RESUMO

(Composi&#xE7;&#xE3;o, espectro biol&#xF3;gico e s&#xED;ndromes de dispers&#xE3;o da vegeta&#xE7;&#xE3;o de um inselbergue no dom&#xED;nio da
caatinga, Cear&#xE1;) Comunidades de plantas sobre afloramentos rochosos no semi-&#xE1;rido brasileiro ainda s&#xE3;o
pouco conhecidas para a ci&#xEA;ncia. O munic&#xED;pio de Quixad&#xE1;, no semi-&#xE1;rido cearense, destaca-se pela grande
concentra&#xE7;&#xE3;o de eleva&#xE7;&#xF5;es de ilhas rochosas. Este estudo tem por objetivos levantar e analisar a composi&#xE7;&#xE3;o,
o espectro biol&#xF3;gico e as s&#xED;ndromes de dispers&#xE3;o das esp&#xE9;cies que ocorrem em um inselbergue no munic&#xED;pio
de Quixad&#xE1;, Cear&#xE1;, e a similaridade flor&#xED;stica deste com as esp&#xE9;cies da vegeta&#xE7;&#xE3;o circundante. Em 2000, foram
realizadas coletas mensais de esp&#xE9;cies e classificadas quanto &#xE0;s formas de vida e s&#xED;ndromes de dispers&#xE3;o em
uma &#xE1;rea situada a 4o57&#x2019;S e 39o 01&#x2019;W e 270 m de altitude. A similaridade da flora com o entorno foi analisada
atrav&#xE9;s do &#xED;ndice de Jaccard. Foram inventariadas 77 esp&#xE9;cies, 66 g&#xEA;neros e 36 fam&#xED;lias. As porcentagens do
espectro biol&#xF3;gico foram: ter&#xF3;fitos (44,2), faner&#xF3;fitos (24,7), cam&#xE9;fitos (14,6), hemicript&#xF3;fitos (13,4), ge&#xF3;fitos

similaridade com flora do entorno foi de 13% (21 esp&#xE9;cies), demonstrando que a caatinga local &#xE9; a potencial
fonte de prop&#xE1;gulos. Os ter&#xF3;fitos s&#xE3;o as formas de vida dominante nos inselbergues de regi&#xF5;es &#xE1;ridas e semi&#xE1;ridas,

ABSTRACT

(Composition, biological spectrum and dispersal syndromes of the vegetation of an Inselberg in the domain
of caatinga, Cear&#xE1;) Plant communities on rock outcrops in brazilian semiarid are still largely unknown to
science. The country Quixad&#xE1;, in the semiarid of the state of Cear&#xE1;, is distinguished by the great concentration
of rock outcrops. This study aims to know the composition, the life-form and the strategies of dispersal of the
species in an inselberg the country of Quixad&#xE1; and the similarity with surrounding caatinga. In the 2000 year,
monthly collects of the flora were carried out and the life-forms and dispersal syndromes were classified in an
area situated on 4&#xB0; 57' S and 39&#xB0; 01' W, 270 m. a.s.l. The similarity of the flora of the surrounding was analyzed
through the Jaccard index. Seventy-seven species, 66 genera and 36 families had been inventoried. The
percentages of the life-form spectrum and the dispersal spectrum represented were: therophytes (44,2),
phanerophytes (24,7), chamaephytes (14,6), hemicryptophytes (13,4), geophytes (2,6), aerophytes (1,2) and
anemocoric (49), autocoric (35) and zoocoric (16). The similarity with the flora of the caatinga surrounding
was 13% (21 species), what it demonstrated that the vegetation surrounding is the main source of propagules.
The therophytes are the dominant life-form in inselbergs of semi-arid regions, whose flora also is predominantly
dispersed for abiotic factors, mainly the wind. This study confirms the expected patterns about dispersal and
life-form spectrum of the arid and semiarid vegetation.
