Spatial Conservation Prioritization

Summary There have been calls for the expansion of protected areas (PAs) to tackle the ongoing biodiversity loss, yet it is unclear where future PAs might help to protect biodiversity in degraded landscapes under the conservation planning principles of complementarity, connectivity and cost-effectiveness. Our conservation goal is to increase the PA network coverage to up to 30% of the landscape of the Zhangjiang River Basin for target species in the karst area of southwest China, a global biodiversity hotspot. Zonation 4GUI was used to evaluate the adequacy of current PAs and to strategically expand PAs while maximizing the coverage of target species and considering ecological integrity and socioeconomic activities. The results show that significant habitat degradation has occurred across 77.9% of the basin. The current PAs cover 6.3% of the site and represent 8.7% of the total distribution of key species. With regards to the threshold of protection of 30% of the area, protecting an additional 27.2% of the site under an ecological integrity prioritization scenario and a scenario of the socioeconomic costs involved in iteration would cover 93.5% and 80.4% of the ranges of the key species, respectively. Our results can be used to inform the upcoming actions associated with karst area conservation-related policies.

Abstract Long-term droughts were found to have guided the environmental selection ofshrub plant characteristics in a karst region of China, as the plants were found to have developed a set of leaf trait combinations,includinga small specific leaf area (SLA), leaf area (LA), and large leaf dry matter content (LDMC), that are known to be suitable for drought environments.Leaf traits of plants are not only the intuitive and operable taxonomic traits in plant taxonomy, but also reflect the responses and adaptations of plants to their habitats. This is helpful when trying to understand the role of environmental screening and when filtering plant functional traits. The objective of this investigation was to determine the leaf trait variations, adaptations, and patterns in the shrubs from a karst region in China.Weinvestigated 11 leaf traits to quantify the variations in their trade-offs and the trait–habitat /species relationships for the shrubs at theHuanjiang karst ecosystem observation and research station, China, using multivariate analyses.There were significant intraspecific and interspecific changes in the leaf traits ofthe shrub plants, and there were differences among the traits. Except for carbonmass, nitrogenarea, and phosphorousarea, the interspecific variations of the leaf traits were generally higher than the interspecific variation. The correlation between the leaf traits in the karst shrubs was also significant. Species differences had a higher explanatory degree for the leaf traits than topography or soil nutrients. The findings of this study will enhance our understanding of the variations in leaf traits in the karst shrubregions and the adaptative strategies of the plants in degraded habitats.Furthermore, these results may provide scientific information to help guide vegetation recovery programs in the karst region of southwest China.

AbstractMountains of Southwest China (MSWC) is a biodiversity hotspot with a very unique and highly complex terrain. However, with the majority of studies focusing on the biogeographic consequences of massive mountain building, the Quaternary legacy of biodiversity for the MSWC has long been overlooked. Here, we took a comparative phylogeography approach to examine factors that shaped community-wide diversification. With data from 30 vertebrate species, the results reveal spatially concordant genetic structure, with temporally clustered divergence events during severe glacial cycles, indicating the importance of riverine barriers in the phylogeographic history of the vertebrate community. We conclude that the repeated glacial cycles are associated with temporal synchrony of divergence patterns that are themselves structured by the heterogeneity of the montane landscape has of the MSWC. This orderly process of diversifications has profound implications for conservation by highlighting the relative independence of different geographic areas in which communities have responded similarly to climate changes and calls for further comparative phylogeographic investigations to reveal the extent to which these findings might apply more broadly to other taxa in this biodiversity hotspot.
