once again, you have posted heaps of random data and made it impossible to convey your actual point.

what does lynx feeding on deer have to do with anything.

This is very simple really.

lynx feeding on deer rips open the belly and eat.Right?So "essential wounds in bellies" not always mean that the deer was killed by " wounding in belly"
The killing technique of Eurasian lynx
"In all the cases lynx killed their
prey with a bite in the neck region. In eight (62%)
instances, the bite was from the ventral side of the neck
only, in three (23%) cases only from the dorsal side, and
in two (15%) cases bite marks could be distinguished on
both sides of the neck."
In another case post-mortem examination found thad ""one more pregnant female wolf was killed by either lynx or wolf (more likely to say that lynx"
Where does this doubt come from?

BTW
"but sometimes a normal wolf (the single case i learnt)."
This is the same case?
lynx fight with wolf,wolf serious injury?

I think the researchers in Belarus can distinguish the difference between a clawing wound that was dealt whilst the fight was occurring, and an opening in the already dead body made by a feeding lynx. Lynx do not open up carcasses using their claws, and anyway the pregnant wolves weren't even eaten so this is clutching at straws and a silly argument.

regarding the lynx and wolf fight, you already know what Mr Sidorovich thinks happened, if you disagree that is up to you. But don't deny the actual evidence presented:
Quote:
 

In all the female wolves the neck was bitten a lot and the belly of the females was open for 5-15cm. It seems to be the lynxes applied both bite and claw scratching methods.

"I think the researchers in Belarus can distinguish the difference between a clawing wound that was dealt whilst the fight was occurring, and an opening in the already dead body made by a feeding lynx."

"Lynx do not open up carcasses using their claws,"
Why? So lynx can kill the dog wounding in belly,but "do not open up carcasses using their claws"?
Open up carcasses using their claw Hmm it seems to be even easier then kill animal wounding in belly.But OK.maybe you are right here.
Anyway:
How do you know, that " the pregnant wolves weren't even eaten"? I don't have any information that "the pregnant wolves weren't even eaten"

"In contrast, we found several wolf pups of various age and pregnant wolves killed by lynx:

8 wolf pups of 2-11 months old and 2 heavily pregnant female wolves that were killed by lynxes (1997-2015, Naliboki Forest and Paazierre Forest);
one more pregnant female wolf was killed by either lynx or wolf (more likely to say that lynx, Naliboki Forest, May 2017);
at least, two wolf litters up two one month old were killed by lynxes (Naliboki Forest, April-May, 2016 and 2017),
two more litters – very plausible;
one wolf litter of 2-3 months old and their small mother were very plausibly killed by lynx (Naliboki Forest, June-July 2016);
adult male wolf plausibly died being wounded after a fight with a male lynx (Naliboki Forest, April 2017).


"regarding the lynx and wolf fight, you already know what Mr Sidorovich thinks happened, if you disagree that is up to you. But don't deny the actual evidence presented"
The problem is that some of "the actual evidence presented" are pretty debatable.
At least in one cases *Looks like wolf escaped ? without any serious injury.
So I dont see any actual evidence that the "adult male wolf plausibly died being wounded after a fight with a male lynx".


Also
I dont see any actual evidence that the "adult male wolf" most likely died from his injuries
BTW
I dont see any actual evidence that the "adult male wolf" is not small.
Do you have any problem with that?
*lynx fight with wolf,wolf serious injury?
http://v.youku.com/v_show/id_XMzI3MDcwNjg0OA==.html?spm=a2h3j.8428770.3416059.1&qq-pf-to=pcqq.group
Looks like wolf escaped without any serious injury.


"In all the female wolves the neck was bitten a lot "Look like cause of death

"and the belly of the females was open for 5-15cm. "
Once again
Maybe "pregnant female wolves had essential wounds in bellies" because stomach erea is the most vulnerable part of her body .Maybe "lynx intentionally aimed for some other vulnera-ble points."It seems to make sense,however I have a couple of doubts .
Maybe she was already dead when "the belly was open for 5-15cm"
At least we dont know for sure.Anyway this is unusual killing technique of Eurasian lynx.Thats why I have some doubts.

cats often rake the underbellies with their hind claws when they fight, this is common knowledge. And it is also common knowledge that a lynx, or any cat for that matter, will not open up a dead carcass by clawing its stomach open. 'having doubts' the evidence is right infront of you, what more do you want? like taipan said, ignore it if you want, but don't deny it.

and when i said don't deny the evidence presented, i was talking about the evidence of the pregnant wolves being killed not only by bites to the neck, but slashed bellies. i've said all i have to say on the matter of the wolf and lynx fight.

Probably you are right here ,but "open up a dead carcass by clawing its stomach open" It's not hard to imagine .


"when i said don't deny the evidence presented, i was talking about the evidence of the pregnant wolves being killed not only by bites to the neck, but slashed bellies"
What you mean by "evidence"?
Frankly speaking we have only one actual evidence from the blog:
5month old wolf pup killed by lynx
https://vadimsidorovich.files.wordpress.com/2017/06/mg_8535-short.jpg?w=840&h=570

BTW
here is interesting info:
Balkan Lynx Field Handbook


3.2.1. Assessing the cause of death
When analysing a dead animal, the first
question to be answered is: “Has it been
killed or was it consumed by scavengers
after its death?” Signs of presence of a
predator around a carcass do not mean
that the animal was killed!
If an animal has been eaten by a scavanger
only post-mortem, the tissue did not
bleed! Holes and scratches at the cadaver
show no signs of bleeding, this means that
they are not red. The certainty of the identification
of the cause of death depends on
the freshness of the carcass. If it is fresh,
different signs allow identifying the predator
or other causes of death, what is
however difficult or impossible when the
cadaver is old or only a few bones are left.
It is important to examine a carcass as early
as possible! Under wet and warm conditions,
carcasses decompose rapidly. In
summer, insects such as flies (maggots!)
or wasps can consume a considerable portion
of a carcass.
Certain prey species belong to the diet of
different predators. A roe deer for instance
is not only the main prey of lynx, but can
also be killed by dogs, wolves, foxes, and
exceptionally even by bears. Additionally,
scavengers like foxes, badgers, mustelids,
birds of prey or ravens can distort the typical
signs of a predator. From a fly up to a
bear, many animals can feed on a kill and
change its appearance.
The entire body needs to be searched
for signs of predation. They are sometimes
only visible after the whole hide is
removed. Important criteria for the identification
of a predator are:
- Type and distribution of (deadly)
injuries;
- Type of lesions of the skin (scratches,
perforations);
- Number, distance and distribution of
the skin perforations;
- Distribution and extension of bleedings;
- Lesion of the muscles;
- Lesion of the bones;
- Way of utilisation

Assessing the cause of death

Looks like you don't have any evidence that can dispelled my doubts.

I don't have a disagreement with you about the lynx and wolf fight, I don't know what happened to that wolf but I also won't brush off Mr Sidorovich's opinion, and take them more seriously then anyone on here. It is you that disagree with Mr Sidorovich, and you don't have any evidence that can prove your doubts right, so there is no point to that discussion.

comparing a tiger fight with this case is idiotic. completely different situation, different animals, different conditions.

and yet again, you copy and paste paragraph after paragraph of irrelevant text. It is tiresome.

is the word of a lynx and wolf specialist researcher not good enough evidence for you? or do you wish for the wolf carcasses to be flown over to you for examination?

bottom line is, if you want to doubt the word of an experienced outdoor researcher (about the pregnant wolves) based on your internet research then you are making yourself look either extremely ignorant, or in denial.

There is huge difference between opinion and evidence.Right.
The point is that you don't have any evidence that can dispelled my doubts .

Well tiger is a hiuge cat right?These two tiger are in a pretty good conditions.
Anyway .What you see here?

Yes because without evidence, a claim is merely an unsubstantiated idea or opinion.
"or do you wish for the wolf carcasses to be flown over to you for examination"
Easy, single photo is enought for me .

"bottom line is, if you want to doubt the word of an experienced outdoor researcher (about the pregnant wolves) based on your internet research then you are making yourself look either extremely ignorant, or in denial."
Yes I'm extremely ignorant but once again.There is huge difference between opinion and evidence.
"In all the female wolves the neck was bitten a lot "looks like this is a cause of death but I may be wrong. I'm ignorant .

Really .There is often blood around the neck and right side?
I see the same "injury" i.e longer fur on right side before the fight
Posted Image
Also you must notice that the wolf after the fight behave like healthy wolf.
Finally I dont see any injureds on the belly but "you see the lynx is working with the wolf belly"?

I don't think we should be surprised of not being able to see the injuries on the Wolf. Quite a few times on this forum, people have posted pics of short furred Dogs like Kangals where we couldn't see the wounds on them, but when zoomed in and when we saw them get medical aid, the wounds appeared suprisingly nasty when you first saw them. A Wolf usually got longer fur so I wouldn't be surprised that we can't see the injuries made by the small Lynx jaws and claws. If it made any.

But I understand the skeptism for this, I have my wondering on this. Tho neat info none the less.

Wait a monent
From Mr Sidorovich:
""Moreover, we got convinced that an adult lynx – especially a big male – can win a fight from any lone wolf. We photo-documented a fight between a not very big and quite old male lynx (older than 8 years) and a (not small) adult male wolf. The lynx threw the wolf on its back, attacking it’s belly. Obviously the lynx won the fight and most likely the wolf died from his injuries. Before the fight we photographed this easily recognizable wolf frequently, a few hours after the fight the clearly wounded wolf was photographed one more last time."
"I would like to precise something for you. Indeed, all plenty of roe deer I found to be killed by lynxes were bitten in their neck. Right. The same method lynxes used to kill wolf pups of 2-11 months old i have found. However, while fighting with an adult wolf, lynx seems to be unable biting in the wolf neck enough to kill it. Wolf is too strong in its forehand body part"

"a few hours after the fight the clearly wounded wolf was photographed one more last time"


This wolf is "clearly wounded" but "we should be surprised of not being able to see the injuries on the Wolf"?
Also ""The lynx threw the wolf on its back, attacking it’s belly.""On the photo you see the lynx is working with the wolf belly. You know what that means""
Looks like wolf was mortaly wounded in the belly right?because "you see the lynx is working with the wolf belly. You know what that means'and "while fighting with an adult wolf, lynx seems to be unable biting in the wolf neck enough to kill"
So we have only belly area for investigation.Right?In fact, the wolf have white fur on the belly. I'm surprised that we not being able to see the injuries on the Wolf belly .Especially when
The wolf is:
" clearly wounded " and it's visible on the photo.
" have white fur on the belly"
"was mortaly wounded in the belly"
Look at the photo:

Yes " anyone thinks " and this is called by "Critical thinking "

"Critical thinking is the objective analysis of facts to form a judgment."

"And this was the last time this male wolf was ever seen, so make what you will of that"
You are pretty sure that a wolf "most likely the wolf died from his injuries"?
Anyway without evidence, a claim is merely an unsubstantiated idea or opinion.

Ok Lynx rufus (bobcat) is smaller than Lynx canadensis.
The bobcat is like a small lynx (at roughly half the size of the Eurasian lynx,) and coyote is like a small wolf (at roughly half the size of the wolf) right?

And adult male wolf can be at least twice as large as"especially a big male lynx " right?



Your first mistake was to to establish, that female bobcats are very rarely ever predated by coyotes. Your next mistake was to equate the highly specialised Canadian Lynx, with the far more accomplished and generalised Bobcat. But your biggest mistate was to equate female Bobcats and male Bobcats. They may be as described by researchers, different species:

Male Bobcats can inhabit areas that groups of Coyotes do, whilst female Bobcats avoid such areas.

I thing yoy are missing my point.
I,m suprised that female bobcat was killed by coyote (single or group) because these two species are relatively close in weight. (coyotes tend to be sligtly larger than bobcats").Now I see that even adult male was killed by coyote.


Female Bobcats are almost half the weight of Coyotes, and as you established are rarely predated by Coyotes.

No.I'm talking about body size "Ok Lynx rufus (bobcat) is smaller than Lynx canadensis."
For example Lynx canadensis from Newfounland can be pretty comparable to Euroasian lynx .

EDITThis probably is a mistake kg=lbs 38 kg =38 lbs 18 kg =18 lbs

As far I know "highly specialist Canadian Lynx can occasionally take Dall's sheep and caribou"
"In summer and at low hare densities in the north, other
common prey species such as red squirrels, grouse, and voles are eaten frequently, and lynx predation
on ungulates (Dall’s sheep, caribou) and other carnivores (red fox, marten, mink, other lynx) has
been recorded."


Canadian Lynx also get killed by Fishers half their size - an animal Bobcats prey on. Male Bobcats can kill prey up to 8 times their own weight.

Behaviors of Bobcats Preying on White-tailed Deer in the Everglades
Ronald F. Labisky and Margaret C. Boulay

Department of Wildlife Ecology and Conservation, University of Florida, Gainesville 32611

Predatory behaviors of bobcats (Lynx rufus) that preyed on 39 radio-instrumented white-tailed deer (Odocoileus virginanus) in the Everglades during a 3-yr study, 1 April 1989–31 March 1992, are described and compared with those of other felids. Bobcats killed 33 fawns and six adults by administering one bite to the neck and throat region. The maximum prey:predator weight ratio was 8:1. Twelve (31%) of 39 kills were dragged 2–10 m to concealment cover before being eaten. Twelve (71%) of 17 carcasses that were not dragged from the kill site exhibited a characteristic death form in that the head on each was twisted backwards (throat dorsal) and positioned diagonally under the shoulder. Feeding was initiated on large muscle masses, predominantly on the hindquarters. Bobcats eviscerated 29 (83%) of 35 carcasses, severed one fore- or hind-limbs from 18 (55%) of 33 kills, and plucked hair from 13 (33%) of 39 carcasses. Bobcats partially or completely covered 17 (52%) of 33 carcasses with plant litter. Thus, bobcats preying on deer in the Everglades displayed notable differences in eviscerating, feeding, and covering behaviors.


They are thus a more superior predator than the slightly larger rabbit hunting Canadian Lynx.

"But your biggest mistate was to equate female Bobcats and male Bobcats. They may be as described by researchers, different species"

C'mon man .I'm not suprised that adult male bobcats are typically larger and have more muscular body and in consequence more "brave".You sound surprised by that.I'm surprised that you're surprised by this.

"Male Bobcats can inhabit areas that groups of Coyotes do, whilst female Bobcats avoid such areas."
Yes It would be crazy if female weren't instinctively far more risk-averse than male bobcat.Right?


I am not surprised at all, I already knew it, I just wish you had.

I dont think anybody is doubting his expertise, but this wouldn't be the 1st time at field researcher has said something that was ultimately wrong or heavily exaggerated. I think back to Beggs (?) account involving a leopardess failing to kill a honey badger (the badger's scalp was ripped off IIRC), they stated the leopardess was 'severely mauled' with 'deep wounds', yet said leopardess proceeded to kill a civet shortly after.


I remember that: they said the HB produced "deep bleeding wounds on the leopard's chest and front legs".

Very similar to this:
