PREMISE OF THE STUDY Few previous studies have considered how plant age affects photosynthetic physiology in herbaceous perennials or how photosynthetic capacity in annual cereals compares to perennial relatives. Newly developed perennial cereals offer novel systems for addressing these questions. Our study makes a novel contribution by considering how life history differences affect photosynth...

smirnovia iranica (sabeti) synonym: smirnovia turkestana (bunge) is a deciduous perennial bushy species of the fabaceae (papilionaceae) family. the species grow on sand dunes of desert areas, having a deep vertical root and very long horizontal or lateral roots. they have an important role in natural vegetation of desert and sand dune stabilization. limited growing areas, grazing due to good pa...

— Restoration of floodplain forests has become a primary aim of sustainable forestry in Europe. Although several studies have investigated the conversion of coniferous stands outside of their biogeographical area and on unsuitable sites, none focused specifically on alluvial areas. We surveyed 208 riverine stands, distributed homogeneously throughout the Grand-duché de Luxembourg (western-centr...

Endophytes can provide enhanced drought tolerance, summer survival, and insect and disease resistance to grasses. Endophytes are fungi belonging to the genus Neotyphodium that live in the leaves and stems of grasses and are carried from plant to plant only through seed. These fungi do not cause any disease in the grasses, but under most circumstances they are beneficial to the growth and surviv...

I compared the effectiveness of sympatric brown howlers (Alouatta guariba) and muriquis (Brachyteles arachnoides) as seed dispersers in terms of quantitative and qualitative attributes. I hypothesized that differences in feeding and behavioral patterns between these large-bodied folivorous/frugivorous primates would lead to dissimilarities in their effectiveness as endozoochoric seed dispersal ...
