Botrytis cinerea (B. cinerea) Pers. Fr. [teleomorph Botryo t in ia fucke l iana (de Bary ) Whetze l ] i s a phytopathogenic fungi responsible for grey mould, which is an important disease in more than 200 species of fruits, vegetables, ornamental crops and affecting a great number of organs[1]. Grey mould, cause important economic losses before and after the harvest[2], worldwide losses from th...

Volatile compounds in Fuji apples harvested at two different maturities were measured at harvest and after 5 and 7 months of cold storage (1 degrees C) in four different atmospheres. When the samples were characterized by both chromatographic measurements of volatiles and responses of an electronic nose, the analyses showed a clear separation between fruits from different storage conditions (a ...

The mean numbers of colony-forming units of molds present on vegetables at the time of harvest were in the range of 4.2 X 10(3) to 6.7 X 10(3)/g for all vegetables except cucurbits and asparagus. The numbers were not influenced by cultivars within species, duration of the growing season, distant separation of the growing fields, or elevation above ground. Numbers increased with rainfall during ...

Forest harvest alters natural nutrient cycles, which is reflected in stream water run-off from harvested catchments. Nitrate is an essential nutrient for plant growth, but increased concentrations in rivers, lakes, and oceans have contributed to eutrophication and anoxic conditions. Based on a literature review, we assessed the impact of three different harvest methods—clearcut, patchcut, and s...

Recruitment in cooperative breeders can be negatively affected by changes in group size and composition. The majority of cooperative breeding studies have not evaluated human harvest; therefore, the effects of recurring annual harvest and group characteristics on survival of young are poorly understood. We evaluated how harvest and groups affect pup survival using genetic sampling and pedigrees...

Change in the size of populations over space and time is, arguably, the motivation for much of pure and applied ecological research. The fundamental model for the dynamics of any population is straightforward: the net change in the abundance is the simple difference between the number of individuals entering the population and the number leaving the population, either or both of which may chang...
