Mangroves range in size from small bushes to the 60-meter giants found in Ecuador. Within a given mangrove forest, different species occupy distinct niches. Those that can handle tidal soakings grow in the open sea, in sheltered bays, and on fringe islands. Trees adapted to drier, less salty soil can be found farther from the shoreline.
Plants grow in aggregated formations which provide shelter from wind, and ice and also improve seed success. [1] Animals have adapted with specialized organs, such as a rete mirabile, an organ that efficiently transfers heat. Frogs and amphibians use "anti-freeze" to prevent organ damage while hibernating.
The soil there is frozen from 25 to 90 cm (10 to 35 in) down, making it impossible for trees to grow there. Instead, bare and sometimes rocky land can only support certain kinds of Arctic vegetation, low-growing plants such as moss, heath (Ericaceae varieties such as crowberry and black bearberry), and lichen.

Dominant features are hills and plains, ponds and lakes that allow growth of low shrubs mixed with herbs, lichens, and cotton-grass. Stunted Krummholz trees grow along the major river valleys. For almost a million square kilometres, the pattern of habitats in the Southern Arctic is the same: sprawling shrublands, wet sedge meadows, and cold ...
The top layer of the understory is the sub-canopy composed of smaller mature trees, saplings, and suppressed juvenile canopy layer trees awaiting an opening in the canopy. Below the sub-canopy is the shrub layer, composed of low growing woody plants. Typically the lowest growing (and most diverse) layer is the ground cover or herbaceous layer.
The majority of this land consists of irregular plains with low hills, which is made up of predominantly residuum and some loess on weakly developed soils. The climate of this region is an annual precipitation of 1,000–1,600 millimetres (39–63 in) and average temperatures of 13−19 °C. [ 1 ]
Flowering big bluestem, a characteristic tallgrass prairie plant. The tallgrass prairie is an ecosystem native to central North America.Historically, natural and anthropogenic fire, as well as grazing by large mammals (primarily bison) provided periodic disturbances to these ecosystems, limiting the encroachment of trees, recycling soil nutrients, and facilitating seed dispersal and germination.
Although in some sectors of landowners in the southeast learned over the years that the longleaf pine was a slow growing tree, and thus began replanting the ecosystem with faster growing trees species like slash and loblolly pines. With this replanting, faster tree growth and greater lumber production was achieved. [5]
