In this article it is claimed that in order to obtain the right composition, structure, and functionality for a new product, one needs to anticipate what the demand of the product will be and take into account all costs involved (associated manufacturing and supply chain). To obtain the demand, one needs a pricing model, which in turn relies on consumer preferences that are connected to the pro...
Geographic variability in abundance can be driven by multiple physical and biological factors operating at multiple scales. To understand the determinants of larval trematode prevalence within populations of the marine snail host Littorina littorea, we quantified many physical and biological variables at 28 New England intertidal sites. A hierarchical, mixed-effects model identified the abundan...
The traditional use of insects as food continues to be widespread in tropical and subtropical countries and to provide significant nutritional, economic and ecological benefits for rural communities. Westerners should become more aware of the fact that their bias against insects as food has an adverse impact, resulting in a gradual reduction in the use of insects without replacement of lost nut...
