Swallow nest box, fence and pond at Clifford E. Lee Nature Sanctuary
No full textWinter landscape looking west from Sanctuary Road across the north pond at the Clifford E. Lee Nature Sanctuary. In the foreground is a rail fence and a nest box attached to fence post. Behind the fence are cattails along the edge of the pond. In the summer of 2025, tree swallows nested in the nest box
Data and R scripts supporting "Social and structural traits influence species gains while resources influence species losses in a native grassland".
No full textMultiple factors influence temporal species turnover, including resource requirements and species traits. The standard model in plant ecology is that adding soil nutrients will result in taller communities, reducing understory light levels and leading to species loss via size asymmetric competition. However, underlying this model is the notion that competitive dynamics are outcomes of individual species characteristics rather than an emergent trait of the suite of species involved in the interactions. Thus, whether plant social context (identities and interactions of neighbours) impacts competitive outcomes is unclear and potentially overlooked. Using data from a three-year field study manipulating light and soil resources, we asked how resource manipulations, community diversity, or structural (physiological) and social (interactions with neighbours) traits influenced species turnover. We created co-occurrence networks to develop novel metrics that capture the prevalence of positive and negative associations for each of 24 species in a native grassland community. We then estimated temporal beta diversity to partition species turnover into gains, losses and turnover, testing whether these compositional changes were impacted by resource manipulations or communities’ structural or social traits. We found evidence that resources, structural traits, and social traits all impacted aspects of community assembly. Nutrient addition but not reduced light increased species losses, and communities with either high or low specific leaf area (SLA) and root tissue density (RTD) community-weighted mean (CWM) trait values gained more species. Communities consisting of species forming numerous positive species co-occurrences gained fewer species throughout the study than communities of species forming fewer positive co-occurrences. Thus, a species’ tendency to form positive co-occurrences has a functional consequence for community-level compositional stability. Resource addition increased species losses independently of CWM height, suggesting it was not size-asymmetric competition for light that resulted in species loss in our study. Together, these results challenge the notion that nutrient-driven species loss is primarily mediated by size-asymmetric competition, highlighting the role of species’ social interactions in governing community change
What is known about real-life autistic doctors? A scoping review of the literature
No full textElectronic supplementary material for C. Vaughan Bowen’s Master’s thesis.
Very little is known about real-life autistic doctors. The purpose of this study was to collect and examine the full extent of the literature to address the question “What has been written about real-life autistic physicians?” and to answer secondary questions of “What is the prevalence of autistic physicians?”, “What type of medicine do they practice?”, and “What are their strengths, challenges and needs?” A methodologically broad and rigorous search of documents posted or published from August 1994 to December 2024 yielded a very heterogenous collection of documents. Four categories of documents were published, with a surge starting in 2019: personal stories and disclosures (n = 32), commentaries and opinions (n = 72), internet forum threads (n = 29), and research studies (n = 9). Autistic physicians make up 1%, or more, of the medical workforce. Most are general practitioners (31%), then psychiatrists (18%), then anaesthetists (11%). They are good physicians with hyperfocus, attention to detail, excellent recall, creative problem-solving ability, enhanced pattern recognition, strong work ethic, self motivation and empathy. They also have challenges. They are misunderstood and misunderstand others. They need to make personal adjustments and to ask others for accommodations. Many are still undiagnosed but those, who recognise their autism, prefer to see neurodiversity as a difference rather than a deficit. They need support to flourish in practice. Despite increasing awareness, however, prejudice, discrimination and stigmatisation are still barriers for autistic physicians. These can have far reaching repercussions to careers and personal well-being, sometimes with significant mental health consequences
Entrance sign for the Clifford E. Lee Nature Sanctuary in winter
No full textThis sign, made of carved wood and metal post shows the name of the sanctuary and a yellow-headed blackbird, the symbol of the Clifford E. Lee Nature Sanctuary. During the summer months,
yellow-headed blackbirds can often be spotted on the cattails along the trail at the sanctuary
Rose hips dried on the bush
