Management diversification increases habitat availability for multiple biodiversity indicator species in production forests

2022

Context Forest biodiversity is closely linked to habitat heterogeneity, while forestry actions often cause habitat homogenization. Alternative approaches to even-aged management were developed to restore habitat heterogeneity at the stand level, but how their application could promote habitat diversity at landscape scale remains uncertain. Objectives We tested the potential benefit of diversifying management regimes to increase landscape-level heterogeneity. We hypothesize that different styles of forest management would create a diverse mosaic of forest habitats that would in turn benefit species with various habitat requirements. Methods Forest stands were simulated under business-as-usua…

Structure and Photocatalytic Properties of TiO2-WO3Composites Prepared by Electrophoretic Deposition

2015

In this work TiO2-WO3 composite films containing different oxide concentrations were prepared by electrophoretic deposition on steel substrates. Composite coating structures were analyzed by X -ray diffraction, Raman spectra and scanning electron microscopy. The results showed an even distribution of WO3 particles in the entire composite layer. Light absorption measurements were used for photocatalytic properties evaluation. It was found that the removal ratio of methylene blue depends on the (TiO2):(WO3) concentration ratio. The most effective photodegradation was determined for the sample that was electrophoretically deposited from the suspension with the molar content ratio n(TiO2):n(WO3…

Solving Conflicts among Conservation, Economic, and Social Objectives in Boreal Production Forest Landscapes: Fennoscandian Perspectives

2018

This chapter discusses challenges and possibilities involved in preserving biological diversity and the diversity of ecosystem services in the boreal zone and yet at the same time maintaining intensive timber extraction in boreal forests. Our focus is on Fennoscandian forests at the landscapes level, and we consider economic, social and ecological in the sustainability of forest management. We provide an outlook to boreal forest ecosystems and their history, and an overview of the forestry practices and policies that aim to ensure multi-functionality of Fennoscandian forests, i.e. diversity of efforts on sustaining biodiversity, timber production and other ecosystem services from forest lan…

COMPOSITE SYNERGY OF SERVICES - A NEW CONCEPT CONCERNING SERVICES

2013

The current paper addresses the dynamics of the service sector in Romania, from the perspective of a new concept, namely the "composite synergy of services". The main points of the paper approach the fact that direct and indirect investments in the service sector create a synergic and composite effect on the development of the economy, as a whole, in Romania. The paper aims to be a prequel to a mathematical and economic demonstration of the existence of the composite synergy of services, laying the theoretical foundations of the concept and underlining the premises for its existence.

An Easy Route Towards Regioselectively Difunctionalized Cyclens and New Cryptands.

2006

Reductive amination of various aldehydes with cyclen represents a very convenient method for the synthesis of a wide range of 1,7-difunctionalized cyclens, as well as new cryptands.

Synthesis and Structure-Affinity Relationships of Spirocyclic Benzopyrans with Exocyclic Amino Moiety

2019

σ1 and/or σ2 receptors play a crucial role in pathological conditions such as pain, neurodegenerative disorders, and cancer. A set of spirocyclic cyclohexanes with diverse O-heterocycles and amino moieties (general structure III) was prepared and pharmacologically evaluated. In structure-activity relationships studies, the σ1 receptor affinity and σ1:σ2 selectivity were correlated with the stereochemistry, the kind and substitution pattern of the O-heterocycle, and the substituents at the exocyclic amino moiety. cis-configured 2-benzopyran cis-11b bearing a methoxy group and a tertiary cyclohexylmethylamino moiety showed the highest σ1 affinity ( Ki = 1.9 nM) of this series of compounds. In…

Promotionaalisuus esikoisteosten takakansiteksteissä

2017

Tässä maisterintutkielmassa tutkin kotimaisten kaunokirjallisten esikoisteosten takakansitekstejä promotionaalisuuden näkökulmasta. Työssäni ymmärrän promotionaalisuuden laajasti kaikiksi niiksi keinoiksi, joilla pyritään herättämään potentiaalisen ostajan kiinnostus. Käytännössä tarkastelen tutkielmassani niitä kielellisiä keinoja, joita käytetään kirjan markkinoimiseksi, eli kuinka takakansitekstin lukija yritetään houkutella lukemaan koko kirja. Tutkimuskysymykset, joiden kautta aihettani tarkastelen, ovat: 1) Millainen rakenne esikoisteosten takakansiteksteissä on ja millaisista osioista ne rakentuvat? 2) Millaisilla sanavalinnoilla luodaan markkinoiville teksteille ominaista positiivis…

Genome size evolution in macroparasites.

2014

Reduction in genome size has been associated not only with a parasitic lifestyle in intracellular microparasites but also in some macroparasitic insects and nematodes. We collected the available data on genome size for flatworms, annelids, nematodes and arthropods, compared those with available data for the phylogenetically closest free-living taxa and found evidence of smaller genome sizes for parasites in six of nine comparisons. Our results suggest that despite great differences in evolutionary history and life cycles, parasitism as a lifestyle promotes convergent genome size reduction in macroparasites. We discuss factors that could be associated with small genome size in parasites whic…
