Larval ground plan of Platynectes Régimbart, 1879 reconsidered: description of the larvae of three species with phylogenetic considerations (Coleoptera: Adephaga, Dytiscidae).

In this contribution we describe and illustrate for the first time the larvae of three species of Platynectes Régimbart, 1879 (P. agallithoplotes Gustafson, Short & Miller, 2016, P. bakewelli (Clark, 1863), and P.

An outlook on larval morphology of Copelatinae diving beetles with phylogenetic considerations (Coleoptera: Adephaga, Dytiscidae).

The larvae of 12 species of Copelatinae, Copelatus alternatus Sharp, 1882, C. caelatipennis princeps Young, 1963, C. glyphicus (Say, 1823), C.

Intermediate to long term results of stemless metaphyseal reverse shoulder arthroplasty: A five to nine year follow-up.

Background: Shoulder arthroplasty incidence is increasing as is the volume of revision surgeries. Revision surgery is easier if humeral bone stock is preserved with minimal bone defects and osteolysis. This has led to an increased focus on the development of various short stemmed and stemless implants which provides stable fixation whilst preserving humeral bone stock.

The "minute diving beetles" of southern Australia - taxonomic revision of Watts, 1978, with description of six new species (Coleoptera, Dytiscidae, Bidessini).

Morphology and mitochondrial DNA sequence data are used to reassess the taxonomy of Australian diving beetles previously assigned to the genera Guignot, 1939 and Watts, 1978. was described as a monotypic genus for Watts, 1978. The genus is significantly extended here.

Dealing with a hairy beast-larval morphology and chaetotaxy of the Australian endemic diving beetle genus (Coleoptera, Dytiscidae, Cybistrini).

In this contribution, the larval morphology of Sharp, 1882 was studied, an Australian endemic genus in the diving beetle tribe Cybistrini. All instars of the only two species included in the genus ( Sharp, 1882 and Sharp, 1882) are described and illustrated with the exception of the third instar of . Detailed morphometric and primary chaetotaxic analyses were performed to discover useful characters for generic diagnosis and species distinction.

Stakeholder involvement in systematic reviews: a scoping review.

Background: There is increasing recognition that it is good practice to involve stakeholders (meaning patients, the public, health professionals and others) in systematic reviews, but limited evidence about how best to do this. We aimed to document the evidence-base relating to stakeholder involvement in systematic reviews and to use this evidence to describe how stakeholders have been involved in systematic reviews.

Methods: We carried out a scoping review, following a published protocol.

Review of Australian Illiger, Ora Clark and Pic Coleoptera: Scirtidae) including descriptions of new species, new groups and a multi-gene molecular phylogeny of Australian and non-Australian species.

The phylogenetic relationships of 26 Australian species of Scirtes Illiger, Ora Clark and Exochomoscirtes Pic (Scirtidae) were investigated using adult morphology, particularly male and female genitalia, larval morphology and molecular data from the mitochondrial cytochrome c oxidase subunit I (COI) gene and the nuclear genes elongation factor 1-alpha (EF1- a) and topoisomerase I (TOP1). Four species of Scirtes and one of Ora from Europe, Southeast Asia and Japan were included. The genus Scirtes is shown to be paraphyletic with respect to the genera Ora and Exochomoscirtes.

Stakeholder involvement in systematic reviews: a protocol for a systematic review of methods, outcomes and effects.

Plain English Summary: Researchers are expected to actively involve stakeholders (including patients, the public, health professionals, and others) in their research. Although researchers increasingly recognise that this is good practice, there is limited practical guidance about how to involve stakeholders. Systematic reviews are a research method in which international literature is brought together, using carefully designed and rigorous methods to answer a specified question about healthcare.

Milled cereal straw accelerates earthworm () growth more than selected organic amendments.

Earthworms benefit agriculture by providing several ecosystem services. Therefore, strategies to increase earthworm abundance and activity in agricultural soils should be identified, and encouraged. earthworms primarily feed on organic inputs to soils but it is not known which organic amendments are the most effective for increasing earthworm populations.

Description of a new Watts, 1985 from northern Queensland, Australia (Coleoptera: Dytiscidae, Hydroporinae).

Tiporus queenslandicus sp. n. is described from NE Queensland.

Notes on the Australian Anacaenini (Coleoptera: Hydrophilidae): description of male of Phelea breviceps Hansen and unravelling the identity of Crenitis neogallica Gentili.

The holotype and additional specimens of the Tasmanian endemic Phelea breviceps Hansen, 1999, and the holotype of Crenitis neogallica Gentili, 1996 were examined in order to explore their generic and tribal placement. The morphology of Phelea is illustrated in detail, its male genitalia are described for the first time, and it is confirmed as a member of Anacaenini, sharing numerous characters with Crenitis Bedel, 1881 and the New Zealand endemic Horelophus walkeri Orchymont, 1913. Crenitis neogallica is removed from Anacaenini and transferred to the rygmodine genus Pseudohydrobius Blackburn, 1898 (as Pseudohydrobius neogallicus (Gentili, 1996) comb.

Unveiling the diversification dynamics of Australasian predaceous diving beetles in the Cenozoic.

During the Cenozoic, Australia experienced major climatic shifts that have had dramatic ecological consequences for the modern biota. Mesic tropical ecosystems were progressively restricted to the coasts and replaced by arid-adapted floral and faunal communities. Whilst the role of aridification has been investigated in a wide range of terrestrial lineages, the response of freshwater clades remains poorly investigated.

A novel grass hybrid to reduce flood generation in temperate regions.

We report on the evaluation of a novel grass hybrid that provides efficient forage production and could help mitigate flooding. Perennial ryegrass (Lolium perenne) is the grass species of choice for most farmers, but lacks resilience against extremes of climate. We hybridised L.

Evolution of blind beetles in isolated aquifers: a test of alternative modes of speciation.

Evidence is growing that not only allopatric but also sympatric speciation can be important in the evolution of species. Sympatric speciation has most convincingly been demonstrated in laboratory experiments with bacteria, but field-based evidence is limited to a few cases. The recently discovered plethora of subterranean diving beetle species in isolated aquifers in the arid interior of Australia offers a unique opportunity to evaluate alternative modes of speciation.

Applying skills and knowledge: Principle Of Nursing Practice F.

This is the seventh article in a nine-part series describing the Principles of Nursing Practice developed by the Royal College of Nursing (RCN) in collaboration with patient and service organisations, the Department of Health, the Nursing and Midwifery Council, nurses and other healthcare professionals. The article discusses Principle F, the application of skills and knowledge to person-centred nursing care.

Principles of nursing practice: development and implementation.

This article, the first in a nine-part series, describes the development of the recent Principles of Nursing Practice initiative. It provides an overview of the Principles, the objectives that informed them and the challenges experienced in their development.

Assessment of acute pain in children: development of evidence-based guidelines.

Aim: Detecting children's pain in a healthcare setting can be improved by facilitating pain expression in ways that are appropriate to the child's cognitive development and that can be recognised by their carers. To ensure up-to-date guidance on assessing pain in children, the Royal College of Nursing undertook an evidence-based update of pain assessment guidelines, initially published in 2000.

Methods: Following systematic review of the psychometric testing literature, a two-stage critical appraisal process was developed to derive a list of robust tools that could be recommended for use in a variety of settings to assess the intensity of a child's acute pain.

Root water potential integrates discrete soil physical properties to influence ABA signalling during partial rootzone drying.

To investigate the influence of different growing substrates (two mineral, two organic) on root xylem ABA concentration ([ABA](root)) and the contribution of the drying root system to total sap flow during partial rootzone drying (PRD), sunflower (Helianthus annuus L.) shoots were grafted onto the root systems of two plants grown in separate pots. Sap flow through each hypocotyl was measured below the graft union when one pot ('wet') was watered and other ('dry') was not.

Non-edible plant oils as new sources for biodiesel production.

Due to the concern on the availability of recoverable fossil fuel reserves and the environmental problems caused by the use those fossil fuels, considerable attention has been given to biodiesel production as an alternative to petrodiesel. However, as the biodiesel is produced from vegetable oils and animal fats, there are concerns that biodiesel feedstock may compete with food supply in the long-term. Hence, the recent focus is to find oil bearing plants that produce non-edible oils as the feedstock for biodiesel production.

Meeting report: risk assessment of tamiflu use under pandemic conditions.

On 3 October 2007, 40 participants with diverse expertise attended the workshop Tamiflu and the Environment: Implications of Use under Pandemic Conditions to assess the potential human health impact and environmental hazards associated with use of Tamiflu during an influenza pandemic. Based on the identification and risk-ranking of knowledge gaps, the consensus was that oseltamivir ethylester-phosphate (OE-P) and oseltamivir carboxylate (OC) were unlikely to pose an ecotoxicologic hazard to freshwater organisms. OC in river water might hasten the generation of OC-resistance in wildfowl, but this possibility seems less likely than the potential disruption that could be posed by OC and other pharmaceuticals to the operation of sewage treatment plants.

Chronic aquatic environmental risks from exposure to human pharmaceuticals.

This paper reviews current information on the chronic aquatic toxicity of human pharmaceuticals and how it should be measured. Chronic toxicity tests with Cyanobacteria are likely to be sensitive surrogates for both algae and other unicellular organisms, although possibly not for higher plants. In contrast, there is little evidence of a general need to perform chronic aquatic invertebrate tests for all human pharmaceuticals, although further acute-to-chronic ratio data are required for the main therapeutic classes and modes of action of pharmaceuticals before this issue can be fully resolved.
