Mate Choice01:20

Mate Choice

11.9K
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.

The Auditory Ossicles01:11

The Auditory Ossicles

3.6K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Natural Selection and Mating Preferences01:06

Natural Selection and Mating Preferences

676
The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.
Females, due to their biological roles in conception, pregnancy, and nursing,...

The Mammary Glands

2.6K
The female breast is a hemispheric projection of variable size positioned anterior to the pectoralis major and serratus anterior muscles. A fascia layer composed of dense, irregular connective tissue connects it to these muscles.
Each breast features a pigmented projection known as the nipple, through which milk emerges via closely spaced openings of ducts, referred to as lactiferous ducts. Surrounding the nipple is a circular pigmented area of skin named the areola, which appears rough due to...

The Menstrual Cycle01:19

The Menstrual Cycle

5.5K
The menstrual cycle is a recurrent sequence of changes in the uterine endometrium, specifically its functional layer, the stratum functionalis. This cycle prepares the uterus for potential pregnancy. This cycle typically spans 21–35 days, averaging 28 days, and aligns with the ovarian cycle, regulated by fluctuating levels of ovarian hormones, primarily estrogen and progesterone.
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a...

Relationship Formation

46.3K
What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Summary
This summary is machine-generated.

Keystone species, like starfish, are crucial for maintaining ecosystem diversity. Removing them causes ecosystem collapse, a principle applicable to human impact on the planet.

Area of Science:

  • Ecology
  • Conservation Biology
  • Environmental Science

Background:

  • Keystone species play a disproportionately large role in maintaining the structure of ecological communities.
  • The removal of keystone species can lead to dramatic shifts in ecosystem composition and function.
  • Examples include starfish in tide pools, sea otters in kelp forests, and wildebeest in the Serengeti.

Purpose of the Study:

  • To illustrate the ecological principle of keystone species using well-known examples.
  • To draw parallels between natural ecosystem dynamics and the impact of human activities on a global scale.
  • To prompt consideration of human influence as a dominant ecological force.

Main Methods:

  • Review of ecological case studies demonstrating keystone species effects.
  • Analogical reasoning to compare natural predation with human population growth and resource consumption.
  • Conceptual framework highlighting human impact on biodiversity.

Main Results:

  • The removal of keystone predators leads to a loss of biodiversity and ecosystem instability.
  • Human activities, unchecked by natural predation, are analogous to the unchecked proliferation of mussels in Paine's tide pool experiments.
  • This unchecked growth threatens global biodiversity and ecosystem health.

Conclusions:

  • Understanding ecological rules, particularly the role of keystone species, is vital for sustainable management.
  • Humans act as a 'keystone species' with a profound, often detrimental, impact on the global ecosystem.
  • Urgent consideration of human ecological impact is necessary to avoid a 'mussel-bound' world.
