contribution of collagen stable isotope biogeochemistry to the paleobiology of extinct endemic vertebrates from tenerife (canary islands, spain).the paleodiet and paleoenvironmental context of two extinct species from tenerife island, one giant rat canariomys bravoi and one giant lizard gallotia goliath, have been investigated using carbon and nitrogen isotopic compositions of fossil bone collagen. preliminary to this study, a calibration of the isotopic variations of bone collagen from modern rat rattus rattus, rabbit oryctolagus cuniculus and lizard gallotia galotti relative to environmental conditions on tenerife islands has been atte ...200314521281
finding of parastrongylus cantonensis (chen, 1935) in rattus rattus in tenerife, canary islands (spain).parastrongylus cantonensis is a parasite of murid rodents that can infect humans and cause health problems as eosinophilic meningitis. although it is endemic in south asia, the pacific islands, australia, usa, and a few caribbean islands, it has been extended to new geographical regions. in the canary islands (spain) a survey of helminths of rattus rattus, rattus norvegicus and mus musculus domesticus was carried out. furthermore, five species of molluscs were examined for nematode larvae to det ...201020153283
distribution and genetic variation of hymenolepidid cestodes in murid rodents on the canary islands (spain).in the canary islands there are no previous data about tapeworms (cestoda) of rodents. in order to identify the hymenolepidid species present in these hosts, a survey of 1,017 murine (349 rattus rattus, 13 rattus norvegicus and 655 mus musculus domesticus) was carried out in the whole archipelago. molecular studies based on nuclear its1 and mitochondrial coi loci were performed to confirm the identifications and to analyse the levels of genetic variation and differentiation.201121943096
seroprevalence of angiostrongylus cantonensis in wild rodents from the canary islands.angiostrongylus cantonensis is a lungworm of rats (muridae) that is the causative agent of human cerebral angiostrongyliasis. the life cycle of a. cantonensis involves rats and mollusks as the definitive and intermediate hosts, respectively. this study was designed to increase the knowledge about the occurrence and distribution of a. cantonensis in its definitive host in the canary islands, using parasitological and serological analysis in different areas and age groups.201122110752
serological survey of antibodies to toxoplasma gondii and coxiella burnetii in rodents in north-western african islands (canary islands and cape verde).coxiella burnetii and toxoplasma gondii are intracellular parasites that cause important reproductive disorders in animals and humans worldwide, resulting in high economic losses. the aim of the present study was to analyse the possible role of peridomestic small mammals in the maintenance and transmission of c. burnetii and t. gondii in the north-western african archipelagos of the canary islands and cape verde, where these species are commonly found affecting humans and farm animals. between 2 ...201526244685
parasite fauna of rodents (murinae) from el hierro (canary islands, spain): a multidisciplinary approach.the parasite fauna (protozoa, helminths and insects) of the two most widespread murinae rodents in el hierro (canary islands, spain), the black rat (rattus rattus) and the house mouse (mus musculus domesticus) was studied. faunistic, ecological, ecotoxicological data, as well as information on the biology of some nematode parasites of r. rattus are provided. the present work is unprecedented in the canary islands, and provides the first data on the parasite biodiversity in murinae from the archi ...201222807054
presence of stenoponia tripectinata (tiraboschi, 1902) (siphonaptera, ctenophtalmidae) in murine (rodentia) from the canary islands.this article reports the geographical and host distribution of the flea stenoponia tripectinata on the canary islands. s. tripectinata is widely distributed throughout the mediterranean and north africa as a parasite of muridae rodents. to date, gran canaria is the only island of the archipelago where s. tripectinata had been found. in this report, s. tripectinata has appeared parasitizing 116 specimens of mus musculus out of a total of 660, and only 2 rattus rattus of 215 captured. all the trap ...201222807056
xenopsylla spp. (siphonaptera: pulicidae) in murid rodents from the canary islands: an update.the geographical and host distributions of xenopsylla fleas parasitizing murid rodents on the canary islands have been reported. three xenopsylla species, x. cheopis, x. brasiliensis and x. guancha, have been detected on two rodents species, mus musculus and rattus rattus. x. guancha has been the most prevalent species detected, specifically on m. musculus, the most abundant rodent, but it has been detected only on three eastern islands, where the species is endemic. x. cheopis has been shown to ...201223193528
positive co-occurrence of flea infestation at a low biological cost in two rodent hosts in the canary archipelago.non-random assemblages have been described as a common pattern of flea co-occurrence across mainland host species. however, to date, patterns of flea co-occurrence on islands are unknown. the present work investigates, on one hand, whether the decrease in the number of species on islands affects the pattern of flea co-occurrence, and on the other hand, how the cost of higher flea burdens affects host body mass. the study was carried out in the canary islands (spain) using null models to analyse ...201424476922
on the biology of spiruroidea parasites of murine rodents on el hierro (canary islands, spain) with molecular characterization of streptopharagus greenbergi wertheim, 1993.this paper reports the role of darkling beetles pimelia laevigata costipennis and hegeter amaroides (tenebrionidae) as intermediate hosts of spiruroid nematodes parasites of the black rat and house mouse of el hierro (canary islands). larvae of spiruroid species were found in the two tenebrionids (18.1% in p. l. costipennis, 7.8% in h. amaroides), streptopharagus greenbergi being predominant in both (16.1% and 7.1%, respectively), ahead of mastophorus muris and gongylonema type larva. the larval ...201324161241
the role of wild rodents in the transmission of trypanosoma evansi infection in an endemic area of the canary islands (spain).trypanosoma evansi was diagnosed for the first time in camels in the canary islands in 1997. several sanitary measures including treatment of infected animals were taken; however, nowadays a little area is still infected. in order to determine possible reservoirs 138 wild rodents were trapped, 64 of them in the infected farms and the remaining 74 in other areas. the captured species were rattus rattus (24), rattus norvegicus (69) and mus musculus domesticus (45). serological (catt/t. evansi), pa ...201020888126
