High resolution global gridded data for use in population studies

  
Scientific Data, Vol. 4 (31 January 2017), 170001, https://doi.org/10.1038/sdata.2017.1

Abstract

Recent years have seen substantial growth in openly available satellite and other geospatial data layers, which represent a range of metrics relevant to global human population mapping at fine spatial scales. The specifications of such data differ widely and therefore the harmonisation of data layers is a prerequisite to constructing detailed and contemporary spatial datasets which accurately describe population distributions. Such datasets are vital to measure impacts of population growth, monitor change, and plan interventions. To this end the WorldPop Project ...

 

Stay or go - How topographic complexity influences alpine plant population and community responses to climate change

  
Perspectives in Plant Ecology, Evolution and Systematics (November 2017), https://doi.org/10.1016/j.ppees.2017.09.008

Abstract

In the face of climate change, populations have two survival options − they can remain in situ and tolerate the new climatic conditions (“stay”), or they can move to track their climatic niches (“go”). For sessile and small-stature organisms like alpine plants, staying requires broad climatic tolerances, realized niche shifts due to changing biotic interactions, acclimation through plasticity, or rapid genetic adaptation. Going, in contrast, requires good dispersal and colonization capacities. Neither the magnitude of climate change experienced locally nor the ...

 

Exploring spatial patterns and drivers of forest fires in Portugal (1980–2014)

  
Science of The Total Environment, Vol. 573 (December 2016), pp. 1190-1202, https://doi.org/10.1016/j.scitotenv.2016.03.121

Abstract

[Highlights] [::] Wildfires are irregularly distributed in Portugal, both in ignitions and burnt area. [::] In 80% of the municipality's ignition density reveal a positive trend since the 80s. [::] Geographically Weighted Regression was used to identify relevant municipal drivers of fires. [::] Topography and population density were significant factors in municipal ignitions. [::] Topography and uncultivated land were significant factors in municipal burnt area. [Abstract] Information on the spatial incidence of fire ignition density and burnt area, trends and drivers of wildfires is vitally important in providing ...

 

Scale-dependent complementarity of climatic velocity and environmental diversity for identifying priority areas for conservation under climate change

  
Global Change Biology (March 2017), https://doi.org/10.1111/gcb.13679

Abstract

As most regions of the earth transition to altered climatic conditions, new methods are needed to identify refugia and other areas whose conservation would facilitate persistence of biodiversity under climate change. We compared several common approaches to conservation planning focused on climate resilience over a broad range of ecological settings across North America and evaluated how commonalities in the priority areas identified by different methods varied with regional context and spatial scale. Our results indicate that priority areas based on different ...

 

Ecohydrology of an outbreak: mountain pine beetle impacts trees in drier landscape positions first

  
Ecohydrology, Vol. 6, No. 3. (June 2013), pp. 444-454, https://doi.org/10.1002/eco.1286

Abstract

Vegetation pattern and landscape structure intersect to exert strong control over ecohydrological dynamics at the watershed scale. The hydrologic implications of vegetation disturbance (e.g. fire, disease) depend on the spatial pattern and form of environmental change. Here, we investigate this intersection at Tenderfoot Creek Experimental Forest (TCEF), Montana, with a focus on the mountain pine beetle (Dendroctonus ponderosae) epidemic currently affecting the Rocky Mountains. We calibrated QuickBird remote sensing imagery with a leaf-level spectral library of local vegetation. We used this ...

 

Characteristics of Norway spruce trees (Picea abies) surviving a spruce bark beetle (Ips typographus L.) outbreak

  
Trees - Structure and Function In Trees, Vol. 25, No. 6. (24 May 2011), pp. 965-973, https://doi.org/10.1007/s00468-011-0571-9

Abstract

The characteristics of spruce individuals, which survived a massive bark beetle outbreak, were compared with the characteristics of neighbouring attacked trees in Šumava National Park (Czech Republic). Selected parameters related to crown geometry, stand conditions and distances between trees were measured or estimated. Significant differences were found between the surviving trees and the neighbouring trees attacked by I. typographus. Trees with a higher level of stem shading (longer crown length) tended to survive. The attacked trees were usually located in areas ...

 

Evidences of drought stress as a predisposing factor to Scots pine decline in Valle d’Aosta (Italy)

  
European Journal of Forest Research In European Journal of Forest Research, Vol. 131, No. 4. (25 October 2012), pp. 989-1000, https://doi.org/10.1007/s10342-011-0570-9

Abstract

Scots pine ( Pinus sylvestris L.) forests of many inner Alpine valleys have recently displayed a quick loss of vitality. A decline disease has been suggested as the cause, with drought as the main predisposing factor and the additional contribution of biotic agents inciting tree dieback. This study is focused on Valle d’Aosta, a dry, inner-Alpine region in NW Italy. We inferred vitality changes between years 2000 and 2007 by computing reductions in enhanced vegetation index (EVI). Image differencing was carried ...

 

Homogenization in forest performance across an environmental gradient – The interplay between rainfall and topographic aspect

  
Forest Ecology and Management, Vol. 310 (December 2013), pp. 256-266, https://doi.org/10.1016/j.foreco.2013.08.026

Abstract

[Highlights] [::] Large- and small-scale factors interact in their effect on forest performance. [::] Performance homogenization across habitats was linearly related to rainfall. [::] Homogenization was associated with drought conditions, both in time and space. [Abstract] This study aimed to investigate the interaction between local and regional environmental factors that affect forest performance during drought periods. In previous studies, contradictory results regarding the effect of aspect on forests performance, under different settings, were reported. However, each study focused on a different forest ecosystem at a different ...

 

Drought triggered tree mortality in mixed conifer forests in Yosemite National Park, California, USA

  
Forest Ecology and Management, Vol. 218, No. 1-3. (October 2005), pp. 229-244, https://doi.org/10.1016/j.foreco.2005.07.014

Abstract

Tree mortality is an important process causing forest structural and compositional change. In this study, we investigate the influence of drought and topography on recent patterns of tree mortality in old-growth mixed conifer forests in Yosemite National Park, located in the Sierra Nevada Mountains of northern California, USA. The surveyed stands have experienced a century of fire exclusion and are dominated by associations of Pinus ponderosa, Calocedrus decurrens and Abies concolor. The average age of trees in the stands was 88 ...

 

Plant-pest interactions in time and space: a Douglas-fir bark beetle outbreak as a case study

  
Landscape Ecology, Vol. 14, No. 2. (1999), pp. 105-120, https://doi.org/10.1023/a%3a1008017711917

Abstract

A conceptual model of Douglas-fir bark beetle (Dendroctonus pseudotsugae) dynamics and associated host tree mortality across multiple spatial and temporal scales was developed, then used to guide a study of the association between the occurrence of beetle- killed trees and factors that might render trees more susceptible to attack. Long-term records of beetle kill showed that beetle epidemics were associated with windstorms and drought at statewide and local spatial scales. At the landscape scale, beetle kill was associated with (i) portions ...

 

Tree and stand-level patterns and predictors of Norway spruce mortality caused by bark beetle infestation in the Tatra Mountains

  
Forest Ecology and Management, Vol. 354 (October 2015), pp. 261-271, https://doi.org/10.1016/j.foreco.2015.06.006

Abstract

This study investigates temporal shifts in Norway spruce (Picea abies) mortality, stand structure characteristics, and stand complexity facilitated by a bark beetle (Ips typographus) outbreak that affected an unmanaged subalpine forest region in Tatra National Park, Poland in the late 2000s. Changes in survivorship and stand structure characteristics (diameter (DBH), basal area, height, age, and crown length ratio) of nearly 2500 spatially-referenced trees located in 64 long-term survey plots were compared over four time periods that spanned the duration of the ...

 

Quantifying the effects of topographic aspect on water content and temperature in fine surface fuel

  
International Journal of Wildland Fire, Vol. 24, No. 8. (2015), 1129, https://doi.org/10.1071/wf14195

Abstract

This study quantifies the effects of topographic aspect on surface fine fuel moisture content (FFMC) in order to better represent landscape-scale variability in fire risk. Surface FFMC in a eucalypt forest was measured from December to May (180 days) on different aspects using a novel method for in situ monitoring of moisture content (GWClit) and temperature (Tlit) in litter. Daily mean GWClit varied systematically with aspect. North (0.07 ≤ GWClit ≤ 1.30 kg kg–1) and south (0.11 ≤ GWClit ≤ 1.83 ...

Abstract

For 11 days in February 2000, the Shuttle Radar Topography Mission (SRTM) successfully recorded by interferometric synthetic aperture radar (InSAR) data of the entire land mass of the earth between 60[degree sign]N and 57[degree sign]S. The data acquired in C- and X-bands are processed into the first global digital elevation models (DEMs) at 1 arc sec resolution, by NASA-JPL and German aerospace center (DLR), respectively. From the perspective of the SRTM-X system, we give in this paper an overview of the ...

 

A bottom-up control on fresh-bedrock topography under landscapes

  
Proceedings of the National Academy of Sciences, Vol. 111, No. 18. (06 May 2014), pp. 6576-6581, https://doi.org/10.1073/pnas.1404763111

Abstract

[Significance] Hilly landscapes are typically mantled with soil and underlain by a weathered bedrock zone that may extend tens of meters beneath the surface before reaching fresh bedrock. The weathered bedrock zone influences water runoff to channels, the chemistry of that water, the rates and processes of erosion, and atmospheric processes due to plant uptake of moisture and return to the atmosphere. However, the spatial pattern of the underlying fresh-bedrock surface is essentially unknown. We present a testable model that predicts ...

 

Assessment of fire selectivity in relation to land cover and topography: a comparison between Southern European countries

  
International Journal of Wildland Fire (2013), https://doi.org/10.1071/wf12053

Abstract

Land cover distribution is one of the factors that influence fire behaviour and its consequences in the landscape. The relation between land cover type and fire was investigated at a broad scale, in order to analyse land cover differences in fire proneness. The selection ratio for nine different land cover categories was calculated for the fire perimeters mapped in Southern Europe between 2000 and 2008. The results obtained were then compared per country and region. The fire proneness of topographic classes ...

 

Hillslopes Record the Growth and Decay of Landscapes

  
Science, Vol. 341, No. 6148. (23 August 2013), pp. 868-871, https://doi.org/10.1126/science.1241791

Abstract

Earth's surface archives the combined history of tectonics and erosion, which tend to roughen landscapes, and sediment transport and deposition, which smooth them. We analyzed hillslope morphology in the tectonically active Dragon’s Back Pressure Ridge in California, United States, to assess whether tectonic uplift history can be reconstructed using measurable attributes of hillslope features within landscapes. Hilltop curvature and hillslope relief mirror measured rates of vertical displacement caused by tectonic forcing, and their relationships are consistent with those expected when idealizing ...

Parametric study of an eruptive fire behaviour model

  
International Journal of Wildland Fire, Vol. 15, No. 2. (2006), 169, https://doi.org/10.1071/wf05050

Abstract

The application of a mathematical model to predict dynamic fire behaviour with different types of fuels is explored. This model predicts the occurrence of eruptive fire behaviour that is observed mainly in steep slopes and canyons. The practical range of the parameters involved in the model is estimated and their average values for four main fuel types are presented. The predicted differences in dynamic fire behaviour between light and heavy fuels are justified by observations. Given the importance of time as ...
