“…A species distribution area reflects the variations in dispersal potential, ecological tolerance and historical evolution among various species [1]. The Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) established that the global surface temperature increased by 1.09 • C in 2011-2020 compared to 1850-1900.…”

Understanding species response to climate change is essential for the conservation and utilization of species resources under rapid climate change in the future. In this study, the present and future suitable distribution range of Keteleeria davidiana, a tertiary relict gymnosperm, was predicted based on the maximum entropy model (MaxEnt). A total of 158 occurrence records were collected after removing the duplicated records. Six low-correlation climate variables were used to predict species distributions. The three key climate factors that affect the distribution of K. davidiana were temperature seasonality (34.96%), mean temperature of the coldest quarter (28.30%) and precipitation seasonality (13.58%). The most suitable zone of the temperature seasonality for K. davidiana was between 377.4 and 843.4. The highly suitable area was located in the mountainous regions of central and southeast China, which accounted for 13.39% of the whole study area. With climate warming in the future, the highly suitable distribution area of K. davidiana was estimated to decrease by 35% (SSP1-2.6 scenario) or 85% (SSP5-8.5 scenario). This study has provided a sufficient scientific basis for the future in situ and ex situ conservation of K. davidiana.

“…This pattern occurred mainly due to limited sampling effort, constraints on species range boundaries, and geographical scales [ 13 , 63 ]. It is generally accepted that lower elevations have higher temperatures and precipitation, creating an environment that is more suited for many ectotherms, such as amphibians, and may sustain a broader variety of species and individuals [ 4 , 6 , 13 , 64 ]. At relatively higher elevations, there were drier streams in the nature reserve, and we speculate that this led to a decline in amphibian species that preferred wetter habitats, resulting in lower species diversity at higher elevations.…”

“…The species range is the maximum area and extent over which a species can be distributed spatially. It influences species differentiation and extinction and is an important ecological and evolutionary feature of species [ 16 , 64 ]. In our study, the PGLS analysis showed that the strong phylogenetic signal affected species range sizes and corresponding midpoints in amphibians.…”

Elevational gradients provide an excellent opportunity to assess biodiversity patterns and community structure. Previous studies mainly focus on higher elevations or are limited to small areas in mountainous regions. Little information can be found on amphibian biodiversity in middle- and low-elevational areas, hence our study was devoted to filling up the current gaps in these research areas. To understand the variability of biodiversity of amphibian species in the Fujian Junzifeng National Nature Reserve in eastern China, our study included taxonomic and phylogenetic components to describe the various patterns of regional and elevational distribution. The results showed that (1) most of the taxonomic and phylogenetic diversity metrics were correlated; with regard to the surveyed area, Faith’s phylogenetic diversity index (PD) and net relatedness index (NRI) were positively correlated with the Shannon–Wiener index (H’), Margalef index (DMG), and species richness (S), while negatively with the Pielou index; whereas for elevation, only the Pielou index was positively correlated with the nearest taxon index (NTI), but negatively with other indices; (2) taxonomic and phylogenetic diversities did not differ among the three survey locations but differed significantly along the elevational gradient; Simpson index, H’, S, and DMG had a hump-shaped relationship with elevations, and PD decreased gradually with the increase in elevation, whereas NRI and NTI sharply increased at the elevation above 900 m; (3) the species range size and the corresponding midpoint of amphibians were affected by a strong phylogenetic signal, which supports the elevational Rapoport’s rule upon removal of Pachytriton brevipes and Boulenophrys sanmingensis from the study.
