As people encroach increasingly on natural areas, one question is how this affects avian biodiversity.
The answer to this is partly scale-dependent. At broad scales, human populations and biodiversity
concentrate in the same areas and are positively associated, but at local scales people and biodiversity are
negatively associated with biodiversity....

As people encroach increasingly on natural areas, one question is how this affects avian biodiversity. The answer to this is partly scale-dependent. At broad scales, human populations and biodiversity concentrate in the same areas and are positively associated, but at local scales people and biodiversity are negatively associated with biodiversity....
Mutualistic associations between cnidarians, such as corals, and photosynthetic
dinoflagellate algae provide the trophic and structural foundation of coral reef
ecosystems. In many cases, this intracellular mutualism is highly specific and must be
established anew for each generation of host corals. The ability to maintain partner
specificity across generations implies...
Many devices and methods for radiological searches are currently being developed, including scanning using simple detectors, mapping using large-volume detectors, and Compton imaging using 3-D position sensitive detectors. However, these devices are typically expensive and the methods used require long periods of time to generate a direction or location. The...
Using a spectrometer and photomultiplier tube, I measured the electromagnetic radiation transmittance properties of three types of tissue-- ventral skin, cardiac muscle, and liver tissue--in the red-sided garter snake Thamnophis sirtalis parietalis between the wavelengths of 450 and 850 nanometers (nm). Control readings were taken using a 10⁻² neutral density...
