местообитание

habitat, site

Six heathland sites were used in the present study. These included samples of all types of habitats occupied by wheatears (каменки, Aves), ranging from bare sand, through extremely short-cropped turf, to longer grass, sand sedge (Carex sp.) and heather (Calluna vulgaris) .

There is a marked preference for nesting in abandoned caves, if available, and the highest breeding density are reached in areas with abundant caves. These caves offer constant moderate temperatures in aqenvironment characterized by thermal extremes .

The boulder-fields are the preferred habitat of this bird species, which occurs only rarely above the Cave Sandstone belt .

Birds are found from near sea-level to 1 500 m elevation, locally to 2 200 m. They are quite flexible in their habitat requirements. .

Therefore, these birds avoid barren areas and, conversely, are locally quite common in cultivated valleys of the Elburz Range .

гетерогенности местообитание степень - extent of habitat heterogeneity

качество местообитание - habitat quality

конкуренция межвидовая из-за местообитание - interspecific competition for habitat

маргинальный местообитание - marginal habitat

насыщенное местообитание - saturated habitat

оптимальное местообитание - optimal habitat

перекрывание местообитание - у разных видов

symbiotopy, partial symbiotopy

субоптимальное местообитание - subortimal habitat

местообитаний выбор - habitat selection

межвидовые различия в местообитание - interspecific differences in habitat selection

местообитаний разрушение - habitat loss, habitat destruction

Human-associated habitat loss is a threat to species .

Habitat is destroyed due to human destructive activities .

Habitat loss does not immediately threaten an individual life, but its cessation does not allow a species until habitat is replaced. Speсies decline may occur with no habitat loss .
