Investigations in commonness and rarity: A comparative analysis of co-occurring, congeneric Mexican trees
(2001)
Population size distributions were examined for 12 species of trees co-occurring at Chamela Biological Station in Jalisco, Mexico. Species had been selected as congeneric pairs and trios similar in gross morphology and ...
Estudo da formação de domínios em membranas modelos induzidos por peptídeos antimicrobianos e sua ação interfacial
(Universidade Estadual Paulista (Unesp), 2016-05-13)
Peptídeos antimicrobianos agem diretamente na matriz lipídica da membrana celular perturbando o empacotamento lipídico, criando tensões elásticas e desequilíbrio de massa, que são relaxados pela formação de poros ou defeitos ...

Effects of young cladodes on the gas exchange of basal cladodes of Opuntia ficus-indica (Cactaceae) under wet and dry conditions
(2005)
Crassulacean acid metabolism (CAM) plants, such as the cultivated Opuntia ficus-indica, are resistant to drought, but their responses can be affected by development of new organs, such as young, developing cladodes. The ...
