Summary: Research investigates the impact of spatial features on carbon storage and sequestration in urban park greenspace. Lidar point clouds and remote sensing images were used to study carbon storage and driving factors. Results indicate that biodiversity and forest structure are key drivers of carbon density, while water bodies have a larger impact on a larger scale. Texture characteristics provide more insight into carbon density than vegetation index, and RVI is better at explaining carbon sequestration variation than NDVI. This study aids in developing carbon sequestration strategies based on parks.

Summary: After decades of afforestation, China's forest coverage has increased significantly, but the impact of forest quality on ecosystem services remains controversial. Most assessment results show that the increase in forest carbon storage is mainly due to the increase in forest area rather than forest quality. However, these results may be overestimated as they are based on national permanent plots that may be protected or less disturbed.

Summary: The study found that mangrove species diversity has a positive effect on both mangrove biomass production and soil carbon storage. This effect is more evident in forest communities, and is influenced by structural characteristics such as tree stem diameter and tree density. Additionally, areas with high soil nitrogen content and mean annual precipitation show higher mangrove biomass and carbon storage, indicating a relation between climate factors and soil fertility in driving mangrove carbon storage and diversity patterns.

Summary: This study aims to derive null models for the expected number of species shared among multiple samples or habitat patches, exploring the geometric effects of subdivision on species diversity. Results show that the geometric effects of subdivision depend on patterns of spatial distribution of species and evenness of species abundance. Increasing subdivision decreases shared species, increases beta diversity, and results in higher total species richness in subdivided habitat. The models explain why fragmented habitat could have higher diversity than continuous habitat of equal area but predict a threshold patch-size.

Summary: The number of species shared between sites decreases as more sites are included in the comparison, with a rate dependent on the most widespread species. In over 80% of empirical communities, the decline in shared species follows either an exponential or power law form, which are largely untested and poorly understood. Simulation results show that the distribution of widespread species differentiates the two forms, with the power law form favored when such species occupy more than 75% of sites. Empirical data confirms that the form of multisite similarity decline can predict community structures and competitive interactions.
