1	Bumblebee (Bombus spp.) occurrence in relation to vegetation height, variation in vegetation height and flower abundance Islamovic, Azra January 2014 (has links) Bumblebees are a group of valuable pollinators that are declining all over the world. The main reason is believed to be habitat loss due to the changes in agriculture. The changes in agriculture influence the structure of the vegetation and flower abundance, which are of great importance to the abundance of bumblebees. The aims of this study were to get a better understanding of bumblebees and what preferences they might have regarding vegetation height and flower abundance in semi-natural grasslands. This study is based on data collected by a Swedish national environmental monitoring program in 2006-2010. Data on twelve bumblebee species were analysed using a generalized linear model based on the dependent variables of occurrence/ non-occurrence. The target variables used in the analysis were flower abundance, vegetation height and standard deviation of vegetation height. The species-wise analyses mostly showed no or weak positive relationships between the bumblebee occurrence and the three target variables. Grouping the species-wise results into ecologically meaningful guilds and analysing them did not increase the explanatory power of flower abundance or vegetation characteristic, but vegetation height showed significant (positive) results in relation for the forest dwelling species and the species group non-parasite and parasite. The results of this study were considerably weaker than expected. Flower abundance and variation in vegetation height could not explain the occurrence of bumblebees. However, the results of this study show that vegetation height is of importance to the occurrence of bumblebees. Bumblebees in general seem to prefer a higher vegetation height. Based on the findings of this study I would recommend a low intensity of grazing in semi-natural grasslands. Grazing management recommendations nectar pollinator seminatural grassland Sweden
2	Kertinių miško buveinių būklės pokyčiai Šiaulių miškų urėdijoje / Changes of woodland's habitats condition of Siauliai forestry enterprise Nemunis, Gintaras 21 June 2012 (has links) Magistro darbe tiriami Šiaulių miškų urėdijos kertinių miško buveinių būklės pokyčiai 2004 – 2011 m. Darbo objektas – Šiaulių miškų urėdijos kertinės miško buveinės. Darbo tikslas – nustatyti KMB būklės pokyčius ir pateikti jų apsaugos ir tvarkymo rekomendacijas VĮ Šiaulių miškų urėdijos miškuose. Darbo metodai – literatūros loginė analizė, inventorizacijos duomenų analizė, palyginimas ir vertinimas. Darbo rezultatai. Šiaulių miškų udėdijos kertinėse miško buveinėse nustatytas ryškus spacializuotųjų ir indikatorinių rūšių pokytis: specializuotųjų kerpių ir indikatorinių samanų rūšių aptikimo atvejų padaugėjo – atitinkamai 20,0 ir 10,6 proc., tačiau ženkliai sumažėjo specializuotųjų grybų (43,1 proc.), indikatorinių induočių (44,4 proc.), moliuskų (50,0 proc.) ir vabalų rūšių (50,0 proc.) aptikimo atvejų. Šiaulių miškų urėdijos (P)KMB skaičius ir plotas 2011 m., palyginti su 2004 m., išliko beveik nepakitęs. Labiausiai sumažėjo medžių milžinų grupių (P)KMB tipas (20 vnt.). Kertinių kraštovaizdžio (33,1 proc.) ir biologinių elementų pokytis (71,4 proc.) buvo teigiamas. Šiaulių miškų urėdijoje 27,2 proc. (P) KMB siūloma nevykdyti jokių ūkinių priemonių. Kitais atvejais siūloma šviesinti apie pavienius medžius (224 kartai), kirsti pomiškį (28 kartai), kirsti traką (25 kartai), nešalinti medienos ir sausuolių (11 kartų), taikyti apsaugos zoną (4 kartai), išsaugoti stambius lizdus (2 kartai). / The master thesis analyses the changes of woodland's habitats condition of Siauliai Forestry Enterprise during the period of 2004–2011. The object of master thesis – woodland's habitats. The aim of master thesis – to ascertain the changes of woodland's habitats condition and give the recommendations of their protection and management in the forests of Siauliai State Forestry Enterprise. The methods of master thesis – logical analysis of literature, inventory data analysis, comparison and evaluation. The results of master thesis. The conspicuous change in specialized and indicator species of Siauliai Forestry Enterprise woodland's habitats has been ascertained. Despite the fact that the cases of specialized lichens and indicator moss have increased respectively 20.0 percent and 10.6 percent, there has been determined a significant decrease in detection of cases of specialized fungus (43.1 percent), vascular indicator plants (44.4 percent), mollusks (50.0 percent) and beetle species (50.0 percent). The number and the area of Siauliai Forestry Enterprise potential woodland's habitats, comparing 2011 year and 2004 year, have remained practically stable (decreased by one woodland habitat or 0.7 ha). Mostly decreased the type of potential woodland's habitat of giant trees groups (20 units) in Siauliai Forestry Enterprise. The change in woodlands' landscape (33.1 percent) and biological elements (71.4 percent) were positive. 27.2 percent of woodland's habitats in Siauliai Forestry...
