Fish Species Richness in Polish Lakes

open access: yesDiversity, 2023
Global warming, eutrophication, fisheries overexploitation, species invasions, and habitat loss are the major threats to freshwater biodiversity. The aim of this study was to determine the species richness and diversity of fish in 535 Polish lakes of ...

Global patterns and drivers of alpine plant species richness

open access: yesGlobal Ecology and Biogeography, 2021
Aim: Alpine ecosystems differ in area, macroenvironment and biogeographical history across the Earth, but the relationship between these factors and plant species richness is still unexplored. Here, we assess the global patterns of plant species richness

Global Patterns of Earwig Species Richness

open access: yesDiversity, 2022
One of the most investigated patterns in species diversity is the so-called latitudinal gradient, that is, a decrease in species richness from the equator to the poles.

Main predictors of periphyton species richness depend on adherence strategy and cell size. [PDF]

open access: yesPLoS ONE, 2017
Periphytic algae are important components of aquatic ecosystems. However, the factors driving periphyton species richness variation remain largely unexplored.

Modelling Species Richness and Functional Diversity in Tropical Dry Forests Using Multispectral Remotely Sensed and Topographic Data

open access: yesRemote Sensing, 2022
Efforts to assess and understand changes in plant diversity and ecosystem functioning focus on the analysis of taxonomic diversity. However, the resilience of ecosystems depends not only on species richness but also on the functions (responses and ...

Synchrony matters more than species richness in plant community stability at a global scale

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2020
Significance The stability of ecological communities under ongoing climate and land-use change is fundamental to the sustainable management of natural resources through its effect on critical ecosystem services.

Predicting microbial species richness [PDF]

open access: yesProceedings of the National Academy of Sciences, 2005
Microorganisms are spectacularly diverse phylogenetically, but available estimates of their species richness are vague and problematic. For example, for comparable environments, the estimated numbers of species range from a few dozen or hundreds to tens of thousands and even half a million.

A direct comparison of the effects and mechanisms between species richness and genotype richness in a dominant species on multiple ecosystem functions

open access: yesEcology and Evolution, 2021
Both species (interspecific) richness and genotype (intraspecific) richness of dominant species have significant effects on ecosystem functioning directly or indirectly by regulating plant community functional structure.

Urbanization and Human Population Favor Species Richness of Alien Birds

open access: yesDiversity, 2020
Human activities like urbanization and agriculture affect spatial biodiversity patterns. The presence and activities of humans richly benefit alien species, but native species usually decline in human-impacted areas.
