Avian mobbing: byproduct mutualism not reciprocal altruism.

performance of the methods [3]. There is a place for different approaches to reflect the diversity of data and hypotheses being addressed, but it is important that supertree workers justify their choice of method. MRP remains popular largely because of its convenience (as standard phylogenetic software is used to analyse the transformed data), but relying exclusively upon MRP is increasingly di...

Costly Financial Intermediation and Relative Consumption Volatility

This paper proposes a model that emphasizes housing market interactions and …nancial intermediation costs to explain relative consumption volatility di¤erences between developed and emerging countries. The model improves upon existing dynamic stochastic general equilibrium (DSGE) models by incorporating a non-trivial …nancial sector and by letting both households and …rms face borrowing constra...

Evolution of mutualism through spatial effects.

Mutualism among species is ubiquitous in natural ecosystems but its evolution is not well understood. We provided a simple lattice model to clarify the importance of spatial structure for the evolution of mutualism. We assumed reproductive rates of two species are modified through interaction between species and examine conditions where mutualists of both species, that give some benefit to the ...

The evolution of mutualism with modifiers

Mutualisms are widespread, yet their evolution has received less theoretical attention than within-species social behaviors. Here, we extend previous models of unconditional pairwise interspecies social behavior, to consider selection for donation but also for donation-suppressing modifiers. We present conditions under which modifiers that suppress costly donation receive either positive or neg...

The evolution of costly acquired immune memory

A key feature of the vertebrate adaptive immune system is acquired immune memory, whereby hosts launch a faster and heightened response when challenged by previously encountered pathogens, preventing full infection. Here, we use a mathematical model to explore the role of ecological and epidemiological processes in shaping selection for costly acquired immune memory. Applying the framework of a...
