Can autistic child learn to read to Library. Margarita Gil-Fernandez. Information on scavenging by jaguars is scarce, dispersed and little documented in the scientific literature, producing a shallow understanding of this phenomenon. Therefore, the aim of this paper is to describe the behavior of multiple Therefore, the aim of this paper is to describe the behavior of multiple jaguars scavenging on single carcasses of olive ridley sea turtles Lepidochelys olivacea that died by jaguar predation.

We carried out morning walks on Naranjo and Nancite beaches. We set up camera traps to capture the full extent of the feeding behavior on fresh jaguar-predated turtles. We recorded two scavenging events. The jaguars involved in the two scavenging events dragged or tried to drag the sea turtle carcass to a new location. This behavior could suggest the presence of intraspecific kleptoparasitism.

However, further investigation of this type is required to determine the existence of kleptoparasitism, and also to get a deeper understanding of scavenging in jaguars and its relation to prey availability. Hemos llevado a cabo caminatas diurnas en las playas Naranjo y Nancite. Se registraron dos eventos de carroñeo. A more complete perspective of carrion use by terrestrial vertebrates and about the role of predators in net carrion supply will improve our understanding of critical ecological processes, particularly those associated with energy flow A more complete perspective of carrion use by terrestrial vertebrates and about the role of predators in net carrion supply will improve our understanding of critical ecological processes, particularly those associated with energy flow and trophic interactions.

Therefore, the aims of this work were: 1 to record the scavenger species which are benefited indirectly by the predator-prey relationship between jaguars and sea turtles, and 2 to evaluate the influence of activity of vultures on the feeding behavior of the jaguar on sea turtles. During the study period a examples of predator prey relationships in the tropical rainforest of 24 predation events on sea turtles by jaguars were recorded at Nancite beach, Costa Rica. We recorded a total of 11 vertebrate species scavenging on sea turtle carcasses.

In this paper, we found that the number of days that the jaguars fed on a sea turtle carcass was correlated with the number of days that the vultures took to find the sea turtle carcass. Our work concluded that the ecological value of jaguars as a top predator, flag, umbrella and keystone species includes their role as a provider of carcasses to scavengers. Distribution and hotspots of the feeding areas of jaguars on sea turtles at a national park in Costa Rica. The conservation of remnant populations of white-lipped peccaries in Central America depends on adequate documentation of their habitat needs and behavior.

In the sea, the most common predators of adult sea turtles are sharks examples of predator prey relationships in the tropical rainforest. The diet of the white-lipped peccari Tayassu pecari was studied from July to April in Corcovado National Park, Costa Rica, through fecal analysis and direct observations.

We predicted We predicted that time budget would be diagnostic of Survival of protected white-lipped peccaries in Costa Rica. Examples of predator prey relationships in the tropical rainforest conservation of remnant populations of white-lipped peccaries Tayassu pecari in Central America depends on understanding their demography, but few quantitative data exist.

We report survival and cause-specific mortality of 25 female Annual survival was lower for female 0. Both sexes were poached and died in accidents but only females were killed by predators or died of unknown causes but not poaching. In comparison with the demography of collared peccaries Tayassu tajacuthe population of white-lipped peccaries in Corcovado National Park may be maintaining itself.

Still, protected areas may need to be expanded and or more forcefully monitored to sustain white-lipped peccaries throughout their range if additiona Interbirth interval of a free-ranging jaguar. These proportions are similar to those reported for white-lipped peccaries diet in South America, but the species consumed were different.

In Corcovado, the white-lipped peccary fed on parts of 57 plant species 37 of them fruits. Moraceae was the most represented family. In contrast, the diet of the Peruvian Amazon peccary primarily consists of plant parts Arecaceae. Costa Rican peccary diet consisted of vegetative parts from Araceae and Heliconaceae. Samples taken from rooting sites suggest that peccaries fed on earthworms.

Diet differed between months, seasons and habitats. They ate more fruits in coastal and prima Sex ratio and breeding of white-lipped peccaries Tayassu pecari Artiodactyla: Tayassuidae in a Costa Rican rain forest. White-lipped peccaries are examples of predator prey relationships in the tropical rainforest breeders in South America, but little is known about their reproduction in Central America.

There are few studies about the sex ratio of this species in the field. We studied the reproduction and We studied the reproduction and sex ratio of white-lipped peccaries during hours of field observation of four radiomarked and two unmarked herds, from July to Aprilin Corcovado National Park, Costa Rica. Sex ratio data of three additional, radiomarked herds observed in were also included. We recorded numbers of mountings, presence of newborns and numbers of nursing interactions.

The peccaries showed a distinct reproductive seasonality, with one mating peak in February and another in July. The greatest number of newborns and the peak in nursing activity were observed during July and August, when fruit availability for the peccaries was high. The adult sex ratio was significantly female biased 1. White-lipped peccary Tayassu pecari, Artiodactyla: Tayassuidae diet and fruit availability in a Costa Rican rain forest. We studied fruit availability, diet and habitat use by white-lipped peccary Tayassu pecari in Corcovado National Park, southwest Costa Rica, from July to April The results show that the availability of important fruits for The results show that the availability of important fruits for the white-lipped peccary differs between habitats and climatic seasons.

Fruit availability was highest in the primary forest than secondary and coastal forest. There was a period of shortage of fruits to ends of the wet season, during which the consumption of not seasonal resources like leaves and shafts increased. The important fruits during this what are the different types of legal reasoning of shortage were Ficus sp and Licania operculipetala.
