1. Riparian buffer zones in agricultural landscapes : Their status today and their future as an ecological tool in Sweden
Master-uppsats, Karlstads universitetSammanfattning : The application of intensive farming and cultivation practices, resulting in large-scale modification of the hydrology of streams and rivers and of the natural vegetation, has increased the need to find ways to mitigate the negative impact of this habitat degradation. Suitable design and creation of riparian buffer zones in agriculture areas, is by many considered the best remedial measure. LÄS MER
2. Effects of native freshwater mussels and leaf debris on benthic macroinvertebrate abundance and diversity : A field experiment with Margaritifera margaritifera in Vasslabäcken, Örebro county
Master-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)Sammanfattning : Organisms that are part of complex ecosystems interact not only with other organisms but also with their environment, affecting ecosystem functions. In aquatic ecosystems filter feeders affect ecosystem functioning by transferring energy and nutrients from the water to the benthos. LÄS MER
3. Deforestation patterns and hummingbird diversity in the Amazon rainforest
Kandidat-uppsats, Stockholms universitet/Institutionen för naturgeografiSammanfattning : In recent decades expanding land-use change has caused extensive deforestation of the tropical rainforestinducing large-scale transformation of the landscape patterns across the South American continent. Landscapechange is a modification process of the natural forest cover into fragments which generate various ecologicalimpacts. LÄS MER
4. Hur påverkar död ved bottenfaunas täthet, sammansättning och diversitet? : Ett experiment i semi-naturliga bäckar
Kandidat-uppsats,Sammanfattning : Mänsklig störning i form av modifiering av skogsbäckar och dess strandzoner har lett till en minskad mängd död ved i skogsbäckarna. Detta har lett till en rad förändringar i skogsbäckars fysiska struktur och egenskaper som därmed påverkat deras lämplighet som habitat för olika bottenfaunaarter. LÄS MER
5. Anthropogenic Disturbance in Nocturnal Primates & Conservation Perception in Zaraninge Forest, Tanzania
Master-uppsats, Lunds universitet/Examensarbeten i biologiSammanfattning : Galagos are an understudied family of primates which inhabit much of Sub-Saharan Africa, some of which are potentially at risk. The coastal forests of East Africa are home to many galagos, however this habitat is under threat from an increasing human population seeking timber, charcoal and land for agriculture, amongst other pressures.
