| total eclipse of the zoo: animal behavior during a total solar eclipse. | the infrequency of a total solar eclipse renders the event novel to those animals that experience its effects and, consequently, may induce anomalous behavioral responses. however, historical information on the responses of animals to eclipses is scant and often conflicting. in this study, we qualitatively document the responses of 17 vertebrate taxa (including mammals, birds, and reptiles) to the 2017 total solar eclipse as it passed over riverbanks zoo and garden in columbia, south carolina. i ... | 2020 | 32244374 |
| slower rates of accumulation of dna damage in leukocytes correlate with longer lifespans across several species of birds and mammals. | although there is previous evidence showing an increase in various types of dna damage with aging in mice and humans, a comparative study determining accumulation rates of dna double strand breaks, as determined by presence of phosphorylated histone h2ax (γh2ax), in leukocytes of individuals of different ages from phylogenetically distinct species from birds to mammals was lacking. here, we demonstrate that the rate of accumulation of dna damage as measured by the dna damage marker γh2ax correla ... | 2019 | 31730540 |
| telomere shortening rate predicts species life span. | telomere shortening to a critical length can trigger aging and shorter life spans in mice and humans by a mechanism that involves induction of a persistent dna damage response at chromosome ends and loss of cellular viability. however, whether telomere length is a universal determinant of species longevity is not known. to determine whether telomere shortening can be a single parameter to predict species longevities, here we measured in parallel the telomere length of a wide variety of species ( ... | 2019 | 31285335 |
| pharmacokinetics of oral gabapentin in caribbean flamingos ( phoenicopterus ruber ruber). | gabapentin is a first-line treatment for neuropathic pain and adjunct anticonvulsant medication in humans and other species. gabapentin may have advantages over other analgesics because of its broad therapeutic range with limited adverse effects and wide availability as an oral formulation. this study determined the pharmacokinetics of gabapentin in caribbean flamingos ( phoenicopterus ruber ruber) after a single-dose oral administration of either 15 mg/kg ( n = 6) or 25 mg/kg ( n = 6). plasma g ... | 2018 | 30212356 |
| can scalar timing explain variability in scanning patterns? | why are scanning patterns so variable? theory predicts that for prey species facing non-stalking predators scans to monitor predators should occur at fixed rather than unpredictable times. yet, empirical distributions of inter-scan intervals (isis) are very variable. one hypothesis to explain variability is that animals initiate several of their scans in response to external disturbances that occur at random times. i propose, instead, that animals actually aim to initiate scans at fixed times, w ... | 2019 | 30448385 |
| pharmacokinetics of oral mavacoxib in caribbean flamingos (phoenicopterus ruber ruber). | mavacoxib is a selective cyclooxygenase-2 nonsteroidal anti-inflammatory drug that has been used for management of osteoarthritis and other inflammatory conditions in dogs. the main advantage of mavacoxib over other nonsteroidal anti-inflammatory drugs is its longer plasma half-life, leading to decreased dosing frequency. this study determined the pharmacokinetics of mavacoxib in caribbean flamingos (phoenicopterus ruber ruber) after a single-dose oral administration of 6 mg/kg (n = 6). plasma m ... | 2020 | 32212546 |
| retinal topography in two species of flamingo (phoenicopteriformes: phoenicopteridae). | in this study, we assessed eye morphology and retinal topography in two flamingo species, the caribbean flamingo (phoenicopterus ruber) and the chilean flamingo (p. chilensis). eye morphology is similar in both species and cornea size relative to eye size (c:a ratio) is intermediate between those previously reported for diurnal and nocturnal birds. using stereology and retinal whole mounts, we estimate that the total number of nissl-stained neurons in the retinal ganglion cell (rgc) layer in the ... | 2020 | 32154931 |
| first report of cestode infection in the crustacean artemia persimilis from southern chilean patagonia and its relation with the neotropical aquatic birds. | the brine shrimp genus artemia leach (crustacea, branchiopoda), a keystone group in hipersaline wetlands all over the world, offers an excellent model to study species interactions (parasitism) and to explore "hidden fauna" (avian endoparasites). the present study is the first report on the parasite infection of the south american species artemia persimilis from the southern chilean patagonia (50°s-53°s). samples were collected in los cisnes and amarga lagoons, the two most austral populations o ... | 2019 | 31403003 |
| wound myiasis in a flamingo (phoenicopterus ruber) caused by calliphora spp. larvae from northwest of iran: a case report. | myiasis is the infestation of animals or man tissues by parasitic dipterous fly larvae. wound myiasis is the result of fly egg deposition on decaying flesh or pus discharging wounds. this case report describes a type of wound myiasis caused by calliphora spp. in a flamingo (phoenicopterus ruber) from east azerbaijan province, iran. a 3-yr-old female flamingo was suffering in its left wing leading to an extensive discharging wound, which was heavily infested by maggots (fly larvae). the examinati ... | 2020 | 30697325 |
| pharmacokinetics of a sustained-release formulation of meloxicam after subcutaneous administration to american flamingos ( phoenicopterus ruber). | meloxicam is commonly used in avian medicine to relieve pain and inflammation, but the recommended dosing frequency can be multiple times per day, which can contribute to stress during convalescence. in this study, the pharmacokinetics of a sustained-release formulation of meloxicam were determined after subcutaneous administration of a single 3-mg/kg dose to eight healthy adult american flamingos ( phoenicopterus ruber). blood samples were collected before (time 0) and at 0.5, 1, 4, 8, 12, 24, ... | 2018 | 30592922 |
