The 15th Conference on Ecology and Management of Alien Plant invasions is targeted to bring out the most modern technological developments and research on the management and ecology of plant invasions. The conference, thus, aims at forming future strategies for all the environmental issues of the world. The 15th conference discussed the major topics like invasive plants population dynamics, invasion success, bioinformatics, genetic characteristics, adaptive strategies in plant invasion, the effect of anthropogenic factors, control, and detection systems, soil, and climate on the invasion of plants, landscape structure, etc. There were oral communications, keynote lectures, symposia, and poster sessions. Apart from academic activities, there were commercial exhibitions, awards, and social programs.

Here are some of the key topics discussed at the conference.

  • Dissecting the success and impact of urban invasions

The urban invasion proves sensitive for some species while for others, it is offering big opportunities. Studies show that non‐indigenous species (NIS) benefit from urban invasion as they are capable of getting higher prosperity and more diversity in habitats of more urbanized behavior. They will then spread the impact to the native habitats. It is very important to study their functional traits to understand the ways they spread and impact the native habitats.

  • Unraveling context-dependency in invasion science 

The context of the invasion is very important as it determines when and where the invaders succeed and fail. It also helps to find out the systems that are more vulnerable to the invaders, the issues the invaders can cause, and the ways to handle them. Unraveling context-dependency is considered to be a very big challenge when it comes to invasion science.

What is Ecology? - Types, Importance And Examples Of Ecology
  • The big picture: a macroecological perspective on the global state of plant invasions

Biological invasions are one of the essential factors of global environmental change. But there is no accurate answer to the global factors that determine the invasion variations that are still to be found out. The future trajectories and consequences of biological invasions are also under a shadow. The advancement in data coverage, its availability, along with the tools that help in data integration can help in creating a comprehensive database of all the alien species distributions in the world.

  • The role of habitats in plant invasions: combining the source‐area and invaded‐area approaches

There is a specific habitat for every plant species where they get adapted to the abiotic environment. When a new species is introduced, there are chances that it will grow and spread abundantly in the regions that feel similar to its native habitat. Studies show that while some areas are rarely invaded by alien species, some other areas are frequently and heavily invaded.

  • Does the weed risk assessment predict timing rather than the probability of invasion?

Studies say that with the use of the trait‐based weed risk assessment (WRA) tools, those species that were predicted to experience lesser invasions can become invasive if they get more time in the range in which they are introduced. The findings from WRA were questioned in the conference and concluded it to be the case with a rapid invasion when compared to the slower ones in their transition from natural to a more invasive nature.
