Trophic Interactions in Warm Freshwater Ecosystems

Dear Colleagues,

Trophic interactions are key for the structure and function of ecosystems, not least of which fresh waters. Most of the theoretical and empirical studies on trophic interactions and the consequences on ecosystem functioning, with applications to ecosystem restoration and rehabilitation, have been conducted in temperate climates, but increasing evidence suggests that, under warm climates, the strength of interactions and some cascading effects may differ. Ecosystems in warm climates are also more sensitive to anthropogenic impacts, such as eutrophication and water extraction, than similar ecosystems in temperate or cold climates, imposing different scenarios for the biota.

Consequences for the theoretical basis of restoration strategies are thus being critically reviewed. These pieces of evidence are also contributing to the prediction of effects to be expected with climate warming.

In this Special Issue, we welcome articles that describe trophic interactions in warm climate freshwater ecosystems (ponds, lakes, streams, rivers, lagoons, floodplains) that contribute to increase our basic and potentially applied knowledge on the particularities of these systems. We encourage comparative studies, manipulative experiments, long-term field studies, modelling and field experiments where clear hypotheses are tested.

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 250 words) can be sent to the Editorial Office for assessment.

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.
