The Kiputz IX site records climatic variations during the Late Pleistocene since it represents a continuous time interval record (ca. 25-13ka cal BP). Carbon and nitrogen stable isotopes from the bone collagen of herbivores (Rangifer tarandus, Cervus elaphus, and Bison priscus) were analysed to establish environmental and climatic conditions in the northern Iberian Peninsula. Faunal distribution over time represents a response to climatic variations, showing inverse patterns with reindeer and bison profusion during cold periods and red deer abundance during warmer times. The increase in reindeer δ15N values during stadial GS-2 appears to be greater in magnitude than in continental Europe and reflects drier, warmer climatic conditions. The δ13C values of red deer suggest more humid environmental conditions south of the Pyrenees. During interstadial GS-1 the climatic conditions of southern Pyrenees appear to be analogous to that of northern Pyrenees regions. © 2013 Elsevier Ltd and INQUA.

Over 500 victims of the Spanish Civil War (1936-1939) were buried in the cemetery of La Carcavilla (Palencia, Spain). White material, observed in several burials, was analyzed with Raman spectroscopy and powder XRD, and confirmed to be lime. Archaeological findings at La Carcavillas cemetery show that the application of lime was used in an organized way, mostly associated with coffinless interments of victims of Francoist repression. In burials with a lime cast, observations made it possible to draw conclusions regarding the presence of soft tissue at the moment of deposition, the sequence of events, and the presence of clothing and other evidence. This study illustrates the importance of analyzing a burial within the depositional environment and taphonomic context.

Crimean-Congo hemorrhagic fever virus was detected in ticks removed from migratory birds in Morocco. This finding demonstrates the circulation of this virus in northwestern Africa and supports the hypothesis that the virus can be introduced into Europe by infected ticks transported from Africa by migratory birds.

The genus Anaplasma (Rickettsiales: Anaplasmataceae) includes species of medical and veterinary importance. The presence of Anaplasma spp. in ticks from birds, as well as in Haemaphysalis punctata (Ixodida: Ixodidae) specimens collected from cattle and vegetation in northern Spain was investigated. A total of 336 ticks from birds [174 Ixodes frontalis (Ixodida: Ixodidae), 108 H.punctata, 34 Hyalomma marginatum (Ixodida: Ixodidae), 17 Ixodes ricinus (Ixodida: Ixodidae) and three Ixodes spp.], and 181 H.punctata specimens collected from cattle (n=71) and vegetation (n=110) were analysed. Anaplasma bovis was detected in five H.punctata, including two from birds (1.9%) and three from vegetation (2.7%). Four I.frontalis (2.3%) (one co-infected with Candidatus Midichloria mitochondrii) and one I.ricinus (5.9%) removed from birds, as well as four H.punctata (5.6%) collected from cattle showed Anaplasma phagocytophilum infection. In addition, Anaplasma centrale was found in two H.punctata, one from a cow (1.4%) and the other from vegetation (0.9%). This study represents the first evidence of the presence of A.bovis in European ticks, and reports the first detection of A.bovis and A.centrale in H.punctata, and the first finding of A.phagocytophilum and Ca. Midichloria mitochondrii in I.frontalis.

The genus Borrelia includes species responsible for severe human diseases such as Lyme disease. Birds are involved in their epidemiology as dispersers of infected ticks (Ixodida: Ixodidae) and as reservoirs or amplifiers of the bacterium. Herein, the presence of Borrelia burgdorferi sensu lato (s.l.) Johnson, Schmid, Hyde, Steigerwalt & Brenner in 336 ticks collected from birds in the north of Spain from 2009 to 2011 was investigated. Nucleic acid extracts from 174 Ixodes frontalis (Panzer), 108 Haemaphysalis punctata Canestrini & Fanzango, 34 Hyalomma marginatum Koch, 17 Ixodes ricinus (L.), and 3 Ixodes spp. were screened for the presence of B. burgdorferi s.l. by PCR. Borrelia turdi was detected in 22 I. frontalis, 2 H. punctata, and 2 I. ricinus Additionally, 1 I. frontalis and 1 H. punctata were found to be infected with the human pathogen Borrelia valaisiana Moreover, 3 I. frontalis showed coinfection with both Borrelia species. This study corroborates the presence of B. turdi and B. valaisiana in ticks from birds in the north of Spain. The presence of these bacteria in larval specimens could suggest the role of birds as their reservoirs, or the occurrence of the cofeeding phenomenon. In addition, the detection of B. turdi and B. valaisiana in H. punctata and I. frontalis ticks, respectively, is reported for the first time.

The prevalence of Rickettsia spp. in Ixodes arboricola ticks collected from birds in two locations in the North of Spain from 2011 to 2013 was studied.The detection of the bacteria in 54 DNA extracts of I. arboricola was performed by PCR targeting an ompA fragment gene. The 94.4% of the samples yielded positive results and the nucleotide sequences were homologous (100% identity) to Candidatus Rickettsia vini.The high rate of infection suggests that Ca. R. vini is a common endosymbiont of I. arboricola.

The large morphological variability of Tricholomopsis rutilans sensu lato is assessed through a detailed morphological study and analyses of the ITS-LSU regions. Our Maximum Likelihood and Bayesian analyses coding indel information show that T. rutilans is actually a species complex. Specimens of T. rutilans s.l. form five lineages, all of them characterized by having red-purple tones on the stipe, broadly ellipsoid to subglobose spores, and narrow pleurocystidia 4–7 μm broad. One of those lineages is described as the new species T. pteridicola, collected in the Western Pyrenees, featured by slender fruitbodies with pileus 7–28 mm in diameter, pale yellowish cream lamellae, and by the association with Pteridium aquilinum. Another lineage characterized by large basidiomata, and sometimes scarce to absent pleurocystidia, is identified as T. rutilans s. str. ITS-LSU sequence divergence between European and North American specimens of T. rutilans is high. To stabilize the use of the name T. rutilans, an epitype from Europe is proposed. Tricholomopsis rutilans var. splendidissima is reduced to synonymy with T. rutilans. The other two lineages, referred to as T. aff. rutilans 1 and T. aff. rutilans 2, are at present morphologically not distinguishable from T. rutilans, but appear to have abundant pleurocystidia. We conclude that further morphological and molecular studies are needed in order to formally describe them. © 2015, German Mycological Society and Springer-Verlag Berlin Heidelberg.

We studied the morphology of American mink Neovison vison in five out of the six introduced populations in Spain. The spatial and temporal variation of body weight (BW), body length (BL), tail length, hind-foot length and ear length were analysed. Temporal trends in BW and BL in relation to years since mink introduction were also analyzed. In addition, we tested the effect of sex, age (juvenile, subadult and adult) and age-sex interaction, on each parameter. Morphological parameters differed between populations, illustrating the high variability of body size of American mink in different environments, and the phenotypic plasticity of the species. Annual variations were synchronized between populations, suggesting a large-scale effect on all of them. BW and BL showed a decreasing trend in both males and females in relation to years since introduction. This decrease may be related to mink's diet. Differences in sex and age were found, pointing to sexual dimorphism in adults, subadults and juveniles. The dimorphism in non-adult individuals suggests that subadult males may have a competitive advantage from subadult females in feeding and/or hunting on bigger prey from an early age (resource partitioning hypothesis). © 2012 Deutsche Gesellschaft für Säugetierkunde.

Mycena sect. Calodontes is a taxonomically intricate group comprising phylospecies so far not recognizable using a morphological recognition approach. In this study we re-examine and sequence Iberian material of Porpoloma aranzadii, including the type specimen. The dextrinoid lamellar trama and mycelial hyphae in the type specimen, the latter covered with crystals, suggest a placement in Mycena sect. Calodontes. The type specimen of M. pura f. brunnea is also examined and sequenced. We constructed an ITS dataset representing all European phylospecies reported in previous studies, and we coded indel information. Our phylogenetic analyses recovered strongly supported clades for all the phylospecies and indel information provides additional resolution in phylospecies delimitation. Porpoloma aranzadii sequences are encompassed in the M. dura clade and their synonymy is proposed. Further information on the macroscopic variability of M. dura is obtained. Within sect. Calodontes, M. dura is characterized by the fascicled or caespitose basidiomata, a grassland habitat and sometimes the lack of any raphanoid odour. Its distribution is extended to the Iberian Peninsula. The sequence obtained from the type of M. pura f. brunnea nests in M. pura clade 9. The new combination M. brunnea is proposed to formally refer to this clade at species rank. Mycena brunnea appears to be characterized by a predominantly brown pileus, the absence of deep purple tones and a forest habitat. Mycena brunnea is also macroscopically reminiscent of M. dura, but the former differs mainly in a gregarious growth of basidiomata and a forest habitat. © 2015 Adac. Tous droits réservés.

Abandoned pollard beech forests are particular habitats that may require special conservation efforts to preserve the endangered beetle Rosalia alpina, a model species whose protection may perpetuate the habitat of many other saproxylic species. Forest use can determine the tree selection and population size of R. alpina, variables previously not researched in pollard forests. Selected tree traits and population size, indicated by presence of adult specimens and recent exit holes, were determined in a pollard beech forest before the implementation of habitat manipulations targeted to preserve the species. Multivariate analysis showed tree condition (living, snag, fallen) and clearing size and aspect as influential variables, with the former explaining more variance than the latter. R. alpina positively selected pollard snags and trees located in big and dry clearings, avoiding those in small clearings or shaded areas. Snags showed most adults (90 %) and recent emergence holes (84 %). Distance to the nearest occupied tree, trunk diameter, bark thickness and presence of sap leaks had no effect on the occurrence of R. alpina. Population size was estimated in 0.1 individuals day−1 ha−1, and 38 % of available habitat trees showed exit holes, values lower than those observed in other European countries. These results show the need to start re-pollardings in the forest to extend pollard standing life and enhance exposure to sunlight. Pinpointing pollard snags and clearing the surrounding vegetation are recommended as the first measures to be taken in order to favor R. alpina populations on pollard stands with closed canopies. © 2016 Springer International Publishing Switzerland
