Not just semantics: CO2 fertilization can be a disturbance leading to worldwide forest degradation
The physiological effects of increased atmospheric CO2 (CO2 fertilization) on intact forests are generally seen as a process that might buffer them against the impacts of climate change. However, CO2 fertilization can also cause adverse changes in forest conditions, such as alterations in species composition and reduced ecosystem moisture availability.

ABSTRACT Aim Fire significantly contributes to Amazonian degradation, with igapó forests (seasonally flooded by blackwater rivers) being especially vulnerable. Igapó forests support species adapted to seasonal flooding, making fire a critical threat to these specialised organisms.

“Captains of the Sands”: Urban Illicit Ecologies and Sandscapes in Rio de Janeiro
Abstract Urban Political Ecology (UPE) has explored human–soil relations, emphasising the political dimensions of environmental degradation in and through urbanisation. However, UPE lacks critical reflection on governance collusions with illicit actors.

Explore before you restore: Incorporating complex systems thinking in ecosystem restoration
By illustrating how key Complex Systems Science (CSS) concepts linked to non‐linear threshold behaviour can impact restoration outcomes through influencing recovery trajectories, our framework Explore Before You Restore demonstrates the need to incorporate Complex Systems thinking in ecosystem restoration. We argue that inclusion of CSS assessment into

Multiple stressors alter greenhouse gas concentrations in streams through local and distal processes
We found that the simultaneous occurrence of several human‐induced stressors in streams increases the concentrations of greenhouse gases in their waters, potentially exacerbating climate crisis. Our results also indicate that the scale at which human impacts occur has different effects on carbon dioxide and methane concentrations.

O bloqueio parcial das rotas onde atuam os herbicidas, com uso de baixas doses, pode ter implicações importantes, como a alteração do balanço de processos metabólicos nas plantas. Assim, foi conduzido no ano agrícola 2006/2007 um experimento em cana-soca

Lorde, de João Gilberto Noll: sob um olhar da teoria do imaginário
O foco do estudo é fazer uma leitura do romance Lorde (2004), de Noll, partindo da teoria do imaginário, por isso toma-se como base o teórico Gilbert Durand e, também, Gaston Bachelard.
