“…Recently, there have been many records of encysted juveniles of Centrorhynchus spp. in the body-cavity and gut-wall of various species of Anolis, mostly from the Caribbean Region (Acholonu, 1976;Dobson et al, 1992;Goldberg et al, 1994Goldberg et al, , 1997aGoldberg et al, , b, 1998. Unfortunately, the specimens were identified only to generic level (as Centrorhynchus sp.)…”

Seven species of Centrorhynchus Lühe, 1911 are present in the Parasitic Worms Collection of The Natural History Museum, London: C. aluconis (Müller, 1780) Lühe, 1911 from Strix aluco Linnaeus in Great Britain; C. buteonis (Schrank, 1788) Kostylev, 1914 from Accipiter virgatus (Temminck) (new host record) in Sri Lanka (new geographical record); C. clitorideus (Meyer, 1931) Golvan, 1956 from Athene brama (Temminck) (new host record) in India; C. crotophagicola Schmidt and Neiland, 1966 (encysted juveniles in the stomach wall) from Anolis lineatopus Grey (new host record) and A. sagrei Duméril and Bibron (new host record) from Jamaica (new geographical record); C. falconis (Johnston and Best, 1943) Golvan, 1956 from Spilornis cheela (Latham) in Sri Lanka (new geographical record); C. globocaudatus (Zeder, 1800) Lühe, 1911 from Falco ardosiaceus Vieillot (new host record) in West Africa; and C. milvus Ward, 1956 from Milvus migrans (Boddaert) in India. The species are described and figured on the basis of this material.

Fecally dispersed parasites of 12 wild mammal species in Mudumalai Sanctuary, southern India, were studied. Fecal propagule densities and parasite diversity measures were correlated with host ecological variables. Host species with higher predatory pressure had lower parasite loads and parasite diversity. Host body weight, home range, population density, gregariousness, and diet did not show predicted effects on parasite loads. Measures of a diversity were positively correlated with parasite abundance and were negatively correlated with f3 diversity. Based on these data, hypotheses regarding determinants of parasite community are discussed.Ecological studies on parasite communities of large mammals have been scanty (1) in contrast to those of other vertebrates (e.g., see refs. 2-8). For endangered mammals in protected areas, the only practical alternative to obtaining samples from culled individuals is fecal examination for parasite propagules (9), despite some limitations of this method (10). There have been few attempts to quantify measures of parasite abundance and diversity based on fecal analyses (11). It is also not clear what would be appropriate measures of species richness of parasite communities, and several indices have been used in the past (1,4,7,8,12). The issue is further complicated by different levels of community organization in parasite communities (13). Similarly, attempts to identify the host ecological factors involved in shaping parasite communities are few and only recent (3,(14)(15)(16).In this paper, we search for quantitative patterns in fecally dispersed parasites in a diverse community of mammalian hosts in Mudumalai Sanctuary, southern India. We first explore various measures of parasite diversity before going on to relate these to their mammalian host ecology. We consider the following host ecological factors that are likely to influence the parasite community.(i) Host population density: Since transmission increases with population density, both parasite loads and diversity are expected to be positively correlated with host density.(ii) Host body size and home range: A large host has higher intake of food and water and a larger home range, thus presumably sampling a higher parasite diversity (16,17 (vii) Predatory pressures: If predators kill highly parasitized prey individuals in higher proportion, then the infective foci will be continuously removed from the population of the prey species, resulting in reduced transmission. If even moderate parasite loads cause increased susceptibility to predation, then there will be greater selective pressure for parasite resistance. Hence, species with higher predatory pressures are expected to have lower parasite loads. MATERIALS AND METHODSStudy Area, Mammalian Hosts, and Parasite Sampling. The study was carried out in Mudumalai Sanctuary (11°32'N to 11°43'N and 76°22'E to 76°45'E; average elevation, 900 m above sea level) in southern India. Vegetation varies from tropical moist deciduous forest through dry deciduous forest to dry t...

“…In a study of helminths occurring in skinks from Papua New Guinea, which has an area of 41.48 million hectares (Marshall and Beehler 2006) mean endoparasite species diversity per skink species was 5.0 ± 3.3 SD, range 1-11 (Goldberg et al 2010). However, Dobson et al (1992) found no relationship between parasite density/abundance and island area for Anolis lizards in the northern Lesser Antilles. Sample size may be an important determinant; from Table 1, with the exception of the sample from Agrigan Island, helminths were not found when sample size was 20 individuals or less.…”

One hundred and ninety-eight Emoia caeruleocauda from nine of the Northern Mariana Islands, Micronesia were surveyed for helminths. Samples from Agrigan, Almagen, Anatahan, Asuncion, Pagan, Rota, Saipan, Sarigan and Tinian were examined. The helminth fauna was greatly depauperate: one species of Cestoda, Cylindrotaenia hickmani, one species of Nematoda, Skrjabinodon sheai and acanthocephalan cystacanths were found. Three of the larger islands, Agrigan, Rota and Saipan, contained two species of helminths. No helminths were found in E. caeruleocauda from Anatahan, Asuncion, Pagan and Tinian Islands.
