"Callimico" is a genus name in the family Callitrichidae, which includes various species of small, New World monkeys. The specific species that falls under this genus is "Callimico goeldii," also known as Goeldi's marmoset or Goeldi's monkey.

Goeldi's marmosets are native to the western Amazon Basin in South America, particularly in regions of Brazil, Colombia, Ecuador, and Peru. They have a distinctive appearance with a body size of about 8-12 inches long and weighing around 10-14 ounces. They have a brownish or grayish fur coat, with a naked face that has a white stripe running from the corner of their eyes to the corners of their mouths.

Goeldi's marmosets are omnivorous and feed on fruits, insects, small vertebrates, and exudates from trees. They are known for their highly social behavior, living in groups of 2-15 individuals. They have a complex communication system that includes vocalizations, facial expressions, and body postures.

In summary, "Callimico" is the genus name for Goeldi's marmoset, a small New World monkey species native to the western Amazon Basin in South America.

Ovulation detection refers to the process of identifying the time period during which an ovary releases an oocyte (mature egg) from its follicle, ready for fertilization. This is a crucial aspect of reproductive health and assisted reproduction technologies (ART), such as in vitro fertilization (IVF).

There are several methods to detect ovulation, including:

1. Ovulation Predictor Kits (OPKs): These are home-use test kits that detect the surge of luteinizing hormone (LH) in urine, which occurs 24-36 hours prior to ovulation.
2. Basal Body Temperature (BBT) Charting: This involves tracking and recording daily basal body temperature (the lowest temperature attained by the body during rest), as it tends to rise slightly after ovulation due to increased progesterone levels.
3. Hormonal Monitoring: Blood tests can be used to measure hormone levels, such as estrogen and progesterone, throughout a menstrual cycle to detect ovulation.
4. Transvaginal Ultrasound: This imaging technique is often used in clinical settings to monitor follicular development and determine the exact time of ovulation by observing changes in the ovarian follicle and endometrial lining.
5. Saliva Ferning Tests: A microscope is used to examine the patterns formed by dried saliva, which can indicate increased estrogen levels prior to ovulation.

Accurate ovulation detection helps individuals or couples trying to conceive optimize their chances of success and provides valuable information for healthcare providers in managing reproductive health issues.

Callitrichinae is a subfamily of New World monkeys that includes marmosets and tamarins. These small primates are known for their claw-like nails (called "tegulae"), which they use for grooming and climbing, as well as their small size and social behavior. They are native to the forests of Central and South America. Some notable species in this subfamily include the common marmoset (Callithrix jacchus) and the golden lion tamarin (Leontopithecus rosalia).
