Summary: This study analyzed the venom of Lataste's viper from different populations in Portugal and compared the differences in venom composition between juvenile and adult specimens. The results showed that there are ontogenetic changes in the venom composition and geographic variability in venom profiles. Factors such as body size and sex of the vipers were also found to be potentially related to venom variation.

Summary: This study analyzed the variation of sexual dimorphism and ontogenetic trajectories in different populations of the common lancehead Bothrops jararaca. The results showed that females were larger than males in all populations, with females in the coastal population generally smaller but with more scales than those in the highland population. These differences may be attributed to the availability of prey and climatic conditions.

Summary: Studies of the black-capped and Carolina chickadee hybrid zone show movement of the zone towards the northwest over the past 36-38 years, but at a slower rate compared to the eastern portion of the zone. Differences in temperature trends between the eastern and western areas may explain the slower movement of the hybrid zone in Missouri.

Summary: Terrestrial ecosystems in the Loess Plateau have significant carbon sequestration potential, and land use changes play a crucial role in carbon storage. Over the past 20 years, carbon storage in the plateau has increased by 28 Tg (0.56%). Under different land use scenarios, carbon storage is expected to further increase by 2035, with the highest potential in the ecological protection scenario. Spatial distribution of carbon density is closely related to land use types, and the northern Qinling Mountains, Taihang Mountains, and Lvliang Mountains have the highest carbon density.

Summary: This study focused on the Northern Hemisphere and used data from the Total Column Carbon Observing Network (TCCON) to assess the accuracy of Greenhouse Gases Observing Satellite (GOSAT) Proxy XCH4 data. Spatial-temporal distribution of XCH4 and its driving factors were analyzed and quantified using geographic detectors. Results showed an increasing trend of XCH4 from 2009 to 2021, with anthropogenic activities identified as the main influencing factor. The findings provide a scientific basis for future management of this greenhouse gas.

Summary: This study reveals that compensatory base changes (CBCs) in the secondary structure of ribosomal internal transcribed spacer 2 (ITS2) impact genetic distance estimation. The results show that the existence of CBC substitutions inflates ITS2 genetic distances to a varying extent, with a possible deviation of 180% higher if the substitution rate ratio in ITS2 stems is three times higher than in loops. However, the CBC effect is minor in lineages with a ratio below two, indicating that the DNA model is still applicable.

Summary: Land change modeling is a complex GIS procedure aiming to predict future land cover changes, contributing to the design of interventions that preserve ecosystem services and mitigate climate change impacts. The land change model for Greece identified four dominant land cover transformations from 2001 to 2011 and projected future land cover changes up to 2030, indicating that historical trends will continue with sustainable scenarios accelerating woody vegetation expansion.

Summary: The spatiotemporal patterns of lateral change in salt marshes along the Oregon coast vary depending on complex drivers of marsh morphodynamics. Factors influencing salt marsh expansion or contraction were identified through time-series analysis of marsh edge position and area in five estuaries with different morphologies, sediment supplies, sea level change, and vertical accretion rates. The results suggest that marsh expansion occurs when there is enough space for growth and high sediment supplies, while marsh contraction is likely the result of reduced sediment supply and changes in hydroclimate. These findings highlight the importance of considering past land use and time-varying hydroclimate in understanding current salt marsh trajectories.

Summary: The study found that climate change has a potential impact on the distribution of potatoes in China, leading to a shrinking of climate suitable areas and expansion to the east while shrinking to the north. The consistency between major planting areas and high climate suitability areas decreased, and potato planting in low climate suitable areas may have adverse effects on production.

Summary: This study standardized the CPUE of southern bluefin tuna from the Korean tuna longline fishery using generalized linear models. The study found that the standardized CPUE decreased until the mid-2000s and has been increasing since then. The targeting patterns of Korean tuna longline vessels vary spatially, seasonally, and over the long term.

Summary: Improving habitat quality is crucial for biodiversity conservation. This study used the InVEST and PLUS models to assess habitat quality and degradation in the Ebinur Lake Basin from 1990 to 2020 and predict land use change under different scenarios. The findings showed an increase in cultivated land, grassland, and construction land, and a decrease in forest land, water bodies, and unused land. Habitat quality showed an increasing trend followed by a decreasing trend. Ecological zoning identified key protected areas, key restoration areas, and moderate development zones. Comparing the ID and EP scenarios in 2030, the EP scenario led to an increase in high habitat quality, benefiting the ecological security of the basin.

Summary: The rapid development of subway systems in big cities has led to the planning and construction of new lines. Understanding passenger flow change in expanding subways is crucial for planning and operating new networks. This study uses smart card data to simulate the change in passenger flow and finds that the geographic properties of new subway lines can affect the passenger flows of existing sections. A semi-supervised co-training model is developed to predict passenger flow change, achieving higher accuracy compared to benchmark models.

Summary: To improve the regional ecosystem service functions and cope with climate change, it is crucial to study the spatial distribution of land use/cover change (LUCC) and ecosystem services (ESs). This study proposes a framework integrating the PLUS and InVEST models to analyze the spatial agglomeration of ESs and investigate the driving factors. The results show that the combination of CMIP6 and PLUS models effectively simulates land use and ESs exhibit good clustering in different scenarios, with GDP and precipitation as important factors.

Summary: Based on CA-Markov and SWAT, this study simulates the future runoff change in the Yellow River Basin, finding that average runoff will increase in the future period, leading to a higher probability of flood disasters. LUCC will further increase the likelihood of future flood disasters, while the decreasing spring runoff proportion raises the risk of spring drought. On the other hand, the winter runoff proportion is expected to increase.
