🦈 Accidental catch of a juvenile Great White #shark prompts a review spanning 1862-2023. The review showed that their presence is infrequent but persistent. Evidence suggests they may be following bluefin #tuna migrations into the region. Read the full article here: doi.org/10.3897/aiep...

Did you know that #reptiles can be prey to #salmonids? In a recent study from Germany’s Ammer River, a single rainbow trout (𝘖𝘯𝘤𝘰𝘳𝘩𝘺𝘯𝘤𝘩𝘶𝘴 𝘮𝘺𝘬𝘪𝘴𝘴) was found to have consumed three juvenile grass #snakes (𝘕𝘢𝘵𝘳𝘪𝘹 𝘯𝘢𝘵𝘳𝘪𝘹) ⤵️ doi.org/10.3897/aiep... #freshwater #ecology #trophicinteractions

New study shows that the fall spawning #herring 𝘊𝘭𝘶𝘱𝘦𝘢 𝘩𝘢𝘳𝘦𝘯𝘨𝘶𝘴, an ecotype thought to be functionally extinct from the Baltic Proper, are likely still present in #coastal #waters, with #larvae observed in the southern Stockholm Archipelago during the spring of 2023 and 2024: doi.org/10.3897/aiep...

What can mitochondrial DNA reveal about #fish #evolution? 🧬 Researchers sequenced the mitochondrial #DNA of the Scaly osman 𝘋𝘪𝘱𝘵𝘺𝘤𝘩𝘶𝘴 𝘮𝘢𝘤𝘶𝘭𝘢𝘵𝘶𝘴 and compared it across 56 carp (𝘊𝘺𝘱𝘳𝘪𝘯𝘪𝘥𝘢𝘦) species. 🔎See what they found: doi.org/10.3897/aiep...
