Concept of an Active Amplification Mechanism in the Infrared
HYPOTHESIS AND THEORY published: 21 December 2015 doi: 10.3389/fphys.2015.00391 Concept of an Active Amplification Mechanism in the Infrared Organ of Pyrophilous Melanophila Beetles Erik S. Schneider 1 †, Anke Schmitz 2 † and Helmut Schmitz 2*† 1 Institute of Zoology, University of Graz, Graz, Austria, 2 Institute of Zoology, University of Bonn, Bonn, Germany Jewel beetles of the genus Melanophila possess a pair of metathoracic infrared (IR) organs. These organs are used for forest fire detection because Melanophila larvae can only develop in fire killed trees. Several reports in the literature and a modeling of a historic oil tank fire suggest that beetles may be able to detect large fires by means of their IR organs from distances of more than 100 km. In contrast, the highest sensitivity of the IR organs, so far determined by behavioral and physiological experiments, allows a detection of large fires from distances up to 12 km only. Sensitivity thresholds, however, have always been determined in non-flying beetles. Therefore, the complete micromechanical environment of the IR organs in flying beetles has not been taken into Edited by: Sylvia Anton, consideration. Because the so-called photomechanic sensilla housed in the IR organs Institut National de la Recherche respond bimodally to mechanical as well as to IR stimuli, it is proposed that flying Agronomique, France beetles make use of muscular energy coupled out of the flight motor to considerably Reviewed by: Maria Hellwig, increase the sensitivity of their IR sensilla during intermittent search flight sequences.

ABSTRACT MITCHELL III, ROBERT DRAKE. Global Human Health
ABSTRACT MITCHELL III, ROBERT DRAKE. Global Human Health Risks for Arthropod Repellents or Insecticides and Alternative Control Strategies. (Under the direction of Dr. R. Michael Roe). Protein-coding genes and environmental chemicals. New paradigms for human health risk assessment of environmental chemicals emphasize the use of molecular methods and human-derived cell lines. In this study, we examined the effects of the insect repellent DEET (N, N-diethyl-m-toluamide) and the phenylpyrazole insecticide fipronil (fluocyanobenpyrazole) on transcript levels in primary human hepatocytes. These chemicals were tested individually and as a mixture. RNA-Seq showed that 100 µM DEET significantly increased transcript levels for 108 genes and lowered transcript levels for 64 genes and fipronil at 10 µM increased the levels of 2,246 transcripts and decreased the levels for 1,428 transcripts. Fipronil was 21-times more effective than DEET in eliciting changes, even though the treatment concentration was 10-fold lower for fipronil versus DEET. The mixture of DEET and fipronil produced a more than additive effect (levels increased for 3,017 transcripts and decreased for 2,087 transcripts). The transcripts affected in our treatments influenced various biological pathways and processes important to normal cellular functions. Long non-protein coding RNAs and environmental chemicals. While the synthesis and use of new chemical compounds is at an all-time high, the study of their potential impact on human health is quickly falling behind. We chose to examine the effects of two common environmental chemicals, the insect repellent DEET and the insecticide fipronil, on transcript levels of long non-protein coding RNAs (lncRNAs) in primary human hepatocytes. -
Patterns of Woodboring Beetle Activity Following Fires and Bark Beetle Outbreaks in Montane Forests of California, USA Chris Ray1* , Daniel R
Ray et al. Fire Ecology (2019) 15:21 Fire Ecology https://doi.org/10.1186/s42408-019-0040-1 ORIGINAL RESEARCH Open Access Patterns of woodboring beetle activity following fires and bark beetle outbreaks in montane forests of California, USA Chris Ray1* , Daniel R. Cluck2, Robert L. Wilkerson1, Rodney B. Siegel1, Angela M. White3, Gina L. Tarbill3, Sarah C. Sawyer4 and Christine A. Howell5 Abstract Background: Increasingly frequent and severe drought in the western United States has contributed to more frequent and severe wildfires, longer fire seasons, and more frequent bark beetle outbreaks that kill large numbers of trees. Climate change is expected to perpetuate these trends, especially in montane ecosystems, calling for improved strategies for managing Western forests and conserving the wildlife that they support. Woodboring beetles (e.g., Buprestidae and Cerambycidae) colonize dead and weakened trees and speed succession of habitats altered by fire or bark beetles, while serving as prey for some early-seral habitat specialists, including several woodpecker species. To understand how these ecologically important beetles respond to different sources of tree mortality, we sampled woodborers in 16 sites affected by wildfire or bark beetle outbreak in the previous one to eight years. Study sites were located in the Sierra Nevada, Modoc Plateau, Warner Mountains, and southern Cascades of California, USA. We used generalized linear mixed models to evaluate hypotheses concerning the response of woodboring beetles to disturbance type, severity, and timing; forest stand composition and structure; and tree characteristics. Results: Woodborer activity was often similar in burned and bark beetle outbreak sites, tempered by localized responses to bark beetle activity, burn severity, tree characteristics, and apparent response to ignition date. -
Response of Orthoptera Assemblages to Management of Montane Grasslands in the Western Carpathians
Biologia 66/6: 1127—1133, 2011 Section Zoology DOI: 10.2478/s11756-011-0115-1 Response of Orthoptera assemblages to management of montane grasslands in the Western Carpathians Vladimíra Fabriciusová, Peter Kaňuch &AntonKrištín* Institute of Forest Ecology, Slovak Academy of Sciences, Ľ. Štúra 2,SK-96053 Zvolen, Slovakia; e-mail: [email protected] Abstract: Montane grassy habitats in the Western Carpathians are relatively well preserved, maintain high species richness and are often important in accordance to the nature conservation policy in Europe. However, knowledge about the impact of farming on the habitat quality there is rather poor. The influence of various management types (permanent sheep pen, irregular grazing, mowing) on Orthoptera diversity and species determining assemblages of these habitats were analysed on 72 plots in Poľana Mts Biosphere Reserve. Altogether, 36 Orthoptera species (15 Ensifera, 21 Caelifera) were found, whereas the highest number of species was found on plots with irregular grazing (28 species), followed by plots with mown grass (17) and permanent sheep pens (14). All four measures of the assemblages’ diversity confirmed significant differences. Using Discriminant Function Analysis, correct classification rate of Orthoptera assemblages was unambiguous according to the type of management. Each form of the management harboured several characteristic species. Thus implications regarding the biodiversity conservation and grassland management were given.

Bracken Fern (Pteridium Aquilinum (L.) Kuhn) Overgrowth on Dry Alpine Grassland Impedes Red List Orthoptera but Supports Local Orthopteran Beta Diversity
Journal of Insect Conservation https://doi.org/10.1007/s10841-021-00333-8 ORIGINAL PAPER Bracken fern (Pteridium aquilinum (L.) Kuhn) overgrowth on dry Alpine grassland impedes Red List Orthoptera but supports local orthopteran beta diversity Jürg Schlegel1 · Matthias Riesen1 Received: 2 January 2021 / Accepted: 8 June 2021 © The Author(s) 2021 Abstract The native bracken fern (Pteridium aquilinum (L.) Kuhn) has become increasingly invasive in abandoned or undergrazed Alpine grasslands. Bracken stands are generally assumed to be poor in species, but there is still very little information about the impact on the fauna. We recorded Orthoptera communities of 24 sample plots with varying bracken cover. Compared to plots with only sparse or medium bracken cover, species richness was highly signifcantly lower in densely overgrown plots, while the former two did not difer markedly. Multivariate ordination analyses revealed gradients with unequal orthopteran communities, showing distinct patterns of bracken cover clustering. Based on indicator values, 13 of 23 Orthoptera species turned out to be signifcantly or marginally signifcantly associated with a single bracken cover stratum or a combination of two strata, whereby all nine Red List species were primarily restricted to sparse or medium bracken cover. However, some generalist species were found to favor denser bracken stands, such as Tettigonia viridissima, contributing to the local Orthoptera beta diversity. Our data suggest that ongoing rotational sheep grazing with temporary paddocks is regarded as the most preferable management system. However, selected parts of the study area, which have only sparse vegetation and no pressure of bracken or scrub overgrowth, are recommended to be alternately left ungrazed for a few years to allow for the coexistence of diferent successional stages. -

Two genera of pyrophilous jewel beetles (Buprestidae) and one species of the genus Acanthocnemus (Acanthocnemidae) show a highly pyrophilous behaviour. For the detection of fires and for the orientation on a freshly burnt area these beetles have special sensors for smoke and infrared (IR) radiation. Whereas the olfactory receptors for smoke are located on the antennae, IR receptors are situated on different places on the body of the beetles. Keywords: pyrophilous beetles, infrared receptor, smoke receptor Zusammenfassung: “Feuerliebende” (pyrophile) Käfer sind für die Fortpflanzung auf Wald- brände angewiesen. Zwei Gattungen von pyrophilen Prachtkäfern (Buprestidae) und eine Art der Gattung Acanthocnemus (Acanthocnemidae) zeigen ein hochgradig pyrophiles Verhalten. Zur De- tektion von Waldbränden und zur Orientierung auf frischen Brandflächen besitzen diese Käfer spezielle Sensoren für Rauchgas und Infrarotstrahlung. Während die Geruchsrezeptoren für Rauch auf den Antennen lokalisiert sind, befinden sich die IR-Rezeptoren an unterschiedlichen Stellen auf dem Rumpf der Käfer. -
