Resource-based models of mutualism [PDF]

open access: yes, 2018
Mutualist interactions are thought to be ubiquitous, spanning all levels of biological organisation, and involving most species on Earth. However, in contrast to population interactions such as competition and predation, a comprehensive and succinct ...

Tipping Points in Seed Dispersal Mutualism Driven by Environmental Stochasticity [PDF]

open access: yes
The mechanism of seed dispersal mutualism is fundamental to understanding vegetation diversity and its conservation. In this study, we propose a stochastic model that extends the classical framework of seed dispersal mutualism to explore the effects of ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

An experimental and modelling exploration of the host-sanction hypothesis in legume-rhizobia mutualism [PDF]

open access: yes, 2008
Despite the importance of mutualism as a key ecological process, its persistence in nature is difficult to explain since the existence of exploitative, 'cheating' partners that could erode the interaction is common. By analogy with the proposed

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Interference Competition for Mutualism between Ant Species Mediates Ant-Mealybug Associations

open access: yesInsects, 2020
Ant-hemipteran mutualism has been well documented, and many studies have reported the interference competition between ant species for the mutualism.

Obligate mutualism in a resource-based framework

open access: yes, 2019
Obligate mutualist interactions appear to be ubiquitous in nature but cannot be described by the simple models that have been so effective for developing the theory of other population interactions including competition, predation, mixotrophy, and ...

Construction of bacteria–eukaryote synthetic mutualism [PDF]

open access: yes, 2013
Mutualism is ubiquitous in nature but is known to be intrinsically vulnerable with regard to both population dynamics and evolution. Synthetic ecology has indicated that it is feasible for organisms to establish novel mutualism merely through ...

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

The Neurobiology of Mutualistic Behavior: The Cleanerfish Swims into the Spotlight

open access: yesFrontiers in Behavioral Neuroscience, 2017
One of the most notorious examples of cooperation between different species happens in the cleaner-client fish mutualism. The best known cleaner fish species, the bluestreak Indo-Pacific cleaner wrasse Labroides dimidiatus has been a model system to ...
