Pregled metod za določanje številčnosti prostoživečih parkljarjev
Katarina Flajšman, Urša Fležar, Boštjan Pokorny, Klemen Jerina, 2019, original scientific article

Abstract: Poznavanje absolutne in/ali relativne številčnosti prostoživečih parkljarjev je eden pomembnejših vhodnih podatkov, ki nam omogoča njihovo učinkovito trajnostno upravljanje. V večjem delu Slovenije so prostoživeči parkljarji gospodarsko, motivacijsko in ekološko najpomembnejša skupina divjadi. V procesu njihovega upravljanja trenutno ni uveljavljenih standardnih in rutinskih metod, na podlagi katerih bi lahko zanesljivo ocenjevali absolutno in/ali relativno številčnost na vsakoletni ravni. Metod za spremljanje številčnosti populacij prostoživečih parkljarjev je veliko; pri izbiri najustreznejše je treba upoštevati določene kriterije. Najpomembnejši kriteriji za izbiro metode so obravnavana vrsta parkljarjev, značilnosti habitata, velikost območja, gostota populacije, možnost kontrole in nenazadnje tudi stroški. V Sloveniji je bila za ocenjevanje številčnosti srnjadi in jelenjadi že v rabi metoda štetja kupčkov iztrebkov, poleg katere bi bila primerna tudi metoda kilometrskega indeksa. Pri divjem prašiču za najbolj zanesljive metode veljajo uporaba foto pasti, štetje na pogonih in daljinsko vzorčenje s pomočjo termovizije, pri gamsu pa štetje s tal in monitoring iz zraka.

Action A3 : analysis of spatial connectivity and preparation of environmental impact assessment guidelines : prepared within A3 action of LIFE DINALP BEAR Project (LIFE13 NAT/SI/0005)
Mariano Rodriguez Recio, Klemen Jerina, Felix Knauer, Anja Molinari-Jobin, Claudio Groff, Đuro Huber, Paolo Molinari, Luca Pedrotti, Stefano Filacorda, 2018, final research report

Abstract: As for other large carnivores in Europe, the brown bear shows a trend of recovering under different management scenarios. However, this recovery comes with specific biological and conservation requirements at individual and population levels often followed by conflicts in a highly humanized continent. To foresee conflicts with humans and to facilitate decisionmaking, spatially-explicit research is required to identify potential habitats and the connectivity of fragmented bear populations. First, we conducted multiscale modeling based on scale-integrated resource selection functions (SRSFs) to identify drivers shaping the spaceuse of three bear populations/demographic units (Trentino-Swiss, pre-Alps, and Dinaric), and across 3 scales of space (population distribution, home range establishment, and use of individual home range). Secondly, we also conducted an analysis of the connectivity patterns of suitable habitat patches (nodes) to identify the potential importance of each node to contribute to individual mobility, survival, and population connectivity. Lastly, to support further environmental impact assessment analyses, we identified the most plausible least-cost paths connecting different areas of the same large patch with itself and surrounding patches. Using topographic, landcover, and anthropogenic predictors, our analytical approach transcended from scale dependence bias to produce a predictive map on habitat suitability while delivered information on habitat selection trends for each population. Bears mostly selected forest habitats in all the populations; however, habitat selection differed for the other variables among populations and scales, especially in the Trentino area where the species selected the most intricate topography. Predictive maps revealed a broad range of suitable but fragmented patches of bear habitat. The largest and most important patches for connectivity occurred in the current distribution range of the species, with the most suitable habitat lying in the pre-Alpine and Dinaric populations. Connecting viable patches to host female homeranges is possible through stepping-stone patches of corridors reachable within the estimated dispersal distance of females. Unified transnational decision-making is required for the conservation of stepping-stone patches, facilitate bear mobility, and ultimately connect bear populations.

Pregled prilagajanja rabe prostora rjavega medveda (Ursus arctos) na antropogene motnje
Maja Mohorović, Miha Krofel, Klemen Jerina, 2017, original scientific article

Abstract: Za dolgoročno varstvo velikih zveri je pomembno razumevanje mehanizmov njihovega prilagajanja na prisotnost človeka, vključno z antropogenimi spremembami prostora. Rjavi medved (Ursus arctos) je za tovrstne raziskave zaradi holarktične razširjenosti in pojavljanja v različnih okoljih dobra modelna vrsta. S pregledom raziskav s celotnega območja razširjenosti vrste v svetu smo preučevali, kako medvedi prilagajajo rabo prostora intenziteti človekovih posegov v prostor. Medved se v splošnem antropogenim strukturam izogiba, še posebej stalno poseljenim območjem in močneje obremenjenim prometnicam. Zaznali smo tudi trend, da se medvedi na območjih z večjo gostoto prebivalstva pogosteje izogibajo antropogenim strukturam. Primerjava med Evropo in Severno Ameriko je nakazala večje izogibanje medvedov urbanim površinam v Evropi, pri drugih tipih antropogenih struktur pa so bile razlike med kontinentoma majhne. Pri primerjavi študij je vendarle potrebna previdnost, saj je večina obravnavanih raziskav temeljila na ugotavljanju relativne rabe prostora (t.j. raba glede na razpoložljivo), statistike absolutne rabe pa niso dovolj pogosto podane. Za ovrednotenje dejanske razlike v rabi prostora posameznih populacij medvedov iz okolij z različno stopnjo antropogenih motenj zato predlagamo analizo surovih podatkov.
