Data from: Carcass predictability but not domestic pet introduction affects functional response of scavenger assemblage in urbanised habitats
<ol> <li><span>Urbanisation alters species richness and composition, but studies of urbanisation effects on ecological functions have often quantified variation in functional traits and changes in functional diversity rather than measuring directly how ecological functions vary between rural and urban assemblages. </span></li> <li><span>Consuming dead animal matter and recycling its nutrients stabilizes and structures food webs and therefore represents a key component of ecosystem functioning. Introduction of free-ranging domestic pet animals adds additional scavenger species to urban habitats, and increased predictability of carcass resources produced by human activities characterizes urban habitats. </span></li> <li><span>Here, we investigate the effect of urbanisation on the composition of diurnal and nocturnal scavenger assemblages and on the ecological function of carcass removal by using a carcass placement experiment in Swiss urban and adjacent rural habitats. </span></li> <li><span>While diurnal and nocturnal scavenger assemblages changed considerably from rural to urban areas by comprising particularly more domestic cats in the latter, carrion consumption rate did not differ between the two habitats. Predictability of carcass occurrence increased carrion consumption rate in both, urban and rural habitats but mainly native scavengers and not introduced domestic pets responded to the repeated placements.</span></li> <li><span>These results suggest that urbanisation shapes scavenger assemblage compositions without affecting their ecological function. The mechanism is likely due to a behavioural change of native scavengers in response to the occurrence of domestic pets resulting in functional plasticity of urban scavenger assemblages. The functional plasticity might be facilitated by the increased carcass predictability and additional anthropogenic food resources in urban habitats exploited by nutritionally flexible native scavenger species.</span></li> </ol>

Data from: Functional role of the cerebellum in Parkinson's disease: a PET study
<p><span><b>Objectives:</b> To test for cerebellar involvement in motor and nonmotor impairments in Parkinson's disease (PD), and to determine patterns of metabolic correlations with supratentorial brain structures, we correlated clinical motor, cognitive and psychiatric scales with cerebellar metabolism.</span></p> <p><span><b>Methods: </b>We included 90 patients with PD. Motor, cognitive and psychiatric domains were assessed, and resting-state <sup>18</sup>FDG-PET metabolic imaging was performed. The motor, cognitive and psychiatric scores were entered separately in a principal component analysis. We looked for correlations between these three principal components and cerebellar metabolism. Furthermore, we extracted the mean glucose metabolism value for each significant cerebellar cluster and looked for patterns of cerebrum‑cerebellum metabolic correlations.</span></p> <p><span><b>Results:</b> Severity of impairment was correlated with increased metabolism in the anterior lobes and vermis (motor domain), and the right Crus I, Crus II, and declive (cognitive domain), and the right Crus I and Crus II (psychiatric domain). There were no results surviving multiple testing corrections regarding the psychiatric domain. Moreover, we found distributed and overlapping ‑ but not identical‑ patterns of metabolic correlations for motor and cognitive domains. Specific supratentorial structures (cortical structures, basal ganglia, and thalamus) were strongly correlated with each of the cerebellar clusters. </span></p> <p><span><b>Conclusions:</b> These results confirm the role of the cerebellum in nonmotor domains of Parkinson's disease, with differential but overlapping patterns of metabolic correlations suggesting the involvement of cerebello‑thalamo-striatal‑cortical loops.</span></p>
