1. Swedish seagrass ecosystems in a changing climate : Coastal connectivity and global change sensitivity
Abstract : Coastal shallow-water ecosystems are essential for providing several goods and services globally, with seagrasses as an important contributor for maintaining high biodiversity and productivity within the nearshore seascape. The temperate species Zostera marina serves as a vital habitat for many species, including ecologically and economically important juvenile fish. READ MORE

2. Seagrasses in warming oceans : physiological and biogeochemical responses
Abstract : The exponential increase of atmospheric greenhouse gas concentrations over the past 50 years has caused a rise in the global average temperature by more than 1ºC above pre-industrial levels. Ninety-three percent of this heat energy has been absorbed and stored by the oceans, increasing their temperatures, particularly in surface waters. READ MORE

A developmental switch determines whether a temperate phage will grow lytically or form lysogeny after infection. P2 related phages have two face-to-face located promoters controlling the lysogenic and the lytic operon respectively, and two repressors. READ MORE

Considering the present small area of the forest type, the habitat is of considerable interest for biodiversity, and knowledge about the history of temperate broadleaves is crucial for forest conservation and management.

5. Old-Growth Forests in the High Coast Region in Sweden and Active Management in Forest Set-Asides
Abstract : In today´s intensively managed landscape, very few forests with old-growth characteristics and little human impact exist. One of the rare exceptions is pine forests on rocky soils, a forest type which has probably escaped extensive human use because of its low productivity. READ MORE
