Prey Distribution as a Factor Determining the Choice of Optimal Foraging Strategy
TLDR
Whether the predator under observation actually behaves optimally in accordance with the distribution of prey should be revealed by plotting the number of captures against the length of period for which the predator stayed in each patch.
THE EVOLUTION OF COSTLY MATE PREFERENCES II. THE “HANDICAP” PRINCIPLE
TLDR
A general additive quantitative genetic model is used to study the evolution of costly female mate choice by the “handicap” principle and applies to other sources of fitness variation like migration and host‐parasite coevolution, which cause effects equivalent to biased mutation.
How should we define goodness?--reputation dynamics in indirect reciprocity.
THE EVOLUTION OF COSTLY MATE PREFERENCES I. FISHER AND BIASED MUTATION
TLDR
This analysis shows that evolutionary stable exaggeration of female preference can be achieved if mutation pressure on the male character is biased, that is, mutation has a directional effect at this equilibrium female fitness is not maximized.
Dynamics of chronic myeloid leukaemia
TLDR
A four-compartment model, based on the known biology of haematopoietic differentiation, can explain the kinetics of the molecular response to imatinib in a 169-patient data set and provides the first quantitative insights into the in vivoKinetics of a human cancer.
Influence of nonlinear incidence rates upon the behavior of SIRS epidemiological models
When the traditional assumption that the incidence rate is proportional to the product of the numbers of infectives and susceptibles is dropped, the SIRS model can exhibit qualitatively different…
Demographic Theory for an Open Marine Population with Space-Limited Recruitment
TLDR
A demographic model for a local population of sessile marine invertebrates that have a pelagic larval phase is introduced and suggests that two qualitatively distinct pictures of population structure result, depending on the settlement rate.
Pollen coupling of forest trees: forming synchronized and periodic reproduction out of chaos.
TLDR
A globally coupled map model in which trees accumulate photosynthate every year, produce flowers when the energy reserve level exceeds a threshold, and set seeds and fruits at a rate limited by pollen availability is analysed.
The leading eight: social norms that can maintain cooperation by indirect reciprocity.
Self-organization of the vascular system in plant leaves: inter-dependent dynamics of auxin flux and carrier proteins.
