Data from: Forest structure determines spatial changes in avian community along an elevational gradient in tropical Africa
Aim To test if tree species richness and forest structure drive spatial variation in avian communities along a tropical elevation gradient and to present information about the role of detailed forest parameters. Location A 2000-m long elevational gradient of tropical forest on Mt. Cameroon, west-central Africa. Taxon Birds and trees. Methods We performed bird censuses and vegetation mapping at the same plots across six forested sites at elevations of 350, 650, 1,100, 1,500, 1,850, and 2,200 m a.s.l., with 16 plots per elevation. We tested the effects of elevation, forest structure and tree diversity on the species richness, functional diversity and β-diversity of birds (Bray-Curtis dissimilarity). We used conditional inference trees based on random forests (RF) to investigate these relationships across all elevation sites as well as within elevations. Results Both tree and bird species richness declined monotonically with elevation. Vegetation structure correlated with elevation, and all vegetation attributes significantly differed among elevations. The RF explained 70% of the variance in avian species richness, with the most important predictors being elevation, proportion of dead trees, tree species richness and herb layer coverage. We found that elevation (and shrub layerE2) was a particularly important predictor of avian functional diversity. We identified no important predictor of bird species richness after standardization within elevations, and the proportion of dead trees was the sole important predictor of functional diversity. Within-elevation β-diversity in avian community composition was determined by the dissimilarity of the tree community and differences in leaf area index, solar radiation and spatial distance. The functional dissimilarity was best explained by leaf area index. Main conclusions Apart from elevation itself, spatial distance even within elevations correlated with compositional and functional variation among avian assemblages. Forest structural traits can have a significant influence on distribution of birds. Thus, gaps in the spatial distribution of species such as along elevations might be caused by fine-scale recognition of suitable habitats.
Elevation and landscape change drive the distribution of a montane, endemic grassland bird
<p>This dataset documents the presence and abundance of the Nilgiri pipit (<em>Anthus nilghiriensis</em>) in 170 survey sites across most of its global range. Between one and four surveys were carried out at each site between November 2017 and May 2018 by experienced observers. Survey duration was proportional to site area. A wide range of habitat characteristics were also surveyed, and additional habitat characteristics for each site were gathered from remotely sensed data. </p>
Data from: Changes in seed predation along a 2300-m elevational gradient on a tropical mountain in Myanmar: a standardized test with 32 non-native plant species
<p>It has been hypothesized that biotic interactions are stronger towards lower latitudes and elevations. However, results vary among interaction systems and experimental protocols. Our goal was to examine the validity of this prediction by using a standardized method to investigate seed–animal interaction. We assessed removal by animals for 40960 seeds belonging to 32 non-native tree species along an elevation gradient from 600 m to 2910 m on Mount Victoria (Nat Ma Taung), western Myanmar. We analyzed the elevational trends of seed removal at both individual seed level (probability of depot encounter, proportion of seeds removed after encounter and total proportion of seeds removed) and community level (Shannon diversity and species evenness indices). The dry and wet seasons had opposite relationships between seed removal and elevation,<br> i.e. hump-shaped in the dry season and U-shaped in the wet season. Individual plant species displayed almost all possible patterns: U-shaped and hump-shaped, monotonic decrease and increase, and elevation-independent patterns. As a consequence of the hump-shaped seed removal pattern with elevation in the dry season, the diversity and evenness of surviving seeds showed U-shaped patterns. Our study shows that elevational trends in seed–animal interactions do not follow a constant rule, but differ between seasons and among species, suggesting that a one-off survey with few species might give misleading information on overall macroecological patterns. Future studies of trends in biotic interactions along gradients should bear this in mind.</p>
Diversity and phylogenetic community structure across elevation during climate change in a family of hyperdiverse neotropical beetles (Staphylinidae)
<p>Environmental stress from abiotic conditions imposes physiological limits on individuals within communities, and these stressful conditions can act as a filter on the species present in any given environment. Such abiotic stressors can reduce a community's diversity and make its composition more phylogenetically clustered. Using a decade of staphylinid beetle (Staphylinidae, Coleoptera, rove beetles) collections made across a 1,500 m elevation gradient in northwestern Costa Rica (2008-2017) we asked what species lived there, how large and overlapping were the communities across this gradient, and what relationship was there between elevation and diversity. Using DNA barcodes for identification and phylogenetic estimates of community structure, we found high turnover across elevation, and that staphylinid diversity increased linearly with elevation. Because of this, we found staphylinid diversity was negatively related to surface area and temperature, and positively with precipitation. We suggest that historical biogeography and contemporary environmental stress have combined to produce these observed patterns. The forests in which these beetles are found are heating and drying rapidly and our finding that diversity increases with elevation suggests that there will be catastrophic biodiversity loss in the coming decades.</p>
