Newlander Thesis FINAL
ABSTRACT In many Mojave Desert ecosystems, water infiltrates to root-zones in greatest proportion via washes. As such, washes have a pronounced effect on plant dispersion and size across these landscapes. Desert roads alter the natural spatial patterns of washes on alluvial fans (locally called bajadas) and potentially affect plant production and distribution. As a winter-rainfall dominated ecosystem, climate changes in the Mojave Desert that increase summer precipitation may also play an important role in altering vegetation processes influenced by washes. Road effects on the spatial distribution of desert plants on a Mojave Desert bajada were examined using remotely sensed LiDAR data and ground based measurements of plant size. Plant physiological responses to summer wash flow were also quantified by measuring gas exchange and water status of two dominant perennial species, Larrea tridentata and Ambrosia dumosa. Larrea and Ambrosia plants were nearly 7x and 4x larger where wash flow has been enhanced by road culverts, relative to undisturbed areas and areas where flow has been cut-off by the presence of a road/railroad. Clustering of large plants occurred along wash margins, with clustering most pronounced in areas of enhanced wash flow. No clustering was found where wash flow has been eliminated. For ecophysiological traits, both species showed pronounced responses to the pulse of water; however, these responses varied as a function of distance from wash. Larrea plants within 3 m and Ambrosia plants within ca. 2 m from the wash responded to the pulse of water. Leaf phenology dictated the timing ii of carbon gain as Larrea experienced a rapid but short-lived increase in stomatal conductance compared to a significant response for over a month following the pulse for Ambrosia. -

This species richness compares with the more tropical regions of southern Mexico (e.g., Bajío region, Veracruz) and Central America (Costa Rica, Nicaragua). Convolv species occur in a diverse range of plant communities from intertidal zones to mountain conifer forest, with highest diversity in tropical deciduous forest and oak woodlands in ten major vegetation types: tropical deciduous forest (44), oak woodland (34), Sonoran desert (33), foothills thornscrub (31), coastal thornscrub (30), pine-oak forest (27), grassland (13), Chihuahuan desert (11), coastal salt scrub and mangroves (1), and mixed conifer forest (1). -

Extent of aeolian deposits in East Anglia Andreas J. Scheib and Jonathan R. Lee During the Late Pleistocene glacial period, East Anglia lay largely beyond the southern limit of the British Ice Sheet, with ice impinging on the north Norfolk coast between Cley and the eastern fringes of the Wash Introduction Basin (Straw, 1960; Brand et al., 2002; Riding et al., 2003; Pawley et al., The ‘European Coversand Sheet’ is a discontinuous ‘sheet’ of aeolian 2006). Although much of East Anglia wasn’t glaciated, it was subjected (windblown) loess and coversand that extends through eastern and to intense periglacial processes that resulted in the localised generation southern England, across the English Channel into northern France, of patterned ground and other periglacial phenomena such as pingos Belgium and the Netherlands (Kasse, 1997; Antoine et al., 2003).

Accepted: August 4, 2016) aBstRact. The Atriplex littoralis L. is a rare and endangered species in Poland and many other countries in Europe. In Poland it is mainly found on the west coast and also rarely in central parts. It has been seen in Puck Bay and the Gulf of Gdańsk as well as in Hel Peninsula. The grassleaf orache is a halophyte, terophyte and a sunlight-loving plant. Data shows that apart from on the coast, this species may also appear in in- land areas, for example on ruderal habitats such as roadsides. The results of our observations confirm the presence of the species on beaches and rocky bank reinforcement, with accumulation of annual vegetation in the Hel Peninsula and Puck Bay. Five sites, where Atriplex littoralis specimens occur have been found. In each site 1 to 15 specimens where found, in total 31. Five phytosociological relevés were made within the floristically poor patches of Matricario maritimae-Atriplicetum littoralis (Christiansen 1933) R.Tx. 1950.

The Influence of Stream Channels on Larrea and Ambrosia Distributions

Schwinning,1* D. R. Sandquist,2 D. M. Miller,3 D. R. Bedford,3 S. L.

Resource Blvd, Moab, UT 84532, USA ABSTRACT Drainage channels are among the most conspicuous surficial features of deserts, but little quantitative analysis of their influence on plant distributions is available. We analysed the effects of desert stream channels (‘washes’) on Larrea tridentata and Ambrosia dumosa density and cover on an alluvial piedmont in the Mojave Desert, based on a spatial analysis of transect data encompassing a total length of 2775 m surveyed in 5 cm increments. Significant deviations from average transect properties were identified by bootstrapping. Predictably, shrub cover and density were much reduced inside washes, and elevated above average levels adjacent to washes. Average Larrea and Ambrosia cover and density peaked 1Ð2–1Ð6mand0Ð5–1Ð0 m from wash edges, respectively. We compared wash effects in runon-depleted (R) sections, where washes had been cut off from runon and were presumably inactive, with those in runon-supplemented (CR) sections downslope from railroad culverts to help identify mechanisms responsible for the facilitative effect of washes on adjacent shrubs. -
