The understory is the underlying layer of vegetation in a forest or wooded area, especially the trees and shrubs growing between the forest canopy and the forest floor. Plants in the understory comprise an assortment of seedlings and saplings of canopy trees together with specialist understory shrubs and herbs.
The Project is located near Manaus. The Biological Dynamics of Forest Fragments Project (BDFFP; or Projeto Dinâmica Biológica de Fragmentos Florestais, PDBFF, in Portuguese) is a large-scale ecological experiment looking at the effects of habitat fragmentation on tropical rainforest.
The understory or understorey layer lies between the canopy and the forest floor. It is home to a number of birds, snakes and lizards, as well as predators such as jaguars, boa constrictors and leopards. The leaves are much larger at this level and insect life is abundant. Many seedlings that will grow to the canopy level are present in the ...
The understory layer lies between the canopy and the forest floor. The understory is home to a number of birds, small mammals, insects, reptiles, and predators. Examples include leopard (Panthera pardus), poison dart frogs (Dendrobates sp.), ring-tailed coati (Nasua nasua), boa constrictor (Boa constrictor), and many species of Coleoptera. [5]
[1] [2] [3] In forest ecology, the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, arboreal animals, etc.). [4] The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience , and functioning. [ 5 ]
Through the formation of different layers a given habitat is better utilized. Strongly vertically stratified habitats are very stable ecosystems. The opposite is not true, because several less stratified vegetation types, such as reed beds, can be very stable. The layers of a habitat are closely interrelated and at least partly interdependent.
An average understory height of 5.0–6.5 feet (1.5–2.0 metres) was preferred by brush mice over lower understory cover. [14] In another study, brush mouse presence was positively correlated with microhabitats of shrub cover up to 10 feet (3.0 m) tall, logs over 3 inches (7.6 cm) in diameter, and understory trees 10–33 feet (3.0–10.1 ...
In North America, other species found in this forest understory habitat include leatherleaf (Chamaedaphne calyculata), bog rosemary (Andromeda glaucophylla), bog laurel (Kalmia polifolia), pitcher plant (Sarracenia purpurea), Labrador tea (Rhododendron groenlandicum), cloudberry (Rubus chamaemorus), rhodora (Rhododendron canadense), glossy ...
