An ecological survey of Laro-limicolae in Northeastern Algeria

We conducted an inventory and characterization of Laro-limicolae settlement at three Ramsar sites located in Eastern Numidia (Lake Tonga, Lake Oubeira and El Mellah lagoon) between 2014 and 2016. We identified 27 species belonging to six families, dominated by Scolopacidae (10 sp.) and Laridae (9 sp.) followed by Charadriidae (4 sp.), Recurvirostridae (2 sp.) and for Glareolidae and Haematopodidae families (1sp.) Inventoried species exhibited different phenological status: resident (26%), wintering (44%), migratory breeders (19%) and wintering/breeding (11%). Population analysis showed the presence of protected species such as black-tailed godwit and Northern lapwing. Bird counts showed monthly variations in total abundance and richness, peaking during winter. Highest numbers were recorded in January and lowest numbers in August. Analysis of diversity and equitability indices indicated that maximum values (H’ = 3.01 and E = 0.94) were noted at El Mellah lagoon in November and at Lake Oubeira in June. Our study provides recent and unpublished data on a group of birds that are little- documented for North Africa, particularly for Algeria. Our findings open the way for further, more detailed work on the subject, and may serve to develop action plans for the management and conservation of these bird populations and their habitats.

本团队于2014年至2016年间对东部努米迪亚地区（托恩加湖、乌比拉湖以及梅拉哈潟湖）的拉罗-利米科莱群落进行了清点和描述。共识别出隶属于六个科目的27个物种，其中以鹬科（10种）和鸥科（9种）为主，依次为鹳科（4种）、反嘴鹬科（2种），以及 Glareolidae 和 Haematopodidae 科各1种。记录的物种展现出不同的生态学阶段：留鸟（26%）、越冬鸟（44%）、迁徙繁殖鸟（19%）以及越冬/繁殖鸟（11%）。种群分析显示，存在如黑尾塍鹬和北方鸻等受保护的物种。鸟类计数显示，月度总数和丰富度存在变化，冬季达到峰值。记录的最高数量出现在一月份，最低数量出现在八月份。多样性和均匀度指数分析表明，最大值（H’=3.01和E=0.94）分别出现在梅拉哈潟湖的十一月份和乌比拉湖的六月份。本研究为北非，尤其是阿尔及利亚地区，关于鸟类群体及其栖息地的文献资料相对匮乏的鸟类群体提供了最新且尚未发表的资料。我们的研究结果为该领域的进一步深入研究开辟了道路，并为这些鸟类群体及其栖息地的管理和保护行动计划的制定提供了参考依据。
