Domestic Dogs

Domestic dog is morphologically distinct from all other canids except its close relatives, the wolf-like canids. The earliest burial remains of a domestic dog are 14,000 years old and were found in Bonn-Oberkassel, Germany. Despite their many shapes and sizes all domestic dogs, from Newfoundlands to pugs, are members of the same species-Canis familiaris. Although they have domestic temperaments, these dogs are related to wolves, foxes, and jackals. Many of the behavior traits and body movements or positioning can be applied universally to all canids for example ear positioning, tail positioning, raised hackles, etc. There is considerable similarity between dogs and wild canid species; many wolf-like canids cannot be distinguished from domestic dogs of equivalent size. However, all dogs are consistently separated from fox-sized, wild canids by subtle but evolutionarily significant differences in olecranon, metapodial, and scapula morphology. Second, in domestic dogs the pattern of static allometry is nearly identical to that of ontogenetic allometry. This finding can be attributed to simple heterochronic alterations of postnatal growth rates. Talking about wolves, they have a fairly sophisticated communication system--in both body language and verbal language. ...

Summary

Dogs are relegated as canids. Canids also include Wolves, Foxes, Jackals, and Dingoes. The domestic dog is an extremely close relative of the gray wolf, differing from it by at most 0.2% of mitochondrial DNA sequence. In comparison, the gray wolf differs from its closest wild relative, the coyote, by about 4% of mitochondrial DNA sequence…

Oxygen Saturation
My control variables were the temperature of the water, and the pH level of the water. Other, un-measureable variables included the main food supply and natural predators of the gammarus pulex. The Kick-Sampling method was used in this experiment and was found to be effective in accurately determining the number of shrimps at a specific site. Due to my findings, I have concluded the null hypothesis to be false. The number of shrimps per site is directly related to the dissolved oxygen content of said site.

Cultural References in Translation
What makes people a group are not only the affinities of its members, but rather the diversity its members have towards what stands outside of it: the action of culture is similar to the two faces of a wall, which both encloses and, on the other side, protects from what is unknown and obscure, from what is foreign. And the language is the most important (and most efficient) wall a group have to protect its society, its structures and its culture.

Ordinary people care for their dogs as if they're caring for their own children, sleeping, eating and even traveling with them.

Keystone Species
The populations of big-cat prey including the red coati (Nasua nasua), the agouti (Dasyprocta variegata), and the paca (Agouti paca) are about ten times higher than on Cocha Cashu, Peru, where big cats still live. However, this increase may result from natural population variability rather than the lack of jaguars and pumas. The extreme removal of herbivores and frugivorous mammals would drastically affect forest regeneration, altering tree species composition, but the effects of modest changes in densities are less clear.
