Africa's wild C4 plant foods and possible early hominid diets.
A small minority of Africa's wild plant foods are C4. These are primarily the seeds of some of the C4 grasses, the rootstocks and stem/leaf bases of some of the C4 sedges (especially papyrus), and the leaves of some of the C4 herbaceous dicots (forbs). These wild food plants are commonly found in disturbed ground and wetlands (particularly the grasses and sedges). Multiple lines of evidence ind...
متن کاملC3 grasses have higher nutritional quality than C4 grasses under ambient and elevated atmospheric CO2
Grasses with the C3 photosynthetic pathway are commonly considered to be more nutritious host plants than C4 grasses, but the nutritional quality of C3 grasses is also more greatly impacted by elevated atmospheric CO2 than is that of C4 grasses; C3 grasses produce greater amounts of nonstructural carbohydrates and have greater declines in their nitrogen content than do C4 grasses under elevated...
متن کاملSuperresolution imaging with fluorescent dyes
With the combination of climate change and human encroachment on the territory of endangered species, information about what and where animals eat and how this is changing over time can help guide conservation efforts. Thure Cerling et al. compiled a 6-year record of nitrogen, carbon, oxygen, and hydrogen in the diet of a family of 4 Kenyan elephants by analyzing the isotopic content of the ele...
متن کاملClimate, phylogeny and the ecological distribution of C4 grasses.
'C4 photosynthesis' refers to a suite of traits that increase photosynthesis in high light and high temperature environments. Most C4 plants are grasses, which dominate tropical and subtropical grasslands and savannas but are conspicuously absent from cold growing season climates. Physiological attributes of C4 photosynthesis have been invoked to explain C4 grass biogeography; however, the path...
متن کاملPreference for C4 shade grasses increases hatchling performance in the butterfly, Bicyclus safitza
The Miocene radiation of C4 grasses under high-temperature and low ambient CO 2 levels occurred alongside the transformation of a largely forested landscape into savanna. This inevitably changed the host plant regime of herbivores, and the simultaneous diversification of many consumer lineages, including Bicyclus butterflies in Africa, suggests that the radiations of grasses and grazers may be ...
