Assisted migration generally involves translocating species beyond their existing or former range, to a contiguous environment where barriers to dispersal have occurred through habitat fragmentation, or to an adjacent environment with different temperature regimes [5], [6], [7].
In a similar fashion, Konopka (2009) defines communities as 'multispecies assemblages, in which organisms live together in a contiguous environment and interact with each other'.
Being contiguous with the environment, mucosal surfaces are constantly exposed to toxic and pathogenic insults [1], [2].
In other words the one-link nodes are the input terminal of the system and are connected with the output terminal of contiguous systems (female environment, seminal fluid, artificial media in laboratory technologies,...)...
Since the canal system is contiguous with the external environment, resistance to ion passage occurred through two simple cell layers, the endopinacoderm and basopinacoderm (Figure 1A inset).
A comparison of the completely sequenced genome of an H aloquadratum walsbyi isolate (DSM 16790) with an environmental metagenome, both sampled from the same solar saltern in Spain, showed multiple chromosomal regions to be underrepresented in the environment, whereas contiguous regions of environmental fragments only partially matched regions of the sequenced genome.
A large number of issues have to be considered, such as the spectrum sharing policy, operators' individual traffic demands, structure of the shared spectrum, i.e., contiguous/non-contiguous, the operating environment, channel propagation characteristics, and inter-operator interference.
Southern California environments lack the contiguous canopy found in the eastern deciduous forest, and Culex mosquitoes feed readily at ground level (41, 42).
Generally, the diversity subcarrier permutation performs well in a high speed mobile environment while the contiguous subcarrier permutation is suitable for fixed or low speed applications.
Great differences occur among their physicochemical processes, including biogeochemical pathways, the relative ecological importance of the floodplain (if present), the main stem of the river or stream, the hyporheic zone (the environment below the bed), and contiguous terrestrial areas.
