Individual variation evades the Prisoner's Dilemma [PDF]

open access: yes, 2002
Background The Prisoner's Dilemma (PD) is a widely used paradigm to study cooperation in evolutionary biology, as well as in fields as diverse as moral philosophy, sociology, economics and politics. Players are typically assumed to have fixed payoffs for

Mutualism benefits and the evolution of an interspecific sentry call in associations between Sociable Weavers and Fork-tailed Drongos [PDF]

open access: yes, 2013
Mutualisms, where organisms benefit from cooperation, are common in nature, but payoffs are dynamic and mutualists can incur costs as well as benefits from their association.

Studying Plant–Rhizobium Mutualism in the Biology Classroom

open access: yesThe American Biology Teacher, 2014
We present a guided-inquiry biology lesson, using the plant–rhizobium symbiosis as a model system. This system provides a rich environment for developing connections between the big ideas in biology as outlined in the College Board’s new AP Biology Curriculum.

Investigations into stability in the fig/ fig-wasp mutualism [PDF]

open access: yes, 2010
Fig trees (Ficus, Moraceae) and their pollinating wasps (Chalcidoidea, Agaonidae) are involved in an obligate mutualism where each partner relies on the other in order to reproduce: the pollinating fig wasps are a fig tree’s only pollen disperser ...

Caterpillars and fungal pathogens: two co-occurring parasites of an ant-plant mutualism [PDF]

open access: yes, 2011
In mutualisms, each interacting species obtains resources from its partner that it would obtain less efficiently if alone, and so derives a net fitness benefit.

BIOMEDICAL POTENTIAL OF ALGO-BACTERIAL SYMBIOSES

open access: yesЖурнал микробиологии, эпидемиологии и иммунобиологии, 2018
The analysis of the latest published works on the interactions between microalgae and bacteria is presented. Microalgae as a result of multimillion evolution can interact with each other and with another microorganisms.

Guest editorial: mutual relationship between vascular biology and hematology [PDF]

open access: yesInternational Journal of Hematology, 2012
Vascular biology has rapidly progressed in a molecular level since the identification of growth factors regulating blood vessel formation in the mid-1990s. In contrast to hematology, in which cytokines involved in the development and proliferation of hematopoietic cells (HCs) were first identified and analyzed in the 1980s, vascular biology has a short

The paradox of cooperation among selfish cancer cells

open access: yesEvolutionary Applications, 2023
It is traditionally assumed that during cancer development, tumor cells abort their initially cooperative behavior (i.e., cheat) in favor of evolutionary strategies designed solely to enhance their own fitness (i.e., a “selfish” life style) at the ...

Ants sow the seeds of global diversification in flowering plants [PDF]

open access: yes, 2009
Background: The extraordinary diversification of angiosperm plants in the Cretaceous and Tertiary periods has produced an estimated 250,000–300,000 living angiosperm species and has fundamentally altered terrestrial ecosystems.

Proximity ligation strategy for the genomic reconstruction of microbial communities associated with the ectoparasite Caligus rogercresseyi

open access: yesScientific Reports, 2022
The sea louse Caligus rogercresseyi has become one of the main constraints for the sustainable development of salmon aquaculture in Chile. Although this parasite's negative impacts are well recognized by the industry, some novel potential threats remain ...
