The enigmatic and artificial Protorthoptera is the largest Paleozoic order of Neoptera. Typical hemipteroid head characters (inflated clypeus, styletal mouthparts) are here reported for "Protorthoptera" fossils and linked with the basic venational braces of hemipteroid wings. The "order" is recognized as being mostly composed of extremely primitive hemipteroids. Two new Late Carboniferous gerarid wings are described: Osnogerarus trecwithiensis n.gen., n.sp. from the Westphalian D of Osnabrück, Germany, and Cantabrala gandli n.gen., n.sp. from the Lower Stephanian (Cantabrian) of the Cantabrian Mountains, northwestern Spain. Several ground-plan characters of hemipteroids are described: head with visible segmentation; polyramous thoracic legs bearing exites and with trochanter not fused to prefemur; ovipositor with cutting ridges; the medial wing vein is shown as not the complete media (= M), but only the media posterior (= MP); the arculus is diagnosed as a cross-vein turned into an important brace; two radial sectors (RA and RP) originate separately from the radial basivenale; and the anal brace is formed by AA1. The hemipteroid stem-assemblage comprised (i) the gerarid line (extinct) with a long MP–CuA fusion replacing the arculus (derived) and with a repeatedly forked CuP (primitive), and (ii) the paoliid line with an arculus (a convex mp–cua cross-vein) (primitive) and a simple CuP (derived). The paoliids are the probable ancestors of modern hemipteroids. The Hemiptera (Sternorrhycha + Auchenorrhyncha + Coleorrhyncha + Heteroptera) lost the ScA + vein to a V-shaped notch or a flexion line (synapomorphy). Geraridae, Paleozoic and Recent Insecta, and all Arthropoda have demonstrably polyramous legs in the ground plan. Use of the taxon "Uniramia" is erroneous in every aspect. A new method using major venational braces is offered to define the wings of all higher neopteran taxa and to resolve the uncertain relationships between some modern orders. Polyneoptera (plecopteroids + orthopteroids + blattoids) is a polyphyletic taxon, and should be abandoned. Blattoids are not directly related to orthopteroids, but are the sister-group of hemipteroids + endopterygotes. An updated basic phylogenetic scheme of Neoptera proposed here comprises the following clades: (Pleconeoptera (Orthoneoptera (Blattoneoptera (Hemineoptera + Endoneoptera)))).

The brown bearUrsus arctosL., 1758 population of the Cantabrian Mountains (northwestern Spain) became isolated from other bear populations in Europe about 500 years ago and has declined due to hunting and habitat degradation. At the beginning of the 20th century, the Cantabrian population split into eastern and western subpopulations, and genetic exchange between them ceased. In the early 1990s, total population size was estimated to be < 100 bears. Subsequently, reduction in human-caused mortality has brought about an increase in numbers, mainly in the western subpopulation, likely promoting male-mediated migration and gene flow from the western nucleus to the eastern. To evaluate the possible genetic recovery of the small and genetically depauperate eastern subpopulation, in 2013 and 2014 we genotyped hair and faeces samples (116 from the eastern subpopulation and 36 from the western) for 18 microsatellite markers. Data from the annual count of females with cubs of the year (COY) during the past twenty-six years was used to analyze demographic changes. The number of females with COY fell to a minimum of seven in the western and three in eastern subpopulations in the biennium 1993–1994 and reached a respective maximum of 54 and 10 individuals in 2013–2014. We also observed increased bear dispersal and gene flow, mainly from the western to the eastern subpopulation. Of the 26 unique genotypes detected in the eastern subpopulation, 14 (54%) presented an admixture composition, and seven (27%) were determined to be migrants from the western subpopulation. Hence, the two separated and clearly structured subpopulations identified in the past currently show some degree of genetic admixture. This research shows the partial demographic recovery and a change in genetic composition due to migration process in a population of bears that has been isolated for several centuries.

This study aimed to investigate the seroprevalence of C. burnetii in domestic ruminants, wild ungulates, as well as the current situation of Q fever in humans in a small region in northwestern Spain where a close contact at the wildlife–livestock–human interface exists, and information on C. burnetii infection is scarce. Seroprevalence of C. burnetii was 8.4% in sheep, 18.4% in cattle, and 24.4% in goats. Real-time PCR analysis of environmental samples collected in 25 livestock farms detected Coxiella DNA in dust and/or aerosols collected in 20 of them. Analysis of sera from 327 wild ungulates revealed lower seroprevalence than that found in domestic ruminants, with 8.4% of Iberian red deer, 7.3% chamois, 6.9% fallow deer, 5.5% European wild boar and 3.5% of roe deer harboring antibodies to C. burnetii. Exposure to the pathogen in humans was determined by IFAT analysis of 1312 blood samples collected from patients admitted at healthcare centers with Q fever compatible symptoms, such as fever and/or pneumonia. Results showed that 15.9% of the patients had IFAT titers ≥ 1/128 suggestive of probable acute infection. This study is an example of a One Health approach with medical and veterinary institutions involved in investigating zoonotic diseases.
