Wow, we are so happy that we will finally come together again after wait- ing for so long! This 33rd meeting of our Specialist Group Plant Population Biology of the Ecological Society of Germany, Austria and Switzerland (GfÖ) had to be postponed by one year due to the world- wide Covid-19 pandemic and has now been re-organized as an online conference by our colleagues in Prague. They have done an amazing job in adjusting a physical meeting into a virtual one. We are grateful for their time and efforts to realize this. We also thank the keynote speakers – Markus Fischer, Thomas Giesecke, Petr Kuneš, Vojtěch Novot- ný, Christina Richards and Vigdis Vandvik – for their upcoming contributions in five sessions covering a broad range of themes and for their willingness to wait for a year. In addition, this year’s participants, contributing a total of 32 oral and 65 poster presentations, will fill this conference with exciting con- tent that feeds our common interests and lively discussions. Many presenters are young scientists, for whom this conference aims to provide a welcoming stage. This conference is indebted to its sponsors, in particular the directorate of the GfÖ for their financial support, allowing us to realize this virtual PopBio meeting in a professional way. We are sure that this virtual version of PopBio will greatly contribute to the scientific as well as the so- cial exchange and we look forward to meet you all, the usual participants as well as the new ones. Our meeting will be different from previous years, yes, but PopBio 2021 will still be one of those meetings that we will remember as we do past PopBio meetings. Enjoy!

In this study, we performed a re-visitation study using historical and newly collected vegetation plots to explore the primary trends in the floristic, ecological, and structural features of Mediterranean Pinus mugo krummholz over past decades. The plant community composition over time (1992 vs. 2016–17) was analyzed by a detrended correspondence analysis followed by a statistical comparison of time steps and an analysis of the contribution of each species to temporal differences. Ecological and structural changes were analyzed by a permutational multivariate analysis of variance followed by a post hoc comparison. We observed relevant changes in the floristic composition, structure, and ecological characteristics of Pinus mugo scrub.

(2015): The role of biodiversity conservation in education at Warsaw University Botanic Garden. – Thaiszia – J. Bot. 25 (Suppl. 1): 35-44. – ISSN 1210-0420. Abstract: The Botanic Garden of Warsaw University, established in 1818, is one of the oldest botanic gardens in Poland. It is located in the centre of Warsaw within its historic district. Initially it covered an area of 22 ha, but in 1834 the garden area was reduced by 2/3, and has remained unchanged since then. Today, the cultivated area covers 5.16 ha. The plant collection of 5000 taxa forms the foundation for a diverse range of educational activities. The collection of threatened and protected Polish plant species plays an especially important role. The Botanic Garden is a scientific and didactic unit. Its educational activities are aimed not only at university students, biology teachers, and school and preschool children, but also at a very wide public. Within the garden there are designed and well marked educational paths dedicated to various topics. Clear descriptions of the paths can be found in the garden guide, both in Polish and English. Specially designed educational games for children, Green Peter and Green Domino, serve a supplementary role.

Turner Department of Soil and Crop Sciences In partial fulfillment of the requirements For the Degree of Doctor of Philosophy Colorado State University Fort Collins, Colorado Fall 2012 Doctoral Committee: Advisor: Sarah Ward Christopher Richards David Steingraeber George Beck Sharlene Sing Copyright by Marie Frances Sundem Turner 2012 All Rights Reserved ABSTRACT VIABILITY AND INVASIVE POTENTIAL OF HYBRIDS BETWEEN YELLOW TOADFLAX (LINARIA VULGARIS) AND DALMATIAN TOADFLAX (LINARIA DALMATICA) Although outcomes of hybridization are highly variable, it is now considered to play an important role in evolution, speciation, and invasion. Hybridization has recently been confirmed between populations of yellow (or common) toadflax (Linaria vulgaris) and Dalmatian toadflax (Linaria dalmatica) in the Rocky Mountain region of the United States. The presence of hybrid toadflax populations on public lands is of concern, as both parents are aggressive invaders already listed as noxious weeds in multiple western states. A common garden experiment was designed to measure differences in quantitative (shoot length, biomass, flowering stems, seed capsule production) phenological (time of emergence, first flowering and seed maturity) and ecophysiological (photosynthesis, transpiration and water use efficiency (WUE)) traits for yellow and Dalmatian toadflax, F1 and BC1 hybrids, as well as natural field-collected hybrids from two sites. Genotypes were cloned to produce true replicates and the entire common garden was also replicated at two locations (Colorado and Montana); physiological data were collected only in Colorado. All genotypes grew larger and were more reproductively active in Colorado than in Montana, and hybrids outperformed parent taxa across vegetative and reproductive traits indicating heterosis.

  • The Evolution of Pyrrolizidine Alkaloid Diversity Among and Within Jacobaea Species

Box 9505, Leiden 2300 RA, The Netherlands 2RIKILT‐Wageningen University & Research, Akkermaalsbos 2, P.O. Box 230, Wageningen 6700 AE, The Netherlands *Author for correspondence. E‐mail: [email protected] Received 28 April 2020; Accepted 27 July 2020; Article first published online 8 August 2020 Abstract Plants produce many secondary metabolites showing considerable inter‐ and intraspecific diversity of concentration and composition as a strategy to cope with environmental stresses. The evolution of plant defenses against herbivores and pathogens can be unraveled by understanding the mechanisms underlying chemical diversity. Pyrrolizidine alkaloids are a class of secondary metabolites with high diversity. We performed a qualitative and quantitative analysis of 80 pyrrolizidine alkaloids with liquid chromatography‐tandem mass spectrometry of leaves from 17 Jacobaea species including one to three populations per species with 4–10 individuals per population grown under controlled conditions in a climate chamber. We observed large inter‐ and intraspecific variation in pyrrolizidine alkaloid concentration and composition, which were both species‐specific. Furthermore, we sequenced 11 plastid and three nuclear regions to reconstruct the phylogeny of the 17 Jacobaea species. Ancestral state reconstruction at the species level showed mainly random distributions of individual pyrrolizidine alkaloids. We found little evidence for phylogenetic signals, as nine out of 80 pyrrolizidine alkaloids showed a significant phylogenetic signal for Pagel's λ statistics only, whereas no significance was detected for Blomberg's K measure.
