“…This trend is unexpected considering the rich behavioral repertoire and sensory adaptations found in reptiles. Chameleons, for example, can walk along vertical substrates upside-down, independently move their eyes, are highly successful predators, and are known for their camouflage (Ketter-Katz et al 2020). Sea turtles are famous for their remarkable navigation skills that enable them to reach their home beach years after hatching (Lohmann et al 2022).…”

For 100 years, the Journal of Comparative Physiology-A has significantly supported research in the field of neuroethology. The celebration of the journal’s centennial is a great time point to appreciate the recent progress in neuroethology and to discuss possible avenues of the field. Animal behavior is the main source of inspiration for neuroethologists. This is illustrated by the huge diversity of investigated behaviors and species. To explain behavior at a mechanistic level, neuroethologists combine neuroscientific approaches with sophisticated behavioral analysis. The rapid technological progress in neuroscience makes neuroethology a highly dynamic and exciting field of research. To summarize the recent scientific progress in neuroethology, I went through all abstracts of the last six International Congresses for Neuroethology (ICNs 2010–2022) and categorized them based on the sensory modalities, experimental model species, and research topics. This highlights the diversity of neuroethology and gives us a perspective on the field’s scientific future. At the end, I highlight three research topics that may, among others, influence the future of neuroethology. I hope that sharing my roots may inspire other scientists to follow neuroethological approaches.

“…Most exhibit lateral ridges that extend from the nostrils and over the eyes to join the "casque", a helmet-like crest on the crown, and some species display up to three pairs of horns, which can project widely from their forehead and/ or snout (Freedman 2014: 877, 878;Anderson & Higham 2014: 40, 41;Tilbury 2018: 61). The chameleons' bizarre appearance is further enhanced by their prominent conical eyes, which can move independently and swivel in different directions simultaneously (Ketter-Katz et al 2020). Although most species are green, yellow or brown, specialised skin cells (chromatophores and iridiphores) allow chameleons to change colour rapidly in response to their mood, temperature fluctuations, social situations or illness (Stuart-Fox 2014: 117-119;Teyssier et al 2015).…”

“…They are widely known and studied for their ability to change skin coloration ( Stuart-Fox and Moussalli 2008 ; Teyssier et al 2015 ; Whiting et al 2023 ). Chameleons are also frequently studied for many specialized traits adaptive to arboreal life, including zygodactylous feet and a prehensile tail ( Riedel et al 2015 ; Luger et al 2021 ), independent eye movement ( Ketter-Katz et al 2020 ; Lustig et al 2013 ), and a long projective tongue ( Moulton et al 2016 ). However, no reference genome is currently available for chameleons.…”

Most amniote genomes are diploid, moderate in size (approximately 1–6 Gbp), and contain a large proportion of repetitive sequences. The development of next-generation sequencing technology, especially the emergence of high-fidelity (HiFi) long-read data, has made it feasible to resolve high-quality genome assembly for non-model species efficiently. However, reference genomes for squamate reptiles has lagged behind other amniote lineages. Here we de novo assembled the first genome from the Chameleonidae family, the panther chameleon (Furcifer pardalis). We obtained telomere-to-telomere contigs using only HiFi data, reaching a contig N50 of 158.72 Mbp. The final chromosome-level assembly is 1.61 Gbp in size and 100% of primary contigs were placed to pseudochromosomes using Hi-C interaction data. We also found that sequencing depth > 30 folds can ensure both the integrity and accuracy of the genome, while insufficient depth led to false increase in genome size and proportion of duplicated genes. We provide a high-quality reference genome valuable for evolutionary and ecological studies in chameleons as well as providing comparative genomic resources for squamate reptiles.
