Vascular plant species richness and bioindication predict multi‐taxon species richness [PDF]
Methods in Ecology and Evolution, 2018 Abstract Plants regulate soils and microclimate, provide substrate for heterotrophic taxa, are easy to observe and identify and have a stable taxonomy, which strongly justifies their use as indicators in monitoring and conservation.

Estimating the Richness of a Population When the Maximum Number of Classes Is Fixed: A Nonparametric Solution to an Archaeological Problem [PDF]
, 2012 Background: Estimating assemblage species or class richness from samples remains a challenging, but essential, goal. Though a variety of statistical tools for estimating species or class richness have been developed, they are all singly-bounded: assuming

Latitudinal gradient in Gnomeskelus species richness [PDF]
Arthropods, 2020 The Tropical Conservativism Hypothesis suggests processes of speciation, extinction and dispersal resulted in higher species richness at the tropics and declined away from the equator. Biogeographical Conservativism Hypothesis suggests that the processes

Global Ecology and Conservation, 2020 Species richness is the core of biodiversity-ecosystem functioning (BEF) research. Nevertheless, it is difficult to accurately predict changes in plant species richness under different climate scenarios, especially in alpine biomes.

A Truncation Model for Estimating Species Richness [PDF]
The International Journal of Biostatistics, 2018 Abstract We propose a truncation model for the abundance distribution in species richness estimation. This model is inherently semiparametric and incorporates an unknown truncation threshold between rare and abundant observations. Using the conditional likelihood, we derive a class of estimators for the parameters in this model by ...

How do biodiversity patterns of river animals emerge from the distributions of common and rare species? [PDF]
, 2008 We studied the patterns of commonness and rarity for one vertebrate (fish) and four freshwater insect taxa (Ephemeroptera, Plecoptera, Trichoptera and Coleoptera) in southwestern France (57,000 km²), and we analysed the relationships between the location

Main predictors of periphyton species richness depend on adherence strategy and cell size.
PLoS ONE, 2017 Periphytic algae are important components of aquatic ecosystems. However, the factors driving periphyton species richness variation remain largely unexplored.

Frontiers in Ecology and Evolution, 2020 Despite the numerous studies on the large-scale patterns of species richness, the spatial variation and determinants of species richness for the alpine plants are still an outstanding question and critical to future biodiversity conservation.

Recovery of plant species richness during long-term fertilization of a species-rich grassland [PDF]
Ecology, 2011 Nutrient enrichment of habitats (eutrophication) is considered to be one of the main causes of plant diversity decline worldwide. Several experiments have shown a rapid loss of species in the first years after fertilization started. However, little is known about changes in species richness in the long term.

Does residence time affect responses of alien species richness to environmental and spatial processes? [PDF]
, 2012 One of the most robust emerging generalisations in invasion biology is that the probability of invasion increases with the time since introduction (residence time). We analysed the spatial distribution of alien vascular plant species in a region of north-
