GENETIC DIVERSITY AMONG SWEET POTATO CROPS CULTIVATED BY TRADITIONAL FARMERS
(Univ Fed Rural Semi-arido-ufersa, 2018-07-01)
The genetic variability within the crop species Ipomoea batatas is broad, hence, in order to support future breeding programs it is of the utmost importance that germplasm banks be created, conserved, and characterized. ...
Color fractal descriptors for adaxial epidermis texture classification
The leaves are an important plant organ and source of information for the traditional plant taxonomy. This study proposes a plant classification approach using the adaxial epidermis tissue, a specific cell layer that covers ...

A SIMPLE METHOD FOR DETERMINING LOCATION OF FORAGING ANT NESTS USING LEAF-CUTTING ANTS AS A MODEL
(Blackwell Wissenschafts Verlag Gmbh, 1993-11-01)
In many situations, it is difficult to evaluate the location of nests of ants, especially in tropical systems, or to determine which trail system corresponds with which nest, as in the case of high-density populations of ...
Comparison of radial growth rate of the mutualistic fungus of Atta sexdens rubropilosa forel in two culture media
(Sociedade Brasileira de Microbiologia, 2010)
In vitro culture of the mutualistic fungus of leaf-cutting ants is troublesome due to its low growth rate, which leads to storage problems and contaminants accumulation. This paper aims at comparing the radial growth rate ...
