Models and estimators linking individual-based and sample-based rarefaction, extrapolation and comparison of assemblages

TL;DR: In this paper, the authors provide new unconditional variance estimators for classical, individual-based rarefaction and for Coleman Rarefaction under two sampling models: sampling-theoretic predictors for the number of species in a larger sample (multinomial model), a larger area (Poisson model) or a larger number of sampling units (Bernoulli product model), based on an estimate of asymptotic species richness.
Journal ArticleDOI

Global Warming, Elevational Range Shifts, and Lowland Biotic Attrition in the Wet Tropics

TL;DR: It is concluded that tropical lowland biotas may face a level of net lowlandBiotic attrition without parallel at higher latitudes and that a high proportion of tropical species soon faces gaps between current and projected elevational ranges.
Journal ArticleDOI

Thermal-safety margins and the necessity of thermoregulatory behavior across latitude and elevation

TL;DR: It is found that most terrestrial ectotherms are insufficiently tolerant of high temperatures to survive the warmest potential body temperatures in exposed habitats and must therefore thermoregulate by using shade, burrows, or evaporative cooling and show why heat-tolerance limits are relatively invariant in comparison with cold limits.
Journal ArticleDOI

The ant fauna of a tropical rain forest: estimating species richness three different ways

TL;DR: In this paper, a thorough inventory of a tropical rain forest ant fauna and use it to evaluate species richness estimators is reported, which demonstrates that patterns of species occurrence early in an inventory may be inadequate to estimate species richness, but that relatively complete inventories of species-rich arthropod communities are possible if multiple sampling methods and extensive effort are applied.
Journal ArticleDOI

Biodiversity assessment using structured inventory: capturing the ant fauna of a tropical rain forest

TL;DR: A novel method of sample processing was developed, in which parataxonomists prepared specimens based on their own sorting of morphospecies within samples, and a taxonomic specialist later sorted the resultant pool of prepared specimens.
