A new species of Aquilegia (Ranunculaceae) from Sardinia (Italy)

The new species Aquilegia cremnophila (Ranunculaceae) from the Italian island of Sardinia is here described and illustrated. It occurs in shady rocky crevices, near the upper parts of Mt. Corrasi (Supramontes Region), where it is a member of chasmophilous communities. This species is morphologically, phenologically, ecologically and genetically well differentiated from the other Sardinian taxa, showing some relationships mainly with A. nugorensis, an endemic species of Central-Eastern Sardinia. Its conservation status is examined. A key of all taxa present in Sardinia is also provided

Spatial genetic structure of Aquilegia taxa endemic to the island of Sardinia

Background and Aims The Mediterranean Basin is one of the most important regions for the Earth’s plant biodiversity; however, the scarcity of studies on fine scale patterns of genetic variation in this region is striking. Here, an assessment is made of the spatial genetic structure of all known locations of the three Sardinian endemic species of Aquilegia in order to determine the relative roles of gene flow and genetic drift as underlying evolutionary forces canalizing the divergence of Sardinian Aquilegia taxa, and to see if the spatial genetic structure found fits the current taxonomic differentiation of these taxa. † Methods DNA from 89 individuals from all known locations of Aquilegia across Sardinia was analysed by means of amplified fragment length polymorphism (AFLP) markers. Both principal co-ordinates analysis (PCoA) and Bayesian clustering analyses were used to determine the spatial genetic structure irrespective of any taxonomic affiliation. Historical effects of gene flow and genetic drift were assessed by checking for the existence of isolation-by-distance patterns. † Key Results STRUCTURE and PCoA analyses revealed a pattern of genetic variation geographically structured into four spatial genetic groups. No migration–drift equilibrium was detected for Aquilegia in Sardinia, when analysed either as a whole or in individual groups. The scenario approached a Case III pattern sensu Hutchinson and Templeton, which is associated with extreme isolation conditions where genetic drift has historically played a dominant role over gene flow. †Conclusions The pattern of genetic variation of Sardinian taxa of Aquilegia indicates that genetic drift has been historically more influential than gene flow on population structure of Sardinian species of Aquilegia. Limited seed dispersal and divergent selection imposed by habitat conditions have been probably the main causes reinforcing post-Pleistocene geographical isolation of Aquilegia populations. The spatial genetic structure found here is not fully compatible with current taxonomic affiliations of Sardinian Aquilegia taxa. This is probably a consequence of the uncoupling between morphological and genetic patterns of differentiation frequently found in recently radiated taxa

Disability Management

none1noSummary Diversity management manifests in a set of transversal business practices – under the “umbrella” of the corporate social responsibility policies – that affect the corporate culture, the strategy, the financial and control management system, the operational activities, as well as the system of relations with the stakeholders and the company reporting (Angeloni 2013; D’Amato 2009; Metallo et al. 2009; Migliaccio 2016). The growing attention paid by policy makers, businesses, and institutions to diversity management is attributable to the increased complexity of society, characterized by a multiplicity of social, cultural, and individual subjectivities tied to gender, age, ethnic origins, disability, sexual orientation, personality characteristics, cognitive styles, level of education, background, etc. In such a context disability management is conceived as a proactive strategy aimed at identifying and solving the factors that prevent people with any type of disability from accessing work (Geisen and Harder 2011). While diversity management consists in practices that an organization implements to create an inclusive climate and an organizational culture (Oberfield 2014), aimed to allow workers attitudes and capabilities flourish and ensure growth and success of their personal and professional paths, disability management is not only limited to a process or to a set of procedures (O’Brien 2013; Sabharwal 2014), but it represents a professional activity which considers all the relational aspects (personal contacts and interactions) that contribute to the success of disability management. Currently disability strategies are often implemented as a reaction to the problems of a single person or an organization, while empirical studies suggest to consider such problems in advance through appropriate policies and procedures for overcoming and preventing them (Geisen and Harder 2011). Namely, workplace disability management concerns all cases of disability from personal and congenital disabilities tothose acquired during the working period (ranging from accidents to chronic-degenerative diseases). In this sense, disability management is conceived as a proactive strategy oriented to identify and remove all the factors that prevent people, with any type of disability, from accessing to developing a professional path (Bruyére and Filiberto 2013; Rahim et al. 2017). This conception differs from a more restrictive one according to which disability management coincides with the return to work, of disable people who are already working.https://link.springer.com/referencework/10.1007/978-3-030-02006-4 Book Springer Series: CSR, Sustainabiliy, Ethics & Governance.
