There is immense variation in the types of Texas soil. ThePiney Woods region of East Texas has a gray and tan topsoil that covers the red subsoil usually within about 2 feet (0.6 metre) of the surface. The soil along the upper and middle Texas coast is black clay or loam, with lighte...
Much of India’s territory lies within a large peninsula, surrounded by theArabian Seato the west and theBay of Bengalto the east;Cape Comorin(Kanniyakumari), the southernmost point of the Indian mainland, marks the dividing line between those two bodies of water. India has twounion territor...
Our approach assumes that the population density of Middle Pleistocene hominins may be inferred from ethnographic hunter-gatherer population densities. This assumption may be negatively affected by the biological, cultural and technological differences that exist between the recent hunter-gatherer populations ...
Population density is the mean population density for each sub-region in 2000. Full size image This bioclimatic gradient in change intensities is paralleled by a similar gradient in population pressures, with lowest average population densities (2.6 persons per km2) occurring in the Saharan sub-...
Population genetic studies of symbiotic anthozoans have been historically challenging because their endosymbioses with dinoflagellates have impeded marker development. Genomic approaches like reduced representation sequencing alleviate marker development
Bindler G, Plieske J, Bakaher N, Gunduz I, Ivanov N, van der Hoeven R, Ganal M, Donini P: A high density genetic map of tobacco (Nicotiana tabacum L.) obtained from large scale microsatellite marker development. Theor Appl Genet. 2011, 123: 219-230. 10.1007/s00122-011-1578-8. ...
Furthermore, this study investigated the relationships among land cover change (LCC), population growth (PG), road density (RD), and relative change of flooding (RCF) areas for the period between 2000 and 2017. The results showed that areas with very high susceptibility to flooding increased ...
In China, for example, the migration of people from the West to the East sheds some light on why population in 42% of Chinese FUAs declined in the considered period. Measuring population dynamics using FUAs rather than just high-density urban centres proofs particularly useful to distinguish ...
This raises the questions of the true abundance of massive galaxies and the star-formation-rate density in the early Universe. Although several massive galaxies that are invisible in the ultraviolet have recently been confirmed at early epochs2,3,4, most of them are extreme starburst galaxies ...
Flooding affects more people than any other environmental hazard and hinders sustainable development1,2. Investing in flood adaptation strategies may reduce the loss of life and livelihood caused by floods3. Where and how floods occur and who is exposed
