Workshop on Ne, effective population size
Half day online workshop arranged by G‐BiKE on recent issues relating to contemporary effective population size (Ne) in relation to monitoring of genetic diversity. The aim of the workshop is to highlight some new important insights that is of relevance in applying Ne as an indicator for conservation genetic status. To discuss these topics with the aim to explore if there are some general recommendations for practical management that can be agreed on.

Microbial communities inhabit every niche in nature. They are a great and often unaccounted for modulators of chemical and biochemical processes affecting all levels of biological organization. They are active in the soil and water, or as symbionts of other organisms. They are important providers of ecosystem services, either directly, by e.g. cycling minerals and compounds in specific ways, or indirectly, by e.g. maintaining the health of other organisms, or by controlling their populations. Molecular tools, which are culture independent, allow us to sensitively profile the taxonomic composition of communities, their potential genetic toolkit alongside active metabolic pathways, as individual strains and species or as communities, and most importantly, the interaction of these levels of diversity with environmental factors such as temperature and pressure, pH, humidity and moisture, salinity, the concentration of specific metabolites, etc. Understanding microbial populations or communities with genetic tools can thus inform nature conservation, but also agriculture, industry and even tourism.

The aDNA contribution to the CBD post-2020 Global Biodiversity Framework, Online meeting
Background Since the first Convention on Biological Diversity (CBD) in 1992, biodiversity has been defined as the total variation of life on planet Earth at three levels: genes, species and ecosystems. Today we face dramatic biodiversity loss due to the combined effects of land use and climate change. This loss is basically calculated in terms of number of species, but very little is known about loss of diversity at the genome level. Nonetheless, roughly speaking, genetic diversity within species is the necessary condition for any adaptation to occur and it is, thus, of particular relevance in the so-called Anthropocene. The relevance of genetic diversity in biodiversity protection and management has been only rarely included in policies and regulations. This seems to be the case for the CBD post-2020 Global Biodiversity Framework too. To this end, the COST Action G-BiKE together with GEO-BON and IUCN has recently developed three genetic indicators to be included in the next strategy (Hoban et al, 2020): 1) The number of populations [or breeds] within species with an effective population size > 500 compared to the number < 500. 2) The proportion of (sub)populations [or geographic range] maintained within species. 3) The number of species and populations in which genetic diversity is being monitored using DNA-based methods. In this one-day online workshop we aim to highlight how aDNA studies can play a pivotal role for the practical implementation of the genetic indicators, especially of 1) and 2). Through key lectures and specific fora, we will present how aDNA studies are already poised to make these indicators highly informative in the light of CBD post-2020 Global Biodiversity Strategy.

WG2 Workshop, Tovetorp, SWEDEN
To answer how humans have affected genetic diversity across species, both positively and negatively, a group of G-BiKE members teamed up with other conservation genetics specialists to embark on a global meta-analysis of trends in genetic diversity, on a scale never attempted before. For this to happen, they needed to screen a shortlist of more than 30 thousand scientific articles that may contain valuable genetic trend data, before actual data analysis. All biomes and all multicellular taxonomic groups are included, with wild and domesticated species, endangered and common species, etc. The workshop in the ethological research station of Stockholm University at Tovetorp (Sweden) was set up to train 15 specialists of WG 2 (genetic monitoring) to screen papers and extract data in a standardized way for later analyses. Overall, they screened nearly 9000 articles, and extracted temporal genetic data from more than 200 species. They will continue to work on this programme for the next few weeks, albeit in isolation. Other G-BiKErs will be recruited with the aim of completing this endeavour in a couple of months.

WG4 Workshop: Biotech in conservation, Portorose, SLOVENIA
G-BiKE Working Group 4 hold a workshop entitled “New developments in the field of genomics technologies for solving practical conservation issues” in Portorož – Portorose, Slovenia from 4th-6th March 2020, organized by Prof. Dr. Elena Bužan (University of Primorska, Slovenia) and her group. There were 5 invited speakers and 15 participants from 14 different countries. During talks and discussions participants were provided an overview about: new gene modification techniques, gene drive techniques, recent biotechnology approaches, what contributes to inbreeding depression and how to translate research on to wildlife management. The role of biobanking, reproductive science and genomics for genetic rescue in highly endangered species was further discussed along with the importance of ancient DNA and how can we control malaria using gene drive mosquitoes. The main outcome of the workshop will be a scientific paper where we are supposed to provide an overview of potential use of new genomic technologies for addressing practical conservation issues in which we will emphasize what is feasibly now and what is far ahead as well as possibilities to implement these techniques in different countries.
