Biorremediación del agua recirculante en cultivo de camarón blanco utilizando microbiota autóctona del mangle rojo

open access: yesRevista del Instituto de Investigación de la Facultad de Minas, Metalurgia y Ciencias Geográficas, 2018
La actividad acuícola en el cultivo del camarón blanco utilizando agua recirculante deteriora la calidad del agua por la acción hidrodinámica aguametabolitos- materia orgánica, que generan impactos negativos en la producción del crustáceo. El objetivo de

Data gaps and heterogeneity limit our understanding of human–wildlife interactions: A continental study of Andean bears

open access: yesPeople and Nature, EarlyView.
Abstract The expansion and intensification of human activities have increased interactions between people and wildlife. Interactions involving bears and other large carnivores are complex and can lead to conflicts. Promoting positive coexistence requires managing information, which is not always available.

Forest Guardians: The Role of Dense Forests and Water Networks in Supporting Lowland Tapir (Tapirus terrestris) Populations in the Orinoquia Region of Colombia

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
Our study reveals that lowland tapir (Tapirus terrestris ) occupancy in Colombia's Orinoquia region is strongly influenced by dense forests and proximity to water bodies, while anthropogenic factors such as pastures and road networks negatively impact their presence.

Water‐saving strategies in rice farming entail cascading effects in prey–predator interactions across ecosystem boundaries

open access: yesJournal of Applied Ecology, Volume 62, Issue 9, Page 2273-2282, September 2025.
These results show that introducing multiple drainage periods in rice fields (i.e. AWD) indirectly hampers terrestrial spider reproduction through limiting the emergence of potential preys from the aquatic to terrestrial boundaries. MSD resulted in a more conciliatory strategy as it largely reduces methane emissions and does not affect predator–prey ...

Geoviolence: Climate Injustice, Labour Migration, and Intimacy

open access: yesAntipode, Volume 57, Issue 5, Page 1914-1932, September 2025.
Abstract In the context of anthropogenic climate change, it has become increasingly imperative to examine the socio‐ecological consequences of human‐made environmental degradation as a form of violence. I advance the term “geoviolence” to refer to human actions that increase suffering through the generation, exacerbation, or instrumentalisation of ...

Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth

open access: yesNew Phytologist, Volume 247, Issue 5, Page 2042-2048, September 2025.
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...
