AIM: To determine the clinical reasons for conversion to everolimus(EVL) and long-term outcomes in heart transplant(HT) ***: A retrospective 12-mo study has been carried out in 14 Spanish centres to assess the efficacy and safety of conversion to EVL in maintenance HT ***: Two hundred and twenty-two patients were included(mean age: 53 ± 10.5 years; mean time from HT: 8.1 ± 4.5 years). The most common reasons for conversion were nephrotoxicity(30%), chronic allograft vasculopathy(20%) and neoplasms(17%). The doses and mean levels of EVL at baseline(conversion to EVL) and after one year were 1.3 ± 0.3 and 1.2 ± 0.6 mg/d and 6.4 ± 3.4 and 5.6 ± 2.5 ng/mL, respectively. The percentage of patients receiving calcineurin inhibitors(CNIs) at baseline and on the final visit was 95% and 65%, respectively. The doses and mean levels of CNIs decreased between baseline and month 12 from 142.2 ± 51.6 to 98.0 ± 39.4 mg/d(P from 126.1 ± 50.9 to 89.2 ± 47.7 ng/mL(P for cyclosporine, and from 2.9 ± 1.8 to 2.6 ± 1.9 mg/d and from 8.3 ± 4.0 to 6.5 ± 2.7 ng/mL(P = 0.011) for tacrolimus. In the subgroup of patients converted because of nephrotoxicity, creatinine clearance increased from 34.9 ± 10.1 to 40.4 ± 14.4 mL/min(P f acute rejection in 24 patients(11%). The most frequent adverse events were oedemas(12%), infections(9%) and gastrointestinal problems(6%). EVL was suspended in 44 patients(20%). Since the database was closed at the end of the study, no further followup data is ***: Conversion to EVL in maintenance HT recipients allowed minimisation or suspension of the CNIs, with improved kidney function in the patients with nephrotoxicity, after 12 mo.

High philopatry rates of Yellow-legged Gulls in the southeastern part of the Bay of Biscay

Background:Philopatry rate is one of the main factors shaping population dynamics in colonial *** rates of philopatry are linked to populations with high dispersal,while high rates are linked to populations with a very high spatial structure pattern(i.e.,metapopulations).The Cantabrian Yellow-legged Gull(Larus michahellis)population is considered to be resident,with relatively low dispersal *** estimations of its philopatry rates are however still ***,we aimed to estimate philopatry rates in the main Yellow-legged Gull colonies of the province of Gipuzkoa,in the southeastern part of the Bay of ***:We analysed 734 resightings,during the breeding season at the colonies of Getaria,Santa Clara and Ulia,relative to a total of 3245 individuals ringed at birth in these same colonies during a period of 13 *** data were analysed using Multi-State Recapture models in ***:After controlling survival and resighting probability,the average dispersal rate among colonies was 4%(±SD=2%)when individuals are immature,decreasing to 1±1%)for adult breeding gulls(i.e.,philopatry rate was 99%).Annual survival rates were assessed to be 0.27±0.02 for birds in their first year of life and 0.87±0.01 for older *** probability of observing immature birds in the colonies was 0.08±0.01,as compared to 0.21±0.02 in adult ***:We obtained evidence of extremely high local philopatry rates,clearly within the upper limit found in gulls.A high philopatry favour a speciation in these species who are vulnerable to obtain the main food source(land-fills and fishing discard)which are transforming under new ecological process.

Macrofaunal communities of threatened subtidal maёrl seabeds on Tenerife (Canary Islands, north-east Atlantic Ocean) in summer

Acta Oceanologica Sinica 2012年第1期31卷 98-105页

作者： Rodrigo Riera juan Domingo delgado Myriam Rodríguez Óscar Monterroso Eva Ramos Centro de Investigaciones Medioambientales del Atlántico(CIMA SL) C/Arzobispo Elías Yanes Área de Ecología Departamento de Sistemas FísicosQuímicos y Naturales.Facultad de Ciencias ExperimentalesUniversidad Pablo de Olavide

This study contributes with the first data on physical and taxonomical structure of macrofaunal assemblages of maerl beds from the Canary Islands. Maerl beds and Cymodocea nodosa meadows of the Canary Islands are considered biodiversity hot-spots in terms of taxonomic and functional biodiversity with a broad geographical and depth ranges. The authors have studied the structure of the macrofaunal assemblages on different habitat types （Cymodocea, Caulerpa, sabellid field, garden eel and maerl beds）. Samples were taken at a range of depths between 14 and 46 m. Correlations were performed among abiotic variables （granulometry, organic matter, nitrogen and phosphates） and the most abundant taxa. Similarity analysis was performed to explore the patchiness of seabeds at a local scale. Significant differences were found in macrofaunal assemblages among seabed types, with highest abundances and lowest biodiversity in sabellid fields, where the sabellid Bispira viola dominated. The polychaetes Aponuphis bilineata and Chone filicauda and the mollusc Turritella brochii were the most abundant taxa on maerl beds. The mosaic of granulometric conditions would explain the associated macroinfaunal community structure and contribute to the creation of diversity on these relatively well preserved seabeds at a local scale.

Dissolved Organic Nitrogen in Mediterranean Ecosystems

引用

Pedosphere 2011年第3期21卷 309-318页

作者： M.delgado-BAQUERIZO f.COVELO A.GALLARDO Department of Physical Chemical and Natural Systems University Pablo de Olavide Ctra. de Utrera km.1Seville 41013 (Spain)

Dissolved organic nitrogen （DON） in soils has recently gained increasing interest because it may be both a direct N source for plants and the dominant available N form in nutrient-poor soils, however, its prevalence in Mediterranean ecosystems remains unclear. The aims of this study were to i） estimate soil DON in a wide set of Mediterranean ecosystems and compare this levels with those for other ecosystems; ii） describe temporal changes in DON and dissolved inorganic nitrogen （DIN） forms （NH＋ and NO3）, and characterize spatial heterogeneity within plant communities; and iii） study the relative proportion of soil DON and DIN forms as a test of Schimel and Bennett＇s hypothesis that the prevalence of different N forms follows a gradient of nutrient availability. The study was carried out in eleven plant communities chosen to represent a wide spectrum of Mediterranean vegetation types, ranging from early to late successional status. DON concentrations in the studied Mediterranean plant communities （0-18.2 mg N kg-1） were consistently lower than those found in the literature for other ecosystems. We found high temporal and spatial variability in soil DON for all plant communities. As predicted by the Schimel and Bennett model for nutrient-poor ecosystems, DON dominance over ammonium and nitrate was observed for most plant communities in winter and spring soil samples. However, mineral-N dominated over DON in summer and autumn. Thus, soil water content may have an important effect on DON versus mineral N dominance in Mediterranean ecosystems

Particulate matter （PM） emissions from various sources can affect significantly human health and environmental quality especially in the Chihuahuan Desert region along US- Mexico border. The objective of this study was to use the low-cost sticky tape method to collect airborne PM for size characterization and identification of fungal spores. Sticky tape samplers were placed at 1.0 and 2.0 m above the ground surface at experimental sites in Ciudad Ju＆ez, Mexico and at 0.6, 1.2 and 1.8 m at New Mexico sites, USA. Soil samples were collected in both countries to determine fungal diversity, texture and moisture content. Dust particles collected from all of the experimental sites had a dominant texture of clay （〈0.002 mm）. The dominant textures identified from soil samples collected from the US and Mexican sites were loam and sandy clay loam, respectively. Alternaria, Penicillium and fusarium were frequently found funguses in the US sites while Alternaria and Aspergillus were commonly observed in the Mexican sites. The sticky tapes also showed a similar diversity of fungal microorganisms present in the airborne PM at both Mexico and US sites. Alternaria, Penicillium and Aspergillus were the three groups of airborne fungal microorgan- isms consistently present in the US and Mexican sites. The low-cost sticky tape method has the potential to be used for characterizing different airbome microorganisms and dust particles.
