Species Richness Gradients
This chapter reviews the conceptual and methodological issues related to latitudinal and elevational gradients of species richness at distinct...

Map** density, diversity and species-richness of the Amazon tree flora
Using 2.046 botanically-inventoried tree plots across the largest tropical forest on Earth, we mapped tree species-diversity and tree...
-
Biodiversity time series are biased towards increasing species richness in changing environments
The discrepancy between global loss and local constant species richness has led to debates over data quality, systematic biases in monitoring...
-
Global patterns and predictors of primary freshwater crab richness across taxa and realms
Freshwater ecosystems are among the most important in the world and provide essential functions and services to humans. In this study, we examine the...

Richness, distribution, and endemism of neotropical subtribe Ponerinae (Orchidaceae, Epidendreae)
The subtribe Ponerinae (Orchidaceae) includes the genera Helleriella A. D. Hawkes, Isochilus R. Brown, Nemaconia Knowles & Westc., and Ponera Lindl....

Influence of canopy structural complexity on urban woodland butterfly species richness
As urban land use expands, understanding the conservation of biodiversity in urban settings becomes increasingly important. Urban areas contain a...
-
Species Richness and Beta Diversity Patterns of American Marsupials
Understanding the causes of spatial variation in biodiversity is a prominent issue in ecology and biogeography. Here, the species richness and the...
-
Connectivity of stormwater ponds impacts Odonata abundance and species richness
ContextThe successful dispersal of an animal depends, partly, on landscape connectivity. Urbanization poses risks to dispersal activities by...
-
Assessing the relation between geodiversity and species richness in mountain heaths and tundra landscapes
ContextRecent studies show that geodiversity—the diversity of Earth's landforms, materials, and processes—has a positive relationship with...
-
Lowland forest fragment characteristics and anthropogenic disturbances determine alien plant species richness and composition
Loss of habitat and biological invasion are the main threats to biodiversity. In intensive agricultural or urban landscapes, forest fragments, even...

Relationships Between Muskrat Density and Avian and Anuran Richness in Great Lakes Coastal Wetlands
Wetlands in southern Ontario are at risk of degradation and alteration due to human activities. This is a concern because wetlands provide essential...
-
Nested plot designs used in forest inventory do not accurately capture tree species richness in Southwestern European forests
Key messageNested plot designs with concentric plots with increasing radii and size threshold underestimate tree species richness with respect to...

Study of orchids (Orchidaceae) distribution and richness for conservation implications in Tripura, North East India
A total of 51 orchid species have been identified, in 105 locations of Tripura. Orchid species such as Acampe praemorsa , Aerides odoratum , Cymbidium...

Environmental drivers of species richness in shallow-water gorgonians (Cnidaria: Anthozoa) from the Eastern Tropical Pacific Ocean
Species richness, defined as the number of species within a specific area, exhibits spatial variation at most spatial scales. The drivers behind...

Earlier and more uniform spring green-up linked to lower insect richness and biomass in temperate forests
Urbanization and agricultural intensification are considered the main causes of recent insect decline in temperate Europe, while direct climate...
-
Pollinator abundance, not the richness, benefits from urban green spaces in intensive agricultural land
In the debate on the impact of urbanisation on biodiversity, two characteristics of urbanisation have been identified that mainly determine the...

Environmental thresholds for plant species richness of black alder (Alnus glutinosa) forests in Central Europe
The diversity of vascular plants in temperate floodplain forests varies between biogeographical regions of Europe. Our study aims to identify the key...
-
Predicting amphibian and reptile distributions and species richness across urban parks in the eastern United States
Urban parks and greenspaces protect biodiversity in cities and provide important opportunities for city residents to interact with wildlife. We used...
-
Synergistic effect of habitat loss and chronic anthropogenic disturbances on ant species richness
Habitat loss is an important factor in global biodiversity loss, but categorizing human-modified landscapes as fragments of natural or anthropogenic...
-
The effect of elevation, latitude, and plant richness on robustness of pollination networks at a global scale
Plant-pollinator interactions play a vital role in the maintenance of biodiversity and ecosystem function. Geographical variation in environmental...
