Wide grazing and perusing by means of household and wild herbivores form the crops composition, constitution and dynamics of many terrestrial ecosystems. This quantity investigates how huge herbivores not just impact the constitution and distribution of the plants, but in addition impact nutrient flows and the responses of linked fauna.

Tsuda et al. (1997) similarly studied a large sample of dogs from Asia, but also included some samples from wolves. Consequently, they were able to convincingly demonstrate a close relationship between wolves and dogs. , 1997), but in this study an attempt to use the molecular information to estimate the date of domestication was made. The study by Vilà et al. included 162 wolves from 27 populations from throughout Europe, Asia and North America and 140 dogs representing 67 breeds. As Okumura et al.
3). 34 P. Savolainen Thus, a ﬁrst origin of dog mtDNA clade A, a long time before the origin of dog clades B and C, does not seem probable considering the very similar proportions of clades A, B and C around the world. The total sum of circumstantial mtDNA evidence therefore indicates a single origin, in both place and time, for the three clades, approximately 15,000 years ago. Furthermore, in the absence of a clear result from the mtDNA data, the best evidence for the time of the ﬁrst origin of the domestic dog remains the archaeological record, which indicates an origin approximately 15,000 years ago.
