1. 11. Large-scale releases of native species : the mallard as a predictive model system

   Författare :Pär Söderquist; Högskolan Kristianstad; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURVETENSKAP; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Anas platyrhynchos; Farmed; Hunting; Introgression; Longevity; Mallard; Migration; Morphology; Population genetic; Restocking; SNPs; Sweden;

   Sammanfattning : Human alteration of natural systems, and its consequences are of great concern and the impact on global ecosystems is one of the biggest threats that biodiversity stands before. Translocations of invasive species, as well as intraspecific contingents with non-native genotypes, whether they are deliberate or unintentional, are one such alteration and its consequences are continuously being assessed.

3. 12. Genetic Heteroscedasticity for Domestic Animal Traits

   Författare :Majbritt Felleki; Erling Strandberg; Lars Rönnegård; Ole Fredslund Christensen; Högskolan Dalarna; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Quantitative genetics; genetic heteroscedasticity of residuals; genetic heterogeneity of environmental variation; genetic heterogeneity of residual variance; double hierarchical generalized linear models; teat count in pigs; litter size in pigs; milk yield in cows; somatic cell count in cows; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

   Sammanfattning : Animal traits differ not only in mean, but also in variation around the mean. For instance, one sire’s daughter group may be very homogeneous, while another sire’s daughters are much more heterogeneous in performance. The difference in residual variance can partially be explained by genetic differences. LÄS MER

4. 13. Women's cattle ownership in Botswana : Rebranding gender relations?

   Författare :Andrea Petitt; Seema Arora-Jonsson; Alice J. Hovorka; Cecilia Waldenström; Jaqueline Solway; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; gender; women; livestock; cattle; ownership; property; commercialization. change; intersectionality;

   Sammanfattning : Cattle are often portrayed as a male affair in Botswana. However, venturing out into the Kalahari countryside to scratch the surface of this state of affairs, another picture emerges. LÄS MER

5. 14. Evasion of CO₂ from streams : quantifying a carbon component of the aquatic conduit in the boreal landscape

   Författare :Marcus Wallin; Robert Striegl; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Lateral export of carbon (C) from soils to running waters is a persistent pathway for C with terrestrial origin. This "aquatic conduit" might be especially important in boreal regions where a significant part of the global C stock is stored in the soil. LÄS MER

7. 15. Managing coupled human and natural systems (CHANS) : the case of water

   Författare :Andreas Nicolaidis Lindqvist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Many sustainability challenges of the 21st century are the result of poor management of coupled human and natural systems (CHANS). Limited understanding of the mechanisms that give rise to complex dynamics in CHANS has contributed to overexploitation and degradation of water and other natural resources around the globe, leading to unintended consequences of well-intentioned policies.
