The cryopreservation of jaguar semen must be improved to produce high-quality biobanking doses. Until now, the rare studies of semen freezing in the species have only evaluated glycerol, always with a significant reduction in sperm quality in thawed semen. The purpose of this study was to assess the efficacy of three cryoprotectants, dimethylsulfox...

Little is known regarding the biology and behavior of the pacarana (Dinomys branickii) in both in situ and ex situ environments. A comprehensive morphological analysis of the male pacarana's genital organ is presented in this study, along with comparisons to other species belonging to the suborder Hystricomorpha. The study was conducted assessing t...

In less than seven years, 17 jaguars (Panthera onca) were killed by being run over on BR-262, in Mato Grosso do Sul. Protocols designed to preserve genetic material, such as fibroblasts derived from the advanced post-mortem skin of animals, are essential for the genetic retention of roadkill individuals. The purpose of this investigation was to det...

According to the IUCN (2014), 25% of all elasmobranch species are threatened with extinction. Reproductive technologies will become an increasingly important component of breeding programs for elasmobranchs, emphasizing self-sustaining aquarium populations and conservation efforts. The use of reproductive technologies in many terrestrial and aquati...

Assisted reproduction is necessary for conservation programs for endangered species, facilitating transport and exchange of genetic material. In this context, access to material from free-living animals is essential to increase the genetic bank of the species in question. However, adapting the possible methods to the reality of the fieldwork makes...

The Pantanal cat (Leopardus braccatus), previously known as Leopardus colocolo braccatus, is a small feline native to savanna-like areas in South America. The species' extinction risk remains unknown due to limited studies. With the propose of a breeding soundness examination, two adult males (M1–3.3 kg and M2–4.0 kg) were given medetomidine (0.1 m...

Access to data on reproduction of elasmobranchs, a group of cartilaginous fishes including modern sharks and rays, is crucial for the conservation of various species, particularly those threatened with extinction, such as the vulnerable nurse shark (Ginglymostoma cirratum, Bonnaterre, 1788), a flagship species for conservation of elasmobranchs arou...

1. One-third of elasmobranch species are threatened with extinction, and the precise assessment of their sperm parameters and quality is one stage in the development of reproductive technology for animal conservation. 2. Computer-Assisted Sperm Analysis (CASA) is the gold standard for sperm analysis; however, there were not one setup established fo...

The escalation of human-wildlife conflicts, as dirt road paving, has led to a significant increase in animal roadkill incidents, severely impacting endangered species such as the jaguar. In this context, genetic recovery of roadkill specimens emerges as a crucial strategy for preserving the genetic diversity of these species, aligning with the One...

Telmatobius culeus é um anuro alto-andino classificado como criticamente ameaçado (IUCN). Estudos sobre a sua biologia e a manejo de plantéis ex-situ são importantes ferramentas para sua conservação. Em 2010, o Parque Zoológico Huachipa iniciou um projeto de conservação ex-situ a partir de um casal proveniente de apreensões.Desde então, o Zoológico...

A combinação Cetamina-Dexmedetomidina-Midazolam foi usada 13 vezes em Dinomys branickii no PZH, revertido com Atipamezol em procedimentos pouco invasivos em animais condicionados e não condicionados para avaliação médica. Temperatura retal, frequência cardíaca, frequência respiratória e saturação de oxigênio foram analizados. O tempo de indução fo...
