Habitat-related birdsong divergence: a multi-level study on the influence of territory density and ambient noise in European blackbirds

Song plays an important role in avian communication and acoustic variation is important at both the individual and population level. Habitat-related variation between populations in particular can reflect adaptations to the environment accumulated over generations, but this may not always be the case. In this study, we test whether variation between individuals matches local conditions with respect to noise level and territory density to examine whether short-term flexibility could contribute to song divergence at the population level. We conducted a case study on an urban and forest population of the European blackbird and show divergence at the population level (i.e. across habitats) in blackbird song, anthropogenic noise level and territory density. Unlike in several other species, we found a lack of any correlation at the individual level (i.e. across individuals) between song features and ambient noise. This suggests species-specific causal explanations for noise-dependent song differentiation which are likely associated with variation in song-copying behaviour or feedback constraints related to variable singing styles. On the other hand, we found that at the level of individual territories, temporal features, but not spectral ones, are correlated to territory density and seasonality. This suggests that short-term individual variation can indeed contribute to habitat-dependent divergence at the population level. As this may undermine the potential role for song as a population marker, we conclude that more investigations on individual song flexibility are required for a better understanding of the impact of population-level song divergence on hybridisation and speciation

An integrated approach to neuroscience care: An innovative model to support the new integrated care system

Integrated care systems join up health and care services, so that people have the support they need, in the right place, at the right time. The aims include improving outcomes in healthcare, tackling inequalities in access and enhancing productivity and value for money. This is needed for neuroscience care as the traditional delivery of neuroscience care is inefficient, outdated and expensive, and can involve complex referral pathways and long waiting times. In preparation for the formation of the integrated care system (ICS), a novel innovative collaboration across multiple NHS trusts developed across North Central London in 2021. We developed a model where neuroscience specialists engage in collaborative care with clinicians outside the specialist hospital setting. Pivotal to the pathway is a multidisciplinary meeting, and collaborative working enables joint clinical reviews, diagnostics and medication initiation. This innovative collaboration has already significantly improved access, addressed inequalities due to borough variation and enhanced the delivery and quality of neuroscience care in our ICS. It is a translatable model that can be adapted to suit other regions in the UK. It fulfils many of the objectives of the integrated care system and these benefits are seen without the need for significantly more resource

Radiation-induced bowel injury: the impact of radiotherapy on survivorship after treatment for gynaecological cancers

The number of women surviving cancer who live with symptoms of bowel toxicity affecting their quality of life continues to rise. In this retrospective study, we sought to describe and analyse the presenting clinical features in our cohort, and evaluate possible predictors of severity and chronicity in women with radiation-induced bowel injury after treatment for cervical and endometrial cancers
