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 ...

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.

Environmental determinants of avian species richness in forests in a highly urbanized subtropical city: The effects of spatial scale and open space feature

open access: yesGlobal Ecology and Conservation, 2021
Numerous avian studies have emphasized the importance of natural/semi-natural elements, especially green spaces to conserve avian diversity in a city.

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.

Can species richness be maintained in logged endemic Acacia Heterophylla forests (Reunion Island, Indian Ocean) ? [PDF]

open access: yes, 2007
It is assumed that forests can serve multiple uses, including wood production and maintenance of high biodiversity level. We tested this hypothesis by studying eradication methods of invasive plants currently implemented in exploited endemic Acacia ...

Long-term species richness-abundance dynamics in relation to species departures and arrivals in wintering urban bird assemblages [PDF]

open access: yes, 2019
Temporal dynamics of local assemblages depend on the species richness and the total abundance of individuals as well as local departure and arrival rates of species. We used urban bird survey data collected from the same 31 study plots and methods during

Species richness, abundance and phenology of fungal fruit bodies over 21 years in a Swiss forest plot [PDF]

open access: yes, 2001
Fungal fruit bodies were surveyed on a plot area of 1500 m2 from 1975¿99 (excluding 1980¿83) in the fungal reserve La Chaneaz in western Switzerland. Fruit bodies were identified and counted on a weekly basis.

Unsaturated fish assemblages in rivers of the North-Western France : potential consequences for species introductions

open access: yesKnowledge and Management of Aquatic Ecosystems, 1997
Introductions of freshwater fish into French rivers have been carried out with increasing frequency in the last decades. Thus, the potential impact of these introductions is of major concern for biologists and fishery managers. Knowledge of the degree of

Energy Availability Factors Drive the Geographical Pattern of Tenebrionidae (Coleoptera) in the Arid and Semiarid Areas of China

open access: yesDiversity, 2022
Species richness is regarded as the core index of biogeography. Estimating the correlation between species richness and modern environmental factors will be of great significance for species conservation.

Determinants of species richness patterns in the Netherlands across multiple taxonomic groups [PDF]

open access: yes, 2009
We examined the species richness patterns of five different species groups (mosses, reptiles and amphibians, grasshoppers and crickets, dragonflies, and hoverflies) in the Netherlands (41,500 km2) using sampling units of 5 × 5 km. We compared the spatial
