Tristram's starling (Onychognathus tristramii), also known as Dead Sea starling or Tristram's grackle, is a species of starling native to the Middle East. It is the only member of the genus Onychognathus found mainly outside of Africa. [2] The species is named after Reverend Henry Baker Tristram, who collected natural history specimens. [3]
The family contains 128 species which are divided into 36 genera. Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescent plumage. Starlings are native to Europe, Asia, and Africa, as well as northern Australia and the islands of the tropical Pacific.
The study of plant response in space environments is another subject of astrobotany research. In space, plants encounter unique environmental stressors not found on Earth including microgravity, ionizing radiation, and oxidative stress. [23] Experiments have shown that these stressors cause genetic alterations in plant metabolism pathways.
Zinnia plant in bloom aboard an Earth orbiting space station. The growth of plants in outer space has elicited much scientific interest. [1] In the late 20th and early 21st century, plants were often taken into space in low Earth orbit to be grown in a weightless but pressurized controlled environment, sometimes called space gardens.

In contrast to other brilliant starlings, which feed mainly on fruits, their diet consists mainly of insects and termites. Adult birds catch insects in flight and dig up termite mounds to find prey. [3] Snails, spiders, crustaceans, or small vertebrates, such as lizards, sometimes integrates the diet.
Superb starlings’ eggs are uniformly dark blue, measuring 24–26 millimetres (0.94–1.02 in) x 18–19 millimetres (0.71–0.75 in) and weighting 4.5 g. [15] Females lay 3-4 eggs. [ 12 ] Based on captive breeding, the incubation period lasts 12–13 days, and the surprisingly short nestling period ranges from 18–24 days.
Increasingly frequent and severe heat waves in the Southwest are damaging some desert plants known for thriving in harsh conditions. Saguaro cacti and agave have both suffered in sweltering ...
Protozoan blood parasites of the genus Haemoproteus have been found in common starlings, [81] but a better known pest is the brilliant scarlet nematode Syngamus trachea. This worm moves from the lungs to the trachea and may cause its host to suffocate. In Britain, the rook and the common starling are the most infested wild birds. [82]
