Population genetic structure of North Atlantic killer whale samples was resolved from differences in allele frequencies 17 microsatellite loci, mtDNA control region haplotype and for a subset samples, using complete mitogenome sequences. Three significantly differentiated populations were identified. Differentiation based on greater between the two allopatric than pairs partially sympatric populations. Spatial clustering individuals within each these overlaps with distribution particular...
Stomach contents were analysed from 23 cetaceans, including individuals of 12 species the families Delphinidae, Physeteridae, Kogiidae and Ziphiidae, stranded between 1996 2006 in Canary Islands. Cephalopod mandibles ( beaks ) found 21 stomachs fish remains otoliths jaw bones appeared 4 stomachs. Two contained only eye lenses. Cephalopods eaten by dolphins mainly Ommastrephidae, Sepiidae Enoploteuthidae, whereas whales had taken specimens oceanic squid Histiotheutidae Cranchiidae. Fish...
Soil water infiltration is an important process whose behavior depends on external factors and soil properties, which vary depending the type of soil. The present paper aims to establish parameters determine steady‐state rate six Orders, all formed volcanic materials—Andisols (nonallophanic, allophanic, vitric), Inceptisols (typic, andic, vertic), Alfisols, Vertisols, Aridisols, Entisols (psamments, fluvents), contribute differences between them. study was conducted at 108 sites island...
Abstract Depending on the severity of fire, forest fires may modify infiltration and soil erosion processes. Rainfall simulations were used to determine hydrological effects fire Andisols in a pine burned by wildfire 2007. Six zones with different severities compared unburned zones. Infiltration, runoff loss analysed slopes 10% 30%. Forest floor properties evaluated. Unburned exhibited relatively low (23 16 mm h −1 30% slope angles, respectively) high average runoff/rainfall ratios (43% 50%...
Aggressive encounters involving cetacean species are widely described in the literature. However, detailed pathological studies regarding lesions produced by these scarce. From January 2000 to December 2017, 540 cetaceans stranded and were necropsied Canary Islands, Spain. Of them, 24 cases of eight presented social traumatic same or different species. All severe multifocal vascular changes, 50% (12/24) fractures affecting mainly thoracic region, 41.7% (10/24) acute rake marks, 37.5% (9/24)...
Summary Soil temperature influences both soil formation processes and land use possibilities, is a classification criterion in some systems. Vegetation cover one of the factors that affects temperature. In this paper, we estimate classes regimes, using Taxonomy, for Andosols located parts island Tenerife, Canary Islands, Spain, which are influenced by trade winds. The study focuses on soils under three types natural vegetation – cloud forest, tree‐heath woodland pine forest adjacent plots...
Abstract In oceanic ecosystems, the nature of barriers to gene flow and processes by which populations may become isolated are different from terrestrial environment, less well understood. this study we investigate a highly mobile species (the sperm whale, Physeter macrocephalus ) that is genetically differentiated between an open North Atlantic population in Mediterranean Sea. We apply high‐resolution single nucleotide polymorphism (SNP) analysis system, assessing putative boundary into...
The behavioural context provides opportunities for studying the use and characteristics of acoustic signals. We analysed context-specific signals in a population Atlantic spotted dolphins around Canary archipelago. calculated whistle diversity, mean value stereotypy repetition rate both tonal burst-pulsed sounds. Eleven parameters frequency, signal duration modulation were measured from each whistle. Results showed that diversity chirp rates negatively correlated with group size, but only...
We studied the soil temperature regimes of volcanic island Tenerife (Canary Islands, Spain), which is situated in Atlantic Ocean between 27 and 28° N. The 2034 km 2 size its highest point 3718 m above sea level. Direct measurements were taken during a 4‐yr period at 103 sites, depth 50 cm, altitudinal sequences from north south slopes island. In contrast to continental situations, all latitudes are found within small area Seven nine considered by Soil Taxonomy have been...
The True's beaked whale (Mesoplodon mirus, True 1913) is a poorly known member of the Ziphiidae family. Its distribution in northern hemisphere thought to be restricted temperate or warm waters North Atlantic, while few stranding records from southern suggest wider and antitropical distribution, extending Atlantic coast Brazil South Africa, Mozambique, Australia Tasman Sea New Zealand. This paper (i) reports first molecular confirmation occurrence at limit its recorded northeast Atlantic:...
On the mountainous islands of Canary Islands (Spain), soils on cool and humid north face are better suited to farming than those hot arid south side. A common practice is transport from one side island other—as well as midaltitude zones in others lower down—to construct artificial known locally sorribas , which used grow, under irrigation, export crops such banana ( Musa acuminata Colla) tomato Solanum lycopersicum L.). The aim this study was evaluate andic properties sorriba derived...
Large areas of the Canarian archipelago are catalogued as aridic according to U.S. soil taxonomy. A traditional system cultivation, based on application a mulch layer tephra, is widely practiced. The objective this work compare classification soils with and without using U. S. taxonomy, illustrate problems in estimating moisture regime basis meteorological data. In study natural an adjacent mulched 12-cm basaltic tephra was characterized gravimetric measurements, taken over period >1 yr, at...
The term iso in soil temperature regimes has been used Soil Taxonomy to distinguish between tropical and temperate zones. It defines with differences of less than 6°C summer (June, July, August) winter (December, January, February). In the northern hemisphere, however, these months are not necessarily warmest coldest months. island Tenerife, which lies 28 29° N near Tropic Cancer, is a transition point regions. trade winds, affecting mainly side island, main reason for presence zone...
Abstract. The volcanic island of Lanzarote (Canary Islands, Spain) is one the most arid parts European Union. During eruptions 1730–36, a third was covered with lava and pyroclastic material. In areas under basaltic tephra, an agrosystem has been developed that allows form dry farming become key component local economy. This article illustrates effectiveness layer natural tephra mulch in conserving soil water.
