xerosere
RareTechnical / Scientific
Definition
Meaning
The ecological sequence of plant communities that develops on a dry or arid surface, from pioneer species to climax vegetation.
A type of primary ecological succession that occurs specifically in dry, water-deficient environments with low moisture availability, such as rocks, sand dunes, or exposed soils.
Linguistics
Semantic Notes
Derived from 'xero-' (dry) + 'sere' (a stage in ecological succession). The term is confined to ecology and biogeography, specifically describing the developmental stages of a plant community in an arid starting environment. It is a hyponym (specific type) of 'sere' or 'primary succession'.

Examples
By Part of Speech
adjective
British English
- The xerosere process is slower than a hydrosere.
American English
- Xerosere succession is a key concept in desert ecology.
Examples
By CEFR Level
- The textbook described how a xerosere begins with lichens on bare rock.
- Researchers compared the biomass accumulation rate in a coastal dune xerosere with that of a hydrosere in a nearby estuary.
- The classic model of a lithosere, a xerosere starting on rock, involves distinct seral stages from crustose lichens to a potential woodland climax.
Learning
Memory Aids
Mnemonic
Think: 'XEROX' machines are often associated with dry processes (toner powder). 'XEROsere' is the dry-ecological-process.
Conceptual Metaphor
SUCCESSION IS A JOURNEY (a xerosere is a specific, dry path that a landscape takes from barren to forested).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Не путать с просто 'сукцессией' (succession). Xerosere — более узкий термин, означающий именно первичную сукцессию в *сухих* условиях.
- Прямого однословного эквивалента в русском может не быть. Часто переводят описательно: 'первичная ксерогенная сукцессия' или 'ксеросери́я'.
Common Mistakes
- Misspelling as 'xeroscere', 'zerosere', or 'xeroshere'.
- Using it as a general term for any succession, rather than specifically for dry-site succession.
- Confusing it with 'psammosere' (succession on sand), which is a type of xerosere.

FAQ
Frequently Asked Questions
It is a specific type of primary succession. All xeroseres are primary successions, but not all primary successions are xeroseres (e.g., a hydrosere starts in water).
The direct antonym is a hydrosere, which is an ecological succession that begins in a body of water or very wet environment.
The colonization and gradual development of plant communities on a newly formed volcanic lava flow (which is dry and sterile) is a classic example of a xerosere.
It is a highly specialised term within the technical field of ecology. Outside of academic or professional contexts in environmental science, there is virtually no need to use it.
