Clonality contributes to the spread of Avrainvillea lacerata (Bryopsidales, Chlorophyta) in Hawai'i.

The relative rates of sexual versus asexual reproduction influence the partitioning of genetic diversity within and among populations. During range expansions, asexual reproduction often facilitates colonization and establishment. The arrival of the green alga Avrainvillea lacerata has caused shifts in habitat structure and community assemblages since its discovery in 1981 offshore of O'ahu, Hawai'i.

Resolving some of the earliest names for Corallina species (Corallinales, Rhodophyta) in the North Pacific by sequencing type specimens and describing the cryptic C. hakodatensis sp. nov. and C. parva sp. nov.

Partial rbcL sequences from type specimens of three of the earliest described Corallina species showed that C. arbuscula (type locality: Unalaska Island, Alaska, USA) and C. pilulifera (type locality: Okhotsk Sea, Russia) are synonymous, with C.

Phylogenomic resolution of the root of Panpulmonata, a hyperdiverse radiation of gastropods: new insight into the evolution of air breathing.

Transitions to terrestriality have been associated with major animal radiations including land snails and slugs in Stylommatophora (>20 000 described species), the most successful lineage of 'pulmonates' (a non-monophyletic assemblage of air-breathing gastropods). However, phylogenomic studies have failed to robustly resolve relationships among traditional pulmonates and affiliated marine lineages that comprise clade Panpulmonata (Mollusca, Gastropoda), especially two key taxa: Sacoglossa, a group including photosynthetic sea slugs, and Siphonarioidea, intertidal limpet-like snails with a non-contractile pneumostome (narrow opening to a vascularized pallial cavity). To clarify the evolutionary history of the panpulmonate radiation, we performed phylogenomic analyses on datasets of up to 1160 nuclear protein-coding genes for 110 gastropods, including 40 new transcriptomes for Sacoglossa and Siphonarioidea.

Factors Related to Sleep Disturbances for Informal Carers of Individuals With PD and Dyadic Relationship: A Rural Perspective.

This study examines factors related to sleep disturbances, and the dyadic sleep relationship, in a convenience sample of 29 persons with Parkinson disease (PD) and spouse carer dyads living in regional Queensland. Carers completed questionnaires on sleep, depression, anxiety, carer burden, and well-being. Regarding carers, 66% reported sleep disturbances related to nocturnally care demands.

Finding the Sweet Spot: Sub-Ambient Light Increases Fitness and Kleptoplast Survival in the Sea Slug cf. Gould, 1852.

Sacoglossans, or "sap-sucking" sea slugs, are primarily algivorous, with many taxa exhibiting kleptoplasty, the feeding and retaining of photosynthetically active chloroplasts from algae. The species complex exhibits some of the longest kleptoplast retention and survival times under starvation conditions, but the contributions of these kleptoplasts to their survival and overall fitness have been widely debated. In this study we assessed the effects of starvation and light on the fitness of cf.

Macroalgal germplasm banking for conservation, food security, and industry.

Ex situ seed banking was first conceptualized and implemented in the early 20th century to maintain and protect crop lines. Today, ex situ seed banking is important for the preservation of heirloom strains, biodiversity conservation and ecosystem restoration, and diverse research applications. However, these efforts primarily target microalgae and terrestrial plants.

Factors related to sleep disturbances for individuals with Parkinson's disease: a regional perspective.

Objectives: Sleep disturbances negatively impact the quality of life of patients with Parkinson's disease (PD). While persons living in regional areas are at higher risk of PD, PD is poorly managed in regional communities. This study examined factors associated with sleep problems in PD in a regional context.

Management of Sleep Disturbances in Parkinson's Disease Patients, Carers and the Patient and Carer Dyadic Relationship: A Scoping Review.

Objectives: Sleep disturbances are a debilitating non-motor symptom in Parkinson's disease (PD) and negatively impact patients, their carers and the patient-carer dyadic relationship. This review outlines the phenomenology, as well as factors associated with and treatment of sleep disturbances, in PD patients and their informal carers.

Methods: The following terms were used in four databases: Parkinson*, sleep* disturbance*, carer*, dyad*, intervention* and treatment*.

A new record of Avrainvillea cf. erecta (Berkeley) A. Gepp & E. S. Gepp (Bryopsidales, Chlorophyta) from urbanized estuaries in the Hawaiian Islands.

Background: A second species in the siphonous green algal genus was recently discovered off the island of O'ahu in the Main Hawaiian Islands. Specimens were collected from Honolulu Harbor, including its entrance channel, and near Ke'ehi Harbor. These locations are both in Mālama Bay on O'ahu's south shore in or adjacent to urbanized estuaries, respectively.

Updating Plakobranchus cf. ianthobapsus (Gastropoda, Sacoglossa) host use: Diverse algal-animal interactions revealed by NGS with implications for invasive species management.

Sacoglossa, the "sap sucking" sea slugs, are highly specialized herbivores and the only metazoans that exhibit kleptoplasty, the sequestration and retention of chloroplasts from algae. Plakobranchus is one of the most generalistic herbivores within this order, with as many as 12 reported "algal host" (i.e.

Uncovering unseen fungal diversity from plant DNA banks.

Throughout the world DNA banks are used as storage repositories for genetic diversity of organisms ranging from plants to insects to mammals. Designed to preserve the genetic information for organisms of interest, these banks also indirectly preserve organisms' associated microbiomes, including fungi associated with plant tissues. Studies of fungal biodiversity lag far behind those of macroorganisms, such as plants, and estimates of global fungal richness are still widely debated.

Molecular determination of kleptoplast origins from the sea slug Plakobranchus ocellatus (Sacoglossa, Gastropoda) reveals cryptic bryopsidalean (Chlorophyta) diversity in the Hawaiian Islands.

The sacoglossan sea slug species complex Plakobranchus ocellatus is a common algivore throughout the tropical Pacific, including the Hawaiian Islands. Plakobranchus ocellatus is kleptoplastic-it sequesters and retains algal chloroplasts-a characteristic that can be exploited to molecularly characterize diminutive bryopsidalean algae that are typically difficult to locate, collect, and identify. Previous DNA barcode analyses of both P.

Carers' perceptions of the impact of home telehealth monitoring on the provision of care and sustainability of use.

Aims: This paper aims to report carers' perceptions of the impact of home telehealth on the provision of care and the sustainability of home telehealth use.

Method: This paper is reporting on a sample of 15 carers who were involved in the telehealth arm of a larger controlled trial.

Results: Carers primarily believed that telehealth helped to provide better care.

Factors relating to home telehealth acceptance and usage compliance.

Aim: This paper investigates the acceptance of in-home telehealth by frail older adults and carers of the Transition Care Program (TCP), and evaluates telehealth acceptance as a predictor for usage compliance.

Method: A STRATIFIED RANDOM SAMPLE OF PARTICIPANTS WAS ALLOCATED TO ONE OF FIVE GROUPS: either a control group or to receive telehealth monitoring of their vital signs for a period of 12 or 24 weeks; with or without a medical alarm pendant.

Results: Before being trained in and using telehealth, the majority of participants and carers demonstrated acceptance of the technology by reporting that they perceived it would be "useful" and "easy to use.

Factors affecting provision of successful monitoring in home Telehealth.

Aim: To investigate acceptance and usage issues in relation to Telehealth products as used by frail older clients of the Transition Care Program and their carers.

Method: The study design was a quasi-randomised controlled clinical trial. A stratified random sample of participants was allocated to one of five groups using a random number table.
