1. Ecologia, doença e desenvolvimento na Amazônia dos anos 1950: Harald Sioli e a esquistossomose na Fordlândia
Resumo O artigo trata dos estudos do biólogo alemão Harald Sioli sobre a esquistossomose na região de Fordlândia, às margens do rio Tapajós, no Pará, realizados no início dos anos 1950, quando integrou a equipe do Instituto Agronômico do Norte (IAN). O IAN foi criado em 1939, no bojo de uma série de iniciativas destinadas a promover o desenvolvimen

2. Phytochemical and molluscicidal activity of Mikania glomerata Sprengel (Asteraceae) in different lifestages of Subulina octona (Mollusca, Subulinidade)
The objective of this work was to study the molluscicidal activity of aqueous extract of Mikania glomerata on the land snail Subulina octona and to assess the changes caused on the snail's fecundity, growth, hatchability and the offspring produced after exposure. Eggs, newly hatched and 30 day old snails were exposed to the sublethal concentration of M. glom

3. Re-characterization of the Red-lip Megalobulimus (Gastropoda: Strophocheilidae) from Peru with description of a new species
Megalobulimus K. Miller, 1878 is a genus of land snails that includes the largest living snails in the Neotropics. The main goal of this paper was to review all species of Megalobulimus that have a red lip, and which are distributed in Peru. We carried out a detailed description of their shells and soft parts, and conducted a multivariate analysis on their s

4. The influence of thymol+DMSO on survival, growth and reproduction of Bradybaena similaris (Mollusca: Bradybaenidae)
Bradybaena similaris (Férussac, 1821), commonly known as the Asian trampsnail, is a terrestrial snail native to Asia, introduced in other regions of the world. In Brazil, populations of this land snail are distributed from the state of Amapá in the North to Rio Grande do Sul in the South. This species acts as an intermediate host for parasites and is a dif

5. Monoamines in the pedal plexus of the land snail Megalobulimus oblongus (Gastropoda, Pulmonata)
In molluscs, the number of peripheral neurons far exceeds those found in the central nervous system. Although previous studies on the morphology of the peripheral nervous system exist, details of its organization remain unknown. Moreover, the foot of the terrestrial species has been studied less than that of the aquatic species. As this knowledge is essentia

6. SELEÇÃO ALIMENTAR E INFLUÊNCIA DE DIFERENTES DIETAS SOBRE O CRESCIMENTO, A REPRODUÇÃO E A SOBREVIVÊNCIA DE Bulimulus tenuissimus (d Orbigny, 1835) (MOLLUSCA, BULIMULIDAE) EM CONDIÇÕES DE LABORATÓRIO
Food selection includes features related to food, as taste and attractiveness, and may be related to the physiological conditions of the snail. Thus, food exerts great influence on the development of land snails, which can interfere in the reproductive activity of these animals. The objectives of this study were to verify the food selection and the influence

7. Electron spin resonance dating of shells from the sambaqui (shell mound) Capelinha, São Paulo, Brazil
Capelinha is a fluvial sambaqui (Brazilian Shell Mound) located in the Ribeira Valey in the State of São Paulo that is being studied. It is one of the oldest sambaquis located along a river dated so far in this region. The use of ESR to date other shells stimulated our group to apply this method to the Capelinha site. Shells from land snails (Megalobulimus

8. Verificação da potencialização do efeito cicatrizante do muco de caracóis do gênero Achatina promovida por dieta à base de Confrei (Symphytum officinale) / Investigation on the scar potential effect of mucus in the land snail Achatina fed with a diet based on Comfrey (Symphytum officinale)
Land snails are animals able to produce through glands located all over their body surface, a glycoprotein secretion called mucus. This mucus, within other roles, shows an antibacterial power that can help in the healing processes of wounds from several sources. Therefore, the aim of this study was to evaluate through macroscopic and histological techniques

9. Estudo comparativo do aparelho reprodutor do molusco Achatina fulica criado em cativeiro e asselvajado / Comparative study on the reproductive system in mollusk Achatina fulica raised in captivity and in the wild
120 land snails of the species Achatina fulica were arranged into four groups according to situation in which the first group was collected from the heliciculture site (LAB) at the Heliciário Experimental Professora Doutora Lor Cury FMVZ/USP and the other three groups, made up of wild individuals, were collected from a vegetable garden (DPE), a land lot

12. Heart rate and body weight alterations in juvenile specimens of the tropical land snail Megalobulimus sanctipauli during dormancy
The time course of heart rate and body weight alterations during the natural period of dormancy were determined in active feeding and dormant juvenile specimens of Megalobulimus sanctipauli. In both groups, heart rate markedly decreased during the first 40 days of dormancy, tending to stabilize thereafter. This time period coincided with the decrease in envi
