Water in the city: visitation of animal wildlife to garden water sources and urban lakesNARA Subscribed
Providing garden water sources (e.g., ponds, bird baths) has become a popular and strongly promoted form of wildlife-friendly gardening, yet evidence of their use by animals is scarce and limited to a few taxa and water source types. We examined the prevalence, variety and potential value to animal wildlife of supplementary water provided within gardens of Hertfordshire, United Kingdom, using an online questionnaire and field...
Deconvolving mechanisms of particle flux attenuation using nitrogen isotope analyses of amino acidsNARA Subscribed
Particulate organic matter settling out of the euphotic zone is a major sink for atmospheric carbon dioxide and serves as a primary food source to mesopelagic food webs. Degradation of this organic matter encompasses a suite of mechanisms that attenuate flux, including heterotrophic metabolic processes of microbes and metazoans. The relative contributions of microbial and metazoan heterotrophy to flux attenuation, however, hav...
Small particles and heterotrophic protists support the mesopelagic zooplankton food web in the subarctic northeast Pacific OceanNARA Subscribed
A quantitative understanding of the mesopelagic zooplankton food web is key to development of accurate carbon budgets and geochemical models in marine systems. Here we use compound specific nitrogen stable isotope analysis of amino acids to quantify the trophic structure of the microzooplankton and mesozooplankton community during summer in the subarctic northeast Pacific Ocean during the EXport Processes in the Ocean from Rem...
Prolonging survival in good health is a fundamental societal goal. However, the leading determinants of disability-free survival in healthy older people have not been well established. Data from ASPREE, a bi-national placebo-controlled trial of aspirin with 4.7 years median follow-up, was analysed. At enrolment, participants were healthy and without prior cardiovascular events, dementia or persistent physical disability. Disab...
Distinguishing zooplankton fecal pellets as a component of the biological pump using compound‐specific isotope analysis of amino acidsNARA Subscribed
Zooplankton contribute a major component of the vertical flux of particulate organic matter to the ocean interior by packaging consumed food and waste into large, dense fecal pellets that sink quickly. Existing methods for quantifying the contribution of fecal pellets to particulate organic matter use either visual identification or lipid biomarkers, but these methods may exclude fecal material that is not morphologically dist...
Recruitment and growth of two small‐bodied resident fish species (Gobiidae and Atherinidae) in oligohaline, seasonally open lagoonsNARA Subscribed
Spatio‐temporal recruitment patterns, growth and survival of the Swan River goby Pseudogobius olorum and western hardyhead Leptatherina wallacei are described from two small, coastal lagoons on the south coast of Western Australia. In these lagoons, estuarine salinity dynamics were relatively stable over much of the autumn–spring period when freshwater inputs from rivers were reduced and there was no oceanic connection. Prefle...
Transport and attenuation of bacteria and bacteriophages in an alluvial gravel aquiferNARA Subscribed
The relative attenuation of rhodamine WT dye, two strains of Escherichia coli, Bacillus subtilis endospores, and the F‐RNA bacteriophage MS2 in an alluvial gravel aquifer was investigated in two tracing experiments at Burnham, near Christchurch, New Zealand. A simulated concentration curve was fitted to the observed breakthrough curves using the contaminant transport model AT123D, by optimising hydraulic conductivity (K), long...
