This research assesses the role of small-scale managed aquifer recharge (s-MAR) in the attenuation of meteorological drought propagation. Human activity can induce or aggravate the drought cascade, threatening groundwater-dependent communities. In Oaxaca, Mexico, people have united to implement s-MAR techniques, using low-tech, ecologically sound, and low-cost structures to address water scarcity and drought. Efforts began sho...

Irrigated agriculture provides 40% of the world's crop‐based foods but often with a negative impact on the environment. It is important to recognize that in addition to providing food and fibre, irrigation and controlled drainage systems can be optimized to provide additional ecosystem services and mitigate climate change by using resources in a more efficient way. Contemporary case studies were identified from around the worl...

Holosporales are an alphaproteobacterial order engaging in obligate and complex associations with eukaryotes, in particular protists. The functional and evolutionary features of those interactions are still largely undisclosed. Here, we sequenced the genomes of two members of the species Bealeia paramacronuclearis ( Holosporales , Holosporaceae ) intracellularly associated with the ciliate protist Paramecium , which resulted i...

Rainfed agriculture, which is dominant in sub‐Saharan Africa, remains vulnerable to the impacts of climate change. In this framework, flood‐based farming systems (FBFS) enable the use of floodwater as an opportunity for crop production. FBFS have received much attention recently; however, there is limited guidance on how they can be promoted effectively in rural areas. To do so and to support the adoption of appropriate system...

The subclass Peniculia (Oligohymenophorea, Intramacronucleata) is one of the most known groups of the phylum Ciliophora, being composed by very notorious representatives, such as Paramecium and Frontonia . Nevertheless, phylogenetic relationships among genera within this subclass are still far from being resolved. Moreover, for several members of the group the characterization by molecular markers is still lacking, such as for...

Summary Members of the bacterial order Rickettsiales are obligatorily associated with a wide range of eukaryotic hosts. Their evolutionary trajectories, in particular concerning the origin of shared or differential traits among distant sub‐lineages, are still poorly understood. Here, we characterized a novel Rickettsiales bacterium associated with the ciliate Paramecium tredecaurelia and phylogenetically related to the Rickett...
