  1. Responses of medium- and large-sized bird diversity to irrigation in dry cereal agroecosystems across spatial scales

    Frutos Tena, Ángel de; Olea, Pedro P.; Mateo-Tomás, Patricia
    Conserving biological diversity under agriculture intensification is a global challenge given that the intensification process erodes biodiversity worldwide. Recently, efforts have begun to move towards conserving biodiversity in intensified farmland ecosystems, but there is little understanding of how some kinds of intensification (e.g., irrigation) affect biodiversity. We aimed to assess the responses of farmland bird diversity along an agricultural intensification gradient from dry to irrigation across spatial scales. We covered 10-km-survey transects by car to census medium- and large-sized farmland birds through a decreasing gradient of agricultural intensification ranging from irrigated to dry cereal farming systems in North-western Spain. We...

  2. Conservationists, hunters and farmers: The European rabbit Oryctolagus cuniculus management conflict in the Iberian Peninsula

    Delibes-Mateos, Miguel; Ferreira, Catarina; Rouco, Carlos; Villafuerte, Rafael; Barrio, Isabel C.
    Biodiversity conflicts arise when the interests of different stakeholders over common resources compete. Typically, the more parties involved, the more complex situations become. Resolution of biodiversity conflicts requires an understanding of the ecological, social and economic factors involved, in other words the interests and priorities of each stakeholder. However, in most biodiversity conflicts, many of these components remain poorly understood. As a case study, we analyse the conflict involving conservationists, hunters and farmers in the management of a native lagomorph, the European rabbit Oryctolagus cuniculus, in the Iberian Peninsula. We review the socio-economic context of the rabbit management conflict, investigating...

  3. The role of immigration and local adaptation on fine-scale genotypic and phenotypic population divergence in a less mobile passerine

    García-Navas, Vicente; Ferrer, Esperanza S.; Sanz, Juan José; Ortego, Joaquín
    Dispersal and local patterns of adaptation play a major role on the ecological and evolutionary trajectory of natural populations. In this study, we employ a combination of genetic (25 microsatellite markers) and field-based information (seven study years) to analyse the impact of immigration and local patterns of adaptation in two nearby (< 7 km) blue tit (Cyanistes caeruleus) populations. We used genetic assignment analyses to identify immigrant individuals and found that dispersal rate is female-biased (72%). Data on lifetime reproductive success indicated that immigrant females produced fewer local recruits than their philopatric counterparts whereas immigrant males recruited more offspring than those that...

  4. Lesser protein degradation machinery correlates with higher BM86 tick vaccine efficacy in Rhipicephalus annulatus when compared to Rhipicephalus microplus

    Popara, Marina; Villar, Margarita; Mateos-Hernández, Lourdes; Fernández de Mera, Isabel G.; Marina, Anabel; Valle, Mercedes del; Almazán, Consuelo; Domingos, Ana; Fuente, José de la
    Infestations with cattle ticks, Rhipicephalus (Boophilus) microplus and Rhipicephalus annulatus, economically impact cattle production in tropical and subtropical regions of the world. Vaccines containing the recombinant R. microplus BM86 gut antigen were developed and commercialized to induce an immunological protection in cattle against tick infestations. These vaccines demonstrated that tick control by vaccination is cost-effective, reduces environmental contamination and prevents the selection of drug resistant ticks that result from repeated acaricide applications. The protection elicited by BM86-containing vaccines against tick infestations is mediated by a collaborative action between the complement system and IgG antibodies. The efficacy of the vaccination with...

  6. Trap-effectiveness and response to tiletamine-zolazepam and medetomidine anaesthesia in Eurasian wild boar captured with cage and corral traps

    Barasona, José A.; López-Olvera, Jorge R.; Beltrán-Beck, Beatriz; Gortázar, Christian; Vicente, Joaquín
    [Background]: Capture, handling and chemical restraint are basic techniques often needed for research or management purposes. The aim of this study was testing a combination of tiletamine-zolazepam (TZ) (3 mg/kg) and medetomidine (M) (0.05 mg/kg) on Eurasian wild boar (Sus scrofa). A total of 77 free-ranging wild boar were captured by means of portable cages and corral traps and then anaesthetized with intramuscular darts using a blowpipe. The individual response to chemical immobilization was characterized using anaesthetic, clinical, and serum biochemical variables. After the procedure, 14 of these wild boar were monitored for 20 days using GPS-GSM collars. [Results]: Pre-release...

  7. One Health approach to identify research needs in bovine and human babesioses: workshop report

    Pérez de León, Adalberto A.; Fuente, José de la; Almazán, Consuelo
    Abstract Background Babesia are emerging health threats to humans and animals in the United States. A collaborative effort of multiple disciplines to attain optimal health for people, animals and our environment, otherwise known as the One Health concept, was taken during a research workshop held in April 2009 to identify gaps in scientific knowledge regarding babesioses. The impetus for this analysis was the increased risk for outbreaks of bovine babesiosis, also known as Texas cattle fever, associated with the re-infestation of the U.S. by cattle fever ticks. Results The involvement of wildlife in the ecology of cattle fever ticks jeopardizes...

  8. Temporal stability in the genetic structure of Sarcoptes scabiei under the host-taxon law: empirical evidences from wildlife-derived Sarcoptes mite in Asturias, Spain

    Alasaad, Samer; Oleaga, Álvaro; Casais, Rosa; Rossi, Luca; Molinar Min, AnnaRita; Soriguer, Ramón C.; Gortázar, Christian
    [Background]: Implicitly, parasite molecular studies assume temporal genetic stability. In this study we tested, for the first time to our knowledge, the extent of changes in genetic diversity and structure of Sarcoptes mite populations from Pyrenean chamois (Rupicapra pyrenaica) in Asturias (Spain), using one multiplex of 9 microsatellite markers and Sarcoptes samples from sympatric Pyrenean chamois, red deer (Cervus elaphus), roe deer (Capreolus capreolus) and red fox (Vulpes vulpes). [Results]: The analysis of an 11-years interval period found little change in the genetic diversity (allelic diversity, and observed and expected heterozygosity). The temporal stability in the genetic diversity was confirmed...

  9. Wild boar: an increasing concern for Aujeszky's disease control in pigs?

    Boadella, Mariana; Gortázar, Christian; Vicente, Joaquín; Ruiz Fons, Francisco
    [Background]: The goal of this study was describing the temporal evolution of Aujeszky's disease virus (ADV) contact prevalence among Eurasian wild boar (Sus scrofa) populations under different management regimes and contact likelihoods with domestic pigs. Given the recent increase in wild boar abundance throughout Europe, we hypothesized that wild boar contact with ADV would remain stable in time even after significant reduction of ADV prevalence in domestic pigs. [Results]: Sera from 1659 wild boar were collected from 2000 to 2010 within 6 areas of the Iberian Peninsula and tested for the presence of antibodies against ADV by ELISA. According to...
