Ecological succession is the process of change in the species that make up an ecological community over time. ... Emergent plant life, or pond pioneers, ...
However, in smaller water bodies such as a pond the succession is easily recognizable. Different plant communities occupy different zones in a water body and exhibit concentric zonation. The edges of the water body are occupied by rooted species, submerged species are found in the littoral zone and plankton and floating species occupy the open ...
Phytoplankton and zooplankton communities in lake systems undergo seasonal succession in relation to nutrient availability, predation, and competition. Sommer et al. [ 20 ] described these patterns as part of the Plankton Ecology Group ( PEG ) model, with 24 statements constructed from the analysis of numerous systems.
The cyclic model of succession was proposed in 1947 by British ecologist Alexander Watt.In a seminal paper on vegetation patterns in grass, heath, and bog communities, [4] Watt describes the plant community is a regenerating entity consisting of a "space-time mosaic" of species, whose cyclic behavior can be characterized by patch dynamics.
There are three basic types of freshwater ecosystems: Lentic (slow moving water, including pools, ponds, and lakes), lotic (faster moving water, for example streams and rivers) and wetlands (areas where the soil is saturated or inundated for at least part of the time).
The park is tilted to ensure water can slowly trickle down to a 480,000-gallon retention pond at the bottom, providing extra storage space to absorb heavy rains. When it’s not flooded, it can be ...
The concept of ecologic succession also applies to underwater habitats. If a space becomes newly available in a reef surrounding, haplosclerid and calcareous sponges are the first animals to initially occur in this environment in greater numbers than other species. These types of sponges grow faster and have a shorter life-span than the species ...
The town of Ashburnham voted to remove the Whitney Pond Dam in 2018. Now, officials are in need of $1.2 million to make the project happen. ... Susie Bresney, a Mass Division of Ecological ...
