The concept of geodiversity is becoming more widely used every year, beyond its contribution to the development of geotourism. It is estimated that geodiversity is as important as biodiversity in the functioning of Earth’s natural ecosystems. Therefore, an important problem is to recognize the possibilities on integrating geodiversity in geographic education, both formal and informal. The main aim of the study is to identify the subject of educating godiversity, included in the core curricula in Spain and Canary Islands and to identify the forms, didactic tools and methods of geodiversity education existed in selected national, natural parks and geoparks of Canary Islands. The study has shown that the application of geodiversity in educational practice is still unsettled.

The paper presents the first record of a Chara connivens (Characeae) stand from Fuerteventura (Canary Islands, Spain). The species was previously recorded only on Tenerife and Lanzarote, mostly in marine and artificial habitats. Physicochemical parameters of water and morphological features of the thalli and plant community were analyzed. General habitat requirements of C. connivens populations located in Europe, North Africa, and South-West Asia were reviewed. The newly described stand was located in a natural rock crevice that was part of a riverbed in El Barranco de las Peñitas (Penitas Canyon). This habitat was unshaded and filled with brackish water. C. connivens co-occurred with Cladophora glomerata and Ruppia maritima. Our report on the presence of C. connivens in the Spanish territory of the Atlantic Ocean is the first in almost 40 years. The distribution of C. connivens and its plant associations on the Canary Archipelago are poorly explored, which is why this topic requires further research.

Tests for potentially pathogenic amoebae were carried out in order to determine the presence of free-living amoebae of genus Acanthamoeba in soil and beach sand sources related to human environments in Tenerife, Canary Islands, Spain. Acanthamoeba identification was based on the morphology of cyst and trophozoite forms and PCR amplification with a genus specific primer pair. The pathogenical potential of Acanthamoeba isolates was characterized by temperature and osmotolerance assays and PCR reactions with two primer pairs related to Acanthamoeba pathogenesis. The results demonstrate the presence of potential pathogenic strain in both sources. Thus, some of the amoebae found in these habitats could act as opportunistic pathogens and may present a risk to human health.

The Blue Chaffinch is a passerine endemic to the Canary Islands and comprises two subspecies, one found on Tenerife (Fringilla teydea teydea) and the other on Gran Canaria (F. t. polatzeki). Even though the status of the Gran Canaria subspecies is endangered due to habitat loss and fragmentation, knowledge of its life history is anecdotal. We studied its breeding ecology during the years 1991-2004. New data are presented on breeding phenology, number of broods per year, egg biometrics, nest-site characteristics, breeding site fidelity and breeding success. In general, the breeding biology of the two subspecies were similar, with discrepancies in some previously reported traits, such as egg laying interval and frequency of second clutches. The Blue Chaffinch breeds earlier on Gran Canaria than on Tenerife: nests were begun mainly in the second fortnight of May. We did not find any relationship between the onset of egg laying and rainfall in March. However, the onset of the breeding period was negatively correlated with mean April temperature. The Blue Chaffinch showed preferences for a south-easterly nest orientation and for nest placement at the end of branches, where the nest is hidden by pine needles. Nests were located at various heights, from 5.5 to 23.8 m above the ground. 33% of females produced two broods a year. We found no differences in nest site characteristics between successful and unsuccessful nests, which suggests that other factors may be affecting the vulnerability of nests. The main cause of nesting failure (73.9%) was predation, due mostly to the Great Spotted Woodpecker.

Zięba kanaryjska jest endemitem Wysp Kanaryjskich, tworzącym dwa podgatunki — na Teneryfie (Fringilla teydea teydea) i Gran Canaria (F. t. polatzeki). Biologię lęgową tego ostatniego badano w okresie od 1991 do 2004. Stwierdzono, że przystępuje on do lęgów wcześniej niż podgatuunek zasiedlający Teneryfę (głównie w drugiej połowie maja, Fig. 1, Fig. 2). Nie stwierdzono związku między czasem rozpoczęcia lęgów i opadami w marcu, natomiast początek sezonu lęgowego był negatywnie skorelowany ze średnią temperaturą kwietnia (Fig. 3). Około 33% samic odbywało dwa lęgi w sezonie, zaś główną przyczyną strat lęgów (niemal 74%) było drapieżnictwo, przede wszystkim ze strony dzięcioła dużego.

Termin „Guanczowie” posiada dwa znaczenia. W szerszym używany jest na określenie wszystkich ludów autochtonicznych Wysp Kanaryjskich. W węższym Guanczowie to tubylcy zamieszkujący w przeszłości Teneryfę. W artykule zaprezentowano informacje dotyczące autochtonicznego ludu Teneryfy. W 1496 roku ostatnia z Wysp Kanaryjskich, Teneryfa, została podbita przez Hiszpanów. Guanczowie zostali wymordowani lub sprzedani do niewoli. Ślady ich historii, kultury i wierzeń są tam do dzisiaj obecne. Pochodzenie piramid z Güímar nadal stanowi temat niewyjaśniony przez naukowców. Interesujące wydają się też badania prowadzone nad Kanaryjskim Kamieniem z Rosetty – Piedra Zanata. Ciekawie przedstawia się legenda dotycząca figurki Matki Bożej z Candelarii.

The term: Guanches has two meanings: In the wider sense, it refers to all aboriginal inhabitants of the Canary Islands; in the narrower sense, it refers only to the inhabitants of the Tenerife. This article treats of the autochthons of the Tenerife, the last Canary Island conquered by the Spaniards in 1496. Guanches were killed en masse, and the survivors sold into slavery. Some traces of their history, culture and beliefs are still discernible today, though shrouded in mystery, like the origins of the Pyramids of Güímar, or Piedra Zanata, considered the Rosetta Stone of the Canary, or the fascinating legend of the figure of Our Lady of Candelaria. The author of this article describes the social life of the Guanches, their religious beliefs and material culture.

In the Canary Islands, groundwater is the main source of drinking water. Groundwater mines have been the system used by the engineers of the archipelago to collect water from the ground. The Canary Islands are volcanic with soils characterized by being rich in uranium, the disintegration of which gives rise to radon gas. In this study, radon gas levels in the mines on two islands of the archipelago have been measured to study exposure to this gas in the galleries. Results show values much higher than the European regulatory limit concentrations.

Although the Ring Ouzel has been considered accidental in the Canary Islands, it has been observed for the last five years in the high mountain zone of Tenerife (Canary Islands), showing it to be a regular winter visitor. Its interaction with female Juniperus cedrus cones and seeds was studied by analysing its wintering diet during January-April 2008. This juniper is endemic to the Canaries and Madeira and is classified as endangered by the IUCN. Previously, its sole long-distance disperser was known to be the Raven Corvus corax, which is unfortunately now extinct in the distribution range of J. cedrus. The results show that the diet of T. torquatus in Tenerife consists mostly of female J. cedrus cones (95% of the biomass consumed). Due to the large amount of seeds dispersed by Ring Ouzels and the effectiveness in seed germination, this winter visitor constitutes an important vector in the dispersal of J. cedrus that appears to have gone undetected in the past. This passerine plays a key role in its seed dispersal system, being able to move seeds over long distances, thus connecting fragmented populations of this plant. The present work is one of the few cases described in which a plant endemic to an oceanic island is so dependent on a winter visitor, and highlights the importance of insular environments in the wintering range of the Ring Ouzel. Owing to the absence of native long-distance seed dispersers, the future fate of this conifer is now probably dependent on the wintering population of this thrush.

Jałowiec kanaryjski jest gatunkiem endemicznym występującym na Teneryfie i Maderze. Istotną rolę w dalekodystansowym przenoszeniu nasion tego gatunku pełnił do tej pory kruk, który obecnie jednak zanikł na obszarze występowania tego jałowca. Drozd obrożny dość rzadko zimuje na Wyspach Kanaryjskich, ale w ostatnich latach (2004—2008) był obserwowany regularnie w strefie wysokogórskiej na Teneryfie. Rolę tego gatunku w rozsiewaniu nasion jałowca określano badając skład pokarmu zimowego (między styczniem a kwietniem) na podstawie analiz kału. Prace prowadzono w dwóch lokalizacjach w Parku Narodowym „El Teide” zimą i wiosną 2008 r. Kał żerujących ptaków zbierano głównie z ziemi wokół krzaków jałowca, oraz w miejscach używanych przez ptaki jako wodopoje. Stwierdzono, że w 93% pokarm drozdów składał się z owoców jałowca, a w 2.5% z owoców szakłaka Rhamnus integrifolia (Tab. 1). Bezkręgowce (gł. wije i chrząszcze) stanowiły 5% diety (Tab. 1). Po 230 nasion jałowca znalezionych w kale i zebranych wprost z owoców jałowca wysiano, aby ocenić ich zdolność kiełkowania. Nasiona po przejściu przez przewód pokarmowy drozda nie były uszkodzone, te znalezione w kale miały większą zdolność do kiełkowania (34%) niż kontrolne (17%). Drozd obrożny pełni więc ważną rolę w przenoszeniu nasion jałowca kanaryjskiego na dalsze odległości. Z drugiej strony tak silna zależność od jednego rodzaju pokarmu może prowadzić do zmniejszania liczebności zimujących drozdów w przyszłości w związku z zanikaniem zarośli jałowcowych. Uzyskane wyniki przedstawiają jeden z niewielu przykładów, gdy endemiczna roślina występująca na wyspie jest silnie zależna od zimującej populacji przelotnego gatunku ptaka.

The diet of the wild rabbit Oryctolagus cuniculus (Linnaeus, 1758) on Alegranza Island (Canary Islands) was studied by microhistological examination of faecal samples. We compared the presence of each food-plant species in the faeces across a year in comparison with plant availability. Two areas were studied, Llano de la Vega and La Caldera. At the first site, Suaeda vera and Chenoleoides tomentosa were the most common plants, while at the latter it was Euphorbia regis-jubae. In general, species belonging to the Chenopodiaceae were most commonly eaten by rabbits. Plants such as Chenoleoides tomentosa and Salsola vermiculata were most important in the diet in every season. Levin's niche-breadth was broader across the seasons in the study site of La Caldera than at Llano de la Vega. Furthermore, this parameter yielded the highest values (broadest niche) during the spring at both sites. Most important plants eaten by rabbits showed green vegetative parts through all seasons. Rabbits selected some plants independently of their availability, even in this reduced insular environment. The feeding behaviour of rabbits in Alegranza, selecting certain species, must have had important consequences on the composition and distribution of the vegetation over the years. This negative effect on island vegetation has been shown to occur on many oceanic islands of the world where rabbits have been introduced.

A total of 51 and 21 adults of Barbary ground squirrels (Atlantoxerus getulus) were trapped during May–July 2006 from the introduced populations on Fuerteventura Island (Canary Islands) and the native populations in Morocco, respectively. One trematode, 1 cestode and 4 nematode species were recovered belonging to five families: Brachylaima sp. (Brachylaimidae), Catenotaenia chabaudi (Catenotaeniidae), Protospirura muricola (Spiruridae), Dermatoxys getula and Syphacia pallaryi (Oxyuuridae), and Trichostrongylus sp. (Trichostrongylidae). We report for the first time the presence of P. muricola, Trichostrongylus sp. and Brachylaima sp. in A. getulus. Brachylaima sp. was found in the insular population only, as a result of a diet that includes snails. The two oxyurids were found at both sites. The continental population showed higher species richness (5 vs 3 species). This is the first report of helminth parasites from A. getulus from the Canary Islands.

Following a series of surveys with bottom longlines and fish traps along the island slopes off the archipelagos of Madeira, Canaries and Cape Verde, and with bottom trawls along the coast of Morocco and Western Sahara between 2004 and 2006 many specimens of Synaphobranchus were caught, revealing the presence of two species. Based on these specimens and Museum preserved specimens from this area grey cutthroat, Synaphobranchus affinis Gunther, 1877, is recorded for the first time from off Portugal, Madeira archipelago, Great Meteor Seamount, Canary Islands, Morocco, Western Sahara, Cape Verde Islands, and Senegal. It is confirmed that S. kaupii is also conspecific in this area. Meristic and morphometric data of the specimens studied are also presented.

Eleven parasite taxa were found infecting 68 Atlantic chub mackerel, Scomber colias Gmelin, 1789 from the Canary Islands, Central North Atlantic. The most abundant parasites were the gill monogenean Pseudokuhnia minor (P = 54.4%), larval anisakid nematodes (P = 11.8%) in the body cavity, a larval tetraphyllidean infecting bile ducts (P = 8.8%) and didymozoid digeneans infecting the gills (P = 7.4%). No correlation between fish length and abundance of infection with these parasites was found. Within the Atlantic, the comparison of present results with previous reports on the occurrence of parasites in this fish host, might suggest that there is more than one population unit of Atlantic chub mackerel in the Eastern Atlantic.
