Abstract Recent fieldwork in Gran Canaria and Tenerife (Canary Islands, Spain), mostly between 2012 and 2016, yielded new chorological data for several non-native vascular plant species. The following are considered naturalized and/or potentially invasive: Callistemon viminalis, Casuarina glauca, Chloris barbata, Cyperus difformis, Eucalyptus gomphocephala, E. sideroxylon, Nephrolepis cordifolia, Rumex palustris, Senna × artemisioides (s.l.) and S. × floribunda and are reported for the first time from the Canary Islands. Other first records include: Cascabela thevetia (Tenerife), Cyclospermum leptophyllum (Gran Canaria), Digitaria radicosa (Gran Canaria, Tenerife), Dysphania anthelmintica (Tenerife), Erythrostemon gilliesii (Tenerife), Heliotropium supinum (Tenerife), Limoniastrum monopetalum (Tenerife), Nerium oleander (Tenerife), Pascalia glauca (Tenerife), Phytolacca americana (Tenerife), Podranea ricasoliana (Gran Canaria), Psidium guajava (Gran Canaria), Rumex cristatus (Tenerife), Schinus terebinthifolia (Tenerife), Solandra maxima (Tenerife), Tipuana tipu (Tenerife) and Youngia japonica (Gran Canaria). More than 20 additional taxa also represent chorological novelties but are considered ephemerals. Finally, miscellaneous notes are added for Diplachne fusca subsp. uninervia, Eclipta prostrata, Pluchea carolinensis, Prosopis juliflora and Sida rhombifolia from Gran Canaria.

The study of the militias in the Canary archipelago has been a recurring theme in insular historiography, addressed by different authors in breadth and depth, covering not only their organization but also the strategy and weapons used in moments of danger. However, the presence of the presidios in the Canary Islands has had fewer options, as they are professional troops, passing through and reinforcement, that operate on the islands at specific times. The objective, therefore, that we pursue in this study is. in the development of Gran Canaria defense, to oppose the two types of forces that operated in its territory and their characteristics and consequences.

<p><b>Abstract</b></p> <p>Introduction: This study raised the following problem: How reliable and relevant is the <i>Inclusion for Children and Adolescents Questionnaire </i>(ICAQ)<i> </i>to measure the attitudes of children and adolescents with cochlear implants (CIs) or hearing aids (HAs) to inclusive education (IE) in public schools in the Canary Islands (i.e. provinces of Gran Canaria and Tenerife)? </p> <p>Method: The sample consisted of 297 students from the province of Gran Canaria, and 137 students from the province of Tenerife with an average of 11 years old. An exploratory factor analysis (EFA) determined the reliability and relevance of ICAQ. </p> <p>Results: The authors found four factors of students’ attitudes towards IE: <i>Family involvement and use of technology, Inclusion in the centre, Communication with medical specialists </i>and<i> Assessment of the support technology</i>. </p> <p>Conclusions: There were significant differences between the students with CIs and HAs in the following factors: <i>Inclusion in the centre</i> and <i>Assessment of the support technology</i>. The total score of students’ attitudes towards IE was high. The factor <i>Inclusion in the centre</i> had the most favourable total score of students’ original attitudes towards IE. <i>Communication with medical specialists </i>was the lowest total attitude score towards IE for students with CIs.</p>

A monitoring programme was established to collect plankton samples and information of environmental variables over the shelf off the island of Gran Canaria during 2005 and 2006. It produced a detailed snapshot of the composition and seasonal assemblages of the decapod larvae community in this locality, in the subtropical waters of the Canary Islands (NE Atlantic), where information about crustacean phenology has been poorly studied. The larval community was mainly composed of benthic taxa, but the contribution of pelagic taxa was also significant. Infraorders Anomura (33.4%) and Caridea (32.8%) accounted for more than half the total collected larvae. High diversity, relatively low larval abundance throughout the year and weak seasonality characterized the annual cycle. However, in relation to the temporal dynamics of temperature, two distinct larval assemblages (cold and warm) were identified that correspond to periods of mixing and stratification of the water column. The results also indicate that larval release times and durations in the subtropical waters are earlier and longer than at other higher latitudes in the NE Atlantic. We detected the presence of larvae of six species that have not yet been reported from the Canary Islands (Pandalina brevirostris, Processa edulis, Necallianasa truncata, Parapenaeus longirostris, Crangon crangon, Nematopagurus longicornis). Finally, this study provides a baseline for future comparisons with respect to fishery pressure and climate variability in this subtropical region.

Alloclita canariensis Koster &amp; Junnilainen sp. nov. is described from the Canary Islands Fuerteventura, Gran Canaria, Lanzarote and Tenerife. Two specimens from Gran Canaria were previously misidentified as A. francoeuriae Walsingham, 1905, a North African species. We record A. francoeuriae also as new for the Canary Islands, from Fuerteventura. The potential hostplants of A. canariensis are Asteriscus species (Asteraceae). DNA barcodes of both species are provided and compared with five other Alloclita species. The related Alloclita subitariella (Riedl, 1993), only known from the holotype from Saudi Arabia, is redescribed. These three species are placed in the new Alloclita francoeuriae group.
