Allactaginae is a subfamily of dipodids consisting of four-and five-toed jerboas(Allacta.a. Allactodipus,Orientallacta.a. Pygeretmus, Scarturus) found in open habitats of Asia.a.d North Africa. Recent molecular phylogenies have upended our understanding of this group's systematics across taxonomic scales. Here, I used cranial geometric morphometrics to examine variation across 219 specimens of 14 allactagine species(Allacta.a.major, A. severtzovi, Orientallacta.a.balikunica, ***, O. sibirica, Pygeretmus platyurus, P. pumilio,P. shitkovi, Scarturus a.a.ychensis, S. euphraticus,S. hotsoni, S. indicus, S. tetra.a.tylus, S. williamsi)in light of their revised taxonomy. Results showed no significant sexual size or shape dimorphism. Species significantly differed in cranial size and shape both overall and as species pairs. Species identity had a strong effect on both cranial size and shape. Only a small part of cranial shape variation was allometric,with no evidence of unique species allometries, and most specimens fit closely to the common allometric regression vector. Allacta.a.was the largest,followed by Orientallacta.a. Scarturus, and finally Pygeretmus. Principal component 1(PC1) sepa.a.ed O. bulla.a.O. balikunica+S. hotsoni(with inflated bullae along with reduced zygomatic arches and rostra) from A. major+A. severtzovi+O. sibirica(with converse patterns), while PC2 differentiated Orientallacta.a.with enlarged cranial bases and rostra.a.ong with reduced zygomatic arches and foramina magna) from Scarturus+Pygeretmus(with the opposite patterns). Clustering based on the unweighted pair group method with arithmetic mean(UPGMA) contained the four genera, but S. hotsoni clustered with O. bulla.a.O. balikunica.a.d *** clustered with A. major+A. severtzovi, likely due to convergence and allometry, respectively.

Ophiolites play a key role in understanding subduction-accretion-collision processes. Herein, we discuss origin and metamorphic evolution of an enigmatic, Neoproterozoic ophiolite candidate—the mafic-ultra.a.ic Songshugou Complex, Qinling belt, China—summarizing published thermobarometr);U/Pb geochronology, and geochemistry and presenting new phase equilibrium modeling. Garnet, rarely preserved in amphibolites of the Songshugou Complex, has prograde zoning and low-pvrope cores |Alm54-71(Grs+And)25-30PrP1-6Sps5-12. It formed at quartz eclogite facies conditions of 1.93-2.54 GPa, 462-542℃. During exhumation, garnet first was mantled by plagioclase-rich coronas at about 0.7-1.2 GPa, 660-710℃. During an isothermal uplift to 0.5-0.8 GPa, these coronas evolved widely into n-shaped aggregates and eventually into whitish ribbons oriented with a steeply southwest dipping mineral stretching lineation. The exhumation into middle-upper crustal levels proceeded till the Late Devonian. The oceanic protoliths of the eclogites were emplaced into continental crust in the Neoproterozoic and dragged into a subduction zone in North Qinling in the Cambrian. The ultra.a.ic rocks of the Songshugou Complex were not subducted with the mafic rocks in a coherent block given the absence of garnet but ubiquitous occurrence of spinel implies a P maximum of ?1.7 GPa. Rather, mafic and ultra.a.ic rocks belonged to downgoing and overriding plate, respectively. They were juxtaposed at 0.8-1.7 GPa.a. Early Ordovician time.

Varicocele is a common problem in reproductive medicine practice. A varicocele is identified in 15% of healthy men and up to 35% of men with primary infertility. The exact pathophysiology of varicoceles is not very well understood, especially regarding its effect on male infertility. We have conducted a systematic review of studies evaluating the epidemiology of varicocele in the general population and in men presenting with infertility. In this article, we have identified some of the factors that can influence the epidemiological aspects of varicoceles. We also recognize that varicocele epidemiology remains incompletely understood, and there is a need for well-designed, large-scale studies to fully define the epidemiological aspects of this condition.
