H3.3 Macaronesian Inland Cliff
European Red List of Habitats - Screes Habitat Group H3.3 Macaronesian inland cliff Summary The perennial vegetation of crevices and ledges of cliff faces in Macaronesia away from coastal salt-spray is of very diverse character - some, for example, dominated by succulents, others rich in ferns and bryophytes characteristic of shaded situations - and it includes several hundreds of taxa endemic to the archipelagoes. The main threats are mountaineering and rock climbing, outdoor sports and leisure activities, and construction of infrastructures such as roads and motorways. Synthesis There is no evidence of significant past reductions, either in the last 50 years or historically, and also future prospects are good, as no serious threats are envisaged, besides touristic/leisure activities and putative faulty environmental impact assessments that may overlook this habitat as valuable. Reduction in quantity, reduction in quality and criteria of geographic distribution yield the Least Concern (LC) category. In spite of the LC category, conservation policy and management should restrict to the maximum any threat to or reduction of the habitat, as it has a very high conservation value, because of high endemism of species and communities with many local and regional variaties. Overall Category & Criteria EU 28 EU 28+ Red List Category Red List Criteria Red List Category Red List Criteria Least Concern - Least Concern - Sub-habitat types that may require further examination Four general subtypes can be distinguished based on species composition and different ecological conditions. However, at present, no data are available to carry out an individual assessment of each of them. In the future, if detailed plot sampling has been carried out, such an evaluation may be possible. -
Gradient Analysis of Exotic Species in Pinus Radiata Stands of Tenerife (Canary Islands) S
The Open Forest Science Journal, 2009, 2, 63-69 63 Open Access Gradient Analysis of Exotic Species in Pinus radiata Stands of Tenerife (Canary Islands) S. Fernández-Lugo and J.R. Arévalo* Departamento de Ecología, Facultad de Biología, Universidad de La Laguna, La Laguna 38206, Spain Abstract: Identifying the factors that influence the spread of exotic species is essential for evaluating the present and future extent of plant invasions and for the development of eradication programs. We randomly established a network of 250 plots on an exotic Pinus radiata D. Don plantation on Tenerife Island in order to determine if roads and urban centers are favouring the spread of exotic plant species into the forest. We identified four distinct vegetation groups in the P. radiata stands: advanced laurel forest (ALF), undeveloped laurel forest (ULF), ruderal (RU), and Canarian pine stand (CPS). The groups farthest from roads and urban nuclei (ALF and CPS) have the best conserved vegetation, characterizing by the main species of the potential vegetation of the area and almost no exotic and ruderal species. On the other hand, the groups nearest to human infrastructures (ULF and RU) are characterized by species from potential vegetation’s substitution stages and a higher proportion of exotic and ruderal species. The results indicate distance to roads and urban areas are disturbance factors favouring the presence of exotic and ruderal species into the P. radiata plantation. We propose the eradication of some dangerous exotic species, monitoring of the study area in order to detect any intrusion of alien species in the best conserved areas and implementation of management activities to reduce the perturbation of the ULF and RU areas. -

Phylogeny of Southern African and Australasian Wahlenbergioids (Campanulaceae) based on ITS and trnL-F sequence data: implications for a reclassification Christopher N. Cupido , Jessica M. Prebble , and William M. M. Eddie Abstract The Campanulaceae: Wahlenbergioideae currently comprises 15 genera, one of which, Wahlenbergia, is widespread over the southern continents. Southern Africa is the region with maximum wahlenbergioid diversity with 12 genera and approximately 252 species. A second center is Australasia with 38 Wahlenbergia species. This study used a broad sample of wahlenbergioid diversity from South Africa, Australia, and New Zealand to reconstruct a phylogeny based on chloroplast trnL-F and nuclear ITS sequences. Data were analyzed separately and in combination using parsimony and Bayesian methods. The results suggest that for the wahlenbergioids to be monophyletic Wahlenbergia hederacea has to be excluded and that none of the South African, Australian or New Zealand lineages are strictly monophyletic. There are five species assemblages that are in some disagreement with current classification in the family. Wahlenbergia, Prismatocarpus and Roella are shown to be non-monophyletic and implications for a reclassification are presented. Careful consideration of morphological characters is suggested before the adjustment of generic circumscriptions can be accomplished. Recent family-wide molecular phylogenetic studies have supported the view that the Campanulaceae s.s. -
Checklists of Crustacea Decapoda from the Canary and Cape Verde Islands, with an Assessment of Macaronesian and Cape Verde Biogeographic Marine Ecoregions

GONZÁLEZ University of Las Palmas de Gran Canaria, i-UNAT, Campus de Tafira, 35017 Las Palmas de Gran Canaria, Spain. E-mail: [email protected]. ORCID iD: 0000-0001-8584-6731. Abstract The complete list of Canarian marine decapods (last update by González & Quiles 2003, popular book) currently com- prises 374 species/subspecies, grouped in 198 genera and 82 families; whereas the Cape Verdean marine decapods (now fully listed for the first time) are represented by 343 species/subspecies with 201 genera and 80 families. Due to changing environmental conditions, in the last decades many subtropical/tropical taxa have reached the coasts of the Canary Islands. Comparing the carcinofaunal composition and their biogeographic components between the Canary and Cape Verde ar- chipelagos would aid in: validating the appropriateness in separating both archipelagos into different ecoregions (Spalding et al. 2007), and understanding faunal movements between areas of benthic habitat. The consistency of both ecoregions is here compared and validated by assembling their decapod crustacean checklists, analysing their taxa composition, gath- ering their bathymetric data, and comparing their biogeographic patterns. Four main evidences (i.e. different taxa; diver- gent taxa composition; different composition of biogeographic patterns; different endemicity rates) support that separation, especially in coastal benthic decapods; and these parametres combined would be used as a valuable tool at comparing biotas from oceanic archipelagos. -

As the origin of flood events is usually associated with intense precipitation episodes, this study considers the general rainfall characteristics of tourist resorts in two islands of the Canary Archipelago (Spain). Days of intense rainfall were determined using the 99th percentile (99p) of 8 daily precipitation data series. In addition, the weather types that generated these episodes were identified, the best-fitting distribution functions were determined to allow calculation of probable maximum daily precipitation for different return periods, and the territorial and economic consequences of flood events were analysed. The results show highly irregular rainfall, with 99p values ranging 50–80 mm. The weather types associated with 49 days of flooding events were predominantly cyclonic and hybrid cyclonic. The Log Pearson III distribution function best fitted the data series, with a strong likelihood in a 100-year return period of rainfall exceeding 100 mm in a 24 h period. -

(Strawberry tree) belongs to Ericaceae family, is an evergreen shrub or tree, mostly known around Mediterranean region in natural habitat, has valuable medicinal and aromatic properties. The plant is mainly used for its edible fruits. In addition, A. unedo have increasing importance in afforestration programmes, beekeeping facilities, ornamental purposes and elucidating plant physiology. Therefore, the species is seemingly a promising fruit plant. Orchards are very limited but increasing demand to the plant will result in initiations of establishment new fruit orchards with superior genotypes viz. tolerant to the abiotic stress, resistant to pests and diseases, rich contents in terms of valuable compounds, convenience to postharvest operations, being visually preferable and suitable to target climate. Plant breeding is an important component to overcome elimination of unwanted features and to reach admirable characters. The main steps in breeding are effective selection, succesfully adaptation and inheritance via transferring the features to subsequent generations. -
Checklist of the Vascular Alien Flora of Catalonia (Northeastern Iberian Peninsula, Spain) Pere Aymerich1 & Llorenç Sáez2,3
BOTANICAL CHECKLISTS Mediterranean Botany ISSNe 2603-9109 https://dx.doi.org/10.5209/mbot.63608 Checklist of the vascular alien flora of Catalonia (northeastern Iberian Peninsula, Spain) Pere Aymerich1 & Llorenç Sáez2,3 Received: 7 March 2019 / Accepted: 28 June 2019 / Published online: 7 November 2019 Abstract. This is an inventory of the vascular alien flora of Catalonia (northeastern Iberian Peninsula, Spain) updated to 2018, representing 1068 alien taxa in total. 554 (52.0%) out of them are casual and 514 (48.0%) are established. 87 taxa (8.1% of the total number and 16.8 % of those established) show an invasive behaviour. The geographic zone with more alien plants is the most anthropogenic maritime area. However, the differences among regions decrease when the degree of naturalization of taxa increases and the number of invaders is very similar in all sectors. Only 26.2% of the taxa are more or less abundant, while the rest are rare or they have vanished. The alien flora is represented by 115 families, 87 out of them include naturalised species. The most diverse genera are Opuntia (20 taxa), Amaranthus (18 taxa) and Solanum (15 taxa). Most of the alien plants have been introduced since the beginning of the twentieth century (70.7%), with a strong increase since 1970 (50.3% of the total number). Almost two thirds of alien taxa have their origin in Euro-Mediterranean area and America, while 24.6% come from other geographical areas. The taxa originated in cultivation represent 9.5%, whereas spontaneous hybrids only 1.2%. From the temporal point of view, the rate of Euro-Mediterranean taxa shows a progressive reduction parallel to an increase of those of other origins, which have reached 73.2% of introductions during the last 50 years. -
Effect of Fire Intensity on Non-Native Plant Species Community in a Canarian Pine Forest Three and Eleven Years After Fire C
70 The Open Forest Science Journal, 2009, 2, 70-77 Open Access Effect of Fire Intensity on Non-Native Plant Species Community in a Canarian Pine Forest Three and Eleven Years After Fire C. García-Domínguez* and J.M. Fernández-Palacios Departamento de Ecología, Facultad de Biología, Universidad de La Laguna, La Laguna 38206, España Abstract: The invasion of non-native plant species is one of the greatest threats to natural ecosystems, and oceanic islands are especially susceptible to this threat. Fire, as a disturbance factor, has been found to promote non-native species invasion and fire intensity is one of the variables determining the severity of invasions. This study was designed to determine the impact of non-native species in the Tenerife pine forest understory on the island of Tenerife, Canary Islands, Spain, and how they are affected by low and high intensity wildfire. We resampled in 2006 the plots set for a previous study in 1998 within the area affected by a wildfire in June 1995. Six control plots, nine low-severity burned plots and twelve high-severity burned plots were sampled three and eleven years after fire. Native species cover increased in high severely burned plots with respect to control plots. It also increased in low and high severely burned plots from 1998 to 2006. No differences were found for non-native cover and richness between fire intensities or in time. Results suggest that some of the native understory plant species are adapted to high intensity fire and respond by increasing their cover after fire to the detriment of non-native species. -

In this regard, the purpose of the present study was to investigate posthatching growth of body weight and seven morphometric parameters in Barbary partridges Alectoris barbara originated from low- and high elevations, and raised in common captive environment. Gompertz model presents the best fit to the growth curves for body weight, wing, leg and sternum. Mean body weight at hatching was similar between elevations and was relatively higher, compared to that in other studied perdicine species. Adult Barbary partridges from high and low elevations maintained the difference in body weight when raised in common captive envi- ronment. This suggests a role of genetic selection and / or maternal effects between the two studied populations. However, all the other growth parameters of morphological traits were similar between captive birds originated from the two elevations. This lack of difference could be related to a potential phenotypic plasticity with a convergence in common captive environment.
