These trees differ from the birches ( Betula, the other genus in the family ) in that the female catkins are woody and do not disintegrate at maturity, opening to release the seeds in a similar manner to many conifer cones.

These effects have been used by Sepp Holzer for one to allow fruit trees to survive at otherwise inhospitable temperatures and altitudes.

These 26 major types can be reclassified into 6 broader categories: temperate needleleaf ; temperate broadleaf and mixed ; tropical moist ; tropical dry ; sparse trees and parkland ; and forest plantations.

These groups appear as the most primitive eukaryotes on phylogenetic trees constructed using rRNA information, which once suggested that they appeared before the origin of mitochondria.

These palm trees provide shade for smaller trees like peach trees, which form the middle layer.

These data were originally published in Howlett and Majerus ( 1987 ), and an updated version published in Majerus ( 1998 ), who concluded that the moths rest in the upper part of the trees.

These leaves need not be explicit in computer memory — a null child pointer can encode the fact that this child is a leaf — but it simplifies some algorithms for operating on red – black trees if the leaves really are explicit nodes.

These constraints enforce a critical property of red – black trees: that the path from the root to the furthest leaf is no more than twice as long as the path from the root to the nearest leaf.

These travels explain as well how the vinviðir ( wine wood ) the Norse were cutting down in the sagas is actually referring to the vines of Vitis riparia a species of wild grape that grows on trees.

These patterns can be compared and matched ring for ring with trees growing in the same geographical zone and under similar climatic conditions.

These " candles " offer foresters a means to evaluate fertility of the soil and vigour of the trees.

These complex computer programs are encoded in simpler linear chromosomes of fixed length, which are afterwards expressed as expression trees.

These were the first works after Plumier's Genera that used the name Magnolia, this time for some species of flowering trees from temperate North America.

These early techniques have been replaced by newer ones based on mitochondrial DNA sequences and molecular phylogenetics approaches that make use of computational procedures for sequence alignment, construction of phylogenetic trees and calibration of molecular clocks to infer evolutionary relationships.

These fields can be OBVs themselves, forming lists, trees or arbitrary graphs.

These membranes, when outstretched, allow them to glide between trees.

These trees are all over 50 m tall.

These trees provide preferred spring habitat for Black Bear in the San Bernardino Mountains.

These types of disturbances allow Douglas-fir to regenerate in openings, and low-intensity fires often leave Douglas-fir trees standing on drier sites, while less drought-and fire-tolerant species are unable to get established.

These sands cannot support crops, and if the trees are removed erosion is rapid and severe.

These studies further suggest that pollinators may maintain a fidelity to either male or hermaphroditic flowers ( trees ), thus limiting pollination and fruit set under natural conditions where crossing between male and female flowers is required.

These cases are attached to rocks, trees or fences while resting or during their pupa stage, but are otherwise mobile.

" These states of being were " altogether explicable and indefinite " ( like brother and sister ), and it was the fruits of the union of these two entities that created "... the rocks and sands of the earth ; then trees, shrubbery, herbs and grass ; then animals ".

These fundamental ideas -- the indivisibility of sovereignty and its dual ( internal-external ) aspects -- still remain the core of that concept of ultimate political power.

These my grandmother left in their places ( they are still there, more persistent and longer-lived than the generations of man ) and planted others like them, that flourished without careful tending.

These never ceased to suggest that if, in the eyes of Marx and Lenin `` full communism '' was still a very distant ideal, the establishment of a Communist society had now, under Khrushchev, become an `` immediate and tangible reality ''.

These stores are still there, but the volume of the `` downtown store '' has been on a relative decline, while in many cities the suburban `` branch '' sells more and more dry goods.

These are still in wide use today, particularly in semi-rigid formulations, for such applications as cores for sandwich-type structural panels, foamed-in-place insulation, automotive safety padding, arm rests, etc..

These tractors are not entirely satisfactory for plowing, particularly on heavier soils, so you may still want to hire someone to do the plowing.

These pits were also used to steam foods by adding heated rocks or embers and then seaweed or corn husks ( or other coverings ) placed on top to steam fish and shellfish as well as vegetables ; potatoes would be added while still in-skin and corn while in-husk, this would later be referred to as a clambake by the colonists.

These included some for the Triumphs of Maximilian, where he followed the overall style presumably set by Hans Burgkmair, although he was able to escape somewhat from this in his depictions of the more disorderly baggage-train, still coming through a mountain landscape.

These are still used in many developing countries.

These fish can still, however, find their way around by means of their lateral lines, which are highly sensitive to fluctuating water pressure.

These effects are still not yet fully understood ; it is even possible that they also control superconductivity even at low temperatures for some materials.

These adjustments must still obey the double-entry rule.

These terms are still observed, and the collection occupies room 45.

These bright orange buses still display the name of Transportes Urbanos de Sevilla, S. A. M., their former owner, and Seville's coat of arms as a sign of gratitude.

These sort of people are certainly still to be found, but there are many who consider TESOL their main profession.

These tools have been, and still are, offered as on-premises software that companies purchase and run on their own IT infrastructure.

These, as well as his slouching posture, are references to his earlier mild-mannered Pre-Crisis versions, but he still maintains a sense of authority and his assertive self.

These areas have ruins from the wars against the Cathars which are still visible today.

These theories were given credence by the fact that when Germany surrendered in November 1918, its armies were still in French and Belgian territory, Berlin remained 450 miles from the nearest front, and the German armies retired from the field of battle in good order.

These discrete circuits consumed much space and power and were limited in speed, although they are still common in some applications.

These Norse-Gaels had intermarried with the local Gaelic speaking people in Britain, a feature that is still visible in the Faroese genes today, which prove to be mixed Scandinavian-British.

These films may still be banned in the United Kingdom and other countries.

These pronunciations are still used in synagogue ritual and religious study, in Israel and elsewhere, mostly by people who are not native speakers of Hebrew, though some traditionalist Israelis are bi-dialectal.
