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

open access: yesEcology 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 ...

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

open access: yesPerspectives 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.

Plot size matters: Toward comparable species richness estimates across plot‐based inventories

open access: yesEcology and Evolution, 2022
To understand the state and trends in biodiversity beyond the scope of monitoring programs, biodiversity indicators must be comparable across inventories. Species richness (SR) is one of the most widely used biodiversity indicators.

Determination of Optimal Sample Plot Dimension for Measuring Species Diversity of Plants in Beach Forest Ecosystem

open access: yesJurnal Ilmu Kehutanan, 2023
Biodiversity measurement served as baseline data for the development of effective conservation plans. The accuracy of the measurement was highly dependent on the size of the sample plot.

Would species richness estimators change the observed species area relationship? [PDF]

open access: yes, 2012
Copyright © 2008 Elsevier Masson SAS. All rights reserved.We evaluate whether the description of the species area relationship (SAR) can be improved by using richness estimates instead of observed richness values.

Species-occupancy distribution removes an excessive parameter from species-area relationship [PDF]

open access: yes, 2017
Aim Although species-occupancy distributions (SODs) and species-area relationships (SARs) arise from the two marginal sums of the same presence/absence matrices, the two biodiversity patterns are usually explored independently.

Ground Beetles of Islands in the Western Basin of Lake Erie and the Adjacent Mainland (Coleoptera: Carabidae, Including Cicindelini) [PDF]

open access: yes, 2017
We report 241 species representing 63 genera of ground beetles from the islands of the western basin of Lake Erie and selected mainland sites from a 1991-93 survey, plus specimens examined in public and private collections, and previously published ...

Relationships between hydraulic traits and habitat preference for six Acer species occurring in the French Alps [PDF]

open access: yes, 2004
Xylem hydraulic properties and vulnerability to cavitation were studied in six Acer species which occur, in the French Alps, along a soil moisture gradient from the moist valleys to the drier mountain stands.

The map of biodiversity: From local to global scales

open access: yesMètode Science Studies Journal: Annual Review, 2019
Species richness is not homogeneous in space and it normally presents differences when comparing among different sites. These differences often respond to gradients in one or several factors which create biodiversity patterns in space and are scale ...

Species-time-area and phylogenetic-time-area relationships in tropical tree communities [PDF]

open access: yes, 2013
The species-area relationship (SAR) has proven to be one of the few strong generalities in ecology. The temporal analog of the SAR, the species-time relationship (STR), has received considerably less attention.
