MODELING OF THREE-DIMENSIONAL WETTING PATTERNS UNDER SUBSURFACE DRIP IRRIGATION
Mağallaẗ Al-kūfaẗ Al-handasiyyaẗThe drip irrigation method is one of the highly efficient methods to provide irrigation water in arid and semi-arid areas, and subsurface drip irrigation is the best in terms of reducing evaporation from the soil surface. The study aimed to follow up the

Classifying avian drinking behaviour: ecological insights and implications in a changing world
Biological Reviews, EarlyView.ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome
Biological Reviews, EarlyView.ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Flow Characteristics in Vertical Shaft Spillway with Varied Inlet Shapes and Submergence States
Tikrit Journal of Engineering SciencesA spillway is an essential hydraulic structure that discharges excessive water, especially during floods from upstream to downstream of the dam. A shaft spillway is sometimes used when a limited area is available. This study used four physical models of

Biological Reviews, EarlyView.ABSTRACT One of the major subfields of chemical ecology is the study of toxins and how they mediate interactions between organisms. Toxins produced by harmful algae (phycotoxins) impact a wide variety of organisms connected to the marine food web. Significant research efforts have thus aimed to identify the ecological and evolutionary drivers behind ...
