An unknown Vincetoxicum species has recently been discovered in eastern Thailand. It is a twiner that resembles its morphology flexuosum s.l., variable taxon widely occurring from tropical Asia to Australia. Morphological examination showed despite similarities growth habit, leaf shape, gross appearance of inflorescence structure and flower colour, these two elements exhibit substantial differe...

Invasive plants are an increasing threat to global biodiversity. Effective management depends on accurate predictions of their spread. However, modelling the geographic distribution invasive species, particularly with correlative species models (SDMs), is challenging. SDMs assume that in equilibrium environment (i.e. they occur all suitable environments); this assumption likely be violated for ...

To explore the biosystematics of the Calligonum mongolicum complex (Polygonaceae), the flowering phenological period, breeding and pollination characters and seed set of the complex (Calligonum Mongolicum Turze, Calligonum chinense A. Los., Calligonum gobicum A. Los., Calligonum pumilum A. Los. and Calligonum zaidamense A. Los.) were documented in the Turpan Eremophyte Botanical Garden, China. ...

The evolution of ecomorphs within a species may represent either unique evolutionary events or multiple convergent events in similar environments. Functional studies of differing morphological traits of ecomorphs have been important to elucidate their role in adaptive radiations. The Cape dwarf chameleon, Bradypodion pumilum, has two ecomorphs: a large, brightly colored, ornate form found in cl...

The ability of arbuscular mycorrhizal fungi (AMF) to influence the performance of nonnative invasive plants in their introduced range has received increasing attention. The dependence of the invasive nonnative vine pale swallow-wort on AMF was studied in three greenhouse experiments. The aims of the present work were to (1) determine AMF colonization levels of field-collected pale swallow-wort ...

Fragmented landscapes may have implications for the genetic structure of populations and microevolution plant species. In particular, landscape fragmentation and/or population isolation might affect evolution mating systems. Here, we study consequences on a perennial herb, Vincetoxicum hirundinaria with mixed system. Our area, south-western Finnish archipelago, was formed after glacial ice shee...
