Three-dimensional digital mapping of ecosystems: a new era in spatial ecology
Ecological processes occur over multiple spatial, temporal and thematic scales in three-dimensional (3D) ecosystems. Characterizing and monitoring change in 3D structure at multiple scales is challenging within the practical constraints of conventional ecological tools. Remote sensing from satellites and crewed aircraft has revolutionized broad-scale spatial ecology, but fine-scale patterns and processes operating at sub-metre resolution have remained understudied over continuous extents. We introduce two high-resolution remote sensing tools for rapid and accurate 3D mapping in ecology—terrestrial laser scanning and structure-from-motion photogrammetry. These technologies are likely to become standard sampling tools for mapping and monitoring 3D ecosystem structure across currently under-sampled scales. We present practical guidance in the use of the tools and address barriers to widespread adoption, including testing the accuracy of structure-from-motion models for ecologists. We aim to highlight a new era in spatial ecology that uses high-resolution remote sensing to interrogate 3D digital ecosystems.

The care economy
Care is the foundation of organic life. But its fate in the economy is precarious and uncertain. The labour of care is arduous and underpaid. Yet without it health and vitality are impossible. Care itself ends up leading a curious dual life. In our hearts it's honoured as an irreducible good. But in the market it's treated as a second class citizen - barely recognised in the relentless rush for productivity and wealth. How did we arrive in this dysfunctional place? And what can we do to change things? What would it mean to take health seriously as a societal goal? What would it take to adopt care as an organising principle in the economy? Renowned ecological economist Tim Jackson sets out to tackle these questions in this timely and deeply personal book.

Thresher Sharks Use Tail-Slaps as a Hunting Strategy
The hunting strategies of pelagic thresher sharks (Alopias pelagicus) were investigated at Pescador Island in the Philippines. It has long been suspected that thresher sharks hunt with their scythe-like tails but the kinematics associated with the behaviour in the wild are poorly understood. From 61 observations recorded by handheld underwater video camera between June and October 2010, 25 thresher shark shunting events were analysed. Thresher sharks employed tail-slaps to debilitate sardines at all times of day. Hunting events comprised preparation, strike, wind-down recovery and prey item collection phases, which occurred sequentially. Preparation phases were significantly longer than the others, presumably to enable a shark to windup a tail-slap. Tail-slaps were initiated by an adduction of the pectoral fins, a manoeuvre that changed a thresher shark's pitch promoting its posterior region to lift rapidly, and stall its approach. Tail-slaps occurred with such force that they may have caused dissolved gas to diffuse out of the water column forming bubbles. Thresher sharks were able to consume more than one sardine at a time, suggesting that tail-slapping is an effective foraging strategy for hunting schooling prey. Pelagic thresher sharks appear to pursue sardines opportunistically by day and night, which may make them vulnerable to fisheries. Alopiids possess specialist pectoral and caudal fins that are likely to have evolved, at least in part, for tail-slapping. The evidence is now clear; thresher sharks really do hunt with their tails.

Where do people experience flow in the 21st century? Re-assessing activities and environments for flow
Flow supports psychological wellbeing. But where do optimal experiences of flow occur? Existing studies of flow activities are increasingly outdated and don’t account for changing patterns of time use. Further, the physical environments where flow experiences happen have not been empirically examined. This research explores flow activities and environments within a UK-based (Study 1, n = 4000) and international (Study 2, n = 839) sample. Commonly reported flow activities were largely consistent with existing research, with activities such as work, sport, reading, arts, and contemplative practices being frequently mentioned. Flow environments were varied, but the home and nature were prominent themes. Whilst certain flow activities tended to be reported alongside certain flow environments (e.g. sports outdoors and computer in residential spaces), others (e.g. art, music, reading) were not associated with specific locations. Together, findings consolidate understandings of the common sites of flow and provide preliminary insights into the role physical environments might play in supporting flow.

Three‐dimensional mapping reveals scale‐dependent dynamics in biogenic reef habitat structure
Habitat structure influences a broad range of ecological interactions and ecosystem functions across biomes. To understand and effectively manage dynamic ecosystems, we need detailed information about habitat properties and how they vary across spatial and temporal scales. Measuring and monitoring variation in three‐dimensional (3D) habitat structure has traditionally been challenging, despite recognition of its importance to ecological processes. Modern 3D mapping technologies present opportunities to characterize spatial and temporal variation in habitat structure at a range of ecologically relevant scales. Biogenic reefs are structurally complex and dynamic habitats, in which structure has a pivotal influence on ecosystem biodiversity, function and resilience. For the first time, we characterized spatial and temporal dynamics in the 3D structure of intertidal Sabellaria alveolata biogenic reef across scales. We used drone‐derived structure‐from‐motion photogrammetry and terrestrial laser scanning to characterize reef structural variation at mm‐to‐cm resolutions at a habitat scale (~35 000 m2) over 1 year, and at a plot scale (2500 m2) over 5 years (2014–2019, 6‐month intervals). We found that most of the variation in reef emergence above the substrate, accretion rate and erosion rate was explained by a combination of systematic trends with shore height and positive spatial autocorrelation up to the scale of colonies (1.5 m) or small patches (up to 4 m). We identified previously undocumented temporal patterns in intertidal S. alveolata reef accretion and erosion, specifically groups of rapidly accreting, short‐lived colonies and slow‐accreting, long‐lived colonies. We showed that these highly dynamic colony‐scale structural changes compensate for each other, resulting in seemingly stable reef habitat structure over larger spatial and temporal scales. These patterns could only be detected with the use of modern 3D mapping technologies, demonstrating their potential to enhance our understanding of ecosystem dynamics across scales.
Modern 3D mapping technologies present opportunities to investigate spatial and temporal variation in habitat structure across ecologically relevant scales. We used 3D mapping to characterize biogenic reef structural variation at mm‐to‐cm resolutions, at plot to habitat extents, over 1–5 years. We reveal previously undocumented spatial and temporal patterns in reef structure dynamics, providing insight into the ecology of these complex habitats.
