The Relationship

Abstract Dorids are one of the largest nudibranch groups, encompassing more than 2000 species. One of the crucial problems with tracing the evolution of dorids is the relationship between cryptobranch dorids (gill cavity present) and phanerobranch dorids (gill cavity absent). Integrative morphological and molecular studies of the enigmatic Japanese dorid species of the cryptobranch genus Cadlina, C. japonica and ‘C.’ sagamiensis, which were collected by the Emperor of Japan (Shōwa era), are presented here for the first time. It is shown that while C. japonica does belong to the Cadlina clade, another Japanese species ‘C.’ sagamiensis is not part of the cryptobranch dorids of the family Cadlinidae, but is related to both the phanerobranch dorid family, Hexabranchidae, and to the cryptobranch family Cadlinellidae stat. nov. A new genus, Showajidaia gen. nov., and new family, Showajidaiidae fam. nov., are proposed for ‘C.’ sagamiensis, and four new species of the genus Cadlina are described based on a dorid-wide molecular phylogenetic analysis, which is the first substantial update of the dorid family system since 2010. Integration of phylogenetic data with an ontogenetic model of dorid evolution suggests that cryptobranch organization can be most reliably assessed as the ancestral state for the majority of dorids.

Hyphodontia sensu lato, belonging to Hymenochaetales, accommodates corticioid wood-inhabiting basidiomycetous fungi with resupinate basidiocarps and diverse hymenophoral characters. Species diversity of Hyphodontia sensu lato has been extensively explored worldwide, but in previous studies the six accepted genera in Hyphodontia sensu lato, viz. Fasciodontia, Hastodontia, Hyphodontia, Kneiffiella, Lyomyces and Xylodon were not all strongly supported from a phylogenetic perspective. Moreover, the relationships among these six genera in Hyphodontia sensu lato and other lineages within Hymenochaetales are not clear. In this study, we performed comprehensive phylogenetic analyses on the basis of multiple loci. For the first time, the independence of each of the six genera receives strong phylogenetic support. The six genera are separated in four clades within Hymenochaetales: Fasciodontia, Lyomyces and Xylodon are accepted as members of a previously known family Schizoporaceae, Kneiffiella and Hyphodontia are, respectively, placed in two monotypic families, viz. a previous name Chaetoporellaceae and a newly introduced name Hyphodontiaceae, and Hastodontia is considered to be a genus with an uncertain taxonomic position at the family rank within Hymenochaetales. The three families emerged between 61.51 and 195.87 million years ago. Compared to other families in the Hymenochaetales, these ages are more or less similar to those of Coltriciaceae, Hymenochaetaceae and Oxyporaceae, but much older than those of the two families Neoantrodiellaceae and Nigrofomitaceae. In regard to species, two, one, three and 10 species are newly described from Hyphodontia, Kneiffiella, Lyomyces and Xylodon, respectively. The taxonomic status of additional 30 species names from these four genera is briefly discussed; an epitype is designated for X. australis. The resupinate habit and poroid hymenophoral configuration were evaluated as the ancestral state of basidiocarps within Hymenochaetales. The resupinate habit mainly remains, while the hymenophoral configuration mainly evolves to the grandinioid-odontioid state and also back to the poroid state at the family level. Generally, a taxonomic framework for Hymenochaetales with an emphasis on members belonging to Hyphodontia sensu lato is constructed, and trait evolution of basidiocarps within Hymenochaetales is revealed accordingly.

Purpose: To determine the relationship between family coping and resources and family adjustment and parental stress in the acute phase of the NICU experience.Design: Correlational study based on the Resiliency Model of Family Stress, Adjustment, and Adaptation. Main study instruments included the State Anxiety scale of the State-Trait Anxiety Inventory, the Family Inventory of Resources for Management, the Family Crisis Oriented Personal Evaluation Scales, and the General Functioning subscale of the McMaster Family Assessment Device.Sample: Data collected from 124 mother and father pairs within two to four days of their infant’s admission to the NICU.Main Outcome Variables: Family adjustment and parental stress.Results: Adequate resources were more strongly related to positive adjustment and decreased stress than were either coping or being a first-time parent. The relationships among the variables were generally the same for both parents. Mothers utilized more coping strategies than did fathers.Practice Recommendations: Families with limited resources should be identified early to facilitate their adjustment to the NICU.

Purpose The purpose of this study was to understand how the family system plays a role in knowledge sharing (KS) within family firms. The authors argue that the family’s influence can occur through two routes. An external route in which the family affects the culture of the organization and through an internal route in which family leadership within the firm affects the practices and behaviors within the business. Design/methodology/approach Data for this project came from the survey responses of 93 Spanish family firms. Findings The findings expand previous understanding about KS in family firms by outlining the two routes through which the family can have positive effect on KS within family firms. Results show that family system characteristics (i.e. next-generation commitment, family trust and intergenerational relationships) affect KS through their impact on the participative culture of a family firm. Additionally, when a family has been in control of the business for more generations, they place higher importance on family legacy and continuity, which is likely to strengthen the relationship between participative culture and KS in family firms. Originality/value Given the important role that the family system plays within the family business, this paper explored how family characteristics can influence KS in family firms. The authors contribute to the literature by highlighting the importance that the owning family can have in creating an environment that can facilitate KS in family firms.

The laniatorean family Phalangodidae has been largely reduced to a core of Holarctic species; however, many taxa were never formally transferred to other families. We examined a group of harvestmen related to Beloniscus Thorell, 1891, from South-east Asia and determined the nature of the relationships of the ‘Beloniscus-like harvestmen’, herein described as the new family Beloniscidae, fam. nov., in the broad context of Laniatores. Based on a molecular phylogenetic analysis of a broad representative laniatorean Sanger-sequences dataset we found support for our taxonomic hypotheses that (1) inclusion of Beloniscidae, fam. nov. in Phalangodidae would render the family non-monophyletic, and (2) Beloniscidae, fam. nov. represents a lineage that is morphologically and genetically distinct from all other known laniatorean families. The new family Beloniscidae is endemic to South-east Asia and comprises 37 species in two new subfamilies: Beloniscinae, subfam. nov. and Buparinae, subfam. nov. Beloniscinae includes the genera Beloniscellus Roewer, 1931, Beloniscops Roewer, 1949, Belonisculus Roewer, 1923, Beloniscus (type genus) and Kendengus Roewer, 1949. Buparinae includes the genera Buparellus Roewer, 1949, Bupares Thorell, 1889 (type genus) and Buparomma Roewer, 1949. Members of Beloniscidae are relatively homogeneous in their external morphology, but are recognised by well marked genitalic features. Male genitalia are described for exemplar species, and the morphology is compared with that of Epedanidae. Names are given to two new genitalic structures: sella curulis and pseudocalyx. http://zoobank.org/urn:lsid:zoobank.org:act:540BCE49-6F2E-4372-BFD4-D3C6068F045D http://zoobank.org/urn:lsid:zoobank.org:act:FE8B011B-AA6D-4E6C-A321-123542A0563F http://zoobank.org/urn:lsid:zoobank.org:act:E4A559CD-170A-40F2-924A-541C22974344

Among Opiliones, Afrotropical lineages constitute some of the least studied groups in comparison with those endemic to other biogeographic provinces. Based upon morphological evidence, we erect Pyramidopidae, fam. nov. to distinguish a group of Laniatores from the family Phalangodidae. We review evidence from recent molecular phylogenetic studies that corroborate the independence of Pyramidopidae, fam. nov. from previously described families and support its sister relationship to another largely Afrotropical group, the family Assamiidae. The monotypic genus Maiorerus Rambla, 1993 is transferred to Pyramidopidae, fam. nov. The new family comprises 12 genera geographically restricted to Africa and the adjacent Canary Islands. Interfamilial relationships of the derived Laniatores are discussed in the context of gross and genitalic morphology.

Molecular Phylogenetic Data

The Australasian spiny trapdoor spiders of the family Idiopidae (subfamily Arbanitinae) are revised at the generic level, using a multi-locus molecular phylogenetic foundation and comprehensive sampling of all known lineages. We propose a new family- and genus-group classification for the monophyletic Australasian fauna, and recognise 10 genera in four tribes. The Arbanitini Simon includes Arbanitis L. Koch, 1874 (61 species), Blakistonia Hogg, 1902 (one species) and Cantuaria Hogg, 1902 (43 species). The Aganippini Simon includes Bungulla Rix, Main, Raven & Harvey, gen. nov. (two species), Eucanippe Rix, Main, Raven & Harvey, gen. nov. (one species), Eucyrtops Pocock, 1897 (two species), Gaius Rainbow, 1914 (one species) and Idiosoma Ausserer, 1871 (14 species). The Cataxiini Rainbow and Euoplini Rainbow include just Cataxia Rainbow, 1914 (11 species) and Euoplos Rainbow, 1914 (12 species), respectively. Two distinctive new genera of Aganippini are described from Western Australia, and several previously valid genera are recognised as junior synonyms of existing genus-group names, including Misgolas Karsch, 1878 (= Arbanitis; new synonymy), Aganippe O. P.-Cambridge, 1877 (= Idiosoma; new synonymy) and Anidiops Pocock, 1897 (= Idiosoma; new synonymy). Gaius stat. rev. is further removed from synonymy of Anidiops. Other previously hypothesised generic synonyms are supported by both morphology and molecular phylogenetic data from 12 genes, including the synonymy of Neohomogona Main, 1985 and Homogona Rainbow, 1914 with Cataxia, and the synonymy of Albaniana Rainbow & Pulleine, 1918, Armadalia Rainbow & Pulleine, 1918, Bancroftiana Rainbow & Pulleine, 1918 and Tambouriniana Rainbow & Pulleine, 1918 with Euoplos. At the species level, the identifications of Eucy. latior (O. P.-Cambridge, 1877) and I. manstridgei (Pocock, 1897) are clarified, and three new species are described: Bungulla bertmaini Rix, Main, Raven & Harvey, sp. nov., Eucanippe bifida Rix, Main, Raven & Harvey, sp. nov. and Idiosoma galeosomoides Rix, Main, Raven & Harvey, sp. nov., the latter remarkable for its phragmotic abdominal morphology. The Tasmanian species Mygale annulipes C. L. Koch, 1842 is here transferred to the genus Stanwellia Rainbow & Pulleine, 1918 (family Nemesiidae), comb. nov., Arbanitis mestoni Hickman, 1928 is transferred to Cantuaria, comb. nov. and Idiosoma hirsutum Main, 1952 is synonymised with I. sigillatum (O. P.-Cambridge, 1870), new synonymy. In addition to the morphological synopses and an illustrated key to genera, molecular diagnoses are presented for all nominal taxa, along with live habitus and burrow images to assist in field identification. The Australasian idiopid fauna is highly diverse, with numerous new species known from all genera. As a result, this study provides a taxonomic and nomenclatural foundation for future species-level analyses, and a single reference point for the monographic documentation of a remarkable fauna. http://zoobank.org/?lsid=urn:lsid:zoobank.org:pub:BACE065D-1EF9-40C6-9134-AADC9235FAD8

Based on our molecular phylogenetic analysis of haplolepideous mosses with concatenated sequences of chloroplast rps4 and rbcL genes, a new family Timmiellaceae is erected to accommodate the genera Timmiella and Luisierella, both of which have been formerly included in the family Pottiaceae.  The family Timmiellaceae is resolved as a second-branching clade together with Distichium (Distichiaceae) within the Dicranidae (haplolepideous moss) lineages and phylogenetically distinct from the Pottiaceae.  Reassessment of morphological characters suggests that a combination of the characters: 1) adaxially bulging and abaxially flat leaf surfaces, 2) sinistrorse or straight peristomes, when present, and 3) sinistrorsely arranged operculum cells is unique to Timmiellaceae and discriminates it from other haplolepideous moss families.

The article presents the results of an empirical study on changes in the system of a woman's relations after a divorce, which can be manifested both in a woman's self-attitude and in her attitude towards a man; divorced women, compared to married women, have a higher percentage of non-optimal self-attitude and negative attitude towards men, divorced women with and without a child after a divorce have got differences not only in the percentage of non-optimal self-attitude and negative attitude towards men, but also in the connection between them. We have conducted our research and received the following results. Divorced women, as compared to married women, have a higher percentage of suboptimal self-attitude and negative attitude towards men. The assumption that divorced women with a child after a divorce have got a higher percentage of non-optimal self-attitude and negative attitude towards a man than women without a child after a divorce was not confirmed, while the assumption of a less close connection of self-attitude and attitude towards a man was confirmed. For the first time, an empirical study was conducted that allows us to study not only the features of self-attitude and attitude to a man in women after divorce, but also the relationship between them. The results obtained in the study can be used by psychologists working with women who are divorced. The development of an optimal self-attitude in such women will not only increase adaptive capabilities, but also contribute to a change in attitude towards a man, which ultimately can be a positive factor in creating a new family.

Background: Despite much attention in the clinical literature, research on alexithymia in the treatment setting has only recently gained traction. While several reports indicate limited benefit from therapy amongst patients with high alexithymia, this seems to be less so in the context of group therapy. This study considers a specific aspect of the group therapy process - family re-enactment - infacilitating improvement in overall quality of life for patients with high levels of alexithymia.Subjects and methods: Family re-enactment was examined as a potential mediator of the relationship between alexithymia and change in quality of life among 50 patients who completed treatment in an intensive, integrative group therapy programme. Patients completed three self-report measures: Toronto Alexithymia Scale-20 (baseline), Quality of Life Inventory (baseline, post-therapy), and Therapeutic Factors Inventory-Short Form (week 8). Regression with mediation analysis was employed using the change scorefor the QOLI as the dependent variable, alexithymia scores as the independent variable, and the family re-enactment score as the mediator; baseline quality of life was included in the model as a control variable.Results: Family re-enactment emerged as a significant mediator of the relationship between alexithymia and treatment outcome, implicating it as a contributing mechanism of change for alexithymic patients who participate in group therapy.Conclusion: Patients with higher levels of alexithymia (in particular, difficulty identifying and describing feelings) were more likely to positively endorse aspects of family re-enactment during group therapy, which in turn were significantly associated with greater improvement in patients’ overall quality of life.

Mygalomorph spiders of the family Theraphosidae, known to the broader public as tarantulas, are among the most recognizable arachnids on earth due to their large size and widespread distribution. Their use of urticating setae is a notable adaptation that has evolved exclusively in certain New World theraphosids. Thus far, the evolutionary history of Theraphosidae remains poorly understood; theraphosid systematics still largely relies on morphological datasets, which suffer from high degrees of homoplasy, and traditional targeted sequencing of preselected genes failed to provide strong support for supra-generic clades (i.e. particularly those broader than subfamilies). In this study, we provide the first robust phylogenetic hypothesis of theraphosid evolution inferred from transcriptome data. A core ortholog approach was used to generate a phylogeny from 2460 orthologous genes across 25 theraphosid genera, representing all of the major theraphosid subfamilies, except Selenogyrinae. For the first time our phylogeny recovers a monophyletic group that comprises the vast majority of New World theraphosid subfamilies including Aviculariinae and Theraphosinae. Concurrently, we provide additional evidence for the integrity of questionable subfamilies, such as Poecilotheriinae and Psalmopoeinae, and support the non-monophyly of Ischnocolinae. The deeper relationships between almost all subfamilies are confidently inferred for the first time. We also used our phylogeny in tandem with published morphological data to perform ancestral state analyses on urticating setae. This revealed that the evolution of this important defensive trait might be explained by three equally parsimonious scenarios.
