Anthropogenic Landscapes, Human Action and the Process of Co-Construction with other Species: Making Anthromes in the Anthropocene

Peer-reviewed publication
Marzo, 2017
Etiopía

We are in the Anthropocene. For millennia, human actions have been shaping the world to the degree that they are inscribed in the geological and ecological record. Recently, this has been occurring with increasing speed and influence. This means we need to be asking integrative and effective questions about the world and how we relate to and in it. Human niche construction has broad and deep effects not just on landscapes and environments, but on the myriad of other beings sharing space with us.

Valuation of Ecosystem Services from Wetlands Mitigation in the United States

Peer-reviewed publication
Marzo, 2015

Section 404 of the U.S. Clean Water Act includes most wetlands in its jurisdiction and requires wetland mitigation to compensate for permitted wetland losses. These mitigation wetlands can provide ecosystem services similar to original wetlands if properly constructed. Improvement of wetland monitoring requirements coupled with economic assessment is critical for effective implementation of the mitigation policy. The economic assessment when left out of evaluation of mitigation policy could result in mitigation wetlands being given too little weight in policy decisions.

Terrestrial Species in Protected Areas and Community-Managed Lands in Arunachal Pradesh, Northeast India

Peer-reviewed publication
Diciembre, 2016
India

Protected areas (including areas that are nominally fully protected and those managed for multiple uses) encompass about a quarter of the total tropical forest estate. Despite growing interest in the relative value of community-managed lands and protected areas, knowledge about the biodiversity value that each sustains remains scarce in the biodiversity-rich tropics. We investigated the species occurrence of a suite of mammal and pheasant species across four protected areas and nearby community-managed lands in a biodiversity hotspot in northeast India.

Why Landscape Beauty Matters

Peer-reviewed publication
Diciembre, 2014

This philosophical paper explores the aesthetic argument for landscape conservation. The main claim is that the experience of beautiful landscapes is an essential part of the good human life. Beautiful landscapes make us feel at home in the world. Their great and irreplaceable value lies therein. To establish this claim, the concepts of landscape and “Stimmung” are clarified. It is shown how “Stimmung” (in the sense of mood) is infused into landscape (as atmosphere) and how we respond to it aesthetically. We respond by resonating or feeling at home.

Translocation of Cd and Mn from Bark to Leaves in Willows on Contaminated Sediments: Delayed Budburst Is Related to High Mn Concentrations

Peer-reviewed publication
Junio, 2015

Changes in the hydrology of sediments in tidal marshes or landfills may affect the uptake of metals in the vegetation. Leaf and stem samples of Salix cinerea (grey sallow) were collected during four consecutive growing seasons at six contaminated plots on a polluted dredged sediment landfill and one plot on an uncontaminated reference site. The first three contaminated plots were already emerged in the first half of the first growing season, while the other three were submerged in the first year, but became increasingly dry over the study period.

Exploring Long-Term Impact of Grazing Management on Land Degradation in the Socio-Ecological System of Asteroussia Mountains, Greece

Peer-reviewed publication
Septiembre, 2015

The socio-ecological system dominated by pastureland in the Asteroussia Mountains (Crete, Greece) was analyzed over a long time interval (1945–2010) to identify the most relevant system’s characteristics and changes. Vegetation cover and land-uses have been quantified by analyzing aerial photographs exploring the whole study period. Soil characteristics have been assessed by carrying out an extensive field survey for the last reference year (2010) and by estimating the average soil loss for the past period using the PESERA soil erosion model validated by field measurements.

The Role of Citizen Science in Landscape and Seascape Approaches to Integrating Conservation and Development

Peer-reviewed publication
Diciembre, 2015

Initiatives to manage landscapes for both biodiversity protection and sustainable development commonly employ participatory methods to exploit the knowledge of citizens. We review five examples of citizen groups engaging with landscape scale conservation initiatives to contribute their knowledge, collect data for monitoring programs, study systems to detect patterns, and test hypotheses on aspects of landscape dynamics. Three are from landscape interventions that deliberately target biodiversity conservation and aim to have sustainable development as a collateral outcome.

Building Bridges across Sectors and Scales: Exploring Systemic Solutions towards A Sustainable Management of Land —Experiences from 4th Year Status Conference on Research for Sustainable Land Management

Peer-reviewed publication
Junio, 2015

Interacting land use demands and competing interests originating from fields such as agriculture, housing, mobility and nature conservation call for integrated governance approaches that incorporate disciplinary perspectives and arbitrate between them. The German research program “Sustainable Land Management” targets this challenge and provides an umbrella for a number of regional projects involving transdisciplinary system-oriented approaches to sustainable land use, connecting researchers and practitioners.

Restoration of Prairie Hydrology at the Watershed Scale: Two Decades of Progress at Neal Smith National Wildlife Refuge, Iowa

Peer-reviewed publication
Marzo, 2014

Tallgrass prairie once occupied 67.6 million hectares in the North American Midwest but less than 0.1% remains today. Consisting of more than 2200 ha, Neal Smith National Wildlife Refuge (NSNWR) was established by the US Fish and Wildlife Service in the 5217 ha Walnut Creek watershed in Jasper County, Iowa. Large tracts of land are being converted from row crop agriculture to native prairie and savanna with the goal to restore the landscape to a semblance of the condition that existed prior to Euro-American settlement.

Patterns and Predictors of Recent Forest Conversion in New England

Peer-reviewed publication
Septiembre, 2016

New England forests provide numerous benefits to the region’s residents, but are undergoing rapid development. We used boosted regression tree analysis (BRT) to assess geographic predictors of forest loss to development between 2001 and 2011. BRT combines classification and regression trees with machine learning to generate non-parametric statistical models that can capture non-linear relationships.

Accounting for the Drivers that Degrade and Restore Landscape Functions in Australia

Peer-reviewed publication
Diciembre, 2016

Assessment and reporting of changes in vegetation condition at site and landscape scales is critical for land managers, policy makers and planers at local, regional and national scales. Land management, reflecting individual and collective values, is used to show historic changes in ecosystem structure, composition and function (regenerative capacity). We address the issue of how the resilience of plant communities changes over time as a result of land management regimes.

Historical and Contemporary Geographic Data Reveal Complex Spatial and Temporal Responses of Vegetation to Climate and Land Stewardship

Peer-reviewed publication
Junio, 2013

Vegetation and land-cover changes are not always directional but follow complex trajectories over space and time, driven by changing anthropogenic and abiotic conditions. We present a multi-observational approach to land-change analysis that addresses the complex geographic and temporal variability of vegetation changes related to climate and land use.
