Data from: Habitat hotspots of common and rare tropical species along climatic and edaphic gradients
1. Understanding coexistence in high biodiversity ecosystems requires knowledge of how rare and common species share the multidimensional environmental space. Climatic and edaphic conditions can provide a plethora of habitats, supporting different compositional and structural communities where species can adapt and differentiate. 2. We used a large dataset consisting of 580 tropical tree species sampled in 163 25×25 m quadrats along an altitudinal gradient covering an area of 160 km2 of tropical rainforest in Jianfengling reserve (Hainan Island, China). For each plot the data include tree species and abundance, altitude and six soil properties from which a two dimensional environmental space was constructed. 3. With this extensive dataset we tested the hypothesis that different combination of environmental factors can generate multiple hotspots on three axes of diversity: species richness, Shannon-equivalent species richness and habitat preference, a measure of evenness in the distribution of individuals across an environmental gradient. 4. We found that humid and cool areas with more nitrogen availability were occupied by richer and more diverse communities of wide range species. Rare (in terms of number of individuals) and range restricted species instead, tended to prefer minor habitats, generally warmer with high potassium, calcium, magnesium and, in particular, phosphorous. As a result, wide and range restricted species were segregated across the environmental space. 5. Synthesis. Our findings indicate rare species tend to occur more frequently where common species are less abundant. A clear pattern of species richness and diversity was driven by a combination of several environmental factors (soil properties and climate). The complexity of the environment not only explains the different species distribution along each habitat, but also determines the relative abundance of each species in the entire community. Although some habitats have low species richness and diversity, they are highly preferred by rare species; therefore biodiversity conservation efforts should consider protecting these fragile ecosystems.
Data from: New species of Karydomys (Rodentia) from the Miocene of Chios Island (Greece) and phylogenetic relationships of this rare democricetodontine genus
Karydomys is a rare and little diversified democricetodontine, of which only six species are currently recognized. This group of rodents is first recorded in the early Miocene (MN3) in China and spread quickly thereafter to Kazakhstan and Greece (MN4). Karydomys reached south‐western and central Europe by early middle Miocene times (MN5), from where it became extinct shortly thereafter (MN6). A new species of Karydomys is here described from the Miocene Keramia Formation of Chios Island (north‐eastern Aegean Sea). Karydomys strati sp. nov. is characterized by the presence of a labial spur on the anterolophule, the lack of anterior protolophule on the M1 and by the presence of a double metalophule on the M2. A cladistics analysis involving all the species of Karydomys and some closely related species of Democricetodon and Cricetodon show that Karydomys split early into two different lineages, an 'eastern stock', which includes the central Asian (K. debruijni and K. dzerzhinskii) and Greek (K. symeonidisi, K. boskosi and K. strati) species, and a 'western lineage' comprising the western and central European species (K. wigharti and K. zapfei). The evolutionary stage of Karydomys strati suggests that the lowermost part of the Keramia Formation, usually attributed to the middle Miocene, is older than previously thought.
