Contraception is an essential tool for controlling reproduction in captive and free-ranging lions. This paper describes the treatment and contraception of 23 captive and 40 free-ranging lionesses (Panthera leo) and four captive tigers (Panthera tigris) in South Africa using 3 × 4.7 mg, 2 × 4.7 mg, 9.4 mg or 4.7 + 9.4 mg deslorelin implants. Thirty-one lionesses were treated more than once at 11- to 60-month intervals. In Brazil, two lionesses were treated with 9.4-mg implants and faecal progesterone and oestradiol concentrations were monitored for 920 days. All combinations of deslorelin showed the length of contraception to be around 30 months with one 3 × 4.7 mg treatment lasting 40 months in one captive lioness. The mean time taken to reconception was 30.1 months for the 3 × 4.7 mg combination. The faecal analyses of the lionesses in Brazil reflected quiescent ovarian activity for periods of 17 and 30 months, respectively, when small oestradiol peaks but no progesterone peaks started to appear. This confirmed the field observations in South Africa. No side effects occurred although several of the lionesses were treated repeatedly for up to 8 years. Deslorelin (Suprelorin) is a safe and effective means of controlling reproduction in captive or free-ranging populations of lions. Where contraception is to be maintained, the implementation of implants at 24-month intervals is recommended.

El presente trabajo tuvo por objetivo identificar los parásitos gastrointestinales de carnívoros silvestres del Zoológico Parque de Las Leyendas en el Perú, mediante la aplicación de cuatro métodos coproparasitológicos convencionales (directo, de Ritchie modificado, Sheather y la coloración de Ziehl Neelsen). Se trabajó con 62 ejemplares pertenecientes a 17 especies de seis familias. El 25.8% (16/62) de las muestras fueron positivas a parásitos. Panthera leo, Panthera tigris y Lycalopex sechurae fueron las especies más parasitadas (9/9, 2/3 y 3/5, respectivamente). Los parásitos identificados fueron el nematodo Toxascaris leonina (12/16), el acantocéfalo Corynosoma sp (3/16), el cestodo Atriotaenia sp (1/6) y el protozoo Giardia sp. (1/16). No se encontró asociación estadística entre las variables de edad y sexo.

AbstractWe attempted to deter crop-raiding elephants Elephas maximus by using playbacks of threatening vocalizations such as felid growls and human shouts. For this purpose, we tested two sound-playback systems in southern India: a wireless, active infrared beam-triggered system to explore the effects of night-time uncertainty in elephants' assessment of predatory threats, and a passive infrared motion detector-triggered system for closer-range playbacks. Using the first system, we deterred 90% of crop-raiding attempts using tiger Panthera tigris growls, 72.7% using leopard Panthera pardus growls, and 57.1% using human shouts, with no statistically significant difference among the three sounds. Using the second system, playbacks of tiger and lion Panthera leo growls deterred 100 and 83.3% of crop-raiding attempts, respectively, with no statistically reliable difference between the two, although video evidence indicated that elephants were more fearful of tiger growls. Our results indicate that playbacks of threatening sounds can be effective in mitigating human–elephant conflict, particularly in bolstering existing deterrent methods.

Abstract In order to promote research and conservation of species, zoos tend to promote the modernization of this system, such as the insertion of larger and adequate enclosures, environmental enrichments, and above all the conservation of species. The main objectives of this work were: to promote environmental food and cognitive enrichment for big cats, in addition to discussing the validity of this enrichment model. The study animals were 12 animals: four tigers (Panthera tigris), three puma (Puma concolor), three jaguars (Panthera onca) and two lions (Panthera leo). We used a basic ethogram for the analysis of behaviors, in which there was an analysis of specific behavior: rhythm and inactivity. With the focal animal observation method, and using the “surprise box” enrichment method, which consisted of pieces of meat inside cardboard boxes, the statistical results obtained indicated that enrichment increased social, rest and physiological behavior, and slowed down and downtime. Each species reacted in a specific way to enrichments, with better results being noticed with the Panthera onca group, followed by the Panthera leo, Panthera tigris and Puma concolor group, respectively. The theory of the use of environmental enrichment was proven and compared with other works similar to this one.
