Aims: Elevational gradients of fern species richness in tropical forest habitats were analysed to test the hypotheses that fern species composition patterns were similar between elevational gradients, that total species richness of complete elevational gradients gradually declined due to changing climatic conditions with increasing distance from the Equator, and that the elevation of highest species richness gradually declined with increasing latitude. Methods: We used plot-based elevational fern species richness surveys compiled from recent field work and own published studies, between 18 degrees N and 18 degrees S along the Andean mountain range, and compared the transects of patterns of species richness and composition, and distribution of taxa. Results: Taxonomic composition was highly similar among tropical regions. Elevational richness patterns were symmetrically hump-shaped and overall richness was virtually equal along most of the tropical latitudinal gradient. In contrast, the subtropical localities at the edges of our study area, ca. 18 degrees N and 18 degrees S, showed strikingly different patterns from those in the tropical zone. Conclusions: Within the tropics, there appears to be no latitudinal diversity gradient of ferns at the local scale. We suggest that, in tropical habitats, species richness of ferns at the local scale is limited by the number of species that can co-occur and that the available niche space is saturated."],["dc.description.sponsorship","Schweizer Nationalfonds (SNF); German Academic Exchange Service (DAAD)"],["dc.identifier.doi","10.1080/17550874.2013.843036"],["dc.identifier.isi","000349391300002"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/38214"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Taylor & Francis Ltd"],["dc.relation.issn","1755-1668"],["dc.relation.issn","1755-0874"],["dc.title","Diversity patterns of ferns along elevational gradients in Andean tropical forests"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

Few studies have produced the necessary comprehensive data sets to assess the quality of the indicator groups, however, and only one previous study has considered the monetary costs involved in sampling them.2. We surveyed four plant groups (herbs, liverworts, trees, lianas) and eight animal groups (ants, canopy and dung beetles, birds, butterflies, bees, wasps and the parasitoids of the latter two) in 15 plots of 50 × 50 m2 each, representing undisturbed rainforest and two types of cacao agroforest in Sulawesi, Indonesia. We calculated three biodiversity measures (α and β diversity; percentage of species indicative of habitat conditions), built simple and multiple regression models among species groups (single groups, combinations of 2–11 groups, averaged relative diversity of all 12 groups), and related these to three measures of survey cost (absolute costs and two approaches correcting for different sampling intensities).3. Determination coefficients (R2 values) of diversity patterns between single study groups were generally low (<0·25), while the consideration of several study groups increased R2 values to up to 0·8 for combinations of four groups, and to almost 1·0 for combinations of 11 groups. Survey costs varied 10-fold between study groups, but their cost-effectiveness (indicator potential versus monetary cost) varied strongly depending on the biodiversity aspect taken into account (α or β diversity, single or multiple groups, etc.).4. Synthesis and applications. We found that increasing the number of taxa resulted in best overall biodiversity indication. We thus propose that the most cost-efficient approach to general tropical biodiversity inventories is to increase taxonomic coverage by selecting taxa with the lowest survey costs."],["dc.identifier.doi","10.1111/j.1365-2664.2010.01932.x"],["dc.identifier.gro","3150082"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6811"],["dc.language.iso","en"],["dc.notes.status","public"],["dc.relation.issn","0021-8901"],["dc.title","Cost-effectiveness of plant and animal biodiversity indicators in tropical forest and agroforest habitats"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dspace.entity.type","Publication"]]

Among them, however, air humidity is notoriously difficult and time-consuming to measure, and it has been proposed that the epiphytic bryophyte cover can be used as an indicator of long-term air humidity conditions. Here we explore the utility of visually estimated epiphytic bryophyte cover on large canopy branches as a proxy for air humidity at 26 study sites in tropical forests where we measured microclimate for at least 12 months. Across all sites, bryophyte cover was weakly related to relative air humidity (R-2 = 0.17), but when we separated highland (1800-3500 m elevation) from lowland (<1800m) sites, relative air humidity showed significant and distinct relations to bryophyte cover (R-2 = 0.36-0.62), whereas temperature was related to bryophyte cover only in the lowlands (R-2 = 0.36). We conclude that epiphytic bryophyte cover can be used as a proxy for air humidity if temperature and elevation are taken into account within a circumscribed study region, but might not be applicable for comparisons across extensive elevational gradients or wide differences in temperature.
