Labrumoides vibrissa (Arthropoda: Pycnogonida), new callipallenid genus and new species from north Western Australia.

Specimens housed in the Australian Museum assigned to the genus Stylopallene are reviewed on the basis of their questionable geographic locations in the tropical waters of north Western Australia. Re-examination of those specimens shows only a superficial resemblance to the genus Stylopallene. The new genus Labrumoides gen.

Pycnogonids (Arthropoda, Pycnogonida) from the Southwest Indian Ridge.

This report addresses sixty-two deep-sea pycnogonid specimens collected by the Southwest Indian Ocean Seamounts Expedition, November 7 to December 21, 2011 on-board the British research vessel R.S.S.

Accurate estimates of age at maturity from the growth trajectories of fishes and other ectotherms.

Age at maturity (AAM) is a key life history trait that provides insight into ecology, evolution, and population dynamics. However, maturity data can be costly to collect or may not be available. Life history theory suggests that growth is biphasic for many organisms, with a change-point in growth occurring at maturity.

A reassessment of the pycnogonid genus Cheilopallene (Arthropoda, Callipallenidae) with description of a new species from Papua New Guinea.

The genus Cheilopallene is reviewed. Three species are assigned to species incertae sedis pending further analysis. Specimens from Lizard Island, Queensland, previously identified as C.

Impact of Compliance with a Care Bundle on Acute Kidney Injury Outcomes: A Prospective Observational Study.

Background: A recent report has highlighted suboptimal standards of care for acute kidney injury (AKI) patients in England. The objective of this study was to ascertain if improvement in basic standard of care by implementing a care bundle (CB) with interruptive alert improved outcomes in patients with AKI.

Methods: An AKI CB linked to electronic recognition of AKI, coupled with an interruptive alert, was introduced to improve basic care delivered to patients with AKI.

A revision of the callipallenid genus Pseudopallene Wilson, 1878 (Pycnogonida, Callipallenidae).

Analysis of three northern hemisphere Boreal-Arctic species of Pseudopallene has shown that those species are morphologically distinguishable from their congeners in Australian waters. The holotypes of Australian species Pseudopallene laevis, Pseudopallene ambigua and Pseudopallene harrisi are compared with each other and with additional material from southern Australia. Sixteen species of Pseudopallene are assigned to a new genus Meridionale.

Strong depth-related zonation of megabenthos on a rocky continental margin (∼700-4000 m) off southern Tasmania, Australia.

Assemblages of megabenthos are structured in seven depth-related zones between ∼700 and 4000 m on the rocky and topographically complex continental margin south of Tasmania, southeastern Australia. These patterns emerge from analysis of imagery and specimen collections taken from a suite of surveys using photographic and in situ sampling by epibenthic sleds, towed video cameras, an autonomous underwater vehicle and a remotely operated vehicle (ROV). Seamount peaks in shallow zones had relatively low biomass and low diversity assemblages, which may be in part natural and in part due to effects of bottom trawl fishing.

Spatiotemporal trends of mercury in walleye and largemouth bass from the Laurentian Great Lakes region.

The risk of mercury (Hg) exposure to humans and wildlife from fish consumption has driven extensive mercury analysis throughout the Great Lakes Region since the 1970s. This study compiled fish-Hg data from multiple sources in the region and assessed spatiotemporal trends of Hg concentrations in two representative top predator fish species. Walleye (Sander vitreus) and largemouth bass (Micropterus salmoides) were chosen for the trend analysis because they had more Hg records (63,872) than other fish species that had been sampled from waters throughout the region.

Quantitative trait locus mapping of genes under selection across multiple years and sites in Avena barbata: epistasis, pleiotropy, and genotype-by-environment interactions.

The genetic architecture of variation in evolutionary fitness determines the trajectory of adaptive change. We identified quantitative trait loci (QTL) affecting fitness in a mapping population of recombinant inbred lines (RILs) derived from a cross between moist- and dry- associated ecotypes of Avena barbata. We estimated fitness in 179 RILs in each of two natural environments in each of 4 years.
