The success of crayfish stocking in a dredged river with and without artificial shelter increase

1997

Abstract The success of crayfish ( Astacus astacus L.) stocking in a heavily dredged river in Finland was compared between sections with and without artificial shelter. The materials used for creating shelter were a) broken rock and, b) ceramic drain pipes and perforated bricks. Group-marked crayfish (mean carapace length 42.6 mm) were released into the sections and test trappings conducted one year later. The highest crayfish densities were found in the broken rock sections. The reasons for the observed crayfish densities are discussed. No significant differences in growth between groups were detected. Migrations in the range of 2.5 km in one year were recorded.

Vertical preparation for fixed prosthesis rehabilitation in the anterior sector

2015

This clinical report describes a biologically oriented preparation technique (BOPT) for teeth and an implant for the esthetic rehabilitation of the maxillary anterior sector. The technique was designed to create an anatomic crown with a prosthetic emergence profile that simulated the shape of the natural tooth.

The contribution of forest restoration to the conservation of woody endangered species in Sicily

2017

Sicilian forest ecosystems are, in general, numerically poor in terms of their floristic composition. As many studies on Sicilian dendroflora have highlighted, such poorness is not intrinsic to forest formations, but it is due to the millenary human pressures. Repeated passage of fire, continuous wood usage and reforestations by single or few species dra- matically reduced the plant biodiversity of Sicilian forest ecosystems, often suffering of monodominance. The Sicilian dendroflora includes several endangered species, such as Abies nebrodensis, Betula aetnensis, Celtis tournefortii subsp. asperrima and subsp. aetnensis, as the wild pears, which in Sicily are represented by 4 endemic speci…

Plant-frugivore networks are less specialized and more robust at forest-farmland edges than in the interior of a tropical forest

2012

Forest fragmentation and local disturbance are prevailing threats to tropical forest ecosystems and affect frugivore communities and animal seed dispersal in different ways. However, very little is known about the effects of anthropogenic forest edges and of local disturbance on the structure and robustness of plant–frugivore networks. We carried out focal tree observations to record the frugivore species feeding on eight canopy tree species in the forest interior and at forest–farmland edges in a little and a highly disturbed part of a Kenyan rain forest. For each frugivore species, we recorded its body mass and its forest dependence. We examined how forest edge and local disturbance affec…

Past and Contemporary Changes in Forest Cover and Forest Continuity in Relation to Soils (Southern Latvia)

2014

A set of medium-scale historical maps was used to reconstruct changes in spatial patterns of forest area during the last 220 years in an agricultural matrix of northeastern Europe (Zemgale region, Latvia). Changes in total forest area by soils were determined, as well as the time period of continuous forest cover. Proportion of protected area for each soil trophic group was also calculated. Patterns of recent forest development differed between soil trophic groups. Afforestation occurred mainly on wet and poor soils in the 19th and 20th centuries, while the proportion of woodland area on fertile soils typical for nemoral forests was fairly stable. Only 1% of the fertile soil area has been c…

Effect of commercial mineral-based additives on composting and compost quality.

2009

Abstract The effectiveness of two commercial additives meant to improve the composting process was studied in a laboratory-scale experiment. Improver A (sulphates and oxides of iron, magnesium, manganese, and zinc mixed with clay) and B (mixture of calcium hydroxide, peroxide, and oxide) were added to source-separated biowaste:peat mixture (1:1, v/v) in proportions recommended by the producers. The composting process ( T , emissions of CO 2 , NH 3 , and CH 4 ) and the quality of the compost (pH, conductivity, C/N ratio, water-soluble NH 4 –N and NO 3 –N, water- and NaOH-soluble low-weight carboxylic acids, nutrients, heavy metals and phytotoxicity to Lepidium sarivum ) were monitored during…

MIRADA RESTAURATIVA DE LA JUSTICIA PENAL EN ESPAÑA, UNA BOCANADA DE AIRE EN LA SOCIEDAD GLOBAL LÍQUIDA DEL MIEDO Y DE LA SECURITIZACIÓN (A Restorativ…

2019

English Abstract: La evolucion historica de la Justicia Penal, fruto de la integracion de elementos poliedricos, heterogeneos y fusionados, que incidiendo en ambitos como la sociedad, la cultura, la economia, la demografia, la politica y un largo etcetera, tambien han alcanzado al mundo del derecho y por supuesto a los fundamentos y a la construccion de la idea de Justicia y a los postulados de la Justicia Penal en particular, permite la comprension del papel que en la actualidad, en el mundo globalizado que vivimos, asume la Justicia Penal. E igualmente facilita el entendimiento de las coordenadas que le son propias; unas coordenadas que se asientan en la vision economicista palmaria, en l…

A New Look at the Stochastic Linearization Technique for Hyperbolic Tangent Oscillator

1998

Abstract Stochastic linearization technique is reconsidered for oscillator with restoring force in form of hyperbolic tangent. We show that a subtle error was made in the previously known procedure for derivation of the linearized system parameters. Two new error-free procedures, namely, those based on minimization of mean square difference between (a) restoring force or (b) potential energy of the original non-linear system and their linear counterparts, are suggested. The results of numerical analysis are shown.

Recolonization after habitat restoration leads to decreased genetic variation in populations of a terrestrial orchid.

2012

Colonization is crucial to habitat restoration projects that rely on the spontaneous regeneration of the original vegetation. However, as a previously declining plant species spreads again, the likelihood of founder effects increases through recurrent population founding and associated serial bottlenecks. We related Amplified Fragment Length Polymorphism markers genetic variation and fitness to colonization history for all extant populations of the outcrossing terrestrial orchid Dactylorhiza incarnata in an isolated coastal dune complex. Around 1970, D. incarnata suffered a severe bottleneck yet ultimately persisted and gradually spread throughout the spatially segregated dune slacks, aided…
