One-quarter of freshwater fauna threatened with extinction.

Freshwater ecosystems are highly biodiverse and important for livelihoods and economic development, but are under substantial stress. To date, comprehensive global assessments of extinction risk have not included any speciose groups primarily living in freshwaters. Consequently, data from predominantly terrestrial tetrapods are used to guide environmental policy and conservation prioritization, whereas recent proposals for target setting in freshwaters use abiotic factors.

Australia's marine fishes DNA barcode reference library for integrated taxonomy, metabarcoding & eDNA research.

Over 15 000 species of fishes are found globally in the marine environment and DNA barcodes are used extensively to describe, catalogue, understand and manage this diversity. The dataset outlined here represents a DNA barcode reference library of the mitochondrial cytochrome c oxidase subunit 1 gene (COI) from 9767 voucher specimens (representing at least 2220 species and 288 families) of marine fishes. This publicly available dataset in the Barcode of Life Data System (BOLD) represents 17 years (2005-2022) of barcoding of marine fishes identified from Australian territorial waters.

A Randomized Controlled Feasibility Study to Evaluate the Online Delivery of Storytelling Through Music With Oncology Nurses.

Background: Oncology nurses frequently contend with intense work-related emotions stemming from their roles, which include bearing witness to suffering, managing end-of-life care, and navigating ethical dilemmas. These emotional challenges can lead to burnout, compassion fatigue, and overall psychological distress.

Objective: To determine the feasibility, acceptability, and preliminary effect of implementing Storytelling Through Music (STM) online with oncology nurses.

The macroevolutionary dynamics of pharyngognathy in fishes fail to support the key innovation hypothesis.

Key innovations, traits that provide species access to novel niches, are thought to be a major generator of biodiversity. One commonly cited example of key innovation is pharyngognathy, a set of modifications to the pharyngeal jaws found in some highly species-rich fish clades such as cichlids and wrasses. Here, using comparative phylogenomics and phylogenetic comparative methods, we investigate the genomic basis of pharyngognathy and the impact of this innovation on diversification.
