Agroforestry systems, where productive trees are integrated into agricultural land, can deliver benefits to biodiversity, natural pest control, and pollination, but the effects highly variable. Recent advances in our understanding of flower strips systems suggest that management tree row understorey could be an important contributor this variation. Here, we compare two cutting regimes for under...
In forests where the overstorey canopy has been disturbed by timber harvest or other means, evapotranspiration (ET) understorey may be main flux of water back to atmosphere. However, little research apportioned directly measuring use, and technology do so is thus limited. Here, we used a portable chamber quickly measure ET from soil vegetation enclosed chamber. This method was in third-growth c...
Ground-ivy ( Glechoma hederacea L.) is a widespread stoloniferous plant that grows in several ecologically diverse habitats: the open, at forest edge, and understorey. The vegetation of ground-ivy habitats was studied NE Slovenia terms floristic richness diversity, biological spectrum, phytogeography syntaxonomy. We identified five clusters distinct with occurrence ground-ivy, differentiated ac...
1 Field and laboratory experiments on the conservation biocontrol of lepidopteran leafroller pests were carried out in apples at Lincoln, New Zealand. 2 Apple understoreys were planted with replicated treatments of alyssum (Lobularia maritima), phacelia (Phacelia tanacetifolia) and buckwheat (Fagopyrum esculentum). 3 Rates of parasitism of experimentally released larvae of the light-brown apple...
The germination response of Ocotea pulchella (Nees) Mez seeds to light, temperature, water level and pulp presence is introduced. The laboratory assays were carried out in germination chambers and thermal-gradient apparatus, whereas the field assays were performed in environments with distinct light, temperature and soil moisture conditions within a permanent parcel of Restinga forest of the Pa...
Using molecular fingerprinting (amplified fragment length polymorphism [AFLP] method), we explored the potential of small-scale population analysis for understanding colonization patterns of herb layer species in forests after canopy disturbance. We investigated three common forest understorey species with different life forms (Trientalis europaea, Calamagrostis villosa, and Vaccinium myrtillus...
