The physiological mechanisms controlling plant responses to dynamic changes in ambient solar ultraviolet (UV) radiation are not fully understood: this information is important to further comprehend plant adaptation to their natural habitats. We used the fluorimeter Dualex to estimate in vivo the epidermal flavonoid contents by measuring epidermal UV absorbance (A375) in Betula pendula Roth (silver birch) leaves of different ages under altered UV. Seedlings were grown in a greenhouse for 15 days without UV and transferred outdoors under three UV treatments (UV‐0, UV‐A and UV‐A+B) created by three types of plastic film. After 7 and 13 days, Dualex measurements were taken at adaxial and abaxial epidermis of the first three leaves (L1, L2 and L3) of the seedlings. After 14 days, some of the seedlings were reciprocally swapped amongst the treatments to study the accumulation of epidermal flavonoids in the youngest unfolded leaves (L3) during leaf expansion under changing solar UV environments. ...
Three species of autoecious aphids, Callipterinella calliptera (Hartig), Euceraphis betulae (Koch), and Betulaphis brevipilosa Börner, commonly occur on European white birch trees, Betula pendula Roth, in northern California. Populations were sampled from 1981 through 1984 at two sites. Within-tree populations of all three species were more abundant in the lower and middle vertical thirds of tree canopies. Optimal sample sizes were estimated for individual trees as well as tree populations, given variable mean aphid densities, sampling reliability levels, and sampling costs. An aesthetic injury level for honeydew production was estimated. At both sites, all species exhibited spring and fall peaks with a summer decline in numbers. Callipterinella calliptera and B. brevipilosa populations increased during late summer while feeding on mature leaves. Euceraphis betulae preferred developing and senescing leaves and was reproductively

An assemblage of tree species with different crown properties creates heterogeneous environments at the canopy level. Changes of functional leaf traits are expected, especially those related to light interception and photosynthesis. Chlorophyll a fluorescence (ChlF) properties in dark-adapted leaves, specific leaf area, leaf nitrogen content (N) and carbon isotope composition (delta C-13) were measured on Picea abies (L.) H. Karst., Pinus sylvestris L. and Betula pendula Roth. in monospecific and mixed boreal forests in Europe, in order to test whether they were affected by stand species richness and composition. Photosynthetic efficiency, assessed by induced emission of leaf ChlF, was positively influenced in B. pendula by species richness, whereas P. abies showed higher photosynthetic efficiency in monospecific stands. Pinus sylvestris had different responses when it coexisted with P. abies or B. pendula. The presence of B. pendula, but not of P. abies, in the forest had a positive effect on ...
To elucidate the mechanisms underlying the population dynamics of Betula ermanii in response to climate change over temporal and spatial dimensions, 310 quadrats were systematically sampled in 7 plots located in the upper treeline region on the north-facing slopes of Changbai Mountains. IKONOS images were used to identify the spatial distribution of Betula ermanii with the aid of a digital elevation model (DEM). Meteorological data were recorded in the field throughout the study area and collected from a nearby long-term weather station, to reconstruct the temperature and precipitation changes. We collected tree-ring samples from a total of 1197 Betula ermanii trees. The correlation coefficients between 14 eco-climate parameters (from 1953 to 2008) and the aggregated annual indices of population dynamics for each quadrat (totaling 310 quadrats) in the corresponding years were calculated via statistical analysis facilitated by GIS technology. The results show that the Betula ermanii population is ...

Bud dynamic in mountain birch, Betula pubescens ssp. czerepanovii, is affected by biotic and abiotic factors such as temperature, light and herbivory. Climate probably has a large impact on module life history strategies i.e. survival, sexual and vegetative reproduction. (Modules are here defined as partially autonomous, repetitive and multicellular subunits within a tree.) Trade-off between present reproduction and future growth and/or reproduction occurs if resources are limiting. There is no direct trade-off between male catkin production and axillary bud production in mountain birch since male catkins are produced at the terminal bud of long-shoot. This bud is aborted when no catkin is present. However, same resources are used for both male catkin production and axillary bud production indicating that trade-offs occur in mountain birch. In my study I have simulated herbivory in order to study what effect trade-offs have on growth of long-shoot and bud performance.
Betula papyrifera trees were exposed to elevated concentrations of CO2 (1.4 x ambient), O3 (1.2 x ambient) or CO2 + O3 at the Aspen Free-air CO2 Enrichment Experiment. The treatment effects on leaf surface characteristics were studied after nine years of tree exposure. CO2 and O3 increased epidermal cell size and reduced epidermal cell density but leaf size was not altered. Stomatal density remained unaffected, but stomatal index increased under elevated CO2. Cuticular ridges and epicuticular wax crystallites were less evident under CO2 and CO2 + O3. The increase in amorphous deposits, particularly under CO2 + O3, was associated with the appearance of elongated plate crystallites in stomatal chambers. Increased proportions of alkyl esters resulted from increased esterification of fatty acids and alcohols under elevated CO2 + O3. The combination of elevated CO2 and O3 resulted in different responses than expected under exposure to CO2 or O3 alone. ...

Birch polypore (Piptoporus betulinus) growing on the trunk of a silver birch tree (Betula pendula). This parasitic bracket fungus is found only on birch trees. The visible part of the fungus is the fruiting body that produces the spores, which are held in pores on the underside of the bracket. The fungus uses a fine mycelium network to extract nutrients from the trunk of the tree. It is generally only found on weakened trees, and the fungus can kill a birch tree over time. - Stock Image B250/1623

In a diversity of habitats, from lowland hardwoods, especially in the southern part of the state, to hemlock-white pine-northern hardwoods forest of the north, becoming especially common in the western Upper Peninsula. As is true of the other birches, the pistillate scales and bark of B. alleghaniensis are variable. Very old trees, as in virgin stands in the Upper Peninsula, may have very furrowed or checkered dark bark. Trees in swamps of the southern Lower Peninsula may have dark brown or blackish bark, which peels very little if at all; such trees hardly resemble the widespread typical yellow birch with light yellow-brown, peeling bark, and have sometimes been erroneously referred to B. lenta (which differs in having smaller, nearly or quite glabrous and less densely ciliate scales in the pistillate aments). Betula lenta and B. alleghaniensis both have a characteristic odor and flavor of wintergreen in the crushed bark of young twigs. Betula nigra, river birch, lacks the wintergreen flavor ...
1H4B: Solution Structure, Dynamics, and Hydrodynamics of the Calcium-Bound Cross-Reactive Birch Pollen Allergen Bet V 4 Reveal a Canonical Monomeric Two EF-Hand Assembly with a Regulatory Function
Caloptilia betulicola, the red birch slender, is a moth of the Gracillariidae family. It is found from Scandinavia and the north of European Russia to the Pyrenees and Alps and from Ireland to Poland and Slovakia. In the east it is found up to China, Japan and the Russian Far East. The wingspan is 14-16 millimetres (0.55-0.63 in). There are two generations per year, with adults on wing in June and July and again in September and October. The larvae feed on Betula pendula and Betula pubecens. They mine the leaves of their host plant. The mine starts with an inconspicuous epidermal corridor. Later, a blotch is formed, that quickly develops into a tentiform mine. Generally, the mine is lower-surface, but upper-surface mines are not rare. The frass is deposited in a mass of grains in a corner of the mine. After leaving the mine, the larva moves twice. First it lives in a rolled or folded leaf margin and later in a leaf that is rolled downwards, starting from the leaf tip. Pupation takes place in a ...

Woschnagg, C.; Rak, S.; Venge, P., 1996: Oxygen radical production by blood eosinophils is reduced during birch pollen season in allergic patients
All patients were clinically diagnosed as birch pollen allergic. Seven patients allergic to birch pollen without any gastrointestinal symptoms and seven completely healthy individuals were included in the study for comparison. All patients were examined with a standard skin prick test panel and blood samples were analysed for IgE antibodies by component micro-arrays (ISAC). The two groups of patients underwent gastroscopy and duodenal biopsies were taken both during (May-June) and outside the pollen season (November-January) for each patient. Duodenal biopsies were examined with immunostaining for mast cells (IgE and tryptase), eosinophils (eosinophil peroxidase), T-cells (CD3), and dendritic cells (DC) (CD11c). ...
One example of a diagnostic application of recombinant birch allergens is found in a study examining allergen-specific serum IgE antibodies using the recombinant allergens Bet v 1, Bet v 2 and Bet v 4, as examined in birch-sensitive patients from the province of Cuneo, in northwestern Italy. It was reported that of 372 patients, 215 (58%) had serum IgE antibodies to Bet v 1, 166 (45%) to Bet v 2, and 35 (9%) to Bet v 4. Mono-sensitisation to Bet v 1 occurred in 146 (39%) of patients; in 96 (26%) to Bet v 2; and in only 4 (1%) to Bet v 4. Thirty-nine sera (11%) did not contain allergen-specific IgE antibodies to any of these three individual birch pollen allergens. All 372 sera (100%) had IgE antibodies against natural Birch pollen extract; 162 (44%) contained IgE antibodies reacting with Apple extract (75% of Bet v 1 positive sera). The study concluded that the 3 recombinant birch pollen allergens alone could identify 90% of birch pollen-sensitive patients (7 ...

inproceedings{41c8c41b-a2f5-4475-8be9-0341dfcd092f, abstract = {In northern Sweden, Empetrum hermaphroditum Hagerup dominates the ground layer vegetation in post fire successions by suppressing other plant species. Previous studies suggest that this negative effect by E. hermaphroditum may be explained, at least in part, by the release of phenolic compounds, particularly batatasin-III, from foliage to soil. In this pilot study, we evaluated the effect of batatasin-III on photosynthesis by applying the compound (0.1, 1.0, or 2.8 mM) directly to the transpiration stream of intact Spinacia oleracea L. (spinach) and Betula pendula L. (birch) leaves. Within the concentration range used, batatasin-III had a small, but significant, effect on photosynthesis. The strongest effect was found on CO2 assimilation, but there were also significant effects on respiration and on maximum quantum yield of chlorophyll fluorescence (Fv / Fm). In spinach leaves treated with 2.8 mM of batatasin-III, a 14 % decrease in ...

Betula populifolia, commonly called gray birch, is a short-lived, narrow-columnar, suckering, deciduous tree that typically grows to 20-40 tall. It most often appears in a multi-trunked form, but also grows with a single trunk. It is native primarily from Southeastern Canada to Virginia, with a scattering of plants extending westward to Illinois. It typically occurs in both dry and wet soils. This tree is noted for (1) its non-peeling chalky white bark with dark chevron trunk patches appearing below each branch base and (2) its long-pointed triangular green leaves. Triangular leaves (each to 3" long) are double-toothed and shiny with tapered tips. Fall color is usually undistinguished. Tiny monoecious flowers appear in early spring in separate catkins on the same tree: yellowish-brown male flowers in single catkins (to 4" long) at the branch tips and greenish female flowers in smaller, upright catkins (to 1/2" long). Female flowers are followed by drooping cone-like fruits containing numerous ...
