Taxonomy01:31

Taxonomy

81.6K
Taxonomy is the science of defining and naming groups of biological organisms based on shared characteristics. It uses a hierarchy of increasingly inclusive categories with Latin names. The smallest units of taxonomy, species and genus, are used to assign a formal, taxonomic name to each species in a system. This classification system, referred to as binomial nomenclature, was formalized by Carolus Linnaeus in the 18th century.

Instinctive Drift01:05

Instinctive Drift

369
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

Conservation of Declining Populations02:07

Conservation of Declining Populations

10.0K
Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Stability of structures01:14

Stability of structures

272
In mechanical engineering, the stability of systems under various forces is critical for designing durable and efficient structures. One fundamental way to explore these concepts is by analyzing systems like two rods connected at a pivot point, O, with a torsional spring of spring constant k at the pivot point. This system is similar in appearance to a scissor jack used to change tires on a car. In this case, the arms of the linkage (equivalent to the rods in this system) are entirely vertical,...

Nursing Interventions I: Taxonomy of Nursing Interventions

3.1K
Nursing interventions are chosen as part of the planning process to achieve patient outcomes. Once nursing diagnoses are determined, the goals and outcomes are specified, then the nursing interventions are selected and individualized according to the patient's situation.
A nursing intervention is a treatment or action based on scientific concepts and knowledge from the nursing, behavioral, and physical sciences. Identifying and prioritizing nursing interventions based on the desired outcome...

Classification of Illness01:17

Classification of Illness

8.1K
The meaning of illness is individualized to each person who experiences an alteration in health. In contrast, disease is a medical term indicating a pathological change in the structure and function of the body or mind. It is a condition that has specific symptoms and boundaries.
An illness is a response to a disease in which the person's level of functioning is changed compared with a previous level. The general classification of illness includes acute and chronic.
Acute illness is severe...

Summary

Taxonomy is not declining but evolving. Analysis shows increasing species descriptions, authors, and interdisciplinary research, indicating new research methods rather than a decline.

Area of Science:

  • Systematic Biology
  • Biodiversity Research
  • Scientific Classification

Background:

  • Literature suggests a decline in taxonomic research.
  • Analysis of Zoological Record data (1864-2010, 1978-2010) challenges this notion.
  • Focus on the scientific inventory and classification of Earth's living taxa.

Discussion:

  • The number of authors describing new species is increasing.
  • The quantity of articles detailing new species discoveries is also rising.
  • A growing trend in interdisciplinary approaches within taxonomy is observed.

Key Insights:

  • Contrary to popular belief, taxonomy is not in decline.
  • The number of newly described species shows an upward trend.
  • Taxonomy is adapting through new research methodologies and collaborations.

Outlook:

  • Further exploration is needed to understand the evolving research modalities in taxonomy.
  • The field's capacity to meet its objective of global taxa inventory is questioned.
  • Shifting focus from 'decline' to 'inadequacy' relative to objectives is proposed.
