The Monte Desert is characterized by a great diversity of landforms created with fluvial， alluvial which the vegetation patterns are related to. The present work has the following objectives: 1: determine whether topographical attributes， surface characteristics， soil properties and vegetation patterns vary between alluvial landforms， and 2: define whether morphometric， soil and surface properties influence vegetation patterns along alluvial landscape. Morphometric data were obtained by processing a 5 m digital elevation model. The coverage of rock fragments， fine sediments and mulch was quantified. Observations and descriptions of the soil profiles were restricted to the uppermost 50 cm. Vegetation properties were calculated using a Point Quadrat Method. The relationship between variables was evaluated through multivariate statistical analysis. The main results show the presence of 45 plant species distributed in 19 families， where shrubs are dominant. The wind effect， topographic wetness and dissection of the landscape are limiting factors of diversity. The coverage of superficial rock fragments influence vegetation coverage through the distribution and availability of rainwater. Furthermore， the different soil textures reveal that the silt content favors an increase in vegetation coverage. The presence of V horizon could condition the installation and development of vegetation in the early stages of growth.

Introduction: Viral hepatitis B is a public health problem worldwide. The objective of this study was to determine the epidemiological and diagnostic profile of chronic carriers of hepatitis B virus seen for gastroenterology consultations in Parakou, Republic of Benin. Patients and Methods: This was a cross-sectional and descriptive study with retrospective data collection. Patients seen for gastroenterology consultations from January 1, 2017 to June 30, 2021 at the Regional Teaching Hospital of Borgou/Alibori (CHUD-B/A) and having been diagnosed as chronic carriers of hepatitis B virus were included. A minimum initial assessment was required to be included. The minimum sample size was calculated with Schwartz formula. The variable of interest was the detection of HBsAg twice and at least 6 months apart. The other variables studied were sociodemographic, clinical and paraclinical data. The data collected were analyzed using SPSS 17 software. Results: A total of 2786 patients were seen for gastroenterology consultations, including 1126 (40.4%) HBsAg-positive patients. Among them, 417 patients met the inclusion criteria and were the subject of the present study. The average age of the patients was 34.8 ± 10.5 years. Two hundred and forty-seven patients (65.7%) were male, representing a sex ratio of 1.9. The discovery of positive HBsAg status was made during systematic screening in 231 patients (55.4%). Scarifications were noted in 373 patients (89.4%). Asthenia was reported in 184 patients (44.1%). Co-infections with human immunodeficiency virus, hepatitis C and D viruses were 0% (0 in 92), 2.8% (4 in 146) and 14.3% (2 in 146), respectively. During the initial assessment, 274 patients (65.7%) were sero-negative for chronic HBeAg infection, 21 (5%) had clinically significant fibrosis including 16 (3.8%) at the stage of cirrhosis and 7 patients (5.4%) had hepatocellular carcinoma. Conclusion: In Parakou, chronic hepatitis B virus infection is common and affects young pe
