During this study, Coccinellidae were collected and observed at 25 sites located along the coast and inland of the island of Fuerteventura during 2016 and 2017. A total of 2825 Coccinellidae specimens belonging to 22 species was recorded, of which 11 species are newly recorded from Fuerteventura. In the case of three species taxonomical decisions are proposed. Scymnus incisus (Har. Lindberg, 1950) is transferred to the genus Nephus Mulsant and placed in the nominate subgenus as Nephus (Nephus) incisus (Har. Lindberg, 1950), comb. nov. Scymnus medanensis Eizaguirre, 2007, is redescribed and placed in the subgenus Pullus Mulsant. Coccinella algerica Kovář, 1977, is synonymized with Coccinella septempunctata Linnaeus, 1758, syn. nov. We propose retaining the taxonomic distinction of the North African and Canarian populations of this species as the subspecies Coccinella septempunctata algerica Kovář, stat. nov. Nephus peyerimhoffi (Sicard, 1923) is deleted from the list of ladybird beetles inhabiting the Canary Islands.

The taxonomic status of Bombus terrestris subspecies is complex and has deep implications in the management of commercial bumblebees for crop pollination as well as in the establishment of appropriate conservation plans. Herein, the complete mitogenome of the endemic Canary Islands subspecies Bombus terrestris canariensis is newly sequenced and compared with available mitochondrial sequences in order to shed light into its taxonomic status. The mitochondrial genome was 17,300 bp in length and contained 37 genes, including 13 protein-coding genes (PCGs), two rRNAs, and 22 tRNAs and a partial sequence of the AT rich control region. The phylogenetic analysis of PCGs of the mitogenome was congruent with its subspecific status and a close relationship with the North African subspecies africanus as previously suggested. The sequencing of the mitogenome of B. t. canariensis provides useful genetic information to study the conservation genetics and genetic diversity of these island bumblebee populations.

The Impact

North African history and populations have exerted a pivotal influence on surrounding geographical regions, although scant genetic studies have addressed this issue. Our aim is to understand human historical migrations in the coastal surroundings of North Africa. We built a refined genome-wide dataset of North African populations to unearth the fine-scale genetic structure of the region, using haplotype information. The results suggest that the gene-flow from North Africa into the European Mediterranean coast (Tuscany and the Iberian Peninsula) arrived mainly from the Mediterranean coast of North Africa. In Tuscany, this North African admixture date estimate suggests the movement of peoples during the fall of the Roman Empire around the fourth century. In the Iberian Peninsula, the North African component probably reflects the impact of the Arab expansion since the seventh century and the subsequent expansion of the Christian Kingdoms. By contrast, the North African component in the Canary Islands has a source genetically related to present-day people from the Atlantic North African coast. We also find sub-Saharan gene-flow from the Senegambia region in the Canary Islands. Specifically, we detect a complex signal of admixture involving Atlantic, Senegambian and European sources intermixing around the fifteenth century, soon after the Castilian conquest. Our results highlight the differential genetic influence of North Africa into the surrounding coast and show that specific historical events have not only had a socio-cultural impact but additionally modified the gene pool of the populations.

Forest Habitats

In March and April of 2014 and 2015, overwintering and post-overwintering assemblages of ladybird beetles were investigated in deciduous (Tilio-Carpinetum) and mixed forest (Querco roboris-Pinetum) patches in a forest complex on the north-western periphery of Warsaw. March samples were collected by sifting forest litter with an entomological sieve, while in April, ladybirds were collected from the vegetation using sweeping net and beating sheet. In both years, mean densities of ladybirds found in March in the two forest types were low, not exceeding 2 individuals/m2. Seven ladybird species were found overwintering in the litter of the deciduous forest and four in that of the mixed forest. Propylea quatuordecimpunctata was the most abundant in both habitats in 2014, while in 2015 in the litter of the deciduous forest Vibidia duodecimguttata predominated. In April, 15 species were recorded in the deciduous forest and 7 in the mixed forest. Scymnus ferrugatus predominated in the former plant community and P. quatuordecimpunctata and Coccinella septempunctata in the latter. Several of the recorded species, such as Clitostethus arcuatus, Scymnus femoralis and S. abietis, have rarely been reported from Poland.

The current study of the North Africans of the Canary Islands during the 16th-18th centuries represents a contribution to the question of the development of the Muslim stereotype in Spain. This population with origins almost exclusively in north-western Africa, an area known at the time as Barbary, was forcibly relocated to the islands. Most of the Old Christians at the moment of the Royal Decree of 1609 expelling of the Moriscos from the Peninsula declared that the Moriscos of the archipelago were good Christians and loyal vassals. The archipelago was hence the only area of the Spanish Crown where they were not expelled. Fear served the monarchies of new emerging modern state to secure power and fashion a proto-national identity that differentiated individuals of different cultures and religions. The Moriscos of the archipelago were therefore throughout three centuries one of the main collectives singled out for religious, political and economic reasons.

Inflammatory Effect

The seeds of Ammodaucus leucotrichus Cosson and Durieu have been used in the North African Sahara as a traditional medicine to treat diabetes. The present study investigates the antidiabetic, antihyperglycemic, and anti-inflammatory properties of the defatted hydroethanolic extract of Ammodaucus leucotrichus (DHEAM). The antidiabetic and the antihyperglycemic studies were assessed on alloxan-induced diabetic with orally administered doses of DHEAM (100 and 200 mg/kg). At the same time, its anti-inflammatory propriety was evaluated by measuring edema development in the Wistar rats paw induced with carrageenan. Treatment of diabetic mice with DHEAM for four weeks managed their high fasting blood glucose levels, improved their overall health, and also revealed an excellent antihyperglycemic activity. Following the anti-inflammatory results, DHEAM exhibited a perfect activity. HPLC results revealed the presence of seven molecules (chlorogenic acid, 3-p-coumaroylquinic acid, gallic acid, ferulic acid, myricetin, quercetin, luteolin). This work indicates that the DHEAM has an important antidiabetic, antihyperglycemic, and anti-inflammatory effect that can be well established as a phytomedicine to treat diabetes.

Sperm Nuclei

Acephalic spermatozoa syndrome (ASS) is a rare but extremely severe type of teratozoospermia, defined by the presence of a majority of headless flagella and a minority of tail-less sperm heads in the ejaculate. Like the other severe monomorphic teratozoospermias, ASS has a strong genetic basis and is most often caused by bi-allelic variants in SUN5 (Sad1 and UNC84 domain-containing 5). Using whole exome sequencing (WES), we investigated a cohort of nine infertile subjects displaying ASS. These subjects were recruited in three centers located in France and Tunisia, but all originated from North Africa. Sperm from subjects carrying candidate genetic variants were subjected to immunofluorescence analysis and transmission electron microscopy. Moreover, fluorescent in situ hybridization (FISH) was performed on sperm nuclei to assess their chromosomal content. Variant filtering permitted us to identify the same SUN5 homozygous frameshift variant (c.211+1_211+2dup) in 7/9 individuals (78%). SUN5 encodes a protein localized on the posterior part of the nuclear envelope that is necessary for the attachment of the tail to the sperm head. Immunofluorescence assays performed on sperm cells from three mutated subjects revealed a total absence of SUN5, thus demonstrating the deleterious impact of the identified variant on protein expression. Transmission electron microscopy showed a conserved flagellar structure and a slightly decondensed chromatin. FISH did not highlight a higher rate of chromosome aneuploidy in spermatozoa from SUN5 patients compared to controls, indicating that intra-cytoplasmic sperm injection (ICSI) can be proposed for patients carrying the c.211+1_211+2dup variant. These results suggest that the identified SUN5 variant is the main cause of ASS in the North African population. Consequently, a simple and inexpensive genotyping of the 211+1_211+2dup variant could be beneficial for affected men of North African origin before resorting to more exhaustive genetic analyses.
