    Invasion, spread and establishment of invasive alien species in a new environment causes serious ecosystem perturbation and native species extinctions. The problem is further aggravated under climate change as some invasive alien species perform better under elevated temperature and carbon dioxide regimes. Currently unsuitable regions such as high-altitude areas and mountains are likely to become more suited to invasion under future climatic conditions. We have modelled the distribution of one of the most invasive alien species, parthenium weed (Parthenium hysterophorus L.) which is rapidly colonizing different parts of Bhutan. The study was implemented in R environment using BIOMOD2 package; an ensemble modelling platform for species distribution modelling. Under current climate scenario, about 2.83% (1,099.01 km2) of the country’s total area was predicted t.. Read More»
