Mikania micrantha is one of the major invasive alien plant species in tropical moist forest regions of Asia including Nepal. Recently, this weed is spreading at an alarming rate in Chitwan National Pa...
A theory that uses the mathematics of a drunken walk describes ecological invasions better than waves, according to Tim Reluga, associate professor of mathematics and biology, Penn State.The ability t...
Almost all remote sensing studies model invasion of species dominating ecosystems canopies, typically in predicting their presence or absence. However, a vast majority of invasive species do not domi...
Rap1a and Rap1b are two closely related members of the Ras family of small GTPases. Despite their high sequence similarity, the two proteins serve non-redundant functions in cells and organs. Rap1a pl...

A myriad of medicinal effects has been attributed to Thymoquinone (TQ), the major biological-active component of Nigella sativa. TQ has been shown to exhibit potent anti-tumor activities. The present ...
The nuisance alga Gonyostomum semen (Raphidophyceae) has expanded in the Nordic countries during the last decades and can dominate lake phytoplankton communities almost completely. A possible explanat...
We conducted a 3-yr study of the population dynamics of the invasive cladoceran Bythotrephes longimanus in Island Lake Reservoir (Minnesota) and compared our results to other human-constructed reserv...
