  abstract = {{U}nderstanding processes that explain phytolith assemblages and their concentration in the soil and sediments is essential to interpret long-term ecological changes. {T}he present study shows modern phytolith assemblages and their relationship with the vegetation cover in the {C}aatinga biome, state of {C}ear ' a, northeastern {B}razil. {W}e collected recent samples from soil surfaces, in 2015, in three different vegetation covers (open shrubby {C}aatinga, dense shrubby {C}aatinga, and {C}aatinga forest vegetation) and from two cores with recently deposited sediments, in {M}assape (74 cm depth, 55 years old) and {V}arjota (50 cm depth, 58 years old). {A}fter phytolith extraction, we studied twelve samples from soils and thirteen samples from cores. {T}he counting revealed 26 different phytolith types with some differences in the concentration of silica bodies in different vegetation covers. {P}hytoliths were well preserved and could be related to the presence of plants, such as {P}oaceae (subfamily {P}anicoideae and {C}hloridoideae), {A}recaceae and {C}yperaceae. {I}n the two cores, the most common type was globular echinate and could be associated with the presence of palms in the riparian forest and open landscapes in the surroundings. {I}n soil surfaces samples, the saddle was the most frequent type. {W}e found a high concentration of globular granulate around {A}iuaba {E}cological {S}tation, which harbors a preserved {C}aatinga area. {F}inally, we observed a good match between vegetation cover and the phytolith assemblages collected in soils and reservoirs.},
