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.

Species‐Area Relationship for Stream Fishes [PDF]

open access: yesEcology, 1989
We sampled riffles and pool habitats of small streams in Minnesota, Illinois, and Panama to examine variation in species—area relationships within and between the respective fish faunas. For six of the seven steams studies, habitat lume was a better predictor of species richness than was habitat area, and number of individuals was a better predictor of

Automated Discovery of Relationships, Models, and Principles in Ecology

open access: yesFrontiers in Ecology and Evolution, 2020
Ecological systems are the quintessential complex systems, involving numerous high-order interactions and non-linear relationships. The most used statistical modeling techniques can hardly accommodate the complexity of ecological patterns and processes ...

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.

Conservation Biogeography of Tenebrionid Beetles: Insights from Italian Reserves

open access: yesDiversity, 2020
The species-area relationship (SAR), the latitudinal gradient, the peninsula effect, and the elevational gradient are widespread biogeographical patterns.

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.

The Species–Area Relationship [PDF]

open access: yes, 2021
The species–area relationship (SAR) describes a range of related phenomena that are fundamental to the study of biogeography, macroecology and community ecology. While the subject of ongoing debate for a century, surprisingly, no previous book has focused specifically on the SAR.

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.
