Summary: This study examined the relationship between area and species richness in littoral fish assemblages of a fragmented river in south-central Ontario, Canada. The findings suggest that area and vegetation cover diversity have a significant impact on species richness, with species accumulating rapidly with an increase in fragment area. This study highlights the potential importance of mitigating local extinction due to small population sizes and enhancing aquatic vegetation cover for promoting species diversity in fragmented rivers.

Summary: The study revealed that as the degree of non-native species invasion increases, species-area relationships (SARs) worldwide significantly strengthen, reshaping SARs. Native species still exhibit stronger SARs, with steeper slopes compared to non-native species. Additionally, there are differences in filling new niches among invading taxonomic groups.

Summary: In this study, we investigated the species-area relationships (SARs) for skin-borne symbiotic microbes of wildlife hosts. We found that symbiotic microbial SARs were complex, with both U-shaped and inverted U-shaped models being widely favored over the power-law model. Different habitat-specific amphibian hosts did not show distinct microbial diversity and skin-related SAR patterns.

Summary: This study utilized DAR modeling to analyze the diversity of the human virome, revealing that inter-individual virome diversity showed no significant differences between healthy and diseased individuals; potential maximal accrual diversity may vary between healthy and diseased groups or different body sites; bacterial communities exhibit much smaller LGD ratios compared to viral communities, indicating greater heterogeneity between local and global diversity levels for bacterial biomes.

Summary: Differences in tree species richness between South America and Africa are primarily due to certain key families in South American moist forests and dry vegetation types. The tree floras of South America and Africa are organized similarly, and further research on these key families could provide insights into the processes leading to South America's exceptional plant species diversity.

Summary: This study assesses the relationship between the northern latitudinal limits of tree species in North America and winter coldness and temperature seasonality. It finds that winter coldness is more strongly associated with species distributions at high latitudes and is a more important driver of the latitudinal diversity gradient.

Summary: This study focused on the species-area relationship (SAR) of ants, using data from insular ant communities to examine the effects of climate, biogeographic realms, and latitude on SAR slope values. The study found differences in SAR slopes and intercept values between mainland and insular systems, with evidence of thresholds in the global insular SAR. The general slope coefficient for insular systems was observed to be lower than in previous studies, highlighting the need for further research on the influences of climate and biogeographic realms on ant SAR.

Summary: During the Cretaceous period, terrestrial vertebrates experienced diversifications and turnovers due to global geographical change, although the poor fossil record from the early Late Cretaceous has concealed how dinosaurs and other terrestrial vertebrates responded to these events. This study describes two dinosaurs from the North American paleolandmass Appalachia, shedding light on the timing of important anatomical innovations in two widespread dinosaur lineages. The phylogenetic positions of the dinosaurs show similarities between Appalachian and Eurasian dinosaur faunas, indicating a degree of endemism in Appalachian dinosaur assemblages due to episodes of vicariance.

Summary: This study investigates the time-frequency dependency between government expenditures and tax revenues in the United States from 1960Q2 to 2019Q3, using the wavelet coherence approach. The findings support the spend-and-tax hypothesis, suggesting that government expenditures have both short-term and long-term effects on tax revenues within specific time intervals.

Summary: This article examines the end Permian to Middle Triassic interval, which witnessed a significant marine mass extinction and delayed recovery. The focus is on Triassic marine sediments in South China, providing unique documentation of the collapse and recovery of marine ecosystems. Several papers analyze different fossils and their ecological significance, while others study biostratigraphy, reconstruct paleoenvironments, and link records to volcanic eruptions.

Summary: This study provides a comprehensive overview of the dynamics of the upper branch of the Atlantic Meridional Overturning Circulation (AMOC) in the mid-latitudes of the Northeast Atlantic. It focuses on the European Slope Current (ESC) and its glacial equivalent known as the Glacial Eastern Boundary Current (GEBC). The study reveals significant changes in flow strength and ventilation during the glacial and deglaciation periods, as well as a gradual weakening of the slope current during the Holocene.

Summary: The cause of ice-age cycles is still not fully understood, and studying the timing and magnitude of mountain glaciations can provide valuable insights. This study presents new dating results from the Niqingqu Valley in the Tibetan Plateau, showing multiple glacial activities prior to the Penultimate Glacial Maximum. The findings suggest that low atmospheric CO2 content and reduced summer solar insolation/high summer-monsoon precipitation played a role in these glacial fluctuations.

Summary: Through sediment records from Lake Nanyi in the lower Yangtze, we found that anthropogenic fire activity played a dominant role in the region, and the temporal pattern of fire activity was asynchronous from east to west. Archaeological evidence suggests an inverse relationship between agricultural and population levels and fire intensity during the mid-Holocene, with fire intensity being influenced by the diversity of landscape types associated with pre-historic subsistence patterns. Overall, changes in regional water-level delayed the transition from hunting-gathering to agriculture in the lower Yangtze region.

Summary: This paper argues that sessile barnacles are an excellent proxy for palaeoenvironmental reconstructions. The shells of barnacles consist of diagenetically stable low-magnesium calcite and record short-term variations. Analyses of several Western Mediterranean barnacle-rich deposits demonstrate the utility of barnacles as proxies for water depth, distance from the coastline, and hydrodynamic conditions. Moreover, the stable isotope ratios of barnacle shells can provide detailed palaeoenvironmental information.

The findings show how variations in sea surface temperature, eustatic sea level, and tectonics have influenced the development of the atoll. These findings have broader implications for understanding the Quaternary evolution of similar tropical carbonate atolls in the region.

Summary: The Epivillafranchian and the transition to the Galerian was a period of environmental fluctuations and faunal turnover. Hominins and giant hyenas could coexist during the Epivillafranchian, but the transition to the Galerian led to a disruption of the scavenging niche, coinciding with the extinction of P. brevirostris.

Summary: The Late Ordovician mass extinction occurred during an ice age, with maximum ice coverage and a substantial drop in global sea level. This led to the exposure or shallowing of shallow tropical shelf environments. The study suggests that the burial rate of nutrient phosphorus (P) on shelves was minimal during this glacial period, leading to excess bioavailable P entering the open ocean and stimulating phytoplankton production, which in turn lowered oxygen concentrations.

Summary: This study investigates the temporal evolution of neritic carbonates in the proto-South China Sea to reconstruct East Asian monsoonal currents and winds during the middle to late Paleogene. The results highlight that many of the features of the summer East Asian Monsoon large-scale circulation are rooted in the middle Paleogene.
