Bats, Pathogens, and Species Richness [PDF]

open access: yesPathogens, 2021
Bats carry many viruses, but this is not sufficient to threaten humans. Viruses must mutate to generate the ability to transfer to humans. A key factor is the diversity of species.

Vascular plant species richness and bioindication predict multi‐taxon species richness [PDF]

open access: yesMethods in Ecology and Evolution, 2018
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. However, there is no consensus

Generalized Species Richness Indices for Diversity

open access: yesEntropy, 2022
A generalized notion of species richness is introduced. The generalization embeds the popular index of species richness on the boundary of a family of diversity indices each of which is the number of species in the community after a small proportion of ...

Quantifying biodiversity: procedures and pitfalls in the measurement and comparison of species richness [PDF]

open access: bronze, 2001
Species richness is a fundamental measurement of community and regional diversity, and it underlies many ecological models and conservation strategies.

Latitude, productivity and species richness [PDF]

open access: yesGlobal Ecology and Biogeography, 2015
Aim Global patterns in primary productivity in natural ecosystems are important for interpreting ecological processes and patterns of biodiversity. Net primary productivity (NPP) on land has long been thought to be greatest in tropical forests and to ...

Habitat fragmentation and species richness [PDF]

open access: yesJournal of Biogeography, 2015
AbstractIn a recent article in this journal, Fahrig (2013,Journal of Biogeography,40, 1649–1663) concludes that variation in species richness among sampling sites can be explained by the amount of habitat in the ‘local landscape’ around the sites, while the spatial configuration of habitat within the landscape makes little difference.

Evidence that species richness begets species richness

open access: yesJournal of Biogeography, 2023
The variability in regional species richness is determined by the balance between speciation, extinction, and migration, but the underlying causes of high species richness in some regions (e.g.

ANTS (Hymenoptera: Formicidae) WHICH WERE FOUND AT BENDOSARI PARK, SALATIGA

open access: yesAgric, 2021
In food chain of terrestrial ecosystem, ants have roles as predator of other arthropods, eater of seed, nectar, plant and aphid secreation, and fragmenter of dead organic matter.
