2. 21. Behavioural differences and genetic relationships between four captive populations of red junglefowl (Gallus gallus) : possible implications for conservation

   Author : Jennie Håkansson; Linköpings universitet; []
   Keywords : Red junglefowl; behavioural differences; genetic relationships; captive populations; NATURAL SCIENCES; NATURVETENSKAP;

   Abstract : Conservation of species is to a large extent carried out by zoos where animals are kept in small populations under protected conditions. The ultimate goal of such ex situ conservation programs is to eventually reintroduce the animals into natural habitats to provide support for the survival of the species. READ MORE

4. 22. Spatial Strategies for Biodiversity Conservation

   Author : André Pinto da Silva; Mats Bjõrklund; Greta Bocedi; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; global change; Southern Asia; mammals; ecological modelling; Biology with specialization in Animal Conservation; Biologi med inriktning mot zoologisk bevarandebiologi;

   Abstract : Biodiversity is being lost under alarming rates due to an unsustainable socio-economic trajectory causing global change. Such loss is unequally spread over the Earth, and Southern Asia has been and is projected to continue to be one of the most affected regions. READ MORE

5. 23. The use of museum specimens in conservation genomics

   Author : Johanna von Seth; Love Dalén; Karin Norén; Gernot Segelbacher; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; conservation genomics; museum specimens; genomic erosion; diversity; inbreeding; mutational load; genetic drift; purging; population divergence; local extinction; population decline; Sumatran rhinoceros; kakapo; arctic fox; Chatham Island black robin; Systematic Zoology; zoologisk systematik och evolutionsforskning;

   Abstract : In the face of an increasing number of species being threatened by extinction, museum collections can constitute a powerful resource for acquiring genomic data of endangered taxa. By utilising datasets that combine genomes from present-day populations with those from historical timepoints, several questions relevant for conservation can be investigated. READ MORE

6. 24. Uncertainty Quantification and Numerical Methods for Conservation Laws

   Author : Per Pettersson; Jan Nordström; Gianluca Iaccarino; Gunilla Kreiss; Rémi Abgrall; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; uncertainty quantification; polynomial chaos; stochastic Galerkin methods; conservation laws; hyperbolic problems; finite difference methods; finite volume methods; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

   Abstract : Conservation laws with uncertain initial and boundary conditions are approximated using a generalized polynomial chaos expansion approach where the solution is represented as a generalized Fourier series of stochastic basis functions, e.g. orthogonal polynomials or wavelets.

7. 25. Decision making on indoor climate control in historic buildings : knowledge, uncertainty and the science-practice gap

   Author : Gustaf Leijonhufvud; Tor Broström; Simon Stefan; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; Preventive conservation Environmental control; Energy efficiency; Decision-making; Knowledge sharing; Preventive conservation; Environmental control; Energy efficiency; Decision-making; Knowledge sharing;

   Abstract : Balancing use, preservation and energy use is a fundamental challenge for the whole heritage field. This is put to the point in designing and operating systems for indoor climate control in historic buildings, where competing objectives such as preservation, comfort, accessibility, energy use and cost have to be negotiated in the individual case.
