Worsaae, Katrine; Sterrer, Wolfgang; Kaul-Strehlow, Sabrina; Hay-Schmidt, Anders; Giribet, Gonzalo (Public Library of Science, 2012)The interstitial environment of marine sandy bottoms is a nutrient-rich, sheltered habitat whilst at the same time also often a turbulent, space-limited, and ecologically challenging environment dominated by meiofauna. The ... -
Anatomically modern Carboniferous harvestmen demonstrate early cladogenesis and stasis in Opiliones
Garwood, Russell J.; Dunlop, Jason A.; Giribet, Gonzalo; Sutton, Mark D. (Springer Nature, 2011)Harvestmen, the third most-diverse arachnid order, are an ancient group found on all continental landmasses, except Antarctica.

Aktipis, Stephanie W.; Boehm, Emily; Giribet, Gonzalo (Wiley-Blackwell, 2011)Fissurellids, commonly known as slit or keyhole limpets, are limpet-shaped gastropods that typically possess a hole, slit or notch in their bilaterally symmetrical shells and usually occur on rocky marine substrates. ... -
Application of magnetic resonance imaging in zoology
Ziegler, Alexander; Kunth, Martin; Mueller, Susanne; Bock, Christian; Pohmann, Rolf; Schröder, Leif; Faber, Cornelius; Giribet, Gonzalo (Springer Science + Business Media, 2011)Magnetic resonance imaging (MRI) is a noninvasive imaging technique that today constitutes one of the main pillars of preclinical and clinical imaging.

Are There True Cosmopolitan Sipunculan Worms? A Genetic Variation Study Within Phascolosoma perlucens (Sipuncula, Phascolosomatidae)
Kawauchi, Gisele Y.; Giribet, Gonzalo (Springer Science + Business Media, 2010)Phascolosoma perlucens is one of the most common intertidal sipunculan species and has been considered a circumtropical cosmopolitan taxon due to the presence of a long-lived larva. To verify whether P. perlucens is a true ... -
Assembling the spiralian tree of life
Giribet, Gonzalo; Dunn, Casey W.; Edgecombe, Gregory Donald; Hejnol, Andreas; Martindale, Mark Q.; Rouse, Greg W. (Oxford University Press, 2009)The advent of numerical methods for analyzing phylogenetic relationships, along with the study of morphology and molecular data, have driven our understanding of animal relationships for the past three decades. Within the ... -
Assessing the Molluscan Hypothesis Serialia (Monoplacophora + Polyplacophora) Using Novel Molecular Data
Wilson, Nerida G.; Rouse, Greg W.; Giribet, Gonzalo (Elsevier BV, 2010)A consensus on molluscan relationships has yet to be achieved, largely because of conflicting morphological and molecular hypotheses. Monoplacophora show marked seriality of ctenidia, atria, muscles and nephridia and this ... -
Biogeography in a Continental Island: Population Structure of the Relict Endemic Centipede Craterostigmus tasmanianus (Chilopoda, Craterostigmomorpha) in Tasmania Using 16S rRNA and COI
Velez, S.; Mesibov, R.; Giribet, Gonzalo (Oxford University Press (OUP), 2011)We used 16S ribosomal RNA (rRNA) and cytochrome c oxidase subunit I (COI) sequence data to investigate the population structure in the centipede Craterostigmus tasmanianus Pocock, 1902 (Chilopoda: Craterostigmomorpha: ... -
Brooding in Mecistocephalus togensis (Geophilomorpha: Placodesmata) and the Evolution of Parental Care in Centipedes (Chilopoda)
Edgecombe, Gregory Donald; Bonato, Lucio; Giribet, Gonzalo (Brill Academic Publishers, 2010)The only well-documented data on female brooding posture in the geophilomorph family Mecistocephalidae come from Dicellophilus carniolensis (C.L. Koch, 1847), in which the mother coils around the eggs and hatchlings with ... -
Canga Renatae, A New Genus and Species of Cyphophthalmi from Brazilian Amazon Caves (Opiliones: Neogoveidae)
DaSilva, Marcio Bernardino; Pinto-da-Rocha, Ricardo; Giribet, Gonzalo (Magnolia Press, 2010)A new genus and species of Cyphophthalmi, Canga renatae gen. nov., sp. nov., is described in the family Neogoveidae from a system of caves in the Serra de Carajás, Pará State, Brazil. Canga can be easily distinguished from ... -
Carboniferous Onychophora from Montceau‐les‐Mines, France, and onychophoran terrestrialization
Garwood, Russell J.; Edgecombe, Gregory D.; Charbonnier, Sylvain; Chabard, Dominique; Sotty, Daniel; Giribet, Gonzalo (John Wiley and Sons Inc., 2016)Abstract The geological age of the onychophoran crown‐group, and when the group came onto land, have been sources of debate. Although stem‐group Onychophora have been identified from as early as the Cambrian, the sparse ... -
Cementing mussels to oysters in the pteriomorphian tree: a phylogenomic approach
Lemer, Sarah; González, Vanessa L.; Bieler, Rüdiger; Giribet, Gonzalo (The Royal Society, 2016)Mussels (Mytilida) are a group of bivalves with ancient origins and some of the most important commercial shellfish worldwide. Mytilida consists of approximately 400 species found in various littoral and deep-sea environments, ... -

Riesgo, Ana; Da silva andrade, Sonia; Sharma, Prashant Pradeep; Novo, Marta; Perez-Porro, Alicia R.; Vahtera, Varpu; Gonzalez, Vanessa Liz; Kawauchi, Gisele Y.; Giribet, Gonzalo (BioMed Central, 2012)Introduction: Traditionally, genomic or transcriptomic data have been restricted to a few model or emerging model organisms, and to a handful of species of medical and/or environmental importance. Next-generation sequencing ... -
Comparative phylogeography of the centipedes Cryptops pictus and C. niuensis (Chilopoda) in New Caledonia, Fiji and Vanuatu
Murienne, Jérôme; Edgecombe, Gregory Donald; Giribet, Gonzalo (Springer Science + Business Media, 2011)The South Pacific is a biodiverse region of extreme evolutionary importance because it harbors ancient lineages and recent radiations.

A comprehensive molecular phylogeny of tardigrades-adding genes and taxa to a poorly resolved phylum-level phylogeny
Guil, Noemí; Giribet, Gonzalo (Wiley-Blackwell, 2011)Tardigrades constitute a phylum of miniaturized metazoans with ca. 1030 living species, a fossil record that probably dates back to the Cambrian, and physiological properties that allow them to live in almost any environment ... -
Current Understanding of Ecdysozoa and its Internal Phylogenetic Relationships
Giribet, Gonzalo; Edgecombe, Gregory Donald (Oxford University Press (OUP), 2017)Twenty years after its proposal, the monophyly of molting protostomes—Ecdysozoa—is a well-corroborated hypothesis, but the interrelationships of its major subclades are more ambiguous than is commonly appreciated. ... -
