Data for: Variation in the role of the flag leaf in the reproductive effort of semi-arid rangeland bunchgrasses
<p>This is the complete data set used in the manuscript titled "Variation in the role of the flag leaf in the reproductive effort of semi-arid rangeland bunchgrasses". It includes the responses of total propagule production, percentage of filled and unfilled seeds, and filled seed-specific mass in response to seed head shading and flag leaf removal in two semi-arid perennial bunchgrasses, crested wheatgrass (<em>Agropyron cristatum</em>) and squirreltail wild rye (<em>Elymus elemoides</em>). Seasonal volumetric soil moisture data is also provided.</p>
Distribution. Widespread in the C and W regions of S Africa, reaching to about 15° N in SW Angola. Occupies mainly arid and semi-arid areas, but also occurs in regions with higher precipitation and denser vegetation, such as the fynbos biome of South Africa's Western Cape Province. Cape Foxes have expanded their range over recent decades to the SW, where the species reaches the Atlantic and Indian Ocean coastlines. May occur in SW Swaziland, and possibly also in Lesotho. in Canidae

Data to accompany: Seedling responses to soil moisture amount versus pulse frequency in a dominant semi-arid shrub
<p>The timing, frequency and quantity of rainfall is rapidly changing in dryland regions, leading to profound alterations to dryland plant communities. Understanding dryland plant responses to future rainfall scenarios is crucial for implementing proactive management strategies, particularly in light of intensive changes to land cover concurrent with climate change. One such change is woody plant encroachment, an increasing abundance of woody plant species in areas formerly dominated by grasslands or savannas. The continued encroachment of <em>P.</em> <em>velutina</em> will depend, in part, on seedling capacity to establish and thrive under future climate conditions. Seedling performance is primarily impacted by soil moisture conditions that are governed by precipitation amount (quantity) and frequency. We hypothesized that H1) seedling performance would be enhanced by both greater soil moisture and greater pulse frequency, such that seedlings with similar mean soil moisture would perform best under high moisture pulse frequency. Alternatively, H2) mean soil moisture would have greater influence than pulse frequency, such that at a given pulse frequency would have little influence on seedling performance. The hypotheses were tested by growing 256 <em>P. velutina </em>seedlings under two distinct soil moisture treatments, each of which was maintained by two different pulse frequency treatments. Contrary to H1, mean soil moisture had far greater impact than pulse frequency on seedling growth, photosynthetic gas exchange, leaf chemistry and biomass allocation. These results indicate that <em>P. velutina</em> seedling establishment may be more responsive to rainfall amount than rainfall frequency.</p>
