Special Issue Information

Dear Colleagues,

We are pleased to announce a forthcoming Special Issue of Diversity focused on zooplankton, a key group in the aquatic ecosystems since they are a link between primary producers and secondary consumers. Everything about these organisms is fascinating, from their beauty to their complex life cycles and ecology.

Zooplankton occur around the world, from the Artic to the tropics, inhabiting all kinds of environments, such as small vernal pools, hypersaline lakes and, of course, the vast ocean. Where there is water, even if it is very little, it is possible to find zooplankton. Their colonization capacity is such that we can find them in small humid habitats, such as leaf litter, holes in trees and sphagnum mats. They are everywhere, in groundwater, hot springs, caves; they can even travel throughout time, thanks to their resting structures capable of remaining dormant for decades and centuries. Given the great diversity of environments to which they have adapted, it is easy to imagine that the number of zooplankton species in the world is huge, beyond measure even.

As would be expected in the current context of global climate change, the threats to these organisms are multiple and synergistic: the warming and acidification of the waters; eutrophication; contamination by pesticides, drugs, plastics, etc.; biological invasions; the destruction of wetlands; all these threats are endangering one of the key components of the aquatic food webs. Therefore, improving the scientific knowledge surrounding these organisms is more necessary than ever. This Special Issue has been created with that objective in mind.

Diversity’s team and we kindly invite you to submit a manuscript focused on any aspect of diversity, ecology and conservation of zooplankton, from specific case studies to reviews. All levels of organization are welcome, that is, species autoecology, population dynamics and community studies. Likewise, manuscripts dealing with both marine and freshwater species are welcome. If you are interested in this opportunity or have any questions, please do not hesitate to contact us.

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 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.

The seasonal fluctuations of the copepod Eodiaptomus japonicus, which dominates the zooplankton community of Lake Biwa, have been disrupted several times over the past 45 years. The aim of this study was to clarify the primary environmental factor that caused the disrupted seasonal cycle in population density of E. japonicus. Here, we tested the hypothesis that the disruption in their seasonal cycle was due to the impacts of water temperature, food conditions, and predator pressure, using an individual-based model (IBM). Based on the experimental data from the literature, we described the growth and reproduction of E. japonicus using temperature- and food-dependent functions. Previously, the developmental time of this species was expressed using Bělehrádek’s equation. In this study, we applied the Kontodimas equation, which successfully reproduced the effects of food scarcity at higher temperatures. Additionally, the influence of predators was incorporated into the survival rate of adult individuals. The long-term data set of Lake Biwa was input into the developed model to simulate the population fluctuations during the disruption period (1975–1979) and stable period (1995–1999) of their seasonal cycle. The combination of environmental data to be input was (1) water temperature, food availability, and predators; (2) water temperature and food availability; and (3) water temperature and predators. Disruptions in the seasonal cycle of the population were only observed in scenario (1) during the disruption period simulation, suggesting that the disrupted seasonal cycle of this species in Lake Biwa may have been caused by the effects of both food condition and predators. The results of simulation scenarios (2) and (3) indicated that predators have a stronger impact on the population than food availability. This time, we used common and simple indicators to describe food conditions and predators, but the model can be improved to be more complex and accurate as more data become available. Such models are important tools for understanding the relationship between environmental factors and the dynamics of diaptomid copepod populations. Full article
