Conserved community structure and simultaneous divergence events in the fig wasps associated with Ficus benjamina in Australia and China

Localised patterns of species diversity can be influenced by many factors, including regional species pools, biogeographic features and interspecific interactions. Despite recognition of these issues, we still know surprisingly little about how invertebrate biodiversity is structured across geographic scales. In particular, there have been few studies of how insect communities vary geographically while using the same plant host. We compared the composition (species, genera) and functional structure (guilds) of the chalcid wasp communities associated with the widespread fig tree, Ficus benjamina, towards the northern (Hainan province, China) and southern (Queensland, Australia) edges of its natural range. Sequence data were generated for nuclear and mtDNA markers and used to delimit species, and Bayesian divergence analyses were used to test patterns of community cohesion through evolutionary time. Both communities host at least 14 fig wasp species, but no species are shared across continents. Community composition is similar at the genus level, with six genera shared although some differ in species diversity between China and Australia; a further three genera occur in only China or Australia. Community functional structure remains very similar in terms of numbers of species in each ecological guild despite community composition differing a little (genera) or a lot (species), depending on taxonomic level. Bayesian clustering analyses favour a single community divergence event across continents over multiple events for different ecological guilds. Molecular dating estimates of lineage splits between nearest inter-continental species pairs are broadly consistent with a scenario of synchronous community divergence from a shared "ancestral community". Fig wasp community structure and genus-level composition are largely conserved in a wide geographic comparison between China and Australia. Moreover, dating analyses suggest that the functional community structure has remained stable for long periods during historic range expansions. This suggests that ecological interactions between species may play a persistent role in shaping these communities, in contrast to findings in some comparable temperate systems

The psychological impacts of taking physiotherapy teaching online in 2020 : what did we learn?

Introduction. The rapid shift to online learning due to the COVID-19 pandemic presented challenges for physical therapy (PT) education worldwide. This article aims to explore the factors influencing the well-being of the PT faculty and department chairs involved in delivering PT programs during the initial stages of the COVID-19 pandemic. Review of Literature. The literature has focused on the pedagogical impacts of the rapid shift to online learning. Little is known about the social and psychological impacts of this rapid transition on the well-being of the faculty involved in implementing PT programs. Subjects. Physical therapy faculty and department chairs at 3 universities in metropolitan Sydney, Australia who taught into or led PT programs in 2020. Methods. Focus group methodology was used to explore the experiences of PT faculty and department chairs during the initial stages of the COVID pandemic. The focus groups were digitally recorded and transcribed verbatim and the transcripts analyzed thematically. Results: The main finding of this study was the extent of stress experienced by PT program faculty and chairs during this period. Both work-related institutional and faculty factors and non-work-related personal factors contributed to perceived high levels of stress. Overall, there was a feeling that the stressors had not improved over the duration of the pandemic and that this had left the faculty and chairs feeling more fatigued, less collegiate, and may have ongoing impacts on their mental health. Discussion: The pandemic created stresses for faculty and program chairs over and above the usual stress of faculty and college work. The reality of taking steps to reduce the stressors in the current climate is very difficult. Conclusion. Moving forward, it is vital to secure increased institutional support, including the support for creating realistic boundaries without the risk of penalty, to address the psychological health and well-being of PT faculty and chairs to enable high-quality education in the future

'Suddenly There Was Nothing’: foot and mouth, communal trauma and landscape photography

This paper examines the landscape photography that emerged during the Foot and Mouth epidemic in the UK in 2001. It builds upon Convery et al.’s proposal that the epidemic constituted a communally traumatic event in the worst affected areas, specifically Cumbria in North West England. This proposal can be seen as Alexander’s “cultural construction of trauma”: an act that specifically reframes a “disastrous” event as “traumatic”. However this process was aided by the landscape imagery that appeared in the intense press coverage of the epidemic, and by photographers working in the artistic or documentary sphere, such as John Darwell, Ian Geering and Nick May. This paper examines how landscape imagery can communicate the traumatic human experience of a changed lifescape, and how the broadcast of these images has contributed to the wider acknowledgement of Foot and Mouth as communal trauma. It argues that this imagery is actually essential to understanding the traumatic experience of a crisis which happened within, and to, the landscape
