Heartworm disease is a vector-borne zoonotic caused by Dirofilaria immitis. The Canary Islands (Spain), geolocated close to the coast of Western Sahara, an archipelago considered hyperendemic where average prevalence in domestic dogs high, heterogeneous, and non-uniform. In addition, Culex theileri has been reported as vector on two most populated islands. Our aim was develop more accurate transmission risk model for dirofilariosis Islands. For this purpose, we used different variables...

Canine leishmaniosis, caused by the protozoan parasite Leishmania infantum , is a cosmopolitan vector-borne zoonosis, transmitted principally Phlebotomus perniciosus in Spain and Portugal, where it considered an endemic disease. Ecoinformatics tools such as ecological niche models (ENM) have been successfully tested to model distribution of risk infection different parasitosis they take into account environmental variables vital for their survival. The map proposed this study combines...

Various factors are currently causing an increase in vector-borne parasitic diseases at a global scale; among them, some stand out, such as climatic disturbances derived from change, the movements of reservoir animals, or changes land made by human activity. In European continent, there have been increasing number epidemiological studies focused on detection these diseases, especially dogs. Spain, few evaluation biotic and abiotic that may influence distribution, zones, orography, presence...

Abstract Pollen grains of 30, mainly annual, species from 134 populations the genus Veronica (Plantaginaceae, formerly Scrophulariaceae) Mediterranean Region, have been studied with light and scanning electron microscopy. Three pollen types are defined based on size exine surface sculpture. In some cases within study group can be useful in determination. Hypothetical relationships grain aperture number ploidy level, style length corolla diameter discussed. The ornamentation Veronica,...

A palynological study by LM and SEM was made of 26 taxa Potentilla L. subg. Potentilla. It is more precise on material from 110 populations, mainly the western Mediterranean. On basis morphometry, can be said to have a stenopalynous nature, due absence significant differences between studied high degree overlapping shown their range variation. With respect ornamentation, which striate, only P. rupestris pollen separately identified much marked striation than other species studied. An attempt...

Biogeographical theory suggests that widespread retractions of species’ rear edges are expected due to anthropogenic climate change, affecting in a particularly intense way those linked fragile habitats, such as closely dependent on specific water conditions. In this way, paper studies the potential effects change distribution patterns threatened edge populations five European hydrophyte plants distributed Iberian Peninsula. We explored (i) whether these occur at limit climatic tolerance,...

Abstract During a taxonomic revision of the genus Veronica L. for Flora iberica project, an attempt was made to fix correct status names cited in study area. With this aim, here we have designated lectotypes, neotypes and epitypes 18 previously untypified names, mainly belonging annual species, some them widely distributed such as V. persica praecox . These newly proposed types support current use concerned therefore contribute establishing nomenclature genus.

Climate change has emerged as the main threat to global biodiversity and even protected areas (PAs) are not immune this problem. Here, we have focused on PAs with aim of assessing impacts climate their habitat suitability effectiveness protect threatened species, in case three endemic Spanish plants: Isatis platyloba, Rhaponticum exaltatum Succisella microcephala. We used machine-learning technique called Maxent that is able potential species distribution under four future scenarios. Our...

The current situation of global environmental degradation as a result anthropogenic activities makes it necessary to open new research lines focused on the causes and effects main alterations caused in ecosystems. One most relevant is how niche dynamics invasive species change between different geographical areas, since its understanding key early detection control future invasions. In this regard, we analyzed distribution pattern Cirsium vulgare (Savi) Ten., plant Asteraceae family...

Ecological drivers for genetic differentiation in Mediterranean climates are still underexplored. We have used the strictly endemic Odontites recordonii as a model species to address this question. This is one of three Iberian representatives O. vernus group, which morphologically similar. Thus, it was additionally necessary clarify their phylogenetic relationships.We amplified fragment length polymorphisms reveal relationships within and reconstruct phylogeographic patterns recordonii....

Las plantas vasculares que no forman semillas son conocidas con el nombre vulgar de helechos, presentando unas 120 especies en la península ibérica, más abundantes ambientes forestales húmedos y saxícolas. En entornos urbanos semiurbanos suelen ser muy numerosos, un hecho parece estar unido a escasa presencia sus esporas atmósfera estas zonas, comparación otras partículas biológicas como las fúngicas o los granos polen. El objetivo este trabajo es proporcionar una clave determinación tipos...

Astragalus devesae Talavera, A. González & G. López (Fabaceae) is a threatened Hispanic endemic species whose distribution restricted to the center of Spain (the province Ávila). It classified as ?Critically Endangered? in 2010 List Threatened Spanish Vascular Flora and ?Endangered? ?Decree 63/2007? Castile Leon (administrative region which Ávila included). In this study, censuses three existing populations were carried out one these that was found along course work, ecologically...
