C. liops is the most common species of Priscacara within the Green River lacustrine deposits and at certain locations it outnumbers P. serrata by over 3:1. The two species differ in the number of dorsal and anal fin rays, as well as possibly a coarser …

与P. humanus相比，两个P. serrata基因组明显更大（139 Mbp vs. 111 Mbp）并且编码更多数量的基因。与P. humanus类似，它们在视觉和嗅觉等感官相关类别中显着减少。利用全基因组基因组，我们对P. serrata谱系进行系统发育重建和进化测年。

2024年11月17日 · Priacma属也只有一个现生种，为P.serrata，分布于北美洲西部，不是很常见，但在春末和夏季的一些地方可能数量相对丰富。 成虫有时发现于死的白冷杉枝条上，或旧原木和老树桩上，或下午在被真菌侵染过的朽木周围。

2023年11月5日 · Utilizing a genome-wide set of genes, we perform phylogenetic reconstruction and evolutionary dating of the P. serrata lineages. Obtained estimates reveal their relatively deep origin (approx. 6.5 Mya), comparable to the time of split between the human and chimpanzee lice Pediculus humanus and P. schaeffi .

2024年3月13日 · Compared with P. humanus, the P. serrata genomes are noticeably larger (139 vs. 111 Mbp) and encode a higher number of genes. Similar to P. humanus, they are reduced in sensory-related categories such as vision and olfaction. Utilizing genome-wide data, we perform phylogenetic reconstruction and evolutionary dating of the P. serrata lineages.

2012年7月24日 · The sequence data overwhelmingly support a sister group relationship between the archostematan beetle (P. serrata) and the polyphagan beetle (T. castaneum), indicating that Coleoptera represent a monophyletic group that does not include Strepsiptera.

biology and distribution of P. serrata. The objective of this work is to describe for the first time the patterns of spatial distribution of abundance of the pink speckled deep-sea shrimp, P. serrata in the Colombian Caribbean Sea. MATERIAL AND METHODS Data were collected by trawling in depths of 100 to 550 m at 24 h intervals in

2023年5月19日 · We recorded Pimelodella bockmanni and P. serrata for the first time for Colombia, based on specimens collected in tributaries from the main channel of the Amazonas River, in the so-called Trapecio Amazónico, in the southernmost region of this country.

The head of P. serrata and other adults of Archostemata is characterized by many derived features. Muscular features of Priacma, especially muscles of the labium and pharynx, differ strongly from what is found in other groups of Coleoptera.

To investigate head structures of Priacma serrata, an innovative technology—X-ray tomography—was applied for the first time in insect morphology and compared with other techniques. X-ray tomography, besides its application for medical purposes, has so far mainly been used to investigate bone and tooth
