Parasites as biological tags of divergence of black-striped pipefish, Syngnathus abaster (Actinopterygii: Syngnathiformes: Syngnathidae), populations in their natural and acquired range [PDF]
Acta Ichthyologica et Piscatoria, 2023 The presently reported study was intended to describe the current range of an Atlanto–Mediterranean fish, the black-striped pipefish, Syngnathus abaster Risso, 1827, in Ukrainian waters and to analyze biological tags (size parameters and parasites) of ...

Environmental DNA, Volume 5, Issue 6, Page 1362-1377, November 2023., 2023 This study explores the diet of one of the world's most recognizable predators, the white shark. Dietary assessments are performed by genomic analysis of cloacal swabs collected from approximately 200 live sharks. Findings from this study provide insights into the trophic ecology and feeding behavior of the white shark and key marine resources ...

DNA barcoding of reef‐associated fishes of Saint Martin's Island, Northern Bay of Bengal, Bangladesh
Ecology and Evolution, Volume 13, Issue 10, October 2023., 2023 Figures 2 and 6 consist of all the species that were sequenced and identified in this study. It also shows the phylogenetic relationship of the studied species. Abstract This study employs the DNA barcoding approach to make a molecular taxonomic catalog of reef fishes of Saint Martin's Island (SMI), an ecologically critical area (ECA), and Marine ...

Immunological tolerance in the evolution of male pregnancy
Molecular Ecology, Volume 32, Issue 4, Page 819-840, February 2023., 2023 Abstract The unique male pregnancy in pipefishes and seahorses ranges from basic attachment (pouch‐less species: Nerophinae) of maternal eggs to specialized internal gestation in pouched species (e.g. Syngnathus and Hippocampus) with many transitions in between.

The costs and benefits of larger brains in fishes
Journal of Evolutionary Biology, Volume 35, Issue 7, Page 973-985, July 2022., 2022 Traits associated with brain size across fishes. Abstract The astonishing diversity of brain sizes observed across the animal kingdom is typically explained in the context of trade‐offs: the benefits of a larger brain, such as enhanced cognitive ability, are balanced against potential costs, such as increased energetic demands.

DNA metabarcoding reveals a broad dietary range for Tasmanian devils introduced to a naive ecosystem
Ecology and Evolution, Volume 12, Issue 5, May 2022., 2022 Top‐order carnivores are essential for maintaining ecosystem stability and biodiversity. We used a metabarcoding and next‐generation sequencing approach to quantify the diet of Tasmanian devils introduced to Maria Island, Tasmania, a site outside the species’ native range.

Feeding habits of the seahorse Hippocampus patagonicus (Actinopterygii: Syngnathiformes: Syngnathidae) on the southern coast of Brazil [PDF]
Acta Ichthyologica et Piscatoria, 2018 The feeding habits of the seahorse Hippocampus patagonicus Piacentino et Luzzatto, 2004 on the southern Brazilian coast was evaluated through the gut content analysis of 82 individuals (28–110 mm in height, HT) obtained through a ...

Molecular Ecology Resources, Volume 22, Issue 4, Page 1465-1477, May 2022., 2022 Abstract Seahorses belong to the teleost family Syngnathidae that evolved a distinct body plan and unique male pregnancy compared to other teleosts. As a classic model for studying evolution of viviparity and sexual selection of teleosts, seahorse species still lack a publicly available high‐quality reference genome.

A conspicuous population of the long-snouted seahorse, Hippocampus guttulatus (Actinopterygii: Syngnathiformes: Syngnathidae), in a highly polluted Mediterranean coastal lagoon [PDF]
Acta Ichthyologica et Piscatoria, 2014 Background. Seahorses are considered vulnerable and endangered fish species in many parts of the world. We found a conspicuous and stable population of Hippocampus guttulatus Cuvier, 1829 in the Mar Piccolo of Taranto (Ionian Sea), known of its ...
