For cryptic animals, especially those that resemble elements of their habitat like sticks or grasses, the limbs may also be modified to enhance the camouflage. The performance of a limb in one category may require a tradeoff, reducing performance in another category. Praying mantises provide a diverse group of insects who all use their forelegs for one function, capturing prey, while some species use them as part of their camouflage. Here we use a large database of images of mantis species to capture the variation in morphology across the order, and to calculate the largest prey that their forelegs can hold. We find that the length and thickness of the femur and the length of the tibia comprise most of the variability across species. The majority of species have similar foreleg morphology, with two large groups extending into areas of the morphospace with thicker or thinner forelegs. A geometric relationship between dimensions of the foreleg and the optimal prey diameter maps directly onto the variability across species determined by principal components analysis; legs with thinner femurs and shorter tibia can't hold large prey, and the distribution of the species across the morphospace follows the gradient of optimum prey size. These results suggest that some species trade ability to grasp larger prey for benefits including crypsis, and the praying mantises are an ideal system for studying morphological and functional variation in limbs.","PeriodicalId":501575,"journal":{"name":"bioRxiv - Zoology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140637185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Salp colonies are composed of asexually budded individuals that coordinate their swimming by multi-jet propulsion. Colonies develop into species-specific architectures with distinct zooid orientations. We hypothesize that colonial architecture drives differences in swimming performance between salps due to differences in how frontal drag scales with the number of propeller zooids in the colony. Moreover, we hypothesize that faster-swimming taxa are more energetically efficient in their locomotion since less energy would be devoted to overcoming drag forces. We (1) compare swimming speed across salp species and architectures, (2) evaluate how swimming speed scales with the number of zooids in the colony in architectures with constant and scaling frontal cross-sectional area, and (3) compare the metabolic cost of transport across different species and how it scales with swimming speed. To measure their swimming speeds, we recorded swimming salp colonies using in situ videography while SCUBA diving in the open ocean. To estimate the cost of transport, we measured the respiration rates of swimming and anesthetized salps collected in situ using jars equipped with non-invasive oxygen sensors. We found that linear colonies generally swim faster and with a lower cost of transport due to their differential advantage in frontal drag scaling with an increasing number of zooids. These findings underscore the importance of considering propeller arrangement to optimize speed and energy efficiency in bioinspired underwater vehicle design, leveraging lessons learned from the diverse natural laboratory provided by salp diversity.","PeriodicalId":501575,"journal":{"name":"bioRxiv - Zoology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140637075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While behavioral studies across different animal species have demonstrated the support of polarization vision in moving object detection within this noisy environment, little is known about how their retinal photoreceptors, absorbing polarized photons, respond to moving objects, or how each photoreceptor contributes to the collective retinal reaction to changes in polarization. In this study, we employed multi-electrode array recordings to examine the retinal neural response of squid to polarized light stimuli that were designed to simulate caustics environment. Extracellular retinal recordings not only exhibit neural activities selective to the direction of polarization but also demonstrate a significant enhancement in response to stimuli with changing polarization compared to constant polarization. This enhancement is robust in almost all recording channels, but absent in a random permutation of the recordings from different trial types. These results suggest that the retinal photoreceptors directly encode the change of polarization stimuli, thereby contributing to signal detections with polarization vision. Together, our research represents a novel neural exploration of cephalopod polarization vision in a caustic environment, and advances our understanding of how nature parses scenes with salient, dynamic polarization in animal vision.","PeriodicalId":501575,"journal":{"name":"bioRxiv - Zoology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140629026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is in part because pathogenic effects are seldom decoupled from effects of immune induction. We conducted parallel, blind virus infection experiments in the laboratory and in the field to interrogate the idea of a reproductive immunity trade-off and better understand how these ubiquitous honey bee stressors affect queen health. We found that queens injected with infectious virus had smaller ovaries and were less likely to recommence egg-laying than controls, while queens injected with UV-inactivated virus displayed an intermediate phenotype. In the field, heavily infected queens had smaller ovaries and infection was a meaningful predictor of whether supersedure cells were observed in the colony. Immune responses in queens receiving live virus were similar to queens receiving inactivated virus, and several of the same immune proteins were negatively associated with ovary mass in the field. This work solidifies the relationship between virus infection and symptoms associated with queen failure and suggests that a reproductive-immunity trade-off is partially, but not wholly responsible for these effects.","PeriodicalId":501575,"journal":{"name":"bioRxiv - Zoology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140624915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After carefully re-analyzing the data presented in Wirdateti et al. (2024), we conclude that there is little support for the authors’ statements. Importantly, the sequences of the putative tiger hair and museum Javan tiger specimens generated by the authors are not from tiger cytoplasmic mitochondrial DNA but more likely the nuclear copies of mitochondrial DNA. In addition, the high mismatches found between the two “Javan tiger” sequences generated by the authors is unusual for homologous sequences that are both from tigers and hence indicative of data unreliability. Yet, too few details regarding the quality control were provided in Wirdateti et al. (2024) to rule out the possibility of contamination introduced during the data production process. In conclusion, it is inappropriate to use these unreliable sequences presented in Wirdateti et al.
