The Others of the Ravine

In the society and culture of the Canary Islands, ravines (barrancos in Spanish) are spaces that contain a wealth of meanings and perceptions attached to a collective imagination. These natural scars that mark and characterize the island's geography represent scenes of dissidence, as will be shown through the spatial and geographic stories of various transsexuals and transvestites who lived in Tenerife between 1970 and 1990; the specific character of their testimonials is situated in a specific context: El Cabo, a barrio in Tenerife, as well as the Santos Ravine (Barranco de Santos in Spanish). The state repression, marginalization, and violence against sexually dissident people during this age will be the main context of analysis. In a brief journey through history, these aspects will be placed in relation to key events from the Francoist dictatorship on the islands, a travel journal of the nineteenth century, and passages from the conquest of the Canary Islands in which the ravines, among them the Santos Ravine itself, take on a relevant importance. Finally, this study will mention the existence of a chapel consecrated to the Virgin of Candelaria in this environment as possibly the most significant crystallization of the otherness of the ravine. This study thereby contemplates reviewing these spaces on the basis of their formation as media in which specific Canary Island subjectivities can be located.

The Resident Subsidy Impact on Regional Air Carrier Route Development: A Case Study

Subsidizing air mobility for Canary Island residents may have an unforeseen impact on regional air carrier route development and this could exacerbate congestion in airports that operate near to their maximum threshold. Reginal routes often require the use of small aircraft such as those from the ATR (Avions de Transport Régional) family. These aircraft types have [some specific characteristics related to its time performance. If airports manage a large proportion of ATR aircrafts, one of their main activities, such as landing and taking off operations (LTO), may become congested, and affect airport capacity. Air carrier economies might be negatively affected because of delays in airport operations. For instance, air carriers’ fuel costs might rise due to aircraft’s increased LTO time. This paper seeks to analyze the impact of regional aviation route development for the Canary airport network; specifically, the effect that it has on airport capacity and air carrier economies.

Phylogeography of Hyalomma (Euhyalomma) lusitanicum (Acarina, Parasitiformes, Ixodidae) in Andalusia based on mitochondrial cytochrome oxidase I gene

The genetic population structure relationships of Hyalomma (Euhyalomma) lusitanicum in Andalusia (the south of the Iberian Peninsula) were examined using mtDNA sequence data from 887 bp of cytochrome oxidase subunit I (COI) gene. The sequence for the COI region was determined for 84 individuals collected in several localities of Andalusia, and 10 for other localities (i.e., five from Toledo, central Iberian Peninsula, four from Sicily (Italy) and one from Canary Island). Seventeen haplotypes were detected, including 27 polymorphic sites. The number of amino acid substitutions per site from mean diversity calculations for the entire population was 0.017. AMOVA analysis revealed a low gene flow that characterises the genetic population structure of this species in South Iberian Peninsula, with a haplotype diversity (h) value of 0.815. No geographically induced differentiation was observed, and separate evolutionary units were not detected. Our results indicate low genetic diversity across the geographical range of H. lusitanicum tick in Andalusia. Our data do not show any genetic discontinuity between the tick populations studied, including specimens from Canary Island and Sicily (Italy).

The Role of Canary Island Date Palms in Physical Amenity Provisioning for Urban Landscape Settings

Canary Island date palms (Phoenix canariensis) have been planted as a landscaping feature plant throughout warm, temperate, and subtropical climates. The physical amenity provisioning of this species (shade effects, microclimate amelioration, water usage, etc.) has so far not been systematically assessed. This paper reports on temperature and humidity measurements in both a suburban and a rural location in SE Australia. The study demonstrates the effects of the palm canopy as regulator of humidity and provider of shade and, thus, amenity values in urban landscape settings. Drawing on published energy savings and growth requirements of the plant, the paper argues that Canary Island date palms are landscaping plants suitable to ameliorate the microclimate in urban neighborhoods with varied socio-economic conditions.
