| digesta kinetics in gazelles in comparison to other ruminants: evidence for taxon-specific rumen fluid throughput to adjust digesta washing to the natural diet. | digesta flow plays an important role in ruminant digestive physiology. we measured the mean retention time (mrt) of a solute and a particle marker in the gastrointestinal tract (git) and the reticulorumen (rr) of five gazelles and one dikdik species. species-specific differences were independent from body mass (bm) or food intake. comparative evaluations (including up to 31 other ruminant species) indicate that mrt git relate positively to bm, and are less related to feeding type (the percentage ... | 2015 | 25637787 |
| the postnatal ontogeny of the sexually dimorphic vocal apparatus in goitred gazelles (gazella subgutturosa). | this study quantitatively documents the progressive development of sexual dimorphism of the vocal organs along the ontogeny of the goitred gazelle (gazella subgutturosa). the major, male-specific secondary sexual features, of vocal anatomy in goitred gazelle are an enlarged larynx and a marked laryngeal descent. these features appear to have evolved by sexual selection and may serve as a model for similar events in male humans. sexual dimorphism of larynx size and larynx position in adult goitre ... | 2016 | 26997608 |
| does social status of males change their aggressive behavior repertoire in goitered gazelle (gazella subgutturosa guld., 1780)? | aggression in ungulates is a very common behavior which serves a great variety of social functions, the most important of which is territorial protection from intruders. typically during the rut, territorial males in antilopinae species have access to mating females, and territoriality leads to a drastic change in the males' lifestyle as they spend most of their aggressive efforts on protecting their territories from other males. in contrast, non-territorial males generally behave in a constant ... | 2014 | 25242724 |
| the energy-maintenance strategy of goitered gazelles gazella subgutturosa during rut. | in many polygynous ruminant species, males decrease their food intake considerably during the rut. to explain this phenomenon of rut-reduced hypophagia, two main hypotheses, the foraging-constraint hypothesis and energy-saving hypothesis, have been proposed. in our research, we assessed the behavioral strategy of goitered gazelles (gazella subgutturosa) through the rutting period. according to our findings, male goitered gazelles spent less time feeding during the rut compared to pre- and post-r ... | 2014 | 24220795 |
| behavioral responses of goitered gazelle (gazella subgutturosa) to parasitic activity of botflies. | we studied behavioral responses of goitered gazelles (gazella subgutturosa) to hypodermic botfly (family hypodermatidae) activity in the naturally arid conditions of kazakhstan. we found that the reactions of goitered gazelles are very similar to the insect-repelling behaviors of other ruminants and that most behavioral responses of goitered gazelles, such as frantic running, tail movements, and grooming, are not specific to botflies. the seasonal and diurnal changes in the intensity of the beha ... | 2014 | 24171698 |
| isolation and characterization of a cervidpoxvirus from a goitered gazelle (gazella subgutturosa) from a zoologic park in minnesota. | deerpox virus (dpv) is the sole member of the newly ratified cervidpoxvirus genus in the subfamily chordopoxvirinae. presented here is the first diagnostic report of isolation of dpv from a goitered gazelle (gazella subgutturosa). a tissue homogenate was submitted by a zoologic park to the minnesota veterinary diagnostic laboratory at the university of minnesota for poxvirus diagnostic investigation and then referred to plum island foreign animal disease diagnostic laboratory for confirmation. p ... | 2013 | 24063086 |
| the ontogeny of acoustic individuality in the nasal calls of captive goitred gazelles, gazella subgutturosa. | individualistic voices are important for establishing personalized relationships among individuals. in young animals, individual vocal identity is affected by permanent changes of the acoustics due to the growth of their vocal apparatus. different acoustic variables change uncoordinatedly, so vocal individuality should be repeatedly upgraded along development. we compared classifying accuracy of individuals and sexes by nasal calls in fast-growing goitred gazelles gazella subgutturosa at two ont ... | 2012 | 22465090 |
| [genetic diversity and relatives of the goitered gazelle (gazella subgutturosa) groups from uzbekistan, turkmenistan, and azerbaijan: analysis of the d-loop of mitochondrial dna]. | polymorphism of the nucleotide sequence of a hypervariable fragment of the d-loop (985 bp) of mtdna in 76 goitered gazelles of subspecies gazella subgutturosa subgutturosa from uzbekistan, turkmenistan, and azerbaijan was studied. the genetic similarity of gazelles from turkmenistan and uzbekistan has been identified. the population of gazelles from shirvanskaya steppe reserve (azerbaijan) is unique and strictly isolated from other groups studied. a high haplotypic (h = 0.9649 +/- 0.0091) and re ... | 2016 | 22292288 |
| does size matter? comparison of body temperature and activity of free-living arabian oryx (oryx leucoryx) and the smaller arabian sand gazelle (gazella subgutturosa marica) in the saudi desert. | heterothermy, a variability in body temperature beyond the normal limits of homeothermy, is widely viewed as a key adaptation of arid-adapted ungulates. however, desert ungulates with a small body mass, i.e. a relatively large surface area-to-volume ratio and a small thermal inertia, are theoretically less likely to employ adaptive heterothermy than are larger ungulates. we measured body temperature and activity patterns, using implanted data loggers, in free-ranging arabian oryx (oryx leucoryx, ... | 2012 | 22001971 |
| developmental changes of nasal and oral calls in the goitred gazelle gazella subgutturosa, a nonhuman mammal with a sexually dimorphic and descended larynx. | in goitred gazelles (gazella subgutturosa), sexual dimorphism of larynx size and position is reminiscent of the case in humans, suggesting shared features of vocal ontogenesis in both species. this study investigates the ontogeny of nasal and oral calls in 23 (10 male and 13 female) individually identified goitred gazelles from shortly after birth up to adolescence. the fundamental frequency (f0) and formants were measured as the acoustic correlates of the developing sexual dimorphism. settings ... | 2011 | 21976026 |

| meiosis in chromosomally heteromorphic goitered gazelle, gazella subgutturosa (artiodactyla, bovidae). | chromosomal-pairing behaviour was studied in the spermatocytes of individual goitered gazelles which were heteromorphic for a 14/15 robertsonian translocation and which possessed an autosome-to-x translocation. both translocations exhibited trivalent pairing configurations in pachytene and diakinesis/metaphase i nuclei. synapsis of the sex chromosomes during pachynema was followed by end-to-end association of the x and y during diakinesis/metaphase i. the only univalents identified were of the y ... | 1994 | 8162319 |
| chromosomal polymorphism in sand gazelles (gazella subgutturosa marica). | a total of 84 gazella subgutturosa from three captive populations (two in saudi arabia, one in qatar) were karyotyped. the number of chromosomes is 33, 32, or 31 for the males and 32, 31, or 30 for the females because of the x-autosome translocation that is common in the genus and a centric fusion between the two pairs of acrocentric chromosomes. the g- and r-banded karyotypes of gazelles translocated show that this fusion is the same as that previously reported for gazelles from jordan. the pre ... | 2004 | 8270771 |
| the first serological evidence for rift valley fever infection in the camel, goitered gazelle and anatolian water buffaloes in turkey. | rift valley fever (rvf), a vector-borne zoonotic disease, is caused by a phlebovirus (family bunyaviridae). the virus was initially characterized approximately 80 years ago in kenya and disseminated to many countries in the continental africa, saudi arabia, and yemen. the infection has not been reported in turkey. in this study, blood serum samples collected from camel (camelus dromedairus), goitered gazelle (gazella subgutturosa subgutturosa), and buffaloes (bubalus bubalis linneaus) from 2000 ... | 2017 | 28861841 |
| escaping behavior in goitered gazelle. | prey species modify their behaviors in response to predation risks to minimize their vulnerability and enhance their survival. when a predation risk arises, gregarious, open-habitat-dwelling ungulates usually increase their vigilance rate and enlarge their herd sizes, which are the two antipredator responses that are most often investigated. however, other reactive responses, as well as prey risk assessments and escape strategies depending on a predator's approach behavior, are less explored. in ... | 2018 | 29274760 |
| the first report of pyrrolizidine alkaloid poisoning in a gazelle (gazella subgutturosa) - histopathologic diagnosis. | pyrrolizidine alkaloids (pas) are natural phytotoxins found in thousands of plant species around the world. they are probably the most common poisonous plants affecting livestock, wildlife and humans. the disease occurs almost entirely as a consequence of chronic poisoning and in general ends fatally. in the present study, pas poisoning was investigated in a gazelle with hepatic encephalopathy associated with severe neurologic signs. the main clinical signs included head pressing, progressive de ... | 2016 | 28652845 |
| unusually high-pitched neonate distress calls of the open-habitat mongolian gazelle (procapra gutturosa) and their anatomical and hormonal predictors. | in neonate ruminants, the acoustic structure of vocalizations may depend on sex, vocal anatomy, hormonal profiles and body mass and on environmental factors. in neonate wild-living mongolian gazelles procapra gutturosa, hand-captured during biomedical monitoring in the daurian steppes at the russian-mongolian border, we spectrographically analysed distress calls and measured body mass of 22 individuals (6 males, 16 females). for 20 (5 male, 15 female) of these individuals, serum testosterone lev ... | 2017 | 28578533 |
| development of juvenile goitered gazelle social behavior during the hiding period. | in many ungulate species, social organization of adults is based on a linear dominance hierarchy, which in turn often positively correlates with age, body mass, and horn/antler size. in contrast to the social behavior of adults and specific mother-offspring interactions, the process of ungulate socialization in juveniles through contacts with other conspecifics is poorly understood, especially for hider species during their initial hiding period. therefore, we investigated this process in goiter ... | 2017 | 28941796 |
| mother-young recognition in goitered gazelle during hiding period. | the mother-young recognition process is crucial for the growth and survival of progeny. in "follower" ungulate species, vocal and visual cues have been found to play a leading role in the mother-young identification process from the first days postpartum, with olfactory cues also important in establishing the initial selective mother-young bond immediately after birth. in "hider" species, however, much less has been documented of mother-young recognition behaviors, especially in their natural ha ... | 2017 | 28552706 |
| antipredator tactics are largely maternally controlled in goitered gazelle, a hider ungulate. | predation is usually the primary cause of infant death among ungulate species, with the annual variation in the survival of neonates over their first summer a major factor in the population dynamics of many ungulates. consequently, the maternal rearing strategy of a species is crucial for its reproductive success. since the roles mothers and fawns play in the implementation of antipredator strategies in hider species have been poorly understood until now, this paper considers this behavior in th ... | 2017 | 28088552 |
| suckling behavior in goitered gazelle: do females invest more in twins or singletons? | the mother-offspring social unit is a universal feature in the social life of all mammals and nursing is the most direct and vital component of maternal investment in young. living in diverse environments, various ungulate species have different strategies for rearing offspring, from bearing a single, relatively large newborn and supplying only limited amounts of milk, to bearing several relatively small newborns with intensive post-partum lactation. in this paper, we consider the rearing strate ... | 2015 | 26150400 |
| seasonal dynamics of agonistic displays in territorial and non-territorial males of goitered gazelle. | aggression serves a great variety of social functions, one of which is protection of individual territories from intruders. territorial males of many antelope species show aggressive noncontact displays, and only rarely fight. it has been suggested that ungulate males tend to have more frequent and longer aggressive interactions with rivals of similar age or social status than with males of dissimilar status. in the present paper, we test whether territorial and non-territorial males behave in a ... | 2015 | 25435489 |
| roaring function in male goitered gazelles. | most of the vocalizations of antilopinae males are soft and usually only heard from a very close distance. the goitered gazelle is a rare exception to this rule, and during the rutting period territorial males of this species are among the noisiest antelopes. rutting vocalization is such an essential part of the rutting behavior in goitered gazelle that adult males have a hypertrophic larynx, the muscle tissues of which increase considerably in size during the rut. we were interested in the freq ... | 2014 | 24915642 |
| object-horning in goitered gazelle: agonistic or marking behaviour? | we studied object-horning behaviour in goitered gazelles in the natural, arid environment of kazakhstan over a 6-year period. we found that object-horning was used by adult males mostly as a threat display during territorial conflicts. therefore object-horning was observed most frequently in territorial single males during the rut in november-december. object-horning, though, also had a marking effect, with the males' use of this behaviour leaving visible traces that advertized the location of p ... | 2014 | 24365541 |
| seroprevalence of five zoonotic pathogens in wild ruminants in xinjiang, northwest china. | wild ruminants are at risk for zoonotic pathogen infection as a result of interactions with domestic animals and humans. one way to assess the level of a wild ruminant disease in a population is to determine the seroprevalence of the pathogen of interest. the objective of this study was to determine the seroprevalence of five zoonotic pathogens in wild ruminants in xinjiang, northwest china. in 2009 and 2011-2015, 258 wild ruminant sera samples were collected from various species. samples were o ... | 2020 | 32936059 |
| new data on the holocene mammal fauna of the ustyurt plateau. | analysis of mammalian species composition has been performed for eight archaeological sites on the ustyurt plateau. they date to the range from the middle subboreal to the middle subatlantic. the modern species composition of large mammals formed by the end of the middle holocene (subboreal 2) and did not change until the early 20th century. the ungulate species composition and ratio on the plateau showed geographical variation and changed over time. boars were always rare or absent in the north ... | 2020 | 32632837 |
| gut microbiota plasticity influences the adaptability of wild and domestic animals in co-inhabited areas. | due to the increased economic demand for livestock, the number of livestock is increasing. because of human interference, the survival of wild animals is threatened in the face of competition, particularly in co-inhabited grazing pastures. this may lead to differences in the adaptability between wild and domestic animals, as well as nutritional deficiencies in wild animals. the gut microbiota is closely associated with host health, nutrition, and adaptability. however, the gut microbiota diversi ... | 2020 | 32117147 |
| morphological diversity and ecological niche divergence in goitered and sand gazelles. | the phylogeny and species boundaries of gazella subgutturosa and g. marica have been long debated. the achievements of past conservation efforts have been compromised by a lack of knowledge about the phylogeny and taxonomic status of different populations. we integrated the recent genetic findings by previous studies with morphometric analyses and ecological niche modeling (enm) to assess discreteness among populations of these gazelle species in asia. taxonomic diversity of gazelles was investi ... | 2020 | 33144982 |
| repeated hybridization of two closely related gazelle species (gazella bennettii and gazella subgutturosa) in central iran. | interspecific hybridization increasingly occurs in the course of anthropogenic actions, such as species translocations and introductions, and habitat modifications or occurs in sympatric species due to the shortage of conspecific mates. compared with anthropogenically caused hybridization, natural hybridization is more difficult to prove, but both play an important role in conservation. in this study, we detected hybridization of two gazelle sister species, gazella bennettii (adapted to dry area ... | 2020 | 33144971 |
| a three-dimensional pelvimetric assessment on pelvic cavity of gazelle (gazella subgutturosa) by computed tomography. | the gazelles (gazella subgutturosa), which are at the risk of extinction and are legally protected, have a cultural and aesthetic value in turkey. it becomes incredibly important to increase their numbers in order to ensure their survival. in this context, it is required to examine thoroughly the pelvic cavity which contains reproductive organs and is used as the birth canal, as well. this study was conducted to determine the pelvimetric data of the gazelles by scanning their pelvic cavity via a ... | 2020 | 32761680 |
| diversification and subspecies patterning of the goitered gazelle (gazella subgutturosa) in iran. | goitered gazelles, gazella subgutturosa, exist in arid and semiarid regions of asia from the middle to the far east. although large populations were present over a vast area until recently, a decline of the population as a result of hunting, poaching, and habitat loss led to the iucn classification of g. subgutturosa as "vulnerable." we examined genetic diversity, structure, and phylogeny of g. subgutturosa using mitochondrial cytochrome b sequences from 18 geographically distant populations in ... | 2020 | 32607197 |
| three-dimensional modelling of computed tomography images of limb bones in gazelles (gazella subgutturosa). | the objective of the present study was to model in 3d the detailed morphometric features of the thoracic and pelvic limb bones of the gazelle (gazella subgutturosa), whose natural habitat is only in the sanliurfa province, by using multidetector computerized tomography (mdct) images. materials from 14 (7 male and 7 female) dead gazelles were collected from the harran university veterinary medicine faculty clinics during or after treatment. mdct images of the gazelles were taken and saved as dico ... | 2020 | 32319123 |
| female-female aggression in goitered gazelles: the desire for isolation. | in contrast to males, which compete with other males for access to mates, females compete with each other for forage-rich sites, birthing grounds, comfortable resting places, and access to sources of water and salt licking locations. this behavior has been observed in many species. however, many agonistic interactions between females occur where resources are not immediately at stake, and the reasons for their rivalry are often unclear. therefore in this paper, i want to analyze the main causes ... | 2019 | 31091464 |
| diversity of risk assessment patterns in antipredator behavior of goitered gazelles. | in predator-prey encounters, risk assessment and threat identification are particularly important aspects in the prey's decision in how, when and where to escape. previous studies devoted to this topic investigated mostly factors influencing risk perception by a prey animal and on its decision when to flee; however, information on the diversity of risk assessment displays is still very limited. therefore in this paper, i considered various display types of risk assessments and the circumstances ... | 2019 | 30550838 |
| sequence diversity of mhc class-ii drb gene in gazelles (gazella subgutturosa) raised in sanliurfa of turkey. | in this study, we aimed to assess the sequence diversity of major histocompatibility complex (mhc) class-ii drb gene at exon 2 in gazelles raised in sanliurfa province of turkey. twenty dna samples isolated from gazelles (gazella subgutturosa) were used for sequencing exon 2 of mhc class-ii drb gene. target region was amplified by polymerase chain reaction (pcr) and their products were directly sequenced. nine of these 20 samples yielded unambiguously readable sequences. three of the nine sample ... | 2018 | 30262701 |
| vigilance, staring and escape running in antipredator behavior of goitered gazelle. | predation is a very powerful force that shapes many ungulate traits. it is widely known that increasing vigilance intensity is costly and leads to a decline of forage intake. consequently, ungulates gather into larger groups to reduce an individual vigilance burden by using the "many eyes" effect and to enhance their survival through the "safety in numbers" effect. vigilance rate and related aggregation changes are two of the most discussed antipredator responses of ungulates to predation risk, ... | 2018 | 30036640 |
| interdigital necrobacillosis associated with trueperella pyogenes in goitered gazelles ( gazella subgutturosa). | this study presents the clinical findings, treatment results, and gross pathology of trueperella pyogenes-associated interdigital necrobacillosis in captive goitered gazelles ( gazella subgutturosa). four male and two female gazelles presented with weight loss, front limb swelling, and persistent lameness despite antibiotic treatment. the animals were reluctant to bear weight on the affected limbs, and the diagnosis of interdigital necrobacillosis was made based on physical exam, bacteriologic e ... | 2018 | 29900794 |
| alarm signals in goitered gazelle with special reference to stotting, hissing and alarm urination-defecation. | compared to solitary species, social ungulates benefit from living in groups not only because of the "many eyes effect", when each individual devotes less time to vigilance and spends more time foraging and engaged in other activities, or of the "dilution effect", when the probability that any specific individual will be caught decreases with herd size, but also because of early alarm signals produced by conspecifics that provide enough time for a successful escape from predator attack. these si ... | 2018 | 29804716 |
| the use of tail-flagging and white rump-patch in alarm behavior of goitered gazelles. | tail signals and rump patch exposure in ungulates are well-documented phenomena, but there is no consensus about their functional significance, which has remained disputed. in addition, these patterns have been analyzed for only a limited number of ungulate species; and until now did not include goitered gazelles. this paper, then, will discuss these aspects of goitered gazelle antipredator behavior. i chose human harassments as predator threats and found that tail-flagging, stotting and present ... | 2018 | 29526811 |
| hematology ris for captive and wild arabian sand gazelles (gazella subgutturosa marica) of the kingdom of saudi arabia. | the arabian sand gazelle (gazella subgutturosa marica, thomas, 1897) has been extirpated throughout the arabian peninsula. captive breeding and reintroduction for conservation purposes require veterinary support and the use of hematology ris. | 2018 | 29513907 |
