Taxonomy 2.0: computer-aided identification tools to assist Antarctic biologists in the field and in the laboratory
2020
Species inventories are essential to the implementation of conservation policies to mitigate biodiversity loss and maintain ecosystem services and their value to the society. This is particularly topical with respect to climate change and direct anthropogenic effects on Antarctic biodiversity, with the identification of the most at-risk taxa and geographical areas becoming a priority. Identification tools are often neglected and considered helpful only for taxonomists. However, the development of new online information technologies and computer-aided identification tools provides an opportunity to promote them to a wider audience, especially considering the emerging generation of scientists…

Retention forestry and biodiversity conservation: a parallel with agroforestry
2013
In forested landscapes two general management systems – retention forestry and agroforestry – have been proposed as potentially efficient components of landscape approaches to ease the conflict between biodiversity objectives and human needs. In two recent reviews, Gustafsson et al. (2012) and Lindenmayer et al. (2012) provide a global overview of current knowledge about the practice and ecological roles of retention forestry. A few years ago, Bhagwat et al. (2008) produced a similar review addressing the role of agroforestry in biodiversity conservation. Here we draw a parallel between research on the ecological effects of retention forestry and agroforestry. We argue that conservation sci…
La enseñanza monumentalista y utilitarista de las causas de la biodiversidad y de las estrategias para su conservación: un estudio sobre la transposi…
2015
Este trabajo estudia la presencia y complejidad en el tratamiento de las causas de la biodiversidad y de las razones para su conservación que realizan manuales escolares de la Educación Secundaria de España. Para ello, se determinó el ámbito conceptual y axiológico que define la comunidad de expertos, se examinó el tratamiento propuesto en el currículo español y se analizaron 50 manuales escolares (27 de la Educación Secundaria Obligatoria –ESO – y 30 del Bachillerato). Los resultados mostraron que el proceso de transposición didáctica vuelve monumentalista la enseñanza de la biodiversidad, ya que olvida las razones de su existencia, y se enriquece de connotaciones biologicistas y utilitari…
The community conserved landscape of the Borana Oromo, Ethiopia
2011
Purpose - This paper seeks to describe an attempt to assess at the local level the progress that has been internationally achieved in recognition of community and indigenous rights, and of indigenous and community conserved areas. An action-research exercise was implemented in Ethiopia with a mobile indigenous people of evaluating customary as well as government-led governance of the environment, with the objective of strengthening the capacity of the Borana-Oromo to conserve their landscape. Design/methodology/approach - This paper is based on collaborative research implemented by the authors in 2002 while SOS Sahel Ethiopia was introducing collaborative forest management, and on a 2007 ac…
Vitality and growth of the threatened lichen Lobaria pulmonaria (L.) Hoffm. in response to logging and implications for its conservation in mediterra…
2020
Forest logging can be detrimental for non-vascular epiphytes, determining the loss of key components for ecosystem functioning. Legal logging in a Mediterranean mixed oak forest (Tuscany, Central Italy) in 2016 heavily impacted sensitive non-vascular epiphytes, including a large population of the threatened forest lichen Lobaria pulmonaria (L.) Hoffm. This event offered the background for this experiment, where the potential effects of logging in oak forests are simulated by means of L. pulmonaria micro-transplants (thallus fragments <
Management diversity begets biodiversity in production forest landscapes
2022
How to manage forest for biodiversity conservation is an ongoing debate. We argue that maximizing biodiversity in managed forest landscapes requires a diversity of forest management regimes in space and time. This will generate high levels of habitat heterogeneity at a landscape scale, which in turn will support various groups of forest species. Based on concepts from landscape ecology, we formulate five hypotheses on how management diversity, i.e. combining various management approaches can benefit overall biodiversity across a production forest landscape. First, management diversity will increase habitat diversity and, therefore, beta diversity (the habitat diversity hypothesis). Second, …
Red Listing plants under full national responsibility: Extinction risk and threats in the vascular flora endemic to Italy
2018
Abstract Taxa endemic to a country are key elements for setting national conservation priorities and for driving conservation strategies, since their persistence is entirely dependent on national policy. We applied the IUCN Red List categories to all Italian endemic vascular plants (1340 taxa) to assess their current risk of extinction and to highlight their major threats. Our results revealed that six taxa are already extinct and that 22.4% (300 taxa) are threatened with extinction, while 18.4% (247; especially belonging to apomictic groups) have been categorized as Data Deficient. Italian endemic vascular plants are primarily threatened by natural habitat modification due to agriculture, …
Conservation status of the Italian flora under the 92/43/EEC ‘Habitats’ Directive
2021
The results of the 4th National Report for the Italian flora under the 92/43/EEC ‘Habitats’ Directive are presented. The outcomes showed a general negative conservation status for plant species, with the worst situation being in the Mediterranean bioregion. At the National level, significant monitoring and conservation activities are required.
