Lacistorhynchidae family 28S alignment

Mario Santoro, Bruno Bellisario, Fabio Crocetta, Barbara Degli Uberti & Marialetizia Palomba
Aim: Trypanorhyncha cestodes comprise a wide range of heteroxenous parasites infecting elasmobranchs as definitive hosts, with crustaceans, squids, and fishes acting as intermediate/paratenic hosts. Limited data exist on the larval infection of these cestodes and the role of intermediate and paratenic hosts in the life cycle of these parasites. In this study, we investigated the factors that determine the occurrence and the level of infection of Grillotia plerocerci in the skeletal muscles of various deep...

Data from: Black goby territorial males adjust their ejaculate’s characteristics in response to the presence of sneakers

Lisa Locatello, Oliviero Borgheresi, Federica Poli, Andrea Pilastro & Maria Rasotto
In many species males can rapidly adjust their ejaculate performance in response to changing levels of sperm competition, an ability that is probably mediated by seminal fluid adaptive plasticity. In the black goby, Gobius niger, female spawning in the nest of a territorial male can last hours, and males attach a viscous ejaculate to the nest roof, from which sperm are slowly released. During spawning, sneaker males attempt to approach the nest and release their...

Sp 3dpf scRNA-Seq

Maria Immacolata Arnone, Periklis Paganos, Danila Voronov, Jacob Musser & Detlev Arendt
Identifying the molecular fingerprint of organismal cell types is key for understanding their function and evolution. Here, we use single cell RNA sequencing (scRNA-seq) to survey the cell types of the sea urchin early pluteus larva, representing an important developmental transition from non-feeding to feeding larva. We identify 21 distinct cell clusters, representing cells of the digestive, skeletal, immune, and nervous systems. Further subclustering of these reveal a highly detailed portrait of cell diversity across...

Species distribution, hybridization and connectivity in the genus Chionodraco: unveiling unknown icefish diversity in Antarctica

Aim The species of the genus Chionodraco (Notothenioidei) are the most abundant icefish on the continental shelf of the Weddell Sea. While previous studies indicated that only Chionodraco hamatus and Chionodraco myersi inhabit the Weddell Sea, the third Chionodraco species, Chionodraco rastrospinosus, was recently sampled in the area. Since C. rastrospinosus is supposed to be found only at the Antarctic Peninsula and Scotia Arc, this study aimed at confirming the species classification of C. rastrospinosus...

Diapause vs. reproductive programs: transcriptional phenotypes in Calanus finmarchicus

Petra H. Lenz, Vittoria Roncalli, Matthew C. Cieslak, Ann M. Tarrant, Ann M. Castelfranco & Daniel K. Hartline
Many arthropods undergo a seasonal dormancy termed “diapause” to optimize timing of reproduction in highly seasonal environments. In the North Atlantic, the copepod Calanus finmarchicus completes one to three generations annually with some individuals maturing into adults, while others interrupt their development to enter diapause. It is unknown which, why and when individuals enter the diapause program. Transcriptomic data from copepods on known programs were analyzed using dimensionality reduction of gene expression and functional analyses...

Mitochondrial genome sequencing of marine leukemias reveals cancer contagion between clam species in the Seas of Southern Europe

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...
