Restoration ecology: the study of applied optimism

As a young trainee in the field of restoration ecology in the modern age, it is difficult to feel optimistic about our future. As many environmental protections are de‐regulated and the climate crisis heightens, I turned to restoration to find hope in a changing world. Restoration ecologists are the optimists of biology. We work every day to make the world a better place and our passion and forward thinking spurred the United Nation's “decade of restoration.” Learning about the successes of the hardworking members of this field gives me hope. As the earth moves toward an unimaginable future, we should continue to try to make the world a better place and encourage those around us to act and restore the environments they value, whether it be large‐scale restoration or preserving garden pollinator habitat. I am forever thankful to restoration ecology and the optimism the field provides.     

Pitch the niche – taking responsibility for the concepts we use in ecology and species distribution modelling

In a discussion it is often easier to staunchly reject or offer resolute support for an idea. This third paper on the niche concept aims to develop a balanced argument by exploring general principles for determining an appropriate level for pitching the niche concept that will guide better use and less abuse of niche concepts. To do this we first have to accept that niche concepts are not necessarily essential for ecology. Rather than to improve niche concepts, our aim should then be to pitch the niche in terms of ecology. This aim helps us develop an ‘ultimate goal of the niche’ by which we can evaluate the concepts we use. For species distribution modelling, there has been a focus on the niche as an equilibrium outcome that perhaps has less relevance for disequilibrium situations (e.g. climate change projections). As is the case for much of ecology, more causal explanations of species' distributions use alternative terminologies and less frequently use the word ‘niche’. We suggest that niche concepts that are better aligned with the rest of ecology could arise from taking more responsibility for our own implementations, and by explaining our models with terms other than niche. A general, holistic niche concept promotes this view and promotes practical thinking about what we are modelling and how we interpret those models, which in turn should help inspire and support innovative modelling approaches in species distribution modelling.     

蚯蚓环境生态作用研究进展

蚯蚓的环境生态作用有促进微生物和其它土壤动物活动、破碎和消化分解枯落物、提高土壤肥力及环境指示等方面.目前,国内蚯蚓环境生态作用研究侧重于污染生态系统,湿地和森林两大天然生态系统的相关研究较少.国外,20世纪70年代的研究主题与我国现状相似,80年代从蚯蚓生理生态、种群生态、群落生态、生态系统生态等多尺度展开研究,90年代以来向蚯蚓生态学微观尺度的分子生态、宏观尺度的景观生态拓展.今后,继续研究蚯蚓促进物质循环、治理污染、提高土壤肥力及蚯蚓与农业、与微生物的关系等热点问题的同时,还应利用新技术提高研究精度,注意室内外研究相结合及特殊蚓种的环境适应性比较与接种研究以提高研究成果的实用性.     

To the future: An ecology of love,hope, and action

This is an edited version of a keynote address given at the 2023 Ecological Society of Australia conference ( https://youtu.be/0JDJ9RdIkP4 ). I argue that the practice of ecology gifts us a unique capability to see and understand the beauty, intricacy and wonder of the natural world, but also powerful insight into biodiversity loss and its consequences. With such privilege we should take more responsibility for its protection. We should recognize that love drives our concern for nature and that emotion renders us more persuasive advocates. Despair at environmental loss is understandable but unhelpful, and we must find hope and build from it. Such hope comes, for example, from a sense of community connection to and concern for nature; in increasingly bold commitments by governments and many organizations to protect biodiversity; in the increased recognition and respect shown in Australia for First Nations management and perspectives on responsibility for country; and in those (albeit still too few) success stories of recovery.     

Reinterpreting Industrial Ecology

This article argues that industrial ecology has, to date, largely engaged with the ecological sciences at a superficial level, which has both attracted criticism of the field and limited its practical application for sustainable industrial development. On the basis of an analysis of the principle of succession, the role of waste, and the concept of diversity, the article highlights some of the key misconceptions that have resulted from the superficial engagement with the science of ecology. It is argued that industrial ecology should not be seen as a metaphor for industrial development; industrial ecology is the ecology of industry and should be studied as such. There are manifold general principles of ecology that underpin our understanding of the world; however, the physical manifestation and causal effects of these principles are particular to the system and its constituent elements under analysis. It is thus proposed that context‐specific observation and analysis of industry are required before theoretical and practical advancement of the field can be achieved.

Ecology after 100 years: Progress and pseudo-progress

Has the science of ecology fulfilled the promises made by the originators of ecological science at the start of the last century? What should ecology achieve? Have good policies for environmental management flowed out of ecological science? These important questions are rarely discussed by ecologists working on detailed studies of individual systems. Until we decide what we wish to achieve as ecologists we cannot define progress toward those goals. Ecologists desire to achieve an understanding of how the natural world operates, how humans have modified the natural world, and how to alleviate problems arising from human actions. Ecologists have made impressive gains over the past century in achieving these goals, but this progress has been uneven. Some sub-disciplines of ecology are well developed empirically and theoretically, while others languish for reasons that are not always clear. Fundamental problems can be lost to view as ecologists fiddle with unimportant pseudo-problems. Bandwagons develop and disappear with limited success in addressing problems. The public demands progress from all the sciences, and as time moves along and problems get worse, more rapid progress is demanded. The result for ecology has too often been poor, short-term science and poor management decisions. But since the science is rarely repeated and the management results may be a generation or two down the line, it is difficult for the public or for scientists to decide how good or bad the scientific advice has been. In ecology over the past 100 years we have made solid achievements in behavioural ecology, population dynamics, and ecological methods, we have made some progress in understanding community and ecosystem dynamics, but we have made less useful progress in developing theoretical ecology, landscape ecology, and natural resource management. The key to increasing progress is to adopt a systems approach with explicit hypotheses, theoretical models, and field experiments on a scale defined by the problem. With continuous feedback between problems, possible solutions, relevant theory and experimental data we can achieve our scientific goals.

Microbial functional diversity: From concepts to applications

Functional diversity is increasingly recognized by microbial ecologists as the essential link between biodiversity patterns and ecosystem functioning, determining the trophic relationships and interactions between microorganisms, their participation in biogeochemical cycles, and their responses to environmental changes. Consequently, its definition and quantification have practical and theoretical implications. In this opinion paper, we present a synthesis on the concept of microbial functional diversity from its definition to its application. Initially, we revisit to the original definition of functional diversity, highlighting two fundamental aspects, the ecological unit under study and the functional traits used to characterize it. Then, we discuss how the particularities of the microbial world disallow the direct application of the concepts and tools developed for macroorganisms. Next, we provide a synthesis of the literature on the types of ecological units and functional traits available in microbial functional ecology. We also provide a list of more than 400 traits covering a wide array of environmentally relevant functions. Lastly, we provide examples of the use of functional diversity in microbial systems based on the different units and traits discussed herein. It is our hope that this paper will stimulate discussions and help the growing field of microbial functional ecology to realize a potential that thus far has only been attained in macrobial ecology.     

Socioecologies

I chart ways in which ecology could improve its performance in assessing the humanity-nature relationship. The life of humans, similar lo all biological organisms, depends on utilization of their environment which is changed as a result. To evaluate the consequences, a broad range of issues needs to be addressed ranging from the historical dynamics of cultural development to specific idiosynchratic features of particular environmental issues. One should avoid nature-culture dualism both in theoretical thinking and practical research. A typical form of such dualism in ecologically informed environmentalism is an assumption that productivity of socio-economic systems vs natural systems is a zero-sum game: this assumption is unfounded. Ecology should take the ecological conditions of human existence seriously and make judgements on the relationship of people with their natural environment in various historical situations in a contextually sensitive way. I end by listing several types of positive contribution that ecology could give to societal discussion on the human environmental predicament; the most Important challenge is to point out new possibilities even in situations which seem hopeless.     

城市可持续发展能力的能值评价新指标

能值理论、方法克服了传统能量与经济分析方法的诸多缺憾,为城市可持续发展的研究提供了全新的视角。但作为一种新兴的理论,其评价指标,尤其是针对城市可持续发展能力的综合评价指标尚不完善。从生态经济效益及环境影响的全面表达角度,剖析了国际现行可持续发展能值指标(ESI)的不足之处,并在此基础上拓展构建了新的可持续发展能值指标(EISD)。以珠江三角洲中山市1996～2000年的发展动态为例进行了案例研究。结果表明,新拓展的可持续发展能值指标．在系统效益评价中考虑了系统能值产出的实际经济效果,在环境影响评价中同时考虑了系统的消耗影响和排放影响,可以更全面明晰的评价城市系统的可持续发展能力、状态及其成因,为系统的优化指明方向。     

Wild Animals in Our Backyard. A Contextual Approach to the Intrinsic Value of Animals

As a reflection on recent debates on the value of wild animals we examine the question of the intrinsic value of wild animals in both natural and man-made surroundings. We examine the concepts being wild and domesticated. In our approach we consider animals as dependent on their environment, whether it is a human or a natural environment. Stressing this dependence we argue that a distinction can be made between three different interpretations of a wild animal’s intrinsic value: a species-specific, a naturalistic, and an individualistic interpretation. According to the species-specific approach, the animal is primarily considered as a member of its species; according to the naturalistic interpretation, the animal is seen as dependent on the natural environment; and according to the individualistic approach, the animal is seen in terms of its relationship to humans. In our opinion, the species-specific interpretation, which is the current dominant view, should be supplemented—but not replaced by—naturalistic and individualistic interpretations, which focus attention on the relationship of the animal to the natural and human environments, respectively. Which of these three interpretations is the most suitable in a given case depends on the circumstances and the opportunity for the animal to grow and develop according to its nature and capabilities.

Microbial ecology in the age of genomics and metagenomics: concepts, tools, and recent advances

Microbial ecology examines the diversity and activity of micro-organisms in Earth's biosphere. In the last 20 years, the application of genomics tools have revolutionized microbial ecological studies and drastically expanded our view on the previously underappreciated microbial world. This review first introduces the basic concepts in microbial ecology and the main genomics methods that have been used to examine natural microbial populations and communities. In the ensuing three specific sections, the applications of the genomics in microbial ecological research are highlighted. The first describes the widespread application of multilocus sequence typing and representational difference analysis in studying genetic variation within microbial species. Such investigations have identified that migration, horizontal gene transfer and recombination are common in natural microbial populations and that microbial strains can be highly variable in genome size and gene content. The second section highlights and summarizes the use of four specific genomics methods (phylogenetic analysis of ribosomal RNA, DNA-DNA re-association kinetics, metagenomics, and micro-arrays) in analysing the diversity and potential activity of microbial populations and communities from a variety of terrestrial and aquatic environments. Such analyses have identified many unexpected phylogenetic lineages in viruses, bacteria, archaea, and microbial eukaryotes. Functional analyses of environmental DNA also revealed highly prevalent, but previously unknown, metabolic processes in natural microbial communities. In the third section, the ecological implications of sequenced microbial genomes are briefly discussed. Comparative analyses of prokaryotic genomic sequences suggest the importance of ecology in determining microbial genome size and gene content. The significant variability in genome size and gene content among strains and species of prokaryotes indicate the highly fluid nature of prokaryotic genomes, a result consistent with those from multilocus sequence typing and representational difference analyses. The integration of various levels of ecological analyses coupled to the application and further development of high throughput technologies are accelerating the pace of discovery in microbial ecology.     

Amazonian historical ecologies

Historical ecology may be defined as the undertaking of a diachronic analysis of living ecological systems, with the view to accounting more fully for their structural and functional properties. Historical ecology, more an approach or a research strategy than a paradigm, addresses a central question: 'How does environmental change relate to the historical development of human societies?' An integral part of the new ecological anthropology, historical ecology seeks to dereify the concepts of nature and culture, and to rethink critically the complexity of the biological world, particularly the problematic distinction between the wild and the domesticated, which has hitherto inspired natural science research on the diversity of biological life. This paper examines the ways in which historical ecology has been used to research nomadic bands subsisting with few or no domesticates in lowland South America. I argue that current knowledge of the Amazon biome, which is far more sophisticated than it was in the late 1940s and the early 1950s, when Steward edited the Handbook of South American Indians , allows us to rethink human occupation of, and adaptation to, the Amazon; to redefine the forces that have shaped the material dimensions of social life, and to recognize that Amazonian hunter-gatherers have played an active part in the making of the natural environment that they have occupied for millennia. I also argue that 'trekking', far from representing a necessary intermediary stage in the regression from horticulture to foraging, constitutes, in some cases, a sui generis solution to deep contradictory forces of a political, religious, and social character. Such internal processes may have long predated the Conquest and the disruptions it caused. I conclude that reliance on resources created in the past may be a characteristic shared by various trekking and foraging groups of the Upper Amazon.

Modem organic-walled dinoflagellate cysts in arctic marine environments and their (paleo-) environmental significance

The Arctic Ocean is one of the least known marine regions of the world. Because of its major influence on global climate and its hostile environmental conditions it is a fascinating area for paleoecological, paleoclimatic and paleoceanographic research. The composition of planktic microfossil assemblages, and both the trace-element and stable isotope compositions of hard parts, provide us with valuable information about the physical and biochemical parameters of surface waters in the high northern latitudes. Calcareous and biosiliceous microfossils that are traditionally used in Quaternary paleoenvironmental studies are of limited value in the Arctic Ocean because of their low abundances, low diversity and/or low preservation potential. The past several decades have seen considerable progress in our knowledge of the ecology and biogeography of dinoflagellates and their organic-walled cysts in the high northern latitudes, and these dinoflagellate cysts are now important proxies for reconstructing surface water conditions in the Quaternary. This arcticle gives an overview of the ecology of dinoflagellates and their cysts, the processes that transform the living communities into sediment communities, and the environmental gradients that may be reconstructed from fossil dinoflagellate cysts assemblages in the high northern latitudes.      

Marine Metagenome as A Resource for Novel Enzymes

More than 99% of identified prokaryotes, including many from the marine environment,cannot be cultured in the laboratory. This lack of capability restricts our knowledge of microbial genetics and community ecology. Metagenomics, the culture-independent cloning of environmental DNAs that are isolated directly from an environmental sample, has already provided a wealth of information about the uncultured microbial world. It has also facilitated the discovery of novel biocatalysts by allowing researchers to probe directly into a huge diversity of enzymes within natural microbial communities. Recent advances in these studies have led to a great interest in recruiting microbial enzymes for the development of environmentally-friendly industry. Although the metagenomics approach has many limitations, it is expected to provide not only scientific insights but also economic benefits, especially in industry. This review highlights the importance of metagenomics in mining microbial lipases, as an example, by using high-throughput techniques. In addition, we discuss challenges in the metagenomics as an important part of bioinformatics analysis in big data.     

Resource-allocation rules and the heritability of traits

I hypothesize that the heritability of a trait, and thus its evolutionary responsiveness to natural selection, should be positively related to the priority with which resources are allocated to that trait. Low-priority traits are more sensitive to environmental effects, thus reducing the relative effect of genetic differences on phenotypic variation of these traits. This allocation-priority hypothesis explains why life-history traits, such as those involving growth and reproduction, generally have lower heritabilities than higher-priority morphological and physiological traits related to body maintenance. This hypothesis also shows how an organism-centered approach, as used in physiological ecology, can contribute to the development of evolutionary theory.
