Genetic Diversity of the Cichlid Andinoacara latifrons (Steindachner, 1878) as a Conservation Strategy in Different Colombian Basins

open access: yesFrontiers in Genetics, 2020
Cichlids constitute a diverse monophyletic group that have developed adaptive strategies to thrive in diverse environments. Andinoacara represents an example of diversification on the South American Andean uplift, providing a key model for understanding ...

The Plant‐to‐Plant Circular Strategy: Coupling Photodegradation and Phytoremediation With Plant‐Based Nanomaterials for Plastic Degradation

open access: yesAdvanced Science, EarlyView.
Plant‐based nanomaterials derived from alfalfa serve as dual‐function catalysts, coupling photodegradation and phytoremediation to degrade polyethylene under UV‐A light and in soil. The nanomaterials work synergistically with alfalfa and soil microbes, achieving efficient plastic breakdown without trophic transfer.

How Multiple Streams Influence Agenda‐Setting for Water Reuse in Swiss Substates

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT As climate change creates significant challenges for both the environment and society, potential mitigation and adaptation solutions are widely discussed. Yet, neither challenges nor their potential solutions automatically reach the political agenda or lead to a policy decision.

Use of high-intensity data to define large river management units: A case study on the lower Waikato River, New Zealand [PDF]

open access: yes, 2014
The importance of environmental heterogeneity in lotic ecosystems is well recognised in river management, and continues to underpin studies of hierarchical patch dynamics, geomorphology and landscape ecology. We evaluated how physical characteristics and

Acute effects of anti‐seizure medications on network level dynamics: A systematic comparison using multielectrode arrays

open access: yesEpilepsia, EarlyView.
Abstract Objective A multi‐electrode array (MEA) is a powerful extracellular recording technique for long‐term monitoring of neuronal network activity. In recent years, MEA‐based assays have been applied increasingly to evaluate drug efficacy and neurotoxicity, including the assessment of anti‐seizure medications (ASMs). However, systematic comparisons

El río Magdalena como guardián de memoria y árbol de agua de Colombia en Los escogidos y Grávido río

open access: yesRecherches
Colombia is woven with rivers, but one vertebral river, the Magdalena, is imagined as a river of death on a social and environmental level. This article features reimaginings of the Magdalena in literature: as a guardian of memory of war, beyond a mass ...
