Temperate Intertidal Ecosystems are Functionally Richer but More Vulnerable to Loss Than Tropical Ecosystems.

Gastropods are major contributors to a range of key ecosystem services on intertidal rock platforms, supporting trophic structure in both terrestrial and marine contexts and manipulating habitat complexity. However, the functional structure of these assemblages is rarely examined across broad spatial scales. Here, we describe patterns in gastropod functional diversity, redundancy and vulnerability to functional loss across a latitudinal gradient following the west coast of Australia (18° S-34° S).

'People with intellectual disabilities living in the communities is bad enough let alone…having sex': Exploring societal influence on social care workers' attitudes, beliefs and behaviours towards support for personal and sexual relationship needs.

Background: Services have a duty to uphold the personal and sexual relationship (P&SR) rights of adults with intellectual disability. However, little is known about how social care workers' (SCWs) perceptions of public views of intellectual disability and sexuality might affect their attitudes, believes and behaviours towards supporting P&SR needs. This exploratory study addresses this gap in knowledge.

Mystery pufferfish create elaborate circular nests at mesophotic depths in Australia.

In 2011, the enigma of "mystery circles," small but complex underwater structures first observed by divers from southern Japan in 1995, was solved when a new species of pufferfish, white-spotted pufferfish (Torquigener albomaculosus Matsuura 2014), was identified as the responsible agent. To date these circles have been described only from Japan, where they are formed on a sandy seafloor in water depths less than 30 m. A survey of oil field infrastructure on the North West Shelf of Western Australia in 2018 using a remotely operated vehicle and hybrid autonomous underwater vehicle (HAUV) recorded a high-resolution video and bathymetric data of 21 circular formations with similar features to those described in Japan.

Temporal Patterns in the Abundance of a Critically Endangered Marsupial Relates to Disturbance by Roads and Agriculture.

The aim of this study was to investigate how landscape disturbance associated with roads, agriculture and forestry influenced temporal patterns in woylie (Bettongia penicillata) abundance before, during and after periods of rapid population change. Data were collected from an area of approximately 140,000 ha of forest within the Upper Warren region in south-western Australia. Woylie abundance was measured using cage trapping at 22 grid and five transect locations with varying degrees of landscape disturbance between 1994 and 2012.

Treating rheumatoid arthritis to target: a Canadian patient survey.

Background: Recently, many countries, including Canada, evaluated rheumatologists' acceptance and agreement with a set of 10 Treat to Target (T2T) recommendations for rheumatoid arthritis (RA), developed by an international task force. In this study, the Canadian T2T steering committee evaluated how Canadian patients with RA perceive these recommendations.

Objectives: The objectives of this study were to assess the current state of RA management in Canada from a patient perspective and to assess whether and to what extent Canadians with RA agree with each of the 10 T2T recommendations and to compare the results with a previous survey completed by physicians.

More than bindin divergence: reproductive isolation between sympatric subspecies of a sea urchin by asynchronous spawning.

The evolution of reproductive barriers is crucial to the process of speciation. In the Echinoidea, studies have focused on divergence in the gamete recognition protein, bindin, as the primary isolating mechanism among species. As such, the capacity of alternate mechanisms to be effective reproductive barriers and the phylogenetic context in which they arise is unclear.

Readiness to manage arthritis: a pilot study using a stages-of-change measure for arthritis rehabilitation.

The purpose of this pilot study was to evaluate the Readiness to Manage Arthritis Questionnaire (RMAQ), a new multibehavior measure of readiness for change in arthritis management. Data were obtained from 46 patients with chronic inflammatory arthritis admitted for intensive treatment. Test-retest reliability, correlations with clinical variables and theoretically related constructs, and responsiveness to change were assessed.
