Paleontologists working in Tanzania have identified a new species of hyaenodont, a type of extinct meat-eating mammal. The study is published today, National Fossil Day, in the journal PLOS ONE and fu...
Paleontologists have identified a new species of titanosaurian dinosaur. The research is reported in a paper published this week in the Journal of Vertebrate Paleontology and is funded by the National...
Understanding the effects of land-use change on zoonotic disease risk is a pressing global health concern. Here, we compare prevalence of Yersinia pestis, the etiologic agent of plague, in rodents ac...
For video b-roll associated with this discovery, please contact Dena Headlee at dheadlee@nsf.gov.Palontologists have identified a new species of titanosaurian, a member of the large-bodied sauropods t...
Climate change has profound implications for managing freshwater resources and species dependent on those resources. Water is an essential component of the life support system of the earth, and a basi...
A conceptual model of the effects of rainfall variability on groundwater recharge was developed and applied to a small forested catchment in semi-arid Tanzania. The model simulated dual-domain recha...
This study examines the effect of changes in land use and vegetation cover on water yield from the Ruhudji catchment in southern Njombe. An evaluation was also made to assess the effect of afforestrat...
We sampled a tidal creek (Ras Dege, Tanzania) during a 24-h cycle to document the variations in a suite of creek water column characteristics and to determine the relative influence of tidal and biolo...
The Sinya Beds of the Amboseli Basin in Tanzania and Kenya consist largely of carbonate rocks and Mg-rich clays that are intensely deformed where exposed in and near former meerschaum mines. The carbo...
Low-angle X-ray powder diffraction (XRD) measurements of soil samples, made at controlled relative humidities, showed the presence of major reflections at 20–33, 10–27, and 7–8 Å. The first refl...
The catalytic activity of sepiolite from Amboseli, Tanzania, for the dehydration and dehydrogenation of ethanol at 150°–300°C has been studied using a flow reactor. Both reactions occur, but the catal...
