Stage-Specific Parasitism by a Mutualistic Partner Can Increase the Host Abundance

open access: yesFrontiers in Ecology and Evolution, 2020
Mutualism is one of the major interaction types occurring in ecological communities, and has significant consequences for population dynamics and community structure.

When to help juveniles, adults, or both: analyzing the evolutionary models of stage-structured mutualism

open access: yesFrontiers in Ecology and Evolution, 2023
Mutualism is common in nature and is crucial for population dynamics, community structure, and ecosystem functioning. Studies have recently pointed out that life-history stage structure (e.g., juveniles and adults) is a key factor to better understand ...

Changes in Population Dynamics in Mutualistic versus Pathogenic Viruses

open access: yesViruses, 2011
Although generally regarded as pathogens, viruses can also be mutualists. A number of examples of extreme mutualism (i.e., symbiogenesis) have been well studied.

Lagged effects of herbivory impact host‐choice but not nymphal survivorship in an ant‐protected treehopper

open access: yesEcosphere, 2022
Theoretical studies have shown that in protection mutualism, the modification of top‐down control by protectors may be destabilizing. Central to this prediction are the assumptions that (1) protection mutualism increases the abundance of protected ...

Mutual search

open access: yesJournal of the ACM, 1999
We introduce a search problem called “mutual search” where k agents, arbitrarily distributed over n sites, are required to locate one another by posing queries of the form “Anybody at site i ?”.

A meta‐analysis of the effects of climate change on the mutualism between plants and arbuscular mycorrhizal fungi

open access: yesEcology and Evolution, 2022
Climate change and other anthropogenic activities have the potential to alter the dynamics of resource exchange in the mutualistic symbiosis between plants and mycorrhizal fungi, potentially altering its stability.

Mutual Dimension

open access: yesACM Transactions on Computation Theory, 2015
We define the lower and upper mutual dimensions mdim ( x : y ) and Mdim ( x : y ) between any two points x and y in Euclidean space ...

The stability of mutualism [PDF]

open access: yesNature Communications, 2020
AbstractPositive interactions are observed at high frequencies in nearly all living systems, ranging from human and animal societies down to the scale of microbial organisms. However, historically, detailed ecological studies of mutualism have been relatively unrepresented.

Mutualism and adaptive divergence: co-invasion of a heterogeneous grassland by an exotic legume-rhizobium symbiosis. [PDF]

open access: yesPLoS ONE, 2011
Species interactions play a critical role in biological invasions. For example, exotic plant and microbe mutualists can facilitate each other's spread as they co-invade novel ranges.

Modéliser la croissance des populations mutualistes : une question scientifique complexe

open access: yesPhilosophia Scientiæ, 2011
The aim of this paper is an epistemological analysis of mutualism modeling. From the Lotka-Volterra analysis, we look for some characteristics and epistemological inadequacies of this class of models.
