Patterns of native and exotic vascular plant richness along an elevational gradient from sea level to the summit of the Appalachian Mou...

Northeast (NE) China covers three climatic zones and contains all the major forest types of NE Asia. We sampled 108 forest plots in six nature reserves across NE China to examine the influence of climate and local factors (canopy seasonality, successional stage, topography and forest structure) on geographic patterns of plant richness. We analyzed the relative effects of different factors at tw...

Over the last decades, users have witnessed the growth and maturity of the Internet which has caused enormous growth in network traffic, driven by the rapid acceptance of broadband access, the increases in systems complexity, and the content richness. The over-evolving nature of the Internet brings new challenges in managing and delivering content to users, since for example, popular Web servic...

The debate about direct perception encompasses different topics, one of which concerns the richness of the contents of perceptual experiences. Can we directly perceive only low-level properties, like edges, colors etc. (the sparse-content view), or can we perceive high-level properties and entities as well (the liberal-content view)? The aim of the paper is to defend the claim that the content ...

BACKGROUND The Fynbos (FB) and Succulent Karoo biomes (SKB) have high regional plant diversity despite relatively low productivity. Local diversity in the region varies but is moderate. For insects, previous work suggests that strict phytophages, but not other taxa, may have high regional richness. However, what has yet to be investigated is whether the local insect species richness of FB and S...

autocorrelation and congruence in the distribution of language and mammal richness: a reply to Cardillo et al. Our paper on the relationship between the spatial distribution of language richness and mammal species richness recently argued that little congruence exists between the distribution of threatened languages and threatened mammals in New Guinea, despite high overlap between areas of hig...

The current trend of declining epiphytic richness caused by human activities (forest fragmentation, logging , agriculture, and livestock grazing) and the greater efforts required to sample and identify the most inconspicuous species have necessitated the use of indicators of the species richness. In this study, we examined the potential of predicting epiphytic lichen richness based on the richn...
