Terricolous lichen communities in lowlands occur especially in open dry habitats. Such communities are often dominated by species of the genus Cladonia, which are very variable in morphology, reproduction strategies, and secondary metabolites. In this work, we investigated traits-environment relationships considering vegetation dynamics, substrate pH, disturbance, and climate. A total of 122 plots were surveyed in 41 acidic dry grasslands in the western Po Plain (Northern Italy). Relationships between Cladonia traits and environmental variables were investigated by means of a model-based Fourth Corner Analysis. Thallus morphology and metabolites responded to vegetation dynamics, substrate pH, disturbance, and climate, whereas reproduction strategies responded only to vegetation dynamics. Traits’ correlations with vegetation dynamics elucidate their colonization patterns in open dry habitats or suggest biotic interactions with bryophytes and vascular plants. In addition, correlations between metabolites and environmental factors support interpretations of their ecological roles. Our results also stress the importance of studying traits’ relationships with climatic factors as an alert towards lichen reactions to climate change.

AbstractReductionist thinking in neuroscience is manifest in the widespread use of animal models of neuropsychiatric disorders. Broader investigations of diverse behaviors in non-model organisms and longer-term study of the mechanisms of plasticity will yield fundamental insights into the neurobiological, developmental, genetic, and environmental factors contributing to the “massively multifactorial system networks” which go awry in mental disorders.

Abstract The global prevalence of obesity has been rising at an alarming rate, accompanied by an increase in both childhood and maternal obesity. The concept of metabolic programming is highly topical, and in this context, describes a predisposition of offspring of obese mothers to the development of obesity independent of environmental factors. Research published in this issue of Clinical Science conducted by Litzenburger and colleagues (Clin. Sci. (Lond.) (2020) 134, 921–939) have identified sex-dependent differences in metabolic programming and identify putative signaling pathways involved in the differential phenotype of adipose tissue between males and females. Delineating the distinction between metabolically healthy and unhealthy obesity is a topic of emerging interest, and the precise nature of adipocytes are key to pathogenesis, independent of adipose tissue volume.

The World Health Organization's (WHO's) 2001 International Classification of Functioning Disability and Health (ICF) has as one of its central tenets the full inclusion of persons with disabilities in society. It acknowledges the need for medical and rehabilitation intervention in its biopscychosocial framework. However, the WHO realizes that society must do its part to facilitate this full participation and empowerment. Persons with complex communication needs (PWCCN) often need augmentative and alternative communication (AAC) in order to express themselves. However, in order to access and successfully use AAC, PWCCN need access to the necessary AAC devices and services, as well as a willing society to interact with them as full contributing members of society. The factors outside of a person's specific physical and/or cognitive functional limitations are addressed in the ICF via the Personal and Environmental Factors. Personal Factors include the individual's personality traits, lifestyle, experiences, social/educational/professional background, race, gender, and age. Environmental Factors include community support systems, social service agencies, governments, social networks, and those persons that interact with the PWCCN. This article addresses the sociopolitical influences on PWCCN and their functioning from a human rights perspective. The necessary introspective role of speech-language pathologists in this process is explored.
