Evidence of non-drilling predation by a naticid gastropod in bivalves on Camocim Beach, Ceará, northeastern Brazil

Spatial Variation of Naticid Gastropod Predation in the Eocene of North-America

Environmental isolates of Burkholderia pseudomallei in Ceará State, northeastern Brazil.

Melioidosis has been considered an emerging disease in Brazil since the first cases were reported to occur in the northeast region. This study investigated two municipalities in Ceará state where melioidosis cases have been confirmed to occur. Burkholderia pseudomallei was isolated in 26 (4.3%) of 600 samples in the dry and rainy seasons.

Effectiveness of nutrition centers in Ceará state, northeastern Brazil.

Childhood malnutrition has been a major, long-standing health concern in northeastern Brazil. In response, during 1992-1994, the state government of Ceará, with financial support from the World Bank, established 34 new nutrition centers. During 1996 an evaluation of the centers was conducted to determine their effectiveness in treating children with malnutrition and to identify weaknesses in th...

Taphonomic Bias in Analyses of Drilling Predation: Effects of Gastropod Drill Holes on Bivalve Shell Strength

T h e proportion of bivalve shells with drill holes i n fossil assemblages is commonly used as a measure of the intensity of predation by drilling gastropods. Previous studies have assumed that drilled and undrilled bivalve shells have equal preseruat ion wotentials. W e tested this assumption by measuring the mechanical strength of drilled and undrilled valves of the Recent bivalve Mulinia lat...
