Fundamental Concepts in Ecology and Biogeography

Ecosystem Structure and Energy Flow

Tidal Amplitude

The difference between the levels of high tide and low tide. This measurement varies based on depth, the volume of the water basin, and coastal morphology.

Gross Primary Production (GPP)

The total amount of energy fixed by autotrophic organisms (or organic matter produced) per unit of time.

Net Primary Production (NPP)

The quantity of energy or organic matter stored per unit of time, representing the remaining biomass after respiration.

Secondary Production

The amount of energy (or organic matter) fixed or assimilated by animals and other heterotrophic organisms.

Gross Secondary Production (GSP)

The total amount of energy absorbed by an animal per...

Solid Waste Classification by Composition

Solid waste, in terms of its composition, can be classified as follows:

Organic Wastes

This includes all waste of biological origin that was once alive or part of a living being. It is biodegradable, meaning it decomposes naturally and quickly. Examples include leaves, twigs, shells, food scraps, and fruit and vegetable remains.

Inorganic Wastes

This category comprises all non-biological waste. Due to their chemical characteristics, these materials undergo natural decay very slowly. Many are natural but not biodegradable, such as plastic containers, glass, and cans.

Hazardous Waste

This refers to any waste, whether organic or inorganic, that constitutes a potential hazard (e.g., flammable, toxic, reactive,...

Solid Waste: A Growing Global Problem

Solid waste poses a significant challenge for societies worldwide, particularly in densely populated urban areas. Overpopulation, increased human activity, and modern consumerism have dramatically increased the amount of waste we generate. Inefficient waste management practices, such as open burning and inadequate landfilling, lead to serious health problems and environmental damage. These include:

• Unpleasant odors from decomposing organic matter.
• Health risks due to uncontrolled accumulation, attracting disease-carrying rodents and insects.
• Soil, surface water, and groundwater contamination from leachate.
• Air pollution from controlled and uncontrolled combustion.
• Degradation of the landscape.

Many waste materials...

Animal Kingdom: Fundamental Characteristics

Animals are multicellular organisms that possess tissues, and their nutrition is heterotrophic, meaning they obtain nutrients by consuming other organisms.

Vertebrates: Animals with a Backbone

Vertebrates include:

• Fish
• Amphibians
• Reptiles
• Birds
• Mammals

They are characterized by having an internal skeleton that includes a vertebral column (backbone).

Invertebrates: Animals Without a Backbone

Invertebrates encompass a vast group, including:

• Porifera (Sponges)
• Coelenterata (Cnidarians)
• Worms
• Mollusks
• Arthropods
• Echinoderms

These animals may have an internal or external skeleton, or no skeleton at all, and they lack a vertebral column. They can be found in both freshwater and saltwater environments.

Porifera (Sponges):

Environmental and Territorial Geography

Natural Disasters

Natural disasters occur when nature destroys as a result of the action of elements like relief, climate, and water, such as earthquakes, volcanoes, hurricanes, and floods. Example: Floods in Valencia.

Deforestation

Deforestation refers to forest loss resulting from the creation of new open spaces for agriculture and livestock. It is also caused by the construction of infrastructure, acid rain, desertification, and forest fires. Example: Deforestation in Serra de Na Burguesa, Mallorca, caused by forest fires.

Natural Area of Special Interest (ANEI)

A Natural Area of Special Interest is a space declared for its unique natural values of wildlife or landscapes. In the Balearic Islands, these areas...

GOTHIC. Originating in Paris as the second international style, spanning the 12th to 16th centuries.

Historical and Intellectual Context

The Gothic period marked an intellectual evolution through the opening of humanism (influenced by Saint Thomas Aquinas) and naturalism (associated with Saint Francis of Assisi). The perception of God shifted from a strict judge to a more benevolent figure, while the center of thought expanded from solely focusing on God to embracing humanity and its creator. This philosophical shift deeply transformed painting and sculpture towards greater naturalism.

The Cistercian order, established by Saint Bernard of Clairvaux, regulated and disseminated the foundational aspects of Gothic art. They believed excessive architectural...

Atmosphere and Atmospheric Pressure

Atmospheric pressure: The weight of the air exerted on the Earth's surface. Air pressure is measured in millibars, which is why atmospheric pressure decreases rapidly with altitude. It also varies horizontally with latitude.

Geothermal variation: Variation of temperature, noting two points situated at an altitude difference of 100 meters.

Anticyclones: Regions of high pressure where air circulates, due to the Coriolis force, in the direction of clock hands in the Northern Hemisphere, and in the contrary direction in the Southern Hemisphere.

Depressions: Areas where air circulates in the opposite direction of clock hands in the Northern Hemisphere, favored by the Coriolis force. They usually bring bad weather,...

Earth's Composition: Rocks and Minerals

Many common minerals, such as calcite, are found within rocks, which originate from various geological processes. The Earth's crust is primarily composed of three main types of rocks:

• Igneous Rocks: Formed when magma cools and solidifies.
  • Extrusive: Expelled by volcanoes onto the Earth's surface.
  • Intrusive: Do not reach the Earth's surface, solidifying underground.
• Metamorphic Rocks: Formed deep within the Earth's surface under high pressure and temperatures.
• Sedimentary Rocks: Formed through a process involving:
  1. Erosion
  2. Sediment Transport
  3. Deposition
  4. Compaction

Common minerals found in various rock types include kyanite, staurolite, sillimanite, quartz, turquoise, and garnets. Examples of sedimentary rocks include...

The Origin of Life: Hypotheses and Evidence

The Panspermia Hypothesis

The hypothesis of extraterrestrial origin, known as Panspermia, proposes that the first organisms arrived on Earth from other parts of the universe, transported by meteorites. While this theory does not explain the ultimate origin of these beings, there is increasing evidence of organic matter arriving on Earth via meteorites.

Oparin's Hypothesis and Miller's Experiment

According to Oparin's hypothesis, the existing conditions on the early Earth allowed for the synthesis of a multitude of possible organic molecules. These molecules fell into the oceans, forming a nutrient broth or "primordial soup" where they accumulated. The affinity between larger and smaller molecules led...

Historical context: the Early Modern period

The period between the 15th and 18th centuries is known as the time of absolutism. Absolute monarchies organized administrative structures that, in many cases, undermined the power of the Church.

Two events were decisive for the birth of modern society:

• The Protestant Reformation, which favored modernity in Europe and broke the Catholic Church's monopoly in Western Europe. Protestantism promoted the reading of the Bible, which led to a process of literacy.
• The development of the printing press, which led to the organization of an educational system.

Modern society also began with Copernican astronomy. Copernicus replaced the geocentric view with a heliocentric one. His heliocentric model was incompatible...
