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. -
Rainfall and Flooding in Coastal Tourist Areas of the Canary Islands (Spain)

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. -
Phylogeography of Finches and Sparrows
In: Animal Genetics ISBN: 978-1-60741-844-3 Editor: Leopold J. Rechi © 2009 Nova Science Publishers, Inc. Chapter 1 PHYLOGEOGRAPHY OF FINCHES AND SPARROWS Antonio Arnaiz-Villena*, Pablo Gomez-Prieto and Valentin Ruiz-del-Valle Department of Immunology, University Complutense, The Madrid Regional Blood Center, Madrid, Spain. ABSTRACT Fringillidae finches form a subfamily of songbirds (Passeriformes), which are presently distributed around the world. This subfamily includes canaries, goldfinches, greenfinches, rosefinches, and grosbeaks, among others. Molecular phylogenies obtained with mitochondrial DNA sequences show that these groups of finches are put together, but with some polytomies that have apparently evolved or radiated in parallel. The time of appearance on Earth of all studied groups is suggested to start after Middle Miocene Epoch, around 10 million years ago. Greenfinches (genus Carduelis) may have originated at Eurasian desert margins coming from Rhodopechys obsoleta (dessert finch) or an extinct pale plumage ancestor; it later acquired green plumage suitable for the greenfinch ecological niche, i.e.: woods. Multicolored Eurasian goldfinch (Carduelis carduelis) has a genetic extant ancestor, the green-feathered Carduelis citrinella (citril finch); this was thought to be a canary on phonotypical bases, but it is now included within goldfinches by our molecular genetics phylograms. Speciation events between citril finch and Eurasian goldfinch are related with the Mediterranean Messinian salinity crisis (5 million years ago). Linurgus olivaceus (oriole finch) is presently thriving in Equatorial Africa and was included in a separate genus (Linurgus) by itself on phenotypical bases. Our phylograms demonstrate that it is and old canary. Proposed genus Acanthis does not exist. Twite and linnet form a separate radiation from redpolls. -

We studied its inter-habi- tat diet variation on the largest of the Canaries, Tenerife, during the 2014–2015 breeding seasons. We also compared the current food spectrum (2014–2015) with that reported in a study conducted 30 years ago. Prey remains analyses were conducted at the three main forested habitats, two native (laurel forest and Canarian pinewood) and one exotic (exotic tree plantations). Birds formed the main dietary component of the Sparrowhawk (26 spe- cies identified), but mammals and reptiles were also consumed in small numbers. Avian prey of around 200–300 g were preferred by Sparrowhawks. Three species accounted for 63.4% of the total number of prey counted (Atlantic Canary Serinus canarius,RockPi- geon Columba livia and Blackbird Turdus merula), but their importance varied among habitats. -

We studied the niche characteristics of birds in managed small-sized green spaces in the urban core areas of southern (Kavala, Greece) and northern Europe (Rovaniemi, Finland), during the breeding season, based on a set of 16 environmental variables and using Outlying Mean Index, a multivariate ordination technique. Overall, 26 bird species in Kavala and 15 in Rovaniemi were recorded in more than 5% of the green spaces and were used in detailed analyses. In both areas, bird species occupied different niches of varying marginality and breadth, indicating varying responses to urban environmental conditions. Birds showed high specialization in niche position, with 12 species in Kavala (46.2%) and six species in Rovaniemi (40.0%) having marginal niches. Niche breadth was narrower in Rovaniemi than in Kavala. Species in both communities were more strongly associated either with large green spaces located further away from the city center and having a high vegetation cover (urban adapters; e.g., Common Chaffinch (Fringilla coelebs), European Greenfinch (Chloris Citation: Liordos, V.; Jokimäki, J.; chloris Cyanistes caeruleus Kaisanlahti-Jokimäki, M.-L.; ), Eurasian Blue Tit ( )) or with green spaces located closer to the city center Valsamidis, E.; Kontsiotis, V.J. -

AERC Wplist July 2015
AERC Western Palearctic list, July 2015 About the list: 1) The limits of the Western Palearctic region follow for convenience the limits defined in the “Birds of the Western Palearctic” (BWP) series (Oxford University Press). 2) The AERC WP list follows the systematics of Voous (1973; 1977a; 1977b) modified by the changes listed in the AERC TAC systematic recommendations published online on the AERC web site. For species not in Voous (a few introduced or accidental species) the default systematics is the IOC world bird list. 3) Only species either admitted into an "official" national list (for countries with a national avifaunistic commission or national rarities committee) or whose occurrence in the WP has been published in detail (description or photo and circumstances allowing review of the evidence, usually in a journal) have been admitted on the list. Category D species have not been admitted. 4) The information in the "remarks" column is by no mean exhaustive. It is aimed at providing some supporting information for the species whose status on the WP list is less well known than average. This is obviously a subjective criterion.

Advances in the Study of Irruptive Migration
Advances in the study of irruptive migration Ian Newton1 Newton I. 2006. Advances in the study of irruptive migration. Ardea 94(3): 433–460. This paper discusses the movement patterns of two groups of birds which are generally regarded as irruptive migrants, namely (a) boreal finches and others that depend on fluctuating tree-fruit crops, and (b) owls and others that depend on cyclically fluctuating rodent popula- tions. Both groups specialise on food supplies which, in particular regions, fluctuate more than 100-fold from year to year. However, seed- crops in widely separated regions may fluctuate independently of one another, as may rodent populations, so that poor food supplies in one region may coincide with good supplies in another. If individuals are to have access to rich food supplies every year, they must often move hun- dreds or thousands of kilometres from one breeding area to another. In years of widespread food shortage (or high numbers relative to food supplies) extending over many thousands or millions of square kilome- tres, large numbers of individuals migrate to lower latitudes, as an ‘irruptive migration’. For these reasons, the distribution of the popula- tion, in both summer and winter, varies greatly from year to year. In irruptive migrants, in contrast to regular migrants, site fidelity is poor, and few individuals return to the same breeding areas in succes- sive years (apart from owls in the increase phase of the cycle). Moreover, ring recoveries and radio-tracking confirm that the same indi- viduals can breed in different years in areas separated by hundreds or thousands of kilometres.
