Field-Scale Production Optimization with Intelligent Wells
Authors: Ilamah Osho , Waterhouse Ross
Published: April 2018

Intelligent wells with inflow control valves enable flexible management of multiple reservoir intervals. In this paper, we describe model based optimization of inflow control valve settings for a producing North Sea field. A two step, non-invasive, iterative pattern search optimization algorithm is applied. The first step provides global search of the feasible region using a discrete genetic algorithm whereas the second step provides local search around the incumbent solution. To account for reservoir uncertainties, optimization is performed on a diverse set of history matched reservoir model realizations, within an automated framework. The results show a significant improvement in predicted reservoir production performance over the remaining life of the field.
Sulphate in Original Reservoir Chalk Rocks: Release of Sulphate by Desulphated Sea Water and Effects on Wettability
Authors: Fjelde Ingebret
Published: April 2018

Injection of sea water (SW) into oil reservoirs for pressure maintenance or sweep can in some cases cause reservoir souring, sulphate scaling and formation damage. Change of injection water from SW to desulphated sea water (D-SW) may reduce these problems. The objective for the presented study was to investigate the interactions between reservoir chalk rocks and D-SW, and to determine the effects of low sulphate concentration in formation water (FW) on oil production from reservoir chalk.

FW, SW, D-SW (synthetic) and water from a sulphate removal plant (SRPW) were injected to reservoir chalk plugs. Effluent samples were analysed for sulphate, pH and elements to investigate the interactions between brines and minerals. During the brine injections, the potential for formation damage was also evaluated by measuring differential pressure across the core plugs. Reservoir chalk plugs were prepared using FW without sulphate and FW with sulphate concentration as in real FW, to investigate the effect of initial sulphate on spontaneous imbibition and viscous flooding.

No pressure build-up was observed when FW, SW, D-SW and SRPW were injected to the reservoir chalk plugs. Sulphate effluent peaks were observed during injection of FW, D-SW and SRPW to the reservoir chalk. The effluent pH was higher in the D-SW and SRPW injections than in the FW injections. The compositions of effluent samples confirmed the interactions between the reservoir chalk and these brines. Both spontaneous imbibition and viscous flooding with SW showed that the reservoir chalk with initial sulphate was more water-wet than the same chalk without initial sulphate.

Injection of D-SW will reduce the amount of sulphate produced in the oil fields, but the study has shown that sulphate will be produced due to the release of sulphate from the original reservoir chalks. Since SW has been reported to improve the oil recovery, it is important to compare the oil recovery potential for D-SW and SW before the type of injection brine is selected. It will then be important to prepare the reservoir rock with the correct amount of initial sulphate.
A Comparison of Clean-Up Efficiency of Multiple Fractured Horizontal Wells and Hydraulically Fractured Vertical Wells in Tight Gas Reservoirs
Authors: Nasriani Hamid Reza , Jamiolahmady Mahmoud
Published: April 2018

Hydraulic fracturing is a well-established stimulation technique especially for unconventional reservoirs. However, sometimes its performance is less than expected due to poor cleanup of the injected fracture fluid. There are publications studying the clean-up efficiency of hydraulic fractures in vertical wells, however, there is little information in this area for multiple fractured horizontal wells, MFHWs.

This paper compares the fracture cleanup efficiency of a hydraulically fractured vertical well (VW) with that of multiple fractured horizontal wells (MFHWs) using numerical simulations and statistical approaches.

In these simulations, twelve parameters related to fracture and matrix relative permeability and matrix capillary pressure were varied simultaneously based on the two-level full factorial experimental design statistical method. Gas production loss (GPL), as the response term, was calculated and input into Response Surface Model. In each set, the correlation between parameters and GPL was established and compared to investigate the post-fracturing cleanup efficiency.

Results show that the direction of impact of parameters for VW and MFHW are similar except for the matrix permeability, Km. This difference is attributed to the flow geometry and how the well has been completed. This observation underlines that in MFHWs, the cleanup mechanism and the sequences of the importance of pertinent parameters could be different from those of the VWs.

Results also indicate that matrix Book's type capillary pressure pertinent parameters are more important in the MFHW sets whilst Corey type relative permeability parameters are more important in VWs. These observations suggest that having a higher capillary pressure is more important in MFHWs because it results in more FF imbibition into the matrix and consequently less resistance to gas flow within the fracture. Several MFHW models with different number of fractures were constructed, which demonstrated that although the impact on well productivity is significant, its impact on clean-up performance was minimal.

These results improve our understanding of VWs and MFHWs clean-up and design of such costly operations.
Effect of Variation in Fractures Conductivity and Well Location on Pressure Transient Response from Fractured Reservoirs
Authors: Egya David , Sebastian Geiger , Corbett Patrick W.
Published: April 2018

Fractures often influence production behaviour in hydrocarbon reservoirs, yet the pressure transients observed in the wells may not show the conventional well-test signatures. In this case, the effect of fractures on production would be misinterperted or even completely missed. Fracture networks are commonly multi-scale and properties including aperture (or conductivity), length, connectivity and distribution vary greatly within a reservoir. The heterogeneous nature of fractured reservoirs make them very difficult to characterise and develop. In addition, the location of a producer within the fracture network also control flow rates and affect the pressure response; however, conventional well-test analysis assumes that the producer is located in symmetrical fracture networks. To improve our understanding of fracture flow behaviour from well-test data, and in order to better characterise the impact of fractures on reservoir performance, we investigate the effect of variations in fracture conductivity and location of the producer in the fracture network on the pressure transient responses.

Naturally fractured reservoirs (NFR) with well-connected fracture networks are traditionally simulated using the Dual-Porosity (DP) model. However, several studies have shown that the classic DP response (V-shape) corresponding to the DP model is an exceptional behaviour applicable only to certain reservoir geology and does not apply to all NFR. To overcome the limitations of the characteristic flow behaviour inherent to this model, we employ Discrete Fracture Matrix (DFM) modelling technique and an unstructured-grid reservoir simulator to generate synthetic pressure transients in all fracture networks that we analysed. Our rigorous and systematic geoengineering workflow enables us to correlate the pressure transients to the known geological features of the simulated reservoir model.

We observed that depending on the location of the producer in the fracture network and the properties of the fractures that the producer intercepts, the synthetic pressure transients vary significantly. We therefore use these insights to quantify the impact of variation in fracture conductivity and producer location on fracture flow behaviour and systematically present interpretations to these behaviours. Our findings enable us to interpret some unconventional features of intersecting fractures with variable conductivity. We observed that the behaviour of two intersecting fractures where the well asymmetrically intercepts a finite-conductivity fracture can be similar to that of a well intercepting a fracture in a connected fracture network with uniform fracture conductivity. Furthermore, a well intercepting a finite-conductivity fracture in NFR with both finite- and infinite-conductivity fractures would yield a dual-porosity response that may otherwise be absent if the fracture network is assumed to have uniform conductivity.

Published: April 2018

O artigo apresenta uma nova metodologia para a coordenação do trabalho de uma equipe dispersa fisicamente chamada Autorregulação algorítmica (AA). A metodologia se baseia em conceitos recentes de redes sociais e mérito individual. Os membros da equipe assumem papéis igualitários e se mantêm logados voluntariamente a sessões de AA por parte do seu tempo (por exemplo, duas horas por dia), criando logs periódicos — frases curtas — que desejam compartilhar com os demais envolvidos nas atividades da equipe. Estes logs são agregados publicamente em um website e são validados pelos pares após o fim da sessão, da mesma forma que se faz na revisão de código. Preferencialmente, um breve screencast é gravado ao final de casa sessão para tornar os logs de AA mais compreensíveis. Esta metodologia se demonstrou adequada para aumentar a eficiência de equipes dispersas fisicamente trabalhando em projetos de Desenvolvimento de Software Global (GSD), conforme observado em nossa experiência em situações de uso cotidiano. O aumento de eficiência é obtido principalmente por meio de: 1) comunicação assíncrona e sob demanda em conjunto com a documentação dos produtos do trabalho e processos, e 2) necessidade reduzida de gestão centralizada, reuniões ou relatórios que consomem tempo. Assim, a metodologia AA legitima e facilita as atividades de uma equipe de desenvolvimento de software distribuída. Ela possibilita que outras entidades disponham de meios para financiar essas atividades, possibilitando que novos e concretos modelos de negócio se tornem possíveis para desenvolvimentos de software muito distribuídos. A AA foi proposta, em sua essência, como uma forma de possibilitar a auto-replicação de iniciativas de atividade hacker. Estes argumentos são discutidos com base em um estudo de caso real de atuação de uma equipe hacker de software livre distribuído chamada Lab Macambira.

Objective: The aim of this study was the evaluation of the characteristics and treatment results of women, who were brought to the intensive care unit due to severe obstetric morbidity, together with severe and acute complications in pregnancy.Study Design: Pregnant and puerperal women treated in the intensive care unit of a tertiary care center during two years of time were included in this study, and their files were scanned retrospectively. Patients’ demographic characteristics, length of stay, point of entry, neonatal results, birth statuses and modes of delivery, hemodynamic data, and histories were recorded. The qualitative data were evaluated by the Pearson Chi-squared, Fisher Freeman Halton, and Fisher’s Exact tests.Results: In the two-year period, 16,728 births occurred at our hospital. 68 cases among them were accompanied with severe maternal morbidity, and 2 maternal deaths were observed in our clinic. Of the cases, 58.8% (n=40) had severe hypertensive diseases, whereas 35.3% of the cases (n=24) had obstetric complications that developed due to bleeding. While 40% of the cases (n=16) with hypertension had severe pre-eclampsia, 35% of the cases (n=14) had eclampsia and 25% (n=10) had HELLP.Conclusions: The most important reasons for severe maternal morbidity are the complications related to obstetric bleeding and hypertensive diseases related to pregnancy. Early diagnosis of the obstetric complication risk factors is necessary for preventing maternal morbidity. Antenatal follow-ups and the births of high risk pregnancy patients should be performed in tertiary centers.
Improving river stage forecast by bed reconstruction in sinuous bends
Authors: Lin Yan-Ting , Chen Wei-Bo , Su Yuan-Fong , Han Jen-Yu , Jang Jiun-Huei
Published: April 2018

Bed topography in river bends is highly non-uniform as a result of the spiral motion of fluid and sediment transports related to channel curvature. To grasp a full understanding of geomorphology and hydrology in natural river bends, detailed bed topography data are necessary, but are usually not of high enough quality and so require further interpolation for sophisticated studies. In this paper, an algorithm is proposed that is particularly suited to bathymetry interpolation in rivers with apparent bends. The thalweg and the two banks are used as geographical features to ensure that a concave cross-sectional bed-form can be found in bend geometry, while linear interpolations are conducted in the in accordance with secondary and main stream currents, respectively. In comparison with conventional spatial interpolation methods, the proposed algorithm is validated to ensure better performance in generating smooth and accurate bed topography in channel bends, which results in better predictions of river stage by 2D hydrodynamic simulation in practical field tests.
Sewer catchment effects on wastewater and biosolids odour management
Authors: Fisher Ruth , Shammay Ari , Alvarez–Gaitan Juan Pablo , Stuetz Richard M.
Published: April 2018

The composition of wastewater in sewer catchments is known to affect the performance of wastewater treatment plants (WWTPs). However, there is limited knowledge as to how catchment characteristics, such as types of catchment industries, impact odour emissions from downstream sludge processing and biosolids management. Odorous emissions from biosolids processing at WWTPs can represent a significant community impact when the local population is exposed to odours. The main odorants emitted from biosolids are volatile sulfur compounds (VSCs), however, volatile organic compounds (VOCs) in emissions may also be perceptable after the removal of VSCs in odour abatement systems. Types of compounds present in emissions throughout biosolids processing at five WWTPs of varying sizes and levels of treatment (primary only and primary and secondary) were analysed. The ratio of total VSCs to VOCs in emissions, and the sensorial importance of each class varied between the sites. As a number of the VOCs in emissions were of industrial origin, this variation is likely dependent on industrial flows into the upstream sewer catchment. The impact of different emission compositions on both activated carbon and biologically based odour abatement systems were discussed.
Diverse Targeted Approaches to Battle Multidrug Resistance in Cancer

Published: April 2018

:

The efficacy of successful cancer therapies is frequently hindered by the development of drug
resistance in the tumor. The term ‘drug resistance’ is used to illustrate the decreased effectiveness of a
drug in curing a disease or alleviating the symptoms of the patient. This phenomenon helps tumors to survive
the damage caused by a specific drug or group of drugs. In this context, studying the mechanisms of
drug resistance and applying this information to design customized treatment regimens can improve therapeutic
efficacy as well as the curative outcome. Over the years, numerous Multidrug Resistance (MDR)
mechanisms have been recognized and tremendous effort has been put into developing agents to address
them. The integration of data emerging from the elucidation of molecular and biochemical pathways and
specific tumor-associated factors has shown tremendous promise within the oncology community for improving
patient outcomes. In this review, we provide an overview of the utility of these molecular and biochemical
signaling processes as well as tumor-associated factors associated with MDR, for the rational
selection of cancer treatment strategies.
Cytochrome P450S and Alcoholic Liver Disease
Authors: Lu Yongke , Cederbaum Arthur I.
Published: April 2018

Alcohol consumption causes liver diseases, designated as Alcoholic Liver Disease (ALD). Because
alcohol is detoxified by alcohol dehydrogenase (ADH), a major ethanol metabolism system, the development of
ALD was initially believed to be due to malnutrition caused by alcohol metabolism in liver. The discovery of the
microsomal ethanol oxidizing system (MEOS) changed this dogma. Cytochrome P450 enzymes (CYP) constitute
the major components of MEOS. Cytochrome P450 2E1 (CYP2E1) in MEOS is one of the major ROS generators
in liver and is considered to be contributive to ALD. Our labs have been studying the relationship between
CYP2E1 and ALD for many years. Recently, we found that human CYP2A6 and its mouse analog CYP2A5 are
also induced by alcohol. In mice, the alcohol induction of CYP2A5 is CYP2E1-dependent. Unlike CYP2E1,
CYP2A5 protects against the development of ALD. The relationship of CYP2E1, CYP2A5, and ALD is a major
focus of this review.
Melatonin Treatment Enhances Aβ Lymphatic Clearance in a Transgenic Mouse Model of Amyloidosis
Authors: Pappolla M.A. , Matsubara E. , Vidal R. , Pacheco-Quinto J. , Poeggeler B. , Zagorski M. , Sambamurti K.
Published: April 2018

Background:

It has been postulated that inadequate clearance of the amyloid β protein (Aβ)
plays an important role in the accumulation of Aβ in sporadic late onset Alzheimer's disease (AD).
While the blood brain barrier (BBB) has taken the center stage in processes involving Aβ clearance, little
information is available about the role of the lymphatic system. We previously reported that Aβ is
cleared through the lymphatic system. We now assessed lymphatic Aβ clearance by treating a mouse
model of AD amyloidosis with melatonin, an Aβ aggregation inhibitor and immuno-regulatory neurohormone.

Objective:

To confirm and expand our initial finding that Aβ is cleared through the lymphatic system.
Lymphatic clearance of metabolic and cellular “waste” products from the brain into the peripheral lymphatic
system has been known for a long time. However, except for our prior report, there is no additional
experimental data published about Aβ being cleared into peripheral lymph nodes.

Methods:

For these experiments, we used a transgenic mouse model (Tg2576) that over-expresses a mutant
form of the Aβ precursor protein (APP) in the brain. We examined levels of Aβ in plasma and in
lymph nodes of transgenic mice as surrogate markers of vascular and lymphatic clearance, respectively.
Aβ levels were also measured in the brain and in multiple tissues.

Results:

Clearance of Aβ peptides through the lymphatic system was confirmed in this study. Treatment
with melatonin led to the following changes: 1-A statistically significant increase in soluble monomeric
Aβ40 and an increasing trend in Aβ42 in cervical and axillary lymph nodes of treated mice. 2-
Statistically significant decreases in oligomeric Aβ40 and a decreasing trend Aβ42 in the brain.

Conclusion:

The data expands on our prior report that the lymphatic system participates in Aβ clearance
from the brain. We propose that abnormalities in Aβ clearance through the lymphatic system may contribute
to the development of cerebral amyloidosis. Melatonin and related indole molecules (i.e., indole-
3-propionic acid) are known to inhibit Aβ aggregation although they do not reverse aggregated Aβ or
amyloid fibrils. Therefore, these substances should be further explored in prevention trials for delaying
the onset of cognitive impairment in high risk populations.
Epithelial Organotypic Cultures: A Viable Model to Address Mechanisms of Carcinogenesis by Epitheliotropic Viruses
Authors: Termini Lara , Boccardo Enrique
Published: April 2018

In vitro culture of primary or established cell lines is one of the leading techniques in many
areas of basic biological research. The use of pure or highly enriched cultures of specific cell types obtained
from different tissues and genetics backgrounds has greatly contributed to our current understanding
of normal and pathological cellular processes. Cells in culture are easily propagated generating an
almost endless source of material for experimentation. Besides, they can be manipulated to achieve gene
silencing, gene overexpression and genome editing turning possible the dissection of specific gene functions
and signaling pathways. However, monolayer and suspension cultures of cells do not reproduce the
cell type diversity, cell-cell contacts, cell-matrix interactions and differentiation pathways typical of the
three-dimensional environment of tissues and organs from where they were originated. Therefore, different
experimental animal models have been developed and applied to address these and other complex
issues in vivo. However, these systems are costly and time consuming. Most importantly the use of animals
in scientific research poses moral and ethical concerns facing a steadily increasing opposition from
different sectors of the society. Therefore, there is an urgent need for the development of alternative in
vitro experimental models that accurately reproduce the events observed in vivo to reduce the use of animals.
Organotypic cultures combine the flexibility of traditional culture systems with the possibility of
culturing different cell types in a 3D environment that reproduces both the structure and the physiology
of the parental organ. Here we present a summarized description of the use of epithelial organotypic for
the study of skin physiology, human papillomavirus biology and associated tumorigenesis.

Authors: Yang Hui , Yang Yinxiang , Qu Suqing , Wang Zhaoyan , Lu Wei , Liu Fang , Liu Weipeng , Wang Qian , Sharma Aruna , Sharma Hari , Luan Zuo
Published: April 2018

Objective: To investigate growth factor changes in cerebrospinal fluid (CSF) of children
with mental retardation (MR) before and after neural precursor cell transplantation (NPCT), in an attempt
to provide experimental support for the clinical treatment of MR with NPCT.

Methods:

The study comprised of 28 MR children who received twice NPCT in our hospital. CSF was
collected at both times of NPCT to assess growth factors by ELISA. In addition, the content of insulinlike
growth factor 1 (IGF-1) in CSF was assayed to determine possible correlations between IGF-1
changes and the short-term therapeutic effect of NPCT.

Results:

Of all the growth factors detected in CSF, only IGF-1 was increased significantly after NPCT
(P<0.05). Fifteen of the twenty-eight MR children achieved short-term therapeutic efficacy, whereby
the content of IGF-1 after NPCT was significantly higher than that before NPCT (P<0.05). There was
no difference in IGF-1 content before and after NPCT in the remaining 13 MR children without shortterm
therapeutic effect (P=0.657). There was a significant difference in IGF-change between the two
groups of patients (P<0.05).

Conclusion:

IGF-1 may be one of the mechanisms contributing to the therapeutic effect of NPCT.
Experimental Study on the Effect of Moisture Content on Hysteretic Behavior of Reinforced Concrete Columns
Authors: Lv Wenjuan , Liu Baodong , Li Ming , Li Lin , Zhang Pengyuan
Published: April 2018

Background:

For reinforced concrete structures under different humid conditions, the mechanical properties of concrete are significantly affected by the moisture content, which may result in a great change of the functional performance and bearing capacity.

Objective:

This paper presents an experiment to investigate the influence of the moisture content on the dynamic characteristics and hysteretic behavior of reinforced concrete column.

Results:

The results show that the natural frequency of reinforced concrete columns increases quickly at an early stage of immersion, but there is little change when the columns are close to saturation; the difference between the natural frequencies before and after cyclic test grows as the moisture content rises. The damping ratio slightly decreases first and then increases with the increase of moisture content; the damping ratio after the cyclic test is larger than before the test due to the development of the micro-cracks.

Conclusion:

The trend of energy dissipation is on the rise with increasing moisture content, although at an early stage, it decreases slightly. According to the experimental result, a formula for the moisture content on the average energy dissipation of reinforced concrete columns is proposed.
Short-Term Crossover Study on the Effect of Orthogonalized Deep-Grooved Posterior Artificial Teeth on the Masticatory Efficiency of Complete Denture Wearers
Authors: Hashimoto Yuki , Sugimoto Kyoko , Tanaka Yuki , Sugimoto Hikaru , Minagi Shogo
Published: April 2018

Background:

Mastication has been regarded to play an important role in achieving quality daily life for the elderly. On the occlusal surface of posterior artificial teeth, parallel grooves of 1 mm depth and 1 mm width with an inter-groove distance of 2 mm have been found to significantly improve masticatory efficiency on a mechanical simulator.

Materials and Methods:

In the present study, the effect of the grooved design on masticatory efficiency in edentulous subjects using a short-term crossover trial was evaluated. Six edentulous participants, 1 male and 5 females, were assigned into two groups. One received duplicated complete dentures with grooved molars first, and the other received duplicated complete dentures with conventional molars first. The design of the teeth was crossover after evaluating masticatory efficiency. Raw carrot, raw lettuce and mixed foodstuffs were used to evaluate masticatory efficiency. Subjects were instructed to masticate 20 strokes and arbitrary strokes until they felt like swallowing.

Results:

The number of masticatory strokes taken was significantly smaller using the grooved design (p<.05). Masticatory efficiency analysis revealed that the grooved design achieved significantly higher masticatory efficiency at 20 masticatory strokes for raw carrot and mixed foodstuffs (p<.05).

Conclusion:

Results show that compared with conventional lingualized occlusion, the grooved design accomplishes higher masticatory efficiency in vivo. Considering the distinction of this design that it can be applied to any existing denture occlusion, the design might help improve the dietary life of the elderly.
Antibacterial and Anti-inflammatory Potential of Morus alba Stem Extract
Authors: Yiemwattana Ichaya , Chaisomboon Niratcha , Jamdee Kusuma
Published: April 2018

Background:

Periodontitis, a chronic inflammatory disease, is the leading cause of tooth loss in adults. Evidence for the anti inflammatory activity ofM. albaStem Extract (MSE) in periodontal disease is limited.

Objective:

The study aimed to investigate the inhibitory effect of MSE on the growth of periodontopathic bacteria and expression of interleukin (IL)-6 and IL-8 inPorphyromonas gingivalisLipopolysaccharide (LPS)-stimulated human Periodontal Ligament (hPDL) fibroblasts.

Methods:

The antimicrobial activities of MSE were tested againstP. gingivalisandActinobacillus actinomycetemcomitansby the disk diffusion, the minimum inhibitory concentration and the minimal bactericidal concentration methods. Cytotoxicity ofP. gingivalisLPS and MSE on hPDL fibroblasts was determined by MTS assay. The expression of cytokines (IL-6 and IL-8) mRNA and proteins in hPDL fibroblasts was measured using the reverse transcription-qPCR and enzyme-linked immunosorbent assay, respectively.

Results:

MSE exhibited antibacterial activities againstP. gingivalisandA. actinomycetemcomitanswith the zones of inhibition of 10.00 ± 0.33 mm and 17.33 ± 0.58 mm, respectively. MIC and MBC values for MSE againstP. gingivaliswere 62.5 μg/ml. The MIC and MBC values againstA. actinomycetemcomitanswere 250 μg/mL and 500 μg/ml, respectively.P. gingivalisLPS was shown to mediate the expression of pro-inflammatory cytokines in hPDL fibroblasts. However, treatment with MSE concentrations of 2.5 and 5.0 μg/ml significantly suppressedP. gingivalisLPS-induced IL-6 and IL-8 mRNA and protein expression (p< 0.05).

Conclusion:

The present study demonstrates that MSE has antibacterial activity against two putative periodontal pathogens. MSE suppressed IL-6 and IL-8 expression inP. gingivalisLPS-stimulated hPDL fibroblasts, indicating a possible anti-inflammatory effect. Thus, it is a potential adjunctive agent for the treatment of periodontitis.
Painted Redstarts (Myioborus Pictus) Attack Larger Prey when Using Flush-Pursue Strategy
Authors: Jablonski Piotr G. , Lee Sang-im
Published: April 2018

Introduction:

Prey escape reaction in insects is an antipredatory adaptation that is mediated by prey neural escape circuits with specific sensory properties.

Methods:

Certain insectivorous birds, flush-pursuers, exploit this visual sensitivity by employing conspicuous pivoting movements of spread tail and wings to flush the prey into the air where it is available for chase in aerial pursuits. Although it is known that this strategy increases the number of insects attacked, no information has been published on the size distribution of arthropods attacked using flush-pursue strategyvs. traditional gleaning and pecking off substrate strategy.

Results:

Based on one season of observational data of foraging redstarts (Myioborus pictus) we show that prey items that were flushed and chased were on average larger than prey pecked off of substrates.

Conclusion:

This may be one of the benefits from flush-pursue foraging – a strategy that is probably costly in terms of energy demands.
