The first EVOLTREE Conference, hosted by WSL Birmensdorf (Switzerland) from 14-17 September, 2021, focuses on the genomics and adaptation of trees and interacting species from evolutionary, demographic, and ecological perspectives.

Contributions that apply innovative approaches and consider the relevance of their research in the context of biodiversity conservation through natural dynamics or silvicultural interference are welcome.

Registration and abstract submission is now open! https://conf.wsl.ch/evoltree/

EVOLTREE is a European network of research institutions and universities engaged in studying the evolution and functioning of forest ecosystems, in particular trees as the foundation species in forest stands. A prime topic in the face of ongoing climate change is to elucidate how trees, together with their associated organisms such as mycorrhizal fungi, respond to rapid environmental changes.

EVOLTREE has launched a series of online seminars about polygenic adaptation in trees and other organisms. The events will be streamed on YouTube and recorded.

Variation in complex phenotypic traits, like growth, is known to be driven by many genes. For example, it has been shown that the height of humans is associated with thousands of regions in the genome. Approaches for detecting polygenic signals from genomic data, however, are still scarce and rarely applied. This seminar series aims to promote an exchange of knowledge among scientists working on polygenic adaptation in disparate organisms with the objective of facilitating development and wider uptake of the latest approaches.

Programme

28 October 2020, 16:30-18.00 CET
Jonathan Pritchard: ‘Architecture and adaptation of human complex traits’

4 November 2020, 16:30-18.00 CET
Emily Josephs ‘The evolutionary forces shaping gene expression variation’

18 November 2020, 16:30-18.00 CET
Sam Yeaman ‘A tale of two architectures: Local adaptation under migration-selection balance’

25 November 2020, 16:30-18.00 CET
Neda Barghi: ‘Polygenic adaptation in Drosophila’

Our B4EST webinar held on 10 December introduced the Planter’s Guide.

The Planter’s Guide is a web-based decision support tool for improved Scots pine forest reproductive material (FRM) in Sweden and Finland. By selecting a regeneration site, the Planter’s Guide ranks all available seed orchards according to their predicted areal production over a rotation. However, as both growth and survival ability are shown separately the user can use this information for a more detailed selection.

December 10-13, 2019 at INIA, Madrid, Spain

As part of Gentree project (www.gentree-h2020.eu) dissemination and training activities, this workshop aims to provide a general conceptual background and hands-on experience in the analysis of molecular and quantitative genetic data, and of trait-based species distribution models (ΔTraitSDM), for conservation genetics relevant problems in tree species. Emphasis will be on statistical and modelling tools, rather than on the data acquisition process.

Topics will cover: summary of relevant population genetic parameters in conservation; estimation of effective population size and inbreeding; estimation of genetic connectivity and introgression; surveying genome-wide molecular diversity in natural populations; inferences of selection and historical demography; design and analysis of common garden experiments to assess adaptive quantitative genetic variation and phenotypic plasticity; estimation of additive genetic variance, heritability and evolvability; trait-based species distribution models (ΔTraitSDM) as forecast tools for genetic conservation.

Registration is free and the organization will cover the accommodation expenses, breakfast and lunches of up to 20 students.

The application deadline is July 25th, please visit the workshop’s website below for application instructions, the list of instructors, contact information, and other details:

Organised by the GENTREE project.
Participants: forest managers and practitioners, forest breeders
Deadline for application: 15 June 2019

Tree breeders must often consider conservation of genetic diversity, while at the same time they attempt to maximize genetic response to selection. This challenge is common to management of populations for both gene conservation and elite breeding, as well as to assembly of deployment populations, such as seed orchards and mixtures of selected clones. GenTree has developed several tools and advanced methods for addressing this challenge.

The purpose of this course is to provide participants with the background and user-skills necessary to apply these tools correctly in the context of applied forest tree breeding programs. Different tools for “optimum selection” will be presented, such as “OPSEL”, which uses state-of-the-art mathematical approaches to optimize selection with a specified constraint on gene diversity. Other approaches include managing genetic diversity at the genomic level to guarantee short- and long-term genetic gains or levels of fitness, notably under genomic-evaluation scenarios.

After “optimizing” genetic contributions to a selected population, the practitioner still faces the daunting task of preparing mating plans that respect these contributions, while avoiding excessive relatedness between parents. A generalized tool “XDesign” makes this task straightforward, allowing the user to specify a threshold on the maximum acceptable coancestry between mates.

The training will show the concepts and functioning of several strategies to account explicitly for diversity across the genome of candidates during selection and mating steps in the context of breeding and conservation programs. Breeding strategy evaluation will be addressed with R-scripts and the simulation package “POPSIM’.
