Displaying 581 - 585 of 2258Roads in the Southwestern Amazon, State of Acre, between 2007 and 2019
Over the past 40 years, roads have been the main driver behind the State of Acre’s occupation and development. However, the expansion of roads, has often been associated with the advance of deforestation, habitat fragmentation, and social conflicts. There are no up-to-date data available on the current extent of Acre’s road network nor its environmental and socioenvironmental impacts. In this study, we updated the State of Acre’s road network map for the period 2007 to 2019 through the visual interpretation of 153 Landsat images (5, 7, and 8) at a scale of 1:50,000.
Which Traits Influence Bird Survival in the City? A Review
Urbanization poses a major threat to biodiversity worldwide. We focused on birds as a well-studied taxon of interest, in order to review literature on traits that influence responses to urbanization. We review 226 papers that were published between 1979 and 2020, and aggregate information on five major groups of traits that have been widely studied: ecological traits, life history, physiology, behavior and genetic traits. Some robust findings on trait changes in individual species as well as bird communities emerge.
Landscape Perception and Public Participation for the Conservation and Valorization of Cultural Landscapes: The Case of the Cinque Terre and Porto Venere UNESCO Site
Europe retains a great variety of cultural landscapes that constitute a significant part of the European cultural heritage. In the last decades, these high-quality landscapes are facing several challenges due to socio-economic transformations that often compromise their integrity. This situation is even worse for terraced landscapes, as in the case of the Porto Venere and Cinque Terre UNESCO World Heritage List site.
Landscape and Tourism as Tools for Local Development in Mid-Mountain Rural Areas in the Southeast of Spain (Castilla-La Mancha)
The modernization of economic activities in mountain areas is conditioned by the physical characteristics of the territory, the weight of activities related to the primary sector, infrastructure deficits, low population density, as well as the declining and ageing population. The response to this situation has involved implementing a certain degree of functional diversification. One of the aspects that has assisted in the expansion of the tertiary sector is leisure and recreational activities.
Forest Disturbance Types and Current Analogs for Historical Disturbance-Independent Forests
Forest classifications by disturbance permit designation of multiple types of both old growth forests and shorter-lived forests, which auto-replace under severe disturbance, and also identification of loss of the disturbance type and associated forest. Historically, fire and flooding disturbance regimes, or conversely, infrequent disturbance, produced unique forests such as disturbance-independent forests of American beech (Fagus grandifolia), eastern hemlock (Tsuga canadensis), and sugar maple (Acer saccharum) in the Eastern United States.
