Preference tests are commonly used to assess fish behavior and cognition in several research fields. This study aimed to investigate how fish perform in a preference test involving extended habituation to the apparatus, which was expected to reduce stress. We contrasted the choice between a sector of the apparatus with natural vegetation, expected to be the preferred stimulus, and a barren sector.

- Islands serve as important evolutionary sites for creating new species but are vulnerable to environmental threats.
- The Ponza grayling, an endangered butterfly unique to two small islands in Italy, faces challenges due to its limited habitat and declining population.
- Researchers created a detailed reference genome for the Ponza grayling, paving the way for studying its genetic diversity and evolution, despite the difficulties in gathering certain genomic data.
The Australian lungfish is a primitive and endangered representative of the subclass Dipnoi. The distribution of this species is limited to south-east Queensland, with some populations considered endemic and others possibly descending from translocations in the late nineteenth century shortly after European discovery. Attempts to resolve the historical distribution of this species have met with conflicting results based on descriptive genetic studies.

- Nonadaptive hypotheses suggest that eukaryotic genome size increases when purifying selection weakens, predicting a relaxed selection signature in species with large genomes like lungfish.
- The study found that the Australian lungfish's transcriptome shows excessive transcription, likely due to poor transcriptional control.
- It also revealed a notable relaxation in coding genes of lungfish compared to other vertebrates, supporting the idea that large animal genomes evolved in a nearly neutral environment with less constraint on expansion.
We present a genome assembly of (the Loggerhead sea turtle; Chordata, Testudines, Cheloniidae), generated from genomic data from two unrelated females. The genome sequence is 2.13 gigabases in size.
