| Résumé : |
The chotts in Algeria are temporary salt lakes recognized as important wintering sites of water
birds but neglected in terms of the diversity of the insects living on their banks. Around a
chott in the wetland complex in the high plains near Constantine (eastern Algeria), more than
half of the species of plants are annuals that dry out in summer, a situation that prompted us to
sample the vegetation in spring over a period of two years. Three zones were identifi ed based
on an analysis of the vegetation and measurements of the salt content of the soils. Surveys
carried out at monthly intervals over the course of a year revealed temporal and spatial
variations in biodiversity and abundance of grasshoppers. The inner zone is colonized by
halophilic plants and only one grasshopper species (Dericorys millierei) occurs there
throughout the year. Two polyphagous species of Calliptamus, which can feed on halophilic
plants migrate from adjacent areas into the inner zone in August to feed on the plants growing
there. The other species of grasshoppers remain in outer zones as they are unable to feed on
halophilic plants. The greatest abundance of grasshoppers from August to winter was
recorded in the inner zone and in spring and early summer in the outer zones. The dependence
of D. millierei on bushes of Amaranthaceae and its moderate fl ight ability, features of the
family Dericorytidae, limit this species ability to colonize neighbouring chotts. |
