During the next two weeks, floral-color change could be investigated in Aster divaricatus or A. prenanthoides, both of which grow on my property. You could investigate one or more of the above hypotheses relative to the situation in Aster. For example, you could investigate whether the presence of color-changed flowers enhances the plant as a visual target for pollinators as well as determine w...

Land surface temperature (LST) is an important parameter that is highly responsive to surface energy fluxes and has become valuable to many disciplines. However, it is difficult to acquire satellite LSTs with both high spatial and temporal resolutions due to tradeoffs between them. Thus, various algorithms/models have been developed to enhance the spatial or the temporal resolution of thermal i...

Recent development of the user-friendly software package “Co-registration of Optically Sensed Images and Correlation” (COSI-Corr), which allows for automatic and precise ortho-rectification, co-registration, and sub-pixel correlation of pushbroom satellite and aerial images, has enabled Earth’s surface dynamics to be accurately monitored using optical imagery [1]. This technique compares two im...

The forest temperature is one key parameter in the models developed for providing early fire risk alerts. The satellite remote sensing data are the best way to obtain this parameter both regionally and globally. This study proposes an approach to obtain Forest Surface Temperature (FST) by means of Terra-ASTER (Advanced Spaceborne Thermal Emission and Reflectance Radiometer) multiband algorithms...

Eggs of the sea urchin Strongylocentrotus purpuratus were examined by indirect immunofluorescence microscopy for tubulin-containing structures at intervals from fertilization through first cleavage. The staining revealed that the monaster is made up not only of the sperm aster but also of tubulin-staining fibers originating elsewhere in the egg. The monaster does not divide directly but is brok...

This paper evaluates the suitability of readily available elevation data derived from recent sensors – the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and the Shuttle Radar Topography Mission (SRTM) – for glaciological applications. The study area is Nevado Coropuna (6426 m), situated in Cordillera Ampato of Southern Peru. The glaciated area was 82.6 km in 1962, based...
