An invasive Australian tree is now posing a serious threat to a global diversity ‘hotspot’ according to new collaborative research between Landcare Research in New Zealand, the Universities of Camb

Non-native plants invade some tropical forests but there are few long-term studies of these invasions, and the consequences for plant richness and diversity are unclear. Repeated measurements of permanent plots in tropical montane rain forests in the Blue and John Crow Mountains National Park in Jamaica over 24 to 40 years coincided with invasion by a non-native tree, Pittosporum undulatum.

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.

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.
