Polyandry and non-random fertilisation maintain long-term genetic diversity in an isolated island population of adders (Vipera berus)
<p>Conservation genetic theory suggests that small and isolated populations should be subjected to reduced genetic diversity i.e., heterozygosity and allelic diversity. Our 34 years study of an isolated island population of adders (<em>Vipera berus</em>) in southern Sweden challenges this notion. Despite a lack of gene flow and a yearly mean estimated reproductive adult population size of only 65 adult adders (range 12 to 171), the population has been able to maintain high levels of heterozygosity and allelic diversity similar to that observed in two mainland populations. Even a 14-year major "bottleneck" i.e., a reduction in adult adder numbers, encompassing at least four adder generations, did not result in any reduction in the island adders' heterozygosity and allelic diversity. Female adders are polyandrous, and fertilisation is non-random, which our empirical data and modelling suggest underpinning the island adders' ability to maintain a high level of heterozygosity. Our empirical results and subsequent modelling suggest that the positive genetic effects of polyandry in combination with non-random fertilisation, often overlooked in conservation genetic analyses, deserve greater consideration when predicting long-term survival of small and isolated populations.</p>

Adders are Amazing project evaluation of attitudes and connectedness to nature
<ol> <li>Adder <em>(Vipera</em> <em>berus</em>) populations are experiencing declines in many countries, including the UK. Perceptions of adders and other venomous snakes are generally negative, making conservation of these species a challenge, and persecution remains within the top five perceived causes for adder declines in the UK. Improved understanding and attitudes are needed to support current conservation efforts. However, ensuring these positive attitudes continue into the future relies on addressing children's loss of connection to nature, and intervention at this early attitude-formation stage can be crucial for traditionally 'unpopular' species, such as snakes.</li> <li>An adder-focussed public-engagement project, Adders are Amazing!, was carried out in Pembrokeshire, UK, in 2018–19 to improve understanding and attitudes towards adders using a blended science-creative arts approach. The project included half-day primary school-based workshops to inform 111 pupils aged 8 to 11 about adder ecology, alongside creative art experiences. Questionnaires were used to measure the children's attitudes towards adders and their nature connectedness both before and after the workshops and these were compared with equivalent questionnaires carried out at a control school (57 pupils) where no workshops were conducted. </li> <li>The project demonstrated that engagement that blends both art and science can significantly change attitudes towards adders without any direct contact with the animals themselves; specifically, participants' scores for 'Wonder', 'Learning Interest' and 'Conservation Concern' increased. The workshops also significantly increased measures of the children's general connectedness to nature (specifically, 'Enjoyment of Nature' and 'Responsibility for Nature').</li> <li>We recommend conservation bodies focus on, and not shy away from, so-called 'unpopular' species, to promote understanding and acceptance of these species and support their conservation. Blended arts-science initiatives, which can be easily adapted to suit a wide range of species and the artistic practices of local communities, are an effective way to achieve this.</li> </ol>

Data from: Postglacial recolonisation in a cold climate specialist in Western Europe: patterns of genetic diversity in the adder (Vipera berus) support the central-marginal hypothesis
Understanding the impact of postglacial recolonization on genetic diversity is essential in explaining current patterns of genetic variation. The central–marginal hypothesis (CMH) predicts a reduction in genetic diversity from the core of the distribution to peripheral populations, as well as reduced connectivity between peripheral populations. While the CMH has received considerable empirical support, its broad applicability is still debated and alternative hypotheses predict different spatial patterns of genetic diversity. Using microsatellite markers, we analysed the genetic diversity of the adder (Vipera berus) in western Europe to reconstruct postglacial recolonization. Approximate Bayesian Computation (ABC) analyses suggested a postglacial recolonization from two routes: a western route from the Atlantic Coast up to Belgium and a central route from the Massif Central to the Alps. This cold-adapted species likely used two isolated glacial refugia in southern France, in permafrost-free areas during the last glacial maximum. Adder populations further from putative glacial refugia had lower genetic diversity and reduced connectivity; therefore, our results support the predictions of the CMH. Our study also illustrates the utility of highly variable nuclear markers, such as microsatellites, and ABC to test competing recolonization hypotheses.
Data from: Do newborn adders suffer mass mortality or do they venture in a collective hide-and-seek game?
In long-lived snakes estimates of survival rates in the immature age classes are notoriously difficult to obtain because the small, secretive juveniles are rarely caught in field studies. Hence, it is assumed that in many species juveniles suffer high mortality. An alternative view holds that the youngest life stages are so elusive as if they "disappear" temporarily from the population. We conducted a long-term (2000-2016) mark-recapture study in a large population of European adders and obtained demographic data for large numbers of immature and newborn snakes. Estimates obtained by the Cormack-Jolly-Seber (CJS) method revealed dramatic age-related differences in yearly capture probabilities: they were much lower in the immature classes than in the adults. Concurrently , we found no evidence for age-dependent differences in survival rates. Hence, our inability to capture large numbers of immature snakes should therefore be attributed to their low detection probabilities, not because they would suffer high post-natal mortality. At least three traits contribute to the poor detectability of the immature snakes: (1) their small body size, (2) their lower thermal requirements, and (3) their non-permanent emigration to the "summer" or foraging habitats, which possess a greater food supply than the "winter" habitats.
