Abstract Invasive alien plants (IAPs) are a significant threat to the biodiversity and ecological functioning of sub-Antarctic Prince Edward Islands (PEIs); however, weed biological control has not yet been implemented as management tool. The PEIs have had 23 recorded, which several considered beyond eradication therefore could benefit from release safe effective biocontrol agents. We used Sout...

Megaphyllum sensu stricto, i.e. the nominotypical subgenus of the very complicated genus Megaphyllum Verhoeff, 1894, is redefined on the basis of examination of type and non-type material and literature data. Four species-groups including twenty species in all are listed, and the identity of M. austriacum (C. L. Koch, 1838) is clarified with a proposal of neotype designation under ICZN Article ...

The methanolic extract of the whole plant of Echium glomeratum Poir. (Boraginaceae) has afforded five pyrrolizidine alkaloids, three that were (7S, 8R)-petranine (1), (7S, 8S)-petranine (2), and (7R, 8R)-petranine (3a) or (7R, 8S)-petranine (3b), comprising a tricyclic pyrrolizidine alkaloids subclass; and two that were known but to the species: 7-angeloylretronecine (4) and 9-angeloylretroneci...

What kinds of intuitions do people have for solving problems in a formal logic system? Studies on intuitive physics have shown that people hold a set of naive beliefs Caramazza, and Green (1980) found that when people were asked to draw the path of a moving object shot through a curved tube, they believed that the object would move along a curved (instead of a straight) path even in the absence...

Antimicrobial resistance is a subject of great concern in public health and also in the designing of strategies for current therapeutic protocols all over the world. New drugs, including those necessary for a reserve armamentarium and exhibiting less side effects deserve special attention. In rural areas, particularly in Brazil, a huge number of natural products, in different artisanal preparat...

Aim The Balkan Peninsula has served as source for the colonisation of large parts Europe after Pleistocene, but processes driving intraspecific diversification within are much less understood. To fill this gap, we investigated phylogeography and evolutionary history three habitat-segregated Cerastium taxa endemic to Dinaric Alps explored whether they responded differently Quaternary climatic os...

The role of seabirds as sea-land biovectors of nutrients is well documented. However, no studies have examined whether and how colonial seabirds that differ in diet may influence terrestrial vegetation. Therefore, the purpose of the study was to describe and compare plant communities located in the vicinity of the two most common types of seabird colonies in Arctic, occupied by piscivorous or p...
