The morphology and morphometric study on mandibles of lion, tiger and leopard was carried out at Sakkarbaug Zoo, Junagadh (Gujarat). The mandible is formed by two symmetrical halves fused rostrally by symphysis. The alveolar border presented six alveoli for lower incisors and two large deep alveoli for canine teeth. The average length of mandible was 19.08, 17.40 and 13.54 cm in lion, tiger and leopard, with the corresponding average mandible weight of 0.338, 0.271, and 0.145 kg, respectively. However, the width of mandible was significantly more in lion (3.28 cm) than that of tiger (2.51 cm) and leopard (1.71 cm). The mandibular height up to condyle and coronoid process in lion, tiger and leopard was 4.17 and 9.24, 4.19 and 9.16, 3.04 and 7.14 cm, respectively. Both the heights were significantly higher in lion and tiger than those of leopard. The average length of symphysis-mandibularis was significantly higher in lion (6.58 cm) and tiger (6.68 cm) than leopard (4.47 cm). The mental foramina were three in tiger and two in lion and leopard, and they were deeper in lion and tiger than the leopard. The angular process was placed at caudal border of horizontal ramus and found blunt and medially curved in all three species.

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.

Substantial Rise

Approximately 300 Asiatic lions Panthera leo persica are confined to the 1,883 km2 Gir forests in Gujarat, western India. To establish a second home for the Asiatic lion in its former range, Kuno Wildlife Division (1,280 km2, with a core 345 km2 Sanctuary) has been identified in Madhya Pradesh. To assess whether the Sanctuary has sufficient wild ungulates to support a population of lions 17 transects totaling 461 km were surveyed over an area of 280 km2 in early 2005. The density of potential ungulate prey was 13 animals km−2. There are also c. 2,500 feral cattle, left behind by translocated villagers; the cattle are considered to be buffer prey in case droughts adversely affect the populations of wild ungulates. Control of poaching, moving of two villages, grassland management and building a rubble wall around the Division to keep out livestock would lead to a substantial rise in the population of ungulates (to c. 20 animals km−2) by the end of 2007. This density would support the first group of five lions (three females and two males) due to be reintroduced in the beginning of 2008. Even if all the three females raise cubs there will be sufficient wild prey by the end of 2009 to support the males, females and cubs.

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.

AbstractThe lion (Panthera leo) is one of the most popular and iconic feline species on the planet, yet in spite of its popularity, the last century has seen massive declines for lion populations worldwide. Genomic resources for endangered species represent an important way forward for the field of conservation, enabling high-resolution studies of demography, disease, and population dynamics. Here, we present a chromosome-level assembly for the captive African lion from the Exotic Feline Rescue Center as a resource for current and subsequent genetic work of the sole social species of the Panthera clade. Our assembly is composed of 10x Genomics Chromium data, Dovetail Hi-C, and Oxford Nanopore long-read data. Synteny is highly conserved between the lion, other Panthera genomes, and the domestic cat. We find variability in the length and levels of homozygosity across the genomes of the lion sequenced here and other previous published resequence data, indicating contrasting histories of recent and ancient small population sizes and/or inbreeding. Demographic analyses reveal similar histories across all individuals except the Asiatic lion, which shows a more rapid decline in population size. This high-quality genome will greatly aid in the continuing research and conservation efforts for the lion.
