Weighted species richness outperforms species richness as predictor of biotic resistance
Ecology, 2016AbstractThe species richness hypothesis, which predicts that species‐rich communities should be better at resisting invasions than species‐poor communities, has been empirically tested many times and is often poorly supported. In this study, we contrast the species richness hypothesis with four alternative hypotheses with the aim of finding better ...

The evolution of word use has contributed to the rich vocabulary of English in general and has made scientific English a particularly dynamic tool. However, some changes in word use have costs as well as benefits, and involve unintended consequences.

Summary A number of species richness estimators have been developed under the model that individuals (or sampling units) are sampled with replacement. However, if sampling is done without replacement so that no sampled unit can be repeatedly observed, then the traditional estimators for sampling with replacement tend to overestimate richness for ...

Predicting Parasitoid Species Richness
The American Naturalist, 1993We develop a formal theory, based on simple population dynamics constructs, to identify how proportional refuges to parasitism may act to determine the number of parasitoid species sampled per host species. A series of mathematical population models based on biologically realistic phenomena predict one of two basic species richness patterns.

Abstract One of the most famous features of tropical rain forests is their extreme species richness which has impressed scientists ever since the earliest explorations (Chapter 1). Some species are common, but most are rare: as has been described above (p.

Species richness maintains mutualisms
Science, 2020Ecology Mutualistic communities of species that benefit each other are ubiquitous in ecosystems and are important for ecosystem functioning. However, the relationship between the persistence of mutualisms and species richness has remained unclear. Vidal et al.

Historical biogeography, ecology and species richness
Trends in Ecology & Evolution, 2004Ecology and historical (phylogeny-based) biogeography have much to offer one another, but exchanges between these fields have been limited. Historical biogeography has become narrowly focused on using phylogenies to discover the history of geological connections among regions.

Species Richness and Diversity
2012This chapter reviews the literature on species richness and species diversity. The two concepts are closely related, but are not synonyms. Species richness is estimated dividing the number of species by the geographic area. On the other hand, species diversity is a function of the number of species present (i.e.

Sampling Effort and Parasite Species Richness
Parasitology Today, 1995Comparative studies of parasite species richness among host taxa can be confounded by uneven sampling effort. Sampling ceases to be a confounding factor when extrapolation methods are used to estimate true species richness. Here, Bruno Walther and colleagues review examples of sampling bias and the use of extrapolation methods for circumventing it ...

Variability in species richness and guild structure in two species-rich grasslands
Folia Geobotanica et Phytotaxonomica, 1995It has been suggested that variation in the proportion of species in guilds (=guild proportionality) indicates community structuring by guilds in biotic communities. This hypothesis was tested on a subthermophilous grassland and a mesotrophic meadow at a scale of 0.09 m2 based on a five-year data set.
