Abstract For decades, people have reduced the transmission of pathogens by adding low‐quality hosts to managed environments like agricultural fields. More recently, there has been interest in whether similar ‘dilution effects’ occur in natural disease systems, and whether these effects are eroded as diversity declines. For some pathogens of plants, humans and other animals, the highest‐quality hosts persist when diversity is lost, so that high‐quality hosts dominate low‐diversity communities, resulting in greater pathogen transmission. Meta‐analyses reveal that these natural dilution effects are common. However, studying them remains challenging due to limitations on the ability of researchers to manipulate many disease systems experimentally, difficulties of acquiring data on host quality and confusion about what should and should not be considered a dilution effect. Because dilution effects are widely used in managed disease systems and have been documented in a variety of natural disease systems, their existence should not be considered controversial. Important questions remain about how frequently they occur and under what conditions to expect them. There is also ongoing confusion about their relationships to both pathogen spillover and general biogeographical correlations between diversity and disease, which has resulted in an inconsistent and confusing literature. Progress will require rigorous and creative research.

Abstract In ecologically pristine ecosystems, top-down effects of apex predators play a fundamental role in shaping trophic cascades and structuring ecosystems, but in human-modified landscapes anthropogenic effects may markedly alter the ecological role of predators. In particular, human-provisioned food subsidies represent a serious concern for the conservation of apex predators, even though little empirical attention has been given to this aspect in assessing conservation outcomes. To assess the extent to which anthropogenic food subsidies affected feeding ecology of a protected wolf (Canis lupus) population in a human-modified landscape, we integrated scat-analysis (n = 1141 from 4 packs; Jan 2005–Mar 2009) and winter field inspections of Global Positioning System telemetry re-locations (n = 595 clusters and 96 single locations from 5 wolves in 5 packs and 3 floaters; 2008–2011) of wolves living in a historical national park of central Italy hosting both wild prey and livestock at high densities. We revealed that livestock dominated the wolf diet (mean biomass = 63.3 ± 14.2% SD), secondarily supplemented by wild prey (36.7 ± 5.3%, mostly wild boar [Sus scrofa], roe deer [Capreolus capreolus], and red deer [Cervus elaphus]). During winter, we revealed a higher propensity of wolves to scavenge (72.5%; n = 91 feeding events) rather than killing prey, and feeding behavior was affected by prey type (i.e., domestic vs wild ungulates) as the large majority of scavenged carrions (75.8%) were livestock carcasses abandoned on the ground that died for causes different from predation. Feeding behavior of wolves was not affected by social affiliation (i.e., pack members vs solitary wolves), indicating that pack members, even if aided by cooperative hunting, were equally likely than solitary wolves to scavenge rather than killing prey; yet, 27.5% of winter feeding events involved predation, exclusively targeted to wild prey. Our findings indicate that large livestock carrion subsidies may strongly depress predatory behavior in wolves, despite the occurrence of an abundant wild prey community, and have relevant ecological, evolutionary and management implications. Reliance on human-provided livestock carrion subsidies likely alters the ecological role of wolves by reducing their top-down cascading effects on the ecosystem, and this has relevant implications for the conservation of wolves and other apex predators in national parks. Accordingly, we call for more strict regulations to govern livestock management and practices and argue that, at least in national parks, conservation goals of apex predators need to explicitly consider their ecological role.

This article applies a feminist political ecology framework to analyze a particular case of human-wildlife interaction from northeastern India, linking it to the emerging paradigm of 'decolonized conservation.' Through the oral testimonies of local community members with regard to living close to wild Asian elephants in a forest-agriculture landscape matrix of rural Assam, this article argues that place-based conceptualizations of 'wildlife', 'forest dependency' and 'living with wildlife' are affected by gendered roles and responsibilities, gendered access to spaces and gendered interaction with wildlife. By doing so, this article argues for (i) extending the discourse on 'decolonized conservation' towards the role of gender in rethinking these place-based conceptualizations and (ii) bringing forward such 'en-gendering' into redesigning wildlife policies, as that will have the potential of ensuring feminist environmental justice as well as positive conservation outcomes.

Abstract Socioeconomic demand for natural capital is causing catastrophic losses of biodiversity and ecosystem functionality, most notably in regions where socioeconomic‐and eco‐systems compete for natural capital, e.g., energy (animal or plant matter). However, a poor quantitative understanding of what natural capital is needed to support biodiversity in ecosystems, while at the same time satisfy human development needs—those associated with human development within socioeconomic systems—undermines our ability to sustainably manage global stocks of natural capital. Here we describe a novel concept and accompanying methodology (relating the adult body mass of terrestrial species to their requirements for land area, water, and energy) to quantify the natural capital needed to support terrestrial species within ecosystems, analogous to how natural capital use by humans is quantified in a socioeconomic context. We apply this methodology to quantify the amount of natural capital needed to support species observed using a specific surveyed site in Scotland. We find that the site can support a larger assemblage of species than those observed using the site; a primary aim of the rewilding project taking place there. This method conceptualises, for the first time, a comprehensive “dual‐system” approach: modelling natural capital use in socioeconomic‐and eco‐systems simultaneously. It can facilitate the management of natural capital at the global scale, and in both the conservation and creation (e.g., rewilding) of biodiversity within managed ecosystems, representing an advancement in determining what socioeconomic trade‐offs are needed to achieve contemporary conservation targets alongside ongoing human development.

Currently, a sufficient amount of data has been accumulated on the negative COVID-19 pandemic impact and its socio-economic consequences on human mental health and mental ecology in general. The public health strategies success used to cope with pandemics is largely determined by psychological factors and mental values prevailing in the community. The aim was to systematize the psychological response features of various social, professional and national groups representatives during the COVID-19 period within the framework of the main mental ecology provisions. The review methodological basis was the use of the World Health Organization (WHO) documents and open sources of the Scopus and Web of Science databases on the population mental health in the COVID-19 pandemic conditions. A significant increase in adaptive and anxiety-depressive disorders during the COVID-19 pandemic is shown. Among the specific mental phenomena associated with the pandemic, coronaphobia, COVID-19-stress syndrome, covid-dissidence manifestations with involvement in conspiracy theories and mythological thinking were identified. The negative infodemia impact on the mental ecology, as well as adherence to anti-epidemic measures and readiness for vaccination, has been established. Negative trends have been demonstrated in communities where the maximum infection and death risk is associated with low adherence to epidemiological measures and vaccination refusal. Belonging to certain social or professional groups largely determines a person's behavior in relation to a new coronavirus infection within the framework of accepted social norms. Based on the analysis of a large domestic and international data number on the impact of the COVID-19 pandemic emergency situation on the human psyche, its significant adverse contribution to the overall mental ecology was noted. The necessity of developing special therapeutic and psycho-prophylactic programs aimed at coping with the stress pandemic impact and treating affective disorders, countering infodemia and strengthening behavioral patterns to maintain mental health and person well-being is substantiated.

The paper analyses the articles of the famous Tatar historian G. Gubaydullin published in his student years in the magazine “Maktap” (1913). The articles are devoted to the problems of teaching logic and history in Tatar madrasas at the beginning of the twentieth century. The introduction of new secular subjects into the learning process was especially relevant for the national school. Moreover, new teaching methods were developed in the absence of school textbooks in the Tatar language. Gubaydullin, as a future professional historian, understood full well the importance of humanitarian subjects, especially history and logic, in the formation of national identity of young people. In the article “Din madrasalarenda tarikh ukytu” (“Teaching history in religious madrassas”) he discusses the methodological recommendations for teachers and shakirds. The recommendations were important because Tatar educators had no experience in teaching history. Logic was studied in old-fashioned madrasas, but after the 1905 revolution the training programs were changed and there was a demand for a new textbook which would meet the requirements of the era. The historian writes about this issue in the article “Din madrasalarenda mantyk” (“Logic in religious madrassas”). At the beginning of the new century, the Tatar public had heated discussions about the concept of “nation”. G. Gubaydullin expressed his opinion about the preservation of the unity of the Turkic peoples in the article “Iske tel ham millat” (“Old language and nation”). He considered it necessary to introduce a new school subject – the Chagatay language for a better understanding of the ancient Turkic literature. The analysis of these articles gives an idea of the scholar’s views on national pedagogy.

Vector-borne diseases (VBDs) are embedded within complex socio-ecological systems. While research has traditionally focused on the direct effects of VBDs on human morbidity and mortality, it is increasingly clear that their impacts are much more pervasive. VBDs are dynamically linked to feedbacks between environmental conditions, vector ecology, disease burden, and societal responses that drive transmission. As a result, VBDs have had profound influence on human history. Mechanisms include: (1) killing or debilitating large numbers of people, with demographic and population-level impacts; (2) differentially affecting populations based on prior history of disease exposure, immunity, and resistance; (3) being weaponised to promote or justify hierarchies of power, colonialism, racism, classism and sexism; (4) catalysing changes in ideas, institutions, infrastructure, technologies and social practices in efforts to control disease outbreaks; and (5) changing human relationships with the land and environment. We use historical and archaeological evidence interpreted through an ecological lens to illustrate how VBDs have shaped society and culture, focusing on case studies from four pertinent VBDs: plague, malaria, yellow fever and trypanosomiasis. By comparing across diseases, time periods and geographies, we highlight the enormous scope and variety of mechanisms by which VBDs have influenced human history.

Human population expansion into wildlife habitats has increased interest in the behavioural ecology of human-wildlife interactions. To date, however, the socio-ecological factors that determine whether, when or where wild animals take risks by interacting with humans and anthropogenic factors still remains unclear. We adopt a comparative approach to address this gap, using social network analysis (SNA). SNA, increasingly implemented to determine human impact on wildlife ecology, can be a powerful tool to understand how animal socioecology influences the spatiotemporal distribution of human-wildlife interactions. For 10 groups of rhesus, long-tailed, and bonnet macaques (Macaca spp.) living in anthropogenically-impacted environments in Asia, we collected data on human-macaque interactions, animal demographics, and macaque-macaque agonistic and affiliative social interactions. We constructed 'human co-interaction networks' based on associations between macaques that interacted with humans within the same time and spatial locations, and social networks based on macaque-macaque allogrooming behaviour, affiliative behaviours of short duration (agonistic support, lip-smacking, silent bare-teeth displays, and non-sexual mounting), and proximity. Pre-network permutation tests revealed that, within all macaque groups, specific individuals jointly took risks by repeatedly, consistently co-interacting with humans within and across time and space. GLMMs revealed that macaques' tendencies to co-interact with humans was positively predicted by their tendencies to engage in short-duration affiliative interactions and tolerance of conspecifics, although the latter varied across species (bonnets>rhesus>long-tailed). Male macaques were more likely to co-interact with humans than females. Neither macaques' grooming relationships nor their dominance ranks predicted their tendencies to co-interact with humans. Our findings suggest that, in challenging anthropogenic environments, less (compared to more) time-consuming forms of affiliation, and additionally greater social tolerance in less ecologically flexible species with a shorter history of exposure to humans, may be key to animals' joint propensities to take risks to gain access to resources. For males, greater exploratory tendencies and less energetically demanding long-term life-history strategies (compared to females), may also influence such joint risk-taking. From conservation and public health perspectives, wildlife connectedness within such co-interaction networks may inform interventions to mitigate zoonosis, and move human-wildlife interactions from conflict towards co-existence.

Because of human domination, the world faces two major environmental problems—species extinctions and climate change. The still‐elusive solutions to these global problems must address interlinked ecological, economic, political, ethical and cultural constraints and trade‐offs, and will require unprecedented international cooperation. Major advances in ecological research will be essential and will require that ecology become a more mechanistic and predictive science. Research advances in disciplines ranging from evolution and population ecology to community and ecosystem ecology could greatly contribute to the formulation of viable, sustainable solutions. Synthesis. Because solutions must also be equitable, ethical, economically viable and societally sustainable, it will be increasingly important for ecologists to be part of multidisciplinary teams that evaluate the full range of interlinked environmental and societal impacts of alternative potential policies.

ABSTRACT In recent years, the study of ecolinguistics has made great progress in the integration of other disciplines and in discourse analysis. Ecological discourse analysis effectively illustrates the ecological potentials in discourse from a micro-level perspective, but the macro process of these ecological potentials is not clear. In this paper, the macro process of language intervening society is presented by illustrating the landsense cr eation of language, based on landsenses ecology and taking harmonious discourse as an example. And McNemar test is used to demonstrate the interventional function of anti-fur language in subjects’ psychology and behavior, following the discussion of the hierarchical relationship among fur advertisements, Maslow’s hierarchy of needs and ecosystem services. Landsenses ecology and ecolinguistics are disciplines with the vision of realizing the sustainable development of ecosystem and human society, and the macro-intervention process of language can be effectively clarified by the concept of landsense creation in landsenses ecology, which can fully demonstrate the role of language in the sustainable relationship between human beings and other living beings.

A major starting point in industrial ecology (IE) is that reaching ecological sustainability requires understanding relations between human actions and material (tangible) flows. IE studies have enabled assessments of different technical and sociotechnical configurations but only to a limited degree provided concepts that support the design of interventions for industrial ecologies. We contribute by proposing a sociomaterial flow approach, here applied to life cycle thinking. After problematizing some common concepts in IE, the key concepts, a procedure, and some applied variants of the proposed sociomaterial approach are presented. The approach is theoretically grounded in related sociomaterial research. This body of theories underpins our conceptualization of how flows in, for example, a product life cycle can be related to nets of human actions within one rather than several analytical frames. The sociomaterial interaction point (SMIP) is a key concept in our approach for the sociomaterial connection between material flows and actor networks. A SMIP can be described as the interactions where humans come closest to the flows. The conceptualization of the methodology provides a framework for exploring actor and action networks shaping material flows and a basis for a relational analysis of governance, organization, and management of the flows in industrial ecologies. A sociomaterial approach to flow studies can therefore help in designing more concrete sustainability interventions in industrial ecologies.

Decades of research have examined human-computer interaction with or across multiple (computational) artifacts as artifact ecologies, communicative ecologies, device ecologies, information ecologies, and other related conceptualisations. Although rich on observations and concepts, the works are largely self-contained and focused on using and developing concepts internally, with little ambitions toward synthesizing and strengthening what we know about these different theoretical concepts. In this paper we take stock of the literature on ecologies et al. in HCI and CSCW with the aim of identifying key positions, differences, similarities, and sub-concepts, as well as opportunities moving forward. From a reviewed corpus of 129 publications we consolidate 54 concepts into four influential positions and identify cross-cutting themes, conceptual gaps and challenges moving forward. In addition, we discuss issues related to the disconnected nature and theoretical quality of the concepts and how that impacts implicit theorising within our research community.

Abstract Our understanding of ecological processes is built on patterns inferred from data. Applying modern analytical tools such as machine learning to increasingly high dimensional data offers the potential to expand our perspectives on these processes, shedding new light on complex ecological phenomena such as pathogen transmission in wild populations. Here, we propose a novel approach that combines data mining with theoretical models of disease dynamics. Using rodents as an example, we incorporate statistical differences in the life history features of zoonotic reservoir hosts into pathogen transmission models, enabling us to bound the range of dynamical phenomena associated with hosts, based on their traits. We then test for associations between equilibrium prevalence, a key epidemiological metric and data on human outbreaks of rodent‐borne zoonoses, identifying matches between empirical evidence and theoretical predictions of transmission dynamics. We show how this framework can be generalized to other systems through a rubric of disease models and parameters that can be derived from empirical data. By linking life history components directly to their effects on disease dynamics, our mining‐modelling approach integrates machine learning and theoretical models to explore mechanisms in the macroecology of pathogen transmission and their consequences for spillover infection to humans.

Suffering has been a topic of considerable discussion in the fields of medicine and palliative care, yet few studies have reported causal evidence linking the experience of suffering to health and well-being. In this three-wave prospective cohort study, we explore the potential psychological implications of suffering during the COVID-19 pandemic by examining relations among suffering, mental health, and psychological well-being in a sample of U.S. adults living with chronic health conditions. We analyzed data from n = 184 participants who completed assessments one month before the SARS-CoV-2 outbreak was declared a pandemic by the World Health Organization (February 2020) and then two months (April 2020) and four months later (May/June 2020). Analyses controlled for a range of factors, including sociodemographic characteristics, physical health, religious/spiritual factors, psychological characteristics, and prior values of the predictor and each of the outcomes assessed one month before the COVID-19 pandemic. Results of the primary analysis indicated that greater overall suffering assessed one month into the COVID-19 pandemic was associated with lower psychological well-being (β = -.17, 95% CI: -.29, -.05) and higher levels of anxiety (β = .27, 95% CI: .13, .41) and depression (β = .16, 95% CI: .03, .29) two months later. In a secondary analysis that explored anxiety, depression, and psychological well-being as candidate antecedents of suffering, depression assessed one month into the COVID-19 pandemic was most strongly associated with worse overall suffering two months later. We highlight the implications of the findings for high-risk populations who are suffering amidst the challenges of the COVID-19 pandemic. Potential benefits of both integrating assessments of suffering into screening procedures and addressing experiences of suffering in mental health service settings are discussed.

Abstract The coronavirus disease 2019 (COVID‐19) pandemic introduced an abrupt change in human behavior globally. Here, we discuss unique insights the pandemic has provided into the eco‐evolutionary role of pathogens in ecosystems and present data that indicates the pandemic may have fundamentally changed our learning choices. COVID‐19 has indirectly affected many organisms and processes by changing the behavior of humans to avoid being infected. The pandemic also changed our learning behavior by affecting the relative importance of information and forcing teaching and learning into a framework that accommodates human behavioral measures to avoid disease transmission. Not only are these indirect effects on the environment occurring through a unique mechanistic pathway in ecology, the pandemic along with its effects on us provides a profound example of the role risk can play in the transmission of information between the at risk. Ultimately, these changes in our learning behavior led to this special issue “Taking learning online in Ecology and Evolution.” The special issue was a call to the community to take learning in new directions, including online and distributed experiences. The topics examined include a significant component of DIY ecology and evolution that is experiential but done individually, opportunities to use online tools and apps to be more inclusive, student‐focused strategies for teaching online, how to reinvent conferences, strategies to retain experiential learning safely, emerging forms of teaching such as citizen science, apps and podcasting, and ideas on how to accommodate ever changing constraints in the college classroom, to name a few. The collective consensus in our fields is that these times are challenging but we can continue to improve and innovate on existing developments, and more broadly and importantly, this situation may provide an opportunity to reset some of the existing practices that fail to promote an effective and inclusive learning environment.

Australopithecus anamensis is a pivotal species in human evolution. It is likely to be the direct ancestor of Australopithecus afarensis and the species that may have given rise to the Homo and Paranthropus lineages. It had a suite of adaptations for habitual bipedalism and a diet that differed from that of earlier hominin species. Under what environmental and ecological conditions did this suite of adaptations arise? The early Pliocene site of Kanapoi in the Lake Turkana Basin of Kenya has the largest sample of A. anamensis in eastern Africa and a rich record of fossil vertebrates. Most Kanapoi fossils are chronologically well constrained by radiometrically dated tephras between the ages of 4.2 and 4.1 million years ago. Sedimentological, isotopic, and faunal data indicate that the environments of Kanapoi during the early Pliocene had a complex range of vegetation types that included closed woodlands, shrubs, and grasslands near a river (for most of the sequence) or lake. These were dynamic landscapes that could shift rapidly from fluvial to lacustrine conditions, and then back. Australopithecus anamensis shared its environments with at least 10 species of very large herbivores, which undoubtedly played a major role in modifying the landscape by opening wooded areas and providing pathways for bipedal hominins. Hominins may have competed for terrestrial resources with abundant suids (Nyanzachoerus and Notochoerus) and for arboreal resources with monkeys (Parapapio being the most common cercopithecid). Kanapoi had a formidable group of predators that included a very abundant species of hyena (Parahyaena howelli), two sabre-tooth felids (Dinofelis and Homotherium), a giant otter (Enhydriodon cf. dikikae), and three species of crocodiles. Various measures of abundance indicate that A. anamensis was an important component of the Kanapoi early Pliocene ecosystems, and that its key adaptations allowed this species to thrive in complex and dynamic landscapes.

Abstract Media multitasking has become an inseparable part of the media routine for many Internet users as it is being retribalized, as a multisensory computer-mediated behavior, in the mobile media age. Guided by McLuhan's media ecology theory, this study examined the hierarchical relationships between media multitasking and media generations, mobile media use, and need for cognition among users in the United States and China (N = 1,340). After gender was controlled, media generations (defined as those growing up with or without the pervasive use of mobile media) was directly associated with media multitasking. Moreover, mobile media power use mediated the relationship between media generations and media multitasking. The personality construct of need for cognition was also found to play a critical role in performing multitasking. These findings indicate that mobile media technologies are reactivating multiple human senses in multitaskers, which might be a result of the evolutionary process spearheaded by the ubiquity of mobile media technologies. Thus, it is high time to revisit media multitasking as a new normal and access it as a multisensory behavior. McLuhan's media ecology theory helps understand the evolution of media multitasking, which may no longer be as simple as a technology distraction to users.

As a result of ecological and social drivers, the management of problems caused by wildlife is becoming more selective, often targeting specific animals. Narrowing the sights of management relies upon the ecology of certain 'problem individuals' and their disproportionate contribution to impacts upon human interests. We assess the ecological evidence for problem individuals and confirm that some individuals or classes can be both disproportionately responsible and more likely to reoffend. The benefits of management can sometimes be short-lived, and selective management can affect tolerance of wildlife for better or worse, but, when effectively targeted, selective management can bring benefits by mitigating impact and conflict, often in a more socially acceptable way.
