Special Issue Information
Dear Colleagues,
Alien species represent one of the most pressing issues in the field of invasion ecology due to their ecological impact on ecosystems as well as their economic consequences. New alien species are reported almost daily, and some of these can prove to be particularly invasive. Therefore, increased attention from both the scientific community and the general public is needed to address this issue.
In fact, the potential vulnerability of marine, terrestrial, and transitional habitats, the ecological and biological mechanisms that facilitate the establishment of non-native species, and the responses of native communities to such invasions constitute critical challenges in invasion ecology. Novel environments create novel opportunities, and phenotypic plasticity may provide a significant adaptive advantage in overcoming ecological barriers. Invasive species often represent a non-random subset of their source populations, and individual-level differences play a key role in their ecological and evolutionary trajectories. These traits are also central to determining the success and impact of biological invasions.
A macro-ecological approach can yield valuable insights into the dynamics between alien species and native biota, revealing patterns of spread, ecological interactions, and community responses. Comparative studies between invasive and phylogenetically related native species can help identify the functional traits associated with invasion success. Furthermore, when invaders and natives coexist sympatrically, fine-scale ecological investigations become possible, enabling high-resolution assessments of interaction outcomes.
In this view, it is essential to improve the management of alien species invasions, as well as the implementation of policies addressing this issue.
This Special Issue invites contributions that explore the alien species phenomenon from diverse perspectives. Topics of interest include—but are not limited to—species interactions, adaptive strategies, introduction and expansion pathways, community-level responses, and effects on ecosystem functioning and services.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Diversity is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
