Arrupakiyoshiensis Tsukamoto & Shimano, sp. n. is described from a limestone cave, Kagekiyo-ana, in Akiyoshi-dai, one of the largest karst regions in Japan, Yamaguchi prefecture. It is distinguishable from 14 valid named congeners by some unique characteristics including entire areolation on the cephalic pleurite, elongation of distal part of female gonopod, and a tubercle on forcipular segment II. In addition, the 18S rRNA gene sequences of A.akiyoshiensis Tsukamoto & Shimano, sp. n. and A.ishiianus, one of the most morphologically similar species, differed by four bp out of 1821 bp. The fact that only troglobionts and troglophilic species are found in the collection site suggests that this new species might be a cave-dweller.

AbstractThe history of a trait within a lineage may influence its future evolutionary trajectory, but macroevolutionary theory of this process is not well developed. For example, consider the simple binary trait of living in cave versus surface habitat. The longer a species has been cave-dwelling, the more may accumulated loss of vision, pigmentation, and defense restrict future adaptation if the species encounters the surface environment. However, the Markov model of discrete trait evolution that is widely adopted in phylogenetics does not allow the rate of cave-to-surface transition to decrease with longer duration as a cave-dweller. Here, we describe three models of evolution that remove this ‘memory-less’ constraint, using a renewal process to generalize beyond the typical Poisson process of discrete trait macroevolution. We then show how the two-state renewal process can be used for inference, and we investigate the potential of phylogenetic comparative data to reveal different influences of trait duration, or ‘memory’ in trait evolution. We hope that such approaches may open new avenues for modeling trait evolution and for broad comparative tests of hypotheses that some traits become entrenched.

This paper describes a new genus of Nesticidae based on morphology of the genital characters and supported by molecular data. The new genus, Domitius n. gen., includes a group of seven cave-dweller species spread along western European peninsulas (Iberian and Italian). Molecular phylogenetic analysis shows that these species constitute an independent and highly supported evolutionary lineage being the sister group to Kryptonesticus Pavlek & Ribera, 2017, Nesticus Thorell, 1869 and Carpathonesticus Lehtinen & Saaristo, 1980 genera. As a result, seven new combinations are here proposed: Domitius baeticus (López-Pancorbo & Ribera, 2011) n. comb., Domitius murgis (Ribera & De Mas, 2003) n. comb., Domitius lusitanicus (Fage, 1931) n. comb., Domitius luquei (Ribera & Guerao, 1995) n. comb., Domitius sbordonii (Brignoli, 1979) n. comb., Domitius menozzii (Caporiacco, 1934) n. comb., Domitius speluncarum (Pavesi, 1873) n. comb.

Even in in health healthcare and health information technology change will not vanish or disperse. Technology, civilization, and creative thought will drive this force increasingly forward. Health care managers will continue being judged on their ability to efficiently and effectively manage (Patton & James, 2000). The pace of change has significantly increased since the days of the cave dweller who walked the earth until the “technology convergence” of using the ox and horse as tools. This article is to investigate the background, controversies, and problems surrounding Health Information Technology and change, and will include an overview of current changes. This will be coupled with solutions and recommendations, further research, and conclusion.
