In order to analyze the abundance and distribution of mites in the lizard Liolaemus pictus and its relationship with the body size and sex of the host, 835 mites from 134 specimens of L. pictus captured in central Chile —Araucania Region to Los Lagos, including Chiloe Island— were studied. Prevalence, total abundance and abundance for each body region of the host were calculated. The relationship between the host body size and abundance of mites was analyzed. Mites were found in 39% of lizards… Expand

First identification of trombiculid mites (Acari: Trombiculidae) on rodents captured on Chiloé Island, an endemic region of scrub typhus in southern Chile
The presence of different rodent-associated chigger mites in a region with endemic scrub typhus in southern Chile suggests their role as vectors and reservoirs of this emerging zoonosis in South America. Expand
Chigger Mites (Acariformes: Trombiculidae) of Chiloé Island, Chile, With Descriptions of Two New Species and New Data on the Genus Herpetacarus
Abstract Three species of chigger mites are recorded in our collections from four species of cricetid rodents on Chiloé Island (southern Chile, Los Lagos Region), an area endemic to scrub typhusExpand
First record of the hard tick Amblyomma parvitarsum (Acari: Ixodidae) on the Liolaemus (Reptilia: Squamata) lizards from Peru
Larval and nymphal stages of A. parvitarsum parasitizing wild lizards of the genus Liolaemus in Peru are reported for the first time. Expand
General Ecology of Patagonian Lizards
The objective of this chapter is to present a synthesis of the current state of knowledge of the ecology of Patagonian lizards with regard to the use of spatial resources, temporal resources, and trophic resources. Expand


We studied the parasitism by the chigger mite Eutrombicula alfreddugesi on four sympatric lizard species of the genus Tropidurus in Morro do Chapéu, Bahia state, Brazil: T. hispidus, T. cocorobensis,Expand
Fragmented host distribution and trombiculid parasitic load: Eutrombicula araucanensis and Liolaemus pictus in Chile
The three distribution models evaluated in the present study were not adequate to represent the geographical structure of parasitic mites on L. pictus, and no association between the distance from the area of greatest species abundance and relative intensity, or association with the distance to the mite’s distribution centre was observed.

Pterygosomatidae and Trombiculidae mites infesting Tropidurus hispidus (Spix, 1825) (Tropiduridae) lizards in northeastern Brazil.
Parasitism of the lizard Tropidurus hispidus by Geckobiella sp. and by larvae of Eutrombicula alfreddugesi was examined in a mountainous area in Chapada do Araripe (07° 16' S and 39° 26' W), southernExpand
Patterns of parasitism by Eutrombicula alfreddugesi (Oudemans) (Acari, Trombiculidae) in three species of Tropidurus Wied (Squamata, Tropiduridae) from Cerrado habitat of Central Brazil
Differences in the patterns of parasitism among the three lizard species may be related to the morphological and numerical variation of the skin folds, to the degree of conservation of the host's habitats, and to selective processes related to reduction of damage to the hosts' bodies. Expand
Mites in the Neotropical Lizard Liolaemus pacha (Iguania: Liolaemidae): Relation to Body Size, Sex and Season
This study constitutes the second Argentine record of the presence of the ectoparasite Pterygosoma sp. Expand
Patterns of infestation by chigger mites in four diurnal lizard species from a Restinga habitat (Jurubatiba) of southeastern Brazil.
For all lizard species, the body parts where chiggers occurred with the highest intensity were those of skin folds and joint regions and only for C. littoralis did body size significantly affect the intensity of infestation. Expand
Infestación y distribución corporal de la nigua Eutrombicula alfreddugesi (Acari: trombiculidae) en el lacertilio de las rocas Sceloporus couchii (Sauria: phrynosomatidae)
There was not significant relationship among the snout-vent length, weight and the total number of acari in both sexes, probably indicating that this parasite does not influence the physical condition of this lizard. Expand
Abundance of Ticks (Acari: Ixodidae) Infesting the Western Fence Lizard, Sceloporus Occidentalis, in Relation to Environmental Factors
The impact of environmental characteristics, such as habitat type, topographic exposure and presence of leaf litter, on the abundance of Ixodes pacificus ticks infesting the western fence lizard at the University of California Hopland Research and Extension Center (HREC) is examined. Expand
Pterygosomatid mites of a new species group ligare (Acariformes: Pterygosomatidae: Pterygosoma) parasitizing tree iguanas (Squamata: Liolaemidae: Liolaemus).
A new species group, ligare, is established within the subgenus PteryGosoma (Acariformes: Pterygosomatidae: Perygosoma) based on an analysis of female morphology based on the presence of the movable cheliceral digit without a basal spur. Expand
Differential Parasitism by Sex on Plethodontid Salamanders and Histological Evidence for Structural Damage to the Nasolabial Groove
Histological examination of the nasolabial groove indicates that chigger attachment in the snout area can occlude the groove, and host tissue response and positioning of the chigger in the dermis was similar to that reported in other amphibian hosts. Expand
