Mitochondrial genome sequencing of marine leukemias reveals cancer contagion between clam species in the Seas of Southern EuropeDaniel Garcia-Souto, Seila Diaz-Costas, Alicia L Bruzos, Sara Rocha, Camila F Roman-Lewis, Juana Alonso, Rosana Rodriguez, Rodríguez-Castro Jorge, Antonio Villanueva, Luis Silva, Jose Maria Valencia, Giovanni Annona, Andrea Tarallo, Fernando Ricardo, Ana Bratos-Cetinic, David Posada, Juan Jose Pasantes & Jose MC Tubio
Clonally transmissible cancers are tumour lineages that are transmitted between individuals via the transfer of living cancer cells. In marine bivalves, leukemia-like transmissible cancers, called hemic neoplasias, have demonstrated the ability to infect individuals from different species. We performed whole-genome sequencing in eight V. verrucosa clams that were diagnosed with hemic neoplasia, from two sampling points located more than 1,000 nautical miles away in the Atlantic Ocean and the Mediterranean Sea Coasts of Spain. Mitochondrial...
Following Darwin’s footsteps: Evaluating the impact of an activity designed for elementary school students to link historically important evolution key concepts on their understanding of natural selectionXana Sá-Pinto, Alexandre Pinto, Joana Ribeiro, Inês Sarmento, Patrícia Pessoa, Leonor L. Rodrigues, Lucía Vázquez-Ben, Evangelia Mavrikaki & Joaquim Bernardino Lopes
While several researchers have suggested that evolution should be explored from the initial years of schooling, little information is available on effective resources to enhance elementary school students’ level of understanding of evolution by natural selection (LUENS). For the present study, we designed, implemented and evaluated an educational activity planned for fourth graders to explore concepts and conceptual fields that were historically important for the discovery of natural selection. Observation field notes and students’ productions...
Data From: Fit and fatty freshwater fish: Contrasting polyunsaturated fatty acid phenotypes between hybridizing stickleback lineagesCameron Hudson, Nemiah Ladd, Miguel Leal, Carsten Schubert, Ole Seehausen & Blake Matthews
Long-chain polyunsaturated fatty acids are biologically important lipids that are unevenly distributed between and throughout environments. This heterogeneity can affect the evolution of metabolic processes, as populations adapt to the resource landscape that they encounter. Here, we compare fatty acid phenotypes of stickleback over two time scales of evolutionary divergence: between two lineages with different metabolic capacities for fatty acid synthesis (i.e. different copy number of the fatty acid desaturase gene; FADS2) that independently colonized...
Stakeholders engagement as an important step for the long-term monitoring of wild ungulate populationsJoão Carvalho, Pedro Leite, Ana Valente, Carlos Fonseca & Rita Tinoco Torres
Monitoring trends in animal populations is essential for the development of appropriate wildlife management strategies. However, long-term studies are difficult to maintain mainly due to the lack of continuous funding. In this scenario, the collaboration between local stakeholders and researchers can be a fruitful partnership to monitor game species for long periods and vast territories. We present an experimental framework with the involvement of researchers, local hunters, and game managers for the continuous monitoring of...
Understanding how individual trade-offs and carry-over effects along the annual cycle influence fitness is fundamental to unravel population dynamics, but such data is particularly challenging to collect in long-distance migrants. Here, with a full annual cycle perspective of Icelandic whimbrels Numenius phaeopus islandicus, we investigate trade-offs across the entire distribution, assessing migration costs and wintering energetic balance experienced throughout the wintering range (from temperate to tropical regions), and link these to breeding parameters for two...
