What are Biogeochemical Cycles?
0 Views •
2019
The most common elements in organic molecules, carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus, are only available in the ecosystem in limited amounts. Therefore, these nutrients must be recycled through both biotic and abiotic components of the ecosystem, in processes generally called biogeochemical cycles. Biogeochemical Cycles and Decomposition The matter that makes up living organisms, like water, carbon, nitrogen, sulfur and phosphorous, exist in limited quantities within the...

The Phosphorus Cycle

2019
Unlike carbon, water, and nitrogen, phosphorus is not present in the atmosphere as a gas. Instead, most phosphorus in the ecosystem exists as compounds, such as phosphate ions (PO43-), found in soil, water, sediment and rocks. Phosphorus is often a limiting nutrient (i.e., in short supply). Consequently, phosphorus is added to most agricultural fertilizers, which can cause environmental problems related to runoff in aquatic ecosystems. Biological Phosphorus Cycle Phosphorus is present in many...

Using Topographic Maps to Generate Topographic Profiles

Source: Laboratory of Alan Lester - University of Colorado Boulder Topographic maps are "plan-view" representations of Earth's three-dimensional surface. They are a standard type of map-view that provides an overhead, or aerial, perspective. Among the defining features of a topographic map are the contour lines that indicate locations of constant elevation. The elevation interval between the contour lines is dependent on the level of detail provided by the map and the kind of topography present.

The Sulfur Cycle

2019
Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...
FAQs
Converging plates and crustal compression can thicken or deform the crust, while fault activity can raise particular blocks of rock. Buoyant forces from the mantle provide another mechanism for elevation. Although these processes differ geologically, each can produce higher terrain such as mountains or plateaus, creating new physical settings for biological communities.
Higher terrain creates environmental gradients that can change climate, soil development, and water availability over relatively short geographic distances. These gradients divide landscapes into contrasting habitats and influence where species can survive. As conditions vary with elevation, populations may experience different ecological pressures, contributing to distribution patterns and adaptation.
When uplift raises or tilts land, water flow can be reorganized across the landscape. New drainage patterns affect where water is available and interact with erosion and soil development. These changes can modify habitat conditions and connectivity, influencing how terrestrial ecosystems develop and how organisms are distributed across the altered terrain.
Uplift creates contrasting elevations, climates, soils, and water conditions within a broader landscape. Biologists can relate these environmental differences to patterns of biodiversity and endemism, meaning species restricted to particular areas. Such comparisons help reveal how changing terrain and habitat conditions shape where species occur and why some biological communities become geographically distinctive.
By producing environmental gradients, uplift exposes populations to differing climates, water availability, soils, and elevations. These contrasts provide biological context for examining adaptation, because populations living in separate conditions may face different ecological pressures. The resulting distribution patterns can help connect landscape change with the long-term adjustment of organisms to their environments.
Uplift changes terrain while erosion and soil development progressively reshape the available environment. These interacting processes provide a setting for examining ecological succession, the change in biological communities over time, and the long-term evolution of terrestrial ecosystems. Researchers can therefore connect geological landscape change with shifts in habitat structure and biological composition.
