High impact information on Hyraxes

• Pregnancy in the hyrax and erythrocyte metabolism of progesterone [1].
• The AQP2 data set, alone as well as in combination with previously published alpha A-crystallin protein sequences, strongly supports a clade consisting of elephant, hyrax, aardvark, and elephant shrew, reaching bootstrap values of 99% [2].
• Conversely, im injection of 250 microgram testosterone induced a fall in LH levels in male hyrax from 1.7 ng/ml to 0.7 ng/ml 6 h after administration [3].
• Intravenous injection of 10 microgram of luteinizing hormone releasing hormone increased mean LH levels in hyrax from 0.9 ng/ml to 23.2 ng/ml by 30 min [3].
• The results indicate that the hyrax cranium resembles the non-human primate cranium in having a steep gradient of strains from the occlusal to orbital regions, but differs from most non-anthropoids in being primarily twisted; the hyrax mandible is bent both vertically and laterally [4].

Biological context of Hyraxes

• Proceedings: Endocrinology of pregnancy in the hyrax; plasma progesterone concentration and erythrocyte metabolism [5].
• Adult males from a colony of lesser rock hyrax found near the equator in Kenya exhibited an annual cycle of testicular activity characterized by intense spermatogenesis and elevated androgen status from May to July [6].

Associations of Hyraxes with chemical compounds

• Chloride was the major anion observed in the foregut; however, the electroneutrality of the mid and hindgut of the hyrax was primarily maintained by the presence of large concentrations of volatile fatty acids produced in these portions of the gut [7].
• (O.) brumpti, a soil-dwelling parasite of the hyrax (Procavia), other terrestrial mammals, and lizards in the Ethiopian Region, the capsule is also virtually unroofed and contains numerous fine pleomorphs [8].

Gene context of Hyraxes

• Islands on the plains: metapopulation dynamics and female biased dispersal in hyraxes (Hyracoidea) in the Serengeti National Park [9].
• CONCLUSION: Hyrax capensis shows only partial development of the gubernacular structures, and, specifically, the primordia of the cremaster sacs remain absent [10].
• The aim of this paper is to introduce a simple device (hyrax expander) and method for mandibular midline distraction [11].
