1. 1. Temperature and the synchrony of plant-insect interactions

   Författare :Tenna Toftegaard; Johan Ehrlén; Karl Gotthard; Christer Wiklund; Annette Menzel; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Brassicaceae; Anthocharis cardamines; climate change; development; oviposition; phenology; species interactions; herbivory; synchrony; timing; phenotypic plasticity; local adaptation; Plant Ecology; växtekologi;

   Sammanfattning : Increasing temperatures resulting from climate change have within recent years been shown to advance phenological events in a large number of species worldwide. Species can differ in their response to increasing temperatures, and understanding the mechanisms that determine the response is therefore of great importance in order to understand and predict how a warming climate can influence both individual species, but also their interactions with each other and the environment.

3. 2. Population and Community Dynamics in Variable Environments

   Författare :Jörgen Ripa; Evolutionär ekologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dispersal; Moran effect; linear dynamics; synchrony; power spectrum; autocorrelation; extinction risk; population dynamics; environmental stochasticity; migration; stochastic modelling; Ecology; Ekologi;

   Sammanfattning : All natural populations fluctuate in space and time. These fluctuations are a result of internal dynamic processes, and of a variable environment. LÄS MER

4. 3. La formation agentive en français : les composés [VN/A/Adv/P]N/A et les dérivés V-ant, V-eur et V-oir(e)

   Författare :Maria Rosenberg; Olof Eriksson; Mats Forsgren; Georgette Dal; Bernard Fradin; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; agentive formations; agent nouns; compounds; contrastive; derivations; diachrony; French; instrument; lexeme; morphology; polysemy of agent; productivity; semantic patterns; semantics; Swedish; synchrony; VN compounds; verb stem; word formation; French language; Franska språket; French; franska;

   Sammanfattning : This study addresses the French morphological construction [VN/A/Adv/P]N/A. The main objectives are to posit a single rule for its formation and to question the implications of the agent polysemy. The theoretical framework is lexeme-based morphology, which adheres to weak lexicalism. LÄS MER

5. 4. Potential impact of climate change on European agriculture: a case study of potato and Colorado potato beetle

   Författare :Bakhtiyor Pulatov; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Colorado potato beetle; climate change; day length; degree day model; frost damage; distribution; temperature; potato; regional climate model; synchrony;

   Sammanfattning : European agriculture is facing the challenge of managing the impact of climate change on food security. Agriculture in a northern temperate climate is likely to benefit from higher temperature and longer growing season while, in the south, crop productivity is likely to decline. LÄS MER

7. 5. Swedish Numerals in an International Perspective

   Författare :Magnus Olsson; tolkning i offentlig sektor och översättning danska och isländska Avdelningen för svenska; []
   Nyckelord :HUMANIORA; HUMANITIES; synchrony; round numbers; base; vacillation; parallelism; affinity; inflection; derivation; dualism; affix; language change; language planning; dates; number; measurement; typology; homonymy; semantics; syntax; phonology; morphology; designation transition; Scandinavian languages and literature; Nordiska språk språk och litteratur ;

   Sammanfattning : Swedish numerals are here treated from different points of view. The book is however not intended to be a textbook of Swedish numerals, though one may learn a great deal about the system herein - more than the general user of the language knows. Phonology, morphology, syntax and semantics all get their fair share of attention. LÄS MER
