1. Redescription of Ventania avellanedae (Stylommatophora: Odontostomidae), a land snail endemic to the Ventania Mountain System, Argentina
ABSTRACT Although the presence of apertural folds and lamellae is the most recognizable character of the Odontostomidae, some species lack them, mostly in Anctus Martens, 1860, Bahiensis Jousseaume, 1877 and Moricandia Pilsbry & Vanatta, 1898. Eudioptus avellanedae Doering, 1881 - a slender odontostomid species that lacks even the slightest trace of folds or

2. The exotic jumping snail Ovachlamys fulgens (Gude, 1900) (Gastropoda: Helicarionidae) in urban areas of the Upper-Paraná Atlantic Forest
ABSTRACT The exotic land gastropod Ovachlamys fulgens (Gude, 1900), aka the jumping snail, was registered in Eldorado city, Misiones province, constituting the first documented record of that species in Argentina-and for all of South America as well. Identities of the individuals were confirmed through morphological examination, and by a DNA sequencing of th

3. Population dynamics of Megalobulimus paranaguensis (Gastropoda: Pulmonata) in the southeast coast of Brazil
ABSTRACT. The population dynamics of Megalobulimus paranaguensis (Pilsbry & Ihering, 1900), a large and long-lived land gastropod from Brazil's Southeast (Atlantic Forest) was studied between 2006 and 2009, at an urban park in the city of Santos, state of São Paulo. The study included biometry, weighing, and marking and recapture of adult individuals. The v

4. 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

5. 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

6. 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

7. Vascular supply of the central nervous system of the land snail Megalobulimus oblongus (Gastropoda, Pulmonata)
The vascularization of the central nervous system of the snail Megalobulimus oblongus was studied by injection of carmine-gelatin solution into the arterial system and using a histochemical technique for the detection of alkaline phosphatase. The central nervous system of M. oblongus is irrigated by the anterior aorta, from which a series of small branches e

8. 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

9. LIFE HISTORY OF Bulimulus tenuissimus (D Orbigny, 1835) (MOLLUSCA, Bulimulidae): CHANGES ON THE ENERGETIC CONTENT ACORDINGING TO AGE AND SEASONALITY / HISTÓRIA DE VIDA DE Bulimulus tenuissimus (D ORBIGNY, 1835) (MOLLUSCA, BULIMULIDAE): VARIAÇÃO NO CONTEÚDO DOS SUBSTRATOS ENERGÉTICOS DE ACORDO COM A IDADE E SAZONALIDADE
Apesar da diversidade e importância os moluscos terrestres têm sido pouco estudados, principalmente as espécies da malacofauna brasileira como é o caso de Bulimulus tenuissimus. Assim, objetivou-se com esse trabalho descrever a história de vida dessa espécie, através da avaliação do crescimento, reprodução e longevidade. Avaliou-se também a influ

10. Efeito da anoxia e da reoxigenação sobre o metabolismo do sistema nervoso central do caracol terrestre megalobulimus abbreviatus / Effects of anoxia and reoxygenation on the metabolism of the central nervous system of the land snail Megalobulimus Abbreviatus
Animais tolerantes à anoxia são essenciais para o estudo dos mecanismos capazes de proteger tecidos sensíveis, como o coração e o sistema nervoso, de períodos de reduzida disponibilidade de oxigênio. Por ser um animal terrestre tolerante às reduções ambientais na tensão de oxigênio, o caracol Megalobulimus abbreviatus representa um excelente mode

11. 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
