2007. Phyto- plankton diversity (alpha, beta, and gamma) from the Araguaia River tropical floodplain lakes (central Brazil). Hydrobiologia 557: 455-461.Nabout, J. C., Nogueira, I. S., Oliveira, L. G., and Morais, R. R. (2007). Phytoplankton diversity (alpha, beta, and gamma) ...
The latitudinal distribution patterns of alpha, beta and gamma diversity of reptiles, amphibians and herpetofauna were analyzed using individual binary models of potential distribution for 301 species predicted by ecological modelling for a grid of 9,932 quadrants of ~25 km2 each. We arranged ...
Alpha, beta, and gamma also played major roles in the loss of diversity: the end- Ordovician mass extinction (possibly the second greatest mass extinction) did not just reduce alpha diversity, but it also left an early Silurian world with low beta and gamma diversity.“Alpha, Beta, or ...
Species diversity may be additively partitioned within and among samples (alpha and beta diversity) from hierarchically scaled studies to assess the proportion of the total diversity (gamma) found in different habitats, landscapes, or regions. We developed a statistical approach for testing null hypoth...
WHERE DOES ALL THE DIVERSITY GO AGAIN? A CENOZOIC PERSPECTIVE ON VARIATIONS IN ALPHA, BETA AND GAMMA DIVERSITY IN SHALLOW MARINE ENVIRONMENTSFluctuations in regional endemism and biogeographic similarity between regions appear related to the opening and closing of major oceanic gateways. Nevertheless some...
Assessment of biodiversity in a changing world is a key issue and studies on the processes and factors influencing its history at relevant time scales are needed. In this study, we analyzed temporal trends of plant diversity using fossil pollen records f
Alpha (α) keratins are found in all vertebrates, while beta (β) keratins are found exclusively in reptiles and birds. We have studied the molecular evolution of these gene families in the genomes of 48 phylogenetically diverse birds and their expression in the scales and feathers of the ...
N-glycosylation profiles of five 2-proline-stabilized (2P), recombinant ectodomain S proteins including Alpha, Beta, Gamma, and Delta variants along with S—D614G as a control were characterized by liquid chromatography-tandem mass spectrometry (LC–MS/MS). To provide the best possible variant-...
alpha-HPV; beta-HPV; E6 oncoprotein; cervical cancer; HNSCC; cSCC 1. Introduction Human papillomaviruses (HPVs) are a family of small DNA viruses that infect epithelial cells at various anatomical sites of the human body. It is a large and diverse group of viruses, divided into five genera...
and gamma diversity. Unlike many other studies, the high beta diversity mainly consists of the richness difference rather than species replacement. The high overall beta diversity showed low similarity between the habitats, while high overall alpha diversity exposed high species diversity at the local ...
