TL;DR: Solidago altissima (canadensis) is a rhizomatous perennial and introduced in Europe, where it is a serious invader of disturbed sites.

TL;DR: The formation of a new PP cell layer each season, the maintenance of the cells for many years, the early organization of this layer in the primary stem, and the dynamic physiological activity even older cells exhibit supports previous work suggesting that PP cells are an important protective tissue in the secondary phloem.

TL;DR: The results support the interpretation of the perianth of Aristolochia , Euglypha and Holostylis as a trimerous calyx as well as other interpretations in terms of position, morphology, development, and comparison to related taxa.

TL;DR: It is proposed that these breeding system differences are probably linked to the different taxonomic families represented in the understorey strata of these communities and are not a consequence of adaptations to pollination biology or other ecological factors.

TL;DR: The presence of EFNs in this species may be the remnant of a mutualistic interaction with the ants in tropical regions, where the abundance and diversity of ants and herbivores are comparatively higher.

TL;DR: This decrease in LAR counteracted the potential effect on biomass gain of increases in both net assimilation rate and rates of photosynthetic leaf net CO 2 uptake at elevated as compared to ambient CO 2 , particularly in Ficus insipida .

TL;DR: The distribution, anatomy and development of the resin duct system responsible for the resin exudation in Pistacia lentiscus var.

TL;DR: Ranunculus reptans is a stoloniferous perennial herb of inundated lake shores that is native to Central Europe, where it has become a rare and endangered species.

TL;DR: The renewed debated nature of the crust (root versus thallus) is clarified and the root nature is evidenced by the existence of a fringe of root cap cells, the presence of an inner meristem, and the endogenous development of secondary (root-borne) shoots.

TL;DR: The results show that environmental monitoring of permanent plots for the study of long-term vegetation changes must account for interannual variability in species cover.

TL;DR: The results of this study should be used as reference data for further investigations of physiological, biochemical and ultrastructural responses of this species to environmental variations due to pollutants and different altitudinal and exposure situations.

TL;DR: Seasonal activity of cambium was studied in Acacia nilotica (L.) D el .

TL;DR: In this article, the unusual subfoliar position of branches described in Podostemum subulatum (J ager -Z urn 1999) is confirmed in a second representative of Podostemeideae: Sphaerothylax abyssinica.

TL;DR: Viability, germinability and the reserve materials were examined in pollen of Crocus species, finding that shed pollen is rich in lipids and PAS positive polysaccharides, poor in sucrose, glucose and fructose, and completely lacking in starch grains.

TL;DR: Inselbergs are monolithic, old and stable landscape elements with a worldwide distribution that occur as seasonally water-filled depressions with a thin layer of soil mainly inhabited by ephemerals and cryptogams.

TL;DR: Its population in saline lands has smaller individual size, lower density and higher mortality of seedlings than those in other less saline habitats, which indicates that this plant is not a true halophyte.

TL;DR: It is revealed that net photosynthesis (NP) and dark respiration (DR) responses to temperature differed between both species, and NP was strongly depressed at supraoptimal water content.

TL;DR: chemical identification of TLC fractions in the elaiosome of Urochloa paucispicata showed that it contains triglycerides, free fatty acids and diglycerides, and palmitic, oleic and linoleic acids are significant components of the lipid fractions.

TL;DR: Root phosphate (P) uptake capacity was assessed as the rest of the root system was exposed to different mineral nutrient conditions in the form of other nutrient-rich patches (Additional Patches) in a factorial experiment, suggesting that P acquisition occurred in the Additional Patches and that regulation at the whole-plant level reduced the uptake of P from the Primary Patch.

TL;DR: The concept of the ‘Biological Flora of Central Europe’ and a standard format for contributions is presented and it is called for collaboration in a new series: ‘The biological flora of Central European’.

TL;DR: It is supposed that the increase in absorbance of ultraviolet-B-radiation is caused by an increase in ultraviolet- B radiation in the Hunsruck.

TL;DR: The induction of haustoria formation in Cuscuta reflexa proved to be independent of the presence of a suitable potential host, and an interaction of IAA and cytokinine, possibly involved in the regulation of these processes, is discussed.

TL;DR: Dramatic ecophysiological differences expected as a result of photosynthetic pathway alone were not observed in this in situ study of C3 and C4 prairie species in northeastern Kansas.

TL;DR: A synopsis of the poorly known genus Linnaeopsis, endemic to the Uluguru Mts.

TL;DR: A study of the root-tuber, rhizome and root-cluster orchids demonstrated essential structural resemblance of their monocarpic shoots and particularities of their regeneration.

TL;DR: At the interspecific and intraspecific level, total seed mass per infructestence and also infructescence mass was most strongly correlated with mean seed size rather than with the number of seeds per infruotescence, suggesting that pleiotropy is more important than negative trade-offs as an explanation for this pattern.

TL;DR: The reactions of growth and water relations to drought were tested in young plants of four deciduous tree species, which occur at drought-caused tree-line sites in Central Europe on shallow calcareous soils and none of the species was osmotic adjustment found as an adaptation to drought stress.
