The ups and downs of space and time: topography in Yupno language, culture, and cognition

Much prior research has investigated how humans understand time using body-based contrasts like front/back and left/right. It has recently come to light, however, that some communities instead understand time using environment-based contrasts. Here, we present the richest portrait yet of one such case: the topographic system used by the Yupno of Papua New Guinea, in which the past is construed as downhill and the future as uphill. We first survey topographic concepts in Yupno language and culture, showing how they constitute a privileged resource for communicating about space. Next, we survey time concepts in Yupno, focusing on how topographic concepts are used to construe past, present, and future. We then illustrate how this topographic understanding of time comes to life in the words, hands, and minds of Yupno speakers. Drawing on informal interviews, we offer a view of the topographic system that goes beyond a community-level summary, and offers a glimpse of its individual-level and moment-to-moment texture. Finally, we step back to account for how this topographic understanding of time is embedded within a rich cognitive ecology of linguistic, cultural, gestural, and architectural practices. We close by discussing an elusive question: Why is the future uphill?

The Sensory and Cognitive Ecology of Nectar Robbing

Animals foraging from flowers must assess their environment and make critical decisions about which patches, plants, and flowers to exploit to obtain limiting resources. The cognitive ecology of plant-pollinator interactions explores not only the complex nature of pollinator foraging behavior and decision making, but also how cognition shapes pollination and plant fitness. Floral visitors sometimes depart from what we think of as typical pollinator behavior and instead exploit floral resources by robbing nectar (bypassing the floral opening and instead consuming nectar through holes or perforations made in floral tissue). The impacts of nectar robbing on plant fitness are well-studied; however, there is considerably less understanding, from the animal’s perspective, about the cognitive processes underlying nectar robbing. Examining nectar robbing from the standpoint of animal cognition is important for understanding the evolution of this behavior and its ecological and evolutionary consequences. In this review, we draw on central concepts of foraging ecology and animal cognition to consider nectar robbing behavior either when individuals use robbing as their only foraging strategy or when they switch between robbing and legitimate foraging. We discuss sensory and cognitive biases, learning, and the role of a variable environment in making decisions about robbing vs. foraging legitimately. We also discuss ways in which an understanding of the cognitive processes involved in nectar robbing can address questions about how plant-robber interactions affect patterns of natural selection and floral evolution. We conclude by highlighting future research directions on the sensory and cognitive ecology of nectar robbing.

Sensory and Cognitive Ecology of Bats

We see stunning morphological diversity across the animal world. Less conspicuous but equally fascinating are the sensory and cognitive adaptations that determine animals’ interactions with their environments and each other. We discuss the development of the fields of sensory and cognitive ecology and the importance of integrating these fields to understand the evolution of adaptive behaviors. Bats, with their extraordinarily high ecological diversity, are ideal animals for this purpose. An explosion in recent research allows for better understanding of the molecular, genetic, neural, and behavioral bases for sensory ecology and cognition in bats. We give examples of studies that illuminate connections between sensory and cognitive features of information filtering, evolutionary trade-offs in sensory and cognitive processing, and multimodal sensing and integration. By investigating the selective pressures underlying information acquisition, processing, and use in bats, we aim to illuminate patterns and processes driving sensory and cognitive evolution. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 52 is November 2021.

Ecologizing Knowledge: Considerations to Rethink Life in the Ever-Changing World Triggered by the Pandemic

We present a theoretical essay approaching the question: according to which paradigm will we reorganize ourselves as a human society facing the experience of the Pandemic? To ecologize knowledges by articulating and establishing relations among different theories and forms of knowledge, we offer clues and possibilities to create forms of acting in life, especially in education practices, taking this moment we are living in as a trigger for transformations. In this way, we suggest the method of complexity as a strategy to redimension our way of understanding what we are living and transforming our way of acting. We emphasize the need of overcoming the current objectivism and rationalism, and proposing the systemic vision that includes the reflective, active, strategist subject as co-creator of the reality in which he lives. In this way, we suggest that educational practices need to be configured as a cognitive ecology, the result of the articulation of various contexts, coexistence scenarios, where teachers and students act together, taking care of each other and co-creating learning contexts in the experience. This approach can give rise to a form of education founded on a dynamic based on cooperating and sharing in circularity, surpassing control and judgment and enhancing the empowerment of being.

Evidence of anticipatory immune and hormonal responses to predation risk in an echinoderm

Recent efforts have been devoted to the link between responses to non-physical stressors and immune states in animals, mostly using human and other vertebrate models. Despite evolutionary relevance, comparatively limited work on the appraisal of predation risk and aspects of cognitive ecology and ecoimmunology has been carried out in non-chordate animals. The present study explored the capacity of holothuroid echinoderms to display an immune response to both reactive and anticipatory predatory stressors. Experimental trials and a mix of behavioural, cellular and hormonal markers were used, with a focus on coelomocytes (analogues of mammalian leukocytes), which are the main components of the echinoderm innate immunity. Findings suggest that holothuroids can not only appraise threatening cues (i.e. scent of a predator or alarm signals from injured conspecifics) but prepare themselves immunologically, presumably to cope more efficiently with potential future injuries. The responses share features with recently defined central emotional states and wane after prolonged stress in a manner akin to habituation, which are traits that have rarely been shown in non-vertebrates, and never in echinoderms. Because echinoderms sit alongside chordates in the deuterostome clade, such findings offer unique insights into the adaptive value and evolution of stress responses in animals.

Cognitive Ecology in the Age of the Internet

The article deals with the problem of intellectual behavior in the era of development of the Internet and social networks. Just as geo-ecology has put the values of nature conservation at the forefront over those of economic gain, so cognitive ecology puts intellectual values at the forefront of the cognitive process. The author substantiates the idea that the Internet has its own cognitive ecology. An overabundance of information requires more complex skills in evaluating and analyzing information, as well as changing value-based intellectual attitudes. It is argued that the theoretical basis for the analysis of cognitive ecology in the Internet age can be the epistemology of virtues, in which various intellectual virtues and vices are studied. The article lists some intellectual virtues and vices that can be demanded when working on the Internet. These intellectual virtues include: open-mindedness, intellectual caution, intellectual courage, intellectual thoroughness, etc. It is shown that manifestation of intellectual virtues is necessary to navigate in epistemologically “unfriendly” environment of the Internet.

Pleistocene Water Crossings and Adaptive Flexibility Within the Homo Genus

Pleistocene water crossings, long thought to be an innovation of Homo sapiens, may extend beyond our species to encompass Middle and Early Pleistocene Homo. However, it remains unclear how water crossings differed among hominin populations, the extent to which Homo sapiens are uniquely flexible in these adaptive behaviors, and how the tempo and scale of water crossings played out in different regions. I apply the adaptive flexibility hypothesis, derived from cognitive ecology, to model the global data and address these questions. Water-crossing behaviors appear to have emerged among different regional hominin populations in similar ecologies, initially representing nonstrategic range expansion. However, an increasing readiness to form connections with novel environments allowed some H. sapiens populations to eventually push water crossings to new extremes, moving out of sight of land, making return crossings to maintain social ties and build viable founder populations, and dramatically shifting subsistence and lithic provisioning strategies to meet the challenges of variable ecological settings.
