Classical theories of population growth and inter-species relations are briefly reviewed. It is shown how variations in feeding habits, reproductive patterns, and other aspects of population behaviour have required modifications of the basic theory in order to make it applicable to particular species. The role of the environment in population theory is also discussed, and this opens the way to a consideration of theoretical aspects of the ecology of natural populations. The latter are admittedly too complex to encourage the application of theory in its purest and most complete form. Practical attempts along these lines have simplified the problem by dealing with ecological groups—phytoplankton, zooplankton, etc.—rather than individual species. A review is presented of the methods, aims, and results of theoretical ecological investigations of the last few years. The significance of such work with respect to higher members of the food chain is discussed, and the paper concludes with remarks on some of the unsolved problems of theoretical analysis.

Abstract Background: Tumor-associated macrophages (TAMs) have been involved in growth and metastases of human and canine mammary tumors. However, the prognostic importance of TAM specific location in canine mammary tumors (CMT) was not evaluated. In this study we evaluated the potential role of TAMs in specific histologic locations – intratumoral (iTAM) and stromal (sTAM), as well as total macrophage (tTAM) counts – as prognostic indicators in CMT. Results: Clinico-pathologic data from 66 animals with mammary carcinoma and their tumors were used in this study. Samples were stained with anti-macrophage antibody for subsequent TAM count. High levels of iTAM, sTAM, and tTAM were related with clinical stage and vascular invasion. Additionally, tTAM alone revealed a relation with tumor size, while high levels of sTAM and tTAM also were correlated with node metastasis and a poor prognosis based on survival analysis. Conclusions: CMT with aggressive features can reveal higher TAM counts. TAMs are associated with vascular invasion and nodal metastasis, and sTAM and tTAM counts are correlated with overall survival, consequently leading to the conclusion that sTAM and/or tTAM counts could be used as prognostic indicators in canine mammary invasive carcinomas.
