Examples of studying animal behavior

1. Fabre’s research on insects

Fabre was the first scientist to use observation methods to study the life of insects. He spent a lot of time observing each insect, such as observing bumblebees for 20 years, earth gall transitional metamorphosis for 25 years, tunnel wasps for 30 years, and dung beetles ( Shit kills beetles) for 40 years before finally writing a piece of material.

When a dung beetle finds a pile of feces, it uses its legs to shape part of the feces into a ball and roll it away. It hides the dung balls first and then eats them. Dung beetles also provide food to their young in this way. A breeding pair of dung beetles will hide a ball of dung, but the female will use soil to shape the ball into a pear shape and lay her eggs in the neck of the pear-shaped ball. Once the larvae hatch, they feed on fecal pellets. By the time the dung balls are eaten, they have grown into adult dung beetles and emerged from the soil.

2. Frisch’s research on bee color vision

If you believe in bee color blindness, you are undoubtedly admitting that the bright colors of flowers have no attraction to bees for pollination. So he conducted a series of simple experiments using color cards, proving that bees can indeed distinguish different colors.

3. Tinbergen’s study on the food-seeking behavior of herring gull chicks

The behavior of young herring gulls pecking at their parents for food is caused by the red spots on their parents.

4. Lawrence’s research on the learning behavior of small wild geese

animal behavior research methods

1. Observation method: Observe various behaviors of animals on the spot in the wild in their natural state.

Features: Do not exert any external influence on it or reduce the influence to a minimum, record accurately, carefully and truly.

2. Experimental method: Apply varying degrees of external influences to the research object, and then observe the behavior of the animal.

Features: Emphasis on changing the living conditions of animals according to the needs of the research goals and observing animal behavior in the changed environment.

Animal behavior research PPT, the third part: training to meet standards

1. The main methods of studying animal behavior are ________ and _____.

Zoologists use cameras to secretly record the living conditions of deer in the forest. This research method belongs to _____; two young rabbits are placed together with another litter of young rabbits, and the body of one of the young rabbits is The research method of pre-smearing the urine of a "new mother" to see how the female rabbit recognizes her babies is _____.

A. Experimental method B. Observation method

2. The following is the experimental design of a student who is exploring "whether ants like sweets".

Materials and tools: a split bamboo tube (15cm long), an ant, a cup of concentrated sugar water, a cup of water, a magnifying glass, two droppers

Experimental steps:

① On both ends of the bamboo tube, use two droppers to drop a drop of concentrated sugar water and a drop of clear water respectively, and place an ant at an equal distance between the two drops of water. (As shown on the right)

② Use a magnifying glass to observe the feeding behavior of ants.
