NAIROBI (Xinhua) -- Scientists from a global invasive species organization on Friday warned a parasitic invasive weed known as Cuscuta is threatening the survival of crops and biodiversity in weste

A new research shows that invasive alien plant species introduced as ornamental plants at tourism facilities are spreading rapidly throughout the Serengeti-Mara ecosystem, posing a major threat to

The Asian tiger mosquito (Aedes albopictus) is an invasive species and important arbovirus vector that was introduced into the U.S. in the 1980's where it continues to expand its range. Winter temperature is an important constraint to its northward expansion, with potential range limits located between the 0° and -5°C mean cold month isotherm. Connecticut is located within this climatic zone and therefore, Ae. albopictus was monitored statewide to assess its northern range expansion and to delineate where populations can stably persist.

The spread of pests and pathogens that damage plant life could cost global agriculture $540 billion a year, according to this report released by the Royal Botanic Gardens in London. An increase in international trade and travel had left flora facing rising threats from invasive pests and pathogens, and called for greater biosecurity measures.

Wetlands seem to be more vulnerable to invasions compared to terrestrial ecosystems. The alien invasive weed, Ludwigia peruviana, invading the wetlands of the Dhansiri catchment and eastern part of Kopili in Assam has threatened the resident biodiversity and has also posed possibilities of spreading to other wetlands of North East India. The present study was conducted to measure the impact of the weed on the biodiversity of this region, to find out the causes for increasing invasiveness and to suggest a suitable management strategy.

New research by CABI reveals that just five invasive alien species are causing US$0.9 – 1.1 billion in economic losses to smallholder farmers across six eastern African countries each year, equatin

Scientists are calling for urgent action to halt the spread of a pest that is destroying maize crops is spreading rapidly across Africa.

Alien species are a major component of human-induced environmental change. Variation in the numbers of alien species found in different areas is likely to depend on a combination of anthropogenic and environmental factors, with anthropogenic factors affecting the number of species introduced to new locations, and when, and environmental factors influencing how many species are able to persist there. However, global spatial and temporal variation in the drivers of alien introduction and species richness remain poorly understood.

Present paper summarizes the occurrence of C. riisei in coral reefs of Indian seas, its likely impacts on the indigenous biota and policies for bioinvasion in the Indian context. With the limited information available on marine bioinvasion in tropical countries, especially in India, there is an urgent need of study on the occurrence and impacts of invasive species on the coral reef environment as this ecosystem harbors 25% of total marine biodiversity and contribute 10% fishery production.

Global wildlife could plunge to a 67 per cent level of decline in just the fifty-year period ending this decade as a result of human activities, according to WWF’s Living Planet Report 2016.
