FRQ: Ecology Question Ecological succession from a pioneer community to a climax community is an easy process to understand once you know each step. Ecological succession is the transition in the species composition of a biological community‚ often following ecological disturbance of the community. There are two types of ecological succession‚ primary and secondary. Primary succession is the establishment of a biological community in an area virtually barren of life‚ where there were originally

Marine or saltwater‚ which includes oceans‚ seas‚ estuaries‚ coral reefs and saltwater wetland. Each of these aquatic ecosystems can be defined by variables such as temperature‚ the presence or absence of light‚ and the availability of nutrients. Aquatic biomes cover almost all the world (around 75% of the surface) and only 3% of them are freshwaters. Freshwater ecosystems This ecosystem is defined as having a low salt concentration of less than 1%. It helps to make up all the different animals’ life

CHAPTER 1 INTRODUCTION‚ OBJECTIVES AND OUTLINE OF THE THESIS -49- -50- Abstract As marine environments are under increasing anthropogenic pressure‚ there is a need for decision support systems (DSSs) and management tools that allow to tackle some of the environmental problems associated with this pressure and to allocate the different uses in a sustainable way. Most marine management tools are built around the Driver-Pressure-StateImpact-Response (DPSIR) framework‚ where indicators

told‚ the food we eat‚ the timber we cut‚ and the water we draw amounts to an astounding one-third to one-half of global ecosystem production. But humans are part of nature‚ and like every other species on the planet‚ we depend upon healthy ecosystems for our survival. Nature provides us essentials like clean water‚ food‚ medicines‚ even recreational retreats. Intact ecosystems also help regulate our weather and climate. But these systems are extremely fragile‚ and we’re only now beginning to understand

human interference due to its proximity to heavy traffic‚ therefore meaning that plant species have a lot of freedom to grow and spread. This in turn then encourages an increase in plant‚ bird and animal life along the routeway‚ creating a diverse ecosystem - such as along the M4 corridor‚ which has become a home to kestrels and other birds of prey due to the increase in the number of insects and small mammals who inhabit the area. In addition‚ some human activities along routeways can affect the types

Coastal environments especially benthic ecosystems are exposed to several anthropogenic and physical disturbances‚ which can affect burrowing organisms (C. kraussi) and other marine benthic species on several biological scales. Organisms that are sensitive to the human disturbances can either die or be displaced while those that remain might be facilitated. These disturbances can result in changes in population and a shift in ecological processes which could ultimately lead to the decrease of biodiversity

becoming invasive. The feral pigs in Hawaii were intentionally introduced by Polynesian explorers. When Polynesians returned to Hawaii‚ the settlers had something to hunt and eat. Since the pigs’ arrival‚ they have caused destruction to Hawaii’s ecosystem. These pigs’ appetites and trampling nature to trees and vegetation is a disturbance‚ which led to the invasion of strawberry guava and the migration of the native Hawaiian birds to higher elevation.

length and can be used as whips to scare off predators. They can also break off their tails if caught and will grow another tail without any previous permanent damage. Some other members of the iguana family include the Fiji Island banded iguana‚ the desert iguana‚ and the Galápagos Islands marine iguana. Their looks‚ actions‚ and threatened rankings differ from species to species. Due to Florida’s height in the exotic pet trade‚ iguanas given to us as pets have escaped or been released into the wild
