Furthermore, the occurrence of 'escaped' vertical stems only on the extreme downwind edge of larger krummholz mats is dynamically similar to the ultimate transformation of stunted/disfigured growth forms of ecotonal
trees to the forest-tree habit characteristic of the intact subalpine forest.
areas (interface areas between major habitat types) are excellent habitats for hard ticks.
Although the records are somewhat scattered, most localities embrace an ample arc that roughly corresponds to an ecotonal
area between Monte and Chaco+Espinal (Acosta 1996).
minimus predominately occupies the sagebrush scrub, with both species being abundant in an intermediate ecotonal
area containing a relatively even mixture of conifers and sagebrush.
Third, human plague cases in the southwestern United States are closely associated with ecotonal
pinon-juniper habitat and elevation (9).
Wadi Hammeh 27 is situated in an ecotonal
setting between Irano-Turanian steppic lowlands and Mediterranean highlands, at an altitude of 83.
This species inhabits thornforest, tropical deciduous forest, and the ecotonal
belt between tropical deciduous forest and pine-oak forest (Campbell & Lamar 2004).
The aims of this paper are to survey the insects infecting fruits of 2 species of Psittacanthus (Loranthaceae) in the Cerrado-Pantanal ecotonal
area of Southwestern Brazil, also to record which species of host trees or shrubs the mistletoe was parasitizing.
The site today is ecotonal
between Lower and upper Sonoran life zones.
Small rodents were live-trapped in deciduous mixed forest and ecotonal
areas in Lithuania and Norway from June till October 2005-2007.
Conservation of cerrado enclaves offer the rare opportunity to combine preservation of sharp ecotonal
zones with high inter-habitat diversity in Amazonia with establishment of a complementary network of conservation units directed at preserving the cerrado biome throughout South America.
The weakness of Lower Palaeolithic settlement in broken upland regions appears puzzling since these environments in the Holocene are associated with altitudinally-zoned vegetation patches and the close spatial packing of ecotonal
