| 3 | Laparoscopic liver resection:Experience based guidelines显示文摘Laparoscopic liver resection(LLR) has been progressively developed along the past two decades. Despite initial skepticism, improved operative results made laparoscopic approach incorporated to surgical practice and operations increased in frequency and complexity. Evidence supporting LLR comes from case-series, comparative studies and meta-analysis. Despite lack of level 1 evidence, the body of literature is stronger and existing data confirms the safety, feasibility and benefits of laparoscopic approach when compared to open resection. Indications for LLR do not differ from those for open surgery. They include benign and malignant(both primary and metastatic) tumors and living donor liver harvesting. Currently, resection of lesions located on anterolateral segments and left lateral sectionectomy are performed systematically by laparoscopy in hepatobiliary specialized centers. Resection of lesions located on posterosuperior segments(1, 4a, 7, 8) and major liver resections were shown to be feasible but remain technically demanding procedures, which should be reserved to experienced surgeons. Hand-assisted and laparoscopy-assisted procedures appeared to increase the indications of minimally invasive liver surgery and are useful strategies applied to difficult and major resections. LLR proved to be safe for malignant lesions and offers some short-term advantages over open resection. Oncological results including resection margin status and long-term survival were not inferior to open resection. At present, surgical community expects high quality studies to base the already perceived better outcomes achieved by laparoscopy in major centers' practice. Continuous surgical training, as well as new technologies should augment the application of lap-aroscopic liver surgery. Future applicability of new technologies such as robot assistance and image-guided surgery is still under investigation. | fabricio ferreira coelho jaime arthur pirola kruger gilton marques fonseca raphael leonardo cunha araújo vagner birk jeismann marcos vinícius perini renato micelli lupinacci ivan cecconello paulo herman | 2016 | World Journal of Gastrointestinal Surgery2016，8，1： | 22 |
| 4 | Multisciplinary management of patients with liver metastasis from colorectal cancer显示文摘Colorectal cancer(CRC) is one of the leading causes of cancer-related death. Surgery, radiotherapy and chemotherapy have been till now the main therapeutic strategies for disease control and improvement of the overall survival. Twenty-five per cent(25%) of CRC patients have clinically detectable liver metastases at the initial diagnosis and approximately 50% develop liver metastases during their disease course. Twentythirty per cent(20%-30%) are CRC patients with metastases confined to the liver. Some years ago various studies showed a curative potential for liver metastases resection. For this reason some authors proposed the conversion of unresectable liver metastases to resectable to achieve cure. Since those results were published, a lot of regimens have been studied for resectability potential. Better results could be obtained by the combination of chemotherapy with targeted drugs, such as anti-VEGF and antiEGFR monoclonal antibodies. However an accurate selection for patients to treat with these regimens and to operate for liver metastases is mandatory to reduce the risk of complications. A multidisciplinary team approach represents the best way for a proper patient management. The team needs to include surgeons, oncologists, diagnostic and interventional radiologists with expertise in hepatobiliary disease, molecular pathologists, and clinical nurse specialists. This review summarizes the most important findings on surgery and systemic treatment of CRC-related liver metastases. | Kathleen De Greef Christian Rolfo Antonio Russo Thiery Chapelle Giuseppe Bronte Francesco Passiglia Andreia Coelho Konstantinos Papadimitriou Marc Peeters | 2016 | World Journal of Gastroenterology2016，22，32： | 22 |
| 5 | Hepatitis B virus prevalence and transmission risk factors in inflammatory bowel disease patients at Clementino Fraga Filho university hospital显示文摘AIM: To evaluate the prevalence of hepatitis B virus (HBV) infection in inflammatory bowel disease (IBD) patients that followed up in our hospital and try to identify the possible risk factors involved in this infection transmission. METHODS: This was a cross-sectional study for which 176 patients were selected according to their arrival for the medical interview. All these patients had already IBD diagnosis. The patient was interviewed and a questionnaire was filled out. RESULTS: In the group of 176 patients whom we examined, we found that 17% (30) were anti-HBc positive. Out of 30 patients with positive anti-HBc, 2.3% (4) had positive HBsAg and negative HBV-DNA. In an attempt to identify the possible HBV infection transmission risk factors in IBD patients, it was observed that 117 patients had been submitted to some kind of surgical procedure, but only 24 patients had positive anti-HBc (P = 0.085). It was also observed that surgery to treat IBD complications was not a risk factor for HBV infection transmission, since we did not get a statically significant P value. However, IBDpatients that have been submitted to surgery to treat IBD complications received more blood transfusions then patients submitted to other surgical interventions (P = 0.015). CONCLUSION: There was a high incidence of positive anti-HBc (17%) and positive HBsAg (2.3%) in IBD patient when compared with the overall population (7.9%). | Yolanda Faia Manhes Tolentino Homero Soares Fogaa Cyrla Zaltman Lia Laura Lewis Ximenes Henrique Sérgio Moraes Coelho | 2008 | World Journal of Gastroenterology2008，14，20： | 10 |
| 6 | Acute effects of physical exercise in type 2 diabetes: A review显示文摘The literature has shown the efficiency of exercise in the control of type 2 diabetes(T2D), being suggested as one of the best kinds of non-pharmacological treatments for its population. Thus, the scientific production related to this phenomenon has growing exponentially. However, despite its advances, still there is a lack of studies that have carried out a review on the acute effects of physical exercise on metabolic and hemodynamic markers and possible control mechanisms of these indicators in individuals with T2 D, not to mention that in a related way, these themes have been very little studied today. Therefore, the aim of this study was to organize and analyze the current scientific production about the acute effects of physical exercise on metabolic and hemodynamic markers and possible control mechanisms of these indicators in T2 D individuals. For such, a research with the following keywords was performed:-exercise; diabetes and post-exercise hypotension; diabetes and excess post-exercise oxygen consumption; diabetes and acute effects in PUBMED, SCIELO and HIGHWIRE databases. From the analyzed studies, it is possible to conclude that, a single exercise session can promote an increase in the bioavailability of nitric oxide and elicit decreases in postexercise blood pressure. Furthermore, the metabolic stress from physical exercise can increase the oxidation of carbohydrate during the exercise and keep it, in high levels, the post exercise consumption of O2, this phenomenon increases the rate of fat oxidation during recovery periods after exercise, improves glucose tolerance and insulin sensitivity and reduces glycemia between 2-72 h, which seems to be dependent on the exercise intensity and duration of the effort. | Ricardo Yukio Asano Marcelo Magalhes Sales Rodrigo Alberto Vieira Browne José Fernando Vila Nova Moraes Hélio José Coelho Júnior Milton Rocha Moraes Hebert Gustavo Simoes | 2014 | World Journal of Diabetes2014，5，5： | 8 |

| 8 | Bone marrow-derived monocyte infusion improves hepatic fibrosis by decreasing osteopontin,TGF-β1,IL-13 and oxidative stress显示文摘AIM To evaluate the therapeutic effects of bone marrowderived CD11b+CD14+ monocytes in a murine model of chronic liver damage. METHODS Chronic liver damage was induced in C57BL/6 mice by administration of carbon tetrachloride and ethanol for 6 mo. Bone marrow-derived monocytes isolated by immunomagnetic separation were used for therapy. The cell transplantation effects were evaluated by morphometry,biochemical assessment,immunohistochemistry and enzyme-linked immunosorbent assay. RESULTS CD11b+CD14+ monocyte therapy significantly reduced liver fibrosis and increased hepatic glutathione levels. Levels of pro-inflammatory cytokines,including tumor necrosis factor-α,interleukin(IL)-6 and IL-1β,in addition to pro-fibrotic factors,such as IL-13,transforming growth factor-β1 and tissue inhibitor of metalloproteinase-1 also decreased,while IL-10 and matrix metalloproteinase-9 increased in the monocytetreated group. CD11b+CD14+ monocyte transplantation caused significant changes in the hepatic expression of α-smooth muscle actin and osteopontin. CONCLUSION Monocyte therapy is capable of bringing about improvement of liver fibrosis by reducing oxidative stress and inflammation,as well as increasing antifibrogenic factors. | Veruska Cintia Alexandrino de Souza Thiago Almeida Pereira Valéria Wanderley Teixeira Helotonio Carvalho Maria Carolina Accioly Brelaz de Castro Carolline Guimaraes D’assuncao Andreia Ferreira de Barros Camila Lima Carvalho Virgínia Maria Barros de Lorena Vláudia Maria Assis Costa Alvaro Aguiar Coelho Teixeira Regina Celia Bressan Queiroz Figueiredo Sheilla Andrade de Oliveira | 2017 | World Journal of Gastroenterology2017，23，28： | 6 |
| 9 | Duodenal stenting for malignant gastric outlet obstruction:Prospective study显示文摘AIM:To evaluate the results of duodenal stenting for palliation of gastroduodenal malignant obstruction by using a gastric outlet obstruction score (GOOS).METHODS:A prospective,non-randomized study was performed at a tertiary center between August 2005 and April 2010.Patients were eligible if they had malignant gastric outlet obstruction (GOO) and were not candidates for surgical treatment.Medical history and patient demographics were collected at baseline.Scheduled interviews were made on the day of the procedure and 15,30,90 and 180 d later or unscheduled as necessary.RESULTS:Fifteen patients (6 male,9 female;median age 61 years) with GOO who had undergone duodenal stenting were evaluated.Ten patients had metastasis at baseline (66.6%) and 14 were unable to accept oral intake (93.33%),including 7 patients who were using a feeding tube.Laboratory data showed biliary obstruction in eight cases (53.33%);all were submitted to biliary drainage.Two patients developed obstructive symptoms due to tumor ingrowth after 30 d and another due to tumor overgrowth after 180 d.Two cases of stent migration occurred.A good response to treatment was observed,with a mean time of approximately 1 d (19 h) until toleration of a liquid diet and slightly more than 2 d for both soft solids (51 h) and a solid food/normal diet (55 h).The mean time to first failure to maintain liquid intake (GOOS ≥ 1) was 93 d.During follow-up,the mean time to first failure to maintain the previously achieved GOOS of 2-3 (solid/semi-solid food),considered technical failure,was 71 d.On the basis of oral intake a GOOS is defined:0 for no oral intake;1 for liquids only;2 for soft solids only;3 for lowresidue or full diet.CONCLUSION:Enteral stenting to alleviate gastroduodenal malignant obstruction improves quality of life in patients with limited life expectancy,which can be evaluated by using a GOO scoring system. | Eduardo Guimaräes Hourneaux Moura Flávio Coelho Ferreira Spencer Cheng Diogo Turiani Hourneaux Moura Paulo Sakai Bruno Zilberstain | 2012 | World Journal of Gastroenterology2012，18，9： | 5 |
| 10 | Critical analysis of molluscicide application in schistosomiasis control programs in Brazil显示文摘In Brazil,Biomphalaria glabrata,B.tenagophila,and B.straminea are naturally infected by the trematode Schistosoma mansoni,the causative agent of schistosomiasis.Despite decades of governmental efforts through official control programs,schistosomiasis remains an important public health problem in the country:thousands of people are infected with the trematode each year and millions live in endemic areas.The World Health Organization recommends using a combination of molluscicide(niclosamide)and mass chemotherapy to control the transmission of schistosomiasis,with this treatment successfully reducing the morbidity of the disease.In the past,niclosamide has been used in official schistosomiasis control programs in Brazil.However,as B.glabrata recolonizes even after molluscicide application,the use of molluscicides has gradually decreased in the country until they were discontinued in 2002,mainly due to the rising global pressure to preserve the environment and the difficulties of obtaining licenses from the Brazilian Ministry of Environment to use toxic substances in aquatic ecosystems.Therefore,the discovery of new molluscicides,which could be more selective to Biomphalaria species and less harmful to the aquatic ecosystem,is necessary.In addition,political efforts to sensitize funders to provide grants for this field of research are required.In this context,this article aims to make a critical analysis of molluscicide application in schistosomiasis control programs in Brazil. | PMZ Coelho RL Caldeira | 2016 | Infectious Diseases of Poverty2016，5，1： | 4 |

| 12 | Umbilical hernia in patients with liver cirrhosis: A surgical challenge显示文摘Umbilical hernia occurs in 20% of the patients with liver cirrhosis complicated with ascites. Due to the enormous intraabdominal pressure secondary to the ascites, umbilical hernia in these patients has a tendency to enlarge rapidly and to complicate. The treatment of umbilical hernia in these patients is a surgical challenge. Ascites control is the mainstay to reduce hernia recurrence and postoperative complications, such as wound infection, evisceration, ascites drainage, and peritonitis. Intermittent paracentesis, temporary peritoneal dialysis catheter or transjugular intrahepatic portosystemic shunt may be necessary to control ascites. Hernia repair is indicated in patients in whom medical treatment is effective in controlling ascites. Patients who have a good perspective to be transplanted within 3-6 mo, herniorrhaphy should be performed during transplantation. Hernia repair with mesh is associated with lower recurrence rate, but with higher surgical site infection when compared to hernia correction with conventional fascial suture. There is no consensus on the best abdominal wall layer in which the mesh should be placed: Onlay, sublay, or underlay. Many studies have demonstrated several advantages of the laparoscopic umbilical herniorrhaphy in cirrhotic patients compared with open surgical treatment. | Julio CU Coelho Christiano MP Claus Antonio CL Campos Marco AR Costa Caroline Blum | 2016 | World Journal of Gastrointestinal Surgery2016，8，7： | 4 |
| 13 | Totally intracorporeal robot-assisted urinary diversion for bladder cancer(Part 1).Review and detailed characterization of ileal conduit and modified Indiana pouch显示文摘Objective:To review the most used robot-assisted cutaneous urinary diversion(CUD)after radical cystectomy for bladder cancer and create a unified compendium of the different alternatives,including new consistent images Methods:A non-systematic review of the literature with the keywords“bladder cancer”,“cutaneous urinary diversion”,and“radical cystectomy”was performed.Results:Twenty-four studies of intracorporeal ileal conduit(ICIC)and two of intracorporeal Indiana pouch(ICIP)were included in the analysis.Regarding ICIC,the patients’age ranged from 60 to 76 years.The operative time to perform a urinary diversion ranged from 60 to 133 min.The total estimated blood loss ranged from 200 to 1117 mL.The rate of positive surgical margins ranged from 0%to 14.3%.Early minor and major complication rates ranged from 0%to 71.4%and from 0%to 53.4%,respectively.Late minor and major complication rates ranged from 0%to 66%and from 0%to 32%,respectively.Totally ICIP data are limited to one case report and one clinical series.Conclusion:The most frequent type of CUD is ICIC.Randomized studies comparing the performance of the different types of CUD,the performance in an intra-or extracorporeal manner,or the performance of a CUD versus orthotopic ileal neobladder are lacking in the literature.To this day,there are not enough quality data to determine the supremacy of one technique.This manuscript represents a compendium of the most used CUD with detailed descriptions of the technical aspects,operative and perioperative outcomes,and new consistent images for each technique. | Hugo Otaola-Arca Rafael Coelho Vipul R.Patel Marcelo Orvieto | 2021 | Asian Journal of Urology2021，8，1： | 3 |
| 14 | 青少年和年轻成人先天性心脏病的心理社会远期转归显示文摘目的先天性心脏病(CHD)是一种在全球范围内高发的慢性疾病,通常在出生时或出生前确诊。由于诊断以及早期药物和手术治疗的条件较好,患者的生存率达到90%,并且生存时间不断延长,面临着生活中的各种挑战。该研究探讨了不同人口统计学、临床和心理社会变量对CHD青少年和年轻成人患者的生活质量(QOL)感知、心理社会适应和精神障碍患病率的影响,评估CHD青少年和年轻成人患者的生活质量、心理社会适应和精神障碍发病率,确定哪些变量(人口统计学、临床和心理社会变量)对缓解压力、促进恢复起到积极作用,哪些变量起到不良作用。方法该研究入组了150名CHD患者(男87例,女63例),年龄12~26岁(平均年龄:17.45±3.373岁)。对参与者进行了关于社会支持、家庭教育方式、自我形象、人口统计信息和生理限制等方面的访谈。他们对标准化精神病学访谈(SADS-L)中的问题进行了回答,并填写了自我报告问卷,以进行生活质量(WHOQOL-BREF)和心理社会适应(YSR/ASR)的评估。结果所有参与者精神障碍的终身患病率为18.7%(女性25.4%,男性13.8%)。57.1%的参与者有过留级(平均1.53±0.804年)。与整体葡萄牙人相比,CHD患者的生活质量感知在社会关系、环境、身体和总体方面较好。而女性、学习成绩差、较少的社会支持、复杂性CHD、紫绀型CHD、中重度残留病灶、接受过手术和有生理限制患者生活质量感知较差。除了紫绀,所有这些变量也会引起较差的心理社会适应。结论女性CHD患者及学习成绩差且获得社会支持少的CHD患者的心理社会适应和生活质量较差。 | Maria Emlha Gulmaraes Arelas Catarina I.

| 15 | Current status and future perspectives of radiomics in hepatocellular carcinoma显示文摘Given the frequent co-existence of an aggressive tumor and underlying chronic liver disease,the management of hepatocellular carcinoma(HCC)patients requires experienced multidisciplinary team discussion.Moreover,imaging plays a key role in the diagnosis,staging,restaging,and surveillance of HCC.Currently,imaging assessment of HCC entails the assessment of qualitative characteristics which are prone to inter-reader variability.Radiomics is an emerging field that extracts high-dimensional mineable quantitative features that cannot be assessed visually with the naked eye from medical imaging.The main potential applications of radiomic models in HCC are to predict histology,response to treatment,genetic signature,recurrence,and survival.Despite the encouraging results to date,there are challenges and limitations that need to be overcome before radiomics implementation in clinical practice.The purpose of this article is to review the main concepts and challenges pertaining to radiomics,and to review recent studies and potential applications of radiomics in HCC. | Joao Miranda Natally Horvat Gilton Marques Fonseca Jose de Arimateia Batista Araujo-Filho Maria ClaraFernandes Charlotte Charbel Jayasree Chakraborty Fabricio Ferreira Coelho Cesar Higa Nomura Paulo Herman | 2023 | World Journal of Gastroenterology2023，29，1： | 3 |
| 16 | Pentoxifylline enhances the protective effects of hypertonic saline solution on liver ischemia reperfusion injury through inhibition of oxidative stress显示文摘BACKGROUND:Liver ischemia reperfusion(IR)injury triggers a systemic inflammatory response and is the main cause of organ dysfunction and adverse postoperative outcomes after liver surgery.Pentoxifylline(PTX)and hypertonic saline solution(HTS)have been identified to have beneficial effects against IR injury.This study aimed to investigate if the addition of PTX to HTS is superior to HTS alone for the prevention of liver IR injury. | Vinicius Rocha-Santos Estela RR Figueira Joel A Rocha-Filho Ana MM Coelho Rafael Soraes Pinheiro Telesforo Bacchella Marcel CC Machado Luiz AC D'Albuquerque | 2015 | Hepatobiliary & Pancreatic Diseases International2015，14，2： | 3 |
| 17 | Acute fatty liver of pregnancy associated with severe acute pancreatitis:A case report显示文摘Acute fatty liver of pregnancy is a rare disease that affects women in the third trimester of pregnancy. Although infrequent, the disease can cause maternal mortality. The diagnosis is not always clear until the pregnancy is terminated, and significant complications, such as acute pancreatitis, can occur. Pancreatic involvement typically only occurs in severe cases after the development of hepatic and renal impairment. To date, little knowledge is available regarding how the disease causes pancreatitis. Treatment involves supportive measures and pregnancy interruption. In this report, we describe a case of a previously healthy 26-year-old woman at a gestational age of 27 wk and 6 d who was admitted with severe abdominal pain and vomiting. This case illustrates the clinical and laboratory overlap between acute fatty liver of pregnancy and pancreatitis, highlighting the difficulties in differentiating each disease. Furthermore, the hypothesis for this overlapping is presented, and the therapeutic options are discussed. | Cássio Vieira de Oliveira Alecsro Moreira Julio P Baima Leticia de C Franzoni Talles B Lima Fabio da S Yamashiro Kunie Yabuki Rabelo Coelho Ligia Y Sassaki Carlos Antonio Caramori Ferno G Romeiro Giovanni F Silva | 2014 | World Journal of Hepatology2014，6，7： | 3 |
| 18 | Pentoxifylline 通过 TNF- 合成和 TGF-1 基因表示的下面规定改进肝新生显示文摘 AIM:To investigate the mechanism of pentoxifylline(PTX)improvement in liver regeneration.RESULTS:Rats were randomized into 4 groups:Control rats;Sham-sham-operation rats;Saline-70% hepatectomy plus saline solution;PTX-70%hepatectomy plus PTX.At 2 and 6 h after hepatectomy,aspartate aminotransferase,alanine aminotransferase,tumor necrosis factor(TNF)-α and interleukin-6(IL-6)serum and hepatic tissue levels were determined.Tumor growth factor(TGF)-β1 gene expression in liver tissue was evaluated 24 h after hepatectomy by quantitative reverse transcriptase polymerase chain reaction analysis.Proliferation was analyzed by mitotic index and proliferating cell nuclear antigen(PCNA)staining 48 h after hepatectomy.RESULTS:TNF-α and IL-6 serum levels increased at 2 and 6 h after hepatectomy.At 2 h after hepatectomy serum PTX was reduced but not hepatic levels of TNF-α and IL-6.A decrease in liver TGF-β1 gene expression and an increase in mitotic index and PCNA after hepatectomy were observed in the PTX treatment group in comparison to the saline group.CONCLUSION:PTX improves liver regeneration by a mechanism related to down regulation of TNF-α production and TGF-β1 gene expression. | Rodrigo Bronze Martino Ana Maria Mendona Coelho Márcia Saldanha Kubrusly Regina Leito Sandra Nassa Sampietre Marcel Cerqueira Cesar Machado Telesforo Bacchella Luiz Augusto Carneiro D’Albuquerque | 2012 | World Journal of Gastrointestinal Surgery2012，4，6： | 2 |
| 19 | Beneficial effects of adenosine triphosphate-sensitive K^+ channel opener on liver ischemia/reperfusion injury显示文摘AIM:To investigate the effect of diazoxide administration on liver ischemia/reperfusion injury.METHODS:Wistar male rats underwent partial liver ischemia performed by clamping the pedicle from the medium and left anterior lateral segments for 1 h under mechanical ventilation.They were divided into 3 groups:Control Group,rats submitted to liver manipulation,Saline Group,rats received saline,and Diazoxide Group,rats received intravenous injection diazoxide(3.5 mg/kg) 15 min before liver reperfusion.4 h and 24 h after reperfusion,blood was collected for determination of aspartate transaminase(AST),alanine transaminase(ALT),tumor necrosis factor(TNF-α),interleukin-6(IL-6),interleukin-10(IL-10),nitrite/nitrate,creatinine and tumor growth factor-β1(TGF-β1).Liver tissues were assembled for mitochondrial oxidation and phosphorylation,malondialdehyde(MDA) content,and histologic analysis.Pulmonary vascular permeability and myeloperoxidase(MPO) were also determined.RESULTS:Four hours after reperfusion the diazoxide group presented with significant reduction of AST(2009 ± 257 U/L vs 3523 ± 424 U/L,P = 0.005); ALT(1794 ± 295 U/L vs 3316 ± 413 U/L,P = 0.005); TNF-α(17 ± 9 pg/mL vs 152 ± 43 pg/mL,P = 0.013; IL-6(62 ± 18 pg/mL vs 281 ± 92 pg/mL); IL-10(40 ± 9 pg/mL vs 78 ± 10 pg/mL P = 0.03),and nitrite/nitrate(3.8 ± 0.9 μmol/L vs 10.2 ± 2.4 μmol/L,P = 0.025) when compared to the saline group.A significant reduction in liver mitochondrial dysfunction was observed in the diazoxide group compared to the saline group(P < 0.05).No differences in liver MDA content,serum creatinine,pulmonary vascular permeability and MPO activity were observed between groups.Twenty four hours after reperfusion the diazoxide group showed a reduction of AST(495 ± 78 U/L vs 978 ± 192 U/L,P = 0.032); ALT(335 ± 59 U/L vs 742 ± 182 U/L,P = 0.048),and TGF-β1(11 ± 1 ng/mL vs 17 ± 0.5 ng/mL,P = 0.004) serum levels when compared to the saline group.The control group did not present alterations when compared to the diazoxide and saline groups.CONCLUSION:Diazoxide maintains liver mitochondrial function,increases liver tolerance to ischemia/reperfusion injury,and reduces the systemic inflammatory response.These effects require further evaluation for using in a clinical setting. | Mateus Antunes Nogueira Ana Maria Mendona Coelho Sandra Nassa Sampietre Rosely Antunes Patzina Fabiano Pinheiro da Silva Luiz Augusto Carneiro D'Albuquerque Marcel Cerqueira Cesar Machado | 2014 | World Journal of Gastroenterology2014，20，41： | 2 |
| 20 | What can natural edges of gallery forests teach us about woody community performance in sharp ecotones?显示文摘Aims The diversity and structure of forest edges are a central issue in ecology.However,most studies have focused on anthropogenic for-est edges,being natural ones least understood.We studied the com-munities of shrubs and trees in natural edges of gallery forests with the main goal of learning what are the main factors that shape the structure and diversity of these natural sharp ecotones.Methods We evaluated 10 gallery forest sites,allocating in each of them three 15×20 m plots.The plots were laid out in relatively rectilinear stretches of forest edges,respecting a minimal distance of 10 m between each plot.As they are permanent plots and meant to study eventual fluctuations in the forest-grasslands limits,we allocated the plots with their longest side parallel to the forest edge and covering perpendicularly 5 m of the grassland and 10 m of forest.Inside the plots we identified,mapped and measured all shrub and tree individuals with diameter at breast height(DBH)≥1 cm.Important Findings Although many differences exist among the communities in terms of density and basal area,all of them were highly dense and had relatively low basal areas.In addition,both the number of individu-als and the basal area increased rapidly towards the forest interior.Our results also revealed that the edge communities are composed mainly by small individuals that demand a great amount of light.Both the vertical stratification and the proportion of the functional groups are similar among the sites yet change quickly in the first 10 m of the forest edge.However,the floristic similarities were low among the communities mainly due to the species turnover within each area.Therefore,although the overall structure is constant in the studied edges,the low floristic similarity among them possibly indicates that the species within the same functional groups are sub-stituting each other across the sites.Despite older and seemingly stable,our results showed the gallery forest edges are quite similar to the anthropogenic edges or recent clearings.This points out that,independent of the age,those characteristics are possibly permanent in edges. | Gabriela Aparecida de Oliveira Coelho Marcela de Castro Nunes Santos Terra Hisaias de Souza Almeida Eduardo van den Berg | 2017 | Journal of Plant Ecology2017，10，6： | 2 |
