An empirical evaluation of four variants of a universal species-area relationship. [PDF]

open access: yesPeerJ, 2013
The Maximum Entropy Theory of Ecology (METE) predicts a universal species-area relationship (SAR) that can be fully characterized using only the total abundance (N) and species richness (S) at a single spatial scale.

Modelling the species-area relationship using extreme value theory [PDF]

open access: yesNature Communications
The nested species-area relationship, obtained by counting species in increasingly larger areas in a nested fashion, exhibits robust and recurring qualitative and quantitative patterns.

A generalized approach to the modeling of the species-area relationship. [PDF]

open access: yesPLoS ONE, 2014
This paper proposes a statistical generalized species-area model (GSAM) to represent various patterns of species-area relationship (SAR), which is one of the fundamental patterns in ecology.

Applicability of Common Algorithms in Species–Area Relationship Model Fitting

open access: yesDiversity, 2022
The species–area relationship (SAR) describes a law of species richness changes as the sampling area varies. SAR has been studied for more than 100 years and is of great significance in the fields of biogeography, population ecology, and conservation ...

Floristic Richness in a Mediterranean Hotspot: A Journey across Italy

open access: yesPlants, 2023
Species richness is a fundamental property of biodiversity patterns and is properly expressed by the species–area relationship (SAR), namely the increase in the number of species with the area.

Hummingbird–Plant Interactions Are More Specialized in Forest Compared to Coffee Plantations

open access: yesDiversity, 2020
Deforestation transforms habitats, displacing vertebrates and the other dimensions of biodiversity they support through their interactions. Few empirical studies have quantified the effect deforestation has on vertebrate–pollinator interaction networks ...

Toward a unified diversity–area relationship (DAR) of species and gene diversity illustrated with the human gut metagenome

open access: yesEcosphere, 2021
The biogeographic diversity of the microbiome can be investigated from two perspectives: the spatiotemporal distribution of species (or any operational taxonomic unit) diversity and the spatiotemporal distribution of metagenomic gene diversity. Together,

Structure, growth, and sustainability of mangrove forests of mainland Tanzania

open access: yesGlobal Ecology and Conservation, 2020
Mangrove forests provide a range of ecosystem services, which are important for the well-being of humankind. Hence, they need to be managed sustainably. Datasets on forest structure, relationships between structural parameters as well as growth and yield

Marked decline in forest-dependent small mammals following habitat loss and fragmentation in an Amazonian deforestation frontier [PDF]

open access: yes, 2020
Agricultural frontier expansion into the Amazon over the last four decades has created million hectares of fragmented forests. While many species undergo local extinctions within remaining forest patches, this may be compensated by native species from ...

Beetle Species–Area Relationships and Extinction Rates in Protected Areas

open access: yesInsects, 2020
The species–area relationship (SAR, i.e., the increase in species richness with area) is one of the most general ecological patterns. SARs can be used to calculate expected extinction rates following area (habitat) loss.
