Hominins living on the sedge.
T he evolution of C4 photosynthesis was a signal shift in the history of life on Earth, including at least 50 independent origins in 19 families of higher plants (1). Today, C4 plants account for a quarter of the primary productivity on the planet despite representing a small fraction (∼3%) of the estimated 250,000 land plant species (2). Most C4 plants are grasses (family Poaceae, 4,500 specie...
متن کاملMicrosatellite primers for the rare sedge Lepidosperma bungalbin (Cyperaceae)1
PREMISE OF THE STUDY Microsatellite markers were developed for the rare sedge Lepidosperma bungalbin (Cyperaceae) to assess genetic variation and its spatial structuring. METHODS AND RESULTS We conducted shotgun sequencing on an Illumina MiSeq and produced 6,215,872 sequence reads. The QDD pipeline was used to design 60 primer pairs that were screened using PCR. We developed 17 loci, of which...
متن کاملAdaptive settlement in sedge warblers Acrocephalus schoenobaenus—focus on the scale of individuals
Breeding site selection can be linked to population dynamics through pre-emptive site selection, by which an individual selects the best (in terms of fitness) available site, preventing others from sharing it. We examined the pattern of territorial settlement and its fitness consequences during a study of sedge warblers Acrocephalus schoenobaenus inhabiting two study plots in the Nida Wetlands ...
متن کاملCarbon dioxide assimilation by a wetland sedge canopy exposed to ambient and elevated CO
1. The wetland sedge Scirpus olneyi Gray displays fast rates of CO 2 assimilation and responds positively to increased atmospheric CO 2 concentration. The present study was aimed at identifying the ecophysiological traits specific to S. olneyi that drive these CO 2 -assimilation patterns under ambient and elevated CO 2 conditions. 2. The net ecosystem exchange (NEE) of CO 2 between S. olneyi co...
متن کاملEnvironmental regulation of C(3) and C(4) differentiation in the amphibious sedge Eleocharis vivipara.
The biochemical and physiological characteristics of C4 photosynthesis have been researched and clarified in detail. We now know that the differentiation of two cell types, mesophyll cells (MC) and bundle sheath cells (BSC), is required for efficient C4 photosynthesis. Thus, the leaves of C4 plants have more complicated structural and functional features than those of C3 plants (Hatch, 1999; Ka...
