“…In other words, they are rarely found in forested habitats and remain quite mysterious due to their small populations. Furthermore, China covers a vast geographical area with diverse landscapes, and its southwestern area is recognized as one of the most globally biodiverse hotspots [ 109 ], but only one Osphya species was recorded from Mainland China, except from two species from the islands of Taiwan. Perhaps fewer distribution records of Osphya in these regions indicate a relative lack of collection efforts, but it is more likely that this reflects a reasonable distribution pattern when considering the biogeographical history (discussed as above) and environmental factors.…”

“…All the important factors that affect the potential distribution and survival of Osphya are closely related to precipitation and temperature. It is suggested that water–energy factors dominate the formation of insect diversity, and inappropriate water–energy can exert a significant impact insect distribution, morphology, phenology, and even survival [ 109 , 129 ]. However, the bionomics of Osphya were actually very little known.…”

“…Therefore, we cannot determine whether results obtained by SDMs using bias data are reliable or not. In addition, a taxonomists’ specialization of taxon studies may be another potentially important factor affecting the data integrity, especially for those rare or endemic groups, which will inevitably enlarge the data bias and impede the building of SDMs [ 109 ].…”

Exploring the development of species distribution patterns under climate change is the basis of biogeography and macroecology. However, under the background of global climate change, few studies focus on how the distribution pattern and the range of insects have or will change in response to long-term climate change. An old but small, Northern-Hemisphere-distributed beetle group Osphya is an ideal subject to conduct the study in this aspect. Here, based on a comprehensive geographic dataset, we analyzed the global distribution pattern of Osphya using ArcGIS techniques, which declared a discontinuous and uneven distribution pattern across the USA, Europe, and Asia. Furthermore, we predicted the suitable habitats of Osphya under different climate scenarios via the MaxEnt model. The results showed that the high suitability areas were always concentrated in the European Mediterranean and the western coast of USA, while a low suitability exhibited in Asia. Moreover, by integrating the analyses of biogeography and habitat suitability, we inferred that the Osphya species conservatively prefer a warm, stable, and rainy climate, and they tend to expand towards higher latitude in response to the climate warming from the past to future. These results are helpful in exploring the species diversity and protection of Osphya.

“…Despite proposing a new perspective that integrates bird richness and habitat quality to prioritize habitat restoration in hotspot areas, this study also has certain limitations. Firstly, data collection for biodiversity research inevitably faces the issue of uneven sampling [15]. The utilization of citizen-science data has expanded the spatiotemporal scale of bird pattern analysis, but it also suffers from the issue of observer subjectivity.…”

“…Previous studies have mainly considered birds or their habitats from a single perspective. Hotspot areas with a high prevalence of bird species play a crucial role in restoration and conservation efforts to preserve bird diversity [14,15]. For instance, Ruocheng et al [16] utilized citizen-science data and the Maxent model to assess hotspots of bird distribution and identify conservation gaps in China, thereby contributing to the formulation of habitat protection strategies.…”

Rapid global urbanization has caused habitat degradation and fragmentation, resulting in biodiversity loss and the homogenization of urban species. Birds play a crucial role as biodiversity indicators in urban environments, providing multiple ecosystem services and demonstrating sensitivity to changes in habitat. However, construction activities often disrupt urban bird habitats, leading to a decline in habitat quality. This paper proposes a framework for prioritizing habitat restoration by pinpointing bird hotspots that demand attention and considering the matching relationship between bird richness and habitat quality. Shanghai represents a typical example of the high-density megacities in China, posing a significant challenge for biodiversity conservation efforts. Utilizing the random forest (RF) model, bird richness patterns in central Shanghai were mapped, and bird hotspots were identified by calculating local spatial autocorrelation indices. From this, the habitat quality of hotspot areas was evaluated, and the restoration priority of bird habitats was determined by matching bird richness with habitat quality through z-score standardization. The results were as follows: (1) Outer-ring green spaces, large urban parks, and green areas along coasts or rivers were found to be the most important habitats for bird richness. Notably, forests emerged as a crucial habitat, with approximately 50.68% of the forested areas identified as hotspots. (2) Four habitat restoration types were identified. The high-bird-richness–low-habitat-quality area (HBR-LHQ), mainly consisting of grassland and urban construction land, was identified as a key priority for restoration due to its vulnerability to human activities. (3) The Landscape Shannon’s Diversity Index (SHDI) and Normalized Difference Vegetation Index (NDVI) are considered the most significant factors influencing the bird distribution. Our findings provide a scientifically effective framework for identifying habitat restoration priorities in high-density urban areas.

Climate change is expected to exert a large impact on the spatial distribution of insects, yet limited analyses are available for assessing the in uences of climate change on the distribution of Libellula angelina (Odonata: Libellulidae), which hindered the development of conservation strategies for this critically threatened dragon y species. Here, a consensus model (BIOCLIM, GAM, MaxEnt and Random Forest) and niche analysis approach were applied to predict the dynamic change of potential distribution areas and ecological niche for L. angelina under future climate change. Meanwhile, the important environmental variables affecting the potential distribution of L. angelina were identi ed. The results demonstrated that the potential distribution pattern and ecological niche of L. angelina will not shift signi cantly in face of future climate change, but its highly suitable area in southern Beijing (China), the western and southern South Korea, and the southern Honshu Island (Japan) will decrease constantly.Further analyses indicated that the human in uence index (32.3% of variation) is the second highest factor in predicting the potential distribution of L. angelina, following the precipitation of warmest quarter (42.6% of variation). Based on the obtained results, we suggest that extensive cooperation among the countries (China, South Korea and Japan) be advocated to formulate the international conservation strategies, especially more attention and conservation efforts should be paid in those high-suitability areas of L. angelina to gain better protection e ciency, and proper arti cial ecological restoration measures should also be exerted.Implication for insect conservation: Our results show that although the critically endangered dragon y L. angelina will still stay the current niche under climate change, its suitable area (especially highly suitable area) will decrease signi cantly. Therefore, we suggest that more attention and conservation efforts should be implemented in those high-suitability areas to reduce the extinction risk of L. angelina.
