The LMEB has some megaphanerophytes, more microphanerophytes, and conspicuously less hemicryptophytes
and epiphytes than the other two forests.
In this heterogeneous environment the floristic spectra change in the different habitats, where the grasslands had a higher percentage of hemicryptophytes
followed by chamaephytes; and the scrub boundaries are more phanerophytic (Caiafa & Silva, 2005; Conceicao & Pirani, 2007).
The life form spectra showed 31 (39.74%) therophytes, 17 (21.79%) megaphanerophytes, 12 (15.38%) cryptophytes, 11 (14.10%) nanophanerophytes, 5 (6.41%) hemicryptophytes
and 2 (2.56%) chamaephytes (Table 2, Fig.
Vascular plants of the island mainly include therophytes (~ 62 %), hemicryptophytes
(~20 %), geophytes (~9 %), chamaephytes (~5.5 %), nanophanerophytes (~2.3 %) and phanerophytes (~1.8 %).
The number of species in the studied remnants ranged from 18 (F8) to 81 (F10), with the predominance of hemicryptophytes
, followed by epiphytes (Table 2).
Hafir: Th > Ch > Ge > He > Ph; Sebdou: Th > Ch > Ge > He, Ph; Tlemcen: Th > Ch > He > Ge, Ph; Sidi Djilali: Th > Ch > He > Ph > Ge (Th: therophytes, Ch: chamaephytes; He: hemicryptophytes
; Ph: phanerophytes; Ge: geophytes).
The Irano-Turanian region that has low rainfall and long dry season is characterized by the dominance of hemicryptophytes
and chamaephytes (Djamali et al., 2012).
Others are Hemicryptophytes
(24%), Phanerophytes (12%), and Geophytes (10%), that is, 54% of Iranian-Toranian plant.
The life form spectrum of the vascular flora indicates the predominance of therophytes (52%), with hemicryptophytes
(15%) and phanerophytes (10%) (Figure 4).
The life form spectrum of the recorded species showed the prevalence of theorphytes (37%) followed by chamaephytes (32%), geeophytes (13%), hemicryptophytes
(10%) and Phanerophytes (8%).
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.
The proportions of herbaceous-subshrub/shrub-arboreal (epiphytes, succulents, chamaephytes, hemicryptophytes
, and therophytes /phanerophytes) species were calculated for each of the vegetation types, for cerrado-caatinga transition, and for the different cerrado physiognomies.
