Who is studying animals in the wild considered to be somewhat experimentally out of control

KIM [24]

Studying animals in the wild is considered somewhat experimentally out of control because of several reasons.

Explanation:

Study of wild animals can be done using several methods but none will be as effective as studying captivated animals. Using stationary cameras is a method to observe animals in the wild. The stationary nature of the camera makes it necessary for the animals to appear within the field of the camera.

This is difficult in places of low animal density. In addition to that placing camera at a longer distance to watch a larger area decreases the resolution of the images. When it comes to shallow water systems, the field imagery used to track the aquatic species frequently gets affected by issues like sun flicker.

Unmanned aerial vehicles can also be used to track and study animals in the wild. This is good alternative but filming through dense canopies or turbid water is a limitation. Bio loggers can also be used for animal tracking but it is limited by weight since it has to be carried by animals.

Breeding livestock is graded "superior," "average," and "inferior" on the same traits as slaughter animals. In a 50-word paragra

BaLLatris [955]

Livestock producers and breeders rank livestock on their ability to produce high quality, efficient breeding animals and market-worthy offspring.

To be able to effectively evaluate breeding and market animals is of vital economic importance for the animal markets. The same traits used to evaluate high-grade slaughter animals are also important in the grading of breeding stock.

When we judge livestock we classify them as:

Superior livestock
Average livestock
Inferior livestock

We are looking for the most desirable traits to fit our particular market and genetic needs. The "Livestock Judging Manual" indicates that some of the most prevalent traits necessary to score a better rating are:

Live weight
Fat depth
Muscling

and many more. The most important of which is muscling given that an animal with more muscle will produce more desirable meat for the average consumer, and therefore can be sold at higher prices.
