SynopsisJuvenile three-spined sticklebacks,Gasterosteus aculeatus, were given a series of four ‘choice’ tests to determine whether they avoided schools of conspecifics in which individuals were parasitized with the ectoparasiteArgulus canadensis. Results from these tests indicate that juvenile sticklebacks can avoid schools of parasitized conspecifics. Furthermore, parasites alone did not elicit an avoidance response, suggesting that it is both the presence of the parasite and its effect on… 
Do microsporidian parasites affect courtship in two-spotted gobies?
TLDR
This study is one of the first to demonstrate a sub-lethal behavioural effect of a microsporidian parasite that could negatively affect the reproductive success of infected individuals and suggest that secondary sexual traits like courtship may be more sensitive to moderately detrimental effects of parasite infection than classical condition indices.
Adult Three-Spined Sticklebacks Prefer to Shoal with Familiar Kin
TLDR
Characteristics of the group such as measured by body mass, standard length, and body condition of its members did not significantly explain the shoaling preference for familiar kin, and it was indicated that adult, reproductively non-active sticklebacks prefer to shoal with familiar relatives.
Size‐assortative Schooling in Free‐ranging Sticklebacks
TLDR
The body-size distribution of individuals in schools of wild threespine stickleback, Gasterosteus aculeatus, was quantified, confirming the existence of size-assorted schools in the wild and suggesting that the phenotypic characteristics of individuals may be of importance when schools are formed.
Influence of black spot disease on shoaling behaviour in female western mosquitofish, Gambusia affinis (Poeciliidae, Teleostei)
TLDR
The results suggest that (1) the cost–benefit ratio of shoaling might be different for infected and non-infected individuals, and (2) Associating with infected conspecifics appears to be costly for female mosquitofish, maybe due to increased predation risk.
Cost and behavioural avoidance of trematode cercariae in fathead minnows
TLDR
Parasite-induced oxidative stress in liver tissue of fathead minnows exposed to trematode cercariae causes liver damage and cell death in animals exposed to these parasites.
Variation in occurrence of the fish-parasitic cymothoid isopod, Anilocra haemuli, infecting French grunt (Haemulon flavolineatum) in the north-eastern Caribbean
TLDR
This study provides the most comprehensive dataset for prevalence of any Anilocra spp.
Spatial dynamics in the social lobster Panulirus argus in response to diseased conspecifics
TLDR
Results showed that avoid- ance is driven by the chemoreception of cues based in the urine, and the chemical cue alone was as effective as having a diseased lobster present and visible.
Influence of parasitism on shoal choice in the banded killifish (Fundulus diaphanus, Teleostei, Cyprinodontidae)
TLDR
It is concluded that killifish preferred unparasitized shoals over parasitized Shoals only if all fish in the respective stimulus shoals were phenotypically uniform (either with or without black spots), and used black spots as an indicator of parasite presence to make their shoal choice.

Shoaling as an anti-ectoparasite mechanism in juvenile sticklebacks (Gasterosteus spp.)
TLDR
It is concluded that ectoparasitism may have been a strong selective factor in the evolution of social behaviour in juvenile sticklebacks.
Relationships between Bobwhite Quail Social-Group Size and Intestinal Helminth Parasitism
TLDR
It is argued that in the sedentary populations of northern Florida, young of the year may retain covey membership until the breeding season, and nonrandom associations between intensity and covey size for some parasitic helminths are found.
Water temperature, vertical distribution, and risk of ectoparasitism in juvenile sticklebacks
TLDR
The hypothesis that the risk of juvenile sticklebacks (Gasterosteidae) being parasitized by the crustacean ectoparasite Argulus canadensis decreases with increasing water temperature is tested and no significant effect of temperature is found.
Kin recognition and choice of shoal mates by threespine sticklebacks
TLDR
This study addressed five questions concerning kin recognition and shoaling in threespine stickleback Gasterosteus aculeatus fry and found the ability to discriminate sibs from non-sibs did not require experience and the strength of the shoaling preference was modified by events early in life.
ECTOPARASITISM AS A CAUSE OF NATAL DISPERSAL IN CLIFF SWALLOWS
TLDR
Nestling Cliff Swallows in southwestern Nebraska that were relatively heavily parasitized by hematophagous fleas and swal- low bugs dispersed to nonnatal colonies to breed the subsequent year, whereas nestlings that were comparatively lightly parasitized returned to their natal colony to breed.
Parasite load predicts mate choice in guppies
TLDR
In fish infected with Camallanus cotti or Gyrodactylus, females were found to prefer males with relatively few parasites, and this preference was associated with a higher display rate in less parasitised males.
The potential of parasitism in the structuring of a salt marsh stickleback community
TLDR
To determine if ectoparasites have the potential to play a role in structuring a salt marsh stickleback community, abundance of the copepod Thersitina gasterostei and fish louse Argulus canadensis was measured, and their effects on the condition and survival of juvenile fish were quantified.
ADVANTAGES AND DISADVANTAGES OF BANK SWALLOW (RIPARIA RIPARIA) COLONIALITY
TLDR
It is suggested that reduced predation on eggs and young, resulting from both gr ouLp defense and "selfish herd" effects, is an important advantage of Bank Swallow coloniality.
Group-living and infestation by ectoparasites in passerines
TLDR
It is suggested that individuals of group-living species incur a greater risk of acquiring contact-transmitted ectoparasites than individuals of solitary species, a cost which may not be negligible.
Female sticklebacks use male coloration in mate choice and hence avoid parasitized males
TLDR
It is shown that in the three-spined stickleback (Gasterosteus aculeatus) the intensity of male red breeding coloration positively correlates with physical condition, and the females recognize the formerly parasitized males by the lower intensity of theirbreeding coloration.
