Over the past decade, theory and observations have suggested intraspecific variation, trait-based differences within species, as a buffer against biodiversity loss from multiple environmental changes. This buffering effect can only occur when different p
In the present sample, either of the first two conditions could occur without causing more ASYMMETRICAL FOWLS 225 bias than there is in the non-silver group at hatching, but in the third case a contrary, compensatory ratio in the remainder of the red, yellow-legged birds would be necessary ...
In Spinacia oleracea, where divisions occur throughout the growth of the root and are found in both primary and secondary roots, these polyploid cells did not arise during embryogenesis but during germination and during continued growth. The origin of polyploid cells in Anchusa capensis at the ...
of whichS. albumis the only species found on the Asian mainland, whileS. yasiis native to the islands of Fiji and Tonga7. However, where these species are grown together in plantations, hybridization is known to occur with subsequent changes in metabolic profiles among hybrids8. The quality ...
In the absence of both Notch and Numb, however, the two daughter cells adopt the RP2 fate indicating that Numb is necessary to specify an RP2 fate only when there is an intact N-signaling; Numb, thus, blocks Notch-signaling from specifying a sib fate to a cell. In the CNS, while ...
The top three groups of each division of these two transcriptomes were the same. Specifically, the top three groups in ‘Biological process’ were ‘cellular process’, ‘metabolic process’ and ‘biological regulation’; the top three groups in ‘Cellular component’ were ‘cell’, ‘cell part...

of the considerable variability in biochemical composition and the physical properties of the algae cell wall. Conventional physical extraction processes, such as extrusion, do not work well with algae given the thickness of the cell wall and the small size (about 2 to about 20 nm) of algal ...
In reciprocal crosses, on the other hand, cell formation does not occur, but mitotic irregularities eventually lead to the complete disintegration of the endosperm. In the latter case none of the seeds is viable, but in the former some of the caryopses may germinate, depending upon the ...
(or embryo development) is the development of a fertilized egg that fuses with a sperm, forming a zygote. After zygote stage, many changes occur and the embryo undergoes several mitotic divisions to generate tissues layers that eventually develop into specific organs6,7. During oogenesis, ...
