Nuevos datos sobre los Pamphagidae (Orthoptera, Caelifera) de la Península Ibérica I. Nueva subespecie de Eumigus Bolívar, 1878 de la Sierra de Alcaraz (Albacete, España)

Eumigus punctatus calarensis, a new subspecies of Pamphagidae, is described from Sierra de Alcaraz, in Albacete province (Spain), and its characteristics are discussed. We present data about its sound production and acoustic signals. New data on other species of Pamphagidae are given; including discussion of the taxonomic status of Acinipe mabillei, its account as valid species is proposed.

LAS TAXOCENOSIS DE ACRÍDIDOS (ORTHOPTERA,ACRIDIDAE) DE LOS SISTEMAS MONTAÑOSOS DE LA PENÍNSULA IBÉRICA. SU UTILIDAD COMO ELEMENTOS BIOGEOGRÁFICOS.

The study of acridids’ taxocenosis of eleven mountains on the Iberian Peninsula has allowed to stablish three groups of mountains: Atlantic, Ibero-Continental and Ibero-Mediterranean. Thus, it has been confirmed its usefulness as biogeographical elements even in restricted areas.El estudio de las taxocenosis de acrídidos de once sistemas montañosos de la Península Ibérica ha permitido establecer tres grupos de sistemas montañosos: atlántico, ibérico-continental e ibérico-mediterráneo, confirmando su utilidad como indicadores biogeográficos incluso en áreas restringidas

Estrogen-related genes and postmenopausal osteoporosis risk

Background To date, more than 150 candidate genes related to osteoporosis have been described, but osteoporosis has increasingly been considered a polygenic disease modulated by environmental factors. It is thought that osteoporosis predisposition, pathology, and treatment response depend on the interaction between different genes or between genes and environmental factors. Objective The aim of this study was to evaluate the relationship between the presence of single nucleotide polymorphisms (SNPs) in the estrogen metabolic pathway and the development of osteoporosis and to determine whether this relationship is monogenic or whether interactions between genes exist. Materials and methods A multicentric study with 1980 postmenopausal Spanish women in fi ve Spanish communities was conducted. The women completed a specifi c questionnaire that inquired about risk factors for osteoporosis. Data on participants ’ bone mineral density were obtained with dual-energy X-ray densitometers, and genetic data were obtained from frozen peripheral blood. Results The digenic protection combinations indicated involvement of the wild-type genotype (WT) of the 3 UTR marker for the CYP19A1 gene, the IVS4 marker of the same gene, and the BMP15 and FSHR genes. Among patients who carried two or more of the genotypes considered ‘ risky ’ , the triple combination among markers of the ESR2 and NRIP1 genes with any of the two mutations of the analyzed markers of the BMP15 gene gave a mean T -score value of 2.32 0.91 ( p 0.02). Conclusion Variants of the new candidate genes ( NRIP and BMP15 ) can predispose patients to osteoporosis

Phylogenetic prospecting for cryptic species of the genus Merluccius (Actinopterygii: Merlucciidae).

Hakes of the genus Merluccius include 11 valid species as well a number of rare morphotypes suspected to be “cryptic species”. Concatenated nucDNA ITS1-rDNA and mtDNA cyt b sequences plus nested ITS1Nes sequences allowed to ascribe 14 specimens of nine rare morphotypes from the South Pacific and the South Atlantic to the phylogenetic backbone of this genus. Bayesian analyses pointed to M. bilinearis and M. albidus as the oldest species of the genus and the New World cluster, respectively. The phylogenetic status of M. angustimanus from the upper Gulf of California suggests its hybrid origin between M. gayi and M. productus from about 0.25 MYA, although an ever since confinement of a subset of those species cannot be ruled out. The molecular phylodiagnostic test suggests a common origin of all rare morphotypes and the absence of cryptic hake species in the Southern Cone. The molecular background of the morphotypes distributed between the Western Pacific South of New Zealand and the western Atlantic South of Argentina is compatible with their hybrid origin between M. gayi and both, M. australis or M. hubbsi, respectively.This research was partially supported with the project LETSHAKE (AGL2013-4846-R) co-funded by MINECO (Ministerio Español de Economía y Competitividad) and EU-FEDER to M.P. as well as with grant (IN607B 2018/14) to M.

Conservation of limpet populations: a heavily exploited resource in Azores, NE-Atlantic

10th International Temperate Reefs Symposium, The University of Western Australia, 12-17 de janeiro.Limpet harvesting in Azores (NE Atlantic) has been taking place probably since the islands were first colonized in the XV century. Limpet species are highly exploited and populations from most islands have declined steadily bringing about catastrophic effects on coastal communities. Despite their economic importance limpets are also ecologically key species and require prioritizing conservation strategies. Patellid limpets are broadcast spawners which go through a planktonic larval stage in their life cycle. They are benthic as adults and the larva is the only phase during their life-cycle which has the ability to disperse over assumed large spatial distances. However, there is now mounting evidence that gene flow between islands and mainlands can be low, even for species with a relatively long planktonic larval stage. Low levels of larval exchange may thus limit the success of conservation objectives expected upon migration and recruitment. In dispersive isolated oceanic islands such as the Macaronesian Islands, the Azores Archipelago in particular, is not clear whether limpet populations from different islands form a single meta-population or, in contrast, populations on each island are isolated from the rest. Knowledge on this scenario is crucial for the management and conservation of exploited populations of limpets. Here we have developed and described species-specific multiplexed microsatellite markers for the limpets Patella candei and Patella aspera using whole genome shotgun 454 sequencing. These genetic tools have allowed the study of the population genetic structure and evolutionary history of patellid species in the archipelago of Azores. Genetic studies, alongside with biological, ecological and oceanographic information, represent an important contribution for the understanding of population dynamics by allowing testing hypothesis about larval dispersal patterns, recruitment and life history traits, population connectivity, genetic diversity, and population equilibrium

ESTUDIO PRELIMINAR DE LA ENTOMOFAUNA URBANA EN LA REGIÓN DE MURCIA (SE. ESPAÑA)

The domestic fauna of Corvera, village of Murcia province (SE Spain) has been studied in eleven housings. Samplings, using sticky traps, were carried out from November 2002 to October 2003. 21 arthropod orders, belonging to Chaelicerata, Crustacea, Myriapoda and Hexapoda, have been collected. Results show higher abundance and diversity of peridomestic fauna than domestic one. On the other hand, some differences respect to the abundance and appearance frequency of several groups can be observed. This aspect seems to be due to the structural characteristics of the studied village and the biogeographic area to which it belongs.Se ha estudiado la fauna doméstica de once viviendas ubicadas en Corvera, pedanía de Murcia (SE. España). Los muestreos se realizaron desde noviembre de 2002 hasta octubre 2003, utilizando trampas adhesivas. Se han capturado representantes de 21 órdenes de Artrópodos repartidos entre Quelicerados, Crustáceos, Miriápodos y Hexápodos. Los resultados obtenidos muestran un mayor número de ejemplares y de órdenes de la fauna peridoméstica frente a la doméstica. Por otro lado se observa una serie de diferencias en cuanto a la abundancia y frecuencia de ciertos grupos, lo que parece deberse a las características biogeográfi cas de la zona y las estructurales de la población muestreada
