Spatial distribution of citizen science casuistic observations for different taxonomic groups

Scientific Reports, Vol. 7, No. 1. (16 October 2017),


Opportunistic citizen science databases are becoming an important way of gathering information on species distributions. These data are temporally and spatially dispersed and could have limitations regarding biases in the distribution of the observations in space and/or time. In this work, we test the influence of landscape variables in the distribution of citizen science observations for eight taxonomic groups. We use data collected through a Portuguese citizen science database ( We use a zero-inflated negative binomial regression to model the distribution ...


The uncertain nature of absences and their importance in species distribution modelling

Ecography, Vol. 33, No. 1. (1 February 2010), pp. 103-114,


Species distribution models (SDM) are commonly used to obtain hypotheses on either the realized or the potential distribution of species. The reliability and meaning of these hypotheses depends on the kind of absences included in the training data, the variables used as predictors and the methods employed to parameterize the models. Information about the absence of species from certain localities is usually lacking, so pseudo-absences are often incorporated to the training data. We explore the effect of using different kinds of ...


Meta-analysis of field experiments shows no change in racial discrimination in hiring over time

Proceedings of the National Academy of Sciences, Vol. 114, No. 41. (10 October 2017), pp. 10870-10875,


[Significance] Many scholars have argued that discrimination in American society has decreased over time, while others point to persisting race and ethnic gaps and subtle forms of prejudice. The question has remained unsettled due to the indirect methods often used to assess levels of discrimination. We assess trends in hiring discrimination against African Americans and Latinos over time by analyzing callback rates from all available field experiments of hiring, capitalizing on the direct measure of discrimination and strong causal validity of these ...


Describing wildland surface fuel loading for fire management: a review of approaches, methods and systems

International Journal of Wildland Fire, Vol. 22, No. 1. (2013), 51,


Wildland fuelbeds are exceptionally complex, consisting of diverse particles of many sizes, types and shapes with abundances and properties that are highly variable in time and space. This complexity makes it difficult to accurately describe, classify, sample and map fuels for wildland fire research and management. As a result, many fire behaviour and effects software prediction systems use a generalised description of fuels to simplify data collection and entry into various computer programs. There are several major fuel description systems currently ...


Post-fire erosion response in a watershed mantled by volcaniclastic deposits, Sarno Mountains, Southern Italy

CATENA, Vol. 152 (May 2017), pp. 227-241,


[Highlights] [::] We describe a post-fire erosion response of a steep watershed in Italy. [::] The fire burned 11 ha of forest with high and moderate severity. [::] The erosion response was triggered by a convective rainstorm. [::] A hyperconcentrated flow resulted from sediment bulking of surface runoff. [::] Amount of soil loss was estimated. [Abstract] In this study we document a post-fire erosion response to a short-lived, intense rainstorm occurred on 6 September 2012 in the Sant'Angelo creek watershed, Sarno Mountains, Southern Italy. The rainstorm occurred one ...

The most comprehensive dataset of in situ destructive sampling measurements of forest biomass in Eurasia have been compiled from a combination of experiments undertaken by the authors and from scientific publications. Biomass is reported as four components: live trees (stem, bark, branches, foliage, roots); understory (above- and below ground); green forest floor (above- and below ground); and coarse woody debris (snags, logs, dead branches of living trees and dead roots), consisting of 10,351 unique records of sample plots and 9,613 sample ...


Modeling the probability of resource use: the effect of, and dealing with, detecting a species imperfectly

Journal of Wildlife Management, Vol. 70, No. 2. (1 April 2006), pp. 367-374,[367:mtporu];2


Resource-selection probability functions and occupancy models are powerful methods of identifying areas within a landscape that are highly used by a species. One common design/analysis method for estimation of a resource-selection probability function is to classify a sample of units as used or unused and estimate the probability of use as a function of independent variables using, for example, logistic regression. This method requires that resource units are correctly classified as unused (i.e., the species is never undetected in a used ...

Ground-truthing the Drought Code: field verification of overwinter recharge of forest floor moisture

Vol. 268 (1996)


[Excerpt:Executive summary] Users of the Canadian Forest Fire Weather Index System are required to precede computation of the Drought Code (DC) component each spring by first calculating a mathematical model of overwinter recharge of moisture in the forest floor. Practical limitations of the mathematical model, required for operational simplicity, have resulted in requests from users for a field sampling procedure that can be used to verify the model, where, and when desired. [\n] This report describes a standard procedure for destructively sampling ...


Assessing live fuel moisture for fire management applications

In Fire in ecosystem management: shifting the paradigm from suppression to prescription, Vol. 20 (1998), pp. 49-55


The variation associated with sampling live fuel moisture was examined for several shrub and canopy fuels in southern California, Arizona, and Colorado. Ninety-five % confidence intervals ranged from 5 to % . Estimated sample sizes varied greatly. The value of knowing the live fuel moisture content in fire decision making is unknown. If the fuel moisture is highly variable, then it is possible for the confidence intervals to span one or more fire behavior or danger classes. Errors in live fuel ...

The International Plant Sentinel Network: a tool for regional and national plant protection organizations

EPPO Bulletin, Vol. 46, No. 1. (April 2016), pp. 156-162,


[Excerpt:Introduction] A 2011 global survey of botanic gardens and arboreta, which included 204 respondents from 146 institutes, revealed that the botanic garden community has the potential to play a significant role in safeguarding plant health. However, responding institutes cited a lack of available training, resources and coordination to support any such work (Kramer & Hird 2011). Since its launch in November 2013, the International Plant Sentinel Network (IPSN) has been working to provide this support and illustrate the usefulness of such a ...


Intercomparison of MODIS albedo retrievals and in situ measurements across the global FLUXNET network

Remote Sensing of Environment, Vol. 121 (June 2012), pp. 323-334,


[Abstract] Surface albedo is a key parameter in the Earth's energy balance since it affects the amount of solar radiation directly absorbed at the planet surface. Its variability in time and space can be globally retrieved through the use of remote sensing products. To evaluate and improve the quality of satellite retrievals, careful intercomparisons with in situ measurements of surface albedo are crucial. For this purpose we compared MODIS albedo retrievals with surface measurements taken at 53 FLUXNET sites that met strict ...


Estimate of the (R)USLE rainfall erosivity factor from monthly precipitation data in mainland Spain

Journal of Iberian Geology, Vol. 42, No. 1. (07 June 2016),


The need for continuous recording rain gauges makes it difficult to determine the rainfall erosivity factor (R-factor) of the (R)USLE model in areas without good temporal data coverage. In mainland Spain, the Nature Conservation Institute (ICONA) determined the R-factor at few selected pluviographs, so simple estimates of the R-factor are definitely of great interest. The objectives of this study were: (1) to identify a readily available estimate of the R-factor for mainland Spain; (2) to discuss the applicability of a single ...


Comparison between the USLE, the USLE-M and replicate plots to model rainfall erosion on bare fallow areas

CATENA, Vol. 145 (October 2016), pp. 39-46,


[Highlights] [::] Examines ability of soil losses from a plot to predict those from another [::] Stochastic and systemic variations observed when replicate model used [::] Replicate model tends to perform better that USLE-M when runoff known. [Abstract] It has been proposed that the best physical model of erosion from a plot is provided by a replicate plot (Nearing, 1998). Event data from paired bare fallow plots in the USLE database were used to examine the abilities of replicate plots, the USLE and the USLE-M to ...


Impacts of uncertainties in European gridded precipitation observations on regional climate analysis

Int. J. Climatol., Vol. 37, No. 1. (1 March 2017), pp. 305-327,


Gridded precipitation data sets are frequently used to evaluate climate models or to remove model output biases. Although precipitation data are error prone due to the high spatio-temporal variability of precipitation and due to considerable measurement errors, relatively few attempts have been made to account for observational uncertainty in model evaluation or in bias correction studies. In this study, we compare three types of European daily data sets featuring two Pan-European data sets and a set that combines eight very high-resolution ...


The role of European National Forest Inventories for international forestry reporting

Annals of Forest Science, Vol. 73, No. 4. (2016), pp. 793-806,


[Key message] Despite agreements on definitions, the national data provided for international reporting are lacking comparability. To address this limitation the European National Forest Inventory Network has established criteria to harmonise definitions and to provide tools to transform national data into internationally comparable data. [Context] Forest reporting presents a series of challenges for countries, owing to diverse processes at international level such as the Global Forest Resources Assessment (FRA), Convention on Biological Diversity, United Nations Framework Convention on Climate Change and its Kyoto Protocol. ...


Killer landslides: the lasting legacy of Nepal's quake

Nature, Vol. 532, No. 7600. (25 April 2016), pp. 428-431,


A year after a devastating earthquake triggered killer avalanches and rock falls in Nepal, scientists are wiring up mountainsides to forecast hazards. [Excerpt] [...] “It’s a real problem for reconstruction,” says Tara Nidhi Bhattarai, a geologist at Tribhuvan University in Kathmandu and chief scientist of Nepal’s National Reconstruction Authority — an agency established last year to manage the recovery efforts. “What are the safe places to rebuild, in a landscape that is evolving?” [\n] To answer that, geoscientists are wiring up the mountains ...

[\n] With continuously increasing international agreements and commitments, the need for information has also grown drastically, and reporting requests have become more frequent and the content of the ...


Erosion in Mediterranean landscapes: changes and future challenges

Geomorphology, Vol. 198 (September 2013), pp. 20-36,


[Highlights] [::] Recent land uses contribute to soil erosion in marginal lands. [::] Long history of human activity explains many landscape characteristics. [::] Intensification and extensification/wealth and poverty increase spatial complexity. [Abstract] Intense erosion processes are widespread in the Mediterranean region, and include sheet wash erosion, rilling, gullying, shallow landsliding, and the development of large and active badlands in both subhumid and semi-arid areas. This review analyses the main environmental and human features related to soil erosion processes, and the main factors that explain the extreme ...


The use of terrestrial LiDAR technology in forest science: application fields, benefits and challenges

This article aims to establish the state-of-the-art in this emerging area. [Objectives] Terrestrial LiDAR has been applied to forest inventory measurements (plot cartography, species recognition, diameter at breast height, tree height, stem density, basal area and plot-level wood volume estimates) and canopy characterisation (virtual ...


Caractérisation des pluies en Belgique du point de vue de leur intensité et de leur érosivité

Pedologie, Vol. 28, No. 2. (1978), pp. 214-232


[Excerpt: Introduction] Aux Etats-Unis, l'attention des chercheurs a été attirée depuis longtemps déjà sur les conséquences catastrophiques que pouvait engendrer l'érosion des sols. Depuis l'entre-deux-guerres des moyens, très importants en hommes et en matériel, ont été mis en oeuvre dans Ie but de déterminer les facteurs qui causent ou favorisent l'érosion et les techniques qui sont susceptibles de la freiner. . Ces recherches ont notamment abouti à l'élaboration d'un modèle mathématique de l'érosion, désigné sous Ie vocable de "Universa! soil-Ioss equation" (W. H. Wischmeier & D. D. Smith, 1960, 1962, 1965), bien ...


The climate of Europe during the Holocene: a gridded pollen-based reconstruction and its multi-proxy evaluation

Quaternary Science Reviews, Vol. 112 (March 2015), pp. 109-127,


[Highlights] [::] We reconstruct the climate of Europe during the Holocene from pollen data. [::] The data is presented as gridded maps at 1000 year time intervals. [::] The reconstruction is evaluated against those from other proxies/studies. [::] Generally good agreement is shown apart from with Chironomids. [::] Results indicate greater warming in winter than in summer over Northern Europe. [Abstract] We present a new gridded climate reconstruction for Europe for the last 12,000 years based on pollen data. The reconstruction is an update of Davis et ...


Atmospheric composition 1 million years ago from blue ice in the Allan Hills, Antarctica

Proceedings of the National Academy of Sciences, Vol. 112, No. 22. (02 June 2015), pp. 6887-6891,


[Significance] Bubbles of ancient air trapped in ice cores permit the direct reconstruction of atmospheric composition and allow us to link greenhouse gases and global climate over the last 800 ky. Here, we present new ice core records of atmospheric composition roughly 1 Ma from a shallow ice core drilled in the Allan Hills blue ice area, Antarctica. These records confirm that interglacial CO2 concentrations decreased by 800 ka. They also show that the link between CO2 and Antarctic temperature extended into ...


Tree-rings reflect the impact of climate change on Quercus ilex L. along a temperature gradient in Spain over the last 100 years

Forest Ecology and Management, Vol. 262, No. 9. (November 2011), pp. 1807-1816,


[Highlights] [::] We study the oak response to climate along a temperature gradient using tree-rings. [::] Stand competition history was reconstructed and growth trends discussed. [::] Just warmer stands have reduced productivity responding to water stress increase. [::] The relationship between growth and precipitation was non-linear (sigmoidal). [::] The sigmoid response reflected biogeographically meaningful thresholds. [Abstract] We analyzed tree rings over the past 100 years to understand the response of Quercus ilex L. to climate change at four different sites along a temperature gradient in a highly ...


Coppice abandonment and its implications for species diversity in forest vegetation

Forest Ecology and Management, Vol. 343 (May 2015), pp. 88-100,


Coppicing, once common in broadleaved forests, was mostly abandoned after WWII. We investigated long-term changes in both woody and herbaceous species composition. The impact of coppice abandonment on vegetation composition was evaluated. Conservation value of forests reduced considerably after the coppice abandonment. To stop biodiversity loss, we propose the re-establishment of coppice management. Coppicing, once a common type of management in European broadleaved forests, was abandoned in many places after WWII. This form of management provided a variety of structural and ...


Increasing drought under global warming in observations and models

Nature Climate Change, Vol. 3, No. 1. (5 August 2012), pp. 52-58,


Historical records of precipitation, streamflow and drought indices all show increased aridity since 1950 over many land areas1, 2. Analyses of model-simulated soil moisture3, 4, drought indices1, 5, 6 and precipitation-minus-evaporation7 suggest increased risk of drought in the twenty-first century. There are, however, large differences in the observed and model-simulated drying patterns1, 2, 6. Reconciling these differences is necessary before the model predictions can be trusted. Previous studies8, 9, 10, 11, 12 show that changes in sea surface temperatures have large ...


Formal definition and dating of the GSSP (Global Stratotype Section and Point) for the base of the Holocene using the Greenland NGRIP ice core, and selected auxiliary records

Journal of Quaternary Science, Vol. 24, No. 1. (January 2009), pp. 3-17,


The Greenland ice core from NorthGRIP (NGRIP) contains a proxy climate record across the Pleistocene-Holocene boundary of unprecedented clarity and resolution. Analysis of an array of physical and chemical parameters within the ice enables the base of the Holocene, as reflected in the first signs of climatic warming at the end of the Younger Dryas/Greenland Stadial 1 cold phase, to be located with a high degree of precision. This climatic event is most clearly reflected in an abrupt shift in deuterium ...


Evaluation of modelled spatially distributed predictions of soil erosion by water versus field-based assessments

Environmental Science & Policy, Vol. 8, No. 5. (October 2005), pp. 493-501,


Policy makers concerned about soil erosion and its impacts need good quality information on which to base their decisions. There is a trend toward using erosion models to aid such decision making. Such models are based on data obtained from experimental plots. The theoretical results need to be compared with information gained from monitoring erosion in the field to assess if theory accords with reality. Data from the Minimum Information Requirement version of the Water Erosion Prediction Project model (MIRSED) are ...

Identifying and modelling environmental indicators for assessing population vulnerability to conflict using ground and satellite data

Ecological Indicators, Vol. 10, No. 2. (23 March 2010), pp. 493-503,


Conflicts may be directly responsible for the modification of features in the landscape by causing damage to built-up areas or to the environment. Landscape features may also be indirectly affected by conflict as the result of changes in the way of life of inhabitants and their use of natural resource. Conflict-induced changes in landuse features may thus be associated with changes in population vulnerability. This study focuses on the environmental indicators for population vulnerability, an important parameter contributing to risk assessment ...


Establishing forest inventory reference definitions for forest and growing stock: a study towards common reporting

Silva Fennica, Vol. 42, No. 2. (2008),


International agreements such as the Kyoto protocol and Convention on Biological Diversity (1992), as well as, criteria and indicator processes require reports on the status of nations’ forests. Any comparison of the current status and trends of forest resources among nations presumes that the nations’ applied definitions and concepts produce comparable estimates of the status of forests. In spite of this, the FAO has already collected global information for 60 years and made noticeable efforts in creating common definitions, but forest ...



In National forest inventories - Pathways for common reporting (2010), pp. 1-18,


The history of forest inventories goes back to the end of the Middle Ages when intensive use of forest resources first led to wood shortages which, in turn, forced users to begin forest planning, particularly near towns and mines (Loetsch and Haller 1973; Gabler and Schadauer 2007). The first information collected for these purposes was from assessments of forest area and crude estimates of growing stock. [\n] As a noun, the word ‘inventory’ refers to a detailed list of articles according to ...

A large-scale field assessment of carbon stocks in human-modified tropical forests

Glob Change Biol (1 May 2014), pp. n/a-n/a,


Tropical rainforests store enormous amounts of carbon, the protection of which represents a vital component of efforts to mitigate global climate change. Currently, tropical forest conservation, science, policies, and climate mitigation actions focus predominantly on reducing carbon emissions from deforestation alone. However, every year vast areas of the humid tropics are disturbed by selective logging, understory fires, and habitat fragmentation. There is an urgent need to understand the effect of such disturbances on carbon stocks, and how stocks in disturbed forests ...


Erodibility Indices Compared to Measured Values of Selected Trinidad Soils

Soil Science Society of America Journal, Vol. 46, No. 2. (1982), 393,


The most suitable erodibility index for tropical soils has not been determined. This study was therefore carried out with 10 selected Trinidad soils to compare three erodibility indices previously used with soils in different parts of the world. The erodibility of the soils was determined by the USDA Erodibility Nomograph, the Australian Erodibility Index, and the Modified Raindrop Technique and their suitability evaluated by comparison with the erodibility measured directly on four of the 10 soil types in the field. The USDA ...


Soil erodibility and its estimation for agricultural soils in China

Journal of Arid Environments, Vol. 72, No. 6. (June 2008), pp. 1002-1011,


Soil erodibility (the K factor in the Universal Soil Loss Equation, USLE) is an important index to measure soil susceptibility to water erosion, and an essential parameter needed for soil erosion prediction. To evaluate the appropriateness of the nomograph and other methods for estimating the K factor for the USLE and to develop a relationship for soil erodibility estimation for Chinese soils, a set of soil erodibility values was calculated using soil loss data from natural runoff plots at 13 sites ...


Carbon concentrations and stocks in forest soils of Europe

Forest Ecology and Management, Vol. 260, No. 3. (30 June 2010), pp. 262-277,


This study presents the results of a series of evaluations of a continent-wide soil database (EU/UN-ECE Level I) with the aim to estimate baseline soil carbon concentrations and stocks. The methodology included the biogeographic stratification of soil carbon measurements throughout Europe using climatic zones derived from the Soil Regions Map of Europe. The presented stock estimates range from 1.3 to 70.8 t C/ha for the O-layer, and from 11.3 to 126.3 t C/ha for the mineral soil 0–20 cm (Germany: 0–30 cm) (5 and 95 percentiles). Histosols ...

A 3,500-year tree-ring record of annual precipitation on the northeastern Tibetan Plateau

Proceedings of the National Academy of Sciences, Vol. 111, No. 8. (25 February 2014), pp. 2903-2908,


[Significance] This paper describes the production and climatic interpretation of a tree-ring width chronology that is currently the longest, absolutely dated series produced for the northeastern Tibetan Plateau and one of the longest in the world. The method of chronology construction enables comparison of variations in precipitation totals over long timescales as well as shorter periods. Precipitation in this region during the last 50 years has been historically high—likely higher than for any equivalent length period in at least 3,500 years, ...


Soil erosion in the Swiss midlands: results of a 10-year field survey

Geomorphology, Vol. 126, No. 1-2. (26 March 2011), pp. 32-41,


Long-term field monitoring of soil erosion by water was conducted on arable land in the Swiss midlands. All visible erosion features in 203 fields were continuously mapped and quantified over 10 years. The eroded soil volume associated with linear erosion features was calculated by measuring the length and cross-sectional area in rills at representative positions and the extent of interrill erosion was estimated. Averaged across the 10 study years, just under one-third (32.2%) of the fields exhibited erosion. With 0.75 t ha−1 yr−1 ...


Measuring the accuracy of species distribution models: a review

In 18th World IMACS Congress and MODSIM09 International Congress on Modelling and Simulation (July 2009), pp. 4241-4247


Species distribution models (SDMs) are empirical models relating species occurrence to environmental variables based on statistical or other response surfaces. Species distribution modeling can be used as a tool to solve many theoretical and applied ecological and environmental problems, which include testing biogeographical, ecological and evolutionary hypotheses, assessing species invasion and climate change impact, and supporting conservation planning and reserve selection. The utility of SDM in real world applications requires the knowledge of the model's accuracy. The accuracy of a model ...


Assessing the accuracy of land cover change with imperfect ground reference data

Remote Sensing of Environment, Vol. 114, No. 10. (19 October 2010), pp. 2271-2285,


The ground data used as a reference in the validation of land cover change products are often not an ideal gold standard but degraded by error. The effects of ground reference data error on the accuracy of land cover change detection and the accuracy of estimates of the extent of change were evaluated. Twelve data sets were simulated to allow the exploration of the impacts of a spectrum of ground data imperfections on the estimation of the producer's and user's accuracy ...

Meta-information Database (INRMM-MiD).
This database integrates a dedicated meta-information database in CiteULike (the CiteULike INRMM Group) with the meta-information available in Google Scholar, CrossRef and DataCite. The Altmetric database with Article-Level Metrics is also harvested. Part of the provided semantic content (machine-readable) is made even human-readable thanks to the DCMI Dublin Core viewer. Digital preservation of the meta-information indexed within the INRMM-MiD publication records is implemented thanks to the Internet Archive.
