The Ecophysiology of Arbuscular Mycorrhizal Fungi: Phosphatase Activity Associated with Extraradical and Intraradical Mycelium

Popular Abstract in Swedish Svampmycel i marken hämtar sin energi både från levande och dött organiskt material. Vissa svampar hämtar energi direkt från levande växter genom att bilda en symbios som kallas mykorrhiza. Arbuskulär mykorrhiza (AM) är en sådan typ som bildas av svampar som inte kan leva utan värdväxter. AM-svamp hämtar sin energi från rötter, samtidigt tar svampen upp viktiga växtnäriArbuscular mycorrhizal (AM) fungi colonise a wide range of plant species and are especially common in soils with a relatively high pH, where phosphorus availability is a limiting factor for primary production. The aim of this thesis was to study the ecophysiology of arbuscular mycorrhizal (AM) fungi when exposed to different environments. Development of AM fungi and their host plants were investig

Institutional Fragmentation

the body of literature on institutional fragmentation and interlinkages has become quite extensive over the last 10-15 years, especially in global environmental governance research. This common ground and the merits of existing scholarly approaches notwithstanding, there are still major new conceptual, theoretical and empirical grounds to be explored. Conceptually, the literature could further go

Invading Herbivory. Effects of the Golden Apple Snail (Pomacea canaliculata) in Asian Wetlands.

Popular Abstract in Swedish Populärvetenskaplig sammanfattning av avhandlingen "Invading Herbivory. Effects of the Golden Apple Snail (Pomacea canaliculata) in Asian wetlands". 1980 förde några affärsmän ett okänt antal individer av den sydamerikanska vattensnäckan Pomacea canaliculata till Taiwan. Snäckorna skulle odlas i dammar och säljas som människoföda på marknader i Asien och överskottet skThe South American golden apple snail (Pomacea canaliculata) was intentionally introduced to aquacultures in South East Asia to produce snails for human consumption, but the aquatic snails soon escaped and started to consume large amounts of rice seedlings. The aim of this thesis was to quantify the effects of this invasive herbivore on aquatic plants in natural wetlands since previous research h
