Nowhere to hide: pumas, black bears, and competition refuges
Abstract One hypothesis for how carnivores with overlapping ecology coexist in natural systems is through heterogeneous competition landscapes, in which subordinates utilize “competition refuges” to mitigate risks associated with dominant competitors. We tested for the effects of American black bear ( Ursus americanus ) kleptoparasitism on puma ( Puma concolor ) foraging in 2 systems in North America. We also tested whether partial prey consumption exhibited by pumas in the presence of bears was better explained by rules of optimal foraging or by kleptoparasitism by black bears, and whether pumas utilized spatial competition refuges to mitigate competition with bears over carcass remains. Puma kill rates in ungulates/wk were equivalent across study systems, but 48% greater in the bear season than the no-bear season. Our analyses of handling time did not support the notion that partial prey consumption exhibited by pumas followed patterns of optimal foraging. Rather, puma handling time and prey consumption were better explained by the presence of bears. Surprisingly, pumas did not utilize spatial competition refuges to mitigate competition with black bears, and instead our results suggested they increase their kill rates to compensate for losses. Our results linking high seasonal kill rates of a top predator with kleptoparasitism by a dominant competitor provide strong evidence that the effects of predation can only be understood within a community framework. In particular, we propose that future predation studies should differentiate between relative contributions of predators and competitors on prey dynamics. Further, our results suggest kleptoparasites may indirectly impact prey populations through their effects on top predators.

Seyms_ Brugger: " Brutality
A crazy morning and a quick back of the camera shot. Zimanga's dominant Male Lion takes down a Hyeana. Not pretty. Harsh. But real. Its life in the African Bush. Nature takes no prisoners, and the Lion is King."
Seyms_Brugger: " The End Game
Vicious, brutal, unforgiving - as hard as it is to watch that is nature. The African Bush takes no prisoners. And when you are the apex predator, you are in charge. Here the dominant Male Lion of the Zimanga Pride in no uncertain way dispatches competition - in this case, an unlucky Hyaena. " Seyms_Brugger: " *Warning not for sensitive viewers 《 The Wrestle 》 When I started wildlife photography, I made a promise to myself that I would always accept what I would witness or photograph. Nature does not abide by human rules. Nature has its own delicate balance, and we simply have to accept how that balance is played out. Predators control the environment and ensure that prey numbers don't blow out of control. But predators also control each other. There is an apex predator in the African Bush and that is the Lion. Beautiful, sleek, powerful l, they have long captured the imagination of wildlife lovers the world over. And they hate Hyenas. Hyenas hate Lions. Its an eternal battle that plays out across any game reserve where these two species live together. Sometimes its just a chase. Sometimes its juts not the Hyaenas day. I appreciate that this is hard for some to see. Its violent. It's graphic. But at the end of the day is just another day in this cycle of nature. And that's what you must appreciate it for. " 
Cheetah was lucky enough to live in a very close encounter with Male leopard.

Nice one and also show good how "slow" other big cats are, when cheetah doesn´t freeze. No chance whatsoever when cheetah has even a split second to accelerate. Leopard seemed to understand it also immediately :) 
A big male leopard bumps into a lioness...
Interesting to see the leopard walking toward the lioness after having been stolen its prey... Ad, it's a impression but the male lion coming at the end of the video seems to be very impressive ! |
