“…The reported direct effects of temperature have been explained by the 'physiological tolerance' hypothesis and the 'more-individuals' hypothesis, which both predict higher species richness in warmer and less 'energy-limited' environments with benign environmental conditions (Buckley et al, 2012;Currie et al, 2004;Storch et al, 2018). Further, temperature may also indirectly increase species richness of vertebrates, due to positive effects on the occurrence of ectothermic insect prey (Chen et al, 2020;Peters et al, 2016).…”

Given the current challenges of global change, e.g., through increasing temperatures and changes in habitat quality, it is essential to gain a better understanding of how species are linked to the conditions of their environment. Bats and birds fulfill crucial ecosystem functions as highly mobile long-distance seed dispersers, pollinators, and insect predators and might be influenced not only by abiotic conditions such as temperature, but also by structural parameters of their habitats. We hypothesized that mean annual temperature and vegetation structures are key determinants of flying vertebrate species richness along the slopes of Mt. Kilimanjaro, Tanzania. We used Light Detection and Ranging (LiDAR) to characterize the three-dimensional habitat structure across different forest strata and recorded mean annual temperature on 58 study sites along the elevational gradient of Mt. Kilimanjaro. Our results show that both bat and bird species richness were significantly associated with temperature and a LiDAR derived measure of canopy density. In combination, temperature and LiDAR-derived vegetation structure described over 90% of the variability in bat and bird species richness along the elevational gradient. Our findings reveal that climate data and measures of canopy structure obtained by remote sensing can be used to approximate the richness of flying vertebrates on tropical mountains and are highly suitable monitoring tools in conservation programs for these functionally important taxa.

The area of habitat patches is a significant factor when determining species-richness in any given habitat. However, this area effect is not the same for every taxonomic group and can change if is considered together with other habitat variables. The main objective of this study was to identify the importance of wetland area for waterbird speciesrichness when it is considered in conjunction with other habitat variables. Studies published in the Scopus and Web of Science databases in marine/coastal and inland wetlands were reviewed. A vote-counting approach was conducted to evaluate how many studies include area as a major variable, and a meta-analysis was performed to measure the effect size of the relationship between area and species-richness. Area was a significant predictor of waterbird species-richness in most of the studies (28 of 40 studies, 70%) as assessed by the vote-counting approach, and the mean effect size was high (r = 0.81, n = 1 studies) in the meta-analysis. Few studies reported the shape of the relationship between habitat area and species-richness, but most reported a positive correlation. Although the species-area relationship is widely recognized, our review shows that an important proportion of studies (30%) also found that other habitat variables were significant variables when they were considered together with habitat area. Consequently, in the case of wetlands, habitat area should be considered in conservation, but not as the only measure of management and restoration if the objective is to conserve waterbird biodiversity by improving species-richness.

“…The largest mangrove reserve in China, Zhanjiang National Mangrove Nature Reserve, is located in the Leizhou Peninsula and accounts for 33% of the total area of MFs in China. It has been listed by the Ramsar International Convention as an important wetland [23,24]. Moreover, two important mangrove reserves were established in the Beibu Gulf, namely Shankou National Mangrove Natural Reserve and Beilun Estuary National Mangrove Natural Reserve.…”

Mangrove restoration projects are often evaluated based on the increase in mangrove forest (MF) area, but the reliability of this indicator as a measure of successful restoration is questionable. Considering both numerical and quality dimensions, this study assessed mangrove restoration efforts in the Leizhou Peninsula and Beibu Gulf (LP-BG) in China. The hypothesis was that due to the limited social capital investment in mangrove restoration, there exist hierarchical differences in the urgency of mangrove restoration. Time-series Landsat imagery from the Google Earth Engine platform was used to analyze the MF distribution from 2000 to 2020. A resilience indicator, incorporating resistance and adaptive capacity, was constructed to assess MF quality within identified mangrove boundaries. The results revealed an increase in MF area from 6655.87 ha in 2000 to 14,607.93 ha in 2020. However, the majority (79.6%) of MF patches exhibited low resilience (values < 3), with only a minority (51 patches) demonstrating high resilience. Interestingly, MFs within the mangrove reserve displayed higher resilience, but these areas did not exhibit a significant spatial expansion of MFs. These findings highlight the limitation of relying solely on the net growth in the MF area as an indicator of successful restoration. Instead, an ecologically optimal solution is recommended, focusing on expanding conservation boundaries to include remnant MFs outside protected areas, rather than creating new planting areas. This study provides an assessment framework to evaluate the efficiency of mangrove restoration efforts and offers insights for local decision makers to guide future restoration endeavors.
