Although some parasites have obvious pathogenic effects, others appear to have subtle, indirect effects that are poorly understood, particularly in natural populations. Indirect effects may result from parasites altering host metabolic rate and hence host energy needs, yet no experimental studies have shown this to be the case for non-laboratory hosts. We report the results of a long-term field experiment designed to test the impact of parasites on host energetics. We measured the energetics of… 

Figures and Tables from this paper

The energetic cost of parasitism in a wild population

It was found that flight costs were 10% higher in adult females with higher parasite loads and these individuals spent 44% less time flying than females with lower parasite loads, suggesting the existence of an energy ceiling.

Effects of parasites on host energy expenditure: the resting metabolic rate stalemate

It is concluded that a general understanding of parasite effects on host energetics may be best achieved through identifying mechanisms underlying among-system variance in para- site effects onHost RMR and relating parasite-associated perturbations of host energy budgets to robust estimates of host fit- ness.

The role of parasitism in the energy management of a free-ranging bird

Demonstration of the sub-lethal costs of endo-parasitism for a wild population of seabirds via increased maintenance metabolism and the use of an allocation energy management strategy, whereby an increase to RMR creates restrictions on energy allocation to other activities.

Parasites and Host Performance: Incorporating Infection into Our Understanding of Animal Movement.

How parasite infection can alter host locomotor performance via impacts on host morphology and physiology is reviewed and examples of behavioral strategies that some hosts employ to help overcome the disadvantages imposed by infection are given.

Energetic costs of parasitism in the Cape ground squirrel Xerus inauris

Impacts of parasites on host energy budgets are complex and are not easily explained by simple effects such as stimulation of a costly immune response, there is currently no broadly generalizable framework available for predicting the energetic consequences of parasitic infection.

Host resources govern the specificity of swiftlet lice: size matters

Comparing the relative fitness of host-specific lice experimentally transferred among closely related species of cave swiftlets in northern Borneo shows that adaptation to a particular resource on the body of the host does appear to govern the specificity of swiftlet lice.

The Energetic Cost of Parasitism in Isopods

This study demonstrates that infection with the acanthocephalan parasite Acanthocephalus tehlequahensis causes a significant and direct energetic cost to its freshwater isopod intermediate host Ceacidotea communis at both individual and population levels.

Reciprocal Natural Selection on Host‐Parasite Phenotypes

It is demonstrated that preening with a normal bill selects for small body size in lice, which may facilitate their escape from preening, which is a crucial element of coevolutionary theory.

Developmental, metabolic and immunological costs of flea infestation in the common vole

The experiment shows that infestation by a haematophageous parasite negatively affects multiple traits like growth, energy consumption and immune response, as well as the ability of voles to produce antibodies against a novel antigen.



Sublethal Parasites and Host Energy Budgets: Tapeworm Infection in White‐Footed Mice

It is found that infection by the tapeworm Hymenolepis citelli caused a 2% drop in dry- matter digestibility in host white-footed mice (Peromyscus leucopus), and no compensation for this decreased digestive efficiency was detected either in amount of food consumed or in mass change.

Effects of Plagiorhynchus cylindraceus (Acanthocephala) on the energy metabolism of adult starlings, sturnus vulgaris

These data indicate that, overall, male and female S. vulgaris respond differently to infection and that intestinal helminths normally thought to be of little or no pathological consequence to the host are factors that should be addressed in future studies regarding animal energetics, ecology, and behaviour.

Processes influencing the distribution of parasite numbers within host populations with special emphasis on parasite-induced host mortalities

It is shown that, for certain types of host–parasite associations, convex curves of mean parasite abundance in relation to age, concomitant with a decline in the degree of dispersion in the older age classes of hosts, may be evidence of the induction of host mortality by parasite infection.

Parasite-Host Associations : Coexistence or Conflict?

This chapter discusses the evolution of Host Specificity in Parasites with Complex Life Cycles and the Population and Community Consequences of Parasitism, and an Evolutionary Perspective: Using the Comparative Method.

Effects of Plasmodium relictum on the metabolic rate and body temperature in canaries (Serinus canarius).

There is no evidence that anti-,i chaintreated B-cell-suppressed mice suffer an exacerbated primary infection despite their inability to mount an antibody response, and the role of antibodies in controlling a primary infection alone is investigated.

Mate Choice in Experimentally Parasitized Rock Doves: Lousy Males Lose

A series of mate choice trials in which female Rock Doves were allowed to choose between “clean” males without lice and “lousy’ males with experimentally increased loads, finding that clean males displayed significantly more often than lousy males and females demonstrated a significant preference for clean males.

The ecology of ectoparasitic insects.

This book is the first to examine comprehensively the ecology of ectoparasitic insects and admits for review any group of organisms whose members follow the parasitic mode of life, emphasizing areas of parasitology which have advanced significantly at the time of publication.

Lizards infected with malaria: physiological and behavioral consequences.

There is a hierarchical relation between infection with malaria and effects on hematology, physiological function, and behavioral capacity, and the results suggest that malarial infection may have significant effects on the ecology of lizard hosts.


Either parasitism does not cause loss of body mass, or the techniques used were too insensitive to separate effects of parasitism from other natural causes.

Energy, calling, and selection

These factors constrain the ability of the animal to maximize energy received by the female, and two hypotheses, the good genes hypothesis and the runaway sexual selection hypothesis, are considered to explain the evolution of female choice for signals with greater energy content.
