  2. 1. Effects of drought on boreal forest understory species

    Author : Irena A. Koelemeijer; Kristoffer Hylander; Johan Asplund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity conservation; boreal forests; bryophytes; canopy cover; climate change; drought; extreme climatic events; forest management; forest understory; fungi; lichens; plants; rainout shelter; soil communities; soil moisture; transplant experiment; Ecology and Evolution; ekologi och evolution;

    Abstract : Extreme climatic events, such as droughts, can have large effects on biodiversity. Drought effects in forest understories are variable over small spatial scales and can be exacerbated, or buffered, by the local vegetation structure, distance to forest edges, hydrology, and soil characteristics.

  4. 2. The hidden half of the meadow : Interactions between drought, soil carbon, roots and soil microbial communities

    Author : Daniela Guasconi; Gustaf Hugelius; Sara Cousins; Stefano Manzoni; Petra Fransson; David Johnson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; soil; soil carbon; soil ecology; roots; root traits; microbial communities; grasslands; climate change; drought; land management; compost; naturgeografi; Physical Geography;

    Abstract : Soil is a hidden ecosystem which harbours plant roots and countless microorganisms, vital for sustaining life aboveground. These belowground communities provide essential ecosystem services like soil stabilisation and organic matter decomposition. READ MORE

  5. 3. Culture and Capacity : Drought and Gender Differentiated Vulnerability of Rural Poor in Nicaragua, 1970-2010

    Author : Lisa Segnestam; Ronny Pettersson; Yvonne Svanström; Malin Beckman; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Nicaragua; Gender; Vulnerability; Adaptive capacity; Drought; Economic History; ekonomisk historia;

    Abstract : This dissertation interprets gender-differentiated vulnerability to drought within a rural community located in the dry zone, la zona seca, of Nicaragua, a region that has been identified by the government and NGO sector as suffering from prolonged and, since the 1970s, more frequent droughts.  A combination of gender, capitals, and vulnerability demonstrates the value in using a multidimensional perspective to look at the socioeconomic and cultural contexts that form the capacity individuals have had to reduce their long-term vulnerability to drought in Nicaragua.
