Spectacled bear interaction with jaguars

[Deleted]

Now we know that the spectacled bear is the most herbivorouse of all bears if not compared to most bears.
There is very little accounts of its interaction with the jaguar though a few sources says it avoids the big cat.
This bears does not come into contact with the jaguar at a certain level (1500m) in mount andes. The account:

"Predators of spectacled bear cubs include mountain lion (Felis concolor), and possibly male bears. Spectacled bears appear to avoid jaguar (Panthera onca), suggesting that jaguar might be considered a predator. The elevational ranges of these two species in Per� and Bolivia do not overlap on the same mountain slope, but do for 900m of elevation if the entire Cordillera Oriental is considered. Here, jaguar can occur up to 1,500m in elevation and spectacled bears can descend as low as 600m in elevation (B. Peyton unpubl. data) .

I'm not sure what kind if any information I have on this topic though it is a subject of interest. Outside feedback is welcomed.

There accounts that say the tapirs main enemies are jaguars and bears. Those bears could be presumed to be spectacled bears since they are the only ones that overlaps territories or lives in the same habitat potentially as the jaguar.
The spectacled bear would usually avoid the jaguar since it feeds mainly on vegetables though it does occassionally eat meat.
There is no accounts or records of them fighting over carcasses.

To review...

"Predators of spectacled bear cubs include mountain lion (Felis concolor), and possibly male bears.

The elevational ranges of these two species in Perú and Bolivia do not overlap on the same mountain slope, but do for 900m of elevation if the entire Cordillera Oriental is considered.Here, jaguar can occur up to 1,500m in elevation and spectacled bears can descend as low as 600m in elevation (B. Peyton unpubl. data)."

I gave it the ole college try but after a strong search of the popular published literature I could not find any information on spectacled bear/jaguar relations. Apparently, what data exists on the topic is unpublished.

Figueroa, J. 2012. Andean bear Tremarctos ornatus (Carnivora: Ursidae) presence in the Amazon tropical forest of Peru. Acta Zoológica Mexicana (n. s.), 28(3): 594-606.


ABSTRACT. In Peru, the Andean bear (Tremarctos ornatus) inhabit primarily montain forest, between
1900 to 2350 m of altitude. In contrast, the records in the Amazon tropical forest (BTA), under 650 m
of elevation, are "rare". The presence of this species was evaluated in the BTA of the boundaries of the
Yanachaga Chemillén National Park with the Yanesha Communal Reserve (PNYC-RCY, 32.8 km),
during the months of February/2005 and July/2007, and the Amarakaeri Communal Reserve (RCA,
190.96 km) during the months of April-May and August/2008. In the first case, a relative abundance of
0.081 records/km during the rainy season and 0.829 records/km during the dry season. In the second, the
Andean bear was absent during the rainy season and of 0.032 records/km in the dry season. The presence in the BTA during the dry season, could be related to the consumption of palms (Arecaceae), because the
fruits that are the base of its diet in the montane and premontane forest are mature in the rainy season. In
addition, at PNYC-RCY, the BTA could be used as a corridor for the movement of the Andean bear to
other montane areas, taking advantage of the low water level on the river due to the lack of rain.

Key words: Andean bear, spectacled bear, amazon tropical forest, distribution, Peru.

Uso del bosque tropical amazónico


Peyton (1999) señaló que el oso andino no es residente permanente del BTA, siendo

encontrado raramente por debajo de los 650 msnm. En base a los resultados aquí presentados, se piensa que, si bien esta especie ciertamente no es residente permanente,
no se puede considerar rara su presencia en los BTA evaluados. En este trabajo se

propone que el oso andino visita este hábitat de forma estacional, principalmente
durante la época de estiaje.


DISCUSSION



Use of the Amazon rainforest



Peyton (1999) noted that the Andean bear is not a permanent resident of the BTA (Amazon tropical forest),
rarely being found below 650 masl. Based on the results presented here, it is thought that, although this species is certainly not a permanent resident, its presence in the BTAs evaluated can not be considered rare. In this work it is proposed that the Andean bear visits this habitat in a seasonal way, mainly
during the dry season.

"Spectacled bears appear to avoid jaguar (Panthera onca), suggesting that jaguar might be considered a predator (B. Peyton unpubl. data)".






This clearly appears not to be the case:




¿El jaguar limita la presencia del oso andino en el bosque tropical amazónico?


Anteriormente se señaló que el oso andino parecía evitar al jaguar, ya que sus rangos

altitudinales en el Perú y Bolivia no se superponían en la ladera de una misma montaña (Peyton 1999). Sin embargo, en este estudio se determinó que en las mismas áreas
donde se registró al oso andino en el PNYC-RCY y la RCA, se encontró una alta

actividad del jaguar, presentando una mayor abundancia relativa que el oso. Incluso
en el PNYC, en un árbol de Ormosia sp. (Fabaceae) se encontró marcajes de territorio
tanto del oso andino como de un felino, que muy posiblemente correspondería a un
jaguar.


Esto nos sugiere que la presencia del jaguar no influiría en el desplazamiento del

oso andino hacia y en el BTA, al menos en las zonas evaluadas y de forma directa.





Does the jaguar limit the presence of the Andean bear in the Amazon rainforest?



It was previously noted that the Andean bear seemed to avoid the jaguar, since its altitudinal ranges in Peru and Bolivia did not overlap on the slope of a single mountain (Peyton 1999). However, in this study it was determined that in the same areas
where the Andean bear was recorded in the PNYC-RCY and the RCA, a high
activity of the jaguar, presenting a greater relative abundance than the bear. Moreover
in the PNYC, in a tree of Ormosia sp. (Fabaceae) were found marks
left by an Andean bear and a big cat, the later very likely a
jaguar.



This suggests that the presence of the jaguar would not influence the displacement of the

Andean bear to and in the BTA, at least in the directly evaluated areas.

Bogotá, July 24, 2020. Thanks to a photo-trapping process carried out in the Alto Fragua Indi Wasi National Natural Park, the registration of more than 15 species of wild fauna was achieved, including cats, bears, birds and rodents.

Six camera traps located during 45 days, allowed to identify the occupation of habitats and behavior of the wild fauna present in the protected area. Likewise, it is striking that one of the cameras recorded the presence of bears and jaguars on the same path, (species that usually do not share the same transects), which indicates that, thanks to the good state of conservation of the protected area, this territory allows varieties of wild species to converge.


"It is striking that one of the cameras recorded the presence of (andean) bears and jaguars on the same path."

Camera trap study finds a threatened high-elevation mammal community in Peru

by Mike Gaworecki on 23 April 2019


"Due to their remoteness, the high-altitude tropical forests of the Cerros del Sira, an isolated mountain range in the eastern Andes of central Peru, are known to harbor a diverse array of rare and endemic species like the Sira currasow, a critically endangered bird that can be found nowhere else on Earth.

An expedition to the Cerros del Sira resulted in the first-ever camera trap footage of the Sira currasow (Pauxi koepckeae) being made available to the public in 2015. That camera trap survey also discovered the presence of Andean spectacled bears (Tremarctos ornatus) in the remote mountain range — some 100 kilometers (or 62 miles) distant from any of the bear’s previously known habitat. This was an important discovery because, while the Cerros del Sira are known to harbor a unique and diverse array of Andean and Amazonian birds, amphibians, and plants, the mammal species who call the mountain chain’s tropical forests home are still poorly known and relatively under-studied."

"Aside from revealing the distribution of and threats to the Cerros del Sira’s mammal community, the results of the camera trap survey led to a number of other insights. Pillco Huarcaya and team say that, to the best of their knowledge, their camera traps are the first to capture spectacled bears at the same location as jaguars — the two species are the largest land predators in all of South America, and they were both captured by the highest camera the team deployed, at an elevation of 1,920 meters. It was previously believed that the elevation ranges of the two species did not coincide on any single mountainside in Peru and Bolivia, only overlapping at an elevation of about 900 meters throughout the Cordillera Oriental branch of the Colombian Andes."

(a) Panthera onca and (b) Tremarctos ornatus (both captured at the same camera trap, at 1,920 m)


Camera trapping reveals a diverse and uniquehigh-elevation mammal community under threat


"Of particular significance was the first detection (to our knowledge) of the two largest land predators in South America at the same camera location, the spectacled bear and the jaguar, on the highest camera, at 1,920 m. Bears were captured at elevations as low as 1,050 m, and both species were subsequently recorded at a camera station at 1,418 m in Soqtapata Reserve (13.350862°S, 70.84539°W); Rafael Pilares, pers. comm.). It has been suggested that the elevation range of these two species in Peru and Bolivia does not overlap anywhere within a single mountain slope, and overlaps only slightly at c. 900 m throughout the Cordillera Oriental (Servheen et al., 1999)."
