Effects of mating system on adaptive potential for leaf morphology in Crepis tectorum (Asteraceae) 20 Aug 2013 | 07:23 pm
Background and Aims A shift from outcrossing to selfing is thought to reduce the long-term survival of populations by decreasing the genetic variation necessary for adaptation to novel ecological con...
A local dormancy cline is related to the seed maturation environment, population genetic composition and climate 20 Aug 2013 | 07:23 pm
Background and Aims Seed dormancy varies within species in response to climate, both in the long term (through ecotypes or clines) and in the short term (through the influence of the seed maturation ...
Wood anatomical correlates with theoretical conductivity and wood density across China: evolutionary evidence of the functional differentiation of axi... 20 Aug 2013 | 07:23 pm
Background and Aims In recent years considerable effort has focused on linking wood anatomy and key ecological traits. Studies analysing large databases have described how these ecological traits var...
Mutualistic ants contribute to tank-bromeliad nutrition 20 Aug 2013 | 07:23 pm
Background and Aims Epiphytism imposes physiological constraints resulting from the lack of access to the nutrient sources available to ground-rooted plants. A conspicuous adaptation in response to t...
Soybean leaf hydraulic conductance does not acclimate to growth at elevated [CO2] or temperature in growth chambers or in the field 20 Aug 2013 | 07:23 pm
Background and Aims Leaf hydraulic properties are strongly linked with transpiration and photosynthesis in many species. However, it is not known if gas exchange and hydraulics will have co-ordinated...
Community-wide assessment of pollen limitation in hummingbird-pollinated plants of a tropical montane rain forest 20 Aug 2013 | 07:23 pm
Background and Aims Although pollen limitation of reproduction (PL) has been widely studied, our understanding of its occurrence in tropical communities, especially for bird-pollinated plants, is und...
Patterns of odour emission, thermogenesis and pollinator activity in cones of an African cycad: what mechanisms apply? 20 Aug 2013 | 07:23 pm
Background and Aims Ontogenetic patterns of odour emissions and heating associated with plant reproductive structures may have profound effects on insect behaviour, and consequently on pollination. I...
Young, intact and nested retrotransposons are abundant in the onion and asparagus genomes 20 Aug 2013 | 07:23 pm
Background and Aims Although monocotyledonous plants comprise one of the two major groups of angiosperms and include >65 000 species, comprehensive genome analysis has been focused mainly on the Poac...
Medieval iconography of watermelons in Mediterranean Europe 20 Aug 2013 | 07:23 pm
Background and Aims The watermelon, Citrullus lanatus (Cucurbitaceae), is an important fruit vegetable in the warmer regions of the world. Watermelons were illustrated in Mediterranean Antiquity, but...
Population structure of Cynara cardunculus complex and the origin of the conspecific crops artichoke and cardoon 20 Aug 2013 | 07:23 pm
Background and Aims Globe artichoke and leafy cardoon, two crops within the same species Cynara cardunculus, are traditionally cultivated in the Mediterranean region and play a significant role in th...
