“…At the same time, we found no reduction in microsatellite diversity in the urban populations, providing no evidence for genetic bottlenecks and suggesting that limited MHC diversity of urban coots could reflect adaptive processes (Pikus et al, 2021). It remains to be tested whether parasite pressure is reduced in urban coot populations, but the prevalence of different parasite groups (cestodes, trematodes, chewing lice) was reported to be extremely high (80%-100%) in non-urban coot populations (Yakovleva et al, 2021;Ziani et al, 2020). Many other zoonotic and vector-borne pathogens (e.g.…”

Genes of the major histocompatibility complex (MHC) encode antigen‐binding molecules and are an integral part of the acquired immune response of vertebrates. In general, high individual MHC diversity is expected to increase fitness by broadening the spectrum of pathogens recognized by the immune system, in accordance with the heterozygote advantage mechanism. On the other hand, the optimality hypothesis assumes that individuals with optimal (intermediate), rather than maximum, diversity of the MHC will achieve the highest fitness because of inherent costs associated with expressing diverse MHC alleles. Here, we tested for associations between individual diversity of the MHC class I and class II genes (binding antigens of intra‐ and extracellular pathogens respectively) and a range of fitness‐related traits (condition, ornament expression and reproduction) in an urban population of the Eurasian coot Fulica atra. Contrary to our expectation, we found that high within‐individual allelic diversity of MHC genes (both class I and II) was associated with poorer condition (lower blood haemoglobin concentrations), weaker expression of the putative ornament (smaller frontal shield), later onset of breeding and smaller clutches. An analysis of functional MHC allele clusters (supertypes) provided further support for negative associations of MHC diversity with phenotypic quality and reproductive performance, but most of these relationships could not be explained by the presence of specific maladaptive supertypes. Finally, we found little empirical support for the optimality hypothesis in the Eurasian coot. Our results suggest that the costs of high MHC diversity outweighed any benefits associated with broad MHC repertoire, which could be driven by depauperate pathogen diversity in an urban landscape. To the best of our knowledge, this is one of the first studies providing consistent evidence for negative associations of MHC diversity with a range of fitness‐related traits in a natural avian population.

“…In the context of Algeria, studies specifically focusing on the ectoparasites of water birds are relatively recent. Only a few species have been investigated, including the common coot Fulica atra (Rouag-Ziane et al 2007), the Common Moorhen Gallinula chloropus (Ziani et al 2021), the greater flamingo Phoenocopterus roseus (Touati and Samraoui 2013), the glossy ibis Plegadis falcinellus (Touati et al 2015), the little egret Egretta garzetta (Blagoveshtchensky 1940;Temimi et al 2017), and the White Stork Ciconia ciconia in urban and natural areas (Bouguessa-Cheriak et al 2017) (Table 1). These studies highlight the limited scope of research conducted on water bird ectoparasites in Algeria and demonstrate the need for further investigations to expand our knowledge in this area.…”

The Black-headed Gull, Chroicocephalus ridibundus Linnaeus, 1766, is a migratory bird that winters along the entire Algerian coast and is considered a protected species. In this study, we report the first-ever collection and identification of ectoparasites from Black-headed Gulls in the province of Boumerdes, Algeria. From October and November of 2020 and 2021, a total of 45 live Black-headed Gulls were captured using modified Bal-chatri traps and examined for the presence of ectoparasites. The results revealed a total of 3537 ectoparasite specimens, 264 of which belonged to Phthiraptera and 3273 to Acari. Within Phthiraptera, two species from the suborder Ischnocera were identified: Saemundssonia lari Fabricius, 1780, with a prevalence of 62.22%, and Quadraceps punctatus Burmeister, 1838, with a prevalence of 93.33%. Additionally, one species from the suborder Amblycera, Actornithophilus piceus lari Packard, 1870, was found with a prevalence of 86.66% and the lowest mean intensity with the value of 0.90. As for Acari, Zachvatkinia larica Mironov, 1989, was the most common with a prevalence of 71.11% and the highest mean intensity value of 102.28. Notably, all the recorded parasite species found in the Black-headed Gull in this study are reported in Algeria and in North Africa for the first time. The Pearson’s correlation test indicated a significant difference in parasite infestation of the gull population (r = 0.716; p = 0.046).
