Ítem A significantly enhanced role for plant genetic resource centres(European Cooperative Programme for Plant Genetic Resources, 2025-05-09) Maxted, N.; Adam-Blondon, A.-F.; Aguilar, C.H.; Barata, A.M.; Bartha, B.,; Bocci, R.; De Paola, D.; Fitzgerald, H.; Fresta, L.; Fusani, P.; Giuliano, G.; Guzzon, F.; Holzherr, P.; Holubec, V.; Iriondo, J.M.; et al.Plant genetic resources (PGR) serve as the cornerstone for global varietal enhancement and food security. However, these resources face significant threats, including diversity erosion and extinction, are often inadequately conserved, and frequently remain inaccessible for practical use. Traditionally, PGR have been primarily conserved through population seed samples stored ex situ in genebanks. In contrast, complementary in situ techniques – whether involving crop wild relatives (CWR) in genetic reserves or crop landraces (LR) on-farm – have largely remained experimental. The demand from breeders for a broader diversity is driving a more integrated approach that combines ex situ and in situ methods. This paper posits that such an integrated strategy would be mutually advantageous for PGR, biodiversity, and farmer-based conservation communities. As a foundation for future PGR science, we propose the three ‘Principles of PGR Conservation and Use Congruence’ and outline the practical processes involved in in situ and on-farm conservation. We also review the challenges associated with integrating ex situ and in situ conservation, specifically addressing how collaborative resource management can be established, how potential resource users can access in situ and on-farm conserved PGR, how to promote user access to in situ conserved populations, and the progress made thus far in integrating in situ and ex situ efforts. While it is acknowledged that full integration may be unrealistic without adequate resources for Genetic Resource Centres and the rectification of skill gaps, the potential to significantly enhance the long-term, sustainable conservation of PGR diversity holds profound existential benefits for humanity in the 21st century.Ítem Are lianas more drought-tolerant than trees?

A comparative study of 18 countries(Journalism Studies, 2011) Hanitzsch, Thomas; Folker, Hanusch; Mellado, Claudia; Anikina, Maria; Berganza, Rosa; et al.This article reports key findings from a comparative survey of the role perceptions, epistemological orientations and ethical views of 1800 journalists from 18 countries. The results show that detachment, non-involvement, providing political information and monitoring the government are considered essential journalistic functions around the globe. Impartiality, the reliability and factualness of information, as well as adherence to universal ethical principles are also valued worldwide, though their perceived importance varies across countries.Ítem Pervasive and strong effects of plants on soil chemistry: A meta-analysis of individual plant ‘zinke’ effects(Proceedings of the Royal Society B: Biological Sciences, 2015) Waring, Bonnie G.; et al.Ítem Sapling performance along resource gradients drives tree species distributions within and across tropical forests(Ecology, 2014) Sterck, Frank; et al.Ítem Soil carbon stocks across tropical forests of Panama regulated by base cation effects on fine roots(Biogeochemistry, 2018) Cusack, Daniela F.; et al.
