Use of climate smart agriculture technologies in West Africa peri-urban Sahel in Niger.

Climate change affects peri-urban agricultural systems. However, most studies on Climate-Smart Agriculture (CSA) often focused on climate-smart villages in the Sahel region. This study investigated peri-urban farming systems in West African Sahel cities.

Benthic exometabolites and their ecological significance on threatened Caribbean coral reefs.

Benthic organisms are the architectural framework supporting coral reef ecosystems, but their community composition has recently shifted on many reefs. Little is known about the metabolites released from these benthic organisms and how compositional shifts may influence other reef life, including prolific microorganisms. To investigate the metabolite composition of benthic exudates and their ecological significance for reef microbial communities, we harvested exudates from six species of Caribbean benthic organisms including stony corals, octocorals, and an invasive encrusting alga, and subjected these exudates to untargeted and targeted metabolomics approaches using liquid chromatography-mass spectrometry.

Impact of lung transplantation on diastolic dysfunction in recipients with pretransplant pulmonary hypertension.

Objective: Pulmonary hypertension can cause left ventricular diastolic dysfunction through ventricular interdependence. Moreover, diastolic dysfunction has been linked to adverse outcomes after lung transplant. The impact of lung transplant on diastolic dysfunction in recipients with pretransplant pulmonary hypertension is not defined.

Experimental dataset of sugarcane-cover crop intercropping trials to control weeds in Reunion Island.

Agroecological studies on sugarcane intercropping commonly generate complex datasets. A generic database (AEGIS - Agro-Ecological Global Information System) has been developed to facilitate the use of these datasets. The data described in this paper includes data from 8 experiments carried out on Reunion Island from 2012 to 2021 under three soil and climatic conditions to assess the capacity of cover crops in the sugarcane inter-row to control weed growth.

Chitin utilization by marine picocyanobacteria and the evolution of a planktonic lifestyle.

Marine picocyanobacteria and , the most abundant photosynthetic cells in the oceans, are generally thought to have a primarily single-celled and free-living lifestyle. However, while studying the ability of picocyanobacteria to supplement photosynthetic carbon fixation with the use of exogenous organic carbon, we found the widespread occurrence of genes for breaking down chitin, an abundant source of organic carbon that exists primarily as particles. We show that cells that encode a chitin degradation pathway display chitin degradation activity, attach to chitin particles, and show enhanced growth under low light conditions when exposed to chitosan, a partially deacetylated soluble form of chitin.
