The behavior of target animals is pivotal in designing the size, shape, location, and habitat of these reserves. For example, many bird reserves in Central and South America are located in high mountains, but in one instance 25% of the local birds left the protected area to forage . [ 16 ]
The balance of nature, also known as ecological balance, is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system.
The leaves provide energy and nutrients for the trees, which provide homes and food for the forest. Through satellite data, the radiation use efficiency (RUE) calculates the annual amount of photosynthesis that occurs in temperate rainforests. A diverse amount of photosynthesis occurs based on the location and microclimates of the forest.
[22] [23] [24] Some sources however say even at least 50 inches of precipitation annually qualifies an area as being a rainforest. [25] On the other hand, in the book ‘Temperate and Boreal Rainforests of the World’ by David Suzuki says a temperate rainforest is defined by least 1,200 mm (47.24 inches) of average annual precipitation.

Extent of temperate broadleaf and mixed forests An example of temperate broadleaf and mixed forest in La Mauricie National Park, Quebec.. Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions.
Take, for example, the mirror-mark test, which scientists sometimes use to see if an animal recognizes itself. In a series of studies, the cleaner wrasse fish seemed to pass the test .
Temperate deciduous forests are characterized by a variety of temperate deciduous tree species that vary based on region. [6] Most tree species present in temperate deciduous forests are broadleaf trees that lose their leaves in the fall, [8] though some coniferous trees such as pines (Pinus) are present in northern temperate deciduous forests.
