Seminatural European grasslands and pastures have a high conservation value because they provide different goods and services (meat, wool, carbon sequestration, etc.) and harbor diverse communities of plants and animals. These land use systems were created by low-and moderate-intensity use and, nowadays , face threats from both abandonment and over...
Game species with home ranges exceeding the area of the management units may entail conflicts over hunting rights and cause damage to crops and forest stands in surrounding areas. This is currently the case in the Mendro Mountain Range (Portugal), inhabited by free-ranging red (Cervus elaphus) and fallow deer (Dama dama) populations. This study’s p...
ArcGIS toolbox for landscape dynamics assessment.
QGIS tool for landscape dynamics assessment.
Abstract: Invasive alien species are responsible for several negative impacts worldwide. Managing biological invasions is often difficult and the success rate is quite low but with good planning it is possible to achieve good results. Besides employing the correct methods and techniques, an overall strategy based on landscape dynamics and expected...
Recent findings on the contribution of smallholders to global food production and security challenge the values used in several reports of international organizations. The skewed distribution of the number of farms and the agricultural area by farm size may explain overestimations in small farms' food production. In fact, the highest values found i...
As paisagens podem ser caracterizadas como um mosaico resultante de uma fusão de elementos naturais e antrópicos que variam em tamanho, forma e estrutura (FORMAN; 1981), e que provêm da integração espacial e temporal de múltiplas funções ambientais, sociais e económicas (2001). Esta integração é materializada nas estruturas sociais e nos sistemas d...
The “LDTtool” python toolbox is introduced. This ArcGIS toolbox can be applied to assess land cover or land use changes between two or three moments, considering landscape composition and configuration. The development of LDTtool occurs in a time when the studies on landscape dynamics looking at amount and configuration changes are becoming mainstr...
ContextThe Portuguese montado is an agro-silvopastoral system, similar to the Spanish dehesa, known for its cultural, economic and ecological value. Despite its importance, contrasting processes such as land abandonment and land use intensification, together with several other factors, have been responsible for montado degradation in the last decad...
Wild rabbit is a relevant species in the Iberian Peninsula due to its ecological and economic roles. Conservationists and game managers therefore have a shared interest in assuring the existence of resilient and sustainable populations. Although management principles and guidelines are mostly known and understood, often the results are not as good...
LDTtool is an ArcGIS toolbox that implements the Landscape Dynamics Typology method (Machado et al., 2018) to assess landscapes.
Wild rabbit is a very important species in the Mediterranean region. Its relevance is both ecological, being a keystone species —prey for several predators— and economic, as it is the most important and the most managed small game species among mammals in the Iberian Peninsula. Although both researchers and game managers claim restocking operations...
Landscape transformations have been a central topic in landscape ecology due to their influence on ecosystem services and biodiversity conservation. Landscape dynamics can be very complex and one of the most difficult issues to analyse is the contribution and the effects of landscape composition and configuration changes to the overall impact. We e...
Although the extractive operations of quarrying are often considered environmental threats, there is some evidence that abandoned quarries may have a significant positive impact on biodiversity by enhancing habitat quality for several species. In Estremoz Anticlinal, SE Portugal, many of the existing marble quarries have been inactive for decades a...
Fire is infrequent in the oak woodlands of southern Portugal (montado) but large and severe fires affected these agro-forestry systems in 2003-2005. We hypothesised transition from forest to shrubland as a fire-driven process and investigated the links between fire incidence and montado change to other land cover types, particularly those related w...
Montado decline has been reported since the end of the nineteenth century in southern Portugal and increased markedly during the 1980s. Consensual reports in the literature suggest that this decline is due to a number of factors, such as environmental constraints, forest diseases, inappropriate management, and socioeconomic issues. An assessment on...
www.sciencedirect.com search for "Landscape" AND "Ecology" after 2000
The aim was to find where Landscape Ecology is being studied and used in forest management, land cover dynamics, invasive species modeling, ecosystem disturbance, ecological restoring, species conservation, etc.
Understanding the relationship between spatial patterns of landscape attributes and population presence and abundance is essential for understanding population processes as well as supporting management and conservation strategies. This study evaluates the influence of three factors: environment, habitat management, and season on the presence and a...
O Livro Verde dos Montados apresenta diversos objectivos que se interligam: Em primeiro lugar, o Livro Verde pretende reunir e sistematizar, de uma forma simples e acessível ao público, o conhecimento produzido em Portugal pelos investigadores e técnicos de várias instituições de investigação ou de gestão que estudam o Montado. Assume-se como uma o...
