The faunas of volcanic islands must necessarily be introduced, and more recent introductions can be recognized by the patterns of their distributions. This is obvious in the Canary Islands, where we have spent 30 days studying distributions of Spirorbidae. We now regard these as a distinct family following Pillai (1970). We sampled all the major islands, by shore collecting and diving to about 10 m, and on almost all we found nine Mediterranean species, namely Protolaeospira striata (Quiévreux, 1963) and the eight opercular incubators (species of Pileolaria and Janua) that have been recorded from both Marseilles (Zibrowius, 1968) and Chios (Bailey, 1969).

Fossil Data

ABSTRACT Bats are one of the most abundant and important mammals in ecosystems. However, their fossil record is scarce and fragile, making them difficult to find. Accordingly, there is no record of this group in the volcanic islands of the mid-Atlantic Ocean apart from the Canary Islands. This paper studies the first bat fossil record of the Canary Islands (Spain). The material studied is found within two Quaternary lava tubes, Cueva de los Verdes on Lanzarote and Cueva Roja on the island of El Hierro. The dental and humeral morphology and biometry are analysed and compared with current specimens. Among our results we highlight the first fossil data of two species endemic to the islands of the mid-Atlantic Ocean, Plecotus teneriffae and Pipistrellus maderensis, the former from the Canary Islands and the latter from the Azores, Madeira and the Canary Islands. We also confirm the presence of Pipistrellus kuhlii in the fossil record of the island of Lanzarote. No differences are observed between the dental morphology of the current and the fossil populations of P. maderensis and Pl. teneriffae. In the case of P. kuhlii, the populations of the Canary Islands and the Iberian Peninsula show differences in the paraconule with respect to the populations from central Europe. Palaeoecological studies of these taxa suggest that these islands presented a similar habitat when the sites were formed to the present-day habitat.

Grief is a natural and self-limited process of adaptation to a new reality that arises after a significant loss, real or perceived, with a wide range of manifestations that produce an impact on the health of the mourner. Objective: To know and identify, broken down by diagnostic gradient, the prevalence of mourning in the Canary Islands, as well as the needs of care before the diagnosis of mourning of the mourners. Results: Significantly, more women than men are identified in the three diagnostic labels under study. Patients with bereavement complications previously presented depression, anxiety, and risk of loneliness. The result of the pattern assessment is paradoxical. Conclusion: Grief is a multidimensional phenomenon that can hardly be assessed from a reductionist tool such as functional patterns. The high prevalence of complications in women’s grief should be studied in-depth, associating it with their previous burdens of care and vulnerability. The association between loneliness and complicated grief is evident, and the role of community nurses in these patients may be essential. Further research is needed on the care needs of bereaved persons, both complicated and uncomplicated, as well as on their predictive and protective factors.

Volcanic islands are often affected by ground displacement such as slope instability, due to their peculiar morphology. This is the case of Ischia Island (Naples, Italy) dominated by the Mt. Epomeo (787 m a.s.l.), a volcano-tectonic horst located in the central portion of the island. This study aims to follow a long temporal evolution of ground deformations on the island through the interferometric analysis of satellite SAR data. Different datasets, acquired during Envisat, COSMO-SkyMed and Sentinel-1 satellite missions, are for the first time processed in order to obtain the island ground deformations during a time interval spanning 17 years, from November 2002 to December 2019. In detail, the multitemporal differential interferometry technique, named small baseline subset, is applied to produce the ground displacement maps and the associated displacement time series. The results, validated through the analysis and the comparison with a set of GPS measurements, show that the northwestern side of Mt. Epomeo is the sector of the island characterized by the highest subsidence movements (maximum vertical displacement of 218 mm) with velocities ranging from 10 to 20 mm/yr. Finally, the displacement time series allow us to correlate the measured ground deformations with the seismic swarm started with the Mw 3.9 earthquake that occurred on 21 August 2017. Such correlations highlight an acceleration of the ground, following the mainshock, characterized by a subsidence displacement rate of 0.12 mm/day that returned to pre-earthquake levels (0.03 mm/day) after 6 months from the event.

En este artículo analizamos el tratamiento didáctico que recibe el patrimonio arqueológico canario de la etapa indígena en los libros de texto de Ciencias Sociales de Primaria de Canarias, con un especial foco de atención en la representación de género. A partir de un análisis cualitativo y cuantitativo, centrado en los libros de texto de cuatro editoriales, en el marco de la LOMCE, nuestra investigación analiza qué se considera patrimonio arqueológico en la enseñanza, cómo y qué se enseña, y cuál es el rol de las mujeres en el contenido educativo y en el hecho histórico. Los resultados obtenidos reflejan la reproducción de miradas eurocéntricas, la inexistencia de una definición explícita de los vestigios arqueológicos y, por tanto, del propio concepto de patrimonio, así como el predominio de la hegemonía cultural androcéntrica. Esta realidad presenta claras afinidades con la constatada en otros estudios afines del estado español. In this article we analyze the didactic approach for the Canarian archaeological heritage from the indigenous period within the Primary textbooks of Social Sciences in the Canary Islands, paying also attention to the representation of gender. From a qualitative and quantitative approach, focused on the textbooks from four different publishers, and within the framework of LOMCE, our research analyzes what is considered archaeological heritage in teaching, how and what is taught, and what is the role of women in the historic fact and in the educational content. The main results show the predominance of the androcentric cultural hegemony, the reproduction of Eurocentric views, the absence of an explicit definition for the archaeological remains and, therefore, for the concept of heritage. This panorama presents clear affinities with the one documented in other parts of Spain.
