Strane, a posebno invazivne vrste često imaju negativan učinak na biološku raznolikost, ekonomiju, pa i ljudsko zdravlje. One su sposobne proizvoditi produktivno potomstvo i posjeduju potencijal širenja na značajnim površinama. Stoga je širenje invazivnih vrsta jedno od najvećih problema u zaštiti prirode. Praćenje rasprostranjenosti i procjena rizika invazivne vaskularne flore Požeške kotline vršeno je tijekom ljetnih mjeseci od 2017. do 2019. godine putem kombinirane procjene brojnosti i pokrovnosti. Istraživanjima je utvrđeno ukupno 34 invazivne svojte vaskularne flore kojima je pridružena porodica, životni oblik, geografsko porijeklo te je procjenjena faza procesa invazije. Za analizu povezanosti između nadmorske visine i pokrovnih vrijednosti invazivne flore Požeške kotline, primjenjena je multivarijantna statistička tehnika - CCA analiza. Najbrojnije vrstama su porodice Asteraceae i Poaceae. Analiza životnih oblika izdvojila je dominaciju terofita, ali i prisutnost hemikriptofita, fanerofita, geofita i hidrofita. Po porijeklu invazivne biljke pronađene u Požeškoj kotlini dolaze prvenstveno sa američkog područja, posebice Sjeverne Amerike, a zatim slijede one iz Azije i Afrike. Većina zabilježene invazivne flore nalazi se u stadiju ekspanzije tj. kolonizacije. Dobar dio je već naturaliziran, a dio je u fazi introdukcije. Nizinska područja do 200 m nadmorske visine pogoduju najvećem broju invazivnih biljaka. Samo manji broj biljnih vrsta je pozitivno koreliran s brežuljkastim područjima gdje se ističu vrste Phytolacca americana L. i Ailanthus altissima (Mill.) Swingle. Najviše zahvaćeni invazijom su ruderalna i poljoprivredna staništa.

Abstract Background Elongated rostra play an important role in the egg-laying of weevils, and its emergence plays a key role in the adaptive radiation of weevils. Eucryptorrhynchus scrobiculatus Motschulsky and E. brandti Harold co-occur on the same only host Ailanthus altissima, while their oviposition sites are different. In order to understand the adaptation between the rostra of the two weevils and their oviposition sites, the structural differentiation of the rostra in E. scrobiculatus and E. brandti was compared. Results The present study reveals that: (1) The rostra length of E. scrobiculatus and E. brandti was found to be correlated with body size, larger weevils have a correspondingly longer rostrum. The increase of rostra length may be a byproduct of larger weevils. (2) There were significant differences in the external shape of the two rostra, especially the shape of the mandibles of the mouthparts at the apex of the rostra used to excavate an oviposition cavity. (3) There was no difference in the size of the abductor muscles that control the extension of the mandibles, but there were significant differences in the size of the adductor muscles that control the contraction of the mandibles. Conclusions These structural differences reflect the functional potential ovipositional tactics of rostra, which is considered to be a response to the ecological demands of egg deposition, and also provide new insights into the coexistence of two weevil species in the same host A. altissima.

Abstract A. altissima, native to China, is a short to medium-size deciduous tree valued chiefly for timber, shade and urban amenity plantings. It is tolerant of drought, poor soils and pollution and so can be grown in difficult urban locations, although it is considered as a potentially weedy species in the USA (Shah, 1997). It is an aggressive pioneer species, characterized by rapid juvenile growth and prolific seed production and has a very high ability to coppice once established. It requires well-aerated and moist soils to produce good, single-stemmed trees.

Phytochemistry investigations on Ailanthus altissima (Mill.) Swingle, a Simaroubaceae plant that is recognized as a traditional herbal medicine, have afforded various natural products, among which C20 quassinoid is the most attractive for their significant and diverse pharmacological and biological activities. Our continuous study has led to the isolation of two novel quassinoid glycosides, named chuglycosides J and K, together with fourteen known lignans from the samara of A. altissima. The new structures were elucidated based on comprehensive spectra data analysis. All of the compounds were evaluated for their anti-tobacco mosaic virus activity, among which chuglycosides J and K exhibited inhibitory effects against the virus multiplication with half maximal inhibitory concentration (IC50) values of 56.21 ± 1.86 and 137.74 ± 3.57 μM, respectively.
