This hypothesis about a common maker is further supported by observations made by MacNaughton and Pickerill (1995), who noted intergradations
between Gordia marina and the straight to sinuous burrow Planolites isp.
Quoting Sillitoe (2002) that knowledge is a continuum and at one end is the indigenous knowledge and at the other end is the scientific knowledge with many intergradations
between these two, the author stated that the issues raised by these different definitions of knowledge should be considered while introducing technology in the emerging economies.
of clay and object in a minimalist manner speak to the ambiguity that he faces in his culture, whereas Ekstam uses found objects on his large rolling landscapes to discuss his plight as a father, artist and world traveller.
The patterns of habitat intergradations are even more complex in ecotone zones of broad contact between the Pantanal and Cerrado (Lacher and Alho, 2001).
Intergradation of habitats of non-volant small mammals in the patchy Cerrado landscape.
Isolated scales derived from acid dissolution of fossiliferous rocks can often be associated with considerable assurance into suites of scales representing different parts of the body of an individual species, using the clues given by intergradations
of scale structure within the samples (e.g., Marss 1999).
Gulf of Mexico: Balech, 1967; Steidinger et al., 1967; Steidinger & Williams, 1970** (according to these authors, the intergradations
The great plasticity in the external attributes of the soldiers of the lignata species group (such as the presence / absence of ocelli and eyes, and vestigial alary sclerites) make this an ideal group for the study of the evolution of caste intergradations
; as proposed by Baroni Urbani and Passera (1996), who suggest that in some cases the soldier developed not from the worker, but from the female (see Ward 1997 for a reply).
The local occurrence of such semidesert areas means that all intergradations
between humid and dry climate are present at close distance and at various elevations.
exist between oligolecty and polylecty (Michener 1979, Moldenke 1979a, Westrich 1989, Wcislo and Cane 1996).
between all these forms occur even within individual trackways, and thus we think that brontozoid tracks have not yet been found in the Red Head Member and that there is no evidence of coelophysoid theropods in this unit.
