Season and drought stress mediate growth and weight of the green spruce aphid…

1 The most important defoliating pest of Sitka spruce Picea sitchensis in the U.K. is the green spruce aphid Elatobium abietinum. This aphid species is expected to respond to a predicted increase in the incidence of spring–summer drought events, with serious implications for growth of infested spruce plants and control of the pest. 2 Growth rate, adult weight and nymph weight of E. abietin…

First report of Curvularia eragrostidis leaf spot on Populus deltoides

Poplars are affected by a large number of foliar pathogens in nurseries and in the field, which result in biomass reductions. Management of these diseases is essential to minimise losses. During field surveys between 2008 and 12, an unrecognized leaf spot disease was observed on several commercial clones of P. deltoides (G-48, Udai, WSL-22 & WSL-39). The pathogen was identified as Curvularia er…

Molecular evidence for bamboo as a new natural host of Cherry necrotic rusty …

Himalayan ‘maggar’ bamboo (Dendrocalamus hamiltonii), widely distributed in the Himalayas, was found to exhibit mild virus-like symptoms, which included mosaic, chlorosis, necrotic spots and mottling. Leaf samples from symptomatic plants were subjected to reverse transcription polymerase chain reaction (RT-PCR) for the detection of Cherry necrotic rusty mottle virus (CNRMV). Sequencing of t…

Habitat Loss Reduces the Diversity of Frog Reproductive Modes in an Atlantic …

Several amphibian species have ecological traits that can make them vulnerable to landscape changes, such as habitat preference and reproductive strategies. We evaluated how anuran species and their respective reproductive modes were distributed in an Atlantic Forest fragmented landscape, Southeastern Brazil. We sampled through visual encounter surveys three continuous forest sites, 12 forest f…

This is the first report of Monochamus sutor as vector of B. mucronatus kolymensis, the European type of B. mucronatus (synonymous with B. kolymensis) in Spain. In 2013, a female of Monochamus sutor was caught in a Pinus sylvestris forest. Nematode species identification was based on morphological characteristics and on molecular and phylogenetic analysis of dauer juveniles and adults.

Biodiversity, Biofuels, Agroforestry and Conservation Agriculture

Today’s agriculture has to face the new challenge that derives from a new evolutionary era of civilisation that has been called “Anthropocene”. Human dominion on Earth with exploitation of natural resources and environmental pollution is not socially acceptable anymore, since it leads to self-destruction in a confined “spaceship” like the planet Earth. A different cultural attitud…

Potential of Agroforestry and Plantation Systems in Indonesia for Carbon Stoc…

This paper investigates the carbon sequestration potential of several alternative agroforestry and plantation systems in Indonesia. It is shown how different agroforestry systems vary in their attractiveness in terms of carbon sequestration, returns to land and labour and employment potential. A twenty-year life cycle of coffee multi-cropping systems is compared to short-rotation timber pla…

Forest Trees

Forest trees are integral parts of human society. They provide fuel, fiber, construction and building materials, food, and medicines, among other things. The forest itself is an ecosystem, and as ecosystems, forests stabilize environments and are essential components of the global ecology. Although trees are the dominant vegetation, forests are rich reservoirs of biological diversity. They har…

Forest Management For Wildlife

Summary. Wildlife is an integral part of the wooded areas of Kansas and a resource that is favored with little or no loss to timber production. Forests offer wildlife protection from wind and snow, refuge from predators, and a variety of foods not found in other landscapes. Properly managed forests provide habitat for wildlife such as squirrels, deer, turkey, and songbirds. Other wildlife spe…

Urban Forestry: Toward an Ecosystem Services Research Agenda: A Workshop Summary

Many participants noted that the workshop provided a valuable opportunity to reflect on the state of science regarding the role of trees in urban ecosystems, and that it identified knowledge gaps and challenges in translating science into practice. These discussions drew on the expertise of scientists from multiple disciplinary perspectives and of stakeholders from a wide variety of public …

Hydrologic Effects of a Changing Forest Landscape

In 1976, a group of Forest Service scientists1 published a seminal volume on forests and water that evaluated the effects of forest management on floods, sedimentation, and water supply. It was one of the first comprehensive attempts to link upstream forest management with downstream water management and supply. For many years, this report served as a critical reference for forest hydrolog…

Forested Landscapes in Perspective: Prospects and Opportunities for Sustainab…

Forests are an important part of everyday life for most Americans. They provide timber, soil, wildlife, recreation, beauty, and relief within rural and urban environments. An issue of increasing concern is the management of forestlands for diverse objectives, including economic returns, biological and ecological integrity of forest resources, and quality of life for populations in rural and…

Environmental Issues in Pacific Northwest Forest Management

In response to a congressional request, the Board on Biology convened the Committee on Environmental Issues in Pacific Northwest Forest Management in 1993 to review information concerning the status of resources of the Pacific Northwest and the relationship of those to supply and demand for forest products in other regions of the country. Committee members were selected for their expertise…

Biologic Markers of Air-Pollution Stress and Damage in Forests

There is not much question about the sensitivity of plants to air pollution, nor is there doubt that air pollution is affecting forests and agriculture in Europe, North America, Brazil, and elsewhere. The effects on forests are well known—they follow patterns of impoverishment long recognized as the result of chronic disturbance. Depending on the severity of the disturbance, the results are…

Demographic consequences of chromatic leaf defence in tropical tree communiti…

Background: Many tropical forest tree species delay greening their leaves until full expansion. This strategy is thought to provide newly flushing leaves with protection against damage by herbivores by keeping young leaves devoid of nutritive value. Because young leaves suffer the greatest predation from invertebrate herbivores, delayed greening could prevent costly tissue loss. Many species …

Canopy structure of tropical and sub-tropical rain forests in relation to con…

Background and Aims: Globally, conifer dominance is restricted to nutient-poor habitats in colder, drier or waterlogged environments, probably due to competition with angiosperms. Analysis of canopy structure is important for understanding the mechanism of plant coexistence in relation to competition for light. Most conifers are shade intolerant, and often have narrow, deep, conical crowns. I…

PINE WILT A fatal disease of exotic pines in the Midwest

Summary. PINES HAVE EARNED A SECURE NICHE IN America’s urban landscape thanks to their diversity, adaptability, and beauty. Over the past 20 years, however, a disease called pine wilt has killed so many Scots pine (Pinus sylvestris) in the Midwest that extension specialists in several states no longer recommend planting this oncepopular species as a landscape tree. This bulletin explains how…
