Ekosistemska vloga, pomen in vplivi divjega prašiča (Sus scrofa L.) = Ecological importance and impacts of wild boar (Sus scrofa L.)Pokorny, Boštjan ; Jelenko Turinek, IdaDivji prašič (Sus scrofa L.) je v srednjeevropskem prostoru domorodna živalska vrsta, ki se je skozi evolucijski proces razvijala in s svojo aktivnostjo opravljala številne pomembne ekosistemske ... funkcije. Celovit pregled opravljenih raziskav in vplivov divjih prašičev na različne sestavne dele ekosistemov (tla, vode, rastlinstvo, glive in živalstvo) kaže, da ima vrsta veliko ekosistemsko vlogo in pomembno vpliva na stanje ter razvoj kopenskih (v manjši meri pa tudi vodnih) ekosistemov. V literaturi so najpogosteje omenjeni vplivi z (za ljudi) negativnim predznakom, npr. neželene spremembe kemijskih in fizikalnih lastnosti tal, oteženo pomlajevanje gozdov, zmanjševanje rastlinskega pokrova, širjenje tujerodnih vrst in patogenih organizmov, plenjenje redkih in ogroženih živalskih vrst, povzročanje medvrstne konkurence, hibridizacija z domorodnimi podvrstami, prenos bolezni na druge živalske vrste itn. Vendar divji prašič opravlja v okolju tudi številne pozitivne vloge, med katerimi so še zlasti pomembne: ustvarjanje pestrejših habitatnih razmer in dolgoročno večanje biotske raznolikosti, širjenje rastlinskih semen in podzemnih vrst gliv z zoohorijo, zmanjševanje številčnosti nekaterih gospodarsko problematičnih vrst nevretenčarjev, odstranjevanje mrhovine in zagotavljanje pomembnega prehranskega vira za velike zveri. Vendar so naštete koristi praviloma spregledane, divji prašič pa je obravnavan skoraj izključno kot problematična/škodljiva vrsta. V prihodnje je zato treba ekosistemsko vlogo divjega prašiča sistematično in objektivno obravnavati, vplive, ki jih ima vrsta, pa prepoznati, podrobno raziskati in tako vrsto objektivno predstavljati širši javnostiSource: Zlatorogov zbornik. - ISSN 2232-6499 (Letn. 2, št. 2, 2013, str. 2-30)Type of material - article, component part ; adult, seriousPublish date - 2013Language - slovenianCOBISS.SI-ID - 1157334
