The poster presented at the 4th Croatian Symposium on Invasive Species held in Zagreb on 29-30 November 2021 presents a comparison of the economic and labour effort for mapping H. tuberosus by two methods (aerial mapping and traditional ground field mapping) and the developed protocol for identification and monitoring IAPS by drone.

Here we present the preliminary research results of the Croatian Science Foundation project NATURALLY (IP-2020-02-6899), intending to explore the potential of natural extracts of alien invasive plant species for potential application as phytopharmaceuticals. In our study, we used the method of high-performance liquid chromatography with reversed ph...

In this study, we evaluated total phenolic content (TP), total flavonoids (TF), and total non-flavonoids (TNF) in 90% methanol dry leaf extracts of four invasive plant species using spectrophotometric methods. We also determined the antioxidative capacity (AC) in 70% ethanolic dry leaf extract by three standard assays (ABTS, DPPH, and FRAP).

Dittrichia viscosa (L.) Greuter is a shrub native to the Mediterranean, however, declared as a very invasive species in Australia and North America. Environmental (climatic) and socio-economic (land abandonment) changes can trigger different adaptive mechanisms and cause changes in species behavior, influencing invasion dynamics. Motivated by the r...

The Asiatic string cottony scale Takahashia japonica Cockerell (Hemiptera, Coccomorpha, Coccidae) is a species native to Japan. The first record in Europe was observed in Italy in 2017 and again in UK in 2018. In this paper, we provide an overview of the first record of T. japonica in Croatia. First appearance of T. japonica was in 2019 in Pula (Is...

Here we present a case study of biological recording of sea urchins (Paracentrotus lividus, Arbacia lixula and Sphaerechinus granularis) in the Adriatic Sea using a participatory citizen model. “Where did the sea urchins disappear?” campaign was launched in July 2019 by the Invasive Species Centre (ISC) at the Institute of Agriculture and Tourism P...
