Suecia

The robustness of the physically-based, semi-distributed hydrological model ECOMAG with respect to changing (climatic or land-use) conditions was evaluated for two basins, considered within the modelling workshop held in the frame of the 2013 IAHS conference in Göteborg, Sweden. The first basin, the Garonne River basin, France, is characterized mostly by changes in climatic conditions, while the second, Obyån Creek, Sweden, was exposed to drastic land cover change due to deforestation.

Hydrology under change: an evaluation protocol to investigate how hydrological models deal with changing catchments

Journal Articles & Books

Suecia

Testing hydrological models under changing conditions is essential to evaluate their ability to cope with changing catchments and their suitability for impact studies. With this perspective in mind, a workshop dedicated to this issue was held at the 2013 General Assembly of the International Association of Hydrological Sciences (IAHS) in Göteborg, Sweden, in July 2013, during which the results of a common testing experiment were presented.

Long‐term change and spatial variation in butterfly communities over an elevational gradient: driven by climate, buffered by habitat

Journal Articles & Books
Diciembre, 2015
España

AIM: Efforts to adapt conservation to climate change are hampered by a scarcity of studies of community‐level ecological responses. We examined temporal (40 years) and spatial (1700 m elevational gradient) variation in butterfly communities, aiming to test whether the composition of communities in terms of species' thermal envelopes tracked regional warming, and whether local habitat influenced community responses to climate variation. LOCATION: Sierra de Guadarrama (central Spain).

Climate change and wildfire risk in an expanding wildland–urban interface: a case study from the Colorado Front Range Corridor

Estados Unidos de América

CONTEXT: Wildfire is a particular concern in the wildland–urban interface (WUI) of the western United States where human development occurs close to flammable natural vegetation. OBJECTIVES: (1) Assess the relative influences of WUI expansion versus climate-driven fire regime change on spatial and temporal patterns of burned WUI, and (2) determine whether WUI developed in the future will have higher or lower wildfire risk than existing WUI.

Biodiversity in cultural landscapes: influence of land use intensity on bird assemblages

Journal Articles & Books
Diciembre, 2015
Europa

CONTEXT: Land use changes and intensification have been amongst the major causes of the on-going biodiversity decline in Europe. A better understanding and description of how different levels of land use intensity affect biodiversity can support the planning and evaluation of policy measures. OBJECTIVES: Our study investigates how land use-related landscape characteristics affect bird diversity, considering different spatial scales and species groups with characteristic habitat use.

Monitoring prospective sites for rainwater harvesting and stormwater management in the United Kingdom using a GIS-based decision support system

Rainwater harvesting (RWH) is a practice of growing importance in the United Kingdom, particularly in the southeast of England where the water availability per person is even less than in many Mediterranean countries. Although there is a huge amount of rainfall in the north and west of England and Wales, water resources in the southeast and east of England are under pressure due to the growing population and the changing climate. Therefore, RWH becomes particularly important to reduce the dependence on the mains water supply.

Research on landscape ecological security pattern in a Eucalyptus introduced region based on biodiversity conservation

China

Landscape fragmentation and habitat loss are one of the important factors resulting in biodiversity decrease and species extinction. A large amount of Eucalyptus have been introduced into Yunnan Province in China since 2003, replaced the native forest, farmland, wasteland and other ecosystems, leading to natural habitat loss and landscape fragmentation.

Simulating streamflow on regulated rivers using characteristic reservoir storage patterns derived from synthetic remote sensing data

Journal Articles & Books
Diciembre, 2015

This study presents a method to estimate streamflow in rivers regulated by lakes or reservoirs using synthetic satellite remote sensing data. To illustrate the approach, the new reservoir routing method is integrated into the Hillslope River Routing model, and a case study is presented for the highly regulated river in the Cumberland River basin (46,400 km²). The study period is April–May 2000, which contains a significant flood event that occurred in 1–2 May 2000.

We conducted nocturnal surveys in the insular and coastal areas of Coiba National Park (CNP) and its mainland buffer zone in Panama (Chiriquí conservation site) from 2009–2012 to determine the conservation status of Crocodylus acutus. In 99 nights, we surveyed 147.2 km and captured 185 animals during nocturnal transects inspection with headlamps. Overall, sex ratio was 1.00:1.01 female/male with significant differences by size/age class and year. Females were slightly larger in total length than males (115.1 ± 56.9 cm-females, 105.4 ± 71.8 cm-males).

new approach for mapping regional land cover and the application of this approach in Australia

Australia

Detailed and accurate land cover data are widely used for various purposes, such as global land use change detection. This study aimed to investigate Australian land use and cover change by using 774 Landsat scenes in 2000 and 2010. The reference data included pictures or high-resolution images from Google Earth, global land cover data, Shuttle Radar Topography Mission data, and other literature.

Modelling long-term water yield effects of forest management in a Norway spruce forest

Intensive forest management is one of the main land cover changes over the last century in Central Europe, resulting in forest monoculture. It has been proposed that these monoculture stands impact hydrological processes, water yield, water quality and ecosystem services.

Impacts from Above-Ground Activities in the Eagle Ford Shale Play on Landscapes and Hydrologic Flows, La Salle County, Texas

We assess the spatial and geomorphic fragmentation from the recent Eagle Ford Shale play in La Salle County, Texas, USA. Wells and pipelines were overlaid onto base maps of land cover, soil properties, vegetation assemblages, and hydrologic units. Changes to continuity of different ecoregions and supporting landscapes were assessed using the Landscape Fragmentation Tool (a third-party ArcGIS extension) as quantified by land area and continuity of core landscape areas (i.e., those degraded by “edge effects”).
