Summary: This study assessed the genetic diversity and phylogeographic structure of 45 populations of Chondrus from Korea, China, and Japan, and found moderate intraspecific genetic diversity and high-level intraspecific gene flow among regions. The comprehensive genetic information provides insights into the phylogeographic patterns and intraspecific diversity of Chondrus species, emphasizing the need for conservation of natural resources.

Summary: Research revealed the existence of more cryptic species within the Sillaginidae family in the Indo-West Pacific region, with swim bladder evolution corresponding with phylogeny. It is suggested to treat different Sillaginidae species as separate management units.

Summary: In this study, the phylogeography of Derris trifoliata in the Indo-West Pacific region was investigated. The results revealed distinct clades and divergence in different oceanic regions, indicating population differentiation during the late Pleistocene. Genetic differentiation was influenced by barriers to gene flow, geographical distance, and current patterns of oceanic circulation. The fragmentation of D. trifoliata's once widespread distribution was attributed to changes in climatic suitability and biogeographic barriers during the Pleistocene.

Summary: This study investigated the genetic population structure of the Japanese flounder in six populations in China. The results showed that the peripheral Fuqing population in the East China Sea had relatively low genetic diversity and high differentiation. Additionally, the study revealed that the Japanese flounder experienced population expansion during the Pleistocene.

Summary: This study examines the impact of Pleistocene glacial cycles on the distribution and genetic structure of endemic invertebrate species in the Pacific Northwest. The results show that glacial periods reduced habitat suitability and increased habitat fragmentation, leading to intraspecific divergence and secondary contact between populations. The findings suggest that refugial dynamics played a significant role in driving population structure and gene flow in these species.

Summary: This study demonstrates the relative significance of ecological mechanisms in shaping microbial communities in the Pacific Ocean, specifically in terms of selection, dispersal, and drift. Temperature plays an important role in determining the importance of homogeneous selection and dispersal limitation in community assembly. Co-occurrence-based community metrics are found to be better indicators of biogeographic patterns compared to compositional or phylogenetic distance measures. These findings contribute to our understanding of microbial community assembly processes and their role in global biogeochemical processes.

Summary: The disjunct temperate rainforests in the Pacific Northwest of North America are characterized by two dominant tree species, western redcedar and western hemlock. The demographic histories of these species have been influenced by geological and climatic changes over the last 5 million years, including glaciations. Genomic data analysis reveals that both inland and coastal populations of these species diverged around 2.5 million years ago and experienced population size changes during glacial cycles. Importantly, there was evidence of gene flow between coastal and inland populations during the mid-Holocene.

Summary: This study characterizes the topographic evolution of the Pacific Northwest, United States during the Cenozoic, with a focus on the polygenetic history of Cascade Mountain uplift along-strike. The Washington Cascades experienced steady uplift throughout the Cenozoic, while the Oregon Cascades reached similar elevations by the late Oligocene before topographic stagnation.

Summary: The study presents oxygen isotope and charcoal accumulation records from lakes in eastern Washington, with sufficient resolution to compare with tree-ring records and meteorological data. The findings show that the wetter conditions during the Medieval Climate Anomaly (MCA) compared to the Little Ice Age (LIA) were reflected in the oxygen isotope measurements. Additionally, the charcoal records indicate increased fire activity during the LIA. The study also reveals increased hydroclimate variability after 1250 CE in western North America.

Summary: Bacteria and microeukaryotes play important roles in global biogeochemical cycles. In this study, the distribution patterns and assembly mechanisms of these microorganisms in the tropical North Pacific Ocean were investigated. The results showed significant biogeographic patterns and diversity differences between regions for both bacteria and microeukaryotes. The correlations between spatial and environmental variables and the alpha and beta diversities of these microorganisms were similar. Ecological drift was the main mechanism driving the bacterial communities, while heterogeneous selection, dispersal limitation, and ecological drift collectively explained the turnover of microeukaryote communities.

Summary: This study characterized the population genetic structure of the purplish bifurcate mussel in the northwestern Pacific, identifying two mitochondrial lineages (southern and northern) that may have diverged due to historical sea level fluctuations and adaptation to different temperature zones. Discordance between mitochondrial and nuclear markers suggests potential cryptic speciation and the need for further genomic analyses to explore this divergence.

Summary: This study identifies historical geoclimatic factors that have resulted in low genetic diversity and strong phylogeographic structure in a cryptoviviparous mangrove species. The findings suggest conservation actions and highlight the importance of phylogeographic studies for understanding genetic diversity and conservation implications.

Summary: Considerable research has been done on the genetic structure of sharks and rays, with a focus on their life history traits, evolutionary history, and environmental factors. This group is highly vulnerable to human-induced stressors due to their late maturity and low fecundity. The study provides a review and synthesis of the global phylogeography of 40 shark species and 19 ray species. The findings show the influence of various factors, such as reproductive philopatry, site fidelity, and dispersal ability, on the population genetic structure.

Summary: This study models the distribution of non-native cattail in the Fraser River Estuary using spectral imagery analysis and species distribution modeling. Contrary to expectations, non-native cattails are widespread in the estuary, with hybrid cattail appearing to be more abundant. The study highlights the vulnerability of estuaries to cryptic invasions and the invasibility of Pacific Northwest estuaries by non-native cattail.

Summary: The study reveals that two sister clades of the genus Elachistocleis originated in the Andes, diverging in the mid-Miocene, potentially dispersing to Trinidad through the dried-out river systems in South America, and spreading from Venezuela and Guyana to the island facilitated by a lowering sea-level.
