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

Journal Articles & Books
Décembre, 2011
Amérique septentrionale

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
Décembre, 2013
Lettonie

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
Décembre, 2008
Afrique du Sud
Afrique australe

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.

Hydrological modelling of drained blanket peatland

Journal Articles & Books
Décembre, 2011

Open ditch drainage is a commonly implemented land management practice in upland blanket peatlands, particularly in the UK, where policy decisions between the 1940s and 1970s led to widespread drainage of the uplands. The change in the hydrological regime associated with the drainage of blanket peat is poorly understood, yet has perceived importance for flooding, low flows and water quality. We propose a new simplified physics-based model that allows the associated hydrological processes and flow responses to be explored.

Multi‐Taxa Assessment of Biodiversity Change After Single and Recurrent Wildfires in a Brazilian Amazon Forest

Journal Articles & Books
Décembre, 2016

In the last decades, due to human land management that uses fire as a tool, and due to abnormal droughts, many tropical forests have become more susceptible to recurrent wildfires with negative consequences for biodiversity. Yet, studies are usually focused on few taxa and rarely compare different fire frequencies. We examined if the effects of single and recurrent fires are consistent for leaf litter ants, dung beetles, birds (sampled with point‐counts PC and mist net‐MN), saplings, and trees.

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

Journal Articles & Books
Décembre, 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
Décembre, 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
Décembre, 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.

Scale effects on the estimation of erosion thresholds through a distributed and physically-based hydrological model

Journal Articles & Books
Décembre, 2012

Slope incision and subsequent development of rills, gullies and channels are responsible for significant soil losses and are often irreversible with very high restoration costs particularly in semiarid environments. The location of potential areas of erosion where these processes occur is vital to land management and conservation.
