1. 1. The common meadow EuropeanGrasshopper (Chorthippus parallelus)as a window to the process ofspecies formation

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Enrique Celemín Amaro; [2020]
   Keywords : Speciation genomics; Phylogeography; Species tree; Incomplete Lineage Sorting ILS ; Gene tree discordance; Postglacial expansion; Secondary contact;

   Abstract : Despite more than 50 years of research on the genetic basis of speciation, we still know very little about the early stages of this process. A general rule of speciation is the Haldane’s Rule, which states that postzygotic isolation is expressed earlier in the heterogametic sex: sterility and inviability in hybrids is much more likely to occur in the heterogametic sex.

3. 2. Perceptions and relation-mediating mechanisms in human-wildlife conflicts : in the context of the reintroduction of the brown bear in the Pyrenees (France)

   University essay from SLU/Dept. of Urban and Rural Development

   Author : Arthur Le Comte Du Colombier; [2019]
   Keywords : perception; brown bear; Pyrenees; historical background; psychological ownership; identification practice; Disneyfication; social representation; human-wildlife conflict;

   Abstract : Human-wildlife conflict represents a recurring challenge in the history of humankind. Since the 1970s and the environmental awakening of consciousnesses, the problem took a new dimension through competitions between people with different views about nature and wildlife. READ MORE

4. 3. Studying the feasibility of installing a temperature independent snowmaking system with heat recovery : Case study for the ski resort of Astún

   University essay from Högskolan i Gävle/Energisystem

   Author : Alejo Louro; [2018]
   Keywords : snow; snowmaking; snow making; snowmaker; snow management; climate change; snow production;

   Abstract : A research on analysing the feasibility and the benefits obtained from the utilisation of the heat surplus from temperature independent snowmaking systems is proposed. The interest of this research relies on the fact that it is a way of making it viable both economically and environmentally, to use these systems, which are the solution for snow scarcity due to global warming.

5. 4. Numerical Simulation of Diurnal Planetary Boundary Layer Effects and Diurnal Mountain-Wind Effects

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Robin Isaksson; [2016]
   Keywords : Numerical weather prediction; planetary boundary layer; mountain-wind system; WRF; Numerisk väderprognos; atmosfäriskt gränsskikt; bergvindsystem; WRF;

   Abstract : The Weather Research and Forecasting Model was used to study its accuracy and representation in modelling a study area within a complex wind system as well as the effects on the model when using different input data and physics schemes. The complex wind system consists of diurnal mesoscale effects from the nearby Pyrenees mountain range and diurnal effects from the planetary boundary layer. READ MORE
