Zoology explores the incredible diversity of animal life, from the smallest insects to the largest whales, uncovering how they behave, evolve, and interact with their environments. This field offers a window into the natural world, revealing the complex adaptations and ecological relationships that sustain our planet's biodiversity. Whether studying migration patterns or cellular mechanisms, researchers strive to understand the living systems that share our world.
On Gist.Science, we make these discoveries accessible by processing every new preprint published in this category on bioRxiv. We transform complex scientific manuscripts into both plain-language overviews for general readers and detailed technical summaries for specialists, ensuring that cutting-edge zoological research is clear and usable for everyone.
Below are the latest papers in zoology, freshly summarized and ready for you to explore.
This paper introduces OrCa-seq, a rapid, low-cost Oxford Nanopore-based protocol for parallel long-range PCR and multiplexed sequencing of rRNA and COI amplicons, which effectively enables portable, multilocus DNA barcoding and biodiversity inventories across the diverse meiofauna community.
This paper reports the first record of the ichneumonid subfamily Eucerotinae in mainland Afrotropics and describes a new species from Uganda and Cameroon, suggesting that the group's previous absence in the region was likely due to insufficient sampling rather than true distributional limits.
This study identifies a new cryptic cutlassfish species, *Trichiurus javaensis*, from the southern waters of Java, Indonesia, through an integrative taxonomic approach combining morphological analysis and mitochondrial DNA sequencing.
This study evaluates the safety, efficacy, and repeatability of a novel percutaneous reverse gingival venipuncture technique for serial blood collection across various rodent species, concluding that it is a minimally invasive, safe, and effective method that supports improved animal welfare in both clinical and research settings.
This study demonstrates that genetic selection for feed efficiency in pigs alters circadian feeding rhythms and allele frequencies in core clock genes, indicating that daily feeding patterns and their underlying genetic variability significantly influence residual feed intake.
Through an integrative taxonomic approach combining morphological and genomic analyses, researchers identified the enigmatic "Golden Orb" discovered in deep Alaskan waters as a remnant cuticle of the deep-sea anemone *Relicanthus daphneae*, highlighting the critical importance of whole-specimen collections and rigorous follow-up in resolving deep-sea biodiversity.
This study demonstrates that supplementing the diets of male rabbits with flaxseeds, particularly at an 8% concentration, significantly improves hematological parameters, enhances immunity against Rabbit Hemorrhagic Disease Virus, and optimizes lipid profiles by lowering harmful cholesterol and triglycerides while increasing HDL-C.
This study proposes a more accurate forensic method for quantifying helmeted hornbill individuals in wildlife trafficking cases by prioritizing anatomical uniqueness and DNA barcoding over traditional weight-based estimates, while establishing an 85g threshold for heavily processed specimens to improve legal outcomes.
This study demonstrates that in the *Daphnia magna*-*Ordospora colligata* system, increasing host resource availability enhances pathogen fitness but causes virulence to peak at intermediate levels, revealing that resource gradients drive non-linear disease outcomes by differentially shaping host tolerance and pathogen growth.
This study employs a hierarchical Bayesian model on an augmented global dataset to estimate species-specific malaria vector bionomic parameters, revealing significant variation in behavioral traits across *Anopheles* species and their corresponding vulnerability to insecticide-treated nets.
