Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow
Remote Sensing in Ecology and Conservation, EarlyView.This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).

Remote Sensing in Ecology and Conservation, EarlyView.Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

Remote Sensing in Ecology and Conservation, EarlyView.Autonomous fixed‐wing drones operating beyond visual line of sight of the pilot were used to conduct the first aerial, multi‐species baseline reference survey at the sub‐Antarctic island of South Georgia. Long‐term population monitoring in this remote, challenging environment has historically proved difficult, with terrestrial monitoring generally ...

Remote Sensing in Ecology and Conservation, EarlyView.Adélie penguins gather in colonies as standing or prone adults, individual chicks, and chick crèches. From drone images, we distinguish adults and chicks by their plumage, identify adult postures by body shape, and estimate the size of chick groups from the area they occupy. We map these groups and measure how closely penguins live together.

Sustainable Development, EarlyView.ABSTRACT Sustainability represents a complex issue in which scientific knowledge inevitably coexists with the subjective perception of humans in its turn influenced by civilization, cultural but also unconscious aspects. These results emerge with evidence from a critical analysis of the main definitions of sustainability delivered by credited entities (

Right to Food in Sub‐Saharan Africa: Challenges, Policies, and Sustainable Strategies
Sustainable Development, EarlyView.ABSTRACT This article examines the multifaceted issue of food security in Sub‐Saharan Africa and the critical importance of upholding rights to food in the region. It explores the challenges posed by food insecurity, analyzes existing policies and interventions, and proposes sustainable strategies to enhance food security.

Sustainable Development, EarlyView.ABSTRACT This study introduces the ‘global forestation network’ (GFN)—an arrangement of actors that shape afforestation, reforestation, and forest restoration activities worldwide. These activities typically involve planting trees, and are motivated by supporting biodiversity, local communities, and climate change mitigation. At the GFN's core sit the ‘

Small Methods, EarlyView.Graphical Abstract. High‐speed atomic force microscopy enables real‐time, label‐free visualization of antibody interactions with individual extracellular vesicles. By quantifying binding frequency and dwell time, this approach reveals functional PD‐L1 accessibility that cannot be inferred from protein abundance alone, uncovering nanoscale heterogeneity
