From observations at several different sites in Africa, there is an "emerging consensus regarding chimpanzee social structure, territory characteristics and intergroup interactions," say two primatologists, Dr. Michael L. Wilson of the University of Minnesota and Dr. Richard W. Wrangham of Harvard, in an article in The Annual Review of Anthropology.
Female mate preferences are influenced by male territory characteristics, but not by male size or color (Hermann et al. 2015).
Alternatively, females might be able to draw the required resources from any male territory but use territory characteristics as indicators of male quality.
In the cichlid fish Tropheus moorii, an endemic of Lake Tanganyika, both intrinsic male traits and territory characteristics are plausibly used as mate choice cues by females.
Here, we test the effects of male body traits and territory characteristics on within-population female preferences and on population assortative mating in the cichlid Tropheus moorii.
In Tropheus, premating reproductive isolation between the allopatric red and bluish populations has apparently advanced to a degree that male territory characteristics do no longer have a substantial influence on mate choice.
We also include the territories' progress towards their ideal performance and consider how this ideal scenario can be achieved taking into account the territories' characteristics.
But strategic ventures into forbidden territory are characteristic of his monthly scholarly journal, Yanhuang Chunqiu.
When habitat quality varies at a small spatial scale habitat-specific demography and its contribution to population growth may be estimated on the scale of individual territories by linking territory-specific demography with territory habitat characteristics [e.g. 16,31].
Further, there are no reports of males fighting over territories, another characteristic of lekking behavior.
At times this revisiting of characteristic territory seems almost dutiful, yet the book includes some very fine writing.
