Impact of Collared Peccaries Dycotiles tajacu (Artiodactyla: Tayassuidae) on understory vegetation in the tropical rainforest of the Nogal-La Selva Biological Corridor, Costa Rica

Rev. biol. trop; 72 (1), 2024
Abstract Introduction: Evidence suggests that herbivores, such as peccaries, shape vegetation structure and diversity through predation, trampling, dispersal, and rooting behavior. Objective: To evaluate the impact of peccaries (Dycotiles tajacu) on the understory vegetation of the tropical rainfores...

Bone Anatomy of the Thoracic Limb in the Common Hippopotamus (Hippopotamus amphibius) and White Rhinoceros (Ceratotherium simum)

Int. j. morphol; 41 (6), 2023
SUMMARY: Although megaherbivores do not belong to the Brazilian fauna, they can be found in national zoos, which makes it important to know the anatomy of the locomotor apparatus to contribute to the clinical routine of zoos and veterinary rehabilitation centers. Thus, the aim of this study was to descri...

Anatomical description of the skulls of peccaries (Tayassu tajacu, Linnaeus 1758) by computed tomography

The aim of this study was to evaluate the anatomical structures of the skulls of peccaries to establish the basis for their clinical study and future preclinical research. Ten skulls of adult peccaries were subjected to tomographic examination. The data obtained were processed via three-dimensional image...

B-mode and Doppler ultrasonography of abdominal structures of the peccary (Tayassu tajacu, Linnaeus 1758)

This study used B-mode and Doppler ultrasonography to characterize the abdominal structures of healthy peccaries raised in captivity. Fifteen peccaries were used for this study. The urinary vesicle appeared as an ovoid structure, located in the abdominal and pelvic transition, with a hyperechogenic, thin...

Valores ecobiométricos e índice de resistividade da artéria oftálmica externa em catetos (Tayassu tajacu, Linnaeus, 1758)

Foram avaliados ultrassonograficamente, pela via transpalpebral, 28 bulbos oculares de 14 catetos adultos, através de técnica padronizada pelo operador. Adicionalmente foi realizado o estudo hemodinâmico da artéria oftálmica externa pela técnica de Doppler colorido. Os dados coletados foram analisa...

Behavioral activities of white-lipped peccary (Tayassu pecari, Link, 1795) in a semi-intensive farming system in Brazil

This study aimed to describe the main behaviors of white-lipped peccaries (Tayassu pecari) expressed in a semi-intensive production system in Brazil. The behavioral activities of two groups of peccaries allocated in two paddocks were assessed, totaling 17 adult animals and eventual pups in different deve...

Avaliação cardiorrespiratória e de sedação da associação de dexmedetomidina-butorfanol-midazolam ou detomidina-butorfanol-midazolam em catetos (Pecari tajacu)

A presente pesquisa comparou os efeitos cardiorrespiratórios, hemogasométricos e sedativos da associação midazolam (0,41mg/kg) e butorfanol (0,31mg/kg) acrescida de detomidina (157μg/kg) (DTMB) ou dexmedetomidina (36μg/kg) (DXMB) em catetos. Catetos adultos (n=20) foram distribuídos em dois grupos...

A novel Betacoronavirus characterised in collared peccaries from the Rio de Janeiro Zoo (Brazil) killed by unknown disease

Mem. Inst. Oswaldo Cruz; 115 (), 2020
In an enclosure with nine collared peccaries (Pecari tajacu) from the Rio de Janeiro city Zoo, Brazil, one specimen was found dead and two others developed prostration, apathy and dehydration, resulting on its death. Necropsy of two animals pointed to pulmonary and renal damage. Histological examination ...

In vitro maturation of collared peccary (Pecari tajacu) oocytes after different incubation times

Pesqui. vet. bras; 38 (9), 2018
Oocyte in vitro maturation (IVM) is the first step of the in vitro reproductive technologies that enables mature oocytes to be generated ex vivo and after used for embryo production. In this sense, the establishment of culture environment, as oocyte incubation time, is essential for the success of the IV...

Assessment of the vertebral heart scale and cardiothoracic ratio to standardize the heart size of collared peccaries (Tayassu tajacu Linnaeus, 1758) restrained with ketamine and midazolam

Pesqui. vet. bras; 38 (8), 2018
Wild species, especially those threatened with extinction, are increasingly being investigated to obtain information that can be useful for their preservation. The objective of the present study was to standardize the vertebral heart scale (VHS) and cardiothoracic ratio (CTR) of the collared peccary (Tay...
