Avian metapneumovirus (aMPV) is a highly contagious pathogen for broilers. Its epidemiological aspects remain poorly understood in Morocco. Given that, we carried out pilot seroepidemiological survey from December 2020 to June 2021 define aMPV seroprevalence Moroccan broiler flocks different bioclimatic zones (humid sub-humid, semi-arid, arid) during winter and spring. According these zones, 48...

The estimation of spatially-variable actual evapotranspiration (AET) is a critical challenge to regional water resources management. We propose a new remote sensing method, the Triangle Algorithm with Variable Edges (TAVE), to generate daily AET estimates based on satellite-derived land surface temperature and the vegetation index NDVI. The TAVE captures heterogeneity in AET across elevation zo...

Vegetation analysis in semi arid regions is in high demand and remote sensing applications are well established. In the field of change detection of Sahelian landscapes, one has to inventory states of vegetation at different recording dates. The Inland Niger Delta (Mali) is an azonal hydrographical landscape complex within the semi arid West African zone of the Sahel with water available throug...

Throughout many regions of the world, climate change has limited the availability of water for irrigating crops. Indeed, current models of climate change predict that arid and semi-arid zones will be places where precipitation will drastically decrease. In this context, plant root-associated fungi appear as a new strategy to improve ecophysiological performance and yield of crops under abiotic ...

Information about the spatial distribution of riparian vegetation, and the ecosystem services it provides, is required to prioritise the protection and restoration of riparian zones within watersheds. Large woody debris performs a range of fluvial geomorphic and ecological functions within streams. This paper describes a new technique for estimating how much large woody debris is provided by ri...

In the semi-arid rangelands of north central Kenya, the abundance of grasses has declined over recent decades. Concomitantly, the native succulent herb Sansevieria volkensii has greatly proliferated in many areas. Landscape structure has thus shifted from contiguous herbaceous cover to large, dense stands of S. volkensii with interpatches of bare or sparsely vegetated ground. Local pastoralists...

In arid and semi-arid rangelands, grazing as one of the natural or human induced processes has direct and indirect effects on structure and dynamics of plant community and ecosystems. A study was done to analyze the effects of grazing on plant species diversity and Plant Functional Types‘ (PFTs) diversity of arid and semi-arid rangelands. We analyzed plant richness and diversity data from 75 sa...
