1. Trädgårdsmästarens förökningsmetoder – schema och katalog över förökningsdelar vid vegetativ förökning av fleråriga örtartade växter
Sammanfattning : The purpose of this licentiate thesis is to gather and classify information about traditional vegetative propagation of perennial herbaceous plants. This thesis is the first, self-contained part of a survey of propagation methods used by horticulturists. LÄS MER
2. Smallholder farm management and priorities : balancing productivity, livelihood, climate adaptation and ecosystem services
Sammanfattning : Smallholders in sub-Saharan Africa are highly vulnerable to climate change, but also have good potential for improving production. This thesis examined how Kenyan smallholders manage their farming systems to adapt to rainfall variability and improve productivity, while also maintaining sustainable delivery of multiple ecosystem services.

5. Large-scale releases of native species : the mallard as a predictive model system
Sammanfattning : Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed.
