Coleópteros y sírfidos saproxílicos (Coleoptera; Diptera: Syrphidae) de las dehesas del oeste ibérico: la Reserva Biológica de Campanarios de Azaba (Salamanca)

Se aporta la relación de especies de coleópteros y sírfidos saproxílicos que habitan en ecosistemas de dehesa del oeste ibérico. Se ha estudiado la Reserva Biológica de Campanarios de Azaba, provincia de Salamanca, designada en 2013 como primera Reserva Entomológica de España por la Asociación española de Entomología. Durante los 19 meses de muestreo se registraron 9.603 ejemplares de coleópteros saproxílicos pertenecientes a 157 especies (40 familias) y 477 ejemplares de sírfidos saproxílicos pertenecientes a 18 especies. Para la recolección del material se utilizaron trampas de emergencia y trampas de ventana. Entre los insectos capturados hay diez especies amenazadas, ya sea a nivel europeo o de España, que, a la vista de los resultados, mantienen poblaciones abundantes en este ecosistema de dehesa del oeste ibérico.

Antropometría, Composición Corporal y Somatotipo de las Patinadoras de Elite en Patinaje Artístico sobre Ruedas: Análisis por Disciplinas

El objetivo de este estudio fue describir y comparar las características antropométricas, composición corporal y somatotipo de patinadoras de patinaje artístico sobre ruedas por categorías (junior y senior) y por disciplinas (individual, parejas y danza). Fueron evaluadas 62 patinadoras profesionales (36 en la disciplina de libre, 13 en danza y 13 en parejas). El análisis estadístico utilizado fue una ANOVA para muestras independientes entre disciplinas, y una T de Student para las categorías (junior y senior). Entre la categoría junior y senior no se han encontrado diferencias estadísticas significativas. Las patinadoras junior presentaron un somatotipo endo-mesomorfo, y las patinadoras senior presentaron un somatotipo mesomorfo balanceado. El somatotipo de las patinadoras de parejas y danza fue el mesomórfico balanceado, y el de las patinadoras de libre fue endo-mesomórfico. Este estudio aporta datos biotipológicos de referencia para la población de elite de patinadoras sobre ruedas.

Description of two cryptic species of Anomala Samouelle (Coleoptera: Scarabaeidae: Rutelinae) from Costa Rica

Two new species of Anomala Samouelle from Costa Rica are described: Anomala moroni new species and A. parvaeucoma new species. Habitus, protibia, distribution map, and male genitalia (aedeagus and endophallus) of each species are illustrated. A key for the dorsally setose species from the Neotropical region is provided.

Saproxylic Beetle Assemblage Selection as Determining Factor of Species Distributional Patterns: Implications for Conservation

The knowledge of the distributional patterns of saproxylic beetles is essential for conservation biology due to the relevance of this fauna in the maintenance of ecological processes and the endangerment of species. The complex community of saproxylic beetles is shaped by different assemblages that are composed of species linked by the microhabitats they use. We evaluate how different the species distribution patterns that are obtained can be, depending on the analyzed assemblage and to what extent these can affect conservation decisions. Beetles were sampled using hollow emergence and window traps in three protected areas of the Iberian Peninsula. Species richness, composition, and diversity turnover were analyzed for each sampling method and showed high variation depending on the analyzed assemblage. Beta diversity was clearly higher among forests for the assemblage captured using window traps. This method collects flying insects from different tree microhabitats and its captures are influenced by the forest structuring. Within forests, the assemblages captured by hollow emergence traps, which collect the fauna linked to tree hollows, showed the largest turnover of species, as they are influenced by the characteristics of each cavity. Moreover, the selection of the forest showing the highest species richness strongly depended on the studied assemblage. This study demonstrates that differences in the studied assemblages (group of species co-occurring in the same habitat) can also lead to significant differences in the identified patterns of species distribution and diversity turnover. This fact will be necessary to take into consideration when making decisions about conservation and management.

Novel antennal lobe substructures revealed in the small hive beetle Aethina tumida

The small hive beetle, Aethina tumida, is an emerging pest of social bee colonies. A. tumida shows a specialized life style for which olfaction seems to play a crucial role. To better understand the olfactory system of the beetle, we used immunohistochemistry and 3-D reconstruction to analyze brain structures, especially the paired antennal lobes (AL), which represent the first integration centers for odor information in the insect brain. The basic neuroarchitecture of the A. tumida brain compares well to the typical beetle and insect brain. In comparison to other insects, the AL are relatively large in relationship to other brain areas, suggesting that olfaction is of major importance for the beetle. The AL of both sexes contain about 70 olfactory glomeruli with no obvious size differences of the glomeruli between sexes. Similar to all other insects including beetles, immunostaining with an antiserum against serotonin revealed a large cell that projects from one AL to the contralateral AL to densely innervate all glomeruli. Immunostaining with an antiserum against tachykinin-related peptides (TKRP) revealed hitherto unknown structures in the AL. Small TKRP-immunoreactive spherical substructures are in both sexes evenly distributed within all glomeruli. The source for these immunoreactive islets is very likely a group of about 80 local AL interneurons. We offer two hypotheses on the function of such structures.

Entwicklung einer mechanisch-verschlussgesicherten Kopplelvorrichtung mit integriertem elektrischen Lademechanismus für Elektroroller

Im Rahmen dieser Bachelorarbeit wurde eine Lösung von einer mechanisch verschlussgesicherten Koppelvorrichtung mit integriertem elektrischen Lademechanismus für Elektroroller entwickelt. Davon bezieht es sich auf die Scooter (E-Fahrrad) von REVOLUZER. Das Ziel ist, dass wenn der Elektroroller aufgeladen wird, der E-Roller auch unter Verschluss gegen Diebstahl geschlossen wird. Gemäß der Aufgabenstellung wurden die technischen Daten von Scooter beherrscht. Ebenfalls wird der Bedarf für das System der Hochschule Anhalt bewertet. Im Folgenden wurde der Stand der Technik von weltweit elektrischen Ladestationen für Zweiräder dargestellt, davon waren der mechanische Diebstahlsicherungsschutz und die elektrische Ladevorrichtung Schwerpunkte. Mit morphologischem Kasten wurden die eigenen Lösungen ausführlich entworfen. Davon sind die entsprechende Darstellung mit Hilfe von CAD Programm (Catia Programm) und mit Werteskala für Nutzwertanalyse und Richtlinie VDI 2225 besser zu analysieren und zu bewerten. Nach der Auswahl aus allen Lösungen wurde Festigkeit für Nutzungstauglichkeit nachgewiesen.

(Table 1) Petrological description and consolidation properties of ODP Site 186-1150 and Hole 186-1151A

In order to determine the shear parameters of the forearc sedimentary strata drilled during Ocean Drilling Program Leg 186, West Pacific Seismic Network, Japan Trench, eight whole-round samples were selected from different depths in the drilled sections of Sites 1150 and 1151. Whereas Site 1150 lays above the seismically active part of the subduction zone, Site 1151 is situated in an aseismic zone. The aim of the triaxial tests was, apart from determination of the static stress strain behavior of the sediments, to test the hypothesis that the static stress strain parameter could differ for each sites. In order to simulate undrained deformation conditions according to the high clay mineral content of the strata, consolidated undrained shear tests were performed in a triaxial testing setup. Measurements of water content, grain density, organic content, and microtextural investigations under the scanning electron microscope (SEM) accompanied the compression experiments. After the saturation and consolidation stages were completed, failure occurred in the compression stage of the experiments at peak strengths of 280-7278 kPa. The stiffness moduli calculated for each sample from differential stress vs. strain curves show a linear relationship with depth and range between 181 and 5827 kPa. Under the SEM, the artificial fault planes of the tested specimen only show partial alignment of clay minerals because of the high content of microfossils.
