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 ...

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 ?”.

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 ...

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.

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.

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 ...

Estimating mutual information [PDF]

open access: yesPhysical Review E, 2004
We present two classes of improved estimators for mutual information $M(X,Y)$, from samples of random points distributed according to some joint probability density $ (x,y)$. In contrast to conventional estimators based on binnings, they are based on entropy estimates from $k$-nearest neighbour distances. This means that they are data efficient (with $

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.

Periodic Solutions of Multispecies Mutualism System with Infinite Delays

open access: yesAbstract and Applied Analysis, 2014
We studied the delayed periodic mutualism system with Gilpin-Ayala effect. Some new and interesting sufficient conditions are obtained to guarantee the existence of periodic solution for the multispecies mutualism system with infinite delays.

Mutual Submission, Mutual Respect

open access: yesStellenbosch Theological Journal, 2022
In Ephesians 5:21, Paul enjoins all Christians to live in mutual submission to each other out of reverence for Christ. In the verses that follow, Paul describes what this mutual submission should look like in practice. Some interpreters neglect the intimate connection which Eph 5:22–6:9 shares with the preceding verses in chapter 5.
