Analysis of the influece of ungulates on the regeneration of Dinaric fir-beech forests in the research site Trnovec in the Kočevje forest managementregion
Kristjan Jarni, Dušan Robič, Andrej Bončina, 2004

Povzetek: In the period 1970-2000, 152 fenced-in areas were built in the Kočevje Forest Management Region with an aim to protect tree seedlings and saplings from ungulatesć activity and to monitor the influence of roe and red deer on natural regeneration. The average surface area of fenced areas is 0.71 ha. Using the pair comparison technique (fenced vs. unfenced areas), the structureand the composition of the natural regeneration of tree species as well as complete shrub and herb vegetation were analysed in the research site Trnovec. Furthermore, the vegetation was investigated using the Braun-Blanquetmethod. The research results show significant differences between fenced and unfenced areas, both in tree species composition and in theheight structure of the sapling community. In fenced areas the total numberof saplings taller than 50 cm is higher and an increase is also evident in the number of saplings of silver fir Abies alba, sycamore Acer pseudoplatanus, elm Ulmus glabra and other minor tree species. There are also significant differences in species composition and in the abundance of plant species in the herb layer. The results show that natural regeneration of Dinaric fir-beech forests is successful, provided the influence of ungulates is excluded.

Blind spots in global soil biodiversity and ecosystem function research
Tine Grebenc, Manuel Delgado-Baquerizo, Fernando T. Maestre, Matthias C. Rillig, Léa Beaumelle, Simone Cesarz, Nathaly Guerrero-Ramírez, Antonis Chatzinotas, Johannes Sikorski, Anna Heintz-Buschart, Carlos A. Guerra, 2020

Povzetek: Soils harbor a substantial fraction of the world's biodiversity, contributing to many crucial ecosystem functions. It is thus essential to identify general macroecological patterns related to the distribution and functioning of soil organisms to support their conservation and consideration by governance. These macroecological analyses need to represent the diversity of environmental conditions that can be found worldwide. Here we identify and characterize existing environmental gaps in soil taxa and ecosystem functioning data across soil macroecological studies and 17,186 sampling sites across the globe. These data gaps include important spatial, environmental, taxonomic, and functional gaps, and an almost complete absence of temporally explicit data. We also identify the limitations of soil macroecological studies to explore general patterns in soil biodiversity-ecosystem functioning relationships, with only 0.3% of all sampling sites having both information about biodiversity and function, although with different taxonomic groups and functions at each site. Based on this information, we provide clear priorities to support and expand soil macroecological research.

Ethical dilemmas when using citizen science for early detection of invasive tree pests and diseases
Erin Bullas-Appleton, Mariella Marzano, Michael J.O. Pocock, Alison Dyke, Maarten De Groot, Craig Shuttleworth, Rehema White, 2020

Povzetek: The early detection of tree health pests and disease is an important component of biosecurity to protect the aesthetic, recreational and economic importance of trees, woodlands and forestry. Citizen science is valuable in supporting the early detection of tree pests and diseases. Different stakeholders (government, business, society and individual) will vary in their opinion of the balance between costs and benefits of early detection and consequent management, partly because many costs are local whereas benefits are felt at larger scales. This can create clashes in motivations of those involved in citizen science, thus leading to ethical dilemmas about what is good and responsible conduct for the use of citizen science. We draw on our experience of tree health citizen science to exemplify five dilemmas. These dilemmas arise because: the consequences of detection may locally be severe (e.g. the destruction of trees); knowledge of these impacts could lead to refusal to make citizen science reports; citizen science reports can be made freely, but can be costly to respond to; participants may expect solutions even if these are not possible; and early detection is (by definition) a rare event. Effective engagement and dialogue across stakeholders, including public stakeholders, is important to properly address these issues. This is vital to ensure the public%s long-term support for and trust in the use of citizen science for the early detection of tree pests and diseases.

Development of an international Core Outcome Set (COS) for best care for the dying person : study protocol
Sofia C. Zambrano, Dagny Renata Faksvåg Haugen, Agnes van der Heide, Vilma A. Tripodoro, John Ellershaw, Carl-Johan Fürst, Raymond Voltz, Stephen Mason, María L. Daud, Gustavo De Simone, Urška Lunder, Hana Kodba Čeh, Miša Bakan, 2020

Povzetek: Background: In contrast to typical measures employed to assess outcomes in healthcare such as mortality or recovery rates, it is difficult to define which specific outcomes of care are the most important in caring for dying individuals. Despite a variety of tools employed to assess different dimensions of palliative care, there is no consensus on a set of core outcomes to be measured in the last days of life. In order to optimise decision making in clinical practice and comparability of interventional studies, we aim to identify and propose a set of core outcomes for the care of the dying person. Methods: Following the COMET initiative approach, the proposed study will proceed through four stages to develop a set of core outcomes: In stage 1, a systematic review of the literature will identify outcomes measured in existing peer reviewed literature, as well as outcomes derived through qualitative studies. Grey literature, will also be included. Stage 2 will allow for the identification and determination of patient and proxy defined outcomes of care at the end of life via quantitative and qualitative methods at an international level. In stage 3, from a list of salient outcomes identified through stages 1 and 2, international experts, family members, patients, and patient advocates will be asked to score the importance of the preselected outcomes through a Delphi process. Stage 4 consists of a face-to-face consensus meeting of international experts and patient/family representatives in order to define, endorse, and propose the final Core Outcomes Set. Discussion: Core Outcome Sets aim at promoting uniform assessment of care outcomes in clinical practice as well as research. If consistently employed, a robust set of core outcomes for the end of life, and specifically for the dying phase, defined by relevant stakeholders, can ultimately be translated into best care for the dying person. Patient care will be improved by allowing clinicians to choose effective and meaningful treatments, and research impact will be improved by employing internationally agreed clinically relevant endpoints and enabling accurate comparison between studies in systematic reviews and/or in meta-analyses.
