Biodiversity Conservation and Forest Management - Trends and Perspectives

Special Issue of Forests edited by Dr. Anna K. Jasinska

The geographical ranges of plants in the world depend on many factors. One of the most important over the millennia has been, and is, the climate. The disappearance or expansion of the area covered by woody species as the foundation of forest ecosystems largely affects other species of plants, animals or fungi, and contributes to changes in the microclimate, matter circulation, and others. As a result of climate change, many species are doomed to extinction, and others may seize the opportunity to enlarge the area that they currently occupy. In both cases, scientists and foresters are faced with the challenges of properly preparing for these changes, examining them, trying to predict their effects, counteracting them and supporting selected species in expansion. The aim of the Special Issue will be to explore different aspects of forest ecology and biology, evolution and biogeography of woody plant species.

For this Special Issue of Forests, we therefore warmly welcome contributions (original research papers, reviews, perspectives and opinions) from different fields of research. Forests receives an IF of 2.762.

Special Issue
Genetic Diversity and Conservation of Woody Species

Special Issue of Plants edited by Prof. G. Kozlowski

Trees and other woody plants, such as shrubs and lianas, form the principal components in forests and many other ecosystems on our planet. However, the future of many trees and shrubs is uncertain. Ten of thousands of species are threatened by overharvesting, non-native pests and diseases, changes in accelerated land use and climate warming. Many aspects of their biology, ecology and biogeography are still unexplored, or insufficiently understood. These knowledge shortfalls, concerning their genetic diversity, for example, significantly hinder development of protection strategies and elaboration of efficient action plans. This issue, dedicated to this very diverse group of plants, aims to encourage on-going research and conservation efforts worldwide.

For this Special Issue of Plants, we therefore warmly welcome contributions (original research papers, reviews, perspectives and opinions) on woody species and their conservation, from different fields of research, such as molecular biology, conservation biology, ecology, biogeography and physiology. Plants receives an increased IF of 2.762 and falls into the highest quartile (Q1) in the category 'Plant Sciences'.

Master Thesis on Pinus cembra

Field-work 2020

Pinus cembra is an outsider among the European pine species: it is a five-needle pine, closely related to the Siberian and East-Asiatic P. sibirica, P. pumila and P. koraiensis. The isolated populations of P. cembra in canton of Fribourg possess an enormous biogeographic and conservation value. Vincent Sonnenwyl (University of Fribourg) started the field work for his Master Thesis (2020-2021) focused on (1) History and extent of artificial afforestation in canton of Fribourg; (2) Distribution and characterization of all populations in canton of Fribourg; (3) A genetic study in order to assess the differences in genetic diversity between the artificial stands and natural populations.


Our research and conservation activities

  1. Basic and applied research on relict, rare and/or threatened woody species (biogeography, conservation biology, phylogeny, phylogeography, population genetics, population structure, dendrochronology, etc.).
  2. Conservation actions (in situ and ex situ conservation), action plans and conservation status assessments.
  3. Capacity building (teaching, internships, exchange of students and young scientists, etc.).
  4. Public awareness and outreach (exhibitions, books, workshops, etc.).
  5. Iconographic collections (scientific photography, scientific drawings, etc.)
