Ecological conditions for Saxifraga hirculus in Central Europe: a better understanding for a good protection

Saxifraga hirculus is a postglacial relict in Central Europe, whose populations suffered a dramatic decrease in the 19th and 20th centuries. However, few researchers have been interested in its ecological requirements in Central Europe. This article synthesizes previous knowledge supplemented by original data from the last large population (Switzerland). S. hirculus is a weak competitor which needs precise ecological conditions. It grows on bryophyte carpets in neutral to slightly acid wetlands, with stable water table close to the soil surface (optimum between 8-14 cm) but does not stand long flooding. However, it requires a good oxygen supply, with roots 2-3 cm under the soil surface, generally not reached by water, with running, cold water through loose, fibric peat. Its optimal conditions are in spring fens, but it grows in other types of wetlands as well. However, overgrowing by shrubs, sedges or Sphagnum in natural successions may threaten the species with extinction, as did drainage and peat extraction previously. Now, its survival in Central Europe depends on an adequate management of the ecosystems. Moderate grazing (cattle or sheep) or mowing help to limit competition with taller Carex species. Re-introduction of disappeared populations or creation of new ones from cultivation in botanical garden is possible, but appropriate sites are rare. In some cases, substrate management could improve the conditions in somewhat inadequate situations. This management in four directions can be flexibly applied in different situations to progress to optimal conditions for the conservation of this valuable species

End-of-life care for gay, lesbian, bisexual and transgender people

There is little understanding in Australia of the special issues faced by gay, lesbian, bisexual and transgender people in end-of-life care and advance care planning. This exploratory study aimed to achieve an initial understanding of these issues to inform the development of a larger study involving gay, lesbian, bisexual and transgender service users. Consultations were carried out with 19 service providers and 6 gay, lesbian, bisexual and transgender community members in the Northern Rivers and metropolitan Sydney areas of New South Wales, Australia. Participants reported barriers to health care service access due to discrimination, inappropriate care and lack of knowledge among both consumers and health care workers of legal rights at the end of life. While advance care planning can assist with improving end-of-life care, respondents reported a number of obstacles. These included a lack of knowledge and absence of perceived need and the additional obstacle of social isolation, leading to difficulties identifying alternative decision-makers. The study highlighted the need for education for gay, lesbian, bisexual and transgender people and health and aged care providers on existing legal provisions to prevent discrimination in end-of-life care
