| This study concerns the patterns of parasitism by the larvae of Eutrombicula alfreddugesi (Oudemans, 1910) on three species of Tropidurus Wied, 1820 from Cerrado habitats of Central Brazil: T. oreadicus Rodrigues, 1987 (n = 97), T. itambere (n = 85) and T. torquatus (Wied, 1820) (two samples n = 75, n = 23). The highest prevalence value was observed in T. itambere (88.2%), followed by T. oreadicus (87.6%), and T. torquatus (17.3% and 65.2%). The most important sites of infestation were the mite pockets and skin folds, especially on the neck and inguinal region. Tropidurus itambere Rodrigues, 1987 was the most heavily parasitized species (mean intensity of infestation: 36.67 ± 41.09), followed by T. oreadicus (15.38 ± 21.08), and T. torquatus from Unaí,... |

| In restinga areas of Marambaia, Rio de Janeiro, we recorded nine species of lizards, grouped in four families. The morphometric analysis suggested an invasion-structured pattern, with two distinct groups of species in the community: the "ground-runners", composed of animals with robust bodies and long limbs, represented by Tropidurus torquatus (Wied, 1820), Ameiva ameiva (Linnaeus, 1758), Liolaemus lutzae Mertens, 1938, Cnemidophorus littoralis Rocha, Araujo, Vrcibradic & Costa, 2000 and Tupinambis merianae (Duméril & Bibron, 1839); and the "hiders", composed of small-bodied animals with short limbs, represented by Hemidactylus mabouia (Moreau de Jonnès, 1818), Gymnodactylus darwinii (Gray, 1845), Mabuya agilis (Raddi, 1823) and M.... |

| We compared the effects of habitat disturbance on the feeding ecology of two local populations of Tropidurus torquatus (Wied, 1820) in restinga habitats on Ilha da Marambaia, Southeastern Brazil. Both populations presented a relatively diverse diet and differ in the number (D Max = 0.22, DF = 2, p = 0.00) and volume of prey consumed (D Max = 0.82, DF = 2, p = 0.00). Ants were the most frequent and numerous preys in both areas, and plant matter and coleopterans were the most important alimentary items in volume. The population from the disturbed area presented a larger niche breadth for number of prey items consumed (Bi num = 3.06) and volume (Bi vol = 2.98), when compared to the other population (Bj num = 2.44, Bj vol = 1.52). Niche overlap was higher for... |
