A wildfire occurred in August 2000 and affected an area of 6760 ha of shrubs and cork trees, whereas still cultivated plots were only slightly affected. Five stations of erosion measurements, corresponding to five different environments (from present cultivation to late abandonment) were destroyed by the passage of fire, and were promptly replaced to allow to monitoring post-fire effects on soil erosion. Selected soil properties were determined monthly before the fire and during 6 months after the fire at a monthly rate. Runoff and sediment yield together with dissolved organic carbon (DOC) in runoff water and organic carbon losses in eroded sediments (EOC) were evaluated throughout 2000. The last stage of abandonment, stands of cork trees, had the highest soil stability. Nevertheless, evidence of unfavourable soil conditions was detected at the shrub stage, when Cistus monspeliensis cover was the dominant opportunistic plant. This stage was considered to be a critical threshold leading either to degradation or regeneration processes according to fire frequency. A drastic change in soil properties, erosion and nutrient depletion occurred after the fire in all the environments. Statistics enabled to state that environments differed significantly in main soil properties. By statistically comparing the measured variables between the environments before and after the fire, DOC was found to be the soil parameter showing the highest significance between environments. Absolute values of erosion were low with respect to other Mediterranean environments although the shallow nature of these soils might deserve special attention because of a comparatively higher risk of degradation.", "keywords": ["Analysis of Variance", "Rain", "Electric Conductivity", "04 agricultural and veterinary sciences", "Hydrogen-Ion Concentration", "15.

In this work, using a leaky integrate-and-fire neural model that includes a Ca2+-activated K+ current (IAHP), we develop a quantitative theory of adaptation temporal dynamics and compare our results with recent in vivo intracellular recordings from pyramidal cells in the cat visual cortex. Experimentally testable relations between the degree and the time constant of spike-frequency adaptation are predicted. We also contrast the IAHP model with an alternative adaptation model based on a dynamical firing threshold. Possible roles of adaptation in temporal computation are explored, as a a time-delayed neuronal self-inhibition mechanism. Our results include the following: (1) given the same firing rate, the variability of interspike intervals (ISIs) is either reduced or enhanced by adaptation, depending on whether the IAHP dynamics is fast or slow compared with the mean ISI in the output spike train; (2) when the inputs are Poisson-distributed (uncorrelated), adaptation generates temporal anticorrelation between ISIs, we suggest that measurement of this negative correlation provides a probe to assess the strength of IAHP in vivo; (3) the forward masking effect produced by the slow dynamics of IAHP is nonlinear and effective at selecting the strongest input among competing sources of input signals.", "keywords": ["0301 basic medicine", "Neurons", "03 medical and health sciences", "0302 clinical medicine", "Potassium Channels", "Time Factors", "Models", " Neurological", "Electric Conductivity", "Reaction Time", "Action Potentials", "Differential Threshold", "Calcium", "Adaptation", " Physiological"], "contacts": [{"organization": "Ying-Hui Liu, Xiao Jing Wang,", "roles": ["creator"]}]}, "links": [{"href": "https://doi.org/10.1023/a:1008916026143"}, {"rel": "related", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/Journal%20of%20computational%20neuroscience", "name": "related record", "description": "related record", "type": "application/json"}, {"rel": "self", "type": "application/geo+json", "title": "10.1023/a:1008916026143", "name": "item", "description": "10.1023/a:1008916026143", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main/items/10.1023/a:1008916026143"}, {"rel": "collection", "type": "application/json", "title": "Collection", "name": "collection", "description": "Collection", "href": "https://repository.soilwise-he.eu/cat/collections/metadata:main"}], "time": {"date": "2001-01-01T00:00:00Z"}}, {"id": "10.1371/journal.pone.0034887", "type": "Feature", "geometry": null, "properties": {"updated": "2026-07-26T16:19:19Z", "type": "Journal Article", "created": "2012-04-19", "title": "Changes In The Diversity Of Soil Arbuscular Mycorrhizal Fungi After Cultivation For Biofuel Production In A Guantanamo (Cuba) Tropical System", "description": "Open AccessLes champignons mycorhiziens arbusculaires (FMA) sont un \u00e9l\u00e9ment cl\u00e9 et int\u00e9gral de la stabilit\u00e9, de la durabilit\u00e9 et du fonctionnement des \u00e9cosyst\u00e8mes.
