Abstract Across the tropics, millions of rural families rely on non-timber forest products for protein, subsistence, and other financial or cultural uses. Often, communities exploit biotically dispersed trees their mammalian avian seed disperser. Empirical findings have indicated that many plant animal resources are overexploited, presenting challenges biodiversity conservation sustainable live...

Intra- and interspecific spatially contagious seed dispersal has far-reaching implications for plant recruitment, distribution, and community assemblage. However, logistical and analytical limitations have curtailed our understanding concerning the mechanisms and resulting spatial patterns of contagious seed dispersal in most systems and, especially, in complex seed-disperser networks. We inves...

We demonstrate programmable spectral shaping with simultaneous broad-bandwidth(>40nm) and high-resolution(<4GHz) using a 2-D VIPA-Grating pulse-shaper with a LCOS SLM. The apparatus is capable of scaling to bandwidths of 100s of nm with sub-GHz resolution. © Optical Society of America OCIS codes: (320.5540) Pulse Shaping; (320.7085) Ultrafast information processing Femtosecond pulse shaping is ...

We present a single disperser spectral imager that exploits recent theoretical work in the area of compressed sensing to achieve snapshot spectral imaging. An experimental prototype is used to capture the spatiospectral information of a scene that consists of two balls illuminated by different light sources. An iterative algorithm is used to reconstruct the data cube. The average spectral resol...

This paper describes a single-shot spectral imaging approach based on the concept of compressive sensing. The primary features of the system design are two dispersive elements, arranged in opposition and surrounding a binary-valued aperture code. In contrast to thin-film approaches to spectral filtering, this structure results in easily-controllable, spatially-varying, spectral filter functions...
