There are aquatic and terrestrial ecosystems, and within both are living (biotic) and nonliving (abiotic) factors. The goal of this activity is for students to identify biotic and abiotic factors in different ecosystems. Students will discover how these different factors interact and impact an ...
These observations suggest that biological activity and degradation of organic matter may play a fundamental role in the travertine formation. We conclude that the individual fabric types reflect the precipitation processes due to interplay between abiotic and biotic and/or a combination of both ...

taeniata testosterone levels are not altered following a short-term exposure to conspecific biotic and to abiotic sounds. Our results are suggestive of a threshold influence of testosterone on the vocal activity of the species studied. Further explorations of the influence of abiotic sounds on ...

DefinitionAbiotic refers to the physical and chemical processes that take place in natural environments but are driven by mechanisms that do not involve any biological activity. Although major physical and chemical cycles on Earth can hardly escape the activity of the biosphere, some processes do not...
on each test day, as the locomotor activity in Drosophila exhibits a distinct circadian rhythm65. An increased negative geotaxis behaviour, i.e. the flies crawled higher, was interpreted as beneficial, because the ability to escape a potential stressful environment is of key importance for fitness...
Environmental stresses play crucial roles in the productivity, survival and reproductive biology of plants as well as crops. Plants are subjected to many forms of environmental stress, which can be included into two broad areas: abiotic (physical environment) and biotic (e.g. pathogen, herbivore)...
26. Biotic interactions, such as pre-dispersal predation, may further constrain seed productivity at treeline27, impacting future treeline range expansion. Successful recruitment also depends on the availability of suitable microsites that provide the necessary conditions for emergence and establishment of ...
