- adj. pertaining to altitude
A second kind of altitudinal corridor would be for planes to fly above other traffic but use, as a main means of avoiding collision, a technique called "see and avoid," which requires pilots to basically look out their windows to detect other aircraft.
For example, they do not allow for altitudinal movement of species.
Like most protected areas in Mesoamerica, the montane parks of the Talamancan forests lack full edological connectivity and regulatory oversight, and do not represent the gamut of ecosystems needed to support altitudinal migrants.
For example, my students (both grad and undergrad) and I have recently undertaken a new project in a Puerto Rican rain forest using professional free climbing equipment and a LiCor CO2 meter to measure photosynthesis and respiration of the forest at 100 meter altitudinal levels from the bottom to the top of the Luquillo Mountains.
The Caribbean slope is a major migration route; neotropical and altitudinal migrants comprise about 30% of the avifauna, particularly against the foothills.
Crop damage by the macaque is widespread; patterns of crop damage are similar across altitudinal zones and do not seem to be correlated with macaque density.
The altitudinal range of this natural region has a lower limit below the level of the Andean forest and an upper limit below the permanent snow cap.
To seasonal changes are added two climatic gradients: altitudinal and along its length, also rain-shadowing, marked diurnal variations in temperature and a persistent daily belt of cloud above ~950 m.
As a result of the altitudinal variation, the ecoregion consists of various microclimates that create a mosaic of vegetation in the mountainous area.
The altitudinal gradient, from the upper peaks of the Paramillo, at 3.960 meters (m) above sea level (masl.) to the low alluvial valley at 200 masl. and to the mangroves at sea level, makes it possible for the region to have several types of ecosystems and forests in within a relatively small area.
