Null model approaches to evaluating the relative role of different assembly processes in shaping ecological communities

AS Mori, S Fujii, R Kitagawa, D Koide - Oecologia, 2015 - Springer
Various local processes simultaneously shape ecological assemblages. β-diversity is a
useful metric for inferring the underlying mechanisms of community assembly. However, β …

Generalism drives abundance: A computational causal discovery approach

C Song, BI Simmons, MJ Fortin… - PLOS Computational …, 2022 - journals.plos.org
A ubiquitous pattern in ecological systems is that more abundant species tend to be more
generalist; that is, they interact with more species or can occur in wider range of habitats …

How species richness and total abundance constrain the distribution of abundance

KJ Locey, EP White - Ecology letters, 2013 - Wiley Online Library
The species abundance distribution (SAD) is one of the most intensively studied
distributions in ecology and its hollow‐curve shape is one of ecology's most general …

Ecological response hides behind the species abundance distribution: Community response to low‐intensity disturbance in managed grasslands

A Komonen, M Elo - Ecology and Evolution, 2017 - Wiley Online Library
Land‐use and management are disturbance factors that have diverse effects on community
composition and structure. In traditional rural grasslands, such as meadows and pastures …

Direct evidence that density-dependent regulation underpins the temporal stability of abundant species in a diverse animal community

PA Henderson, AE Magurran - Proceedings of the …, 2014 - royalsocietypublishing.org
To understand how ecosystems are structured and stabilized, and to identify when
communities are at risk of damage or collapse, we need to know how the abundances of the …

Biogeographical patterns of species richness and abundance distribution in stream diatoms are driven by climate and water chemistry

SI Passy, CA Larson, A Jamoneau… - The American …, 2018 - journals.uchicago.edu
In this intercontinental study of stream diatoms, we asked three important but still unresolved
ecological questions:(1) What factors drive the biogeography of species richness and …

Function regression in ecology and evolution: FREE

JDL Yen, JR Thomson, DM Paganin… - Methods in Ecology …, 2015 - Wiley Online Library
Many questions in ecology and evolutionary biology consider response variables that are
functions (eg species‐abundance distributions) rather than a single scalar value (eg species …

Abundance inequality in freshwater communities has an ecological origin

SI Passy - The American Naturalist, 2016 - journals.uchicago.edu
The hollow-shaped species abundance distribution (SAD) and its allied rank abundance
distribution (RAD)—showing that abundance is unevenly distributed among species—are …

Disentangling the effects of sampling scale and size on the shape of species abundance distributions

RAF Lima, PA Conde, C Banks-Leite, RC Campos… - PLoS …, 2020 - journals.plos.org
Many authors have tried to explain the shape of the species abundance distribution (SAD).
Some of them have suggested that sampling spatial scale is an important factor shaping …
