Summary: As the taxonomic knowledge of cyanobacteria from terrestrial environments increases, it is important to analyze biodiversity in understudied areas. This study describes several new species in three genera and suggests that cyanobacterial genera may be widely distributed across global hemispheres, while distinct lineages exist at the species level.

Summary: The Channel Islands of California have attracted attention due to their long occupation history spanning over 13,000 years. The Northern and Southern Channel Islands exhibit different environmental contexts, impacting the cultural adaptations of their inhabitants. Recent research on under-analyzed data from the Eel Point site on San Clemente Island aims to shed light on long-term human-environmental interactions and the cultural impacts of climatic change in Mediterranean environments.

Summary: Studies of marine terraces and their fossils provide important information about sea level history, tectonic uplift rates, and paleozoogeography. The well-preserved marine terraces on Santa Rosa Island, California, show low uplift rates during the late Pleistocene. Fossil mixing on these terraces may be caused by glacial-interglacial cycles and variations in sea surface temperature during the early Pleistocene.

Summary: The study presents a sub-adult burial from Gua Makpan, Alor Island, Indonesia, dated to the early mid-Holocene, suggesting a delayed primary burial or secondary treatment. The mortuary practices in this burial are compared to those from other sites in Island Southeast Asia, revealing differences and similarities that may inform on shared mortuary rituals across the region and changing social practices with migrations or the introduction of new burial practices.

Summary: San Pedro Martir island, a biosphere reserve, is rich in biological and ecological importance. Most species found are commercially important, with 11 listed as protected. Although the abundance of some commercial species is decreasing, the ecological indicators suggest that the reserve is in good condition.

Summary: Island spotted skunks, a rare subspecies endemic to the California Channel Islands, were found to have distinct evolutionary history and isolation patterns from mainland spotted skunks. Through the sequencing of mitochondrial genomes, it was determined that these island populations were colonized by a single ancestral population during the early Holocene and have remained isolated from each other ever since the split of the super-island Santarosae into Santa Cruz and Santa Rosa islands about 9,400-9,700 years ago. Due to their unique characteristics and current population status, island spotted skunks may require management as distinct evolutionarily significant units.

Summary: The study focused on the ecosystem of San Clemente Island, using satellite data to show the significant impact of clouds and fog on the island's environment, particularly in terms of shading and moistening. Analysis revealed June as the cloudiest month on the island, with intra-day cloud albedo variability up to 20% and interannual and monthly variability around 10%. The dataset can be utilized to model vegetation distribution and understand ecological phenomena and patterns.

Summary: This study reanalyzes morphometric and meristic data of island night lizards from three California Channel Islands and finds significant differences in results compared to a previous study, mainly due to differences in data treatment and statistical analysis methods. The findings of this study are important for implementing effective resource management programs.

Summary: The uplifted coastal terraces on Santa Catalina Island are poorly preserved due to geological conditions and high landslide susceptibility, which erase terrace morphology and deposits. Other Channel Islands have better preserved terraces, with Santa Rosa having the most extensive terraces due to its shallowly dipping sedimentary rock. Subhorizontal sedimentary units seem to be ideal for promoting terrace formation and resistance to erosion.

Summary: This study examines the geomorphological features of San Nicola Island and investigates the role of litho-structural and tectonic features in landslide occurrence and distribution. The results provide valuable insights for landslide hazard assessment and territorial planning in small insular areas with similar geological-geomorphological features and landscape values.

Summary: Understanding the pollination requirements of endangered species and the effects of different pollination treatments on reproductive output and fitness is crucial for long-term conservation strategies. This study found that facilitated pollination and outcrossing significantly improved the reproductive output and fitness of a rare island endemic plant, despite it being fully self-compatible.

Summary: The study found that marine fishery products, including grouper fish, in the waters near Pramuka Island, Indonesia, have been contaminated with microplastics, but the uptake of microplastics in the fish was low and did not affect the individual body length.

Summary: Surveys conducted on San Clemente Island off southern California by the California Beetle Project and the Santa Barbara Botanic Garden discovered four specimens of an unknown bark beetle species. Based on morphology, the beetle was identified as a Carphobius Blackman species. Molecular phylogeny using COI and 28S gene sequences confirmed its placement in the Carphobius genus and raised questions about its current tribal placement. A new species, Carphobius caterinoi Cognato and Smith, was described and compared to previously known species. The review of Carphobius includes a species key and images, and discusses potential host use by C. caterinoi.

Summary: The discovery of ancient fin whale bones on California's Channel Islands provides insights into the distribution and human use of these large cetaceans. The bones found in archaeological sites offer valuable information about the past distribution and utility of various whale species, although some bones cannot be identified to a specific genus or species level.

Summary: The study found that the abundance of microplastics in water and sediment was higher in Untung Jawa Island, and the digestive tracts of sea urchins also contained more microplastic particles. In contrast, Tidung Island had lower levels of microplastics in water, sediment, and sea urchin digestive tracts.

Summary: This study represents the first application of Organic Residue Analysis (ORA) to southern African early farming pottery to gain a deeper understanding of past human behavior and subsistence patterns. The study found evidence of dairy processing and multi-purpose functionality of the ceramics. It also discovered potential medicinal use and the involvement of dung in pottery sealing and mending.

Summary: Chemical treatment of skeletal remains can reduce overall DNA quality and quantity but has no significant impact on stable isotope ratio analysis. Examination of treated and untreated human remains through histological and stable isotope analysis reveals that treated remains exhibit better preservation compared to untreated remains. Stable isotope ratio analysis is viable for both treated and untreated remains, regardless of their origin.

Summary: This paper presents the outcomes of a microcontextual geoarchaeological study conducted on earthen dwellings from the Early Iron Age village of Cerro de San Vicente. The study employed soil micromorphology, lipid biomarker analysis, XRD, and XRF analyses to investigate various aspects of the dwellings, including construction materials, site formation processes, and daily life practices. The results have shed light on the construction layers, floor use, maintenance, repaving, periods of abandonment and decay, and the presence of lipid biomarkers associated with dwelling functionality. The study significantly contributes to our understanding of ancient construction practices and the utilization of domestic spaces during the Early Iron Age.
