    Rôle de la côte Atlantique marocaine dans l'hivernage des limicoles (<em>Aves</em>, <em>Charadrii</em>)

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    An analysis of the distribution of wintering waders in Morocco showed that 91% were found on the Atlantic coast, where their preferred habitats (sandy beaches, mudflats, marshlands) are best represented. Waders in Morocco can be grouped into three categories based...
  2. POSITIVITY METHODS FOR DICHOTOMY OF LINEAR SKEW-PRODUCT FLOWS ON HILBERT SPACES

    POSITIVITY METHODS FOR DICHOTOMY OF LINEAR SKEW-PRODUCT FLOWS ON HILBERT SPACES

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    In [Na-Rh] we developed a method based on positivity in order to characterize the stability of the evolution family corresponding to the nonautonomous Cauchy problem in Hilbert spaces. This method is extended to the study of hyperbolicity of linear skew-products...

    Alarming decline and range reduction of the highly threatened Great Bustard <em>Otis tarda</em> in Morocco

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    A Great Bustard Otis tarda survey carried out in spring 2015 in Morocco confirmed the decline of this highly endangered population. Bustards were only seen at two of the seven leks occupied ten years ago. The total number of birds...
