Abstract The Yungas, a system of tropical and subtropical montane forests on the eastern slopes of the Andes, are extremely diverse and severely threatened by anthropogenic pressure and climate change. Previous mycological works focused on macrofungi (e.g. agarics, polypores) and mycorrhizae in Alnus acuminata forests, while fungal diversity in other parts of the Yungas has remained mostly unexplored. We carried out Ion Torrent sequencing of ITS2 rDNA from soil samples taken at 24 sites along the ...

Abstract Questions What changes have occurred in M editerranean high‐mountain communities during the last 50 yr? Do these changes reflect upward shifts and decline in dry grassland specialists due to climate warming? Location Upper belt (1900–2400 m a.s.l.) in S ierra de G uadarrama, S pain. Methods We re‐surveyed dry grassland communities in 50 summits that were previously sampled between the 1960s and 1980s.

Ecological niche models represent key tools in biogeography but the effects of biased sampling hinder their use. Here, we address the utility of two forms of filtering the calibration data set (geographic and environmental) to reduce the effects of sampling bias. To do so we created a virtual species, projected its niche to the Iberian Peninsula and took samples from its binary geographic distribution using several biases. We then built models for various sample sizes after applying each of the filtering ...

We had the opportunity to study a family, five of whose members were affected by the Hallervorden‐Spatz disease (three males and twin girls). The characteristics of the condition were analyzed and compared with those cases considered by other authors to be affected by the condition. Intrafamilial and interfamilial variations were analysed, and it was the latter that contributed most to the overall variation of the condition. It was clearly established from the reported cases and our family that this ...

The hydraulic conductivity, k, of clayey soils is strongly influenced by the physicochemical properties of permeating liquid hydrocarbons. Tests on natural Sarnia soils mixed with pure liquids at a void ratio of 0.8 yielded k values that increased from 5 × 10 −9 to 1 × 10 −4 cm/s as the dielectric constant of the permeant decreased from 80 to 2.Sequential permeation of compacted, water-wet samples (k ≈ 10 −8 cm/s) showed no changes in hydraulic conductivity when permeated with water-insoluble hydrocarbons ...

The hydraulic conductivity of natural clays in the 1.5 m contamination zone below a 15 year old domestic waste landfill has been determined.Water-soluble contaminants such as chloride, sodium, and dissolved organic carbon have migrated about 1.0 m compared with only 15 cm for copper, zinc, iron, lead, and manganese. The migration, primarily by diffusion, has rendered the clay perfect for assessment of clay–leachate compatibility with respect to hydraulic conductivity, k.Oedometer tests on tube samples ...

Water-soluble organic liquids may, under some circumstances, dramatically increase the hydraulic conductivity, k, of water-saturated clayey soils, thus destroying their effectiveness as barriers for contaminants. Double-layer contraction at constant void ratio with resultant increases in the pore space available for flow has been identified as a primary mechanism for such increases in k. This paper shows, however, that the increased viscosity of solutions of some organics in water results in significant ...

The current use of engineered clayey barriers to control the chemical flux entering the groundwater adjacent to landfill sites is discussed. New analytical methods to predict flux–time relationships controlled by advection and diffusion are presented briefly, followed by an assessment of macropore flow problems inherent in laboratory and especially field-compacted clays.The clay–leachate compatability of southern Ontario (Sarnia) clays is then assessed with respect to domestic waste leachate using ...

The magnitude of the effective stresses acting on a clay barrier appear to play a critical role in preserving low hydraulic conductivity, k, during exposure to soluble organic liquids. This paper summarizes the results of a research study on a natural clay from southwestern Ontario permeated with various mixtures of landfill leachate and water-soluble organic liquids at effective stresses ranging from 0 to ~300 kPa. Laboratory testing of "unconfined", water-compacted clays indicated that municipal ...

Abstract. In heavily altered landscapes, where vegetation is not natural and where people are the main source of ignitions, relationships between fire occurrence and climate conditions may be unclear. The objective of this study was to evaluate to what extent territories with similar Potential Natural Vegetation (PNV) in peninsular Spain differ in their forest fire characteristics. From 1974 to 1994, more than 174 000 fires occurred. We used (1) the Spanish data base of forest fires, (2) a PNV map ...

Land-use change has been one of the main drivers of landscape changes in the Mediterranean region during the last decades. Many of the formerly intensively cultivated or grazed areas were converted to forest and wilderness through afforestation or abandonment. Understanding the threats to such lands in their process of recovery to less intensively managed systems is important to have a proper understanding of the effects of land-use change on the ecosystem. Our aim was to determine how land-use ...

Abstract This is a response to critical comments concerning the inappropriate use of the potential natural vegetation (PNV) concept made in a recent contribution to the Commentary section of this journal. We consider that the PNV concept has been misinterpreted. PNV has been used extensively in several European countries since the mid‐1950s and was never intended to be used to make a prediction of what vegetation would dominate in an area if human influence were removed. PNV maps express hypothetical ...

This work documents the effect of a common, long-term fire retardant chemical, Fire-Trol 934, on seed viability and germination of 36 plant species growing in a burned Mediterranean area, covering different life-form types, regenerative strategies and distribution ranges. Seeds were subjected to four treatments: control, and application of Fire-Trol 934 at concentrations of 0.02, 0.2 and 2%. Fire-Trol 934 significantly decreased both seed viability and germination in the group of species studied, ...

Many plants from Mediterranean-type ecosystems show enhanced germination when exposed to heat and other fire-related cues. Whether Mediterranean-type plants are fire recruiters and need fire to germinate is subject of discussion. In the present work, we tested the above hypothesis by subjecting seeds from 57 species representative of a recently burned plant community to various heat pulses. Differences in germination among species, taking into account their phylogeny, were studied by dividing them ...

Farmland biodiversity is affected by factors acting at various spatial scales. However, most studies to date have focused on the field or farm scales that only account for local (alpha) diversity, and these may underestimate the contribution of other diversity components (beta diversity) to total (gamma) farmland diversity. In this work, we aimed to identify the most suitable management options and the scale at which they should be implemented to maximize benefits for diversity. We used a multi-scale ...

Abstract This paper deals with the recent debate on the potential natural vegetation ( PNV ) concept.

Mapping PNV has a descriptive aim and offers the possibility of depicting ...
