We analyzed the distribution of genetic variation at 6 microsatellite loci in heavily hunted populations red deer (Cervus elaphus) southwestern Spain. Some hunting estates are surrounded by high mesh fences that prevent from leaving estate. The primary purpose our study was to assess whether differences exist degree fenced versus open estates, as well between comparison with a protected population Donana National Park. Another estimate extent differentiation. There is significant subdivision...
Abstract Background Currently, many micromammals are important targets for study. The endangered Galemys pyrenaicus is an outstanding example. Globally, their populations have suffered a substantial decline in last 20 years. In the surveyed area, capture of desman legally forbidden due to high conservation concerns. Reason by non-invasive sampling through faeces proposed its monitoring. Furthermore, confusion between from and Mediterranean water shrews must be considered. Thus, aim this...
Equine piroplasmoses are enzootic parasitic diseases distributed worldwide with high incidence in tropical and subtropical regions. In Spain, there is insufficient epidemiological data about equine piroplasmoses. The main aim of the present study was therefore to estimate prevalence Theileria equi Babesia caballi five regions obtain information risk factors. This conducted central south-western using indirect fluorescence antibody testing (IFAT) 3,100 sera samples from apparently healthy...
Typically, carnivores serve as definitive hosts for Sarcocystis spp. parasites; currently, their role intermediate is being elucidated. The present study aimed to identify and molecularly characterize cysts detected in striated muscle of red foxes from different populations Latvia, Lithuania Spain. Muscle samples 411 (Vulpes vulpes) 269 racoon dogs (Nyctereutes procyonoides) 41 22 Spain were examined the presence sarcocysts by light microscopy (LM). identified transmission electron (TEM)...
Dictyocaulosis is a parasitic disease affecting ungulate species, including red deer (Cervus elaphus). Dictyocaulus genus consist of nine species but only four are reported to infect deer. The characterized by respiratory tract infection, particularly in lungs, bronchi and bronchioles, causing inflammatory hemorrhagic microscopic lesions also emphysema edema. Biological cycle consists female that oviposits larvae eggs the trachea be expelled exterior coughing releasing L1 environment. In...
Abstract The occurrence and molecular diversity of the stramenopile eukaryote Blastocystis sp. was investigated by PCR sequencing (Sanger NGS ) methods in 380 faecal specimens free‐living carnivores Spain. confirmed 1.6% (6/380) analysed. Two samples from a common genet fox were successfully subtyped as ST 7 Sanger. Using , 14 found European polecat, fox, two additional foxes presented mixed infections 1/ 2/ 4 7, respectively. Wild carnivore species could act carriers zoonotic subtypes.
Deer antlers are costly structures subjected to directional sexual selection that may be sensitive heterozygosity. However, a relationship between heterozygosity and antler development has only been found for select protein-coding loci MHC genes in one deer species (the white-tailed Odocoileus virginianus). Here, we study the multilocus at 11 microsatellite markers size (AS) sample of 367 Iberian red males (Cervus elaphus hispanicus) from two areas with different ecological genetic...
The Iberian desman (Galemys pyrenaicus) is a small semi-aquatic mammal that inhabits mountainous areas from the centre to north of Peninsula and Pyrenees listed as endangered because it has suffered serious decline. Since 1960, only three species digeneans (Omphalometra flexuosa, Maritrema pyrenaica Mathovius galemydis) two nematodes (Aonchotheca galemydis Paracuaria hispanica) have been reported desman, but no further information on health status data Extremadura available. aim our study...
Abstract The European wildcat ( Felis silvestris ) is a mesocarnivore species widely distributed in Europe, from Eastern Europe to Portugal and Scotland Italy. Recent biogeographical studies of populations have endeavoured assess detail the various issues that pose threat this species, including hybridization with domestic cats. use non-invasive sampling methods supported by photo-trapping some attractants has made it possible gather genetic material for detection native wildcats locally...
Offspring quality may benefit from genetic dissimilarity between parents. However, trade-off with additive benefits. We hypothesized that when sexual selection produces sex-specific selective scenarios, the relative benefits of vs. differ for sons and daughters. Here we study a sample 666 red deer (Cervus elaphus) microsatellite genotypes, including males, females their foetuses, 20 wild populations in Spain (the main analyses are based on 241 different foetuses 190 mother-foetus pairs)....
The Persian fallow deer ( Dama dama mesopotamica ) formerly widespread in the Middle East was described scientifically at end of 19th century and considered extinct ever since. In 1956 it rediscovered south-western Iran. As a result, several countries have undertaken actions to reintroduce this subspecies its native territory. 2007 Christian Oswald Foundation, close cooperation with Iranian institutions, launched plans situ ex breeding actions, centre German Von Opel Zoo cooperative...
Abstract In recent years it has been claimed that the introduction of invasive species significantly damages ecosystems. Their ability to adapt overestimated, without considering consequences they could have on native fauna. One clearest examples is American mink (Neovison vision), which also postulated as a large predator. Its diet includes small mammals such Mediterranean water shrew (Neomys anomalus), one great importance, Iberian desman (Galemys pyrenaicus), today seriously endangered...
Beginning with a description of the conventional Giemsa-stained karyotype tench (<i>Tinea tinea </i>L.), structure and variability chromosomal heterochromatic regions in this cyprinid species were analyzed by means C-, silver-, restriction endonuclease banding. Silver staining revealed active nucleolus organizer (NORs) on secondary constriction chromosome pair 3. Constitutive heterochromatin was associated NOR detected C-banding. Restriction digestion <i>Alu</i>I,...
ABSTRACT Desmans belong to the subfamily Desmaninae, which are members of family Talpidae. and moles show limited sexual dimorphism, making unclear sex discrimination by phenotypic assessment. The Iberian desman ( Galemys pyrenaicus ) is an endangered species with a severe population decline. Knowledge ratio essential for conservation management. Based on these arguments although previous conventional PCR studies amplifying DBX/DBY genes were relatively successful in sexing desman,...
Abstract Background Wildlife conservation and management aims to restore population declines, it is the vulnerable or endangered populations who require greatest efforts. In this context, non-invasive sampling has been evaluated as an option for reporting prey/predator impact. Galemys pyrenaicus currently threatened throughout its range, cohabits with Nemys anomalus , in Extremadura (Spain). Predation by American mink otter suggested, but first one considered a serious problem. This study...
Management of game species may involve a risk alteration their genetic properties. Local adaptations be disrupted if artificially selected individuals from farms or those belonging to distant geographical areas are introduced increase population density trophy ‘quality’. In Spain, red deer (Cervus elaphus) different European subspecies have been the size trophies (antlers) local populations. Legislation against these introductions is not effective for various reasons, and once in Iberian...
Numerous studies have unsuccessfully tried to unravel the definitive host of coccidian parasite Besnoitia besnoiti. Cattle infections by B. besnoiti cause a chronic and debilitating condition called bovine besnoitiosis that has emerged in Europe during last two decades, mainly due limitations its control associated with absence vaccines therapeutical tools. Although exact transmission pathways is currently unknown, it assumed might an indirect life cycle carnivore as host. Current lack...
