    Results of the eighth winter waterbird census in Libya in January 2012
    Proceedings of the 2nd International Congress “Speciation and Taxonomy”, May 16th-18th 2014, Cefalù-Castelbuono (Italy)

    ABSTRACT
    After sporadic observations and reports on Libyan birds during the last century, a regular census of wintering birds at Libyan coastal wetlands started in January 2005. Results of each winter census till 2011 have been published. The survey of 2012 was carried out by the authors of the present paper. The general aim was to continue the census of wintering waterbirds in Libya, despite the difficulties that faced the team after the War of Liberation, and the fact that certain areas, very important for birds, have been declared military areas. A total of 29,314 individuals belonging to 69 waterbird species was counted. Comparatively, the number of sites covered in 2012 was less than that in previous years of the survey. The majority of individuals counted belong to seven gull species. This survey also observed a total of 56 individuals of Aythya nyroca Guldenstadt, 1770, a Near Threatened species, as well as, for the first time, a single individual of Canada Goose Branta canadensis (Linnaeus, 1758) in eastern Libya.

    The diversity of wild animals at Fezzan Province (Libya)
    Proceedings of the 2nd International Congress “Speciation and Taxonomy”, May 16th-18th 2014, Cefalù-Castelbuono (Italy)

    ABSTRACT
    Fezzan province (Libya) is a segment of true Sahara, is characterized by diverse habitats that are utilized as shelters and feeding ground for many desert wildlife species. Oases with water table near the surface are the most prominent feature in the Libyan desert. The diversity in habitats resulted in diversity in wildlife, as well as the plant cover (trees and bushes) is the most effective factor for the existence and the abundance of wild animals, in particular bird species. This study observed many species of reptiles, birds and mammals. In the study is also reported the rock hyrax Procavia capensis Pallas, 1766 (Hyracoidea Procaviidae) a rare and endemic species at the area.

    Ecological importance of Al-Gara Marine Protected Area (MPA) in the eastern part of Sirte Gulf, Libya
    https://doi.org/10.31396/Biodiv.Jour.2024.15.4.765.771

    ABSTRACT
    Islands are important ecosystems for biodiversity and also represent a refuge area for many species, often threatened, that live on them. The Libyan coastline is characterized by the presence of many islands. In term of biodiversity hotspots, eight important sites have been identified in Libya. Al-Gara is one of these sites as important island ecosystem; it was declared as Marine Protected Area (MPA) according to the resolution of the Minister of Environment No. 272 of 2021, which includes the area surrounding the island. This island is annually hosting the biggest colony of the Lesser crested tern Thalasseus bengalensis (Lesson, 1831), the main breeding site for this species in the Mediterranean, and it is also a breeding ground for the European shag Phalacrocorax aristotelis (Linnaeus, 1761). Fieldwork was conducted on February and May 2023. Eleven (11) species of Macrophytes have been collected during this study, 17 species of Molluscs, four Crustaceans and 16 Fish species including five non indigenous species. Illegal fishing and illegal fishing gears, fishing in critical ecosystems, invasive species, overfishing and oil pollution are the most important threats to Al-Gara MPA.

    National Inventory and status of Chondrichthyes in the South Mediterranean Sea (Libyan Coast)
    https://doi.org/10.31396/Biodiv.Jour.2023.14.3.459.480

    ABSTRACT
    Libya has the longest coastline in the southern Mediterranean Sea, which is distinguished by the diversity of habitats and marine species; chondrichthyans are one component of this diversity. They are vulnerable to overexploitation due to their reproduction pattern and are generally regarded as a few resilient species. A total of 59 Elasmobranchs belonging to 24 families have been recorded along the Libyan coast out of about 88 documented species (FAO, 2018a; FAO, 2018b; Serena and Barone, 2023). Most of these species breed in the central part of Libya (Gulf of Sirt). A total of 8 elasmobranchs species were identified as by-catch in the Libyan tuna longline fishery (Prionace glauca, Isurus oxyrinchus, Odontaspis ferox, Alopias superciliosus, Heptranchias perlo, Mustelus mustelus, Pteroplatytrygon violacea and Carcharhinus plumbeus). The Tiger shark, Galeocerdo cuvier, is the most recently documented species on the western coast of Libya. This study provides some important information on elasmobranchs in Libyan waters to fill the gap of knowledge about these species in Libya and the southern Mediterranean regions.

    First record of White-faced Whistling-Ducks Dendrocygna viduata (Linnaeus, 1766) (Aves Anatidae) in Libya
    https://doi.org/10.31396/Biodiv.Jour.2022.13.4.813.816

    ABSTRACT
    In 24th May 2022, the presence of one adult specimen of White-faced Whistling-Duck Dendrocygna viduata (Linnaeus, 1766) (Aves Anatidae) was recorded in the sewage treatment lagoon of Al-Saket, in Misrata city about 200 km east to Tripoli (32°19’11.0”N 15°00’48.3”E), Libya. It was found swimming on water surface of the lagoon. Dendrocygna viduata breeds in sub-Saharan Africa and much of South America and is considered as gregarious and vagrant species. This is the first record of D. viduata in Libya that requires further confirmation as only one specimen has been observed and being a duck subject to human breeding.

    The role of constructed wetlands in the conservation of biodiversity: a case study on birds diversity in Al-Hadba treatment plant, Tripoli, Libya
    https://doi.org/10.31396/Biodiv.Jour.2022.13.3.627.639

    ABSTRACT
    Urbanization as a result of human population increase has led to the depletion of natural resources and the destruction of natural wetlands. In contrast, the establishment of treatment and purification of plants has led to the creation of new wetlands (constructed wetlands). Although these new ecosystems established for the treatment of municipal wastewater, and subject to operational and maintenance disturbances, many studies have demonstrated that numbers of bird species using such sites are reasonably higher than expected. The present study has investigated the role of Al-Hadba treatment plant in the conservation of biodiversity and the diversity of birds in particular. This paper emphasizes that, this area is one of the stopover sites for migrating birds, especially aquatic birds, ducks and long-legged waders. A total of 74 species were recorded during the period of study. Moreover, this study observed the breeding of four species; Marbled Teal Marmaronetta angustirostris, Cattle egret Bubulcus ibis, Moorhen Gallinula chloropus, Black-winged stilt Himantopus himantopus. Some factors such as drought, predation and disturbance were affecting the abundance of individuals at the study area.
