… spread through fragmentation and they are therefore suitable for artificial dispersal in the same manner. However, today there exist no technical system for dispersal of reindeer lichen. The objectives of this work was (i) to gather data and information on commercial techniques …
… tomentella has more shade tolerant properties. Dryobalanops indicated longer dispersal ability for natural regeneration than earlier studies have shown. Parashorea spp. and Shorea spp. showed short dispersal abilities for natural regeneration, a pattern in conformity with …
… explain the word biodiversity and the importance of biological diversity and dispersal in urban areas. Termsof biological dispersal are illustrated and explained together with different theories of urban dispersal.Strategies for promoting biodiversity in planning and in …
En studie av skillnaderna i odlingslandskapets konnektivitet med avseende på två skyddsvärda arter med olika preferenser
… question is posed: How is the Osmoderma eremita and the Pernis apivorus dispersal possibilities in the small scale cultivated landscape of Borås affected by exploitation in respect to a) dispersal ability, b) habitat quality, c) position of habitat patches in a network? The …
Species that have a high degree of specialization and poor dispersal ability can be more prone to extinction than more generalist species and good dispersers. How these species traits affect the viability of populations is dependent on landscape factors,such as isolation and …
… economic losses. For the pathogen to succeed with infection, spore dispersal and colonization the right environmental conditions is required. The aim of this paper is to describe the diseased stands using site and stand characteristics and to evaluate the effect of these …
… rust pustles. Rather, stem rust attacks are determined by the occurrence and dispersal of spores. The race identification was inconclusive. It appears that the gene material in the differential lines contained unknown resistance genes. Only a few races of P. graminis f. sp …
… of the species succeeded after 17 years. I aimed to study the species dispersal biology, its substrate preferences and the supply of suitable wood on this site. The study was performed during 2012 in Pansaruddens nature reserve close to Uppsala in Sweden, which is a spruce …
… of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class …
… and 39 were Scots pine. The drill cores came from five different stands with dispersal from Härjedalen to Västerbotten. The southernmost location was in Härjedalen, (latitude 61,37º) and the northernmost location, in Västerbotten, (latitude 64,52º). The drill cores were …
… number of proposals with regard to decreasing the risk for future contaminant dispersal from the landfill and to keep control of the water that is used in the area. A few of these proposals are to finally cover the landfill, to analyze the grass and plants in the enclosed …
… forest areas would increase the chances of survival for species with poor dispersal abilities. A connectivity analysis in every bvr should determine the distribution of new protection areas and bvr’s with poor connectivity should be prioritized. Improvements can be initiated …
Ett examensarbete i samarbete med NQA Nordic AB
… was made. The results from the questionnaire survey show that there is a big dispersal among the questioned organisations. Some trends are distinguishable. When it comes to communication in common it is often the information manager who communicates, when it comes to …
… threats to the tree/s- To which extent the trees have been propagated and dispersal of specimen - If applicable, to which extent the trees and classificatory clones have disappeared- Records and historical data of individual species- New data to be submitted due to the following …
ett framtida problem för områdets diversitet?
… causing major problems to the native species is termed invasive. Its natural dispersal across barriers may have been prevented but as man has turned able to rapidly travel all over the world organisms are brought to sites where they were never before observed. Adding the …
