Gustavo Darrigran,Ignacio Agudo-Padrón,Pedro Báez,Carlos Eduardo Belz,Franz Cardoso,Alvar Carranza,Gonzalo A. Collado,Modesto Correoso,Maria Gabriela Cuezzo,Alejandra Fabres,Diego Eduardo Gutiérrez Gregoric,Sergio Letelier,Sandra Ludwig,Maria Cristina Dreher Mansur,Guido Pastorino,Pablo E. Penchaszadeh,Carolina Peralta,Andrea Rebolledo,Alejandra Rumi,Sonia Barbosa dos Santos,Silvana C. Thiengo,Teofânia H. D. A. Vidigal,Cristina Damborenea +22 more
TL;DR: The first list of non-native mollusk species for South America, considering terrestrial, freshwater and marine environments, includes 86 NNMS distributed in 152 ecoregions of the 189 recognized for the South American continent.
Journal ArticleDOI
High-Throughput Sequencing Strategy for Microsatellite Genotyping Using Neotropical Fish as a Model
Juliana da Silva Martins Pimentel,Anderson Oliveira do Carmo,Izinara C Rosse,Ana Paula Vimieiro Martins,Sandra Ludwig,Susanne Facchin,Adriana Heloísa Pereira,Pedro Ferreira Pinto Brandão-Dias,Nazaré Lúcio de Abreu,Evanguedes Kalapothakis +9 more
TL;DR: A novel method for microsatellite genotyping using Illumina combinatorial barcoding that dispenses exhaustive PCR calibrations is presented, since non-specific amplicons can be eliminated by bioinformatics analyses.
Journal ArticleDOI
Influence of environmental variables on the growth and reproductive cycle of Crassostrea (Mollusca, Bivalvia) in Guaratuba Bay, Brazil
Roberto Montanhini Neto,Thayzi de Oliveira Zeni,Sandra Ludwig,Aline Horodesky,Marcus V. F Girotto,Gisele G. Castilho-Westphal,Antonio Ostrensky +6 more
TL;DR: Temperature, dissolved oxygen, and water transparency were the environmental factors that had the most influence on the reproductive cycle (e.g. gonadal development and spat capture) and on the growth of the oyster.
Journal ArticleDOI
High connectivity and migration potentiate the invasion of Limnoperna fortunei (Mollusca: Mytilidae) in South America
Sandra Ludwig,Eloisa H. R. Sari,Hugo Paixão,Lângia C. Montresor,Juliano M. Araújo,Cristiana F. A. Brito,Gustavo Darrigran,Almir R. Pepato,Teofânia H. D. A. Vidigal,Carlos Barreira Martinez +9 more
TL;DR: It is concluded that L. fortunei is a well-established invader and is still rapidly expanding in Brazil, and the Amazon hydrographic basin is under an alarming threat of invasion.
Journal ArticleDOI
Testing hypotheses on the origin and dispersion of Limnoperna fortunei (Bivalvia, Mytilidae) in the Iguassu River (Paraná, Brazil): molecular markers in larvae and adults
TL;DR: The characterization of genetic profile using larval stages of L. fortunei populations was satisfactory, and represents an important protocol for studying the population genetics of aquatic species with planktonic larval Stage.
