We used ancient DNA analysis of seven museum specimens of the endangered North American ivory-billed woodpecker (Campephilus principalis) and three specimens of the species from Cuba to document their degree of differentiation and their relationships to other Campephilus woodpeckers. Analysis of these mtDNA sequences reveals that the Cuban and North American ivory bills, along with the imperial...

I appreciate the candor and clarity with which he stated his position and his acknowledgement of its limitations. The purist in the ivory tower has a significant contribution to make concerning ethical problems in our profession but so has the practitioner in the marketplace. I ...

  Ceramic materials due to their high compressive strength and hardness have been one of prime candidates in armor design in particular when high level threads (impact velocity above 600m/s) are involved. The aim of this work is to investigate ballistic impact resistance potential for a target plate with novel ceramic inserts as against ceramic tiles. Two size 98% alumina (AL2O3) base ceramic i...

This overview on Sasanian stuccoes includes the Parthian sites hinting at a transmission of iconographies (i.e., Qaleh-I Zohak and Yazdgird), also with uncertain chronological attribution. On one hand, it underlines lack within Iranian plateau, other how majority was found in western territories.

Information on site fidelity and ranging patterns of wild animals is critical to understand how they use their environment and guide conservation and management strategies. Delphinids show a wide variety of site fidelity and ranging patterns. Between September 2013 and October 2015, we used boat-based surveys, photographic identification, biopsy sampling, clustering analysis, and geographic inf...

despite the lack of a clear understanding of the relationships of eastern and southeastern arabia with different iranian regions during pre-sassanian era and the paucity of written evidence from this period, the huge corpus of archaeological evidence obtained from this region and the few available historical documents show that the region maintained close contacts with iran and was under legal ...
