Estimating the most effective and economical pheromone for monitoring the European spruce bark beetle
Maarten De Groot, Marija Kolšek, Andreja Kavčič, Nina Šramel, 2021

Povzetek: In recent decades, there have been an increasing number of outbreaks of Ips typographus in Europe. A large amount of sanitary felling has taken place, with significant economic and ecological consequences. In order to anticipate such large%scale outbreaks, an effective monitoring system should be set up. One important aspect of monitoring is deciding which pheromone to use. Therefore, we decided to test five different commercially available pheromone lures under different disturbance conditions: Pheroprax%, IT Ecolure Extra%, Ipstyp%, Ipsowit% and Typosan%. We investigated the ability of the pheromones to distinguish between disturbed and undisturbed locations, their cost%efficiency ratio, and side effects such as bycatch abundance and composition. We set 50 traps in two areas with sites that were disturbed and undisturbed by windstorms. We collected the catch from traps every 1%2 weeks from the end of March until the end of September in 2019. We found that IT Ecolure Extra%, Ipsowit% and % Pheroprax% caught the most I. typographus and best showed changes in the trap catch of I. typographus throughout the whole season. There was a low amount of bycatch (<6% of the total catch) and a low number of predators (a few specimens), but some groups seem to prefer certain pheromones. The cost of the pheromones increased with their effectiveness. However, pheromone costs are low relative to the personnel costs involved in setting traps and collecting the catch. Based on all of the gathered data, we created an index which helps to assess the cost%efficiency of the five chosen commercially available pheromones. We also present guidelines on how to make such an index to assist other researchers in choosing the right pheromone for monitoring populations of I. typographus or other bark beetle species.

Go for Mura : upravljanje gozdnih habitatnih tipov in vrst v izbranih območjih Natura 2000 ob Muri
2016

Povzetek: Vsebina pričujoče publikacije pokriva problematiko gospodarjenja z gozdovi v območjih Natura 2000. V prvem delu je predstavljeno stanje gozdov v študijskih območjih (stanje gozdnih habitatnih tipov, njihove strukturne lastnosti, bolezni in invazivne rastline, stanje in perspektiva hrasta doba, kakovost vode). Sledi opis stanja obravnavanih živalskih vrst (bober in vidra, dvoživke, ptice, hrošči) in izvedenih varstvenih ukrepov za izboljšanje ohranitvenega stanja gozdnih habitatnih tipov ter habitatov bobra in vidre. V zadnjem delu pa so predstavljeni delo z javnostmi in njihovo mnenje o Naturi 2000, koncept upravljavskega načrta za gospodarjenje z gozdovi v območjih Natura 2000 in prakse, ki se razvijajo v tujini.
Ključne besede: Natura 2000, gospodarjenje, habitatni tip, Mura, poplavni gozd, Slovenija
