A systematic map protocol Claes Bernes 1 , James M.

Abstract Background In many parts of the world, roadsides are regularly managed for traffic-safety reasons. Methods The proposed systematic map is intended to provide an overview of the available evidence on how biodiversity is affected by various forms of roadside management, and how such management influences the dispersal of species along roads or roadsides. Background Roadsides as habitats and dispersal corridors The creation of road networks has been a critical component of the development of our civilisation.

Roadside management The occurrence of animals and plants along roads is highly dependent on how the roadsides are managed [ 4 ].

Topic identification, scientific basis and stakeholder input The topic of the proposed systematic map was suggested by the Swedish Board of Agriculture at a meeting with stakeholders arranged by the Mistra Council for Evidence-Based Environmental Management EviEM in Objectives The proposed systematic map is intended to provide an overview of the available evidence on how biodiversity is affected by various forms of roadside management, and how such management influences the dispersal of species along roads or roadsides.

Primary question How are biodiversity and dispersal of species affected by the management of roadsides? Components of the primary question Population : Roadside habitats and the species found within them. Methods Search terms The review team has conducted a scoping exercise to assess alternative search strings, testing them against a set of some 20 articles known to be relevant. No time, language or document type restrictions will be applied.

Publication databases The search aims to include the following online databases: 1. Academic Search Premier. Biological Abstracts. Helda University of Helsinki. Web of Science.

Wiley Online Library. Search engines Internet searches will be performed using the following search engines: Google www. Google Scholar scholar. In each case, the first hits based on relevance will be examined for appropriate data. Specialist websites Websites of the specialist organisations listed below will be searched for links or references to relevant publications and data, including grey literature.

Environment Canada www. European Environment Agency www. Infra Eco Network Europe www. International Union for Conservation of Nature www.

Natural Resources Canada www. Nordic Council of Ministers www. Norwegian Institute for Nature Research www. Swedish Transport Administration www. Swedish University of Agricultural Sciences www. UK Centre for Ecology and Hydrology www. United Nations Environment Programme www. United States Environmental Protection Agency www. Other literature searches As a check of the comprehensiveness of our searches, relevant articles and reports will also be searched for in bibliographies of literature reviews.

Screening of articles When screening a sample of articles found in Web of Science with the search string above, we noted that only about a third of the articles could safely be excluded as irrelevant based on their titles alone. Study inclusion criteria Each study must pass each of the following criteria in order to be included.

Relevant type of comparator Non-intervention or alternative forms of roadside management. Relevant types of outcome: i Measures of local or regional biodiversity, e. All species of animals, plants and fungi will be included. Relevant type of study Primary field studies. Systematic map output The final report will describe the review process and the evidence base, identifying possible knowledge gaps i.

The report will be accompanied by a database with the following kinds of metadata on each study that is included in the systematic map: Full citation. Language of article. Country where the study was conducted. Road type. Adjacent land use. Type of intervention. Type of outcome. Species or species group s studied. References 1. Google Scholar 2. Google Scholar 3.

The seeds of attractive plants native to areas outside North America are routinely used in gardens and have the capacity to disperse to wild areas if conditions are suitable e. Also, bighead and silver carp originating from China were introduced to catfish farm ponds in the United States to control algal growth. Fish accidentally escaped from these ponds and have subsequently colonized the Mississippi, Missouri, Illinois and Ohio rivers where they have had significant negative impact on the native fauna Figure 6.

Dispersal is a common process undertaken by individuals at different stages of the life cycle and in response to various factors. Morphological adaptations make dispersal achievable but with varying degrees of success due to anthropogenic and natural barriers. These barriers modify the level of dispersal and consequently exert effects on population dynamics and genetic structure. As environments are altered, through stochastic events and global climate change, it will become increasingly important to assess how such changes will affect dispersal at the individual, population, and species levels.
