Two different ethical notions of benefit sharing of genetic resources and their implications for global development

Nazi eugenics is one of the main historical events influencing current popular as well as scholarly discussions of reproductive genetics. This influence, however, is open to different interpretations and social constructions. Based on 44 open interviews with Israeli and German genetic counselors, conducted in 2000–2003, our findings suggest that while the majority of German counselors reflected on Nazi eugenics as setting moral limits for contemporary repro-genetics, many Israeli counselors detached their contemporary practice from the wrongdoings of the past. Correspondingly, German counselors were far more sensitive towards the disability critique of repro-genetics than their Israeli counterparts. We conclude with a discussion of these two opposite positions, suggesting that the comparison of German and Israeli professionals reveals a profound complexity and involvedness in coming to terms with the “eugenic” lessons of the Holocaust, on both sides. In Germany, potential benefits of repro-genetics might be rejected due to an emphasis on a more universalistic lesson of the Holocaust regarding the value of human life and dignity. In Israel, a more particularistic lesson of the Holocaust regarding national Jewish survival, combined with a lack of public debate regarding medicalization and geneticization, might have promoted the advent of unregulated commercially and consumer-driven repro-genetics.     

Computational Reproducibility in The Wildlife Society's Flagship Journals

Scientific progress depends upon the accumulation of empirical knowledge via reproducible methodology. Although reproducibility is a main tenet of the scientific method, recent studies have highlighted widespread failures in adherence to this ideal. The goal of this study was to gauge the level of computational reproducibility, or the ability to obtain the same results using the same data and analytic methods as in the original publication, in the field of wildlife science. We randomly selected 80 papers published in the Journal of Wildlife Management and Wildlife Society Bulletin between 1 June 2016 and 1 June 2018. Of those that were suitable for reproducibility review (n = 74), we attempted to obtain study data from online repositories or directly from authors. Forty-two authors did not respond to our requests, and we were further unable to obtain data from authors of 13 other studies. Of the 19 studies for which we were able to obtain data and complete our analysis, we judged that 13 were mostly or fully reproducible. We conclude that the studies with publicly available data or data shared upon request were largely reproducible, but we remain concerned about the difficulty in obtaining data from recently published papers. We recommend increased data-sharing, data organization and documentation, communication, and training to advance computational reproducibility in the wildlife sciences. © 2020 The Authors.

Attitudes toward Post‐Trial Access to Medical Interventions: A Review of Academic Literature,Legislation, and International Guidelines

There is currently no international consensus around post‐trial obligations toward research participants, community members, and host countries. This literature review investigates arguments and attitudes toward post‐trial access. The literature review found that academic discussions focused on the rights of research participants, but offered few practical recommendations for addressing or improving current practices. Similarly, there are few regulations or legislation pertaining to post‐trial access. If regulatory changes are necessary, we need to understand the current arguments, legislation, and attitudes towards post‐trial access and participants and community members. Given that clinical trials conducted in low‐income countries will likely continue, there is an urgent need for consideration of post‐trial benefits for participants, communities, and citizens of host countries. While this issue may not be as pressing in countries where participants have access to healthcare and medicines through public schemes, it is particularly important in regions where this may not be available.     

Speciation and periodic restricted environments. The case of genus Ononis L. (subsections Natrix and Viscosae)

The morpho–environmental similarity between subsections Natrix and Viscosae has been pointed out as the reason for the genetic complexity of these groups of taxa. Based on this characterization a question emerges: could a very recent ongoing evolutionary process explain that morpho–environmental similarity? ISSR and cpSSR amplifications for 45 specimens belonging to taxa of Natrix and Viscosae subsections were developed, along their biogeographic distribution areas. Twenty-nine haplotypes were detected in the biogeographic area of both subsections, 79% were exclusive haplotypes, but the rest is shared between subsections Natrix and Viscosae species. Could that haplotype sharing be the result of potential hybridization between these taxa? Do current environmental conditions restrict the gene flow among taxa? The combination of ancestral genetic polymorphism, introgression, coalescence processes and periodic restricted environments (PRE) by glacial–interglacial environmental dynamics were discussed to explain the relevant percentage of exclusive haplotypes detected, as well as the persistence of shared haplotypes. These results are in accordance with the morpho–environmental proximity previously described for both subsections.     

Expert assessment of landscape-level conservation strategies in boreal forests for biodiversity,recreation and water quality

Determining effects of landscape-level conservation strategies is needed, yet a challenging and costly endeavour. The aim of this study was to evaluate the effects of landscape-level conservation strategies in forests on biodiversity and provision of two ecosystem services (recreation and water quality). Specifically, we focused on the spatial allocation of unmanaged areas in production forests and different levels of “land sharing” or “land sparing”. They were represented through seven scenarios constructed for a boreal managed forest landscape in central Sweden. All scenarios had the same total level of conservation effort, but they differed in the combinations of sizes of unmanaged areas and how these areas were spread in the landscape. In one scenario, this was complemented with extended rotation of production areas. Experts (researchers in relevant fields) assessed these scenarios for overall biodiversity, recreation, and water quality. We used the Delphi technique: experts filled out an online survey individually in two rounds. In the second round they were familiarized with anonymized responses of others from the previous round. There was little agreement between experts whether concentration of unmanaged areas in one part of the landscape or dispersion of them around the entire area is more beneficial, for biodiversity as well as for the two ecosystem services. The explanation of the opinions given by biodiversity experts were based on different ecological theories resulting in different conclusions (mainly habitat complementation vs. metapopulation ecology). A few large unmanaged areas were considered more beneficial for biodiversity than many small areas. The main argument was that long-term species persistence becomes higher with larger areas. For recreation and water quality, there were almost no differences in estimates between these two strategies. One “land sharing” approach, retention trees, received the lowest score. The second “land sharing” approach, extended rotation, was scored higher, especially regarding recreation. This may be because extended rotations generate features of high recreational value, such as mature, thinned forests with not so much dead wood. Conclusively, we suggest a strategy of mixed conservation measures, with considerable efforts directed towards establishing and maintaining large unmanaged areas.

Habitat characteristics and species interference influence space use and nest‐site occupancy: implications for social variation in two sister species

Nest‐site selection is an important component of species socio‐ecology, being a crucial factor in establishment of group living. Consequently, nest‐site characteristics together with space‐use proxies may reveal the social organization of species, which is critical when direct observation of social interactions is hindered in nature. Importantly, nest‐site choice is expected to be under strong selective pressures and the object of intra‐ and interspecific competition. Although the bulk of research on sociality focuses on its ecological drivers, our study introduces interspecific competition as a potential factor that could influence social evolution. We investigated the influence of habitat and interspecific competition on the social organization of two sister species of the African four striped mouse, Rhabdomys dilectus dilectus and Rhabdomys bechuanae, in a similar macroenvironment. These species diverged in allopatry and occupy distinct environmental niches. We radiotracked 140 adults to identify their nest‐sites, determine nest characteristics and record groups that shared nest‐sites. Group cohesion was estimated from nest‐site fidelity, group association strength, and home range overlap within versus between group members. We compared the two species in sympatry versus parapatry to determine the impact of species interference on sociality. In parapatry, the two species selected distinct nest‐site types, interpreted as different anti‐predator strategies: R. bechuanae selected fewer, spaced, less concealed nest‐sites whereas R. d. dilectus selected clumped and less visible nest‐sites. Rhabdomys bechuanae also showed more cohesive and stable social groups than R. d. dilectus. In sympatry, compared to R. bechuanae, R. d. dilectus occupied similar nest‐sites, however slightly more exposed and clumped, and displayed similar nest‐site fidelity and group association strength. We conclude that although habitat selection may be an important driver of social divergence in Rhabdomys, species interference, by limiting R. d. dilectus movements and forcing nest‐site sharing may induce new ecological pressures that could influence its social evolution.     

Food sharing and affiliation: An experimental and longitudinal study in cockatiels (Nymphicus hollandicus)

Food sharing has attracted much attention because of its apparently altruistic nature and its link to prosociality. However, food sharing has been mostly studied in a reproductive context, during courtship and parental care, where the fitness benefits are obvious. We still lack a clear understanding of the functions of food sharing outside any reproductive context and within social groups of same‐aged peers. Previous studies suggest that cofeeding, the action to let another animal feed from the same monopolizable food source, may be used to build and strengthen bonds between individuals. This may be particularly crucial in social birds forming long‐term associations between mates or siblings such as psittacids and corvids. Here, we investigated food sharing and affiliative behaviors such as allopreening in a psittacine species, namely in a group of captive juvenile cockatiels (Nymphicus hollandicus) consisting of five siblings and five unrelated birds. Our main objective was to study the developmental pattern of food sharing over time and its implication in social bonding depending on kinship, affiliation, and sex. Studying cockatiels in this context is providing many new information since most of the studies on food sharing in birds focused on corvids. We found that, contrary to jackdaws, cockatiels continued to share food with multiple individuals, although the frequency of cofeeding as well as the number of cofeeding partners decreased over time. Cockatiels shared more food with their siblings than with other conspecifics but they were not more likely to do cofeeding with birds of the opposite sex. We also found evidence that young cockatiels exchanged more food with those from whom they received food (reciprocity) and, to a lesser extent, allopreening (interchange), than from other cockatiels. Our findings suggest that in cockatiels, food sharing within social groups serves the formation (and maintenance) of affiliative bonds, especially between siblings, rather than pair bonds, but might additionally be explained by reciprocity, interchange, and harassment avoidance.     

Enhancing Bioinformatics and Genomics Courses: Building Capacity and Skills via Lab Meeting Activities

Reading, writing, publishing, and publicly presenting scientific works are vital for a young researcher's profile building and career development. Generally, the traditional educational curricula do not offer training possibilities to learn and practice how to prepare, write, and present scientific works. These are rather a part of lab meeting activities in research groups. The lack of such training is more critical in some developing countries because this adds to the rare opportunities to discuss and become involved in the exchanges on state of the art scientific literature. Here the authors relate their experience in introducing a weekly 1-day lab meeting in the framework of two previously organized 3-month courses on “Bioinformatics and Genome Analyses”. The main activities which are developed during these lab meetings include scientific literature follow up as well as preparing and presenting oral and written scientific reviews. These activities prove to be useful for a student's self-confidence building, for enhancing their active participation during the lectures and practical sessions, as well as for the positive impact on running the whole course program. Incorporation of such lab meeting activities in the course program significantly improves the capacity building of the participants, their analytical and critical reading of scientific literature, as well as communication skills. In this work it is shown how to proceed with the different steps involved in the implementation of lab meeting activities, and to recommend their regular institution in similar courses.
