    ABSTRACT Populations of the European brown bear (Ursus [1], Depending on availability and quality hairs with visible roots were used, DNA extractions from non-invasive samples were performed with the QIAamp DNA Stool Kit (QIAGEN) with a final elution volume of 100 μl. Microsatellites Analysis and Gender Identification Seven microsatellite loci Mu26, Mu64, G10B, G1D, G10L, Mu50 and Mu51 were amplified using polymerase chain reaction [2] and fragment length (allele) analyses were carried out on eight-capillary sequencer (Genome Lab GeXP, BeckmanCoulter). Analyses were repeated in order to verify the reliability of individual allele length determination. DNA was extracted from hair using 10% Chelex solution [25] and from faeces with the Qiamp DNA Stool® kit (Qiagen). To test for individuals, seven microsatellite loci (UaMU26, UaMU64, G10B, G1D, G10L, UaMU50 and UaMU51) were amplified in a nested polymerase chain reaction (PCR) [2]: a longer fragment of each locus was amplified prior to amplifying a more specific area. Two-step PCR procedures improve genotyping success rate and limit genotyping errors Statistical Methods Observed (H O ) and expected (H E ) heterozygosity were calculated with CERVUS software. Descriptive statistics for each locus (mean number of alleles per locus, heterozygosities and polymorphic information content (P IC ) were computed from allele frequencies. The Fisher's exact test was used to check for genotypic linkage disequilibrium for all pairs of loci by employing the Markov chain method, as implemented in GENEPOP Results The mean observed heterozygosity (

    A comprehensive systematic review of stakeholder attitudes to alternatives to prospective informed consent in paediatric acute care research

    Background: A challenge of performing research in the paediatric emergency and acute care setting is obtaining valid prospective informed consent from parents. The ethical issues are complex, and it is important to consider the perspective of participants, health care workers and researchers on research without prospective informed consent while planning this type of research. Methods: We performed a systematic review according to PRISMA guidelines, of empirical evidence relating to the process, experiences and acceptability of alternatives to prospective informed consent, in the paediatric emergency or acute care setting. Major medical databases and grey sources were searched and results were screened and assessed against eligibility criteria by 2 authors, and full text articles of relevant studies obtained. Data were extracted onto data collection forms and imported into data management software for analysis. Results: Thirteen studies were included in the review consisting of nine full text articles and four abstracts. Given the heterogeneity of the methods, results could not be quantitatively combined for meta-analysis, and qualitative results are presented in narrative form, according to themes identified from the data. Major themes include capacity of parents to provide informed consent, feasibility of informed consent, support for alternatives to informed consent, process issues, modified consent process, child death, and community consultation. Conclusion: Our review demonstrated that children, their families, and health care staff recognise the requirement for research without prior consent, and are generally supportive of enrolling children in such research with the provisions of limiting risk, and informing parents as soon as possible. Australian data and perspectives of children are lacking and represent important knowledge gaps

    Wildlife damage to human property threatens human-wildlife coexistence. Conflicts arising from wildlife damage in intensively managed landscapes often undermine conservation efforts, making damage mitigation and compensation of special concern for wildlife conservation. However, the mechanisms underlying the occurrence of damage and claims at large scales are still poorly understood. Here, we investigated the patterns of damage caused by brown bears Ursus arctos and its ecological and socio-economic correlates at a continental scale. We compiled information about compensation schemes across 26 countries in Europe in 2005-2012 and analysed the variation in the number of compensated claims in relation to (i) bear abundance, (ii) forest availability, (iii) human land use, (iv) management practices and (v) indicators of economic wealth. Most European countries have a posteriori compensation schemes based on damage verification, which, in many cases, have operated for more than 30 years. On average, over 3200 claims of bear damage were compensated annually in Europe. The majority of claims were for damage to livestock (59%), distributed throughout the bear range, followed by damage to apiaries (21%) and agriculture (17%), mainly in Mediterranean and eastern European countries. The mean number of compensated claims per bear and year ranged from 0·1 in Estonia to 8·5 in Norway. This variation was not only due to the differences in compensation schemes; damage claims were less numerous in areas with supplementary feeding and with a high proportion of agricultural land. However, observed variation in compensated damage was not related to bear abundance. Synthesis and applications. Compensation schemes, management practices and human land use influence the number of claims for brown bear damage, while bear abundance does not. Policies that ignore this complexity and focus on a single factor, such as bear population size, may not be effective in reducing claims. To be effective, policies should be based on integrative schemes that prioritize damage prevention and make it a condition of payment of compensation that preventive measures are applied. Such integrative schemes should focus mitigation efforts in areas or populations where damage claims are more likely to occur. Similar studies using different species and continents might further improve our understanding of conflicts arising from wildlife damage

    Exchanging experience and finding solutions to problems facing the use of livestock guarding dogs (LGDs) in modern societies were among the goals of a meeting organized in Portugal from 20th to 21st October 2015 within the scope of the LIFE MedWolf Project (www.medwolf.eu). The meeting was attended by 16 specialists from around Europe (Portugal, Spain, France, Switzerland, Italy, Croatia, Slovakia and Bulgaria), as well as from Australia and the USA. In this article we outline constraints on the use of LGDs identified during the meeting and summarize the main solutions proposed. We have grouped the issues into 10 main topics ranging from a lack of quality dogs to personal, social, cultural, economic, time, management, technical, legal and political constraints. Guidelines on the proper raising and caring of LGDs are not the focus of this article, since a great deal of information is already available, including on specific solutions to common problems

    Phenology of brown bear breeding season and related geographical cues

    Knowledge about breeding biology is often incomplete in species with complex reproductive strategies. The brown bear Ursus arctos is a polygamous seasonal breeder inhabiting a wide variety of habitats and environmental conditions. We compiled information about brown bear breeding season dates from 36 study areas across their distribution range in the Palearctic and Nearctic regions and investigated how their breeding phenology relates to geographical factors (latitude, photoperiod, altitude and region). Brown bear matings were observed for 8 months, from April to November, with a peak in May%July. We found a 59-day difference in the onset of bear breeding season among study areas, with an average 2.3 days delay for each degree of latitude northwards. The onset of the breeding season showed a strong relationship with photoperiod and latitude, but not with region (i.e. Palearctic vs Nearctic) and altitude. First observa- tions of bear mating occurred earlier in areas at lower latitudes. Photoperiod ranged between 14 and 18 hours at the beginning of the season for most of the study areas. The duration of the breeding season ranged from 25 to 138 days among study areas. None of the investigated factors was related to the length of the breeding season. Our results support the relevance of photoperiod to the onset of breeding, as found in other ursids, but not a shorter breeding season at higher latitudes, a pattern reported in other mammals. Our findings suggest a marked seasonality of bear reproductive behaviour, but also certain level of plasticity. Systematic field observations of breeding behaviour are needed to increase our knowledge on the factors determining mating behaviour in species with complex systems and how these species may adapt to climate change

    Protocol: a comprehensive systematic review of alternatives to prospective informed consent in paediatric emergency research

    No full text
    There is a community expectation that children presenting to emergency departments receive the best possible care, and that decisions are based on high-level evidence. Clinical research in children is necessary for paediatric emergency medicine to continue to advance, but research in emergency settings is challenging. One of the many challenges researchers face in conducting emergency research is the difficulty of obtaining prospective informed consent in ED research, and this has historically been a barrier to conducting research in this setting. Guiding principles for use of alternatives to prospective informed consent in emergency research are outlined in the Declaration of Helsinki and in local documents such as the NHMRC National Statement on Ethical Conduct in Human Research which allows consent to occur after an intervention in certain circumstances. To ensure that ethical research can continue to be performed in this group, within the expatiations of the community, it is important to explore and understand the perceptions and experiences of parents, health care workers and researchers to alternatives to informed consent in paediatric emergency research

    Non-consumptive use of wolves in tourism: guidelines for responsible practices [Large Carnivore Initiative for Europe IUCN/SSC Specialist Group] Specialist Group

    In many early European cultures, humans shared an overall positive view of the wolf (Boitani, 1995; Boitani and Ciucci, 2009). But this changed with the anthropocentric view of nature brought about by Christianity as well as with the process of domestication and the advent of extensive animal husbandry (Boitani, 1995). Wolves were then strongly persecuted, leading to their extirpation in almost all their former range across the continent. In the last few decades, however, wolves have returned to many parts of Europe from which they had been absent for centuries. Their recovery impacts a range of human activities and interests and is accompanied by a variety of social conflicts and diverging points of view on how wolves should be managed (Boitani and Linnell, 2015; Linnell and Cretois, 2018). Conflicts and the negative economic impacts of wolf damage to livestock are the most pressing problems for wolf management today. Public debate and academic research on wolf–human relations tend to focus on these issues (Rode et al., 2021). The ecological roles of wolves in ecosystem structure and functioning are increasingly recognized (Hebbelwhite et al., 2005; Kuijper et al., 2013). However, although predator-prey interactions are highly contextdependent, most studies on this topic have been undertaken in large, natural landscapes. In most of Europe, human actions attenuate the ecological effects of large carnivores (Kuijper et al., 2016). Nevertheless, new values and the potential social benefits of human–wolf coexistence are underappreciated. Wolves are an important generator of culture, ethnography and tradition (Álvares et al., 2011) and their presence brings educational and research benefits, income from regional and product marketing, as well as socio-economic benefits from wildlife tourism (Rode et al., 2021). Different forms of tourism associated with wolves, such as wolf watching, photographing, or observing signs of their presence have already been practiced for a couple of decades in North America (Wilson and Heberlein, 1996) and to a lesser extent in Europe (Koščová and Koščová, 2016; Bavo and Villar Lama, 2020; Notaro and Grilli, 2021). Although tourism can increase the value of the species locally, such activities can also have negative impacts on wolves and their habitat, especially with the growing demand for wildlife tourism (Curtin and Kragh, 2014). The following guidelines were prepared by members of the LIFE WOLFALPS EU project group and the Large Carnivore Initiative for Europe expert group of the IUCN/SSC to set specific recommendations for responsible non-consumptive use of wolves in tourism which has as little impact on wolves as possible. The aim of these guidelines is to promote tourism activities that go beyond direct sightings of wildlife by focusing on wolf presence and wolf-related cultural heritage, creating economic opportunities for local communities in areas with wolves and consequently leading to increased tolerance towards this species
