Differences in semen freezability and intracellular ATP content between the rooster ( Gallus gallus domesticus) and the Barbary partridge ( Alectoris barbara)

This study aimed to compare viability, ATP content, and DNA integrity of rooster ( Gallus gallus domesticus) and Barbary partridge ( Alectoris barbara) fresh and frozen spermatozoa in order to identify factors possibly related to differences in semen freezability. Ejaculates were obtained from March to May by the abdominal massage method from 3 adult roosters and 12 adult Barbary partridges. Semen was frozen with different cryoprotectants using Lake's diluents as a base medium: 1) glycerol 11%; 2) glycerol 11% and trehalose 70 mmol/L; 3) dimethylacetamide (DMA) 6%; 4) DMA 6% and trehalose 70 mmol/L. Both fresh and frozen semen showed a lower viability and higher intracellular ATP concentrations in the Barbary partridge compared with the rooster (P < 0.05). In the Barbary partridge, semen viability after thawing did not differ among the 4 media used, but glycerol showed positive effects in avoiding a significant loss of ATP after thawing, compared with DMA containing media (P < 0.05). On the other hand, in the rooster a higher viability was recorded when semen was frozen in glycerol containing media compared to DMA (P < 0.0001), while ATP values significantly decreased after thawing (P < 0.05) without showing any differences among the semen frozen in the 4 different media. DNA integrity, as evaluated by the comet assay, was assessed only in frozen semen. In the Barbary partridge, mean scored parameter did not differ significantly among semen frozen in the 4 different media. In the rooster DNA fragmentation was higher in DMA ctr medium compared with the other media and with values found in Barbary partridge semen frozen in the same medium (P < 0.001). In both species, the addition of trehalose did not show any positive effects on viability, ATP levels and DNA integrity after thawing. In conclusion, species-related differences in semen features exist between the rooster and the Barbary partridge and the wide variation observed in ATP levels may account for differences in semen freezabililty between the two species.

Current status of the Sardinian partridge (Alectoris barbara) assessed by molecular markers

Four Alectoris species inhabit the Mediterranean area, where they represent important gamebirds subject to human manipulations. The Sardinian partridge is peculiar in Europe, in that it belongs to the African species Alectoris barbara. Nevertheless, no comprehensive study has as yet investigated its genetic status as regards both the extant levels of genetic diversity and the possible contamination due to introgressive hybridization with other Mediterranean species. For the purposes of this study, we analyzed 65 samples of Sardinian partridges, 40 of which came from the wild population and 25 from captive stocks. No one of them showed a mtDNA polymerase chain reaction restriction fragment length polymorphism haplotype assigned to another species than A. barbara, thus, ruling out a possible introgression in the maternal line. In addition, we compared these samples with 94 partridges from other circum-Mediterranean populations using a set of eight chicken (Gallus gallus) microsatellites. A low level of genetic variation was observed in the Sardinian population (H E = 0.310; k AR = 2.69), comparable only to that observed in the Sicilian rock partridge (A. graeca). The comparison with the Tunisian population showed that its present genetic composition is consistent with a historical introduction from North Africa, showing possible effects of a post-introductional genetic drift. Bayesian tests assigned all but one individuals with >90% probability to A. barbara, thus, providing evidence that no or only a few exotic Alectoris genes have introgressed into Sardinian partridges.

Birds and Artisans of the Roman Mosaics of Tunisia: Species, Symbolism and Origins

Abstract: The mosaic pavements of Roman North Africa contain both African and Italian bird species, amongst others, but it was not possible to attribute pavements to mosaicists from either country on the basis of the avifauna depicted. Forty-one species of birds were recorded, the most commonly occurring being the Indian Peafowl Pavo cristatus, Barbary Partridge Alectoris barbara, Pheasant Phasianus colchicus and Mallard Anas platyrhynchos. Birds appear in a variety of ways: representing the seasons, game to be served to guests dining at a banquet, hunting including falconry and disguises, immortality and the gardens in paradise, myth, ritual as well as for decoration. Pavements containing birds spanned the first to the sixth centuries and have been found in twenty-nine locations in Tunisia. El Djem was the third century centre for birds in mosaics, shifting to Carthage and Thuburbo Majus in the fourth, then Tabarka in the fifth, with a notable decline in species diversity. The pavements preserve an ornithological treasure.

Exotic, introduced and invasive avifauna on Tenerife: are these species a serious threat?

I review the exotic avifauna of Tenerife since records began in the late 1980´s and update and analyse the actual status of these bird species by providing new data, from 2005-2006, of the distribution of these apparently selfsustaining populations. A literature search did not make clear how many species are present on Tenerife (range 1-9) and suggested that all introductions to this island were of species from 4 orders (i.e. Galliformes, Columbiformes, Psittaciformes and Passeriformes) belonging to 7 families (Numidae, Phasianidae, Columbidae, Psittacidae, Estrildidae, Fringillidae and Sturnidae). However, only 5 introduced species (Alectoris barbara, Streptopelia roseogrisea, Myiopsitta monachus, Psittacula krameri and Nandayus nenday) belonging to the orders Galliformes, Columbiformes and Psittaciformes show self-sustaining populations on Tenerife today. It is concluded that the introduction process on Tenerife is mainly “accidental” with some voluntary introductions for recreational hunting in the 15th century. All exotic, accidentally introduced, avifauna to Tenerife has always been associated with urban habitats which are suboptimal. Passeriformes appear to find it difficult to become established on Tenerife. Psittaciformes are the most successful order, and need to be monitored and possibly controlled in the near future.

The helminth fauna of the barbary partridge Alectoris barbara in Tenerife, Canary Islands

The helminth fauna of the barbary partridge (Alectoris barbara) in Tenerife Island (Canary Archipelago) was studied from 2001 to 2002, as there were no records of helminths from this host in the Canary Islands. Seven helminth species were identified: two cestodes Choanotaenia infundibulum and Lyruterina nigropunctata, and five nematodes Aonchotheca caudinflata, Baruscapillaria obsignata, Eucoleus annulatus, Ascaridia galli and Heterakis gallinarum. Lyruterina nigropunctata, A. galli and E. annulatus are recorded for first time in A. barbara. An analysis of available data on Alectoris spp. reveals the importance of intermediate hosts such as arthropods and earthworms in the diet of partridges. Terrestrial helminths are dominant species, with monoxenous and heteroxenous species being present in similar numbers in different Alectoris species along their geographical distribution. Helminth species found in Tenerife from A. barbara are poor indicators of the host colonization from North Africa because these helminths are species that are commonly found in fowl with a cosmopolitan distribution.

A new genus and four new species of quill mites (Acari: Prostigmata: Syringophilidae) from phasianid birds (Galliformes: Phasianidae)

A new genus and four new species of the quill mites are described. Galliphilopsis gen. n. (G. francolinus sp. n., type species) differs from the closely related Dissonus Skoracki, 1999 by loss of leg setae dGII, the slightly divergent tips of epimeres I and the stylophore constricted posteriorly. Three new species of the genus Galliphilopsis gen. n. and one new species of the genus Mironovia Chirov and Kravtsova, 1995 are described from galliform birds (Phasianidae) collected at the Museum of Natural History, Wroclaw University (Poland): G. lophurus sp. n. from Lophura leucomelanos, G. bochkovi sp. n. from Tragopan sp. and Alectoris barbara, G. francolinus sp. n. from Francolinus levalliantoides, and Mironovia rouloul sp. n. from Rollulus rouloul.
