Understanding the abiotic and biotic factors associated with this ecotonal process will enable more accurate predictions about the response of high-altitude forests to climate change.
In the ecotonal area there was no significant difference in the numbers of N.

These programs specifically target the ecotonal habitat that developed ubiquitously in Europe when cultivating marginal land was considered too labor-intensive and costly.
This area is an ecotonal zone at the junction of three major ecogeographic regions of Texas: the Edwards Plateau, the Llano Estacado and the Trans-Pecos (Blair 1950).
Ecotonal areas (interface areas between forests and fields) are excellent habitats for hard ticks.
In northeastern Arkansas, the general rarity and sparse distribution of the silver redhorse combine to only hint at an analogous propensity to occupy ecotonal riverine habitats.
Poneromorphs were encountered in a great diversity of vegetational associations (Table 2) including tropical deciduous forest (TDF), ecotonal areas between TDF and pine-oak forests, thorn forests, pastureland, urban and suburban vegetation, and a variety of agroecosystems (including mango, avocado, and guava orchards).

The site occupies an ecotonal boundary dividing the semiarid desert steppe, associated with the Yellow River and foothills of the Helan Mountains, from the significantly more arid Ordos Desert.
