Control of ecological networks: Abundance control or ecological regulation?
Chaos: An Interdisciplinary Journal of Nonlinear ScienceComplex ecosystems often exhibit a tipping point around which a small perturbation can lead to the loss of the basic functionality of ecosystems. It is challenging to develop a control strategy to bring ecosystems to the desired stable states. Typically, two methods are employed to restore the functionality of ecosystems: abundance control and ...

Atmospheric Microplastics: Perspectives on Origin, Abundances, Ecological and Health Risks
Environmental Science and Pollution Research, 2023Microplastic (MP) pollution has aroused a tremendous amount of public and scientific interest worldwide. MPs are found widely ranging from terrestrial to aquatic ecosystems primarily due to the over-exploitation of plastic products and unscientific disposal of plastic waste.

Exploitative competition and ecological effective abundance
Ecological Modelling, 1997Abstract This study analyzes the effect of exploitative competition and density dependence by using an individual-based simulation model. There are two components of exploitative competition (leftovers and resource-recovery competition). In leftovers competition, individuals compete for food resources that have been left by others.

1978
As we mentioned in Section 1.1. there can be little doubt that ecology was responsible for the development of the theory of diversity and that it is still the main field of application. Throughout this chapter, the classes C1,C2,…,C S refer to the various species of some taxonomic group of animals or plants.

Abundance models in ecology—examples
1978A generating process In Chapter 2 we made some general assumptions concerning the distribution of X = (X1,X2,…,XS) stating that the probability generating function of X was $$ {{G}_{x}}\left( z \right) = {{M}_{v}}\left( {\Sigma {{p}_{i}}{{z}_{i}} - 1} \right), $$ where Mv( ) denotes some moment-generating function.

Abundance Inequality in Freshwater Communities Has an Ecological Origin
The American Naturalist, 2016The hollow-shaped species abundance distribution (SAD) and its allied rank abundance distribution (RAD)-showing that abundance is unevenly distributed among species-are some of the most studied patterns in ecology. To explain the nature of abundance inequality, I developed a novel framework identifying environmental favorability, which controls the ...

Abundance and feeding ecology of Antarctic phaeodarian radiolarians
Marine Biology, 1989Phaeodarian radiolarians were sampled from the upper 200 m along a transect through the ice-edge zone in the Weddell Sea in the austral autumn (March 1986) and at several stations in the western Antarctic Peninsula region in the austral winter (June 1987).

Simple and robust models of ecological abundance
1. Counts of species in ecological samples are of interest when they tell us about community assembly processes. Older process-based models of count distributions are either complex, widely rejected, or not able to predict high unevenness. 2. I leverage a general strategy for deriving simple one-parameter models.openaire +1 more source
