Host plant use by competing acacia-ants : mutualists monopolize while parasites share hosts [PDF]

open access: yes, 2012
Protective ant-plant mutualisms that are exploited by non-defending parasitic ants represent prominent model systems for ecology and evolutionary biology.

Joint evolution of kin recognition and cooperation in spatially structured rhizobium populations.

open access: yesPLoS ONE, 2014
In the face of costs, cooperative interactions maintained over evolutionary time present a central question in biology. What forces maintain this cooperation? Two potential ways to explain this problem are spatially structured environments (kin selection)

Interactions Between Figs and Gall-Inducing Fig Wasps: Adaptations, Constraints, and Unanswered Questions

open access: yesFrontiers in Ecology and Evolution, 2021
The ancient interaction between figs (Ficus, Moraceae) and their pollinating fig wasps is an unusual example of a mutualism between plants and gall-inducing insects.

The expression of stlA in Photorhabdus luminescens is controlled by nutrient limitation [PDF]

open access: yes, 2013
Photorhabdus is a genus of Gram-negative entomopathogenic bacteria that also maintain a mutualistic association with nematodes from the family Heterorhabditis.

Endolichenic fungi: the lesser known fungal associates of lichens

open access: yesMycology, 2017
Lichens are the result of a stable mutualism between a fungal and a photosynthesising partner (alga or cyanobacterium). In addition to the fungal partner in this mutualism, lichens are associated with endolichenic fungi which reside inside their thalli ...

Towards the development of sustainable control options for the African root and tuber scale on cassava in Central Africa : understanding the biology and ecology of the tending ant "Anoplolepis tenella" (Hymenoptera: Formicidae) [PDF]

open access: yes, 2011
Anoplolepis tenella Santschi is an afrotropical ant widely distributed in the forest zones of Central Africa. It is the most frequent species associated with the African root and tuber scale (ARTS) Stictococcus vayssierei (Hemiptera: Stictococcidae), an ...

A Mixed Self: The Role of Symbiosis in Development [PDF]

open access: yes, 2011
Since the 1950s, the common view of development has been internalist: development is seen as the result of the unfolding of potentialities already present in the egg cell. In this paper I show that this view is incorrect, because of the crucial influence

Temporal Structure in Cooperative Interactions: What Does the Timing of Exploitation Tell Us about Its Cost? [PDF]

open access: yesPLoS Biology, 2016
Exploitation in cooperative interactions both within and between species is widespread. Although it is assumed to be costly to be exploited, mechanisms to control exploitation are surprisingly rare, making the persistence of cooperation a fundamental ...
