Abstract

The thesis will show how Jennifer Dawson's fiction of the 1960s and '70s explores the effects of the overlapping dialects of the normalizing discourse, interlocking manifestations of constraint that consolidate themselves through internalization on a continuum that underpins, generates, perpetuates and constitutes perceptions of `the social. ' A Laingian reading of the scapegoating of perceived dissenters, to invalidate or ideally to pre-empt implied dissent and to confirm in their membership the members of `the group, ' will be applied to illuminate the response provoked by Dawson's protagonists, semantically discredited by a continuum of coercive structures that range from the psychiatric to the dynamic of individual relationships. A Foucauldian analysis of the transition of the maintenance of the status quo from identifiable applications of force to democratized formulations of normalizing power to an internalization of the panoptic principle will further contextualize the dilemmas and tensions of Dawson's protagonists, on whose experience Procrustean identities are systematically if subtly imposed. A Foucauldian perspective will be used to cast light on the feelings of deadlock addressed in the novels, where the tendency of power to incite identification makes a locus of authentic resistance elusive and hard to sustain. This perspective will also inform how Dawson's fiction dramatizes the futility of resistance that fails to engage at the level of form and which thus reinforces power's underlying paradigm, even on the sites of its ostensible subversion. The thesis will demonstrate how her novels increasingly reflect the Laingian concept of contextual intelligibility, revealing how the targets and transmission wires of the normalizing drive are fully enmeshed in power's dynamic structure. Foucault's emphasis on the interstitial will be applied to show how, in her fiction of the `70s, the mutual impact of individual lives is portrayed as not only constraining but also as potentially inspiring. Her protagonists move towards a conscious awareness of the need to forge and activate an interstitial perspective, symbolized initially by music, from which to transcend collusion with the normalizing drive. Only when `freedom' is understood to be not a destination but an attitude of mind do her protagonists emerge from the impasse of complicity and develop a receptiveness to genuine exchange and a view of themselves as more than merely acted upon but as potential definers and inhabitants of their experience.

Abstract

Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a "Green List of Species" (now the IUCN Green Status of Species). A draft Green Status framework for assessing species' progress toward recovery, published in 2018, proposed 2 separate but interlinked components: a standardized method (i.e., measurement against benchmarks of species' viability, functionality, and preimpact distribution) to determine current species recovery status (herein species recovery score) and application of that method to estimate past and potential future impacts of conservation based on 4 metrics (conservation legacy, conservation dependence, conservation gain, and recovery potential). We tested the framework with 181 species representing diverse taxa, life histories, biomes, and IUCN Red List categories (extinction risk). Based on the observed distribution of species' recovery scores, we propose the following species recovery categories: fully recovered, slightly depleted, moderately depleted, largely depleted, critically depleted, extinct in the wild, and indeterminate. Fifty-nine percent of tested species were considered largely or critically depleted. Although there was a negative relationship between extinction risk and species recovery score, variation was considerable. Some species in lower risk categories were assessed as farther from recovery than those at higher risk. This emphasizes that species recovery is conceptually different from extinction risk and reinforces the utility of the IUCN Green Status of Species to more fully understand species conservation status. Although extinction risk did not predict conservation legacy, conservation dependence, or conservation gain, it was positively correlated with recovery potential. Only 1.7% of tested species were categorized as zero across all 4 of these conservation impact metrics, indicating that conservation has, or will, play a role in improving or maintaining species status for the vast majority of these species. Based on our results, we devised an updated assessment framework that introduces the option of using a dynamic baseline to assess future impacts of conservation over the short term to avoid misleading results which were generated in a small number of cases, and redefines short term as 10 years to better align with conservation planning. These changes are reflected in the IUCN Green Status of Species Standard.

6. Going native, going local: revegetating eroded soils on the Falkland Islands using native seeds and farmland waste

Abstract

Remote island ecosystems are vulnerable to human disturbance and habitat destruction, yet they often have limited capacity to revegetate degraded habitats, especially with native species. To revegetate degraded island habitats, practitioners often rely on importing non-native species, thereby increasing the number of introduced species on islands. In this study, we investigated the effectiveness of sowing wild collected native seeds and locally sourced treatments for revegetating different eroded soil types (clay, peat, and sand) across the Falkland Islands. A seed mixture of 15 native species was sown with different supportive treatments (sheep dung, sheep dags [woolly off-cuts], and geotextile matting [coir]) and their combinations. After 1 year, native seeds provided up to 70% plant cover and accrued 1.98 kg/m2 in biomass. Three key native species Elymus magellanicus, Poa flabellata, and Poa alopecurus occurred in 64, 50, and 50% of all sown plots. However, supportive treatments equally facilitated the colonization and establishment of non-native species. At the same time, there was no difference in native plant cover and biomass across different treatments or soil types, although in the absence of supportive treatments there was little to no revegetation. Thus, locally sourced treatments (i.e. sheep dung and dags) may provide an equally effective but low-cost alternative to imported treatments (i.e. geotextiles). We further discuss challenges of integrating revegetation using native seeds and livestock grazing on the Falkland Islands. Our study demonstrates that native species and local treatments can provide a rapid approach to revegetating degraded island habitats. This is the peer reviewed version of an article, which has been published in final form at [https://doi.org/10.1111/rec.12552].

Abstract

Resurrecting extinct species is a fascinating and challenging idea for scientists and the general public. Whereas some theoretical progress has been made for animals, the resurrection of extinct plants (de-extinction sensu lato) is a relatively recently discussed topic. In this context, the term 'de-extinction' is used sensu lato to refer to the resurrection of 'extinct in the wild' species from seeds or tissues preserved in herbaria, as we acknowledge the current impossibility of knowing a priori whether a herbarium seed is alive and can germinate. In plants, this could be achieved by germinating or in vitro tissue-culturing old diaspores such as seeds or spores available in herbarium specimens. This paper reports the first list of plant de-extinction candidates based on the actual availability of seeds in herbarium specimens of globally extinct plants. We reviewed globally extinct seed plants using online resources and additional literature on national red lists, resulting in a list of 361 extinct taxa. We then proposed a method of prioritizing candidates for seed-plant de-extinction from diaspores found in herbarium specimens and complemented this with a phylogenetic approach to identify species that may maximize evolutionarily distinct features. Finally, combining data on seed storage behaviour and longevity, as well as specimen age in the novel 'best de-extinction candidate' score (DEXSCO), we identified 556 herbarium specimens belonging to 161 extinct species with available seeds. We expect that this list of de-extinction candidates and the novel approach to rank them will boost research efforts towards the first-ever plant de-extinction.
