Special Issue Information
Dear Colleagues
Interactions between food web components in freshwater ecosystems are very complex. These organisms are associated with specific trophic groups (producers, herbivores, carnivores, detritivores, and omnivores). In general, there are two theories regulating the mechanisms that control the abundance and diversity within these groups, bottom-up and top-down, which predict influences of consumers and resource availability. All these effects are under the pressure of climate change. Climate change, seen as an increase in temperature, is likely to affect the metabolism of individuals and communities, which may lead to changes in community structure, species distribution, interspecific relations, and biodiversity. Freshwaters are particularly vulnerable to climate change, because these habitats are exposed to numerous anthropogenic stressors and are fragmented within a terrestrial landscape that limits the dispersion of many species as the environment changes. This Special Issue invites fundamental and experimental studies on habitat and diet utilization, niche dynamics, feeding strategy, and food webs, as well research on responses of freshwater organisms to the effects of rising temperature.

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.
