High‐Resolution Satellite Imagery Reveals Landscape‐Scale Benthic Habitat Changes in a Turbid Coral Reef

Remote Sensing in Ecology and Conservation, EarlyView.
High‐resolution satellite imagery and landscape metrics revealed a 77% decline in coral‐dominated habitats at Abrolhos Bank between 2010 and 2024, accompanied by macroalgal and zoanthid expansion. Spatial reorganisation indicates increasing fragmentation, homogenisation and loss of reef structural complexity.

When Norms Meet Markets: Environmental Governance and Digital Fast‐Fashion Platforms in Brazil

Sustainable Development, EarlyView.
ABSTRACT Environmental governance increasingly relies on consumer‐based mechanisms that assume that sustainability awareness translates into purchasing behaviour. This article investigates whether such mechanisms remain effective when consumption is organised through transnational digital platforms in contexts characterised by socioeconomic inequality.

A Social and Solidarity Economy Network's Evolution on Sustainability Discourses: Weak Versus Strong Sustainability

Sustainable Development, EarlyView.
ABSTRACT This study explores innovations concerning sustainability discourses in the case of a Social and Solidarity Economy (SSE) network. We analyse the incorporation of discursive elements characteristic of strong sustainability versus weak sustainability approaches in the different Solidarity Economy Principles Charters over time (2000, 2011, 2022),

Large parameter uncertainty persists in soil food web models integrating stoichiometry, respiration and assimilation

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil food web models are essential for linking animal diversity to carbon and nutrient cycling. However, it is unclear how soil animals regulate excess carbon when nutrient availability limits their growth and how to best represent animal respiration in these models. To

Elastase-induced pulmonary emphysema: insights from experimental models

Anais da Academia Brasileira de Ciências, 2011
Several distinct stimuli can be used to reproduce histological and functional features of human emphysema, a leading cause of disability and death. Since cigarette smoke is the main cause of emphysema in humans, experimental researches have attempted to ...

When is the bait worth the risk? A mechanistic model of a compensatory ecological trap in seabirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecological traps occur when organisms preferentially select habitats that reduce fitness. In seabird–fishery systems, fishery‐derived trophic subsidies can increase foraging success, reinforce habitat preference and indirectly enhance reproductive output or recruitment,

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.
