“…Unfortunately, a lack of detailed information on Mediterranean Yellow-legged Gull movements along the North African coasts and across the Mediterranean Sea prevented us from exploring the cause of differences in morphology. Recently, it has been shown that juvenile Mediterranean Yellow-legged Gulls from Algerian colonies cross the Mediterranean Sea and summer at coastal Spanish areas before returning to North Africa in late autumn and winter (Baaloudj et al 2012). These findings are consistent with those of Pons et al (2004), who found evidence of limited gene flow among Mediterranean Yellow-legged Gull colonies.…”

Discriminant analysis functions have previously been determined for sexing Mediterranean Yellow-legged GullsLarus michahellis michahellis from the western Mediterranean basin. However, data from eastern Mediterranean populations are lacking. In this work, we used morphometric data from a sample of 81 Mediterranean Yellow-legged Gulls (39 males and 42 females) breeding in the Gulf of Gabès in south-eastern Tunisia to (1) determine a discriminant function useful for sex discrimination, and (2) assess the accuracy of previously published functions in sexing Mediterranean Yellow-legged Gulls from our study area. Our results showed marked sexual differences in all morphological measurements, with males being significantly larger than females. The best discriminant function included head length, bill depth and wing length, and accurately classified 93% of sampled birds. We also found that Mediterranean Yellow-legged Gulls from the Gulf of Gabès could accurately be sexed using discriminant functions determined for another North African population, but not with a function determined for a South European population, although distances between sites are almost the same.

“…Whilst the dispersal of some Algerian waterbirds and the connectivity of their habitats have been documented recently (Boucheker et al 2011;Baaloudj et al 2012), much less is known about their ectoparasites and the impact of such parasites and pathogens on population dynamics and dispersal of local birds. Despite increased interest in the role of birds in dispersal of infectious disease vectors (Hubálek 2004;Palomar et al 2012;Arnal et al 2014), there is a paucity of such studies in North Africa (Rouag-Ziane et al 2007;Touati and Samraoui 2013).…”

The aim of this study was to identify the ectoparasite community that may be found on the body of Glossy Ibis chicks Plegadis falcinellus in two Algerian wetlands, Chatt and Lake Fetzara, during the breeding season of 2010. Birds were parasitized by the following chewing lice (Phthiraptera: Amblycera, Ischnocera) species at both study sites: Plegadiphilus plegadis and Colpocephalum leptopygos (both Menoponidae), Ardeicola rhaphidius and Ibidoecus bisignatus (both Philopteridae). In addition, one tick (larva) Ixodes ricinus was also found at Lake Fetzara. All these ectoparasites were recorded in Algeria for the first time. Results showed that chewing lice varied in their spatial distribution at the infracommunity level with some species displaying no microhabitat preferences, whereas others confined themselves to specific body parts of their hosts. The recorded frequency pattern of chewing lice followed the negative binomial distribution.Dviejose Alžyro šlapžemėse (Chatt ir Fetzara ežerai) 2010 metų perėjimo laikotarpiu nustatyta rudojo ibio Plegadis falcinellus jauniklių ektoparazitų bendrijos rūšinė sudėtis. Abiejose vietovėse paukščius parazitavo utėlės Plegadiphilus plegadis ir Colpocephalum leptopygos (Menoponidae), bei Ardeicola rhaphidius ir Ibidoecus bisignatus (Philopteridae). Fetzara šlapžemėje aptikta viena erkės Ixodes ricinus lerva. Visi šie ektoparazitai Alžyre užregistruoti pirmą kartą. Šeimininke utėlės buvo pasiskirsčiusios nevienodai: vienos jų parazitavo tik specifinėse šeimininko kūno dalyse, kitoms mikrobuveinės selektyvumas nepasireiškė. Utėlių pasiskirstymas atitiko neigiamą binominį modelį.

“…Between 2003, Boussedra lost 30% of its area and, if this rate continues unchecked, it will probably face the same fate as other Numidian wetlands which have disappeared over the last two decades (de Bélair & Samraoui 1994). The rate of habitat erosion is alarming because many species rely on the close connectivity of local and regional wetlands (Boucheker et al 2011, Baaloudj et al 2012) and we expect that many species cannot indefinitely sustain the loss of key habitats (Semlitsch & Bodie 1998) that may prove critical to ensure regional persistence through local extinctioncolonization dynamics (Taylor et al 1993, Hanski 1998. Monitoring reed bed species which have been shown to be sensitive to landscape features like area, edge effects and fragmentation (Báldi 1999, Paracuellos 2006, and information on demographic parameters such as breeding success in rapidly deteriorating habitats may inform how waterbirds respond to such environmental changes.…”
