“…Gould & Kapadia (1964) included 12 species in their morphologically variable, B. curtipendula complex (B. sect. Bouteloua), and it has been hypothesized that hybridization has played a major role in the evolution of this group (Gould, 1980;Siqueiros-Delgado, 2001, 2007Siqueiros-Delgado et al, 2013). We include for the first time, the Central and South American, B. swallenii in this complex.…”

Bouteloua (Poaceae: Chloridoideae: Cynodonteae; Boutelouiane) is an important genus of forage grasses containing 60 species found primarily in the Americas with a center of diversity in northern Mexico. A modern subgeneric classification is lacking. The goals of our study were to reconstruct the evolutionary history among the species of Bouteloua using molecular data with increased species sampling compared to previous studies. A phylogenetic analysis was conducted on 209 samples, of which 59 species (206 individuals) were in Bouteloua, using two plastid (rpl32‐trnL spacer and rps16‐trnK spacer) and nuclear ITS 1&2 (ribosomal internal transcribed spacer) sequences to infer evolutionary relationships and produce a subgeneric classification. Overall, ITS and plastid phylogenies rendered similar patterns. However, the ITS phylogeny lacked backbone structure, recovering only four internal clades out of nine found in the plastid phylogeny. The ITS network shows a radiative evolutionary pattern and indicates a number of incompatible splits, suggesting past hybridization between species of different sections. The maximum‐likelihood tree from the combined plastid and ITS regions is well resolved and depicts a strongly supported monophyletic Bouteloua that includes ten strongly supported clades and one moderately supported clade. The molecular results support the recognition of 10 sections and two subsections within Bouteloua s.l.; three sections are new: Barbata, Hirsuta, and Trifida; four sections are new combinations: Buchloe, Cyclostachya, Opizia, and Triplathera; and two subsections are new: Eriopoda and Hirsuta. Based on our molecular results and the possession of unique morphological characters we describe a new species from Nuevo León, Bouteloua herrera‐arrietae.

“…(black grama) at population and clonal levels in Chihuahuan Desert grasslands of southern New Mexico. This stoloniferous, perennial C 4 grass is abundant in Chihuahuan and Sonoran Desert grasslands of Texas, New Mexico, Arizona, and northern Mexico and is a key forage species for livestock (Gould 1979;USDA-NRCS 2004). Resprouting responses were compared between burned and unburned areas, both exposed to and excluded from cattle grazing.…”

Population and clonal level responses of a perennial grass following fire in the northern Chihuahuan Desert

Relationships involving fire and perennial grasses are controversial in Chihuahuan Desert grasslands of southern New Mexico, USA. Research suggests that fire delays the resprouting of perennial grasses well after two growing seasons. However, such results are confounded by livestock grazing, soil erosion, and drought. Additionally, post-fire grass responses may depend on initial clone size. We evaluated the effects of fire, grazing, and clone size on Bouteloua eriopoda (black grama) in southern New Mexico grasslands. Four 2-ha plots were established in each of four sites. Fire and grazing were applied or not applied in 1999 such that four treatment combinations were assigned randomly to plots within each site. Within each plot, small (0-10 cm(2) basal area), medium (10-30 cm(2)), and large ( > 30 cm(2)) clones were initially mapped in five 0.91-m(2) quadrats where grass attributes and litter cover were evaluated before and at the end of two growing seasons following fire. Maximum fire temperature was also measured. At a population level, canopy and litter cover were each approximately 50% less in burned than unburned areas. However, compared to initial levels, canopy height had increased by 10% at the end of the study, regardless of fire. At a clonal level, basal cover reductions were attributed mostly to large clones that survived fire. Smaller clone densities had decreased by as much as 19% in burned compared to unburned areas, and fire reduced the basal cover of medium clones. Basal and canopy cover, recruitment, and clone basal area decreased with increased fire temperatures. Almost all responses were independent of grazing, and interactive effects of grazing and fire were not detected. Fire did not kill all perennial grass clones, regardless of size. However, rapid responses were likely influenced by above-average precipitation after fire. Future studies in desert grasslands should examine how perennial grass dynamics are affected by fire, precipitation patterns, and interactions with grazing.
