Biotic interactions in Antarctic terrestrial ecosystems: Are they a factor?

Soil Biology and Biochemistry, 2006
Antarctic terrestrial ecosystems are noted for their relative simplicity and limited trophic structure. In this context, knowledge of biotic interactions in structuring terrestrial soil communities would seem beneficial from a theoretical perspective as well as from a conservation perspective.

Modelling the influence of biotic factors on species distribution patterns

Ecological Modelling, 2016
Biotic interactions can have large effects on species distributions yet their role in shaping species ranges is seldom explored due to historical difficulties in incorporating biotic factors into models without a priori knowledge on interspecific ...

Biotic Stress to Legumes: Fungal Diseases as Major Biotic Stress Factor

2021
Legumes represent one of the most valuable crops all over the world because of their high content of protein, carbohydrates, fibers and minerals. Legumes significantly affect animal and human health along with soil fertility enhancement. Despite large areas under legume cultivation, the per year legume produces are insufficient due to crop losses ...

Fire and Biotic Factors Afecting Germination

Ecology, 1952
Most plant communities are so complex that a clear-cut analysis of the relative importance of these 7 mechanisms is either very difficult or impossible. By working with simplified systems or with natural conditions where already a number of these mechanisms are excluded or inoperative, the significance of the other mechanisms can be assessed.

Biotic and Abiotic Factors Affecting Microplastic Degradation and Deposition

Marine Environmental Research
Although microplastics are ubiquitous in marine systems, our current knowledge on how biofilms that form on them affect their degradation and removal from the surface ocean is limited. In the ocean, it is expected that plastics denser than seawater will sink (i.e., polyvinyl chloride or polyethylene terephthalate), but in the water column their fate ...

Biotic Factors in the Alpine Zone

1967
Animals as well as plants are subjected to the peculiarities of a high altitude climate on Mount Kenya, just as they are on all the other tropical mountains of the world. However, unlike the plants, they are able to remain in a niche wherein they are protected from the environmental extremes to which the vegetation is exposed.

An Exceptionally Powerful Biotic Factor

1993
The questions raised by the relationship between humans and their physical environment are as old as western thought. As Glacken (1967) has pointed out, people throughout the ages have persistently asked three broad questions: 1) Is the Earth a purposely made creation, or, put another way, is it a divinely designed Earth for humans? 2)

Control of Weeds and Other Biotic Factors

2016
Weeds are plants whose presence is undesirable at a time and/or place because they compete with crops for resources, deteriorate the quality of the harvested product and can hinder harvesting. The most important weed species include C4 perennials with vegetative propagation.

Control ofCryptococcus neoformansin nature by biotic factors

Medical Mycology, 1982
Two bacterial species (Pseudomonas aeruginosa and Bacillus subtilis) isolated from pigeon droppings, displayed anti Cryptococcus neoformans activity on 4 of 6 media and sterilized pigeon droppings. Acanthamoeba palestinensis trophozoites isolated from pigeon droppings ingested and killed 99.9% of C neoformans cells after 7 days of incubation. Mites and
