Book excerpt: This study assessed the effects of thinning on arthropod communities on understory plants in the Central Oregon Coast Range. Arthropods were sampled from five understory plants in five pairs of thinned and unthinned, young (50-80 yrs), managed Douglas-fir stands, from late May to mid-July of 1998. Vine maple (Acer circinatum), salal (Gaultheria shallon), understory hemlock (Tsuga heterophylla), bracken fern (Pteridium aquilinum), and sword fern (Polystichum munitum) were sampled for arthropods using beating sheet and aspirators. Arthropod taxa were sorted and identified to family, species where possible. Intensities and diversity indices were calculated both for all arthropods (including spider taxa) and for spiders separately. Arthropods were placed into functional groups based on trophic level/feeding habits. Spiders were placed in guilds based on prey capture strategies. Collembolans, psocopterans, aphids and linyphiid spiders together made up 50% of total arthropod abundance. Spiders made up 23% of the total arthropod abundance. Functional groups overall were not found in different intensities between thinned and unthinned stands. Relative representation of spider guilds was different between thinned and unthinned stands. Cobweb weavers and nocturnal hunters had higher intensities in thinned stands. Sheetweb weavers, orbweb weavers and agile hunters had higher intensities in unthinned stands. Sap-suckers on vine maple were more abundant in unthinned stands. Parasitoids on vine maple were more abundant in thinned stands. Agile hunters on salal were more abundant in unthinned stands. Salal, especially in unthinned stands, provided important structure for spider communities. Salal supported high spider diversity. Hemlock had the highest species richness, for both arthropod and spider communities. Communities on vine maple were diverse, despite low overall arthropod abundance. The arthropod communities showed significant segregation by plant species and treatment condition. Shrub cover, shrub diversity, patch size, light levels, tree density and stand age explained arthropod community differences. Each one of the understory plants I studied supported a unique portion of the overall understory arthropod community and should be maintained in managed forests to support this important element of diversity. Differences in species distribution and structure of understory vegetation between treatments, resulting in arthropod community differences, suggests that maintenance of both treatment conditions across a landscape is important for maintaining diversity of understory arthropod communities.

This book was released on 1998 with total page 236 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "old-growth controversy" in the Pacific Northwest recognized thinning as the primary silvicultural practice for land managers to produce wildlife habitat while continuing to produce timber. For the foreseeable future, forest stands will be harvested to produce forest gaps and a patchwork of trees of different ages. In order to evaluate the effect of thinning on biodiversity, nine 15-year-old harvests of this type (age=70 years) were paired with adjacent old-growth and even-aged, unthinned "pole" stands. Since soil is the crucible of terrestrial biodiversity, it is critical to contrast the effects upon the forest floor of this future practice with current management. Soil and litter fauna were monitored along 250 meter transects (pitfall and Berlese sampling at ten-meter intervals) to meet the following objectives: 1) to determine biological diversity on public lands, per federal mandate, and use diversity as a management tool; 2) compare levels of biodiversity between three management strategies; 3) determine best methods to assay arthropod diversity; and 4) identify structural and environmental determinants of arthropod diversity and abundance. The study's hypotheses were: 1) old-growth forests will have greater arthropod diversity than thinned stands; 2) thinned stands will have greater arthropod diversity than unthinned stands; and 3) species found within old-growth stands, but not within unthinned pole stands, will also be found in thinned stands. This study contrasted nine Western Hemlock/Douglas-fir sites each with contrasting old-growth, thinned and unthinned pole management stands. Sites were equally blocked in Southern Oregon, the Coast Range, and the Cascade Mountains. No segment of the arthropod fauna. (i.e., pitfall-trapped epigeic macroarthropods, Berlese-extracted litter-dwelling meso- and microarthropods, or soil-dwelling microarthropods) exhibited a management (treatment) effect throughout the entire region. When the regional blocking was removed, within-region analysis generally revealed that old-growth was most distinct. Old-growth stands had the highest abundance of individuals, but were comprised of the fewest species. Thinned stands were characterized by the highest species richness. Within-region analysis revealed an interaction of management effects and specific locale effects; locale effects dominated for soil microarthropods and epigeic macroarthropods, while management options dominated for litter arthropods. Within the Southern Oregon region, I attempted to correlate arthropod community structure (canonical correspondence analysis (CCA) of within-stand samples) with a suite of soil chemical and microbiological descriptors. Full analysis of twelve variables within one exemplary stand revealed several potential trends (negative: dissolved organic carbon, soil moisture, distance from the beginning of the transect; positive: total CO2 field respiration, mineralizable nitrogen, water-induced respiration, substrate-induced respiration). Relatively shallow slopes and very low r-value coefficients of correlation characterized all statistical tests. Few of the trends apparent at one site were paralleled at more than one other site; at all sites potential correlates had very low r-values. No community revealed separate clouds in CCA analysis, indicating distinct "micro-communities" of arthropods inhabiting distinct micro-habitats. Lack of distinctive species assemblages and lack of correlation with microhabitat variables indicated that arthropods respond on different temporal and/or spatial scales then the microbial-oriented variables, and that each taxon is responding in an individual manner.

Available in PDF, EPUB and Kindle. Book excerpt: The process of silvicultural thinning has become very controversial recently with regards to fire protection and management for old-growth conditions and biodiversity. Therefore, an unthinned control stand and 3 different thinning intensities were examined for their effects on the abundance, species richness, and diversity of arthropods in thinning treatments of silvicultural practices. Study sites were 40-50 year-old young stands of typical plantation Douglas-fir forests in the Willamette National Forest, Oregon. Shrub-, ground-, and litter-dwelling arthropods were collected with a bagging technique, pitfall traps, and Berlese extraction during 2000 and 2001. Abundance of shrub-dwelling arthropods decreased with the thinning intensity for deciduous foliage, but did not show any response for conifer foliage. Species richness and diversity of shrub-dwelling arthropods showed higher values in the conifer foliage types. Functional group composition for the two foliage types revealed consistently different proportions; the deciduous foliage type had a higher proportion of plant suckers and the conifer foliage type had higher proportion of predators and detritivores. NMS ordination (Non-metric Multidimensional Scaling) showed a very distinct difference between the species inhabiting the two contrasting foliage types. Abundance and diversity of ground-dwelling arthropods were higher in Heavy Thin and Light Thin with Gap treatments than the Control and Light Thinning treatments. Five groups of arthropods with relatively high abundance (such as Formicidae (ants), Araneae (spiders), Carabidae (ground-beetles), Gryllacrididae (camel-crickets), and Polydesmida (millepedes)) permitted in depth analysis. Four groups (i.e., ants, spiders, camel-crickets, and millipedes) were more abundant in the more intense thinning treatment areas. However, the abundance of Carabidae (ground-beetles), the third most abundant group, was higher at the unthinned control than in any thinning treatments; densities were much higher during the wet season than dry season. NMS ordination showed that seasonal effects outweighed the thinning effects. Though the disturbance associated with thinning would be expected to decrease populations and density of fauna, I hypothesize that the principal effect of the thinning disturbance was to increase habitat heterogeneity and subsequently species richness. Abundance of litter-dwelling arthropods decreased in proportion to the thinning treatments. The litter-dwelling fauna was primarily correlated with seasonal moisture and secondarily positively correlated with thinning intensity. The proportion of predators decreased with the advancing seasons.

Metcalf and published by . This book was released on 2013 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasion by non-native primary producers are generally expected to lead to a decline in native species richness, however in some cases, these invasions can actually lead to an increase in diversity and abundance of certain groups of organisms. Arthropods are extremely sensitive to changes in the plant community, particularly herbivores, and the response of these primary consumers can influence predator populations. Microstegium vimineum is an invasive C4 grass that has developed strong populations in the understory of temperate deciduous forests along the east coast of the U.S. This work evaluates the influence that this invader may have on insect and spider abundance and diversity, including changes at the trophic group and functional guild levels. Additionally we evaluate the impacts of both an increase in invasion density and a decrease in native plant diversity on arthropod community structure. In general, we find a significant increase in herbivore abundance, primarily as a result in the increased abundances of concealed chewers, free-living chewers and free-living sap feeders. Free-living sap-feeders also showed an increase in biomass. Spider abundance and diversity also increased in association with invasion by M. vimineum. Both active hunters and sit-and-wait predators showed significant increases in invaded sites. The ratio of adult:immature spiders however had a negative relationship with invasion. These changes in the arthropod community appear to be related to both changes in vegetation structure as well as changes in plant biomass. We found increased abundances in our treatments in which invasion density increased and decreases in the arthropod community in sites where native plants were removed from the system. We also show some support for the idea that carnivores, specifically spiders, may respond more strongly to changes in vegetative complexity, while herbivores, specifically leaf hoppers, may respond more strongly to changes in plant biomass.

This book was released on 2001 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive ecosystem management is a new paradigm for managing federal forests which requires regular monitoring of ecosystem function and diversity to measure the effects of management. Managers need new strategies and tools to help them assess their progress in maintaining healthy, productive and biologically diverse forests. Biomonitoring of select forest macro-arthropod species can provide useful information on the effects of management on forest biodiversity and ecosystem function. The purpose of this study was threefold: (1) to inventory the macro-arthropod community and important environmental variables in the Bear Creek and Indian Creek study area within the Payette National Forest (PNF) in Western Idaho; (2) to compare measures of community composition, diversity, and structure in forest macro-arthropod communities between patches of different sizes and treatment; and (3) to assist PNF managers in their ecosystem management efforts by providing principles to guide the use of macro-arthropods as indicators of changing forest conditions. Transects with pitfall traps were used to collect macro-arthropods at 22 sites in the Bear Creek and Indian Creek study area during the summer of 1994. Five forest patch types in Abies grandis habitat types were sampled. Intact forest patches of 100 or more hectares, and large patches of 50-100 hectares, ranged in age between 50 and 250 years old with multistoried structure. Small patches up to 10 hectares were remnants or fragments of formerly intact forest isolated by logging. A plantation patch was 15 years old with patchy understory and forb cover. Clearcut patches had little or no overstory, and variable understory, and forb layers. At each transect, soil samples were collected and six environmental descriptor variables were analyzed according to patch treatment and patch size. These site descriptors were: basal area (ft2/acre); percent canopy cover for the overstory, understory; and forb layers; litter depth (cm), and percent soil moisture content. Differences detected using an ANOVA and T-tests are discussed in the Results section. Arthropod community composition, diversity, and structure were described according to relative abundance, and four measures of diversity. They were also described by membership in seventeen orders and/or super-families; ten functional groups; two disperser classes (long or short distance); and three species indicator classes. A total of 5455 macro-arthropod individuals, representing 17 orders and/or super-families and 219 species were collected in the Bear Creek and Indian Creek study area. While macro-arthropod fauna relative abundance did not vary significantly by treatment (ANOVA p

This book was released on 2000 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edge effects resulting from forest fragmentation are likely to alter the distributions and interactions of resident species. I evaluated changes in species composition, species turnover, and relative abundance of ground arthropods across replicated transects extending from regenerating clearcuts into old-growth Douglas-fir forests. Arthropods were collected from 3-August to 14-September in 1997 and 23-May 1998 to 31-July 1998 using pitfall traps. Pitfall traps were positioned at 75 m (in the clearcut), -25, 0 (forest edge), 50, 100 and 200 m into the forest in 1997. In 1998, traps were repositioned at 25, 0, 25, 50,lOO, and 200 m into the forest. Changes in species composition and relative abundance were compared using non-metric multidimensional scaling ordination. Two-hundred, five species representing 24,178 individuals were collected. Edge effects on species composition and relative abundance were apparent up to 100 m into old-growth forests. Species were characterized as edge-phobic (interior forest associates), edge-philic, edge-insensitive or as edge-input (clearcut associates). The majority of species were characterized as either edge-phobic or edge-input species. Seasonal patterns in activity are also reported. To further address the impacts of edges on community structure, changes in species abundance of predator taxa across the edge-forest gradient were compared to four models of resource partitioning. Observed patterns of species abundance did not differ across the edge-forest gradients and were consistent with a model of random assortment (or non-equilibrium) where an individual predator species utilizes resources independently of other predators. This pattern was consistent whether species abundance was expressed as numerical abundance or biomass. This study suggests that edge effects resulting from forest fragmentation alter species composition and may negatively affect interior forest species. Furthermore, although species composition changes across forest edges, this study suggests that resource partitioning by a trophic group such as predators remains unaffected by forest edges.

Available in PDF, EPUB and Kindle. Book excerpt: Agrilus auroguttatus (goldspotted oak borer) is an invasive wood-boring beetle that is killing Quercus agrifolia (coast live oak) in San Diego County and spreading to other counties in Southern California. A. auroguttatus has been in San Diego County for over a decade and has had unknown effects on other aspects of the oak woodlands. These unknown indirect effects were studied in this thesis by looking into understory plants and arthropods under varying crown conditions. Oak demographic changes were important to determine if these oak woodlands are able to replace themselves. Understory plant composition was valuable to understand because changes in composition may alter ecosystem production and future trajectories. Understory arthropods represent many trophic levels, are easy to capture, and respond relatively quickly to changes in the environment. Eight oak woodlands with 14 trees per woodland were studied. General linear models were used to look at specific responses due to differences in crown condition and number of neighboring trees, and nonmetric multidimension scaling was used to visualize and evaluate clustering of multiple response variables. We determined that there were distinct plant and arthropod communities under individual oak trees depending on canopy condition. Overall, it appears that oak recruitment may not be in a linear decline after A. auroguttatus enters the system but may be more complicated.

Forests form the natural vegetation over much of the Earth’s land, and they are critical for the survival of innumerable organisms. The ongoing loss of natural forests, which in some regions may have taken many millennia to develop, is one of the main reasons for the decline of biodiversity. Preventing the further destruction of forests and protecting species and ecosystems within forests have become central issues for environmental agencies, forest managers, and gove- ments. In this di?cult task science has an important role in informing policy and management as to how to go about this. So how do industrial and other pl- tation forests ?t into this? Plantation forests, comprised of rows of planted trees that may be destined for pulp or sawmills after only a few years of growth, appear to have little to c- tribute to the conservation of biodiversity. Yet there is more to this than meets the eye (of the casual observer), and there are indeed numerous opportunities, and often untapped potential, for biodiversity conservation in plantation forestry. With plantation forests expanding at a rate of approximately three million hectares per year, it is crucial to understand how plantations can make a positive contribution to biodiversity conservation and how the potentially negative impacts of this land use can be minimised. That is the topic of this book.

Book excerpt: This is the 7th edition of the FAO's biennial report on the state of global forest resources, recent developments and emerging issues in the forest sector. This edition focuses on progress towards sustainable forest management at the regional and global levels, with each regional report structured according to seven thematic elements: the extent of forest resources; biological diversity; forest health and vitality; productive functions of forest resources; protective functions of forest resources; socio-economic functions; and legal, policy and institutional frameworks. These summaries are based on the most current information available, including new data from the Global Forest Resources Assessment 2005 (FRA 2005). The report goes on to consider 18 key issues in the forest sector, including: climate change, forest landscape restoration, forest tenure, invasive species, wildlife management and wood energy. The overall conclusion is that whilst progress is being made, it is very uneven with those regions with developing economies and tropical ecosystems continuing to lose forest area whilst lacking adequate institutions to reverse this trend. The biggest limitation for evaluating progress is weak data, with many countries lacking the financial resources to undertake national forest assessments.

Book excerpt: In this volume, international experts describe biological, ecological, economic and social aspects of planted forests. Representative types of planted forests are described and discussed, technical and social aspects are considered, and case studies depict the variety of purposes and uses of planted forests. Authors discuss the nature of planted forests of representative species world-wide, basic biology and ecology of plantations, and economic and social considerations in landscapes where planted forests contribute to potentially sustainable societies. The authors represent temperate and tropical forests, developed and developing nations, and all levels of intensity of planting and managing forest trees. This compilation of views and viewpoints about planted forests provides a fresh, broad outlook on trees planted for myriad purposes. Forest scientists and managers, policy experts, development officials and interested citizens will find information of value and stimuli for thinking about forestsof the future.
