in delta C-13 values between muscle and otolith in farmed fishes. This research is important for studying the feeding ecology and nutrition behaviors of fish.

Summary: Research shows that the mercury accumulation rate in bluefin tuna is highest in the Mediterranean Sea, decreases in the North Pacific, Indian Ocean, and North Atlantic Ocean, correlating with the concentrations of MeHg in regional seawater and zooplankton. These differences are related to the levels of mercury in each ocean subbasin, geogenic enrichment, and anthropogenic contamination.
