Thus, instead of making robust generalizations about habitat fragmentation (such as "patchiness is stabilizing") we should seek predictions that are based on the details of an organism's dispersal behaviour and demography... P Kareiva - 《Nature》 被引量: 1100发表: 0年 When does fragmentation...
That's what most people think of. But for biologists, the concept of a niche also includes the way an organism functions in its habitat, how it interacts with other plant and animal species, with the soil, the air, the water and so on. Okay. Now let's put it all together. If you...
Professor: Okay. That's what most people think of. But for biologists, the concept of a niche also includes the way an organism functions in its habitat, how it interacts with other plant and animal species, with the soil, the air, the water and so on. ...
Dormancy is the ability of an organism to arrest growth, development, and reproduction temporarily1. Dormancy includes hibernation and torpor in mammals and birds2, embryonic developmental arrest in mammals, birds, reptiles, bony fish, and elasmobranchs3,4,5,6,7,8,9,10, as well as developmental...
If stressful conditions are localised or remain only for a short duration an organism either migrates or suspends itself B Mammals from colder climates have shorter ears and limbs to minimise heat loss C An organism can move form a stressful habitat to a more hospitable area and return when th...

2. Habitat of Actinobacteria 2.1. Terrestrial environment Soil remains the most important habitat for Actinobacteria with streptomycetes existing as a major component of its population. According to numerous reports, Streptomyces was encountered to be the most abundant genus isolated in each of the study...

cortex without a wide range of emotions would simply be an empty warehouse consuming a significant proportion of the protein and calories needed by an organism, thus decreasing fitness. Thus, a larger neo-cortex was dependent upon a prior enlargement of sub-cortical areas of the brain where ...
In P. monodon, the organism has been implicated as a cause of red disease in India (Jayasree et al., 2006). Pathogenicity has been established in tiger prawns with the LD50 dose of 1 × 105 CFU (colony forming units) shrimp−1 (Sudheesh and Xu, 2001). The corresponding value in ...
