African mammals, foodwebs, and coexistence.
In the 65 million years since a mass extinction led to the demise of dinosaurs, evolution has generated amazingly diverse and complex foodwebs on each continent (1). These foodwebs contain hundreds to thousands of interacting species, each linked to other species either by feeding on them or by being fed on by them. However, it has been difficult to determine consumer diets across seasons, indi...
متن کاملFossil mammals and paleoenvironments in the Omo-Turkana Basin.
Although best known for its fossil hominins, the Omo-Turkana Basin of Kenya and Ethiopia is the source of one of the best records of vertebrate evolution from the Late Cenozoic of Africa. Located near the heart of the East African Rift Valley, the basin serves as an important frame of reference for the continent. The fossil record from this region plays a key role in our efforts to understand t...
متن کاملSpectral ordering and biochronology of European fossil mammals
—Spectral algorithms have been shown to work well in a wide range of situations that involve the task of ordering. When applied to the localities of a set of European Neogene land mammal taxa, spectral ordering relies almost entirely on the most common genera, depends on connectivity more than on length of taxon lists, and is robust to noise from rarer and less connected taxa. The spectral coef...
متن کاملPrecipitation and large herbivorous mammals II: application to fossil data
Background: We developed a method to estimate precipitation using mammalian ecomorphology, specifically the relative height of the molars of herbivores (see companion paper, this issue). Question: If we apply the new method to paleoenvironments, do the results agree with previous results from fossil mammals and paleobotanical proxies? Data: Large herbivorous fossil mammals of Eurasia. Data from...

Plague hemagglutinating antibodies to a titer of 1:1,024 were demonstrated in 6.6% of buffalo and 0.3% of elephant sera tested 1 year after a plague epidemic in the same area.
