Biome

Biomes are a semi-distinct region with similar biological profile. For instance, Temperate Forest or Scrubland. Knowing the biome of a creature helps one determine where it should appear.

Land Biomes

• Plains/Steppe
• Forest
• Swamps
• Arid/Desert
• Beach/Island
• Urban (see below)
• Rural/Cultivated
• Ice Sheet
• Cave†

† Caves tend to be very sparse on Earth, but any sci-fi/fantasy shenanigans may allow a cave to be verdant and biologically active.

Urban Environments

This region is defined by mesa/cliff vertical structures and usually, an abundance of sophonts and food.

Exotic Analogues

An Exotic Analogue in this case is a biome that works in a somewhat similar fashion to an ordinary biome, but is a lot stranger. For instance, you could have Biome: Macrofauna Organs (Swamp/Wetlands Analogue), or Biome: Ancients Temple-Market (Urban Analogue)

The "Pet/Cultivated" Biome

Some creatures, through breeding, biotech, or losing their defenses over millennia. A creature with the "pet" biome has a biological niche so small that it's likely doomed outside of it. Note that not all creatures that are kept as pets (or food) are unviable species--even a common housecat can be devastating to populations of rodents and small birds. See "Invasive Species " on the Traveller Bestiary page.

Aquatic Biomes

• River/Lake
• Reef/Coastal
• Kelp Forest
• Ice Sheet
• Open Ocean
• Ocean Floor
• Ocean Vents

Exotic Biomes

• Volcano/Magma
• Macrofauna/Superorganism(†?)
• Gas Giant
• Nebulae†
• Psychic Realms†
• Data Streams†
• Asteroids†

Notes

• The dagger "†" indicates a "Loose" Sci-fi concept. This is the science fiction equivalent to "cinematic" in GURPS.
