The intensity of offshore wind farm operational noise was significantly lower compared to pile driving noise. By employing a sound propagation model and referring to established noise exposure metrics, we estimated an impact zone of 12.8 m for fishes imposed by the pile driving noise. For the Indo-Pacific humpback dolphins, the permanent (PTS) and temporary threshold shift (TTS) zones were predicted to be 32.4 m and 580.9 m, respectively.

To help rare elkhorn corals survive in Florida waters, coral researchers should place them in shallow ocean locations with fast currents, scientists at the University of Miami NOAA Cooperative Institute for Marine and Atmospheric Studies and the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science explained in a recent publication.

New research by the University of Plymouth has found more than 200 measures to protect sharks and rays across the 22 coastal states of the Mediterranean region. However, while elasmobranchs have made it onto many policy agendas, the study found considerable differences in how effectively any legislation was being monitored with no single source for tracking progress in the conservation and management of sharks at national levels.

By performing single-cell transcriptome sequencing of the zebrafish olfactory epithelium, we revealed the heterogeneity of zebrafish olfactory epithelial cell types and the molecular organization of key components in signal transduction of different olfactory sensory neuron subtypes, and characterized the cell population changes and transcriptional changes associated with exposure to alarm substances.

Osaka Metropolitan University researchers have uncovered a daily mating capacity for medaka, providing important insights into the relationship between the cost of gamete production and sexual selection.
