A fitness cost of foraging in the guppy
Nature, 1988One hypothesized cost of foraging is an increased risk of mortality due to predation, which may result from greater conspicuousness and reduced vigilance for predators1–5. At high prey densities, a foraging animal must compromise vigilance to overcome the 'confusion effect'6,7 and achieve high feeding rates8,9.

Fitness costs associated with the acquisition of antibiotic resistance
Essays in Biochemistry, 2017Acquisition of antibiotic resistance is a relevant problem for human health. The selection and spread of antibiotic-resistant organisms not only compromise the treatment of infectious diseases, but also the implementation of different therapeutic procedures as organ transplantation, advanced surgery or chemotherapy, all of which require proficient ...

Fitness costs of gestation and lactation in wild mammals
Nature, 1989Like a number of plants, some mammals commonly produce more progeny than they can afford to rear, terminating investment in some or even all of their offspring once the resources available for breeding are known. Adaptive interpretations of juvenile wastage rely on the argument that the costs of gestation are small compared to those of feeding ...

Herbivory eliminates fitness costs of mutualism exploiters
New Phytologist, 2014Summary A common empirical observation in mutualistic interactions is the persistence of variation in partner quality and, in particular, the persistence of exploitative phenotypes. For mutualisms between hosts and symbionts, most mutualism theory assumes that exploiters always impose fitness costs on their host.

A cost term in an evolutionary robotics fitness function
Proceedings of the 2000 Congress on Evolutionary Computation. CEC00 (Cat. No.00TH8512), 2002In order to address the domain of more complex robots and problems, robot controllers and robot structures will need to be co-evolved. To achieve the goal of the automated design of complex robotics systems and their associated control programs, a method for managing the complexity of the solution during evolution is needed.

Crouching to fit in: the energetic cost of locomotion in tunnels
Journal of Experimental Biology, 2016Animals that are specialized for a particular habitat or mode of locomotion often demonstrate locomotor efficiency in a focal environment when compared to a generalist species. However, measurements of these focal habitats or behaviors are often difficult or impossible to do in the field. In this study, the energetics and kinematics of simulated tunnel
