Many ecological indicators have been proposed to detect and describe the effects of fishing on marine ecosystems, but few evaluated formally. Here, simulation models two systems off southeastern Australia (a large embayment, an EEZ-scale regional ecosystem) are used evaluate performance a suite indicators. The cover species, assemblages, habitats, including quantities derived from such as Ecopath. models, based Atlantis framework, incorporate several gears, also confounding impacts other...
Abstract Species distribution models (SDMs) are widely applied to understand the processes governing spatial and temporal variation in species abundance but often do not account for measurement errors such as false negatives positives. We describe unmarked , a package freely available open‐source R software that provides complete workflow modelling while explicitly accounting errors. Here we focus on recent advances functionality support multi‐species, multi‐state, multi‐season data, well...
To determine the symptomatic and urodynamic outcome of elective prostatectomy to establish whether is influenced or can be predicted by preoperative measurements.Prospective non-randomised study with follow up at a mean 11 months after operation. Most men were assessed jointly urologist general practitioner.Department urology in teaching hospital serving large district population.253 Men listed for because symptoms low urinary flow rates (less than 15 ml/s) excluding those already on waiting...
We evaluated whether fruit selection by autumn-migrating birds at an important stopover site in southern New England was related to water-soluble antioxidant content of fruits. measured total anthocyanins, phenolics, and capacity fruits from common native non-native plant species this estimates free-living birds. Birds selected certain over others, with arrowwood (Viburnum recognitum, V. dentatum) consumed the highest rate, followed Virginia creeper (Parthenocissus quinquefolia) much lower...
Femtosecond X-ray absorption spectroscopy (XAS) is a powerful method to investigate the dynamical behavior of system after photoabsorption in real time. So far, application this technique has remained limited large-scale facilities, such as femtosliced synchrotrons and free-electron lasers (FEL). In work, we demonstrate femtosecond time-resolved soft-X-ray liquid samples by combining sub-micrometer-thin flat jet with high-harmonic tabletop source covering entire water-window range (284-538...
Summary— A postal survey among 2% of men in Leeds showed that the prevalence urinary stone disease is 3.8%. The upper tract and spontaneously passed stones increases progressively from 0.7% social class 5 to 5.0% 1 but bladder (0.7% group as a whole) independent class. There an initial peak commencing at age 20 having projected 90 5.7% second stones, about 50, with 1.9%. according order: single < divorced/separated married widowed men. family history tends be higher amongst relatives...
The behavioral decisions of migratory songbirds during migration stopovers can markedly influence the pace, efficiency, and success migration. An individual's fuel stores are considered in theory to directly dictate subsequent stopover behavior (e.g., extent foraging or vigilance, when depart), although such at must also consider atmospheric factors wind, precipitation) that energetic costs We conducted first study date manipulated newly arrived a site, evaluated their effect on movement...
Hydrogen bonding interactions between biological chromophores and their surrounding protein solvent environment significantly affect the photochemical pathways of chromophore its function. A common first step in dynamics these systems is excited state proton transfer noncovalently bound molecules, which stabilizes system against dissociation principally alters relaxation pathways. Despite such fundamental importance, studying across a hydrogen bond has proven difficult, leaving uncertainties...
We probe the dynamics of dissociating ${\mathrm{CS}}_{2}$ molecules across entire reaction pathway upon excitation. Photoelectron spectroscopy measurements using laboratory-generated femtosecond extreme ultraviolet pulses monitor competing dissociation, internal conversion, and intersystem crossing dynamics. Dissociation occurs either in initially excited singlet manifold or, via crossing, triplet manifold. Both product channels are monitored show that, despite being more rapid, dissociation...
Abstract Microbes in the intestines of mammals degrade dietary glycans for energy and growth. The pathways required polysaccharide utilization are functionally diverse; moreover, they unequally dispersed between bacterial genomes. Hence, assigning metabolic phenotypes to genotypes remains a challenge microbiome research. Here we demonstrate that glycan uptake gut bacteria can be visualized with fluorescent conjugates (FGCs) using epifluorescence microscopy. Yeast α-mannan...
Abstract Gut microbiomes, such as the microbial community that colonizes rumen, have vast catabolic potential and play a vital role in host health nutrition. By expanding our understanding of metabolic pathways these ecosystems, we will garner foundational information for manipulating microbiome structure function to influence physiology. Currently, knowledge relies heavily on inferences derived from metagenomics or culturing bacteria vitro. However, novel approaches targeting specific cell...
Abstract Site fidelity—returning repeatedly to the same site—can help many migratory species reduce uncertainty in their environment, especially when stopover periods leave little time explore and evaluate new habitat. Avian taxa, though, have shown wide variation levels of site fidelity during migration, few studies been able examine individual-level at fine spatiotemporal scales. We used a high-resolution GPS tracking dataset Numenius phaeopus (Whimbrel), long-distance shorebird, assess...
The cryptic behavior of migrating bats leaves us largely uninformed their seasonal distribution and abundance, important movement corridors, migration behaviors. However, models avian in relation to meteorological variables may prove useful describing patterns coastal bat activity. We pursued 2 primary objectives regarding regional autumn activity along the Atlantic Coast southern New England, United States, inferred from continuous acoustic monitoring: 1) evaluate hypotheses association...
Background and Purpose: The optimal postoperative drainage system for patients undergoing percutaneous nephrolithotomy (PCNL) has not yet been determined. Each of the different tubes available theoretical advantages disadvantages. objective this study was to determine if any one post-PCNL significant advantage over others. Patients Methods: Sixty were randomized either a 24F Re-entry tube (Group 1), an 8F pigtail catheter 2), or double-J stent 3) (N = 20 all groups). also had 18F Councill as...
The analysis of stable-hydrogen isotope ratios in feathers (δDf) allows researchers to investigate avian movements and distributions an extent never before possible. Nonetheless, natural variation δDf is poorly understood and, particular, its implications for predictive models based on isotopes remain unclear. We employed hierarchical linear modeling explore multiple levels the composition Northern Goshawk (Accipiter gentilis) feathers. examined (1) inter-individual among goshawks from same...
Stable-hydrogen isotope ratios (deuterium:protium; δD) in feathers enable researchers to evaluate patterns of avian movement and estimate the source areas migratory birds. However, variation feather δD remains inadequately described, thus confounding inferences origin. We assessed within a among between tracts three species immature raptors. Within contour feathers, measurements increased from distal section an adjacent, proximal section; magnitude increase varied with raptor species....
Despite the widespread use of stable isotopes in studies avian movement, key assumptions on which methodology is based remain unsubstantiated, including assumption that measurements hydrogen feathers (δDf) are consistent across time within same laboratory or among laboratories using analytical protocols and keratin standards. We tested this by remeasuring δDf from 211 raptor between laboratories. Initial repeat samples were prepared analyzed identical but distinct automated runs with staff...
