Student-Led Workshop on Disability Advocacy

ABSTRACT

Medical students can be powerful advocates for and in partnership with the disability community, yet opportunities for targeted advocacy training are sparse. In February 2023, a medical student-led workshop on disability advocacy for trainees took place at the Association of Academic Physiatrists' Annual Conference. The aims of this session were for trainees to (1) identify existing gaps in disability education at their institution and in policy around disability-related issues; (2) improve perceived ability to engage in disability-related education and policy-based advocacy; and (3) apply an intersectional lens to identify opportunities for intersectionality in disability advocacy. Pre- and post-session responses were anonymously submitted via Qualtrics. Of 31 pre-survey respondents, 18 responded to the post-survey, and 12 were identified as having matching unique identifiers. After the workshop, participants overall were more likely to report being very/somewhat confident about their ability to identify gaps in disability education at their institution (75.0% vs 100.0%, p = 0.011), policy around disability-related issues (41.7% vs 100.0%, p < 0.006), and opportunities for intersectionality in disability advocacy (33.3% vs 91.7%, p < 0.015). Participants were more likely to report being very/somewhat confident in engaging in education-based advocacy (58.3% vs 100.0%, p = 0.006), policy-based advocacy (16.7% vs 91.7%, p < 0.002) and intersectional disability advocacy (41.7% vs 91.7%, p < 0.006). All attendees strongly/somewhat agreed with the statements "I hope that this session will continue in future years" and "I think that other trainees would benefit from a similar course." This session was shown to effectively meet the intended goals of the program.

Minimal impacts of invasive Scaevola taccada on Scaevola plumieri via pollinator competition in Puerto Rico

Introduction

Scaevola taccada and Scaevola plumieri co-occur on shorelines of the Caribbean. Scaevola taccada is introduced in this habitat and directly competes with native dune vegetation, including S. plumieri, a species listed as locally endangered and threatened in Caribbean locations. This study addresses whether the invasive S. taccada also impacts the native S. plumieri indirectly by competing for pollinators and represents the first comparative study of insect visitation between these species.

Methods

Insect visitation rates were measured at sites where species co-occur and where only the native occurs. Where species cooccur, insect visitors were captured, identified and analyzed for the pollen they carry. Pollen found on open-pollinated flowers was analyzed to assess pollen movement between the two species. We also compared floral nectar from each species by measuring volume, sugar content, and presence and proportions of amine group containing constituents (AGCCs).

Results

Our results demonstrate that both species share insect visitors providing the context for possible pollinator competition, yet significant differences in visitation frequency were not found. We found evidence of asymmetrical heterospecific pollen deposition in the native species, suggesting a possible reproductive impact. Insect visitation rates for the native were not significantly different between invaded and uninvaded sites, suggesting that the invasive S. taccada does not limit pollinator visits to S. plumieri. Comparisons of nectar rewards from the invasive and the native reveal similar volumes and sugar concentrations, but significant differences in some amine group containing constituents that may enhance pollinator attraction.

Conclusion

Our analysis finds no evidence for pollination competition and therefore S. taccada's main impacts on S. plumieri are through competitive displacement and possibly through reproductive impacts as a consequence of heterospecific pollen deposition.
