  abstract = {{T}he project entitled "{S}tudy of montane ecosystems in the {M}alagasy region" ({RCP} 225/{CNRS}, directed by {R}enaud {P}aulian) aimed to elucidate the general features of these ecosystems and the origin of their constituent elements, and to test the validity of the {H}igh {M}ountain {D}omain proposed by {H}umbert in 1951. {F}rom 1970 to 1973, three expeditions (to the {A}ndringitra, {A}nosy, {A}nkaratra, itremo, libity and {M}arojejy massifs) provided informations to characterize the ecology of these particular environments and to analyse systematically certain groups well-known for their biogeographic interest. {T}he altitudinal succession of plant formations, defined by physiognomic and structural criteria, were detailed for each massif. {T}he highest belt, characterized by an ericoid bush and related associations, does not correspond to the {H}igh {M}ountain formation of {E}ast {A}frica. {D}ata on several faunal groups, including invertebrates ({H}exapoda: {C}ollembola and {D}ermaptera), indicate a disjunction between the northern montane massifs ({T}saratanana and marojejy) and the remainder in the {C}enter and {S}outh; several floristic groups ({P}andanaceae, {A}raliaceae and {A}steraceae) are currently being analyzed in a similar manner. {M}adagascar's {H}igh {M}ountain {D}omain is an ecological reality, but it can not be defined floristically, as each massif represents a separate phyrogeographic entity of the island's {C}entral {D}omain. {F}aunal groups with limited mobility broadly indicate a trophic and bioclimatic dependence (buffer effect of the intra-forest climate) with regard to vegetation belt, but can respond to local microclimates by a shift at the limits of their ranges.},
