Contrary to global production, most fibers floating in the ocean are not synthetic but natural of animal or plant origin.
While macroplastics have been washing up on Southern Ocean islands for decades and microplastics found in seabirds from the region since 1960, there are still relatively few quantitative data amount of plastic pollution, especially with regard to floating plastics, at high southern latitudes. We present a baseline estimate abundance plastics around survey macro-, meso- microplastic pollution conducted during Antarctic Circumnavigation Expedition 2016/17. A total 40 net trawls 626 h...
Abstract Antarctica is one of Earth's most untouched, inhospitable, and poorly known regions. Although knowledge its biodiversity has increased over recent decades, a diverse, wide‐ranging, spatially explicit compilation the that inhabits Antarctica's permanently ice‐free areas unavailable. This absence hinders both Antarctic research integration in global biodiversity–related studies. Fundamental applied on patterns, ecological structure function, options for conservation are reliant...
Many bacterial pathogens produce diffusible signal factor (DSF)-type quorum sensing (QS) signals in modulation of virulence and biofilm formation. Previous work on Xanthomonas campestris showed that the RpfC/RpfG two-component system is involved responding to DSF signals, but little known other microorganisms. Here we show Burkholderia cenocepacia DSF-family cis -2-dodecenoic acid (BDSF) negatively controls intracellular cyclic dimeric guanosine monophosphate (c-di-GMP) level through a...
Abstract Cyhalothrin is a common environmental pollutant which poses increased risks to non-target organisms including human beings. This study reported for the first time newly isolated strain, Bacillus thuringiensis ZS-19 completely degraded cyhalothrin in minimal medium within 72 h. The bacterium transformed by cleavage of both ester linkage and diaryl bond yield six intermediate products. Moreover, novel degradation pathway strain was proposed on basis identified metabolites. In addition...
Abstract The Antarctic Conservation Biogeographic Regions ( ACBR s), originally proposed in 2012, are now established as an important tool science, conservation, management and policy. Here, we provide a revised version of the s, reflecting updates underlying spatial layers, together with results new analyses justifying inclusion 16th bioregion. This updated covers all ice‐free areas Antarctica is publicly available through Australian Data Centre. In light interest s across variety research...
Antarctic biodiversity faces an unknown future with a changing climate. Most terrestrial biota is restricted to limited patches of ice-free land in sea ice, where they are adapted the continent's extreme cold and wind exploit microhabitats suitable conditions. As temperatures rise, areas predicted expand, more rapidly some than others. There high uncertainty as how species' distributions, physiology, abundance, survivorship will be affected their habitats transform. Here we use current...
Dickeya zeae is the causal agent of rice foot rot disease, but its mechanism infection remains largely unknown. In this study, we identified and characterized a novel gene designated as zmsA. The encodes large protein 2,346 amino acids in length, which consists multidomains arranged order N-terminus, β-ketoacyl synthase, acyl transferase, carrier protein, reductase, dehydratase. This multidomain structure sequence alignment analysis suggest that ZmsA member polyketide synthase family....
Abstract Background Extensive use of antibiotics has fostered the emergence superbugs that are resistant to multidrugs, which becomes a great healthcare and public concern. Previous studies showed quorum sensing signal DSF (diffusible factor) not only modulates bacterial antibiotic resistance through intraspecies signaling, but also affects tolerance interspecies communication. These findings motivate us exploit possibility using its structurally related molecules as adjuvants influence...
Antarctic terrestrial biodiversity faces multiple threats, from invasive species to climate change. Yet no large-scale assessments of threat management strategies exist. Applying a structured participatory approach, we demonstrate that existing conservation efforts are insufficient in changing world, estimating 65% (at best 37%, at worst 97%) native taxa and land-associated seabirds likely decline by 2100 under current trajectories. Emperor penguins identified as the most vulnerable taxon,...
Abstract Conservation science is a crisis discipline in which the results of scientific enquiry must be made available quickly to those implementing management. We assessed extent research published since year 2000 20 conservation journals publicly available. Of 19,207 papers published, 1,667 (8.68%) are freely downloadable from an official repository. Moreover, only 938 (4.88%) meet standard definition open access material can reused providing attribution authors given. This compares poorly...
Purpose: Through collaboration between Archeworks, Inc., an alternative design program, and the Rehabilitation Institute of Chicago, items services designed to improve lives persons with stroke were developed. Method: After examining issues related from a perspective, photography class called Aphasia Talks was developed facilitate self-expression in aphasia goals reintegration, socialization, recreation, education, strengthening. A model based on with, rather than for, employed develop...
Abstract RNAs are well-suited to act as cellular sensors that detect and respond metabolite changes in the environment, due their ability fold into complex structures. Here, we introduce a genome-wide strategy called PARCEL experimentally identifies RNA aptamers vitro, high-throughput manner. By applying collection of prokaryotic eukaryotic organisms, have revealed 58 new three key metabolites, greatly expanding list natural aptamers. The newly identified exhibit significant sequence...
Abstract Antarctic specially protected areas (ASPAs) are a key regulatory mechanism for protecting environmental values. Previous evaluations of the effectiveness ASPA system focused on its representativeness and design characteristics, presenting compelling rationale systematic revision. Upgrading could increase representation values within ASPAs, but alone does not guarantee avoided loss or improvement those Identifying factors that influence ASPAs would inform management an with greatest...
Shorebirds have declined severely across the East Asian—Australasian Flyway. Many species rely on intertidal habitats for foraging, yet distribution and conservation status of these Australia remain poorly understood. Here, we utilised freely available satellite imagery to produce first map Australia. We estimated a minimum area 9856 km2, with Queensland Western supporting largest areas. Thirty-nine percent were protected in Australia, some primarily within marine areas (e.g. Queensland)...
Abstract Background Burkholderia cenocepacia employs both N-Acyl homoserine lactone (AHL) and cis -2-dodecenoic acid (BDSF) quorum sensing (QS) systems in regulation of bacterial virulence. It was shown recently that disruption BDSF synthase RpfF Bc caused a reduction AHL signal production B. . However, how system influences is still not clear. Results We show here controls through novel signaling mechanism. Null mutation either the synthase, , or receptor, RpfR, substantial down-regulation...
ABSTRACT Plant pathogen Xanthomonas campestris pv. produces cis -11-methyl-2-dodecenoic acid (diffusible signal factor [DSF]) as a cell-cell communication to regulate biofilm dispersal and virulence production. Previous studies have demonstrated that DSF biosynthesis is dependent on the presence of RpfF, an enoyl-coenzyme A (CoA) hydratase, but synthetic mechanism influence host plant are still not clear. We show here exogenous addition juice or ethanol extract growth medium X. could...
Antarctica has been subject to direct human activity for a little over 200 years. In recent decades, the combination of sharp increases in and regional climate change, particularly around Antarctic Peninsula Scotia Arc, have placed terrestrial freshwater environment under increased threat non-native species introduction establishment. Policymakers, including those on Treaty Consultative Meeting’s Committee Environmental Protection, need accurate up-to-date information presence status within...
