Don In this year’s Tree of the Year article DOUGLAS JUSTICE writes an account of the western red-cedar or giant arborvitae (tree of life), a species of conifers that, for centuries has been central to the lives of people of the Northwest Coast of America. “In a small clearing in the forest, a young woman is in labour. Two women companions urge her to pull hard on the cedar bark rope tied to a nearby tree. The baby, born onto a newly made cedar bark mat, cries its arrival into the Northwest Coast world.

Abstract: Two culturally-significant plants (sweetgrass [ Anthoxanthum nitens ] and beargrass [ Xero - phyllum tenax ]) are used as case studies for investigating methods of restoring plant populations that are adapted to indigenous burning practices without using fire. Reports from tribal members that the plants of interest were declining in traditional gathering areas provided the impetus for research with both species. In both situations, reintroducing large-scale repetitive burning was not feasible. Field studies of planting with cover crops and manually clearing competing shrubs and herbaceous plants are examined, as well as a greenhouse study evaluating the effect of smoke-water on seed germina - tion. -
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.

The Relation of Soil Characteristics to Growth and Distribution of Chamaecyparis Lawsoniana and Thuja,Plicata in Southwestern Oregon
AN ABSTRACT OF THE THESIS OF DAVID KIMBERLY IMPER for the degree of MASTER OF SCIENCE in BOTANY AND PLANT PATHOLOGY presented on ty,.1/(980 Title: THE RELATION OF SOIL CHARACTERISTICS TO GROWTH AND DISTRIBUTION OF CHAMAECYPARIS LAWSONIANA AND THUJA PLICATA IN SOUTHWESTERN OREGON Redacted for Privacy Abstract approved: lkoLltcT B. Zobel Twelve plots at six sites in southwestern Oregon were studied to determine the degree to which various soil characteristics are related to the occurrence and growth of Chamaecyparis lawsoniana and Thu,la plicata. Soil profiles and vegetation were described in each plot, and measurements were made of insolation, soil and litter temperature, creek and groundwater characteristics, and litter accumulation. Growth was estimated by measurement of age, height, DBH, 10-year basal area increment, and foliage elongation between July, 1979, and January, 1980. In July and September, 1979, and January, 1980, mineral soils from the 0-10 cm level were analyzed for pH, moisture holding capacity, loss-on-ignition, and concentra- tions of nitrate, ammonium and total N. Nitrate and ammonium concentrations were also determined in stream and groundwater. In July and January, fine litter was analyzed for pH, nitrate and ammonium. On each sample date, soils and litter were incubated aerobically for five weeks at 28°C to determine their potentialfor ammonification and nitrification.Ammonium was added to some samples before incubation. Total N concentration was determined for individ- ual foliage samples (collected in September) in most plots; foliage and mineral soil samples were composited for each plot and analyzed for P, Ca, K and Mg concentrations.The various soil and other measurements were related to basal area increment by multiple regression analysis. -
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. -

Three ways to contact us: FAX: (303) 621-2864 (24 HRS.) email: [email protected] website: www.alplains.com Dear Growing Friends: Welcome to our 23rd annual seed catalog! The summer of 2012 was long, hot and brutal, with drought afflicting most of the U.S. Most of my botanical explorations were restricted to Idaho, Wash- ington, Oregon and northern California but even there moisture was below average. In a year like this, seeps, swales, springs, vestigial snowbanks and localized rainstorms became much more important in my search for seeding plants. On the Snake River Plains of southern Idaho and the scab- lands of eastern Washington, early bloomers such as Viola beckwithii, V. trinervata, Ranunculus glaberrimus, Ranunculus andersonii, Fritillaria pudica and Primula cusickiana put on quite a show in mid-April but many populations could not set seed. In northern Idaho, Erythronium idahoense flowered extensively, whole meadows were covered with thousands of the creamy, pendant blossoms. One of my most satisfying finds in the Hells Canyon area had to be Sedum valens. The tiny glaucous rosettes, surround- ed by a ring of red leaves, are a succulent connoisseur’s dream. Higher up, the brilliant blue spikes of Synthyris missurica punctuated the canyon walls. In southern Oregon, the brilliant red spikes of Pedicularis densiflora lit up the Siskiyou forest floor. Further north in Oregon, large populations of Erythronium elegans, Erythronium oregonum ssp. leucandrum, Erythro- nium revolutum, trilliums and sedums provided wonderful picture-taking opportunities. Eriogonum species did well despite the drought, many of them true xerics. -

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.
