Epibiotic barnacles of sea turtles as indicators of habitat use and fishery interactions: An analysis of juvenile loggerhead sea turtles, Caretta car…
2019
Abstract Sea turtles exploit a variety of habitats during their lifetime and are thus exposed to a number of anthropogenic threats, including interaction with fisheries. Mitigating this impact requires determining patterns of habitat use by turtles, which largely relies on data from marked individuals. We investigated the use of epibiotic barnacles as a cost-effective method to ascertain habitat use by sea turtles, choosing the juvenile loggerhead sea turtles (Caretta caretta) in the western Mediterranean as a model. A total of 200 turtles collected in the central Spanish Mediterranean between 1990 and 2017 were examined for epibionts: 25% were accidentally captured by pelagic longliners, 1…
Epibiontes en juveniles de tortugas carey Eretmochelys imbricata varadas en la costa del Departamento de Rocha, Uruguay
2016
The hawksbill turtle (Eretmochelys imbricata) is the most threatened sea turtle species in the world. An important aspect of the biology of sea turtles is the study of colonizing fauna, i.e., their epibiota. The aim of this study is a taxonomic determination on the epibiota found on 4 hawksbills turtles stranded in 2009 and 2011 on the coast of Rocha Department, Uruguay. The epibiota was composed by algae from the class Phaeophyceae (Sphacelaria sp. and Hincksia mitchelliae) and invertebrates from the classes Cirripedia (Platylepas hexastylos, Chelonibia testudinaria and Amphibalanus improvisus) and Hirudinea (Ozobranchus margoi), with greater predominance of P. hexastylos cirripeds (n= 365…
Data from: Phylogenomics of Lophotrochozoa with consideration of systematic error
2016
Phylogenomic studies have improved understanding of deep metazoan phylogeny and show promise for resolving incongruences among analyses based on limited numbers of loci. One region of the animal tree that has been especially difficult to resolve, even with phylogenomic approaches, is relationships within Lophotrochozoa (the animal clade that includes molluscs, annelids, and flatworms among others). Lack of resolution in phylogenomic analyses could be due to insufficient phylogenetic signal, limitations in taxon and/or gene sampling, or systematic error. Here, we investigated why lophotrochozoan phylogeny has been such a difficult question to answer by identifying and reducing sources of sys…
