Spanish Imperial Eagle
The Spanish imperial eagle (''Aquila adalberti''), also known as the Spanish eagle or Adalbert's eagle, is a species of eagle native to the Iberian Peninsula. The binomial commemorates Prince Adalbert of Bavaria. Due to its distinct “epaulettes”, old literature often referred to this species as the white-shouldered eagle. Formerly, the Iberian imperial eagle was considered to be a subspecies of the eastern imperial eagle, but is now widely recognised as a separate species due to differences in morphology, ecology, and molecular characteristics. Description This is a large raptor and quite large eagle, broadly similar in size to its cousin, the eastern imperial eagle, which is found in a considerably different distributional range. Compared to sympatric largish booted eagles, it is somewhat smaller than the golden eagle and somewhat larger than the Bonelli's eagle. Spanish imperial eagle can weigh from . The average weight of males in a sample of 10 was while that of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christian Ludwig Brehm
Christian Ludwig Brehm (24 January 1787 – 23 June 1864) was a German pastor and ornithologist. He was the father of the zoologist Alfred Brehm. Life Brehm was born in Schönau near Gotha on 24 January 1787. He was educated at University of Jena to be ordained as minister at Renthendorf in 1813 where he remained until his death on 23 June 1864. He wrote ''Beiträge zur Vogelkunde'' (1820–22), which described 104 species of German birds in minute detail, and ''Handbuch der Naturgeschichte aller Vögel Deutschlands'' (1831) which described 900 bird species Brehm accumulated a collection of 15,000 birds until his death, which included samples from his son, Alfred Brehm. Alfred collected these birds from Sudan, Egypt and throughout Europe. He offered these to the Berlin Zoological Museum on March 1835 because he feared that a storm would destroy his house, but the sale fell through. After his death they remained in the attic of his house, where Otto Kleinschmidt discover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dihedral (aeronautics)
In aeronautics, dihedral is the angle between the left and right wings (or tail surfaces) of an aircraft. "Dihedral" is also used to describe the effect of sideslip on the rolling of the aircraft. Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a ''downward'' angle from horizontal of the wings or tailplane of a fixed-wing aircraft. Dihedral angle has a strong influence on dihedral effect, which is named after it. Dihedral effect is the amount of roll moment produced in proportion to the amount of sideslip. Dihedral effect is a critical factor in the stability of an aircraft about the roll axis (the spiral mode). It is also pertinent to the nature of an aircraft's Dutch roll oscillation and to maneuverability about the roll axis. Longitudinal dihedral is a comparatively obscure term related to the pitch axis of an airplane. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dehesa (pastoral Management)
A ''dehesa'' () is a multifunctional, agrosylvopastoral system (a type of agroforestry) and cultural landscape of southern and central Spain and southern Portugal; in Portugal, it is known as a ''montado''. Its name comes from the Latin 'defensa' (fenced) referring to land that was fenced, and usually destined for pasture. Dehesas may be private or communal property (usually belonging to the municipality). Used primarily for grazing, they produce a variety of products, including non-timber forest products such as wild game, mushrooms, honey, cork, and firewood. They are also used to raise the Spanish fighting bull and the Iberian pig. The main tree component is oaks, usually holm (''Quercus rotundifolia'') and cork (''Quercus suber''). Other oaks, including melojo (''Quercus pyrenaica'') and quejigo (''Quercus faginea''), may be used to form dehesa, the species utilized depending on geographical location and elevation. Dehesa is an anthropogenic system that provides not only a v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
