Zengwun estuary in Taiwan is a key habitat for the endangered black-faced spoonbill (Platalea minor), a piscivorous migratory bird. In the winters 2011-2012 and 2012-2013, the percentages were nearly half of that in 2007-2008 (65.5% and 51.1%). To find the reasons of the decline of the habitats is important for the preservation of the endangered bird. So, we used an unsupervised classification method to analyze high spatiotemporal satellite images from FORMOSAT-2 from 2004 to 2013, and found that the quality of spoonbill habitats has deteriorated. The deterioration mainly caused by many of the fishponds there, changing the raised fish from milkfish to grouper fish for the purpose of business benefit in recent 3 years. The water depth in the fishponds, which raised milkfish, used to be kept below 30 cm for the convenience in harvesting in winter. Besides, they left the uneconomical small fish behind in the ponds, which provided the black-faced spoonbills good places to forage. However, after the fishponds were changed to raise grouper fish, it not only made the small fish no more exist in the ponds, but also the developing engineering to deepen the fishponds made the trees around these ponds been cleaned. These trees could have provided shields for the black-faced spoonbills against chilly wind. As a consequence, these changes have substantially reduced the agreeable region where the depth of water should be less than 30cm for black-faced spoonbill to forage and inhabit. New reserves for spoonbills have been established recently in Taiwan. Nevertheless, a detailed plan for maintaining food resources for spoonbills as well as returning them habitats, must be implemented immediately.

Introduction:?An instrumental extraction is performed in order to shorten the phase of expulsion of the fetus outside the maternal pelvic pathway, when there is a suspected fetal state or a defect in progression of the fetal mobile. It can be responsible for immediate or late maternal complications, which are not specific because they can occur after a normal delivery. The objectives of this work are to describe the epidemiological-clinical and prognosis aspects of deliveries assisted by instrumental extractions in a reference maternity unit in Dakar.?Materials and Methods:?This was a retrospective, descriptive and analytical study between January 1, 2017 and December 31, 2017, a period of 12 months at the maternity ward of the Nabil Choucair Health Center. The collection was carried out using the survey form completed on the basis of the analysis of the files, the delivery register and the anaesthesia register of the operating room. The parameters studied were about socio-demographic?characteristics, indications and prognosis. The data entry was carried out using the Sphinx version 5 software and the data analysis using the Epi info version?3.5?software. Results:?During the period of our study, we collected 94 instrumental?extractions. The frequency of instrumental extractions was?1.7%. The average age of the patients was 25 years with extremes of 16 to 43 years old. The average parity was 1 with extremes 1 to 6. Among parturient women, 12?patients (12.8%) had a history of suction cup, two (2.1%) had received forceps and three (3.2%) had a cesarean section. The average gestational age was 39 Weeks of Amenorrhea (WA), the average uterine?height was 32?cm, fetal heart sounds were normal in 98% parturient’ cases. The vaginal?touch had found a fully dilated cervix, a rupture of the amniotic sac with clear amniotic?fluid in 98% of parturient women and a fetus with an anterior left iliac occipito topin 69.4% of cases. The pelvis was clinically normal in all parturient wo
