Rajakaruna and Chulantha Prasanga Diyes Abstract Spinose ear tick, Otobius megnini, has a worldwide distribution causing otoaca- riasis or parasitic otitis in animals and humans. It mainly infests horses and cattle. It is a nidicolous, one-host soft tick spread from the New World to the Old World and is now distributed across all the continents. Only the larvae and nymphs are parasitic, feeding inside the ear canal of the host for a long period. Adult males and females are free-living and nonfeeding, and mating occurs off the host. Being inside the ear canal of the host allows the tick to be distributed over a vast geographic region through the distribution of the host animals. The presence of infectious agents Coxiella burnetii, the agent of Q fever, spotted fever rickettsia, Ehrlichia canis, Borrelia burgdorferi, and Babesia in O. megnini has been reported, but its role as a vector has not been confirmed. -

México. *Corresponding author: [email protected]; [email protected] Abstract: Ticks are important vectors of medical and veterinary importance pathogens in Mexico; however, the taxonomic studies of abundance, prevalence, intensity, and body distribution in white-tailed deer (Odocoileus virginianus) and bighorn sheep (Ovis canadensis) are limited. This study aimed to fill this knowledge gap in the Mexican states of Sonora, Nuevo León, and Tamaulipas. The area of study included authorized game farms where hunting is practiced. A total of 372 ticks [21 nymphs (5.65 %) and 351 adults (94.35 %); 41% female and 59 % male] were collected from 233 O. virginianus and four O. canadensis. The ticks collected from O. virginianus were identified as Otobius megnini, Rhipicephalus (Boophilus) microplus, and Dermacentor (Anocentor) nitens. Dermacentor hunteri was the only species collected from O. canadensis. Ears were the most infested region (83 females, 70 males, and 21 nymphs, 46.77 %), and the least infested body parts were the legs (10 males and nine females, 5.1 %). This study reports for the first time the abundance, intensity, and prevalence of ticks in O. virginianus in northern Mexico, particularly in the states of Tamaulipas and 177 Rev Mex Cienc Pecu 2021;12(1):177-193 Nuevo León, since the O. -

Tapirus Indicus) Considering Familiarity and Relatedness

These individual distinct vocalizations can play an important role in animal communi- cation because they can carry important information about the age, sex, personality, or social role of the signaler. Although we have good knowledge regarding the importance of individual vocalization in social living mammals, it is less clear to what extent solitary living mammals possess individual distinct vocalizations. Malayan tapirs (Tapirus indicus) are solitary living forest dwellers that inhabit tropical habitats. We recorded the vocalizations of 14 adult Malayan tapirs (six females and eight males) living in seven European zoos to answer the question of whether Malayan tapirs possess indi- vidually distinct vocalizations. Apart from sex-related differences, we found significant differences Citation: Walb, R.; von Fersen, L.; in the harmonic calls of all subjects. Surprisingly, kinship had no influence on call similarity, whereas Meijer, T.; Hammerschmidt, K. familiar animals exhibited significant higher similarity in their harmonic calls compared to unfamiliar Individual Differences in the Vocal or related subjects. -

E.C.Z.M., Joanne Dodds, V.N., Karla Berry, V.N., Abdi Arif, M.V.Sc., Polly Taylor, Vet. M. B., Ph. D., Dip. E.C.V.A.A., Andrew Routh, B. V. Sc., Cert. Zoo. Med., and Frank Gasthuys, D.V.M., Ph. D., Dip. E.C.V.A.A. Abstract: General anesthesia poses risks for larger zoo species, like cardiorespiratory depression, myopathy, and hyperthermia. In ruminants, ruminal bloat and regurgitation of rumen contents with potential aspiration pneumonia are added risks. Thus, the use of sedation to perform minor procedures is justified in zoo animals. A combination of detomidine and butorphanol has been routinely used in domestic animals. This drug combination, administered by remote intramuscular injection, can also be applied for standing sedation in a range of zoo animals, allowing a number of minor procedures. The combination was successfully administered in five species of nondomesticated equids (Przewalski horse [Equus ferus przewalskii; n ¼ 1], onager [Equus hemionus onager; n ¼ 4], kiang [Equus kiang; n ¼ 3], Grevy’s zebra [Equus grevyi; n ¼ 4], and Somali wild ass [Equus africanus somaliensis; n ¼ 7]), with a mean dose range of 0.10–0.17 mg/kg detomidine and 0.07–0.13 mg/kg butorphanol; the white (Ceratotherium simum simum; n ¼ 12) and greater one-horned rhinoceros (Rhinoceros unicornis; n ¼ 4), with a mean dose of 0.015 mg/kg of both detomidine and butorphanol; and Asiatic elephant bulls (Elephas maximus; n ¼ 2), with a mean dose of 0.018 mg/kg of both detomidine and butorphanol. -
Tapir Tracks Dear Educator
TAPIR TRACKS A Curriculum Guide for Educators 2 Tapir Tracks Dear Educator, Welcome to Tapir Tracks! This curriculum was created for classroom teachers and educators at zoos and other nonformal science learning centers to enable you and your students to discover tapirs of the Americas and Asia. Because tapirs spread seeds from the fruits they eat, these little-known mammals are essential to the health of the forests they inhabit. However, tapir populations are rapidly declining. Loss of their habitat and hunting threaten tapir survival. An international team of scientists and conservationists works to study wild tapirs, manage the zoo-based population, protect habitat, and educate local communities. We collaborate through the Tapir Specialist Group, of the International Union for Conservation of Nature (IUCN) Species Survival Commission. This packet includes background information along with lesson plans and activities that can easily be adapted for kindergarten, elementary and secondary school students (grades K-12). An online link is included for you to download images and videos to use in your teaching: http://tapirs.org/resources/educator-resources. This toolkit is designed to enable you to meet curriculum requirements in multiple subjects. Students can explore the world’s tapirs through science, environmental studies, technology, social studies, geography, the arts and creative writing activities. We hope that by discovering tapirs through these lessons and engaging activities that students will care and take action to protect tapirs -
