ing our period of observation. 

As far as I could tell, all four trunks were equally suitable for both species. None was noticeably thicker than the others. The one with Marmoset holes seemed to have approximately as many holes as the trunk of any hole tree I have ever seen in Marmoset territory. This would suggest that the Marmosets here have taken all that they wanted. And left the left-over for the squirrel(s). (The Marmosets probably have not spread to other trunks simply because they like to have their holes close together. It must make feeding easier. SEE ALSO BELOW.) 

The two species of mammals certainly must compete with one another. For space and to escape predators. And the feeding activities of one must influence the amount of food available to the other. Possibly each reduces the food availability to the other. On the other hand, it is also conceivable that the injuries to the tree inflicted by one species could increase supplies (sap flow, and/or new bark) available. 

The competition may be controlled in any one or all of several ways. In the first place, the squirrel seems to be much rarer than the Marmoset in "hedges" here. (It probably is the same species of more extensive forest.) And there may be temporal segregation. The squirrel feeding in the middle of the day, and also during rain. The Marmoset feeding earlier and later, and only during fine weather. 

Be that as it may, the distribution of marks on 

Transcription Notes:
This page is about the analysis and predictions concerning Marmosets and their relationship with the ecosystem in which they preside. (The first "ing" is a continuation of the word "during" as the last word of the previous page.)
