In arid regions, excessive water use threatens agricultural sustainability and overall livelihoods. It is essential to minimize water consumption to address these issues. Date palm ( Phoenix dactylifera L.) is an emblematic crop of arid regions and a major water consumer. Tailoring current irrigation systems into new, water-efficient systems could ...

(…) Les oasis sont la combinaison, en milieu aride et désertique, d’une agglomération et d’une zone cultivée, ordinairement une palmeraie. Cette organisation n’est pas « naturelle » : elle n’existe pas sans les humains. Les oasis sont des espaces construits habilement, ingénieusement, entretenus et transformés sur le temps long par le fidèle labeur...
De l’emblématique Sahara aux déserts polaires, en passant par les déserts de Sonora, d’Atacama ou de Gobi, ce catalogue invite à un formidable voyage, au cœur d’une diversité de paysages insoupçonnés. Leur point commun ? L’aridité, les températures extrêmes, les vents violents… des conditions hors norme a priori hostiles à la vie. Et pourtant, il y...
In nature, microbes do not thrive in seclusion but are involved in complex interactions within-and between-microbial kingdoms. Among these, symbiotic associations with mycorrhizal fungi and nitrogen-fixing bacteria are namely known to improve plant health, while providing resources to benefit other microbial members. Yet, it is not clear how these ...
Hot deserts impose extreme conditions on plants growing in arid soils. Deserts are expanding due to climate change, thereby increasing the vulnerability of ecosystems and the need to preserve them. Arbuscular mycorrhizal fungi (AMF) improve plant fitness by enhancing plant water/nutrient uptake and stress tolerance. However, few studies have focuse...

The aim of the research, is to evaluate the suitability of some desert land in western Iraq for cultivation olive trees near water harvesting catchment. Semi details soil survey was conducted for (3492 donemes, eight pedons represented the soil great groups, (Alluvial desert soil, Typic calcids, Typic gypsed, Typic calcigypsids and Typic gypsicalci...
Abstract: Plants host diverse communities of fungi (the mycobiota), playing crucial roles in their development. The assembly processes of the mycobiota, however, remain poorly understood, in particular, whether it is transmitted by parents through the seeds (vertical transmission) or recruited in the environment (horizontal transmission). Here we a...
Les plantes vivent en interaction avec une multitude de microorganismes qui sont indispensables à leur développement. Parmi ces microorganismes, les champignons jouent un rôle central : certains forment les mycorhizes, des organes mixtes permettant entre autres d’assurer la nutrition des plantes. D’autres champignons, qualifiés d’endophytes, coloni...

Scavenging dynamics are influenced by many abiotic and biotic factors, but there is little knowledge of how scavengers respond to extreme weather events. As carrion is a major driver of the organisation and structure of food webs within ecological communities, understanding the response of scavengers to extreme weather events is critical in a world...
