Sumado a lo anterior, los autores concluyen que la homogeneidad vegetacional y microclimtica de los humedales boscosos, crean condiciones ptimas para el desarrollo tanto de la entomofauna, como de otros grupos faunsticos, actuando como concentradores y reservorios de gran parte de la biota local (Solervicens & Elgueta 1994). Many tide pool habitats are home to especially adaptable animals that have engaged the attention of naturalists and marine biologists, as well as philosophical essayists: John Steinbeck (2016, December 04). Many plants and animals in these ecosystems have adaptations to help them cope with the force and the different conditions that running water brings.

WebFyke nets are operated like pots, set one by one in the littoral zone, from one to ten meters depth, and are usually moved to another spot after retrieval, usually on a daily basis. The intertidal zone or littoral zone is the term used to describe the seashore which is covered during high tide and exposed during low tide, revealing a unique biome which survives under such fluctuating conditions. Coastlines are dynamic, high energy, and geologically complicated places where many different erosional and depositional features exist (see Chapter 5).They include all parts of the land-sea boundary directly affected by the sea, including land far above high tide and seafloor well below normal wave base.
