| active anti-predator behaviour of red titi monkeys (plecturocebus cupreus). | due to their inconspicuous behaviour and colouration, it has been assumed that titi monkeys' main anti-predator behaviour is passive crypsis and hiding. so far, active predator mobbing has been documented only for black-fronted titi monkeys, callicebusnigrifrons. here we report for the first time mobbing behaviour of red titi monkeys, plecturocebus cupreus (previously callicebus cupreus), as reaction to an ocelot (leopardus pardalis) and a boa constrictor. we also report other active anti-predat ... | 2019 | 32110716 |
| cooperative rescue of a juvenile capuchin (cebus imitator) from a boa constrictor. | the threat of predation by snakes is considered to have played a significant role in the evolution of primate sensory systems and behavior. however, we know relatively little about individual and group responses given the rarity of observed predation events. here we report an observed (filmed) predation attempt by an adult boa constrictor (~ 2 m) on a juvenile white-faced capuchin (cebus imitator) in the sector santa rosa of the área de conservación guanacaste, costa rica. the snake caught the j ... | 2020 | 33033278 |
| development of snake-directed antipredator behavior by wild white-faced capuchin monkeys: iii. the signaling properties of alarm-call tonality. | in many primates, the acoustic properties of alarm calls can provide information on the level of perceived predatory threat as well as influence the antipredator behavior of nearby conspecifics. the present study examined the harmonics-to-noise ratio (tonality of spectral structure) of alarm calls emitted by white-faced capuchin monkeys (cebus capucinus) in trees directed at photographic models of a boa constrictor, neotropical rattlesnake, scorpion eater snake, and white snake-shaped control pr ... | 2019 | 30664280 |
| leptospira interrogans in wild boa constrictor snakes from northeast brazil peri‑urban rainforest fragments. | leptospirosis, a disease that occurs worldwide, especially in tropical regions, is caused by bacteria of the genus leptospira and affects mammals, amphibians, and reptiles. boa constrictor snakes are commonly found in atlantic rainforest fragments in peri‑urban areas, which indicates a greater possibility of the contact of these animals with humans residing there. therefore, the aim of this work was to detect leptospira spp infection through molecular assays in wild b. constrictor snakes rescued ... | 2020 | 32504590 |
| identification of a novel deltavirus in boa constrictors. | hepatitis d virus (hdv) forms the genus deltavirus unassigned to any virus family. hdv is a satellite virus and needs hepatitis b virus (hbv) to make infectious particles. deltaviruses are thought to have evolved in humans, since for a long time, they had not been identified elsewhere. herein we report, prompted by the recent discovery of an hdv-like agent in birds, the identification of a deltavirus in snakes (boa constrictor) designated snake hdv (shdv). the circular 1,711-nt rna genome of shd ... | 2019 | 30940697 |
| ebola virus, but not marburg virus, replicates efficiently and without required adaptation in snake cells. | ebola virus (ebov) disease is a viral hemorrhagic fever with a high case-fatality rate in humans. this disease is caused by four members of the filoviral genus ebolavirus, including ebov. the natural hosts reservoirs of ebolaviruses remain to be identified. glycoprotein 2 of reptarenaviruses, known to infect only boa constrictors and pythons, is similar in sequence and structure to ebolaviral glycoprotein 2, suggesting that ebov may be able to infect reptilian cells. therefore, we serially passa ... | 2018 | 30524754 |
| vertebrates as a bactericidal agent. | in brazil, although a large number of animals are used in traditional medicine (at least 354 species), information about their biological activities is scarce. in this context, the objective of this study was to evaluate the bactericidal potential of zootherapeutic by-products from animals used in brazilian traditional medicine and discuss the ecological and cultural consequences of such practices. the species analyzed were: tupinambis merianae (skin), iguana iguana (skin and body fat), crotalus ... | 2018 | 29922961 |
| molecular characterization and identification of hepatozoon species miller, 1908 (apicomplexa: adeleina: hepatozoidae) in captive snakes from brazil. | species of hepatozoon are parasites frequently recorded in snakes. the species identification of this genus was based mostly on the gametocyte morphology and morphometric calculations. for more reliable results, molecular characterization, an initial step for the correct identification of hepatozoon species, has been used. this study aimed to determine the prevalence and identification of hepatozoon species in captive snakes from brazil. to that end, morphological, morphometric, and molecular da ... | 2018 | 30267181 |

| experimental modification of morphology reveals the effects of the zygosphene-zygantrum joint on the range of motion of snake vertebrae. | variation in joint shape and soft tissue can alter range of motion (rom) and create trade-offs between stability and flexibility. the shape of the distinctive zygosphene-zygantrum joint of snake vertebrae has been hypothesized to prevent axial torsion (twisting), but its function has never been tested experimentally. we used experimental manipulation of morphology to determine the role of the zygosphene-zygantrum articulation by micro-computed tomography (μct) scanning and 3d printing two mid-bo ... | 2020 | 32127376 |
| molecular detection of reptile-associated borrelia in boa constrictor (squamata: boidae) from veracruz, mexico. | the reptile-associated borrelia represent a monophyletic group of bacteria transmitted by several species of hard ticks, which has been reported to only infect amphibians and reptiles in eurasia and middle east, however, this bacterial group has not been studied in north america. the aim of this study was to assess the presence of borrelia spirochetes in blood samples of native reptiles of mexico. blood samples were directly obtained from individuals, dna extractions were performed using chelex- ... | 2020 | 32112720 |
| boaγpli: structural and functional characterization of the gamma phospholipase a2 plasma inhibitor from the non-venomous brazilian snake boa constrictor. | plasma in several organisms has components that promote resistance to envenomation by inhibiting specific proteins from snake venoms, such as phospholipases a2 (pla2s). the major hypothesis for inhibitor's presence would be the protection against self-envenomation in venomous snakes, but the occurrence of inhibitors in non-venomous snakes and other animals has opened new perspectives for this molecule. thus, this study showed for the first time the structural and functional characterization of t ... | 2020 | 32106235 |
| visual contrast and intensity affect perch choice of brown tree snakes (boiga irregularis) and boa constrictors (boa constrictor). | habitat structure can affect animal movement both by affecting the mechanical demands of locomotion and by influencing where animals choose to go. arboreal habitats facilitate studying path choice by animals because variation in branch structure has known mechanical consequences, and different branches create discrete choices. recent laboratory studies have found that arboreal snakes can use vision to select shapes and locations of destinations that mechanically facilitate bridging gaps. however ... | 2020 | 32070798 |
| genomic basis of convergent island phenotypes in boa constrictors. | convergent evolution is often documented in organisms inhabiting isolated environments with distinct ecological conditions and similar selective regimes. several central america islands harbor dwarf boa populations that are characterized by distinct differences in growth, mass, and craniofacial morphology, which are linked to the shared arboreal and feast-famine ecology of these island populations. using high-density radseq data, we inferred three dwarf island populations with independent origin ... | 2019 | 31642474 |
| antibody response in snakes with boid inclusion body disease. | boid inclusion body disease (bibd) is a potentially fatal disease reported in captive boid snakes worldwide that is caused by reptarenavirus infection. although the detection of intracytoplasmic inclusion bodies (ib) in blood cells serves as the gold standard for the ante mortem diagnosis of bibd, the mechanisms underlying ib formation and the pathogenesis of bibd are unknown. knowledge on the reptile immune system is sparse compared to the mammalian counterpart, and in particular the response t ... | 2019 | 31498825 |
