The Texas Blackland Prairies are a temperate grassland ecoregion located in Texas that runs roughly 300 miles (480 km) from the Red River in North Texas to San Antonio in the south. The prairie was named after its rich, dark soil. [3] Less than 1% of the original Blackland prairie vegetation remains, scattered across Texas in parcels. [4]
Artificial reefs can help increase biodiversity in an area. Artificial reef structures (ARs) have a variety of intended uses, ranging from the protection, enhancement and restoration of marine ecosystems [6] to the support of human activities like fishing, recreational diving and surfing. [23]
An ecosystem engineer is any species that creates, significantly modifies, maintains or destroys a habitat. These organisms can have a large impact on species richness and landscape-level heterogeneity of an area. [1] As a result, ecosystem engineers are important for maintaining the health and stability of the environment they are living in.

Arctic food webs are considered simple, meaning there are few steps in the food chain from small organisms to larger predators. For example, pteropods are "a key prey item of a number of higher predators – larger plankton, fish, seabirds, whales".
But California’s water supplies have been scrutinized amid the fires — especially after some fire hydrants in the city ran dry as firefighters battled the flames, and the pressure for what ...
The head is the largest part of the body, and bears four pairs of appendages. Two pairs of well-developed antennae are used to swim through the water. In addition, there are a pair of mandibles and a pair of maxillae. The thorax has three primary pairs of appendages.
The insects rely on water in which to breed and the first line of control is to reduce possible breeding locations by draining marshes and reducing accumulations of standing water. Other approaches include biological control of larvae by the use of fish or other predators , genetic control, the introduction of pathogens, growth-regulating ...
