RCUK China-UK Programme in Global Priorities

Deadline:  30 April 2012

Research Councils UK (RCUK) and the Chinese Ministry of Science and Technology (MoST) have launched a joint call to strengthen the existing research links between the UK and China.

Funding will be provided to facilitate bilateral co-operation between British and Chinese research groups in the research areas of healthy ageing populations, energy and food security.

  • CBD Seminar:Landscape genetics of a North American songbird, the black-capped chickadee (Poecile atricapillus)
    speaker: Rachael Adams (University of Lethbridge, Alberta, Canada)

    Understanding the influence of landscapes on the spatial distribution of genetic variation in species is necessary for their successful conservation and preservation.  Physical barriers (e.g. mountains, geographic distance) often restrict population connectivity and dispersal causing a reduction in gene flow and the occurrence of genetically isolated populations.  Dispersal barriers can also be non-physical (e.g. behaviour) and occur at smaller geographic scales (e.g. changes in vegetation). 

    Although birds have high dispersal potential, evidence suggests dispersal is restricted by barriers.  One major concern lies with the increasing susceptibility of birds to changes in the environment through land use change and subsequent habitat fragmentation. 

    Assessment of the geographical area or landscape is therefore critical when measuring gene flow and making inferences about barriers, as cryptic barriers may exist.  The black-capped chickadee (Poecile atricapillus) is a common, resident songbird to North America whose range encompasses a number of dispersal barriers. 

    Here, microsatellite markers were used to assess allelic variation and population differentiation in this species, and consequently, a reduction in gene flow is evident at both large and small geographical scales.  Our sampling regime allowed us to test for breaks in the genetic structure and to determine whether the discontinuities identified correspond to changes in habitat, vegetation, physical barriers or other factors.

  • CBD Seminar: Inbreeding depression in a social context.
    speaker: Per Terje Smiseth ()

    building: Dyers Brae
    room: Seminar Room

    host/contact:

    Inbreeding depression is the reduction in fitness of offspring produced from mating of relatives. There is substantial variation in estimates of the severity of inbreeding depression, which may be caused by variation the physical and/or social environment. In this seminar, I present results from laboratory experiments on the burying beetle Nicrophorus vespilloides showing that the social environment can have a strong and sometimes surprising impact on the severity inbreeding depression.

  • Ocean circulation, nutrients, and climate
    speaker: James Rae (St Andrews)

    building: SOI
    room: LT

    host/contact:

    Ocean circulation at high latitudes exerts a first order control on nutrient concentrations, heat transport, and CO2, with impacts on regional ecosystems and global climate.  The most recent time that circulation was notably different was the last ice age and deglaciation.  At this time conditions in the Southern Ocean were more stratified and deep water formation in the North Atlantic shoaled to intermediate depths.  However the behaviour of the North Pacific under different climate regimes is a major unknown.  Based on reduced export productivity, some authors have argued for more stratified conditions.  However other records indicate that overturning circulation was enhanced.  Here we present data and model results that reconcile the nutrient and circulation data, and provide a new model for the behaviour of the Pacific during past cold climates.  More generally, we discuss the role of overturning circulation in setting nutrient regimes and climate at high latitudes, and suggest that an enhanced overturning circulation in the Pacific may have aided early human migration to North America.
