A new remarkable dwarf sedge (Carex phylloscirpoid, Cyperaceae) from Northern Chile, with insights on the evolution of Austral section Racemosae
<p>We describe a new remarkable dwarf and apparently acaulescent species of <i>Carex</i> (Cyperaceae)<i> </i>from the Andes of northern Chile: <b><i>Carex phylloscirpoides</i></b>. Morphological and molecular data (two nuclear and three plastid DNA regions) were used to study the phylogenetic placement and systematic relationships of this species, which resulted in its assignment to section <i>Racemosae</i>. However, despite being related to the other three species of the section present in the Southern Cone based on phylogenetic evidence, it displays a number of unusual morphological features. In addition, it is geographically disjunct and genetically differentiated from them. A conservation assessment was performed which resulted in the proposal of the Critically Endangered category at the global level under IUCN guidelines. We discuss the biogeographic and ecological peculiarities of the new species and its allies, with emphasis in the high number of acaulescent sedges present in South America. The features of <b><i>C. phylloscirpoides</i> </b>emphasize its unique evolutionary position and its rarity highlights its conservation importance, especially in the context of the South American Andean flora.</p>
Plant herbivore interactions: Combined effect of ground water level, root vole grazing and sedge silicification
<p>1. Accumulation of silica (Si) by plants can driven by (1) herbivore pressure (and therefore, plant-herbivore interactions) (2) geo-hydrological cycles or (3) a combination of (1) and (2), with (1-3) possibly affecting Si concentration with a 1-year delay.</p> <p>2. To identify the relative significance of (1-3) we analysed the concentration of Si in fibrous tussock sedge (<em>Carex appropinquata</em>), the population density of the root vole (Microtus oeconomus) and the ground water level, over 11 years.</p> <p>3. The largest influence of autumn Si concentration in leaves (Sileaf) was the level of the current year's ground water table, which was positive and accounted for 13.3% of its variance. The previous year's vole population density was weakly positively correlated with Sileaf and alone explained 9.5% of its variance.</p> <p>4. The only variable found to have a positive, significant effect on autumn Si concentration in rhizomes (Sirhiz) was the current year spring water level explaining as much as 60.9% of its variance.</p> <p>5. We conclude that the changes in Si concentration in fibrous tussock sedge are predominantly driven by hydrology, with vole population dynamics being secondary.</p> <p>6. Our results provide only partial support for the existence of plant-herbivore interactions, as we did not detect the significant effects of Si tussock concentration on the vole density dynamics. This was mainly due to low level of silification of sedges, which was insufficient to impinge herbivores.</p> <p>7. Future studies on plant-herbivore interactions should therefore aim at disentangling whether anti-herbivore protection is dependent on threshold values of herbivore population dynamics. Furthermore, studies on Si accumulation should focus on the effect of water-mediated Si availability.</p>

FIGURE 2. Comparison of the spikelets (a & c) and rachillas (b & d) of two fibrous "Pycreus" species clearly showing the difference between Cyperus fibrillosus (a & b) and C. scaettae (c & d). Cyperus fibrillosus has a flexuous rachilla that is hardly visible between the glumes. Lower glumes mostly have 1–2 additional nerves on their wings. Cyperus scaettae has larger spikelets with strongly imbricate glumes and a straight rachilla that is visible between the glumes.
