(PDF) Guanaco Predation by Pumas and Its Relationship to …
2022年8月1日 · Here, we review and synthesize data on guanaco–puma interactions, as well as other key aspects of guanaco ecology. We frame this information within food web theory to evaluate whether guanaco...
Guanaco Predation by Pumas and Its Relationship to ... - Springer
2022年8月17日 · Here, we review and synthesize data on guanaco (Lama guanicoe) and puma (Puma concolor) ecology, emphasizing trophic interactions and guanaco antipredator responses. Subsequently, we frame this information within food-web theory to assess whether guanaco predation by pumas has the potential to trigger a trophic cascade with effects on ...
What one photographer learned after spending nearly a year …
2018年11月30日 · In Torres del Paine, which is thought to contain higher concentrations of pumas than anywhere else on earth, pumas feed primarily on guanacos. Adult guanacos weigh around 200 pounds and can run...
Puma's Jaw-Dropping Face-off with a Guanaco - Animals Around …
2025年1月4日 · Witness a thrilling showdown between a puma and a guanaco on the windswept plains of Patagonia. Experience the guanaco’s spirited defense and the puma’s relentless attack, showcasing nature’s raw power and instinct. Discover how the puma outlasts and overpowers the guanaco in a stunning display of resilience and strategy.” Comparison Table
2024年12月5日 · The study examines two native species—puma (Puma concolor, a carnivore) and guanaco (Lama guanicoe, a camelid)—alongside sheep (Ovis aries), an introduced competitor of the native herbivore and an additional prey for pumas. The mathematical model developed in this work is inspired by the
assess whether guanaco predation by pumas has the potential to trigger a trophic cascade with effects on vegetation, scavengers, and nutrient dynamics. We present ideas on how to test the strength and community-level effects of guanaco–puma interactions. We end by discussing how the live shearing of guanacos and other
Francisco Joaquin Molina - Puma Predation on Guanacos in …
2020年6月23日 · I will study the interaction between pumas (Puma concolor) and guanacos (Lama guanicoe) and its impact on vegetation in the Patagonian steppe of Argentina. More specifically, I will test (1) whether food limitation alters the strength of guanacos’ behavioural responses to the risk of predation imposed by pumas, and (2) whether such changes ...
Puma predation seems to be preventing the recovery of guanaco populations at some sites, even after the removal of sheep and the relief from interspecific competition. Thus, puma predation is an additional threat to be addressed if we aim to recover guanaco populations as a key component of conservation plans for the Patagonian steppe.
Guanaco predation by pumas and its relationship to Patagonian …
Guanacos (Lama guanicoe) and pumas (Puma concolor) have coexisted in South America for at least one million years. Within Patagonian arid-land ecosystems guanaco predation by pumas can account for high levels of mortality, but the potential for this interaction to affect other trophic levels remains unknown.
Could invasive lagomorphs increase the predation risk for guanaco
2024年6月22日 · We hypothesize that invasive lagomorphs and snow dynamics indirectly drive predation risk for guanaco by puma. We employed camera-trapping data collected over multiple years and seasons in an altitudinal gradient in the Andes of Central Chile.
