Male mammals often kill conspecific offspring. The benefits of such infanticide to males, and
its costs to females, probably vary across mammalian social and mating systems. We used …

We used extensive camera-trap surveys to study interindividual interactions among
individually recognizable jaguars (Panthern onca) and plain-colored pumas (Puma …

In most mammalian species, females regularly interact with kin, which is expected to reduce
aggressive competitive behaviour among females. It may thus be difficult to understand why …

We conducted the first long-term and large-scale study of demographic characteristics and
reproductive behavior in a wild jaguar (Panthera onca) population. Data were collected …

Cryptorchidism is a genital alteration wherein one or both testicles fail to descend into the
scrotum and has multifactorial causes. A free-range adult male was captured twice in the …

To understand the ecology of the jaguar in Brazil, we compared its diet, home range,
abundance, activity patterns and habitat use among biomes, using the existing literature …

Most large reserves in Brazil do not hold viable populations of jaguars to guarantee the
species' long-term survival. Corridors linking populations have been identified as a potential …

The global population of jaguars Panthera onca has decreased significantly since the
beginning of the 20th century. Given the scarcity of demographic and biological information …

Infanticide is an antagonistic behavior that may provide an evolutionary benefit for the
perpetrator. Cases of infanticide have rarely been reported in Neotropical carnivores. The …

Jaguars (Panthera onca) are the largest predator in lowland forests of Amazonia but there
have been few studies on their occurrence and activity in such forests. Here, we used …
