Anophryocephalus inuitorum sp.nov. and A. arcticensis sp.nov. are described from ringed seals (Phoca hispidu hispida) in the eastern Canadian Arctic; the latter species is also reported from harp seals (Phoca groenlandicu) in the Gulf of St. Lawrence. Anophryocephalus inuitorurn is most similar to A. skrjabini, but can be distinguished by fewer testes (14-27) and smaller dimensions of the strob...
The study of the morphology of stone artifacts and their spatio-temporal changes in form has gained great importance in Paleolithic archaeology today. This growing attention is due to the prevalent use of advanced multivariate statistical methods in archaeology, the growing connection between archaeologists and the specialists of life sciences (e.g., animal biosystematics) and programming langu...
Evolution theory predicts that the ancestry of organisms can be traced down a hypothetical evolutionary tree and eventually back to the first living cell. Creation theory postulates that ancestry can be traced back only a limited distance to a starting organism of that type. Instead of a “tree” the creation model has a “forest” of unrelated organisms with vast genetic potential. I hypothesize t...

In December 2006, Rift Valley fever (RVF) was diagnosed in humans in Garissa Hospital, Kenya and an outbreak reported affecting 11 districts. Entomologic surveillance was performed in four districts to determine the epidemic/epizootic vectors of RVF virus (RVFV). Approximately 297,000 mosquitoes were collected, 164,626 identified to species, 72,058 sorted into 3,003 pools and tested for RVFV by...
We evaluated stock structure and demographic (population) history of red snapper (Lutjanus campechanus) in the northern Gulf of Mexico (Gulf) via analysis of mitochondrial (mt)DNA sequences from 360 individuals sampled from four cohorts (year classes) at three localities across the northern Gulf. Exact tests of genetic homogeneity and analysis of molecular variance both among cohorts within loc...
The establishment of high-throughput sequencing, together with bioinformatic processing tools—the genomics revolution—has impacted biology during the last decade by resolving long-standing questions in phylogenetics (Abalde et al., 2019; Rochette 2014; Struck 2011), speciation and adaptation (Birkeland 2020; Ravinet 2017, 2018; Weber 2019), opening new venues research such as genome-wide struct...
