Summary: This study examines the long-term changes in Serengeti National Park (SNP) vegetation from 1982 to 2016, finding nonlinear trends in leaf area index (LAI) driven by temperature and moisture availability. The study highlights the reversal in greening trends during the long rains and greening trends during the short rains, influenced by temperature and moisture variables. The findings demonstrate the complex interactions between vegetation and climate at different temporal and spatial scales within SNP.

Summary: The concentration of sulfate at Grand Canyon National Park has decreased over time due to successful regulations reducing emissions from upwind source regions. Various analysis methods show that the contributors vary by season and region, with different sources being more prominent during winter (Navajo Generating Station and Cholla) and summer (northern Mexico and Arizona smelters).

Summary: The Yarlung Tsangpo Grand Canyon (YTGC) region in China serves as an important gene bank for mountain biological species and provides an exceptional environment for scientists to study organism differentiation. This study evaluates the ecological value of the region and identifies the extremely important areas for conservation. The findings can be used to establish national parks for strict conservation and guide the construction of biodiversity conservation corridors.

Summary: This article examines the impacts and challenges of tourism in towns and cities near protected areas and finds that the lack of data and understanding limits the development of generalizable solutions. The study identifies the factors influencing residents' perceptions and local support of tourism and highlights the importance of community participation, living environment, trust in tourism institutions, tourism benefits, and community satisfaction in driving support for tourism development.

Summary: Through geochemical groundwater sampling in Chaco Culture National Historical Park, it is found that the groundwater in this region is old and geochemically evolved, with a northward flow direction. Evidence suggests mixing between aquifers and hydrocarbons. This study provides new hydrological insights for the region.

Summary: Protected savannas play a crucial role in preserving biological diversity, but excessive grazing by mammals can have cascading effects on communities and disrupt ecosystem functioning. This study examined the abundance, species richness, and composition of arthropods in long-term grazing exclosures in Kruger National Park, South Africa. The results showed that Hymenoptera, Coleoptera, Diptera, and Araneae were the most abundant orders of arthropods sampled. The abundance and species richness of certain orders, such as Diptera and Hymenoptera, varied significantly between exclosures. The study concludes that long-term mammal grazing can enhance species richness and niche composition, leading to the presence of unique and sparse arthropods in protected savannas.

Summary: Northern protected areas play a crucial role in safeguarding habitats and species, but their fixed spatial boundaries make them highly susceptible to environmental changes. Using satellite remote sensing and geostatistical modelling, a study focused on Torngat Mountains National Park in Canada revealed the drivers of land cover change and predicted future expansion of shrub vegetation based on biotic and topographic variables. The study anticipates a significant increase in shrub cover by 2039/43, emphasizing the importance of establishing long-term monitoring plots to validate remote sensing observations and understand the impacts on the tundra ecosystem.

Summary: Examining the characteristics and spatial patterns of vegetation change under different protection levels can provide a scientific basis for national park protection and management. The study analyzed the vegetation change in Wuyishan National Park using Landsat EVI data from 1986 to 2020 and the WBS approach. The results showed that the highest percentage of area without abrupt change was in the strictly protected area, while the non-protected area had the lowest percentage. The study also found that the vegetation coverage generally improved in the park, with higher positive percentage in the protected areas. However, the non-protected area had a higher mean greenness change. The study highlighted the importance of protection level in determining vegetation change and spatial patterns in the national park.

Summary: This study investigates the impact of treated wastewater effluent on the Colorado River watershed in the Grand Canyon National Park using anthropogenic chemical tracers. The results show the presence of various anthropogenic compounds in Bright Angel Wash and Monument Spring, indicating the influence of treated wastewater. The use of anthropogenic tracers provides valuable insights into the geological structures and their role in water flow.

Summary: Restoration has become a global priority, with initiatives such as the UN Decade on Ecosystem Restoration. Monitoring vegetation recovery using NDVI and EVI showed non-linear patterns in forest regeneration, with an initial increase in both indices indicating successful onset of forest recovery. Differentiation between primary forests and regenerating forests was possible based on unique combinations of low mean and seasonal variation in EVI.

Summary: Accurately understanding the relationships between wetland ecological restoration plant communities and their species diversity is crucial for wetland management and biodiversity protection. In this study, we investigated the effects of different ecological restoration models on plant communities, species diversity, and soil properties in the Xinqiang River National Wetland Park in China. We identified common characteristics among different restoration types and key community traits that can enhance species diversity. These findings provide a theoretical basis for the coupling relationship between ecological community characteristics and species diversity, with practical implications for maintaining ecological structure and biodiversity protection.

Summary: This study investigates the impact of bush encroachment on biodiversity conservation and tourism in Bwabwata National Park, Namibia. The research shows that woody vegetation has increased by 13% since 1999 and that both early- and late-season fires are effective in managing bush encroachment. The study recommends using early dry-season fires to reduce encroachment rates and maintain a heterogeneous vegetation structure.

Summary: This study introduces a new iterative clustering method REMOS based on silhouette width and compares its performance with the existing algorithm OPTSIL. REMOS algorithms showed faster runtime and lower misclassification rate compared to OPTSIL, making them preferable in certain scenarios where reducing negative silhouette widths and time efficiency are important factors.

Summary: This study reveals that the size and fragmentation of climate conditions play a crucial role in biodiversity and species turnover among terrestrial tetrapods. By considering both climate characteristics and its geographic attributes, we can explain almost 90% of global species richness variation, with half of the explanatory power attributed to climate or the geography of climate.
