opportunistic species การใช้

• Although, as an opportunistic species, it can tolerate some disturbance, continued trampling along forest trails due to recreation poses a threat.
• Hairy milkweed can be an aggressive, opportunistic species, capable of overtaking a suitable sprouting location and killing the plants it grows upon.
• Its role as a species of mature forests has led it to be replaced by more opportunistic species in areas where forests are cut over.
• It is an opportunistic species tolerant of stressful conditions, and often found in polluted waters ( sewer discharges, hydrocarbons, metals . . . ) where it out-competes less tolerant species.
• One factor was product of aridification, other groups responded to favorable climatic periods and expanded across the available habitat, occurring as opportunistic species across wide distribution; other groups diverged over long periods within isolated areas.
• With a great capacity for adaptation, Ivy will grow wherever development conditions and habitat similar to that of its European origins exist, occurring as opportunistic species across a wide distribution with close vicariant relatives and few species, indicating recent speciation.
• For example, species diversity almost necessarily increases during early succession as new species arrive, but may decline in later succession as competition eliminates opportunistic species and leads to trophic properties all show variable patterns over succession, depending on the particular system and site.
• Several ecological guilds exist, including abundant host-specific and host-generalist species ( 1 ), low background and potentially opportunistic species ( 2 ), and non-symbiotic species closely associated with the coral s biome ( 3 ) and / or occupying unrelated habitats ( 4)
• Even comparatively simple creatures like fish and rodents are surprisingly plastic in their responses to the world, following a different script depending on the chances and the circumstances in which they find themselves _ and humans, being the most plastic and opportunistic species of all, surely have the highest stack of screenplays from which to choose.
• Although the majority of the species are the products of parapatric speciation, some groups have an ancient Gondwanan distribution and some groups responded to favourable climatic periods as opportunistic species and expanded across the available habitat, these last groups occur across wide distribution with close relatives and few species, indicating the recent divergence of these species.
