Abstract:
Abstract Fresh attacks of Douglas-firs (Pseudotsuga menziesii) by Douglas-fir beetles (Dendroctonus pseudotsugae) were found in a campground that had trees pruned to remove Douglas-fir dwarf mistletoe (Arceuthobium douglasii) infections. All Douglas-firs with a diameter at breast height (dbh) of at least 12.7 cm were examined. Beetle attacks were found on 41% of the pruned trees and 5% of the unpruned trees. Among pruned trees, both the average number of branches pruned and the average dbh were greater in trees attacked by Douglas-fir beetles than in unattacked trees. West. J. Appl. For. 15(1):34-36.

Abstract:
Seedlings of Abies grandis (Dougl.) Lindl. (grand fir), Lithocarpus densiflora (Hook. & Arn.) Rehd. (tanoak), Pinus ponderosa Dougl. ex Laws. (ponderosa pine), Pseudotsuga menziesii (Mirb.) Franco (Douglas-fir), and Arbutus menziesii Pursh (madrone) were planted in mixture and monoculture in soil collected from three adjacent forest sites in southwestern Oregon (a clearcut area, a 25-year-old Douglas-fir plantation, and a mature 90- to 160-year-old Douglas-fir - pine forest) to determine the effect of host tree diversity on retrieval of ectomycorrhizal morphotypes. In this greenhouse bioassay, 18 morphotypes of mycorrhizae were recognized overall from all soils with a total of 55 host-fungus combinations: 14 types with ponderosa pine, 14 with Douglas-fir, 10 with tanoak, 10 with grand fir, and 7 for madrone. Four genus-specific morphotypes were retrieved (three on ponderosa pine and one on Douglas-fir), even in mixture situations, demonstrating selectivity of some fungal propagules by their respective host. Five types were detected on all hosts, but not necessarily in soils from all sites. The remaining nine types were associated with two, three, or four hosts, which indicates a wide potential for interspecific hyphal linkages between trees. More morphotypes were retrieved from the monoculture treatments compared with the mixture treatments, although the differences were not significant. Several examples of acropetal replacement of one fungus by another (interpreted as succession) were recorded on all hosts during the course of the experiment. These results illustrate the importance of different host species in maintaining ectomycorrhizal fungus diversity, especially fungi with restricted host range, and the strong potential for fungal linkages between trees in forest ecosystems.Key words: fungal succession, fungal communities, compatibility, Arbutus menziesii, Pseudotsuga menziesii, Pinus ponderosa, Abies grandis, Lithocarpus densiflora.

Abstract:
Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were grown in the greenhouse in a sterilized mixture of forest soil and vermiculite, which had been inoculated with root fragments from one of six different ectomycorrhizal under story plant species (Arctostaphylos uva-ursi (L.) Spreng, P. menziessi, Salix bebbiana Bebb, Alnus viridis subsp. sinuata (Regel) Ä. Löve & and D. Löve (alder), Betula papyrifera Marsh. (paper birch), Populus tremuloides Michx.) and arbuscular mycorrhizal Calamagrostis rubescens Buckl. (pinegrass) sampled from a dry Douglas-fir forest in the southern interior of British Columbia. The overall objective of the present study was to investigate the inoculum potential of these ectomycorrhizal roots for colonizing Douglas-fir seedlings. A total of seven ectomycorrhizal morphotypes formed on the bioassay seedlings, which were colonized by all treatments except the control. Seedlings growing in soil inoculated with root fragments of Douglas-fir, Arctostaphylos, and paper birch had greater ectomycorrhizal richness and a higher percentage of colonized fine roots relative to the pinegrass and alder treatments. The community of ectomycorrhizal fungi that colonized the bioassay seedlings differed from that associated with some of the same refuge plants assessed in a previously reported field-based study at this site. Different ectomy corrhizal fungal colonization strategies and the retention of refuge plants are discussed in relation to the colonization of outplanted seedlings following clearcutting.Key words: ectomycorrhizae, refuge plants, inoculum potential, soil bioassay, Pseudotsuga menziesii.

Abstract:
The variability of six Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) populations was studied with the help of needle flavonoids. Of the two proanthocyanidins and six flavonols detected and measured by high performance liquid chromatography, myricetin and prodelphinidin allowed partial separation of the sampled coastal Douglas-fir populations into three geographical groups. Even though conspicuous differences were found between the northernmost and southernmost provenances, flavonoid markers were insufficient to identify the origin of a coastal Douglas-fir population without ambiguity. In accordance with other genetic markers, it would be inappropriate to recognize races within the sampled area of coastal Douglas-fir. From a biogenetical point of view, the synthesis of prodelphinidin appears to be governed by a gene present in two codominant allelic forms. The alleles are differently expressed from one population to another in such a way that there is a latitudinal cline of prodelphinidin throughout the sampled coastal Douglas-fir populations. The gradual decrease of prodelphinidin from south to north tends to support the idea that coastal Douglas-fir has migrated in this same direction from ice-free refugia of the Wisconsin glaciation period. To confirm the latitudinal cline and the mode of inheritance of prodelphinidin in coastal Douglas-fir, additional populations should be analyzed and segregation data from known pedigrees should be obtained respectively.Key words: Pseudotsuga menziesii var. menziesii, Pinaceae, flavonoids, geographical variation.

Abstract:
This study initiated a two-aged forest stand structure by underplanting 50-year-old stands, primarily of Douglas-fir ( Pseudotsuga menziesii (Mirb.) Franco var. menziesii) and Douglas-fir – western hemlock ( Tsuga heterophylla (Raf.) Sarg.), thinned to 19–33 m2/ha on interior and coastal sites in the Oregon Coast Range. Douglas-fir, grand fir ( Abies grandis (Dougl. ex D. Don) Lindl.) (interior site only), western hemlock, and western redcedar ( Thuja plicata Donn ex D. Don) were planted following thinning either uniformly or in gaps of 0.06 or 0.1 ha. Understory vegetation treatments included (i) a preharvest site preparation herbicide application and an untreated control at both sites and (ii) a postharvest herbicide release treatment at the interior site. Planting conditions and stock at the interior site were not ideal, so survival was adjusted for first-year mortality. Adjusted 10 year survival ranged from 27% to 56% for Douglas-fir, 47% to 65% for western hemlock, 61% to 80% for grand fir, and 78% to 96% for western redcedar. Tenth-year survival at the coastal site ranged from 79% to 92% for Douglas-fir, 61% to 75% for western hemlock, and 67% to 86% for western redcedar. All species grew moderately well beneath the lowest-density overstories, and size was better within gaps than matrices for most species. Understory site preparation improved size for most species. Browsing on Douglas-fir and western redcedar impacted size on both sites.

Abstract:
Individual tree mortality models for western white pine (Pinus monticola Dougl. ex D. Don), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), grand fir (Abies grandis (Dougl. ex D. Don) Lindl.), western redcedar (Thuja plicata Donn ex. D. Don), western hemlock (Tsuga heterophylla (Raf.) Sarg.), and western larch (Larix occidentalis Nutt.) were developed using data from permanent research plots located throughout the inland Northwest. The proposed linear logistic models included the following independent variables: diameter at breast height, basal area in larger trees, basal area per hectare, individual tree diameter increment, and a set of dummy variables for the six bedrock types, which were granite, basalt, metasedimentary, sedimentary, mixed – glacial till, and deep deposit. The results show that rock type significantly affects individual tree mortality for western white pine, Douglas-fir, and western redcedar, while grand fir, western hemlock, and western larch were not affected. Western white pine and Douglas-fir growing on meta sedimentary rocks exhibited greater mortality probabilities than on other rocks. Mortality probabilities for western hemlock were low across all rock types, including "nutrient-poor" rocks like metasedimentary types.

Abstract:
The effects of partial cutting on seedling growth of three conifer species were studied at a very dry, hot interior Douglas-fir site near Kamloops, British Columbia. Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco), lodgepole pine (Pinus contorta Dougl. ex Loud. var. latifolia Engelm.), and ponderosa pine (Pinus ponderosa Dougl. ex. P. & C. Laws.) seedlings were planted in mechanically prepared 50 cm × 50 cm patches under different canopy conditions created by harvesting 60% of the original stand volume. The prepared areas were selected to represent canopy closures from open to closed, slopes from 0 to 60%, and all aspects. After six years, survival of Douglas-fir, lodgepole pine and ponderosa pine was 78%, 76% and 70%, respectively. Light level had a strong influence on survival and condition. Growth of all species increased linearly with light, and was greatest for lodgepole pine, followed by ponderosa pine and Douglas-fir. Multiple regression analysis showed that six-year seedling size was most significantly affected by total light, and only occasionally by aspect, slope, or crown closure. The best models explained 53%, 47% and 42% of the variation in diameter of lodgepole pine, ponderosa pine, and Douglas-fir, respectively. Natural abundance 13C was positively correlated with light and soil moisture availability, reflecting higher photosynthetic capacity of all species in the wetter, open canopy conditions. Patterns in isotopic discrimination also indicated greater water use efficiency of Douglas-fir and ponderosa pine than lodgepole pine under low light conditions. Underplanting stands thinned to a basal area of less than 15m2 per ha offers a solution to regeneration difficulties on hot, dry Interior Douglas-fir sites.

Abstract:
Seven wood traits: shrinkage (longitudinal, tangential, and radial), relative density, grain angle, tracheid length, and fibril angle, and two growth traits, height and diameter at breast height were analyzed in 413 trees belonging to 48 full-sibfamilies (4 pollen and 12 seed parents) from an 18- year-old coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) progeny test . Clones from six of the parents also were sampled. Six samples per age level (age levels 0 to 4 along stem radii), with two rings in each age level, were examined in a bolt taken at breast height of the tree for shrinkage and relative density. Smaller sample sizes were used for the other traits. Trends with age from the pith were decreasing longitudinal shrinkage and fibril angle and increasing radial and tangential shrinkage, grain angle, and tracheid length. Relative density first decreased and then increased beyond age level 2. Genetic effects were minimal for wood quality traits except for relative density. Most of the variation for wood quality traits was within tree and between individual trees within families. Genetic correlations between wood quality traits were minimal except between relative density and radial shrinkage, which was positive. Genetic correlations between growth characters like height and diameter at breast height and wood quality traits were also minimal except for relative density and longitudinal shrinkage at early age levels. Selection for increased height can be expected to reduce longitudinal shrinkage and relative density at early age levels, and have virtually no effect on the other traits studied. The results support current efforts to increase wood production through genetic improvement in growth rate by showing that current programs of selection for rapid early height growth will not (with the exception of relative density) result in substantial reductions in several wood quality traits beyond the first few years of tree growth. The demonstrated lack of substantial genetic effects for several traits indicated that genetic improvement can progress more rapidly by concentrating on a much smaller number of traits.

Abstract:
I hypothesized that Douglas-fir trees (Pseudotsuga menziesii) standing apart from other trees ('open-grown') will intercept more rainfall than Douglas-fir trees standing near other trees ('closed-canopy'). Open-grown trees differ structurally and are more common in urban settings, yet have been infrequently studied. Existing literature, based primarily on closed-canopy trees, suggests Douglas-fir trees in Pacific Northwest forests intercept approximately 25% of rainfall annually. Because open-grown trees have more vertical leaf area than individual trees in closed-canopy forests, I expected to find higher interception by open-grown trees. I collected throughfall under four open-grown Douglas-firs using six static collectors ('buckets') per tree, and two closed-canopy Douglas-firs using six buckets per tree. I compared their throughfall to the incident rainfall in two adjacent open-field buckets. Gross interception was measured in 53 collections during rainy weather from 16Nov07 to 31Mar08. Over the same period, rainfall per hour, wind speed, gust speed, wind direction, temperature and relative humidity were collected at a weather station located within 1 km of the site. For comparison, average hourly rainfall at Portland International Airport from 1950 to 2005, for the same months of the collection period, showed a comparable number of medium- to high-intensity storms, but more low-intensity storms. I found that incident rainfall for the adjacent open-field buckets totaled 65.6cm and 71.6cm over the study period. Interception values for closed-canopy trees averaged 26%, corresponding to the literature, with results of 22 and 30%. Interception values for open-grown trees averaged 31%, with results ranging from 15 to 45%. Three of the 24 buckets returned overall negative interception rates over five months. Given the lower storm intensity of 2007-08, interception rates may be somewhat high, compared to the historical average. The negative interception rates at three buckets were likely due to their locations under high drip points, as has been observed in other studies. Considering the wide range of canopy architecture among open-grown trees, the high variability in interception was not surprising. My hypothesis was supported by the data, but requires more testing to better generalize these results. Future studies that link open grown tree canopy morphological characteristics to interception are warranted.

Abstract:
La formation du duramen est un processus physiologique clé impliqué dans la qualité du bois puisqu'il contribue notamment à sa durabilité naturelle. L'objectif de cette thèse est de comprendre les mécanismes mis en jeu lors de la formation du duramen chez le douglas. L'étude a été menée aux niveaux phénotypiques, biochimiques et moléculaires sur plusieurs génotypes de douglas. Des études phénotypiques, il ressort que la proportion de duramen serait sous influence génétique et très peu environnementale, et que l'expansion du bois de coeur se déroule principalement en automne-hiver. Afin de caractériser la composition biochimique du bois, une nouvelle méthode a été développée. Elle repose sur la dissolution du bois dans des liquides ioniques, les solutions obtenues sont ensuite immuno-marquées à l'aide d'anticorps dirigés contre des épitopes de polymères pariétaux. Cette méthode a permis d'observer l'évolution, cerne par cerne, de la composition pariétale du bois de l'aubier externe au coeur du duramen. Certains polymères sont plus abondants dans l'aubier (arabinanes), tandis que d'autres dans le duramen (pectines, xylanes et galactanes). En parallèle, les gènes impliqués dans la formation du duramen ont été étudiés par RNA-Seq à partir de douglas appartenant à un seul génotype et abattus en hiver. Les résultats montrent que des gènes codant des facteurs de transcription, des protéines de défense, des enzymes de la voie de biosynthèse des phénylpropanoides et des enzymes impliquées dans le remodelage de la paroi sont surexprimés dans la zone de transition par rapport à l'aubier. Des hormones, l'éthylène et le jasmonate notamment, semblent jouer un rôle important dans la maturation de l'aubier
The heartwood formation is a key physiological process involved in wood quality because it contributes to its natural durability. The goal of this thesis is to understand mechanisms involved in the heartwood formation in douglas fir. This study has been carried out at phenotypic, biochemical and molecular levels from several douglas-fir genotypes. Thanks to phenotypic analysis, we showed that heartwood proportion is probably under genetic control, and little influenced by the environment. In douglas fir, heartwood expansion mainly occurs during autumn and winter. To characterize the biochemical composition of wood, a new method has been developed. The method implies the wood dissolution in ionic liquid, the solution obtained are then analyzed by immunodetection with monoclonal antibodies against plant cell wall glycan epitopes. Thanks to this method, the wood cell wall composition has been studied, ring-by-ring, from the outer sapwood to the inner heartwood. Some polymers are more abundant in the sapwood (arabinans) while others in the heartwood (pectins, xylans and galactans). Then, genes involved in the heartwood formation have been studied by RNA-Seq from trees belonging to one genotype sampled during winter. Results show that genes encoding transcription factors, defence related proteins, enzymes involved in phenylpropanoid biosynthesis and plant cell wall modification are upregulated in transition zone compared to sapwood. Hormones, ethylene and jasmonate especially, seem to play an important role during sapwood maturation

Abstract:
Insight into influences on successful seedling establishment could be essential to future regeneration of British Columbia’s interior Douglas-fir (Pseudotsuga menziesii var. glauca) forests, particularly as climate changes. Areas of harsh climatic conditions have low regenerative capacity and require management decisions leading to enhanced seedling establishment. Variable retention harvesting and natural regeneration from residual trees, for example, may become increasingly important for their locally adaptive traits as climate changes. Kin recognition, mycorrhizal networks, or the combination of the two may be important mechanisms for enhanced seedling establishment in these regions. We examined the effects of relationship (kin vs. non-kin) and mycorrhizal networks on regeneration from seed in greenhouse and field settings. In the greenhouse, kin recognition was evident in differing foliar microelement (Fe, Mo, Al and Cu) and growth variables (total leaf area, volume and stem length) according to relationships between seedlings. Kin recognition was also weakly evident in the field, where it was expressed as differential survivorship among kin versus non-kin seedlings. Kin selection was evident in the greenhouse, where microelement content of kin was greater than non-kin. Greater mycorrhizal colonization of kin compared to non-kin as well as greater donor total leaf area, volume and stem length also suggest kin selection, although not consistently in all experiments. In the field, survivorship was greater among non-kin; however, detection of kin recognition may have been masked by the large effects of site and seed origin on germination and survival. Mycorrhizal networks and carbon transfer occurred within all greenhouse seedling pairs, and enhanced mycorrhization of kin suggests network colonization was involved in kin selection, but our data does not strongly support our hypothesis that kin recognition was facilitated by mycorrhizal networks. While the mechanism of kin recognition is still not well understood, we provided evidence of kin recognition in interior Douglas-fir seedlings, particularly those that originate from harsh climates, and observed subtle indicators of kin selection or reduction of competition due to a close genetic relationship. Accounting for these phenomena in forest management could be helpful to successful regeneration of interior Douglas-fir forests as stresses associated with climate change increase.

L'étude de la GS aux stades précoces de développement du Douglas a montré I'extstence d'une seule isoforme de masse moléculaire identique à celle de la GS racinaire, et qui n'est que faiblement affectée par la source d'azote disponible. Cependant à des stades de croissance plus avancés, l'absence d'azote et la source d'azote présente affecte non seulement la croissance du végétal mais aussi la répartition de l'activité GS au sein de la plante. Lors de la mycorhization du Douglas par Lac. Bicolor S238N, les GS fongiques et racinaires restent fonctionnelles en proportion égale.

Abstract:
The Sonoran Desert Network (SODN) conducted a vegetation mapping and characterization effort at the two districts of Saguaro National Park from 2010 to 2018. This project was completed under the National Park Service (NPS) Vegetation Mapping Inventory, which aims to complete baseline mapping and classification inventories at more than 270 NPS units. The vegetation map data were collected to provide park managers with a digital map product that meets national standards of spatial and thematic accuracy, while also placing the vegetation into a regional and national context. A total of 97 distinct vegetation communities were described: 83 exclusively at the Rincon Mountain District, 9 exclusively at the Tucson Mountain District, and 5 occurring in both districts. These communities ranged from low-elevation creosote (Larrea tridentata) shrub-lands spanning broad alluvial fans to mountaintop Douglas fir (Pseudotsuga menziesii) forests on the slopes of Rincon Peak. All 97 communities were described at the association level, each with detailed narratives including lists of species found in each association, their abundance, landscape features, and overall community structural characteristics. Only 15 of the 97 vegetation types were existing “accepted” types within the National Vegetation Classification (NVC). The others are newly described and specific to Saguaro National Park (and will be proposed for formal status within the NVC). This document is Volume II of three volumes comprising the Saguaro National Park Vegetation Mapping Inventory. This volume provides two-page summaries of the 97 associations identified and mapped during the project, and detailed in Volume I. Summaries are presented by district, starting with the Tucson Mountain District. These summaries are abridged versions of the full association descriptions found in Volume III.

This document is Volume III of three volumes comprising the Saguaro National Park Vegetation Mapping Inventory. This volume provides full type descriptions of the 97 associations identified and mapped during the project, and detailed in Volume I. Volume II provides abridged versions of these full descriptions, briefly describing the floristic and structural characteristics of the vegetation and showing representative photos of associations, their distribution, and an example of the satellite imagery for one polygon.
