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.

Long time series of ocean and land color satellite data can be used to measure Laurentian Great Lakes water quality parameters including chlorophyll, suspended minerals, harmful algal blooms (HABs), photic zone and primary productivity on weekly, monthly and annual observational intervals. The observed changes in these water quality parameters over time are a direct result of the introduction of invasive species such as the Dreissena mussels as well as anthropogenic forcing and climate change.

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.

The fall armyworm Spodoptera frugiperda is a prime noctuid pest of maize on the American continents where it has remained confined despite occasional interceptions by European quarantine services in recent years. The pest has currently become a new invasive species in West and Central Africa where outbreaks were recorded for

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.

Ancient woodland is under threat from invasive rhododendron, experts have warned as they revealed the “aggressive” weed now covers woodland the size of 150,000 football pitches.

The Protected Planet Report 2016 has been launched at the IUCN World Conservation Congress in Hawaii.
