Summary: This study introduces mangrove ecosystems into ecological footprint accounting and assesses the eco-environmental benefits of mangrove conservation in China. The results showed that despite the limited area, mangrove forests have high carbon sequestration capacity and significant ecological footprint and biocapacity. Therefore, mangrove conservation in China should focus on ecosystem health and expanding the area of forestable land.

Summary: Forest canopy structural complexity (CSC) increases as a power law of forest height, with differences observed in evergreen needleleaf forests compared to other forest types. The relationship between forest height and CSC has broad implications for modeling, scaling, and mapping forest structural attributes.

Summary: Mangroves are one of the most productive ecosystems on Earth, playing a critical role in providing environmental services and livelihood support, while facing alarming rates of global loss. They are increasingly recognized as cost-effective nature-based climate solutions due to their carbon sequestration and storage capacity. Research shows that the USA leads in both the total number of published articles on mangroves and citation counts, while China and Australia excel in specific categories.

Summary: Detection and mapping of snow melt onset and snow extent using Synthetic Aperture Radar (SAR) is crucial for various applications. This study investigated the time-series evolution of radar backscattering coefficients during the spring melt seasons in Apex River, Canada. The results suggest that the cross-polarization (HV and VH) backscatter signal is more suitable for snow melt onset and snow/ground detection compared to conventionally used HH and VV signals.

Summary: The study investigates the shift in species dominance in the mangrove microalgae community in Cross River Estuary System (CRES), Nigeria, and evaluates the water quality variation. Diatoms are found to be the most abundant and diverse group of microalgae in the estuary. The microalgae community composition varies spatially, with different regions being influenced by turbidity, salinity, and nutrient concentration. Certain microalgae species are identified as potential indicators of environmental changes in marine waters.

Summary: Drop on demand (DoD) inkjet printing is a high precision, non-contact, and maskless additive manufacturing technique utilized for producing high-precision micrometer-scaled geometries. This study investigates the influence of main printing parameters on the accuracy of a representative geometry and determines the optimal parameter combination. The results indicate that choosing the highest speed value within the investigated range can increase productivity.

Summary: Aboveground carbon storage in forests is influenced by both structural and compositional diversity of plant communities. This study analyzed data from tropical forest plots in Hainan Island, China, and found that structural diversity had a greater impact on aboveground carbon in the overstory stratum compared to compositional diversity. The relationship between diversity and carbon was slightly affected by soil nutrients but strongly influenced by altitude. Altitude indirectly affected overstory tree height and diameter diversity through species diversity, ultimately impacting aboveground carbon storage.

Summary: The study found that ecosystem services in the karst region have changed over the past decade, primarily influenced by vegetation recovery and the conversion of farmland to forest. While human pressure on land has decreased, the trade-off between carbon sequestration and water yield still needs to be considered.

Summary: This study analyzed the structures of fish assemblages and their relationships with environmental variables in two adjacent estuaries on the north Pacific coast of Mexico. The results showed that habitat characteristics significantly influenced the composition, biomass, and diversity of fish assemblages. The depth and salinity also played a role in the diversity of fish assemblages. These findings highlight the singularity of fish assemblages in estuaries and emphasize the importance of local management strategies for these ecosystems.

Summary: Due to their tropical location, mangrove forests are vulnerable to hurricane impact. A study conducted in a mangrove area in Mexico showed that remote sensing approaches can accurately monitor the damage and recovery of the mangrove canopy. The hurricane caused a significant defoliation of the mangrove canopy, but the UAV images indicated a gradual recovery, which is estimated to take at least 8.5 years to reach pre-impact conditions.

Summary: This study used multiple satellite and drone-based imagery, as well as biophysical variables, to monitor the natural recruitment and expansion of Laguncularia racemosa mangroves on mudflats within an ephemeral inlet in Mexico. The study found that when the river mouth closes, sediment accumulation creates favorable conditions for Laguncularia racemosa propagules to establish and grow under minimal water level variability and low salinity. These findings contribute to the understanding of natural Laguncularia racemosa recruitment in highly dynamic systems.

Summary: The study explores the spatial patterns of crime in a small northern city and assesses the degree of similarity in these patterns across seasons. Results indicate that crime calls are more dispersed in the warmer seasons of spring and summer, with increases in hotspot intensity but little overall change in pattern. The SPPT test finds some evidence for seasonal differences in crime patterns across the city, specifically for thefts and break and enters.
