Revista de Biología Tropicalvol. DOI: Abstract: Although dietary studies are considered an important conservation tool, few studies have assessed jaguar Panthera onca diet in Costa Rica. Our results indicated that jaguar diet in this area consisted of at least 20 prey species. The green sea turtle Chelonia mydas was the most frequent item based on carcass data, while the white-lipped peccary Tayassu pecari was the major prey species according to the scat analysis.

Our results highlight the importance of combining different methods to describe the jaguar feeding habits. Further research should focus on calculating give some examples of predator-prey relationships and terrestrial prey species abundance in the study area, information that would help to complement our findings. Epub March Resumen: Aunque los estudios de dieta son una herramienta importante en la conservación de las especies, pocas investigaciones han evaluado la dieta del jaguar Panthera onca en Costa Rica.

The feeding ecology of the jaguar Panthera onca has been widely studied throughout its geographic range. The most commonly used technique of these studies has been analysis of scat samples, with other methods such as examination of carcasses used less frequently. Klare, Kambler and Macdonald also emphasized that non-invasive techniques are relatively simple and affordable compared with other methods e. For its part, Bustamante documented that the white-lipped peccary, the two-toed sloth Choloepus hoffmanni and the coati Nasua narica were the predator-preyy items found in Golfo Relationahips Forest Reserve in the Osa Peninsula.

Corrales and Cardenal and Gonzalez-Maya et al. While Montalvo reported a preference for white-tailed give some examples of predator-prey relationships Odocoileus virginianuscollared peccary and the olive ridley sea turtle Lepidochelys olivacea in Santa Rosa National Park. Likewise, few studies have used data from carcasses presumed killed by jaguars to describe its food habits. For example, researchers in Corcovado National Park Carrillo et al. The present study expands the current knowledge of jaguar slme in Tortuguero National Park, Costa Rica.

Previous research in this area has focused on the predator-prey interaction between the jaguar and the local nesting give some examples of predator-prey relationships of sea turtles What is experimental method example et al. Although these studies highlighted the importance of the green sea turtle Chelonia mydas as a food source for the local jaguar population, the role of other prey species is still unknown.

This site, known as Tortuguero beach, extends from the Tortuguero River mouth in the North to the Jalova River mouth in give some examples of predator-prey relationships South; there is also a human-made trail running parallel and along the entirety of the beach Figure 1. A Tropical Wet Forest Holdridge, borders the entire study site except rpedator-prey a coconut plantation and cattle ranch to the South, and Tortuguero village to the North end.

Data collection and analysis: Carcass data of potential prey species, believed to have been predated by a jaguar, was collected by carrying out weekly surveys along Tortuguero beach, from July to November give some examples of predator-prey relationships Additional information was also collected opportunistically while the researchers surveyed the human-made trails surrounding the study area. When a carcass was discovered, the carcass was examined for evidence of jaguar predation e.

Jaguar scats were collected, while performing the carcass data collection, along the beach and trails, from Prdeator-prey to December Upon discovery, the sample was collected in a plastic bag labeled with the date of collection and geographic coordinates. Jaguar scats were differentiated from other wild cats and carnivores based on their morphological characteristics Aranda, and associated signs e. It is important to highlight that samples were not collected when it was what is the full form of impact possible to say with certainty that they belonged to jaguars.

Each scat was soaked in a solution of water and detergent for up to 48 hours. After this period, the scat was washed with running water over fine-mesh filters and sun dried. Once dried, the non-digested prey remains e. Bones, arthropod fragments and plant material found in the samples were not identified. The frequency of occurrence FO and percent of occurrence PO were used to describe the scat contents. Camera trap records photos or videos clearly showing jaguar preying on terrestrial preys, or prey species with evident marks of a jaguar attack e.

These records were obtained as part of the long-term camera trap monitoring program conducted by Coastal Jaguar Conservation in Tortuguero What are the disadvantages of seven-segment display Park, and corresponded to 12 camera trap stations located along the human-made trail running parallel to the beach from June to December Of 1 carcasses recorded mean per year: Table 1: Jaguar Panthera onca dietary composition from carcasses and camera trap records documented in the coastal habitat of Tortuguero Examlles Park, Costa Rica.

Prdeator-prey June December Of 75 scats analyzed mean per year: The white-lipped gvie was the most frequent prey found on the scat analysis. Period: August December Our results were comparable with those obtained in other studies in Costa Rica Chinchilla, ; Carrillo et al. Although abundance of white-lipped peccary has not yet been estimated, important records of groups of more than 20 individuals have been reported roaming within the study area Coastal Jaguar Conservation, unpublished year-round.

Our study also highlights the variety of species e. The remains of a large feline in one of the scats are of great interest, since preator-prey among big cats has been rarely documented. For example, in Brazil jaguar infanticide Soares et al. Regarding pumas, Cassaigne et al. Since Tortuguero beach has a high density of jaguars yearly average of 13 individuals detected along 29 km of coastline; Coastal Jaguar Conservation, unpublished dataperhaps a jaguar attack upon a conspecific or a puma could have been triggered by give some examples of predator-prey relationships stress caused by multiple individuals converging in one spot or, a female defending her off-spring, or individuals defending their prey Azevedo et al.

A major limitation of carcass analysis was the low detectability of prey remains in closed habitats, which could lead to an under-representation of some prey species; especially smaller ones Tambling et al. Other factors that facilitated the detection were presence of black vultures Coragyps atratus around the kills and the large size of sea turtle remains sea turtle carapace length ranges from cm, which varies by species. Carcasses were not detected along the trail closed habitatas a result of the relatiomships being obscured by the vegetation, thus hindering detectionby researchers.

Since consumed parts are easily decomposed are relationships based on zodiac signs the digestive system, they are unexpected in scat samples Hayward et al. Field sample misidentification is another disadvantage of scat analysis. In Tortuguero National Park, jaguar scats were identified based on the appearance but also on other signs e. Therefore, we are prone to believe that our sampling identification in the field was prddator-prey.

Both carcass and scat analyses underestimated the importance of domestic animals as part of the jaguar diet. Although we did not find carcasses of domestic animals or their remains in scat content, we give some examples of predator-prey relationships aware of several confirmed jaguar attacks upon domestic predator-prdy Bos somr and dogs Canis familiaris in the cattle ranch Southern end of the beachthe ranger station and communities located around the study area.

Therefore, we recommend the use of other methods e. This is the first broad study of jaguar diet in Tortuguero National Park. Our results not only provide additional information regarding well-known predator-prey relationship between sea turtles and the jaguar, but also to understand the role that other prey species play in jaguar diet. Our results also highlight the importance of combining different methods to have a better representation of the jaguar feeding habits.

Further give some examples of predator-prey relationships to complement our study should focus on calculating terrestrial prey species abundance in the study area, and collecting samples from other locations e.
