Spanish Forest Ecosystems
Deciduous Forests and Heathlands
Deciduous Forest
Tall trees with smooth, straight trunks and large leaves that fall in autumn. These trees often form large masses. They tolerate heat and cold well, requiring high humidity. They thrive in limestone and siliceous soils, particularly in the Cantabrian Mountains and Pyrenees of Navarre. Their fast-growing, high-quality wood is used for furniture and utensils.
Tree Mountain
This species prefers limestone and siliceous soils and grows quickly. Its wood is

Culture Media Preparation
According to the presentation: Dew refers to single-phase (solid, semi-solid, and liquid) and two-phase media.
General Technique for Preparing Culture Media
- Weighing: Carefully weigh the extract components or commercial dry media on a watch glass or in a beaker (depending on the quantity).
- Hydration: Add the required volume of distilled water.
- Dissolving: Stir the mixture in distilled water and heat to boiling. Maintain boiling for 1 to 2 minutes.
- pH Adjustment: Check the pH
Key Ecological Concepts: Cycles, Pollutants, and Factors
Wilson Cycle and Supercontinents
The Wilson Cycle proposes that every 400-500 million years, all land masses join together to form a supercontinent. Pangea was the last supercontinent, and it is currently disintegrating. Before Pangea, there was likely another supercontinent called Pannotia. This cycle is related to the Hercynian orogeny, which was important in forming the oldest reliefs in the Iberian Peninsula.
Water Pollutants
Water pollutants include any living organisms, chemicals, or forms of

Wastewater Treatment: An Overview
Wastewater treatment is a crucial process divided into several stages to remove contaminants and make water safe for reuse or discharge. This document outlines the key stages involved.
Pre-treatment
Pre-treatment serves to regulate and measure the flow into the plant, extract large floating solids and sand. This stage uses equipment such as grilles and screens. The plants are designed to treat a specific volume of water. Pretreatment steps include:
- Entry and Elevation
Formation of Accretionary Prisms & Orogenic Belts
Training Ranges: Formation of Accretionary Prism
K carries sediment. Oceanic lithosphere subducting, not the majority. The front of the continental shelf traps sediments, which are folded and fractured, thus causing the accretionary prism.
Magmatism and Metamorphism
The presence of water in the subducting lithosphere and heat generated by the friction between plates favor the partial fusion of rocks. The magmas originated climb, and those that remain inside contribute to the thickening of the continental

Sanitary and Toxicological Aspects of Fish
Toxicity and Intoxication
Freshly caught fish muscle is sterile. The presence of pathogenic germs is related to their presence in water or sediments. Contaminants include pathogenic bacteria like Vibrio parahaemolyticus and Clostridium botulinum.
Viral Infections
The presence of viruses is considered a potential risk, and they have been shown to survive for long periods in refrigerated and frozen mollusks.
Parasitic Diseases
Some parasites affecting fish can
