Evaluation of supply capacity of food emergency logistics in natural disaster

2016 International Conference on Logistics, Informatics and Service Sciences (LISS), 2016
In China, natural disasters which are regionalism, diversity, frequency, extensive losses greatly threaten the people's personal safety and property security. However, some circumstances could exist in affected areas, such as shortage and invalid supply of emergency food, competition for materials among people and so forth.

How does a shorter supply chain affect pricing of fresh food? Evidence from a natural experiment

Food Policy, 2015
The market for fresh food is often characterized by a large number of intermediaries delivering the product from the farmer to the retailer. The existence of these intermediaries, especially the informal ones, is often claimed to introduce market frictions that push fresh food prices up.

Upland Farming as a Method of Supplementing the Natural Waterfowl Food Supply in the Southeast

The Journal of Wildlife Management, 1952
Service has relied on upland farming to supplement waterfowl food on some of its southeastern refuges for more than a decade. This is particularly important on multiple-purpose, power and flood control reservoirs, where extreme fluctuation prevents natural food production.

Bud-Eating by Bullfinches in Relation to the Natural Food-Supply

The Journal of Applied Ecology, 1964
In primaeval Europe, the bullfinch (Pyrrhula pyrrhula) was presumably a bird of deciduous forest, feeding for most of the year on the seeds of various trees and herbaceous plants, and on the buds of trees in spring. In modern England, while its main habitat is still deciduous woodland, it also occurs in smaller numbers in cultivated habitats, such as ...

Natural Mortality and Reproduction for a Food Supply at Minimum Metabolism

The American Naturalist, 1965
The reproductive capacity of most mammals is far greater than what would be required in the absence of predators. In a litter of six or eight, the typical offspring does not survive to reproduce, and the typical result of reproduction is to provide a food supply for the rest of the ecological system rather than to maintain the species.

Maternal effects on offspring Igs and egg size in relation to natural and experimentally improved food supply

Functional Ecology, 2008
1. Maternal effects have been suggested to function as a mechanism for transgenerational plasticity, in which the environment experienced by the mother is translated into the phenotype of the offspring. In birds and other oviparous vertebrates where early development is within the egg, mothers may be able to improve the viability prospects of their ...

The natural regulation of buffalo populations in East Africa: The food supply as a regulating factor, and competition*

African Journal of Ecology, 1974
SummaryEvidence is presented to show that both the quality and quantity of food available to a buffalo population falls below the minimum maintenance requirements of that population at certain times of the year. In the Serengeti grasslands there was a shortage of the only good quality component, grass leaf, in the dry season, with the result that the ...

Natural toxicants in the food supply:In vitroinvestigation of the potential mechanism of action of the dietary flavonoid quercetin

International Journal of Food Sciences and Nutrition, 1993
Quercetin, a natural flavonoid, is a well-known genotoxin, but its carcinogenicity is unclear. The objective of these studies was to investigate and compare the effects on glycolytic flux of quercetin and the known toxic xenobiotic phorbol 12-myristate 13-acetate (PMA) in a cell culture model. Rat kidney cells (NRK-49F) grown in culture were exposed to
