1. 1. Effects of seed size and habitat on recruitment patterns in grassland and forest plants

   Författare :Karin Lönnberg; Ove Eriksson; Per Milberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seed size; seedling establishment; seedling survival; recruitment; seed removal; co-existence; game-theory; Plant Ecology; växtekologi;

   Sammanfattning : A trade-off between seed size and seed number is central in seed ecology, and has been suggested to be related to a trade-off between competition and colonization, as well as to a trade-off between stress tolerance and fecundity. Large seeds endure hazards during establishment, such as shading, drought, litter coverage and competition from other plants, better than do small seeds, due to a larger amount of stored resources in the seed.

3. 2. Natural and Sexual Selection in a Natural Hybrid Zone of Ficedula Flycatchers

   Författare :Nina Svedin; Anna Qvarnström; Lars Gustafsson; Ian Owens; Uppsala universitet; []
   Nyckelord :Biology; postzygotic isolation; prezygotic isolation; asymmetrical isolation; sexual signals; hybrid fitness; co-existence; Biologi;

   Sammanfattning : Speciation can be viewed as the formation of reproductive barriers between different populations. This thesis investigates patterns of natural and sexual selection shaping reproductive barriers between two hybridizing flycatchers (i.e. collared – and pied flycatchers). LÄS MER

4. 3. How the sensory ecology of the bumblebee affects their functional traits

   Författare :Vun Wen Jie; Emily Baird; Mikael Carlsson; Martin How; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bumblebee; functional morphological traits; intraspecific differences; allometry; DRA; micro-CT; co-existence; Functional Zoomorphology; funktionell zoomorfologi;

   Sammanfattning : Morphological traits are important for trait-based ecological studies as they allow for the prediction of biodiversity across the biosphere. Currently, the predictive power of trait-based ecology is not often applied to terrestrial arthropods, even though they provide us with important agricultural, ecological, and cultural value.

5. 4. The challenge of co-existence : from graft-versus-host disease to stable mixed chimerism after allogeneic hematopoietic stem cell transplantation

   Författare :Arwen Stikvoort; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The only curative treatment strategy for many hematologic and inborn immunodeficiency disorders is an allogeneic hematopoietic stem cell transplantation (HSCT). The treatment involves replacing the entire hematopoietic system of the recipient. LÄS MER

7. 5. Kungamakt och bonderätt : om danska kungar och bönder i riket och i Göinge härad ca 1525-1640

   Författare :Stefan Persson; Historia; []
   Nyckelord :HUMANIORA; HUMANITIES; De-centralised structure; Inter-dependence; Topography; Border region; Border defences; Identity; Militarisation; Centralisation; Social discipline; Historia; Politisk historia; Political history; Interaction; History;

   Sammanfattning : In the early-modern period, Danish peasants living on crown estates across the country found a profitable way of interacting with the crown and its representatives. The necessary co-existence of rulers and ruled was marked by inter-dependence, solidarity of interest, and inter-subjective resolution of conflict. LÄS MER
