“…Recent phylogenetic estimates based upon molecular data (Bell 2007;Columbus et al 2007;Peterson et al 2010; GPWG II 2011) support inclusion of Swallenia in a group consisting of Blepharidachne Hack., Dasyochloa Willd. ex Rydb., Erioneuron Nash, Munroa Torr., and Scleropogon Phil.…”

Genetic Diversity in Swallenia alexandrae (Poaceae, Chloridoideae), a Narrow Endemic From the Eureka Dunes (Inyo County, California)

Swallenia alexandrae, Eureka Valley dune grass (Poaceae, Chloridoideae), is a narrow endemic known only from three localities in the Eureka Valley and adjoining Saline Range in the northern portion of Death Valley National Park (Inyo County, California). This monotypic genus is listed as endangered by the US Fish and Wildlife Service and as rare by the California Department of Fish and Game. Genetic diversity within and among populations of S. alexandrae was studied with randomly amplified polymorphic DNA. A single polymorphic band was detected in approximately one quarter of all individuals sampled. This result indicates very low genetic diversity in S. alexandrae. There is no evidence of private alleles and very little partitioning of genetic diversity between populations. These results are discussed in relation to conservation concerns for S. alexandrae.

“…Amongst all the grass species currently recognized in the tribe, about 67% are contained in the three largest genera Eragrostis (350 species), Muhlenbergia (160 species) and Sporobolus (160 species) (Peterson et al 1997). A newer classification based on DNA phylogenies includes about 20 genera in Eragrostideae, with three subtribes (Peterson et al 2010(Peterson et al , 2010a(Peterson et al , 2011(Peterson et al , 2012 and excludes Muhlenbergia and Sporobolus that have been moved to Cynodonteae and Zoysieae, respectively (Peterson et al 2010b).…”

Morphometric analysis of caryopsis in some species of Eragrostis (Poaceae)

Seed exomorphic characters of nine different species of Eragrostis were investigated by Light and Scanning electron microscopy. In the present study the micro-morphological characteristic features of caryopses such as shape, dimension, colour, epidermal cell surface structure and features of anticlinal and periclinal walls were examined. Light microscopy revealed that most of the studied caryopses varied in shape from obloid to ovoid. The caryopses in most of the species of Eragrostis are sticky in nature due to the presence of surface slime cells, which makes them appear shiny and transparent. This morphological feature was able to be observed under SEM but not light microscopy. The nine different species could be differentiated on the basis of shape and position of the hilum and embryo.

“…There is a strong association between C 4 variants and their subordinate subfamilies. Almost all C 4 species of Chloridoideae are NAD-ME or PCK subtype, while the vast majority of C 4 species of Aristidoideae, Arundinoideae, and Panicoideae are NADP-ME subtype (Prendergast et al 1987;Kellogg 1999;Taub 2000;Peterson et al 2010). The presence of NADP-ME panicoid species in one climatic type might limit other NADP-ME panicoid species from dispersing into that space, e.g.…”

“…The currently accepted phylogeny of Poaceae shows two well-supported clades: Bambusoideae, Ehrhartoideae, and Pooideae (BEP) and Panicoideae, Arundinoideae, Chloridoideae, Micrairoideae, Aristidoideae, and Danthonioideae (PACMAD) (Sánchez-Ken et al 2007;Bouchenak-Khelladi et al 2008;Soreng et al 2009;Peterson et al 2010;Sánchez-Ken and Clark 2010). Modern phylogenetic analyses show that grass diversity is regulated by a complex set of factors indirectly related to the photosynthetic pathway at different spatial scales (Crisp et al 2009;Edwards and Smith 2010).…”

Explaining relationships between species richness and biogeographical patterns over a broad geographic scale is a central issue of biogeography and macroecology. We document the realized climate niches for grasses in China's nature reserves and discuss its formation mechanism using grass richness data combined with climatic, physiological, and phylogenetic data. Our results suggest that climate niche structure of grasses is phylogenetically conservative for BEP (Bambusoideae, Ehrhartoideae, and Pooideae) and PACMAD (Panicoideae, Arundinoideae, Chloridoideae, Micrairoideae, Aristidoideae, and Danthonioideae) clades along temperature gradients and for Chloridoideae and Panicoideae along precipitation gradients. At the national scale, the divergence patterns of climate niches between two major clades are more distinguishable than between C 3 and C 4 grasses. High rates of climate niche evolution are found in C 4 clades in the subtropical forest region. There appears to be a strong association between elevation gradients and grass diversity: the specific environmental conditions (e.g. energy) and the rapid shifts of climate conditions drive high grass diversification. Evolutionary conservatism of climate niches may be influenced by the specific adaptive ability to changing environmental conditions within NAD-ME/NADP-ME clades. Our results indicate that adaptations to major climate changes may be accomplished by C 4 grass nodes of high climate niche evolutionary rates in China's nature reserves.
