Does travel stress strengthen invasiveness?

boats-cargo-cargo-container-753331

Research has already shown that invasive species tend to be more tolerant to environmental stress than related non-invasive species. However, a recent study published in Biological Invasions, set out to discover whether this stress tolerance was an inherent trait or whether it was something acquired en route from their natural habitat to the new one.

Invasive Alien Plants

The CABI Blog

By Carol Ellison

It was back in the early 1990s, on my first field trip to Assam in North-east India, with invasion ecologist Dr. Sean T. Murphy, when I first encountered mikania growing as an invasive weed. Until then, I had only seen this vine in its Central and South American native range, where locating a population of the plant could sometimes take all day.

Fostering partnerships to combat fall armyworm

IMG_0155

Since 2017, CABI has been heavily involved in the international effort to develop and implement a continental framework for tackling fall armyworm in Africa. Initial meetings resulted in the development of a draft framework, which identified roles for different organisations involved in fall armyworm management globally and on the African continent, including CABI. This has culminated into what has officially become known as the Framework for Partnership for Sustainable Management of the Fall Armyworm in Africa.

Invasive species in rubbish dumps: A new challenge for waste management practices?

By Dr Pablo L. Plaza, Dr Karina L. Speziale, and Dr Sergio A. Lambertucci

In the current global climate of excess waste production around the world, there is great concern about how waste and dump sites could be a global problem, especially because the amount of global waste is only set to increase in the near future. At the moment, 3 million tonnes of waste is discarded around the world every day and by 2025, that total is expected to double.

Air pollution and contamination of water corps and soil with a range of toxins are common problems associated with the management of dump sites. Added to this is the presence of infectious pathogens in these sites, which can cause disease outbreaks for the communities living near to a rubbish dump site and even those in more distant areas.

Plans towards developing a comprehensive strategy that will enable sub-Saharan Africa (SSA) to deal more proactively and effectively with invasive species have advanced significantly.

This milestone has been achieved through a recently concluded workshop co-organised by the International Centre of Insect Physiology and Ecology (icipe), the International Institute of Tropical Agriculture (IITA) and CABI, with support from the Swiss Development Cooperation (SDC).

Could invasive plant management prevent the spread of malaria?

Mosquito - blog banner

CABI scientists have joined an international team of experts who suggest that the large-scale management of a range of some invasive plants could hold the key to reducing the spread of deadly malaria.

Dr Arne Witt and Dr Sean Murphy worked with scientists from the University of Illinois, The Ohio State University and the Fundación para el Estudio de Especies Invasivas (FuEDEI) in Argentina, to conduct a review of existing studies which looked at how mosquitoes are attracted to both land and water-based invasive plants such as water hyacinth, floating pennywort and prosopis and how best these invasive plants can be managed.

The Valentine’s Day Invasion

Rose Bouquet

The influx of imported flowers in time for Valentine’s Day increases the risk of invasive pests making their way into native vegetation. Throughout January and February each year, customs and border agents have to inspect floods of bouquets arriving from across the globe to their intended markets in the US and Europe. While the pretty petals are intended to impress loved ones, they could also be carrying unwanted guests.
