Perenniporiella chaquenia sp. nov. is described from Argentina. New records of P. pendula and P. micropora are discussed. A key to Perenniporiella species is presented. Preliminary phylogenetic relationships of Perenniporiella are inferred from parsimony and Bayesian analysis of a combined set of DNA sequence data (nuclear ribosomal partial LSU and ITS). It demonstrated that Perenniporiella forms a well resolved monophyletic clade distantly related to Perenniporia s.s. It also clearly showed that within Perenniporia as usually conceived other morphologically homogeneous group of taxa, such as the P. ochroleuca or P. vicina alliances, form well resolved clades, which could be recognized as distinct genera. The differentiation of the hyphal system and the basidiospores morphology are outlined as critical features for the definition of genera in the Perenniporia complex.

A finite element subproblem method is developed to correct the inaccuracies proper to perfect conductor and impedance boundary condition models, particularly near edges and corners of the conductors, for a large range of conductivities and frequencies. Successive local corrections, supported by fine local meshes, can be obtained from each model to a more accurate one, allowing efficient extensions of their domains of validity.

This is the first study to report on concentrations of perfluorinated organochemicals (FOCs) in marine mammals stranded along the southern North Sea coast in relation to stable nitrogen and carbon isotope ratios (delta(15)N and delta(13)C). The presence of FOCs in top predators such as marine mammals would indicate a potential biomagnification of these compounds and their widespread occurrence. Liver and kidney tissues of nine marine mammal species have been sampled. Among all the measured FOCs compounds, PFOS (perfluorooctane sulfonate) was predominant in terms of concentration. The highest PFOS concentrations were found in the liver of harbor seal compared to white-beaked dolphin, harbor porpoise, gray seal, sperm whale, white-sided dolphin, striped dolphin, fin whale, and hooded seal. PFOS concentrations differed significantly between sexes and age classes in harbor porpoises. Stable isotope measurements (delta(13)C and delta(15)N) were used in this study to describe the behavior of contaminants in food webs. We found a significant (p < 0.05) linear relationship between PFOS concentrations in livers of harbor porpoises and both Muscle delta(13)C and delta(15)N measurements. Harbor and gray seals and white-beaked dolphin, which displayed the highest trophic position, contained the highest PFOS levels, while offshore feeders such as sperm whales,fin whales, striped dolphin, and white-sided dolphin showed lower PFOS concentrations than inshore species.

Over the last decades little work has been conducted on the environmental behaviour and effects of perfluorinated organochemicals (FOCs). These chemicals are commonly used as solvents, surfactants, cosmetics and are applied in fire foam extinguishers. Recent findings have shown that FOCs (with perfluorooctane sulfonic acid - PFOS - as the most important representative) are detected in organisms living in industrialized as well as in remote areas. The fact that PFOS is hardly biodegradable, clearly accumulates in the liver and blood of top predators and the fact that little information is available on the toxic properties of PFOS, makes this chemical an environmental pollutant of primary concern. In the present study we measured PFOS concentrations in seven marine mammals stranded on the Belgian, French and Dutch North Sea coast between 1994 and 2000. PFOS concentrations were measured in liver and kidney tissue using combined liquid chromatography-mass spectrometry (LC-MS/MS). Detectable PFOS concentrations (up to 820.60 ng/g) were found in harbour porpoises, white-beaked, white-sided and striped dolphins, sperm whales and harbour seals. In fin whale and hooded seal concentrations were below the detection limit of 10 ng/g. PFOS levels in female porpoise livers were significant higher than those in males. The present results show clearly the difference in accumulation pattern of PFOS compared to that of persistent organochlorine chemicals. In order to evaluate the interspecies differences, we developed PFOS-trophic level relationships based on stable nitrogen and carbon isotope ratios. Animals that display the highest trophic positions (highest d15N) have the highest PFOS levels. The different feeding ecology of these species (inshore versus offshore) also seems to contribute to differences in PFOS concentrations. Next to the presentation of PFOS concentrations in marine mammals of the North Sea, the possible toxicological effects of perfluorinated compounds are discussed.
