Study Notes
Ecology
- Ecology is the study of factors controlling the distribution and abundance of species.
Omani Habitats
- Jidda (gravel plains): Dominated by Acacia ehrenbergiana (Salam) with a massive root system trapping windblown soil. It collects rainwater, but is drought-resistant.
- Sand dunes (Rub Al-khali and Wahiba): Prosopis cineraria (Ghaf) has deep roots reaching groundwater, making it drought-tolerant. Acacia tortilis (Samur) and A. nilotica (Qarat) are also present.
- Batinah coast: Wetter and more humid areas.
- Wadis: Areas with water. Ziziphus (Sidr) trees have massive trunks and roots for water access. Sideroxylon (Buut) is found on steep mountain slopes. Olive and juniper trees are in high-altitude areas with cold nights.
Factors Affecting Species Distribution
- Climate: Influences species distribution. Red kangaroos inhabit hot, arid, lowland deserts.
- Dispersal: Ability of organisms to move. Slow-moving animals (snails, worms) have limited dispersal. Flying animals (birds, insects) have greater dispersal capability. Plants dispersed by wind also have good dispersal.
- Behavior: Animal behavior affects distribution. Some insects or animals prefer one food source (e.g. mosquitos in the lab).
- Herbivory: Herbivores (sea urchins, limpets) can influence plant distribution (e.g., seaweed).
- Predation: Invasive species (brown tree snakes) can affect native animal populations.
- Parasites/Pathogens: Invasive pathogens (chestnut blight) can decimate populations introducing diseases.
Brackish Water
- Brackish water is where freshwater and saltwater meet.
