UNIVERSIDAD NACIONAL MAYOR DE SAN MARCOS FACULTAD DE CIENCIAS BIOLÓGICAS UNIDAD DE POSTGRADO Filogeografía de Systrophia helicycloides: el reflejo de la dinámica del bosque lluvioso tropical en los genes 16S rRNA y COI de moluscos terrestres TESIS para optar el grado académico de Magíster en Biología Molecular AUTOR Pedro Eduardo Romero Condori ASESORA Rina L. Ramírez Mesias Lima – Perú 2010 "In the end, we will conserve only what we love; we will love only what we understand; and we will understand only what we are taught." (Baba Dioum, 1968) ii Para Katherine ¡buenas salenas! iii AGRADECIMIENTOS A Emma, por continuar apoyándome en esta aventura, día tras día, y a Pedro por acompañarme ahora desde un buen lugar, para toda la vida. A la Dra. Rina Ramírez, por enseñarme a buscar las preguntas, y encontrar las respuestas a este “misterio de los misterios”, tal como llamaba Charles Darwin al origen de las especies. Es una suerte tenerla como referente académico, y más aún como ejemplo de vida. Este trabajo pudo ser realizado gracias al apoyo de la Universidad Nacional Mayor de San Marcos a través del Vicerrectorado de Investigación y el Instituto de Ciencias Biológicas Antonio Raimondi que aprobaron los proyectos: “Evaluación de la biodiversidad de moluscos en la región del río Bajo Madre de Dios”, “Diversidad genética en la Amazonia: Polimorfismo del genoma mitocondrial de moluscos terrestres de la familia Systrophiidae” y “Biodiversidad de la Familia Systrophiidae (Mollusca, Gastropoda) en la cuenca del Río Los Amigos (Dpto.

ZooKeys 453: 1–17. doi: 10.3897/zookeys.453.8605 Abstract Two new species of the genus Zilchistrophia Weyrauch, 1960 are described from Eastern Ecuadorian rain forest: Zilchistrophia hilaryae sp. n. and Z. shiwiarorum sp. n. These two new species extend the distribu- tion of the genus considerably northwards, because congeners have been reported from Peru only. For the first time we present anatomical data (radula, buccal mass, morphology of the foot and the genital struc- ture) of Zilchistrophia species. According to these, the genus belongs to the family Scolodontidae, sub- family Scolodontinae (=“Systrophiini”). The previously assumed systematic relationship of Zilchistrophia with the Asian Corillidae and Plectopylidae based on the similarly looking palatal plicae is not supported.

Av. Benavides 5400, Surco. P.O. Box 18-131. Lima, Perú. Abstract: Peru is an ecologically diverse country, with 84 life zones in the Holdridge system and 18 ecological regions (including two marine). 1910 molluscan species have been recorded. The highest number corresponds to the sea: 570 gastropods, 370 bivalves, 36 cephalopods, 34 polyplacoforans, 3 monoplacophorans, 3 scaphopods and 2 aplacophorans (total 1018 species). The most diverse families are Veneridae (57spp.), Muricidae (47spp.), Collumbellidae (40 spp.) and Tellinidae (37 spp.). Biogeographically, 56 % of marine species are Panamic, 11 % Peruvian and the rest occurs in both provinces; 73 marine species are endemic to Peru. Land molluscs include 763 species, 2.54 % of the global estimate and 38 % of the South American esti- mate. The most biodiverse families are Bulimulidae with 424 spp., Clausiliidae with 75 spp. and Systrophiidae with 55 spp. In contrast, only 129 freshwater species have been reported, 35 endemics (mainly hydrobiids with 14 spp. The paper includes an overview of biogeography, ecology, use, history of research efforts and conser- vation; as well as indication of areas and species that are in greater need of study. -
Biodiversidad De Gasterópodos Terrestres (Mollusca) En El Parque Biológico Sierra De San Javier, Tucumán, Argentina
Biodiversidad de gasterópodos terrestres (Mollusca) en el Parque Biológico Sierra de San Javier, Tucumán, Argentina María José Miranda & María Gabriela Cuezzo CONICET-Facultad de Ciencias Naturales, Universidad Nacional de Tucumán, Miguel Lillo 251, 4000 Tucumán, Argentina; [email protected], [email protected] Recibido 08-III-2009. Corregido 12-III-2010. Aceptado 08-IV-2010. Abstract: Biodiversity of land gastropods (Mollusca) in Sierra de San Javier Park, Tucumán, Argentina. 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 per stations data matrix to analyze diversity patterns on qualitative and quantitative samples processed from 10x10m quadrates in altitudinal transects. Non parametric analysis (ICE, ACE, Chao 1 and Chao 2) were used to estimate the true diversity of the area, as well as the degree of undersampling and spatial aggregation of the data. Diversity was also calculated using Shannon, Simpson, Whittaker and Jaccard indices. The richness of the San Javier Park was estimated to be 32 species distributed into 13 families and 21 genera. From the total number of species collected, a single one belongs to Caenogastropoda, while the rest of the species are classified into Pulmonata Stylommatophora and Systellommatophora. The most representative family was the micromol- lusc Charopidae, while the most relatively abundant species was another micromollusc snail, Adelopoma tucma. Richness and diversity were slightly more elevated in dry forest areas of the Chacoan Ecoregion than in cloud forest areas of Yungas. -

[Taxonomy of terrestrial gastropods from the Quaternary of Argentina.] Revista Española de Paleontología, 26 (2), 101-133. ISSN 0213-6937. ABSTRACT This systematic review synthesizes our updated knowledge of 33 species and subspecies of Stylomatophoran gastropods, which belong to the genera Gastrocopta, Succinea, Radiodiscus, Retidiscus, Rotadiscus, Cecilioides, Austroborus, Megalobulimus, Bulimulus, Discoleus, Naesiotus, Plagiodontes, Spixia, Scolodonta, Miradiscops and Epiphragmophora. We provide published and unpublished records of the terrestrial molluscan taxa and a critical review, including data from the most important collections deposited in institutions from Argentina and abroad. All the taxa described have modern representatives; only two, Succinea rosariensis and Scolodonta argentina, still require confirmation regarding their taxonomic validity. The genera with confirmed older than Quaternary records are Austroborus, Megalobulimus, Radiodiscus, Rotadiscus and Succinea, which occur since the Paleoge- ne. Regarding the modern geographical distribution, well known records involve part of Argentina (Subtropical and Pampean Dominia of the Guayanian-Brazilian Subregion and the Central Dominion of the Andean Subre- gion, both in the Neotropical Region). -

E-mail: [email protected]; [email protected] Abstract: Systrophia argentina (Strobel, 1874) n. comb. is here re-described 150 years after its discovery. The specimens were found in the Argentine Precordillera (Quebrada San Isidro, Mendoza province, Argentina), at 2.000 m, near the typical locality of the species, here restricted to the Angostura or garganta (gullet) of Villa Vicencio and Casa de Piedra. It is the southernmost distribution of the genus. This snail has a shell of medium size, planispiral, with six whorls; radula with central plate tricuspid, and latero-marginal teeth aculeate, formula: 13 – C – 13; vagina short, spermathecal duct reaching the distal extreme of the vagina, near the atrium; penial sheath long, penis occupying most of the penial sheath, epiphallus with a retractor muscle adhered to its extreme, large and quadrangular gland attached to the penial sheath; atrium very short.
