Du cote negatif s'installent les taxons le plus contributifs, de nature biologique variees: geophyte
(Arisarum vulgare -1.69), hemicryptophyte (Sedum acre -1.54) associes aux therophytes (Aegilops triuncialis -2.04, Trifolium stellatum -1.69) indiquant ainsi un gradient croissant pre-foret allant du cote positif au cote negatif.
Decoupling of reproduction and growth: an unusual pattern in the life cycle of the Mediterranean geophyte
Observations on the feeding habits of the Indian crested porcupine (Hystrix indica) and the distribution of some hemicryptophytes and geophytes
in the Negev Desert Highlands.

Temperature requirements for seed germination and seedling development determine riming of seedling emergence of three monocotyledonous temperate forest spring geophytes
; from basic science to sustainable production.
Out of which 13.33% were megaphanerophytes, 20.00% were nanophanerophytes and Chameophytes each, 33.33% were hemicryptophytes and 6.67% were geophytes
and therophytes each.
Life histories of desert geophytes
--the demographic consequences of reproductive biomass partitioning patterns.
Many plants in the Cape Floral Region produce edible geophytes
, underground energy-storage organs that swell with carbohydrates at certain times of the year.
Life form analysis of these two sites indicated the presence of therophytes (Th), chamaephytes (Ch), hemicryptophytes (H), geophytes
(G) and phenerophytes (Ph).
Semi-desert habitats are scattered with perennial shrubs and geophytes
. In some wadis eucalyptus and acacia trees were planted in recent decades.
