when environmental conditions are favourable (e.g. during colonization stages),
but are not regular polytocous species (e.g. mountain goat). There are no clear
patterns for the distribution of polytocous species among body weight, biomes, ...

Cooperative Breeding in Mammals
Fourth, whereas nonoffspring nursing tends to occur more often in monotocous
species when social group size is large, in polytocous species it is most common
when group size is small and decreases significantly as group size increases.

The Dasyurinae are characterised, in so far as they have been studied, by a
chromosome number of 2n «= 14, polytocous monoestrous or polyoestrous
reproduction, multiple mammae, and yolk-sac placentation. The pouch is
reasonably well ...

Ovulatory cycles of birds in general, and of domestic chickens in particular, are
not comparable to the reproductive cycles of vertebrates which are either above
or below birds on the evolutionary scale. In most polytocous vertebrates, groups
of ...

Because expulsion of fetal membranes occurs during labor in polytocous species
(produces multiple young at birth), stage 3 actually begins in stage 2 for dogs.

In some polytocous species (e.g., in Squalus acanthias; Koob and Callard, 1982),
several embryos lie in a single large compartment. In other polytocous species,
single embryos are in each compartment, and adjacent compartments are ...

Phylogenies and the Comparative Method in Animal Behavior
In polytocous taxa (modal litter size greater than one), by contrast, non-offspring
nursing was more common, was not considered milk theft, and decreased with
increasing group size. Surprisingly, one can draw a parallel between Ridley's
work ...

pattern was used also as a cytological landmark for identification of the physical

Advances in Ecological Research
One prediction is that the greater reproductive potential of polytocous species
can generate stronger, and less linear, density‐dependence in reproduction
compared to mono- tocous species (Andersen and Linnell, 2000; McCullough,
1997; ...
