AbstractThis 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 trapped Muridae hosts found to be parasitized by S. tripectinata came from humid biotopes. The results showed that S. tripectinata is present on all the western Canary Islands and on one of the eastern islands, Gran Canaria, the only island already reported. The detection of S. tripectinata on El Hierro, La Palma, La Gomera and Tenerife represents the first records of this flea species on those Canary Islands.

Pseudoniphargus was known from inland stygohabitats in the Iberian peninsula, the Azores, Madeira, N.W. Africa, and Bermuda, but not from the Canary Islands. Systematic sampling in six of the seven larger islands of the latter archipelago has revealed the presence of the genus in Tenerife (4 species), La Palma (2 species), La Gomera (1 species), and El Hierro (1 species). No Pseudoniphargus has been found in Lanzarote and Fuerteventura; Gran Canaria has not been sampled systematically.

AbstractThe 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 archipelago. Concerning to parasitofaunas stands out: a) impoverishment of biodiversity of helminths respect of which have the same hosts in other islands; b) increasing the number of species of Siphonaptera, even compared with flea species that parasitize the same hosts from continental biotopes.

En la actualidad, en las Islas Canarias se encuentran declarados 83 Bienes de Interés Cultural (BIC) con categoría de Zona Arqueológica (ZA). De ellos, 36 se encuentran en la isla de Gran Canaria, seguida por Tenerife con 27, Fuerteventura y La Palma con 5 zonas, el Hierro con 3, la Gomera con 2 y finalmente, Lanzarote con sólo una zona arqueológica. En este trabajo se reflejan algunas de las deficiencias en la gestión de este tipo de bienes, ocasionadas por el propio procedimiento de declaración, y que impiden una clara y fluida gestión del patrimonio arqueológico cuyo objetivo debería ser, a tenor de las más actuales tendencias en la gestión patrimonial, integrar, cohesionar y desarrollar social y económicamente los territorios. Para ello, se ha centrado el estudio en el análisis de la organización legal y administrativa en la gestión del patrimonio arqueológico, la política de autorizaciones de las intervenciones arqueológicas, la de protección reflejada en los BIC, la delimitación de áreas de protección y su conversión en parque arqueológico, lo que nos han ayudado a profundizar y mostrar el estado actual de los bienes arqueológicos canarios y avanzar en la evaluación y diagnóstico de la gestión del patrimonio arqueológico.

The scarcity of resources, the limited land, and the overstressing of tourism, as well as the estrangements of movement, make the insular territories relevant case studies in terms of their regional management and governance and, consequently, sustainable development. Thereby, Transportation and Infrastructures’ Sustainability in these territories is not an exception. In this regard, the present study, through exploratory tools, expects to analyze, using accessibility and connectivity indicators, the impacts over the social-economic sphere that the local Transportation and Infrastructures may deliver to the populations of the Canary Islands Archipelago. The study enables us to identify the islands of La Palma, El Hierro, Fuerteventura, and La Gomera as those with better accessibility patterns.

AbstractThe banana weevil (BW), Cosmopolites sordidus (Coleoptera: Curculionidae), is one of the most important insect pests of bananas and plantains. The mobility and the origin of BW infestations at the Canary Islands (Tenerife, La Gomera and La Palma) have been analysed using Random Amplified Polymorphic DNA (RAPD) as molecular markers. Populations from Costa Rica, Colombia, Uganda and Madeira were also included for comparison. One hundred and fifteen reproducible bands from eight primers were obtained. The level of polymorphism in the populations from the Canary Islands (40–62%) was in the range of those found in other populations. Nei's genetic distances, pair-wise fixation index (FST) values indicate that the closest populations are Tenerife populations among themselves (Nei's genetic distance=0.054–0.100; FST=0.091–0.157) and Costa Rica and Colombia populations (Nei's genetic distance=0.049; FST=0.113). Our results indicate the existence of BW local biotypes with limited gene flow and affected by genetic drift. These results are compatible with a unique event of colonization at Tenerife; whereas, the outbreaks in La Gomera and La Palma may come from independent introductions. The Madeira population is phylogenetically and geographically closer to the Canary Islands populations, suggesting that it is the most likely source of the insects introduced in the Canary Islands.

SUMMARYNon-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 flea co-occurrence on Rattus rattus and Mus musculus. Results supported aggregation of flea species in Mus but not in Rattus, probably due to the relationship between abundance and both prevalence and intensity of infection of the main flea species parasitizing Mus. In addition, heavy individuals of both rodent species showed the highest flea burdens as well as higher species richness, probably due to the continued accumulation of fleas throughout life and/or immunological resistance mechanisms. Whatever the mechanisms involved, it is clear that co-occurrence and high parasite intensities do not imply a detrimental biological cost for the rodents of the Canary Islands.
