Article
Full-text available
The movement of species is among the most serious environmental threats of the new millennium, as the transplantation of species beyond their native or historical range has intensified in the last five decades. Traditionally, studies on bioinvasions have focused on species that have been introduced, deliberately or accidentally, to biogeographic re...

South America is a high biodiversity continent with five out of 13 countries considered megadiverse. Many major groups within this fauna exhibit high diversity, including non-marine molluscs. With at least 1401 known species, South American molluscs are seriously understudied. The aim of this paper is to review the conservation status of non-marine...

A new species of Succinea Draparnaud, 1801, S. puna sp. nov., from the Puna highlands in Catamarca Province, Argentina, is described. Seventeen water bodies were surveyed in the Puna ecoregion of Catamarca, with gastropods being found only at two localities, El Peñón and Guanchín River. We explored the morphological features of shells, reproductive...

Background Stephadiscus lyratus (Couthouy in Gould, 1846), an endemic Charopidae from southern South America, was described from few dry shells. The distribution of this species is known on scattering occurrences, mainly from material deposited in museum collections. We provide here new information on anatomy, habitat, and microhabitat preferences...

The classification of terrestrial sundial snails has a long and contentious history; they have been diversely classified in Camaenidae, Pleurodontidae, Polygyridae, and also in their own family, Solaropsidae. Two genera have been recently removed from Solaropsidae (Polygyratia Gray, 1847 and Ridleya Ancey, 1901), but the status of its 3 remaining g...

Twenty-five sub-ecoregions make Argentina from southern South America a favored area to study the mutual correspondence between environments and biodiversity. Unfortunately, efforts devoted to study these environments are unbalanced, with the subtropical dry forests less studied than the tropical and subtropical humid ones. Since the limits of ecor...

Non-native species have been introduced at escalating rates during the last decades, mainly due to the dispersion generated by the increasing trade and transport worldwide. Mollusks, the second largest metazoan phylum in terms of species richness, are no exception to this pattern, but, to date, a comprehensive synthesis of non-native mollusk specie...

Chapter
An updated taxonomic review of Mollusca from the Neotropical regions is presented in this chapter. Dichotomous identification keys to the lowest justifiable taxonomic level based on the most recent literature are provided. These are coupled with the material preparation methods, defined relevant morphological terms, and current limitations in our k...

Four of the 43 genera of South American Leptophlebiidae are dipterous. A previous phylogenetic hypothesis supported that clade Askola+Hagenulopsis, and that Bessierus+Perissophlebiodes, are sister groups of the Farrodes complex. Adults of Bessierus and Perissophlebiodes were not known but posteriorly Perissophlebiodes male imago was described. Here...

Background Land gastropods of the Dry Chaco merit special attention because they comprise a highly diverse but barely studied group. Clessinia Doering, 1875 are typical inhabitants of this ecoregion. The inclusion of their distribution areas into Spixia range, their shell shape similarities, and a former molecular study raised doubts on the monophy...

Studies related to land mollusk diversity in tropical and subtropical forests are scarce. To assess this, a study on land snail diversity of subtropical cloudforest (Yungas) and dry forest (Chaco) areas of Sierra de San Javier Park, Tucumán, Argentina, was carried out. Taxonomic identifications were performed to species level and built a species pe...

We redescribe Drepanostomella tucma Hylton Scott, 1948 and discuss the possible affinities of the genus. This is the first published report on the anatomy of a species of the genus Drepanostomella Bourguignat, 1889 since this taxon was previously known only on the basis of its shell morphology and radula. Drepanostomella was traditionally classifie...

A new approach for biogeography to find patterns of sympatry, based on network analysis, is proposed. Biogeographic analysis focuses basically on sympatry patterns of species. Sympatry is a network (= relational) datum, but it has never been analyzed before using relational tools such as Network Analysis. Our approach to biogeographic analysis cons...

The ultrastructure of the sperm of Epiphragmophora tucumanensis (Doering), a pulmonate land snail belonging to the family Xanthonychidae, was examined. The results showed that this spermatozoon presents a similar morphology to the other advanced stylommatophoran sperm described. The most peculiar characteristic is the form of the nucleus, which is...

Se propone realizar un análisis biogeográfico de especies de invertebrados con requerimientos ecológicos disímiles (gasterópodos terrestres y acuáticos versus otros invertebrados) de la Argentina a fin de determinar Unidades de Co-distribución (UC), candidatas a áreas de endemismo. Asimismo, se incursionará en el estudio de la compatibilidad de patrones de grupos acuáticos y terrestres, nivel de endemismos y diversidad filogenética dentro de las UC identificadas. Su correspondencia con otras áreas establecidas sobre la base de otros criterios de diversidad (áreas protegidas y esquemas de regionalización) será también explorada. Se propone ahondar en estudios filogenéticos de ciertos taxones tal como la filogenia de Epiphragmophoridae (Gastropoda) de Argentina a fin de testar junto a las otras filogenias de grupos no relacionados ya existentes, si las UC identificadas con el análisis biogeográfico de redes remiten a un componente histórico, a condiciones ecológicas o una combinación de ambas. Se trabajará con el método NAM (Network Analysis Method) para detectar patrones en las distribuciones de los organismos a partir de la evidencia directa (coordenadas geográficas de registros puntuales) de las distintas especies en estudio. La diversidad filogenética de las UCs obtenidas se analizarán mediante el procedimiento de cálculo sugerido por Faith. La integración filogenética y biogeográfica se efectuará con el desarrollo de una nueva metodología cuantificándose en función de los conceptos de homofilia y heterofilia en redes.
