Building an eDNA surveillance toolkit for invasive rodents on islands: can we detect wild-type and gene drive Mus musculus?

BMC Biology, Год журнала: 2024, Номер 22(1)

Опубликована: Ноя. 15, 2024

Abstract Background Invasive management strategies range from preventing new invasive species incursions to eliminating established populations, with all requiring effective monitoring guide action. The use of DNA sampled the environment (eDNA) is one such tool that provides ability surveille and monitor target through passive sampling. Technology being developed eliminate includes genetic biocontrol in form gene drive. This approach would drive a trait population could be used or modify population. Once organism released into then changes density spread critical. Results In this paper, we Mus musculus as model for development an eDNA assay detects wild-type M. . We demonstrate successful where environmental samples detect relative Conclusions method both ( t CRISPR ) expands utility DNA. can immediately deployed wild across world. proof-of-concept construct monitored using samples.

Gene drives for invasive wasp control: Extinction is unlikely, with suppression dependent on dispersal and growth rates

Ecological Applications, Год журнала: 2023, Номер 33(7)

Опубликована: Авг. 24, 2023

Gene drives offer a potentially revolutionary method for pest control over large spatial extents. These genetic modifications spread deleterious variants through population and have been proposed as methods suppression or even eradication. We examined the influence of local dispersal, long-distance and/or human-mediated variation in growth on success gene drive invasive social wasps (Vespula vulgaris). Our simulations incorporated spatially realistic environment containing variable habitat quality New Zealand. Pest eradication was not observed, except extreme unrealistic scenarios constant, widespread, intense releases genetically modified individuals every year decades. Instead, regional persistence wild-type predicted. Simulations using homogeneous versus landscapes (incorporating uninhabitable areas dispersal barriers) showed little difference overall dynamics. Overall, impact wasp abundance observed first 15 years after introduction. After 25 years, populations were suppressed to levels <95% starting populations. Populations exhibited "chase dynamics" with cycles space, extinction occurring some while became abundant others. Increasing wasps' distance increased temporal variability occupied area suppression. Varying human-associated had effect intrinsic rates interacted cause higher mean substantially total amount landscape occupied. appear unlikely rapid widespread this probably other pests but could long-term cost-effective The predicted level would reduce predation pressure competitive interactions native species. However, will ethics likelihood control, especially given concerns that eventually be transported back their home range.

Gene Drives as Interventions into Nature: the Coproduction of Ontology and Morality in the Gene Drive Debate

NanoEthics, Год журнала: 2023, Номер 17(1)

Опубликована: Апрель 1, 2023

Abstract Gene drives are potentially ontologically and morally disruptive technologies. The potential to shape evolutionary processes eradicate (e.g. malaria-transmitting or invasive) populations raises ontological questions about evolution, nature, wilderness. transformative promises perils of gene also raise pressing ethical political concerns. aim this article is arrive at a better understanding the drive debate by analysing how moral assumptions coproduced in debate. Combining philosophical analysis with critical reading literature an ethnographic study two leading research groups, explores hypothesis that development characterized particular intervention-oriented mode coproduction. Based on results exploration, we highlight need for broadening perspective which empirical, moral, concerns addressed explicitly their interplay rather than (disciplinary) isolation from each other.

Novel organisms and the ethics of conservation: Divergent views on gene drives reflect divergent ideas about humans and nature

GAIA - Ecological Perspectives for Science and Society, Год журнала: 2023, Номер 33(1), С. 170 - 174

Опубликована: Май 1, 2023

What concepts of nature, humans, and their relationships underpin the debate about gene drives for conservation? To provide some answers to this question, eradication invasive rodents on islands is used as an example. While current debates mostly weigh potential benefits conservation against ecological risks, it worthwhile move beyond such a risk-benefit perspective. Ethical issues that are more specific are: significance “natural”, normative goals conservation, ideal living in harmony with nature.

Taking stock: Is gene drive research delivering on its principles?

Gates Open Research, Год журнала: 2024, Номер 8, С. 14 - 14

Опубликована: Фев. 22, 2024

Gene drive technology has been recognized for its potential to provide durable and cost-effective solutions previously intractable problems in public health, conservation, agriculture. In recognition of the rapid advances this field, 2016 U.S. National Academies Sciences, Engineering, Medicine issued a report making several recommendations aimed at researchers, funders, policymakers safe responsible research development gene technology. Subsequently, 2017 sixteen global organizations self-identifying as sponsors supporters became signatories committed ‘Principles Gene Drive Research’ which were inspired by report’s recommendations. Herein we reflect on progress relation ethical principles laid out Principles. Our analysis indicates high levels alignment with Principles field research. The manuscript also discusses Research Forum, had genesis publication Discussions between participants latest meeting Forum point work that lies ahead line Going forward community can productively focus on: i) safety efficacy criteria open release, ii) risk assessment frameworks methods, iii) more downstream technical, regulatory policy considerations evaluations implementation, iv) continued transparency developing mechanisms accountability, v) strengthening capacity locales release expected spread.
