The 2026 spring-summer activities of the Pollination Ecology Workgroup include participation in public events as well as various fieldwork.
Tomorrow, April 21, the Oecomess organized for students will take place in Oecologicum (J. Liivi 2). The event offers those interested the opportunity to get acquainted with the working groups operating within different departments and the topics of their thesis. The topics of the Pollination Ecology Workgroup's bachelor's and master's theses with their supervisors are listed here.
A few days later, from April 23 to 26, the working group will participate in the Rural Fair at the Tartu Fair Center (F. R. Kreutzwaldi 60). This is one of the largest rural and agricultural events in Estonia, where the working group will also introduce its research to a wider audience. Come visit us at booth C-40!
At the end of April, fieldwork will begin across Estonia under the leadership of the working group's scientists. During these, queen bumblebees will be observed searching for nest sites and data will be collected using disc traps to assess the condition of wild bees in agricultural landscapes (the fieldwork leader of the project funded by the Estonian Environmental Investment Centre is Research Fellow in Pollination Ecology Mari-Liis Viljur). Also, samples of various plant species will be collected from restored algal beds under the leadership of Research Fellow in Landscape Genetics Iris Reinula. “The samples obtained will be used to study the genetic and species diversity of plant species and the impact of restoration on them against the background of previously collected data,” said Iris Reinula.
The head of the workgroup, Associate Professor in Macroecology Tsipe Aavik and Iris Reinula will participate in the PopBio conference on plant population biology, which will take place from 6 to 9 May, this time in the city of Marburg, Germany. Iris Reinula will present the first results of landscape genetic analyses of medium-sized bluegrass (Briza media) at the conference. Marie, the representative of the FuncNet project led by the working group, will also give a presentation at the conference, talking about the landscape genetic studies conducted in the project with the Cowslips (Primula veris).
After PopBio, Tsipe Aavik will visit the Molecular Ecology Conservation Genetics Working Group at the University of Regensburg and hold a seminar on the research being carried out in the Pollination Ecology Working Group. This week, Senior Specialist for Research Projects Sigrid Ots will give a presentation at the Integrated Restoration Projects Network conference in Warsaw, where she will also talk about the activities of the “ForEst&FarmLand” project, which is being implemented with the participation of members of the Pollination Ecology Workgroup as well.
In June, the defenses of the final theses will take place at the University of Tartu. The schedule of the defenses of the Institute of Ecology and Earth Sciences can be found here. Rafael Somelar, will defend his master’s thesis, while Kärg Valner (in zoology) and Anne-Mai Adamberg will defend their bachelor’s theses. Tsipe Aavik will participate in the defenses as a member of the evaluation committee.

In an article published on ERR's science news portal Novaator, Tsipe Aavik, head of the Pollination Ecology Workgroup and Associate Professor of Macroecology, discusses how the pan-European cowslips campaign, which began in Estonia, not only enabled the gathering of new ecological knowledge but also prompted a look at citizen science itself. An analysis of interviews with the campaign's co-organizers revealed that stumbling blocks can include a lack of time, rigid funding rules, and regional cultural differences.

During the annual orchid exhibition at the University of Tartu Botanical Garden, a seminar was held for the second year in cooperation with the Estonian Orchid Conservation Club, offering fascinating presentations for both beginner orchid enthusiasts and experienced orchid experts.
The theme of this year's seminar was "Orchids and Pollinators". The topics discussed included the relationships between orchids and other organisms, the vulnerability of orchids in the context of climate change, their pollination strategies, and the challenge of photographing orchid bees.
“In Estonia, orchid pollinators have been studied very little, as the life cycle of orchids is quite complex and their survival rate is extremely low compared to many other plant groups. Therefore, growing orchids from seeds seems impossible – after all, orchids in nature need the help of a fungus, because the seed lacks endosperm,” says Anne-Mai Adamberg, president of the Orchid Conservation Club and also a bachelor's student in the Pollination Ecology Working Group, who gave an overview of the pollinators of Estonian orchid species.
The presentations given at the orchid seminar held on March 5 can be found here: https://natmuseum.ut.ee/et/uudis/nuud-jarelvaadatav-botaanikaaia-orhideeseminar.

Since being Estonian and Estonian culture are closely intertwined with nature, both contemporary and earlier literature often includes descriptions of plants growing in forests, meadows, bogs and fields. In the spirit of this Mother Language Month, it is fitting to see under what names the cowslips, the emblem of the pollination ecology working group, has found a home in the Estonian language and literature.
The recently published poetry collection "Hortus poeticus. A selection of Estonian plant poetry" contains poems about 140 plants growing in Estonia, among which the common cowslips (Primula veris) is also represented through Kersti Merilaas' poem.
According to the book "Estonian plant names", the cowslips´ has as many as 208 folk names, of which Gustav Vilbaste has recorded 116:
härjalaatsad, härjakaapst, härjakapsas, härjakatsud, härjakadsad, härjakaatsad, härjakats, härgkaatsad, jaani-lill, juudipüksid, kaatsad, kanna kaltso, kana-kaltsa', kanakaltsud, kanakollad, kanapasa-lill, kanna warbas, kana-warwad, kanavarbad, kassikäpp, kevadevõti, kikaspüks, kikkakaatsa, kikkapüks, koisid viinalillid, koisi viinalilled, koldsed viinalilled, kolsi wina lillid, kollane tinaneitsi, kollanokk, kotsid wina lilli, konnaninn', kortled, kukekaatsad, kukekalts, kukekannus, kukepüks, kukesõrmkindad, kukulinnu-käekaatsas, kukulinnu ätses, kukulinnu-sõrmikindad, kuldkannike, kurekaats, käkaadsed, käekaats, käekaatse, käekarts, käekatsas, käägats, käekatse, käekaasuke, käekaisuke, käekaitsas, käekaitse, käekaitsja, käekasu, käekasukas, käekaltsud, käokaatsad, käokannus, käokeel, käukäpp, metstubakas, mäelilled, nattalillid, natt-nunnid, neitsipisar, neitsi-tinnad, neiulill, nurmekaasuke, nurma nudkud, nurmenukk, nurmenupp, nurmekäpp, Peetruse võtmed, Peetruse võtmelilled, nullernukk, piimapisar, pääsukese-silm, pääsulill, saksapüks, savilill, sõrmlill, sõrmkinnas, sõrmelill, sõrmiklill, sõrmkübar, taevavõti, titepüksid, titevarrus, valurohi, viinalilled, võtmelill, võtmalill, võtmekimp, ärgats, õlkalill, rotsid wina lilli, kanakoiv, kanakoole, kanapasalill, kanaperse, kikkamunn, kikkapael, koeratubakas, kukehari, kukevarvas, pasklill, piimakinnas, piimapüks, priimula, saviõis, taevasilm, tubak, vanapoisi silmavesi, vargapoisi varvas, võipätt, võipätakas.
Have a beautiful upcoming Mother Language Day!

In early February, an international symposium “Semi-natural grasslands in the European agricultural landscape: plants, pollinators and people in the winds of change” took place, where participants discussed the role of semi-natural grasslands and other grassland communities in maintaining the multi-layered biodiversity of Europe’s agricultural landscapes.
The presentations provided an overview of ecological processes and patterns in semi-natural grasslands both below- and aboveground, spanning genetic to landscape scales. Among other things, it was discussed how these valuable communities in terms of both biodiversity and socio-economic benefits could continue to be seen in our landscapes despite changes in land use patterns. The symposium brought together both state representatives and renowned scientists from Estonia and several parts of Europe, who shared knowledge and experience and sought solutions to support more sustainable land use in their presentations.
The presentations from the symposium are now available for viewing and downloading online. You can find them here: https://ecobank.ut.ee/symposium.html.
We would like to thank all the speakers and participants once again for the fruitful day of discussion!

Until very recently, intraspecific diversity, i.e., genetic diversity, remained unnoticed in agreements on biodiversity conservation. Yet, this invisible biodiversity is the foundation for populations to cope with environmental changes and hence requires special attention.
The Convention on Biological Diversity was recently amended by adding genetic diversity as one of the key components in assessing biodiversity. This will entail a first-time obligation for countries that have ratified the convention to report on the status of the genetic diversity of species. The first-ever monitoring of genetic diversity is supported by the pan-European COST network GENOA, where Estonia is represented by Iris Reinula, a research fellow in landscape genetics at the Pollination Ecology workgroup at the University of Tartu, and Associate Professor Tsipe Aavik, the head of the Pollination Ecology workgroup. Last week, Iris Reinula presented the monitoring framework at the Nature Conservation conference organized by State Forest Management Centre in Saaremaa.
“In principle, genetic data is not always necessary for the assessment – indirect proxies can be derived from other well-known measures, such as population sizes,” said Iris Reinula, who spoke about mapping invisible biodiversity using the example of Estonia at a recent nature conservation conference. “We are currently collecting data from various data sources, but this has proven to be more difficult than expected. Data is insufficient for many species; it is quite scattered or collected using different methodologies. However, we are confident that for many species, the status of genetic diversity can be assessed and accounted for in nature conservation without picking up a pipette, i.e., indirectly using population sizes and other already available data.”
For comprehensive species conservation, more attention must be paid to ensuring and monitoring genetic diversity in the future. To this end, indicators are being developed that can make the hitherto complex assessment of genetic diversity easier and take it out of the laboratory.
The RMK nature conservation conference “Restoration and protection of habitats” took place on 30–31 October 2025 in Kuressaare.
