2. 1. 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

4. 2. 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.

5. 3. Stelar Performance Under Drought : Regulation of Developmental Robustness and Plasticity of the Arabidopsis Root Xylem

   Author : Prashanth Ramachandran; Annelie Carlsbecker; Ari Pekka Mähönen; Uppsala universitet; []
   Keywords : HD-ZIP III TFs; miR165; Xylem; ABA; VND; plasticity; water deficit; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

   Abstract : Plants have evolved genetic mechanisms to sense, modulate and modify developmental programs in response to the changing environment. This brings forth challenges in stably generating tissue patterns while simultaneously allowing amenability. READ MORE

6. 4. Water level management of wetlands in response to current and future RCP climate change scenarios : A mesocosm experiment within climate control chambers

   Author : Shokoufeh Salimi; Avdelningen för Teknisk vattenresurslära; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; peatland; constructed wetland; water quality; carbon dioxide emission; ; drought; nutrient release;

   Abstract : Wetlands are integral components of our natural environment since they provide many critical ecosystem services to humanity, such as water purification, climate change mitigation, flood control, and biodiversity. Although wetlands can convey resilience to some degree of changes, they might be vulnerable to climate change. READ MORE

7. 5. Soil microbial diversity in agriculture : Responses to land-use and extreme weather events

   Author : Katja Kozjek; Biodiversitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; agriculture; drought; soil microbial communities; taxonomic diversity; functional diversity;

   Abstract : Land-use intensification of agricultural soils and increased occurrence and intensity of extreme weather events like drought periods are two of the main threats responsible for soil biodiversity declines. These changes in soil biodiversity can alter ecosystem functions performed especially by soil microbial communities that could further contribute to those threats. READ MORE
