Different bat guilds perceive their habitat in different ways: a multiscale landscape approach for variable selection in species distribution modelling

Journal Articles & Books
Diciembre, 2015
Italia

CONTEXT: Unveiling the scale at which organisms respond to habitat features is crucial to understand how they are influenced by anthropogenic environmental changes. We implemented species distribution models (SDMs) based on multiple-scale landscape pattern analysis for four bat species representative of different foraging guilds: Nyctalus leisleri, Rhinolophus hipposideros, Myotis emarginatus and Pipistrellus pipistrellus.

Inhibition of an invasive plant (Mikania micrantha H.B.K.) by soils of three different forests in lower subtropical China

Journal Articles & Books
Diciembre, 2011
China

Biological invasion represents one of the most serious threats to biodiversity, and invasion ecology research has become one of the central issues of contemporary environmental science. However, the relative role of soil development as correlated with succession in influencing variation in invasion resistance has seldom been examined. We hypothesized that the invasion potential of exotic plants depends on soil conditions. In this study, we explored variation among soils of three forest types in their resistance to invasion by Mikania micrantha H.B.K.

Web-based system for vineyards management, relating inventory data, vectors and images

Journal Articles & Books
Diciembre, 2010
Brasil

A Web-based system is presented, integrating spatial information from remote sensing images, GPS measurements and inventory data. Monitoring, research and management of the grape production at Rio Grande do Sul State, Brazil (624,000 metric tons in 2006) can be done through a system entirely based in open-source codes.

Long-term avian research at the San Joaquin Experimental Range: Recommendations for monitoring and managing oak woodlands

Journal Articles & Books
Diciembre, 2011
América Septentrional

Experimental forests and ranges are living laboratories that provide opportunities for conducting scientific research and transferring research results to partners and stakeholders. They are invaluable for their long-term data and capacity to foster collaborative, interdisciplinary research. The San Joaquin Experimental Range (SJER) was established to develop appropriate land management practices on foothill rangelands in California. SJER has a long and rich history of avian research.

Research in geodesy and land management at the Latvia University of Agriculture

Conference Papers & Reports
Diciembre, 2013
Letonia

The paper gives an overview of the directions and results of research carried out in geodesy and land management at the Latvia University of Agriculture from the year 1939, when the Surveying Department (later the Department of Geodesy) was established, up to the present day. Since the beginnings of the Department, researches in geodesy have been associated with problems of precise levelling: vertical movements of the earth crust, deformation of buildings and structures, as well as accuracy evaluation of geodetic instruments.

Mapping ecosystem services for planning and management

Journal Articles & Books
Diciembre, 2008
Sudáfrica
África austral

This study mapped the production of five ecosystem services in South Africa: surface water supply, water flow regulation, soil accumulation, soil retention, and carbon storage. The relationship and spatial congruence between services were assessed. The congruence between primary production and these five services was tested to evaluate its value as a surrogate or proxy ecosystem service measure.

Combining asset- and species-led alien plant management priorities in the world’s most intact Mediterranean-climate landscape

Journal Articles & Books
Diciembre, 2015
Australia

Minimising the spread and impact of alien plants is a crucial component of land management for biodiversity conservation. Alien plant management typically focuses on either controlling selected alien species (‘species-led’), or on minimizing invasions within selected biodiversity or cultural assets (‘asset-led’). Here, we compare and combine species- and asset-led approaches to prioritise alien plant management activities in the world’s largest Mediterranean-climate woodland, located in south-western Australia.

Housing growth in and near United States protected areas limits their conservation value

Journal Articles & Books
Diciembre, 2010
Estados Unidos de América

Protected areas are crucial for biodiversity conservation because they provide safe havens for species threatened by land-use change and resulting habitat loss. However, protected areas are only effective when they stop habitat loss within their boundaries, and are connected via corridors to other wild areas. The effectiveness of protected areas is threatened by development; however, the extent of this threat is unknown.

Fine-scale temporal characterization of trends in soil water dissolved organic carbon and potential drivers

Journal Articles & Books
Diciembre, 2016

Long-term monitoring of surface water quality has shown increasing concentrations of dissolved organic carbon (DOC) across a large part of the Northern Hemisphere. Several drivers have been implicated including climate change, land management change, nitrogen and sulphur deposition and CO2 enrichment.

Effects of large native herbivores on other animals

Journal Articles & Books
Diciembre, 2014

Large mammalian herbivores are major drivers of the structure and function of terrestrial ecosystems world‐wide, and changes in their abundance have resulted in many populations being actively managed. Many empirical studies have identified that abundant mammalian herbivores can have negative impacts on biodiversity, but there has been no specific review of the impacts of native mammalian herbivores. We assessed the peer‐reviewed literature on the effects of large native herbivores on other animals.

The forests of the Gornji grad estate in a tradional way of husbandry and unsuccesful trials of introduction a rational forest management in the period of transition from the eighteenth to nineteenth century

Policy Papers & Briefs
Diciembre, 2009

The estate Gornji grad, since 1462 in the ownership in the diocese of Ljubljana, owned for centuries large forests and leasehold pastures. They were managaed in a traditional way with the servitude or otherwise acquired rights of the bondsmen, applying selected felling of the trees, mostly without allocation to the bondsmen or by increasing the acreage of the pasture on the expense of that of the forests as well as in many other ways. All this finally resulted, although unintentionally, in the benefit of the bondsmen.
