New study shows coyote inbreeding not common!

[trappincoyotes39]

I just received a new coyote study that suggest strongly that coyotes like other mammals don't inbreed much at all! Very indepth, I'll report more when I have time, so far very intresting read.

Is there a link where we can find it online?

Trappincoyotes35,
If they indeed do not inbreed which I would have guessed to be true to keep the species alive and healthy;what did the survey discuss as to distances that needed to be traveled to minimize inbreeding and is it mostly a male movement or both sexes?

Distances covered would give one an idea of the number of territories that an individual animal would enter

bryce- did you know 60% of a coyote population holds no territory?

[bblwi]

No I did not and then the next questions areeeeee

1. Is that a regional characteristic?
2. Could that also mean that there are many that are rogues due to their character or are there only a few Alpha males and females that can and do hold territory
3. Also would be interesting to know if territorial coyotes breed coyotes that are more or less likely to be terrritorial than other coyotes

Steve of you figures are right that might explain the explosive nature of coyote growth and the ebb and flow of numbers. Here in my area of WI the permissions I have still show a good amount of red sign now that mange is less common. We have some very large marshes, (swamps be better defination) wetlands that are wooded, they are really taken over by yotes and populations are extremely dense. Fox sign is minimal at best.

1) it could be a regional thing- because some of the studies were done at Logan (Utah)- although, if my memory is right- a couple of studies were quoted.

2) I am guessing that non breeding coyotes make up 99.9% of the non territorial coyotes. Most reason if not al lreasons for defending territory are denning, pup related.

3) The conclusion that I got from the study was that the non territorial coyotes come and go in several areas-

now- just to be sure I didn't mislead you- to be more accurate....60% of coyotes ...in the words of the study "did not defend territory against other coyotes"

So- on one hand, a coyote might have a territory (defined by Logan and I can accept it as the area in which he sends at least 60% of his time) but he does not defend it from intruders

Ok here is the run down, coyotes as do rodents, use fecal and urinary odor clues to discriminate between related and non related animals. To maintain genectically superior offspring.
It was noted that accumulations of feces in highly visable areas surrounding territory boundries and scent marking activity to change with the seasons. Also there is a corilation of scent marking frequency and soical rank suggests dominant animals control resources such as food and land by marking there territorys/feeding sites heavily. Also noted was many species can secrete just the anal gland secretions without the feces. Wolves, fox are two species noted as well.
They can do this by using MHC's major histocompatibilty complex which consist of glycoproteins coded unquely to every individual, but more similar to closely related animals, it was discovered that mate choosing was done by picking mates with dissimilar MHC. The MHC is an odor producing protein. The molocules are excreted through urine by way of the kidneys, and passing particles through fecal matter.
It was also noted coyotes spent more time investigating those odors from a non related member, than those from a related member. It was noted on the odor clues of fecal and urine as well that marking of the area was greater with males versus female coyotes and more so again on those odor clues from non related coyotes than related.
This shows how the coyote can distinguish related from non related, for mating, territory defense and can explain those coyotes that use nurse mates in helping to raise the pups.
More will be done I hope to see just how they process this information. Evoluntionary advancement ultimately drives behavior such as kin selection and mate selection.

did you have a link or source?

[trappincoyotes39]

Yes it is in the WRC liabrary, but I have been informed they no longer will photocopy thesis because alot of staff reduction, it was done last year 2004 by Jessica Tegt, called Coyote Recognition of Relatedness using odor cues in feces,Urine,Serum, and anal Sac Secretions, consisting of 44 pages excellent info from top to botom.

[Steve Gappa]

what library is that, exactly. Should be on their computer or published somewhere on the web.

If not, if you have time would you please make me a copy and let me know what I would owe tyou for postage, copies. I'd be interested in reading the complete study.

[trappincoyotes39]

Steve it is under the new online liabrary on the NWRC website, search coyote and you will see tons of info that is there, most is avaible for order, except thesis papers, I could send you a copy, as long as its legal for me to do so? They have a disclaimer, PM Me we will see what I can do?

[trappnman]

Very nice- thanks- didn't know that site was outthere- a sister site to Logan. Anymore in the "group"?

Heres the site:

Thanks for the links Steve.

Good information on this site. I'm sving the link for the next "Coyote control doesn't work" debate on a certain Maine fly fishing forum

When predation management programs are
implemented,pronghorn fawn sur vival and the recruit-
ment of young individuals into the adult population
can increase dramatically.Smith et al.(1986)noted
that predation management could result in 100%annual
increases in population size.In general,management
activities that remove coyotes after breeding territories
are established but prior to fawning can double fawning
success.
