Web8 de jan. de 2024 · Lianas are woody vines that play an important role in forest dynamics in tropical and subtropical areas. Their relationship to various biotic and abiotic conditions is, however, not yet wholly clear. We explored how the size, climbing mechanisms, diversity and abundance of woody lianas is related to host plant size, environmental factors and … WebIn the simplest case, consider a camera grid defined by the four corner cameras as X km by X km or X 2 km 2. The effective area is defined as. A (W) = {X^2} + 4XW + \pi {W^2}. (6.13) Note that 4 X is simply the perimeter of the grid. To estimate density we use the estimate \hat N and fix X, W is unknown.
