Definition

1. Noun (Danh từ):
   • Association (in biology/ecology): A group of plants or animals of different species living together in a specific habitat, forming a recognizable ecological unit with a distinct structure and composition. It is a fundamental concept in phytosociology (plant sociology) and ecology.

Usage Examples

• Noun:
  • Các nhà sinh thái học nghiên cứu quần hợp thực vật ở vùng đầm lầy. (Ecologists study the plant association in the marshland area.)

  • Sự thay đổi khí hậu có thể phá vỡ cấu trúc của một quần hợp sinh học.* (Climate change can disrupt the structure of a biological association.)

Advanced Usage

• The term "quần hợp" is highly specialized and is almost exclusively used in scientific contexts, particularly in ecology, biology, and environmental science. It is not used in everyday conversation.
• It describes a specific, stable, and recurring grouping of species, often bearing the name of the dominant species (e.g., - Melaleuca association).

Variants and Related Words

• Quần xã (Community): A broader ecological term encompassing all the interacting populations of different species in a given area. A quần hợp is often considered a subunit or a specific type within a quần xã.
• Hệ sinh thái (Ecosystem): An even broader term that includes both the biological community (quần xã) and its physical environment.

Synonyms

• Tập hợp sinh vật (Biological assemblage): A more general term for a collection of organisms.
• Nhóm loài (Species group): A simple term for a group of species.

Notes on Different Meanings

• "Quần hợp" is a scientific term with a single, precise meaning. It should not be confused with the more common word "hợp quần", which is a verb meaning to gather, assemble, or unite into a group (e.g., - to unite to fight).
