Determinants of post-fire regeneration demography in a subtropical monsoon-climate forest in Southwest China.

Understanding the determinants of post-fire regeneration is critical for determining an appropriate restoration program following fire disturbances. However, studies addressing the drivers of post-fire regeneration of forests in monsoon climate are rare. This study explored the temporal and spatial variations of post-fire forest regeneration in the Central Yunnan Plateau of Southwest China, and disentangled the direct and indirect effects of the environmental factors via structural equation models (SEMs).

Beta Diversity Patterns of Post-fire Forests in Central Yunnan Plateau, Southwest China: Disturbances Intensify the Priority Effect in the Community Assembly.

Post-fire succession is an ideal case for studying effects of disturbance on community assembly, and the key is to disentangle the contributions of assembly processes to the variation of community composition, namely beta diversity, and the contingent scales. The central Yunnan Plateau of Southwest China is characterized by monsoon related seasonal drought, and frequent forest fires. We sampled five fire sites burned in different years and a middle aged forest, measured species composition dissimilarity and its species turnover and nestedness components, within each fire site and across all sites.

A highly sensitive and wide-ranged electrochemical zinc(II) aptasensor fabricated on core-shell SiO2-Pt@meso-SiO2.

In this work, bi-functional SiO2-Pt@meso-SiO2 core-shell nanoparticles were designed to prepare a highly sensitive and selective electrochemical zinc(II) aptasensor. This core-shell structure boasts its SiO2 mesoporous shell and the inside Pt nanoparticles. SiO2 mesoporous shell can fix aptamer without affecting its configuration and can admit electrolyte through the shell.
