Dr. Abdulmula Abdumagid Alhadi Hamza

تحصل الدكتور عبدالمولى عبدالمجيد حمزة على الدرجة الجامعية بكالوريوس علم الحيوان من كلية العلوم جامعة طرابلس في العام 1994، والتحق بالعمل كباحث في ادارة المحافظة على الطبيعة بالهيئة العامة للبيئة (وزارة البيئة حاليا) في العام 1997. والتحق ببرنامج الماجستير في علم الحيوان اثناء عمله وتحصل على درجة الماجستير في علم الحيوان العام 2004، وكانت دراسته عن بيئة بطنقدميات المياه العذبة في عين تاورغاء وقنواتها وتأثير الخواص الكيميائية والفيزيائية لمياه العين على تلك الانواع. في نفس العام التحق بجامعة ليدز بالمملكة المتحدة بمنحة من المجلس الثقافي البريطاني بطرابلس، وانجز درجة الماجستير Master of Research في التنوع البيولوجي والمحافظة على الطبيعة، وشملت دراسته هناك فصلين الاول معملي عن سلوك الجمود في اسماك الجوبي Poecilia reticulata بعد تعرضها للطيور المفترسة، ودراسة ميدانية عن تأثير نوعية القاع وتركيبته على نوع وحجم الاسماك في نهر الوارف ببريطانيا. وبعد عودته الى ليبيا ساهم في اطلاق العديد من البرامج الوطنية الخاصة بمسوحات الطيور المائية المهاجرة، والاعشاب البحرية وتوزيع فقمة البحر المتوسط بالسواحل الليبية، كما أسس البرنامج الليبي لحماية السلاحف البحرية https://www.facebook.com/LibSTP/ ، وصدرت له العديد من الاوراق العلمية والتقارير الفنية. وفي العام 2008 تحصل على منحة لدراسة الدكتوراة في جامعة هل البريطانية، حيث كانت رسالته للدرجة الدقيقة بعنوان Breeding ecology, migration and population genetics of lesser crested terns Thalasseus bengalensis emigrata وشملت دراسة تفصيلية لبيئة التكاثر وسلوك الهجرة وعلم الوراثة المجتمعي لطيور الخرشنة المتوجة الصغيرة التي تعشش بمناطق محددة من الساحل الليبي، ولا تتواجد في اي ساحل متوسطي اخر. في العام 2014 التحق الدكتور حمزة بكلية العلوم البحرية والبيئة بجامعة ترينغانو الماليزية، ليعمل كأستاذ مساعد في الجامعة ويدرس فيها مقررات عديدة مثل علم الفقاريات البحرية، وعلم البيئة البحرية، والتنوع البيولوجي البحري، وقضايا بيئية عالمية وغيرها، اشرف خلالها على 30 طالب بكالوريوس وساهم في الاشراف الاكاديمي على عدة طلاب دراسات عليا في الماجستير والدكتوراة. وعاد في 2021 الى سابق عمله بوزارة البيئة الى ان انتقل للعمل بقسم الاحياء بجامعة طرابلس استاذا لمواد التشريح المقارن للفقاريات وعلم الفقاريات.

ABSTRACT: Marine turtles have been traditionally considered model organisms to study sex-biased behaviour and dispersal. Although female philopatry has been identified in the loggerhead turtle, with adult females returning to specific locations to nest, studies on the philopatry and breeding migrations of males remain limited. In this study we analysed 152 hatchlings using 15 microsatellite markers. Each individual came from a different nest from samples taken at 8 nesting grounds in the Mediterranean. Our results revealed the existence of 5 genetically differentiated units, mostly due to restricted gene flow for both sexes. This supports existing satellite tracking studies that suggest that mating occurs close to nesting grounds in this region. The 5 management units identified within the Mediterranean included nesting grounds from (1) Libya and Cyprus, (2) Israel, (3) Lebanon, (4) Turkey and (5) Greece. The genetic similarity between distant nesting areas (i.e. Libya and Cyprus) suggests the presence of a more complex pattern of breeding behaviour. Three possible hypotheses, that remain to be tested in future studies, could explain this result: (1) mating might take place in common foraging grounds; (2) mating could occur en route while migrating to/from the breeding grounds; or (3) recent colonisation events could connect the 2 nesting grounds. Overall, our work suggests that widespread male-mediated gene flow between loggerhead nesting grounds is likely to have been previously overstated although opportunistic breeding patterns might connect some widely separated areas.

Hamza, A., & Ho, W. C. (2020). Updates on seabirds of the northern Seribuat Islands, Pahang, Malaysia. Marine Ornithology, 48, 1-7.

Because of a lack of systematic surveys since the 1950s, information on seabird diversity and the status of seabird colonies along the east coast of Peninsular Malaysia is mostly outdated. The Seribuat Archipelago is composed of many islands, which are located off Pahang state in the north and Johor state in the south. The northern section of the archipelago was surveyed during July-September 2017 to document active seabird colony sites and to assess species richness and the potential threats facing these colonies. Seven islands were found to host significant numbers of terns (Black-naped Terns Sterna sumatrana, Bridled Terns Onychoprion anaethetus, Greater Crested Terns Thalasseus bergii, Lesser Frigatebirds Fregata ariel, and other bird species. We provide details of each site and its suitability for seabirds. Pulau Labas and Pulau Tokong Bahara have the highest species richness (five species each) followed by Pulau Tokong Burung and Pulau Gut (four species each). Tokong Burung (made up of three islands) hosts the largest colony of Bridled Terns in the region, with more than 10 000 pairs estimated, making it one of the largest colonies of the species in Southeast Asia. Egg harvesting by local fishermen, human disturbance, marine litter, and oil pollution are the main threats to seabirds in the Seribuat Archipelago. We make recommendations regarding measures needed for further protection of the area.

Malaria in Illegal Immigrants in Southern Libya

Background: Libya has been malaria-free since 1973. The risk of malaria re-introduction to Libya is increasing because of the increase in imported malaria cases due to immigration to Libya from countries where malaria is endemic. Cases are mainly due to P. falciparum and Sub-Saharan Africa is the most common origin. This study was conducted to investigate the prevalence of malaria positive cases among illegal immigrants in the southern region of Libya. Methods: A prospective, observational, multi-center study was conducted. Three hundred and three illegal immigrants from 12 different countries were included. Enzyme-linked immunosorbent assay was used to detect the presence of serum malaria antibodies. Results: A total of 303 immigrants were included in the study with mean age of 25.78±5.92 years. Of them, 195 tested positive for malaria antibodies. Two hundred and sixty nine of the participants came from Brak Al-Shati, 16 from Sebha and 18 from Bergan centers, with 175, 15 and 5 positive cases, respectively. Most of the positive cases (172) arrived in Libya within 1-10 months. The highest number of positive cases (70) came from Ghana followed by (40) from Niger and (39) from Bangladesh. Conclusions: Illegal immigration is a major malaria re-introduction route. The issue of illegal immigration have to be treated urgently to stop the huge influx of illegal immigrants and increase the surveillance activities of infectious diseases in order to keep Libyan territories as a malaria-free lands. Key words: Illegal immigration, Malaria, Libya.
