The main hormones that play a part in blood glucose regulation are insulin and glucagon which are in a negative feedback loop. This means when there is an excess of one hormone and blood glucoses is going up/down too much, then the counter hormone is released.

Examples: Building nests, guarding, carrying, huddling, grooming and teaching their young - https://www.ck12.org/book/ck-12-biology-advanced-concepts/section/14.16/ and https://academic.oup.com/book/25631/chapter/193032576

Oxytocin(OT) and arginine vasopressin (AVP)

OT aids in labour and delivery alongside lactation. It is made in the hypothalamus

Arginine vasopressin aids in reabsorption of water in the kidneys, this aids in the scenting behaviour of many animals

Territorial and aggressive behaviours:

Animas like wolves and bug cats scent mark their territory with hormones and birds produce bird songs to warn other animals away.

Ghrelin is the hormone that detects the animals hunger. It is known as the “hunger hormone”.

Aggression:

Stags tend to fight other stags so they get the females. Hormones like testosterone play a large part in this.

Estradiol

2023-11-07 10:08:07 UTC

Steroid sex hormone involved in the menstrual cycle. Responsible for fat distributions and aids in the development of mammary glands, uterus and vagina during pregnancy.

Nesting

Triggered by ovulation

Estradiol

Progesterone

Prolactin

Wild animals nest in low sheltered spots which provide protection against predators and competitors that mean to exploit or kill offspring. https://www.sciencedirect.com/science/article/abs/pii/S0277539518304199

Animals release the hormone cortisol when they are stressed.

Glucocorticoids are se created by vertebrates in response to unpredictable and noxious stimuli.

The hormones testosterone, oestrogen and progesterone influence mating behaviour.

Signals are created outside of the body and these are called pheromones and help animals communicate in the wild.

testosterone helps the development of sperm and male characteristics.

Estrogen and progesterone helps the development of eggs and female characteristics.

Hormones regulate homeostasis and enhance important traits in animals. They include fertility , growth , development , health.

After an animal has feed, then the blood glucose start rising in the animal until it get dangerously high. Then pituitary gland sends a hormone to the pancreas which then secretes insulin and the liver coverts glucose into glycogen. This causes blood glucose levels to down. When the glucose levels get to low then the pituitary gland stops the insulin being produced and starts producing glucagon which causes glycogen to start being turned back into glucoses which can be released into blood stream which then increase blood glucose levels. This cycle continues until the animal starts to feel Hungary and feeds again.
