Dear Colleagues,

Climate change is one of the most severe threats to global lake ecosystems, affecting the chemical and physical parameters of lakes as well as their biotic communities, with consequences for ecosystem functioning. Many studies have highlighted that lakes may be valid sentinels for current climate change. Indeed, lakes integrate responses over time and are distributed worldwide, therefore acting as sentinels in many different geographic and climatic regions. The efficacy of lakes as sentinels depends on our understanding of internal lake processes and on our ability to discriminate signal from noise. The availability of long-term datasets and the spread of technology that allows for the collection of high-frequency data in lakes helps to disentangle these processes, thus furthering our comprehension of ecosystem functions in lakes. However, further studies are still needed to understand the threshold above which lake disturbance can trigger effects that may become difficult or impossible to reverse.

In this volume, we aim at collecting contributions investigating the responses of lakes to climatic changes analyzed through single limnological proxies (biotic and abiotic) and/or the combination of multiple parameters, deriving from both modeling studies and in situ investigation in order to highlight the role of lakes as sentinels and integrators of climate change.

Given your great expertise in the field, we are inviting you to contribute to this volume with an original article.

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. Water is an international peer-reviewed open access semimonthly 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 2600 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.
