As part of a project aiming to determine the lichenised fungal biodiversity of James Ross Island (Eastern coast of Antarctic Peninsula), we identified three infrageneric taxa which were previously not reported from Antarctica: Farnoldia micropsis (A. Massal.) Hertel, Gyalolechia epiphyta (Lynge) Vondrák and Placidium squamulosum var. argentinum (Räsänen) Breuss. Detailed morphological and anatomical properties of these species along with photographs based on the Antarctic specimens are provided here. In addition, the nrITS, mtSSU and/or RPB1 gene regions of the selected specimens are studied and the phylogenetic positions of the species are discussed. The DNA sequence data for Farnoldia micropsis are provided for the first time. Farnoldia micropsis and Gyalolechia epiphyta are also new to the Southern Hemisphere.
The diversity and distribution of wild bees are dramatically changing due to habitat fragmentation, agricultural intensification and climate change. In cities, urban gardens are proposed ‘island’ habitats for bees offering floral and nesting resources. Yet, it is largely unclear how gardens play a role in changes in species diversity and distribution. This paper reports on the discovery of a bee species to our knowledge previously undocumented in the region of Berlin, Germany. We discovered Lasioglossum limbellum in a community garden created on concrete slabs of annual and perennial vegetation. As a cavity nester in soft rock cliffs—a natural habitat functionally not existent in urban areas—the life history of this species makes this discovery particularly interesting, and an opportunity to explore the role of urban gardens in biodiversity change. This report aims to spur future research, reporting and discussion on the changes in diversity and distribution of wild bees specifically in urban areas.
The epiphytic lichen species richness and community composition was compared for 600 living trees distributed within the interior of 60 Scots pine and Norway spruce monoculture stands in southern Sweden. A higher species richness, and more unique species, was found on trees of Scots pine than of Norway spruce, and distinctive communities were associated with the two tree species. Lichen species composition also shifted between the 30-, 55- and 80-year-old stands, although there was no significant difference in species richness between the different age classes. Tree species and age of the stand explained most of the variation in community composition (41%), with additional variance explained by lichen proximity to the ground (6%) and aspect (1%) (northern/southern side of trunk). Scots pine and Norway spruce share many attributes, such as both being conifers with acidic bark properties and having a similar geographical distribution in Fennoscandia. However, our study showed that species richness and community composition can nevertheless diverge in stands dominated by these two tree species. Since the occurrence of red-listed species was low in these stands, we suggest that 80-year rotations are not long enough for the occurrence of the many rare and specialized lichen species that require old forest structures and long forest continuity in this region.
Global aspects of biodiversity loss are widespread. Tropical habitats in Africa, South America and South-East Asia have been decimated by deforestation and encroachment by increasing numbers of people. International organisations including the United Nations (UN) have considered population issues, but the list of sustainable goals propounded by the UN makes no more than peripheral mentions of population pressures. There have been international conferences on major environmental issues including climate change and biodiversity declines, but again with few mentions of the impact of the human population. However, there has been a series of international meetings concerned with population growth. Unfortunately, these have proved disappointing, frequently sidetracked into areas that have not resulted in any consensus on the development of population policies.
The introduction seeks to set the research questions to be explored throughout the book: what is the nature of the human relationship with nature, what are the central ideologies and assumptions that inform the management of the human–wildlife relationship, how are these ideologies reflected in law and legal institutions and, finally, how do they need to be changed. It outlines the approach the book will take in order to answer these fundamental questions.
The conclusions reached in Chapter 8 centre on the formulation of liberal autonomy in our wildlife laws and policies. Throughout the book it was demonstrated that autonomy has been created and maintained by a dominant neo-liberal and capitalist paradigm because it serves and furthers that paradigm. This relationship between autonomy and neo-liberalism creates a hierarchy that serves western notions of power and control. The law is a tool that has been used to this end. Further, these themes dictate our relationship with wildlife because the law as an institution creates and maintains these themes in wildlife governance. Instead, the research suggests that we need a broader and more inclusive view of the relationship, which extends outside of the dominant paradigm. The conclusions foreground a possible move away from the promotion of autonomy as the basis of our laws and policies and a move towards a response to vulnerability that builds resilience. This can be achieved with further focus on inclusive collaborative governance, traditional ecological knowledge, compassion, emotion and other forms of knowledge and an acknowledgement of the intrinsic value of wildlife and the environment as a whole.
As a result of increasing global demand for food, large areas of natural habitat are being converted to agroecosystems to accommodate crop cultivation. This agricultural expansion is most prominent in the tropics, where many rural communities are dependent solely on farming income for their livelihoods. Such agricultural land conversion can have severe implications for local fauna. In this study, we compared vertebrate species diversity between natural forest habitat and three types of vanilla plantations maintained under varying management regimes in north-east Madagascar. We used diurnal and nocturnal transects to survey vertebrate diversity. Natural forest habitat contained the greatest vertebrate species diversity, and had proportionally more threatened and endemic species than all vanilla plantation types. However, we observed a greater number of species and a higher inverse Simpson index in minimally managed vanilla plantations located within or near natural forest compared to intensively managed vanilla plantations. These findings are important and encouraging for animal conservation and sustainable crop cultivation in Madagascar, and suggest that newly created vanilla plantations, and already existing plantations, should endeavour to follow the more traditional, minimalistic management approach to improve sustainability and promote higher faunal diversity.
Humans are responsible for biodiversity loss in many related and sometimes conflicting ways. Human-wildlife conflict, commonly defined as any negative interaction between people and wildlife, is a primary contributor to wildlife extinction and a manifestation of the destructive relationship that people have with wildlife. The author presents this 'wicked' problem in a social and legal context and demonstrates that legal institutions structurally deny human-wildlife conflict, while exacerbating conflict, promoting values consistent with individual autonomy, and ignoring the interconnected vulnerabilities shared by human and non-human species alike. It is the use of international and state law that sheds light on existing conflicts, including dingo conflict on K'Gari-Fraser Island in Australia, elephant conflict in Northern Botswana, and the global wildlife trade contributing to COVID-19. This book presents a critical analysis of human-wildlife conflict and its governance, to guide lawyers, scientists and conservations alike in the transformation of the management of human-wildlife conflict.
The macroalgae of the Balleny Islands (66°15′S–67°35′S and 162°30′E–165°00′E) have been infrequently collected and the flora remains poorly known. This chain of islands is located on the edge of the Antarctic Circle in the northern Ross Sea, ~250 km north of the coast of northern Victoria Land, and it represents the most northerly land in the Ross Sea region. As well as being very remote, access to these islands is difficult given the highly variable prevailing ice conditions. We summarize the macroalgal floras of the Balleny Islands and the Ross Sea, including reporting new records, extending the known distribution of other taxa and highlighting the need for further taxonomic research on some of the most common and widespread species. Many of the taxa reported have been collected on few occasions and, as a consequence, there is insufficient material available, including reproductively mature samples, for some species to be fully documented. While these collections are providing intriguing insights into the relationships between the macroalgae found around the Antarctic continent, the full biodiversity of the Balleny Islands remains to be investigated, and further collections are required to enable detailed comparisons with other parts of the Antarctic region.
The conclusion summarizes and discusses the principal findings of the book, highlighting the role of temporal coordination dilemmas and Temporal Focal Points in patterns of continuity and change in international institutions. After relating these findings to other theoretical approaches, the chapter discusses the theoretical implications of the analysis contained in this book for the study of change in international institutions. The chapter provides an extended discussion of policy implications, including how international actors can employ the logic of temporal coordination in modernizing global institutions in the current international setting. It concludes with an analysis of the current context in global environmental and sustainable development politics, analyzing progress in combatting global challenges, such as climate change and the loss of biodiversity, and implementing the Sustainable Development Goals (SDGs). It argues that the international community has incentives to realize institutional change and that a Temporal Focal Point could soon emerge.
This chapter focuses on the 1992 United Nations Conference on Environment and Development (UNCED), the Rio “Earth Summit.” It shows how, despite incentives to address institutional dysfunction and mounting global environmental problems by institutionalizing sustainable development within the United Nations system, divergent expectations persisted until momentum built toward UNCED. The Rio conference, which marked the twentieth anniversary of the 1972 Stockholm conference, emerged as a Temporal Focal Point in United Nations environmental politics. Convergent expectations triggered a significant increase in political and analytical investments in change processes from state and non-state actors, leading to a transformation of the informational and political context. These investments produced significant institutional change, including the creation of the Commission on Sustainable Development (CSD) and the institutionalization of the World Bank-operated Global Environment Facility. States also launched the United Nations Framework Convention on Climate Change, the Convention on Biological Diversity, a set of Forest Principles, and the United Nations Convention to Combat Desertification.
This chapter analyzes United Nations environmental politics from 1993 to 2021, focusing heavily on the 2002 World Summit on Sustainable Development (WSSD), or the “Johannesburg summit,” and the 2012 “Rio+20” United Nations Conference on Sustainable Development (UNCSD). The chapter examines the institutional ambiguities created by the 1992 Rio “Earth Summit” and international efforts to address them. It analyzes in detail failed institutional bargaining surrounding WSSD and carries the empirical investigation forward to the Rio+20 summit. The second Rio Earth Summit constituted a Temporal Focal Point in the history of United Nations environment governance and precipitated large-scale institutional change. Among the significant institutional changes emerging from the conference were the transformation of the United Nations Environment Programme (UNEP), the creation of a High-Level Political Forum on Sustainable Development (HLPF), and the approval of a process for articulating the UN’s Sustainable Development Goals (SDGs) and the 2030 Agenda. The chapter also provides a brief discussion of more recent UN environmental cooperation, focusing on UNEP, the HLPF, and the SDGs, including progress in combatting climate change and the loss of biodiversity.
Land use change has transformed ecosystem pattern and process across most of the terrestrial biosphere, a global change that could be potentially catastrophic for both humankind and the environment. Chapter 5 explores how this threat is related to the underpricing of natural landscape in all economies, and how addressing this critical problem is essential to creating the incentives, institutions and innovations needed to change humankind’s relationship with nature. The underpricing of natural landscape also perpetuates rural poverty, and the impacts of land use change are borne increasingly by the poor. Decoupling development from excessive land use change leading to ecosystem decline is necessary to make our economies both more sustainable and inclusive. Global biodiversity conservation is also plagued by underfunding, as the international community struggles to compensate developing countries for protecting valuable terrestrial habitats. Collective action will require commitments not only by rich countries to assist poorer ones in protection and restoration efforts but also by the private sector to invest in nature to reduce the risks from biodiversity and ecosystem loss.
This dark parable of the Anthropocene describes the terrible assault of the Anthropoi on the sacred Living Mountain and on those who once flourished in its shadow. The Anthropoi with their armies and their savants who justify their actions enter the Valley, and desecration follows. They force the Valley-dwellers to aid their assault on their revered Living Mountain. Worse, the Anthropoi's insatiable desire eventually infects the Valley-dwellers themselves until they too willingly join the assault, climbing, digging, and exploiting the heights, even as its snows melt, crevasses widen, and avalanches destroy the Valley floor. The lone exception is one old woman who can still feel the Mountain's heartbeat with the soles of her feet and knows no one can master it. "The Ascent of the Anthropoi" lays bare modernity's consoling lie that growth is the key to justice and that instrumental knowledge trumps the sensuous acceptance of life within the constraints of Earth's bounty.
Life relies on mutualistic relationships among species, and on the constant rejuvenation of Earth’s materials. Mutualistic cities would do the same thing, enhancing biodiversity, clean air, better soils, fresh water, and stronger communities. Today, however, cities are far from mutualistic. Currently, more than 4 billion people live in cities, and that number is rising quickly. These conglomerations of humanity consume vast Earth resources, and, worst yet, disgorge astonishing amounts of waste into the atmosphere, water, land and sea around them. Unlike "smart cities" that rely on sophisticated technology to monitor and respond to environmental conditions, and unlike "sustainable cities" that stress reduction and reuse, the concept of a "mutualistic city" emphasizes regenerative cycles and virtuous feedback loops. These cities are the key to our future.
WTO rules must extend beyond the links between trade and climate change to strengthen the links between trade and other economic, environmental, and social dimensions of sustainable development., including the global crisis in biodiversity. New rules are needed to free trade in environmental goods and services and to discipline fisheries subsidies and fossil fuel subsidies while promoting sustainable energy.
Earth is rapidly losing free-living species. Is the same true for parasitic species? To reveal temporal trends in biodiversity, historical data are needed, but often such data do not exist for parasites. Here, parasite communities of the past were reconstructed by identifying parasites in fluid-preserved specimens held in natural history collections. Approximately 2500 macroparasites were counted from 109 English Sole (Parophrys vetulus) collected between 1930 and 2019 in the Salish Sea, Washington, USA. Alpha and beta diversity were measured to determine if and how diversity changed over time. Species richness of parasite infracommunities and community dispersion did not vary over time, but community composition of decadal component communities varied significantly over the study period. Community dissimilarity also varied: prior to the mid-20th century, parasites shifted in abundance in a seemingly stochastic manner and, after this time period, a canalization of community change was observed, where species' abundances began to shift in consistent directions. Further work is needed to elucidate potential drivers of these changes and to determine if these patterns are present in the parasite communities of other fishes of the Salish Sea.
From the Andes to the Himalayas, mountains have an extraordinary power to evoke a sense of the sacred. In the overwhelming wonder and awe that these dramatic features of the landscape awaken, people experience something of deeper significance that imbues their lives with meaning and vitality. Drawing on his extensive research and personal experience as a scholar and climber, Edwin Bernbaum's Sacred Mountains of the World takes the reader on a fascinating journey exploring the role of mountains in the mythologies, religions, history, literature, and art of cultures around the world. Bernbaum delves into the spiritual dimensions of mountaineering and the implications of sacred mountains for environmental and cultural preservation. This beautifully written, evocative book shows how the contemplation of sacred mountains can transform everyday life, even in cities far from the peaks themselves. Thoroughly revised and updated, this new edition considers additional sacred mountains, as well as the impacts of climate change on the sacredness of mountains.
As natural and anthropogenic forcings impel anticipated climate change, their effects on biodiversity and environmental sustainability are evident. A fundamental question that is often overlooked is: which changes in climate will cause the redistribution or extinction of threatened species? Here, we mapped and modelled the current and future geographical distributions of the four threatened medicinal plants – Aconitum heterophyllum Wall. ex Royle, Fritillaria cirrhosa D.Don, Meconopsis aculeata Royle and Rheum webbianum Royle – in Kashmir Himalaya using maximum entropy (MaxEnt) modelling. Species occurrence records were collated from detailed field studies carried out between the years 2010 and 2020. Four general circulation models for Representative Concentration Pathway (RCP) 4.5 and RCP8.5 climate change scenarios were chosen for future range changes over periods around 2050 (average for 2041–2060) and 2070 (average of 2061–2080). Notable differences existed between species in their responses to predictive environmental variables of temperature and precipitation. Increase in the most suitable habitat, except for A. heterophyllum and R. webbianum, were evident across Himalayan Mountain regions, while the Pir Panjal mountain region exhibited a decrease for all four species under future climate change scenarios. This study exemplifies the idiosyncratic response of narrow-range plants to expected future climate change and highlights conservation implications.
For many, declining biodiversity represents an emotionally and psychologically distant ‘cost’ – similar to how a number of people perceive climate change. Using an expectancy-value theory framework, we showed participants photographs that visibly illustrated the threat of biodiversity loss. Specifically, we tested a combination of preregistered and exploratory hypotheses through an online experiment (n = 843) to understand whether viewing photographs of plants and animals (with and without captions) bolstered people’s valuing of biodiversity and willingness to donate to a nature-focused charity relative to a control group. Participants who viewed photographs (without captions) valued biodiversity more and donated more to the nature-focused charity; those who viewed photographs with captions showed similar though more muted (non-statistically significant) effects. Follow-up mediation analyses on the photographs-only participants suggested that the photographs may have catalysed negative emotions that increased valuing of biodiversity and, in turn, increased donations. This study provides preregistered evidence that thoughtfully selected photographs boost people’s valuing of biodiversity and exploratory evidence that the pathway through which that might occur is more likely via negative emotions than through reduced psychological distance. Educators, conservationists, journalists and others may find these results informative as they develop strategies for addressing the acute problem of biodiversity loss.
