Remote sensing and invasive species

A crucial step in evaluating the impact of invasive species is to map changes in their actual and potential distribution and relative abundance across wide regions over an appropriate time span. While direct and indirect remote sensing approaches have long been used to assess the invasion of plant species, the distribution of invasive animals is mainly based on indirect methods that rely on environmental proxies of conditions suitable for colonization by a particular species. The aim of this article is to review recent efforts in the predictive modelling of the spread of both plant and animal invasive species using remote sensing, and to stimulate debate on the potential use of remote sensing in biological invasion monitoring and forecasting.

GlobalChangeBiology in the Climate-ADAPT database

The European Climate Adaptation Platform (CLIMATE-ADAPT) aims to support Europe in adapting to climate change by providing easily searchable information about expected climate change in Europe, current and future vulnerability of regions and sectors, national and transnational adaptation strategies and actions, adaptation case studies and potential adaptation options, and tools that support adaptation planning. Information is stored in a database that contains quality checked information, including reference to the GlobalChangeBiology project.

GlobalChangeBiology project story published

A story about the GlobalChangeBiology project was published on the Horizon 2020 website in the Projects Stories section. The European Commission DG Research had commissioned an article on the GlobalChangeBiology project for publication on the DG Research website under “success stories”. After an interview by a professional writer, the article was prepared and eventually selected for publication on the official website of the European Commission.

Holistic approach in invasive species research

The Mediterranean Basin is a climate change and biological invasion hotspot where recent warming is facilitating the establishment and spread of invasive species, one of which is the highly destructive South American tomato leafminer (Tuta absoluta). This pest recently invaded the Mediterranean Basin where it threatens solanaceous crops. Holistic approaches are required to project the potential geographic distribution and relative abundance of invasive species and hence are pivotal to developing sound policy for their management. This need is increasing dramatically in the face of a surge in biological invasions and climate change. However, while holistic analyses of invasive species are often advocated, they are rarely implemented. We propose that physiologically-based demographic models (PBDMs) in the context of a geographic information system (GIS) can provide the appropriate level of synthesis required to capture the complex interactions basic to manage invasive species such as T. absoluta. We review the PBDMs for two invasive flies, and use them as a basis for assessing the biological data available for the development of a PBDM for T. absoluta, and in the process identify large data gaps that using the PBDM as a guide can be easily filled. Other components for an ecologically-based management program for this pest (habitat modification, natural and classical biocontrol, pheromones, and others) are also reviewed. The development of a PBDM for T. absoluta would provide the basis for an interdisciplinary agroecological synthesis of the problem and the role different control tactics would play in region-specific control of the pest.
