Abstract:

Abstract:Although predation is generally seen as one of the key factors determining the abundance and composition of insect herbivore communities in tropical rain forests, quantitative estimates of predation pressure in rain-forest habitats remain rare. We compared incidence of attacks of different natural enemies on semi-concealed and exposed caterpillars (Lepidoptera) in lowland and montane tropical rain forests, using plasticine models of caterpillars. We recorded attacks on caterpillars in four habitats: primary forest, secondary forest and forest fragment in lowlands (200 m asl), and mont

Abstract:

Globally, forests are constantly threatened by a plethora of disturbances of natural and anthropogenic origin, such as climate change, forest fires, urbanization, and pollution. Besides the most common stressors, during the last few years, Portuguese forests have been impacted by severe decline phenomena caused by invasive pathogens, many of which belong to the genus Phytophthora. The genus Phytophthora includes a large number of species that are invading forest ecosystems worldwide, chiefly as a consequence of global trade and human activities.

Abstract:

The dry forests of southern Ecuador are characterized by a great floristic variety and high endemism rates in different taxonomic groups; however, these forests are disappearing at an alarming rate due to anthropogenic disturbances. Epiphytic cryptogams (bryophytes and lichens) are important in seasonally dry tropical forests (SDTFs) and, due to their physiology (poikilohydric species), are sensitive to the changes associated with specific human disturbances. We examined the response of epiphytic cryptogams to habitat disturbance in SDTFs (natural and semi-natural forests) by registering the f

Urgent and widespread revegetation of agricultural landscapes is required to slow and remediate these impacts. Simultaneously, the extent of abandoned agricultural land, often referred to as old-fields, is increasing worldwide due to a range of socioeconomic factors, providing sig

Rather than being wholly exploitative, commercial influences during the 18th and 19th centuries may, in fact, have helped temper further woodland decline. It is now generally recognised that non-commercial influences may have been more significant in the evolution of woodlands in the historic period. It is now gene

Abstract:

A decline in biodiversity in agricultural landscapes has been reported for decades. One of the most important habitats for biodiversity in agricultural landscapes is semi-natural grasslands. To preserve species-rich semi-natural grasslands, research need to focus both on local habitat quality and on landscape composition at various scales. In the current study I examined how nectar sources, host plants and other environmental parameters affected the occurrence of adults of four burnet moth species, residents of semi-natural grasslands.

Those impacts range from industrial development to farming and urbanisation.

По данным метеонаблюдений, в Башкирии за последние 30 лет среднегодовая температура воздуха повысилась на 0,7 0С. Это соответствует общемировым тенденциям. За сто последних лет среднегодовая температура воздуха в России повысилась на 1,29 С, а в мировом масштабе на 0,74. Изучение изменений флористического состава городских парков и лесопарков за продолжительный период позволяет оценить влияние антропогенного трансформирования территории и изменения климати

Abstract:

The introduction of exotic species has led to the simplification of native biota, as well as causing various other negative effects on natural and man-made ecosystems. The process responsible for causing this problem is called biological invasion (BI). Among the species responsible for promoting BI is the grass Megathyrsus maximus (Jacq.) B.K.Simon & S.W.L.Jacobs. The aim of this study was to assess the impacts caused by the invasive exotic species on the composition, richness and diversity of the native vegetation of the Atlantic Rainforest. The work was carried out in the Serra de Itabai

Abstract:

Landscape changes are an inevitable process. However, the dynamics and magnitude of these changes have increased worldwide since the 19 th century, accelerating after the Second World War. As a result, many traditional landscapes have deteriorated rapidly. While in intensively used areas traditional landscapes have been completely wiped out, in extensively used areas they gradually evolve into afforested, restored, or semi-natural ones. This stems from progressive land abandonment that in temperate zone results in reforestation, and usually in the loss of some natural and cultural values. This

Abstract:

A major concern in the forest industry is impact on the soil caused by forest machines during harvesting. A six-wheel pendulum arm forwarder is being developed. The new forwarder aims at reducing soil damage by an even pressure distribution and smooth torque control and thereby also improving the working environment. The suspension contains pendulum arms on each wheel controlled by a hydraulic load sensing system in combination with accumulator. A natural approach is to model each part of a system in the best-suited software. In this case, the hydraulic system is modelled in the Hopsan simulat

Abstract:

This paper introduces the design data and numerical analysis of a braceless steel semi-submersible wind turbine. The hull of the semi-submersible wind turbine is designed to support a reference 5-MW horizontal axis wind turbine at a site in the northern North Sea. The hull is composed of a central column, three side columns and three pontoons. The side columns and pontoons are arranged radially outward from the central column which is used to support the wind turbine. The side columns form the corners of a triangle on the horizontal plane and are connected by the pontoons to the central column

Abstract:

This study investigates the economic and environmental implications of converting Cambodia’s natural forests into alternative land uses. Using a Total Economic Value (TEV) framework and a value flow model, the research assesses direct and indirect benefits of evergreen, semi-evergreen, and deciduous forests, including non-timber forest products (NTFPs), sustainable timber harvesting, carbon sequestration, and watershed protection. Household surveys across four provinces reveal that forest resources contribute significantly to rural livelihoods, especially among poorer households. The study eva

This mapping effort was accomplished through collaboration with the Southeast regional office of NatureServe (Raleigh/Durham, N.C.). The mapping area was 15,163.4 hectares (ha), encompassing the entire boundary of the seashore plus an additional buffered area. NatureServe ecologists identified plant associations for the seashore and a remote sensing specialist from the Southeast Coast Network

Abstract:

The Southeast Coast Network conducts long-term terrestrial vegetation monitoring as part of the nationwide Inventory and Monitoring Program of the National Park Service. Vegetation in parks is monitored as a key vital sign and indicator of overall ecosystem health because changes in vegetation condition reflect effects of stressors such as extreme weather, disease, invasive species, fire, and land use change. Plants also provide the structured habitat and food resources on which other species depend. Monitoring plants and their associated communities over time allows for targeted understanding

The use of bee natural product for enhancing pollination is especially valuable in problematic crops that are generally avoided by bees. In the present research we attempted to enhance bee visitation to Male Sterile (M-S) tomato flowers generally used in the production of hybrid seeds. These flowers that lack both pollen and nectar are unattractive to bees that learn rapidly to avoid them. The specific objects were to elucidate the chemical composition of the exocrine products of two bumble bee species the North American Bombus impatiens and the Israeli B. terrestris.
