- The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

Positive associations among rare species and their persistence in ecological assemblages
- 2020

In: Nature Ecology & Evolution. - : Nature Publishing Group. - 2397-334X. ; 4:1, s. 40-45

Journal article (peer-reviewed)abstract
- According to the competitive exclusion principle, species with low competitive abilities should be excluded by more efficient competitors; yet, they generally remain as rare species. Here, we describe the positive and negative spatial association networks of 326 disparate assemblages, showing a general organization pattern that simultaneously supports the primacy of competition and the persistence of rare species. Abundant species monopolize negative associations in about 90% of the assemblages. On the other hand, rare species are mostly involved in positive associations, forming small network modules. Simulations suggest that positive interactions among rare species and microhabitat preferences are the most probable mechanisms underpinning this pattern and rare species persistence. The consistent results across taxa and geography suggest a general explanation for the maintenance of biodiversity in competitive environments. Analysing spatial association networks among >300 terrestrial and aquatic assemblages, the authors find that the majority of negative associations involve abundant species. In contrast, rare species form mostly positive associations, potentially explaining their persistence in natural communities.

Molecular andmorphological circumscription of Brachytheciumcoruscum as a separate taxon from Brachytheciumalbicans (Brachytheciaceae, Bryophyta)
- 2014
-
In: Phytotaxa. - : Magnolia Press. - 1179-3155 .- 1179-3163. ; 158, s. 182-194

Journal article (peer-reviewed)abstract
- Nuclear ITS, and chloroplast rpl16 and trnG sequences, together with morphological data, were used to circumscribe some problematic taxa within the complex around the pleurocarpous moss Brachythecium albicans. Brachythecium coruscum is consistently different from B. albicans, and its description is here amended. On the contrary, segregation of Brachythecium dumetorum from B. albicans is unsupported both according to molecular and morphological data, and the two taxa are therefore considered to be synonyms.

Clinical characteristics, impairment, and psychiatric morbidity in 102 youth with misophonia
- 2022
-
In: Journal of Affective Disorders. - : Elsevier BV. - 0165-0327. ; 324, s. 395-402
-
Journal article (peer-reviewed)abstract
- BackgroundThere is little information on the clinical presentation, functional impact, and psychiatric characteristics of misophonia in youth, an increasingly recognized syndrome characterized by high emotional reactivity to certain sounds and associated visual stimuli.MethodOne-hundred-two youth (8–17 years-old) with misophonia and their parents were recruited and compared with 94 youth with anxiety disorders. Participants completed validated assessments of misophonia severity, quality of life, as well as psychiatric symptoms and diagnoses.ResultsThe most common misophonia triggers included eating (96 %), breathing (84 %), throat sounds (66 %), and tapping (54 %). Annoyance/irritation, verbal aggression, avoidance behavior, and family impact were nearly universal. Misophonia severity was associated with internalizing symptoms, child-reported externalizing behaviors, and poorer quality of life. High rates of comorbidity with internalizing and neurodevelopmental disorders were found. Quality of life and externalizing behaviors were not significantly different between misophonia and anxiety samples; internalizing symptoms and autism characteristics were significantly higher among youth with anxiety disorders.LimitationsThis self-selected sample was characterized by limited multicultural diversity.ConclusionsThis study presents misophonia as a highly impairing psychiatric syndrome. Future interdisciplinary work should clarify the mechanisms of misophonia, establish evidence-based treatments, and extend these findings to randomly sampled and more culturally diverse populations.

Alterations in attentional processing in youth with misophonia: A phenotypical cross-comparison with anxiety patients
- 2024
-
In: Journal of Affective Disorders. - 0165-0327. ; 347, s. 429-436
-
Journal article (peer-reviewed)abstract
- BackgroundMisophonia is a complex condition characterized by extreme emotional distress in response to specific sounds or specific visual stimuli. Despite a growing body of clinical and neuroscientific literature, the etiology of this condition remains unclear. Hyperarousal, that is, a state of heightened alertness and disinhibition, as a core feature of misophonia is supported by behavioral and neuroimaging literature and might represent a viable clinical target for the development of both behavioral and pharmacological interventions. The aim of this study was to investigate how hyperarousal might be linked to neurocognitive processes associated with vigilance and stimulus discrimination in youth with misophonia.MethodsWe compared 72 children and adolescents with misophonia (13.74 ± 2.44 years) (64 % female) and 89 children and adolescents with anxiety (12.35 ± 2.57 years) (58.4 % female) on behavioral and signal detection performance of the immediate memory task (IMT). Anxiety patients were used as a clinical control group to distinguish attentional processes specific for misophonia.ResultsBoth groups demonstrated similar behavioral performance, including response rate and reaction time. However, misophonia was associated with elevated stimulus discrimination (d prime), which in turn was positively correlated with the severity of misophonia trigger reports.ConclusionsOur findings are in line with previous cognitive and neuroimaging studies, and support an arousal-based model of misophonia, where individuals with misophonia experience a state of heightened vigilance, being more aware of stimuli in the environment. Our findings provide a neurocognitive basis for future study of neurochemical imaging that might further progress towards clinical targets.

Family Accommodation in Children and Adolescents with Misophonia
-
In: Behavior Therapy. - 1878-1888.
-
Journal article (peer-reviewed)abstract
- Family accommodation (e.g., reassurance, modifying routines, assisting avoidance) has not been explored among youth with misophonia but may have important clinical and intervention implications. We examined family accommodation in 102 children and adolescents with interview-confirmed misophonia and compared its frequency and content to family accommodation in 95 children and adolescents with anxiety disorders. Findings showed that family accommodation was ubiquitous in pediatric misophonia and may be even more frequent than in youth with anxiety disorders. Assisting the child, participating in misophonia-related behaviors, and modifying family routines were endorsed by more than 70% of parents of children with misophonia. Further, compared to parents of children with anxiety disorders, parents of children with misophonia more frequently reported child distress and anger when they did not accommodate. Family accommodation was a moderate to strong predictor of misophonia severity even when accounting for co-occurring internalizing and externalizing symptoms and sociodemographic factors. This first study of family accommodation in pediatric misophonia suggests accommodation may be an important clinical feature oand a potential candidate to target in interventions.
