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

Nature 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.

The species-area relationship and evolution [PDF]

Journal of Theoretical Biology, 2006
Models relating to the Species-Area curve are usually defined at the species level, and concerned only with ecological timescales. We examine an individual-based model of co-evolution on a spatial lattice based on the Tangled Nature model, and show that ...

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

PeerJ, 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.

Countryside species-area relationship as a valid alternative to the matrix-calibrated species-area model. [PDF]

Conserv Biol, 2014
Land-use change remains a major driver of biodiversity loss, and projecting extinction rates for different scenarios of habitat conversion is a key concern in conservation research (Pereira et al. 2010; Wright 2010; de Baan et al. 2013). Species–area relationships (SARs) have been one of the main models used to develop such projections, but they have ...

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

PLoS 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.

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

Ecosphere, 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

Global 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]

, 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 ...

Fragment size and the disassembling of local bird communities in the Atlantic Forest: A taxonomic and functional approach

Perspectives in Ecology and Conservation, 2020
Habitat loss is the primary driver of the decline of biodiversity in ecological communities. However, which ecological processes are implicated in the removal of species following habitat loss, i.e.

Lack of definition of mathematical terms in ecology: The case of the sigmoid class of functions in macro‐ecology

Ecology and Evolution, 2020
Defining mathematical terms and objects is a constant issue in ecology; often definitions are absent, erroneous, or imprecise. Through a bibliographic prospection, we show that this problem appears in macro‐ecology (biogeography and community ecology ...
