“…Expanding and enhancing protected areas are fundamental for maintaining ecosystem functions and protecting the Earth's biodiversity [25]. Numerous studies indicate the effectiveness of protected areas for local biodiversity [26,27], water and soil retention [28], carbon sequestration [29], and human well-being [30]. However, there is still an ongoing debate on the positive role of protected areas in the global situation.…”

Protected areas are fundamental for maintaining ecosystem functions and have generally been considered to affect land use change. Here, we explored how protected areas affected land cover volatility in China from 2011 to 2020 with LandTrendr using the Google Earth Engine (GEE) platform by comparing the difference in volatility of the Normalized Difference Vegetation Index (NDVI) in protected and unprotected areas. The results show that the regions with frequent land cover volatility are mainly located in eastern, central, and southwestern China, indicating that land cover volatility with high NDVI loss values is spatially aggregated in most cases. Considering the impact of protected areas, land cover volatility is relatively consistent inside and outside the protected area throughout the study period, showing a trend of first fluctuating and then rising. Approximately 22% of detected land cover volatility occurred in protected areas, though the average NDVI loss value (0.56) for protected areas was greater than unprotected areas (0.51). Combined with the outliers, land cover volatility accompanied by larger NDVI loss values is still primarily distributed in unprotected areas in most years. The detection of NDVI gain values in protected areas shows that protected areas (average value is 0.48) are larger than unprotected areas (average value is 0.47) almost every year, even combined with the outliers, and land cover volatility accompanied by larger NDVI gain values is also primarily distributed in protected areas in most years. Elucidating land cover volatility is helpful in understanding land cover changes and how to formulate an effective land use policy.

“…Tropical reefs are no exception, with degraded states and processes projected to worsen in the long term due to escalating human pressures [4][5][6] . Given the diverse and essential contributions to people provided by tropical reefs, such degradation will have overwhelming consequences for human livelihood and welfare, primarily in developing countries 7 .…”

Towards process-oriented management of tropical reefs in the anthropocene

Tropical reefs and the fish relying on them are under increasing pressure. Shallow-reef fish provide important ecological information in addition to sustaining fisheries, tourism and more. Although empirical metrics of fish biomass are widely used in fisheries management, metrics of biomass production—how much new biomass is produced over time—are rarely estimated even though such production informs potential fisheries yields. Here we estimate fish standing biomass (B), biomass production (P, the rate of biomass accumulation) and biomass turnover (P/B ratio, the rate of biomass replacement) for 1,979 tropical reef sites spanning 39 tropical countries. On the basis of fish standing biomass and biomass turnover, we propose a conceptual framework that splits reefs into three classes to visualize ecological and socio-economic risk and help guide spatial management interventions (for example, marine protected areas) to optimize returns on conservation efforts. At large scales, high turnover was associated with high human pressure and low primary productivity, whereas high biomass was associated with low human pressure and high primary productivity. Going beyond standing fish biomass to consider dynamic ecological processes can better guide regional coral reef conservation and sustainable fisheries management.

“…Rivers are among the most impacted ecosystems worldwide, being difficult to mitigate the multiple impacts on fish communities, and where the engagement of local communities and stakeholders in the application of protection measures is a key factor in managing the effectiveness of the protection in PAs (Fidler et al, 2022;Pereira et al, 2022). Additional management measures, such as removing barriers or building fish passes, are needed to allow the long-distance migratory fishes to complete their breeding cycle (Hermoso et al, 2015).…”

Protected areas (PAs) are the cornerstones of global biodiversity conservation efforts, but to fulfil this role they must be effective at conserving both habitat and species. Among protected taxa, freshwater fish are exposed to multiple disturbances and are considered one of the most endangered. The Natura 2000 reserves network was established with the aim of preserving biodiversity across Europe, but few assessments have been made on its effectiveness on the conservation of freshwater fish species. We tested the hypothesis that fish community is exposed to less anthropogenic pressures within the Natura 2000 sites than outside, hosting a higher number of native species and maintain lower number of non-native species. We tested these hypotheses considering 3,777 sampling sites, found across the entire Italian territory. Results showed that PAs did not guarantee less anthropogenic impacts and higher fish species richness than outside PAs, suggesting that PAs are not a panacea for anthropogenic pressures and safeguarding fish diversity. Nevertheless, more caution should be applied to the management measures and the design of new PAs due to the limitations of the protection of a single stretch within a whole river ecosystem. Moreover, the impossibility to operate any management of invasive fish species on the broad scale of a whole river basin is likely the most limiting factor to fish biodiversity conservation in Italy. Finally, it is also necessary to extend the analysis to other basins and Natura 2000 sites in Europe.
