This book offers a comprehensive, unique and up-to-date exploration of diatom ecology spanning from fundamental molecular aspects to the intricate dynamics of metacommunities.
In recent years there has been a considerable increase in the amount of research devoted to diatom ecology, with a wide spectrum of approaches. This large amount of information, published in many different journals and books, makes it very difficult to keep up to date, both for the trained researcher and for students. Eduardo A. Morales (d. May 2023) had the original idea to assemble chapters on various subjects within diatom ecology. The questions he posed to potential contributors framed the current book consisting of 12 chapters.
- Are diatoms suitable tools for ecological restoration?
- What would be the features that make them reliable in this context?
- What makes diatoms ecologically successful?
- In an ecological sense, why is there such variability in diatom reproductive strategies and why are they worth considering?
- What do new approaches in ecological synthesis provide to diatom ecology, biogeography and metacommunities?
- Are all diatoms widely spread and each species uniquely characterized by its own, unaltered phenotype?
- Can we really make any ecological consideration without knowing (with a high degree of certainty) the identity of taxa?
- Are urban ecosystems important repositories of biodiversity?
- What are the benefits and the progress in diatom ecology made by the diatom guild perspective?
- Why, how and when are soil diatoms used in bioindication and what are the benefits of such an approach?
- Are diatoms bona fide indicators of climate change?
- Are diatom communities in temporary rivers important for these lotic ecosystems as they are subjected to the effects of climate change?
- Do diatoms in peatlands behave differently from their terrestrial and aquatic (rivers, lakes, others) counterparts?
Audience
The book is intended primarily for professionals in the fields of diatom research, algal research (phycology), organismal, population and community ecology, limnology, microbiology, organismal biology, paleoecology and paleolimnology. The book will also serve as a reference for graduate students seeking guidance on terminology, techniques, and current methods in diatom research.

Diatoms: Biology and Applications
Series Editors: Richard Gordon and Joseph Seckbach
There are about 100,000 species and as many papers written about them since their discovery over three hundred years ago. The literature on diatoms shows about 60,000 papers during the period 2006-2023. In this context, it is timely to review the progress to date, highlight cutting-edge discoveries, and discuss exciting future perspectives. To fulfill this objective, this Diatom Series has been launched under the leadership of two experts in diatoms and related disciplines. The aim is to provide a comprehensive and reliable source of information on diatom biology and applications and enhance interdisciplinary collaborations required to advance knowledge and applications of diatoms.

Dedicated to Eduardo A. Morales In Memoriam 1968-2023
Eduardo Antonio Morales Luizaga (November 20, 1968 – May 19, 2023) was a distinguished biologist and educator, born in Argentina and proudly holding Bolivian citizenship. His academic journey was characterized by an unwavering commitment to advancing the field of ecology and fostering knowledge both locally and internationally.
Eduardo’s educational achievements included a bachelor’s degree in Biology from the University Mayor de San Simón in 1993. Seeking global perspectives, he pursued higher education in the United States, earning a Master of Science in Ecology from the University of Connecticut in 1997 and a PhD in Ecology in 2000. Eduardo’s dedication to learning was further demonstrated by his Diplomat in Higher Education from the Universidad Católica Boliviana in 2008.
Throughout his career, Eduardo held various positions that showcased his expertise and passion for ecology. He served as a lecturer at the Universidad Católica Boliviana, Cochabamba, Bolivia, and took on the role of curator at the Cryptogamic Herbarium within the same institution. Additionally, he contributed significantly as an associate researcher at the Phycology Section of the Patrick Center for Environmental Research, Academy of Natural Sciences of Drexel University in Philadelphia, Pennsylvania, USA.
Eduardo’s commitment to international collaboration was evident in his participation in numerous graduate courses and workshops spanning several countries. Notable among these were workshops on taxonomy, limnology, freshwater phytoplankton, and the harmonization of algal taxonomy in the United States and Latin America.
With a wealth of experience, Eduardo held key roles in academia and research. He played a pivotal part in the National Water Quality Assessment Program, serving as the taxonomy coordinator and analyst. As a research scientist at the Diatom Laboratory in the Phycology Section, Patrick Center for Environmental Research, he led workshops and contributed significantly to projects on river and lake diatoms in the continental United States.
Eduardo’s dedication to education extended beyond borders. He served as an invited lecturer and associate researcher in Bolivia, impacting the scientific community and inspiring future generations. His roles as a lecturer in various biology and ecology courses at the Universidad Católica Boliviana highlighted his commitment to knowledge dissemination.
In recognition of his contributions, Eduardo was an active member of several professional societies, including the Northeast Algal Society, Bolivian Limnological Society, Bolivian Scientific Society, Latin American and Caribbean Phycological Society, and Peruvian Phycological Society.
Eduardo received numerous honors, awards, and distinctions, such as the Fulbright Scholarship, Francis Rice Trainor Scholarship Award, and multiple staff education and development grants from the Academy of Natural Sciences of Philadelphia. His legacy continues through ongoing grants and research projects, where he focused on assessing diatom diversity in Bolivian cloud forests and studying algal biodiversity in various regions of Bolivia.
His impact on the scientific community, his commitment to education, and his contributions to environmental research leave an enduring legacy that will inspire future generations in Bolivia and beyond.

Preface
In recent years, there has been a considerable increase in the amount of research devoted to diatom ecology, with a wide spectrum of approaches. This large amount of information, published in many different journals and books, makes it very difficult for both trained researchers and students to keep up-to-date. Therefore, the idea of bringing together the most recent information on some of the topics related to diatom ecology was enthusiastically promoted by our dear colleague and friend, Eduardo A. Morales.
In order to carry out this project, Eduardo posed a series of questions on relevant topics in diatom ecology and, with these in mind, invited prestigious colleagues from different parts of the world to be part of this adventure, some as authors of chapters and others as reviewers of manuscripts.
The chapters finally included in this book attempt to answer some of the questions raised in the original proposal:
Are diatoms suitable tools for ecological restoration?
What would be the features that make them reliable in this context?
What makes diatoms (so) ecologically successful?
In an ecological sense, why is there such variability in diatom reproductive strategies and why are these worth considering?
What do new approaches in ecological synthesis provide to diatom ecology, biogeography and metacommunities?
Are all diatoms widely distributed and is each species uniquely characterized by its own, unaltered phenotype?
Can we really make any ecological consideration without knowing (with a high degree of certainty) the identity of taxa?
Are urban ecosystems important repositories of biodiversity?
What benefits have been realized due to the progress made in the ecological guilds of diatoms?
Why, how, and when are soil diatoms used in bioindication and what are the benefits of such an approach?
Are diatoms bona fide indicators of climate change?
Are diatom communities in temporary rivers important for these lotic ecosystems as they are subjected to the effects of climate change?
Do diatoms in peatlands behave differently from their terrestrial and aquatic (rivers, lakes, others) counterparts?
Eduardo died in May 2023, and we decided to complete the task and turn it into a tribute to his memory. We hope we have succeeded. For the colleagues (authors and reviewers) who helped us make this possible, we have nothing but words of thanks.

1Using Diatoms to Guide Successful Ecological Restoration
Evelyn E. Gaiser
Institute of Environment and Department of Biological Sciences, Florida International University, Miami, Florida, USA
Abstract
The number of aquatic ecosystems severely affected by human activities is rapidly increasing across the globe. Recognition of the extent of degradation of aquatic ecosystems and their services has catalyzed efforts to reverse these trends. To be successful, projects to restore or rehabilitate degraded aquatic ecosystems and their services require explicit achievable goals and regular assessments of progress toward those goals to guide adaptive management. Restoration targets are often established from knowledge of pre-disturbance or reference ecosystem states. Assessment monitoring can then include measurements of chemical and ecological criteria associated with that target. Diatoms have long been employed in assessing ecosystem degradation, particularly water quality deterioration, but there are fewer examples of their use in guiding the goals, assessment, and adaptive management of ecosystem restoration and resilience. This chapter evaluates whether diatoms provide an equally powerful tool for adaptively managing ecosystem restoration and resilience as they do for signaling ecosystem degradation. Examples of successful diatom-based restoration guidance are provided from the Florida Everglades, which is currently undergoing the largest-scale ecosystem restoration program in the world. The chapter also discusses novel approaches for building public literacy about diatoms to encourage more effective and widespread application in successfully rehabilitating and sustaining the planet’s threatened aquatic resources.
Keywords: Diatom indicators, ecological restoration, ecological resilience, Everglades restoration, adaptive management, ecosystem assessment
1.1 Introduction
Aquatic ecosystems are experiencing unprecedented degradation due to human activities, including climate change, widespread damming and diversion, agricultural development, urbanization, overfishing, introduction of non-native species, and pollution from chemicals, erosion, plastics, and solid waste [1.1]. Because of their ubiquity and sensitivity to environmental conditions, diatoms are frequently used to signal the effects of these human activities on aquatic ecosystems, including changes in pH, conductivity, transparency, hydrology, trophic state, oxygen, and nutrients, among other factors [1.2]. Diatoms are considered ecosystem engineers because they drive food webs, form soils, regulate biogeochemical cycles, and modify flow regimes. Because of their fast and reliable response to changes, diatoms also provide important indications of impending ecosystem-scale cascades [1.3]. Early detection and prevention of these cascades is important because they can lead to ecological state shifts that are difficult or almost impossible to reverse [1.4]. In recognition that state shifts often entail undesirable losses in aquatic ecosystem services, many countries have employed diatom-based water quality monitoring programs to identify degrading ecosystems. Targeting degrading ecosystems before they have reached these irreversible states is invaluable. Examples of diatom-based monitoring programs exist throughout North America [1.5] [1.6], Europe [1.7] [1.8] [1.9], and the tropics [1.10] [1.11] [1.12]. Diatoms and other organisms are sounding alarms that we are close to crossing planetary boundaries [1.13], warning of further degradation if widespread actions are not taken to reverse losses. However, comparatively little research has been conducted on (1) how efficiently these diatom signals are acted upon to limit degradation while ecosystems are still in a recoverable state, or (2) whether diatoms can serve as equally effective indicators of ecosystem recovery. This chapter reviews the literature related to these topics, addressing the question: what features make diatoms reliable indicators of ecological recovery, and how can we best use them to guide restoration and management of aquatic ecosystems for resilience in a rapidly changing world?
Determining whether and how diatoms can be used to guide more effective aquatic ecosystem management depends on how well they meet the needs of restoration managers. Those needs include: (1) reliable ecological condition targets based on pre-degradation, reference, and/or predicted (and achievable) desired conditions, (2) accurate indication of whether restoration actions are nearing or achieving target conditions, and also (3) clear and easily understood presentation of results to resource managers and the public, who finance and depend on the results [1.14]. This chapter addresses the key components of successful restoration programs and the desired features of diatom bioindicators that best help guide the restoration process.
While incorporation of diatoms into bioassessment of ecosystem recovery has received much less attention than their use in assessing risk of degradation [1.15], multiple studies have incorporated diatoms in establishing targets and assessing and communicating restoration progress. These studies include bioassessments of lakes, rivers, and wetlands undergoing restoration, which are often coupled with paleoecological, experimental, and modeling studies that have been used to establish targets and metrics. This chapter reviews these studies with a focus on the Florida Everglades, which is currently subject to the largest-scale global ecosystem restoration project ever attempted. The qualities of diatoms that best serve the needs of restoration managers are evaluated and then strategies are recommended for incorporating these qualities into restoration planning, assessments of ecosystem recovery and resilience, science communication, and engagement with the public.
1.2 Components of Successful Ecosystem Restoration
Ecological restoration is defined as an “intentional activity that initiates or accelerates the recovery of an ecosystem with respect to its health, integrity and sustainability” [1.16]. The process of restoring ecosystems typically entails phases of planning and design, implementation, monitoring and assessment, and evaluation to adaptively manage progress [1.17] [1.18]. The planning and design phase establishes objectives to scientifically evaluate the causes of degradation and propose actions necessary to reverse degradation to achieve desired ecosystem conditions [1.19]. Ideally, restoration plans are co-produced by scientists and stakeholders working together to generate targets that account for scientific and societal constraints and benefits [1.20] (Figure 1.1). Restoration targets are commonly based on biological conditions indicative of healthy ecosystem status, as determined from long-term data, historical knowledge, paleoecological information, or reference/undisturbed neighboring ecosystems. However, targets based on pre-disturbance baselines are not always achievable because most ecosystems are complex adaptive systems where more than one key driver is changing, including drivers that are irreversible at the scale of the restoration project [1.21]. For example, global climate change and non-native species introductions can continue to alter ecosystems even as local-scale drivers are being restored. In addition, most degraded ecosystems are so highly disturbed that they have lost critical features that are unrecoverable in realistic restoration timeframes, prompting use of more realistic terms like “rehabilitation” or “recovery” in the restoration science community [1.22
