(MDPI AG, 2018-07-04)It is of vital importance that nature-based tourist destinations maintain their natural resources in a sustainable way. Nature and wilderness are the main attractions for tourism in Iceland. The Central Highlands are uninhabited with little visible ... -
(Agricultural University of Iceland, 2016-06)The Icelandic goat is an indigenous breed, descendant of goats brought to Iceland by Nordic and Celtic settlers in the 9th century (Adalsteinsson 1981). The population is estimated to have been below 1000 individuals for centuries and critically ...

(Public Library of Science (PLoS), 2005-03-15)Lack of knowledge about how regulatory regions evolve in relation to their structure–function may limit the utility of comparative sequence analysis in deciphering cis-regulatory sequences. To address this we applied reverse genetics to carry out a ...

(Agricultural University of Iceland, 2019)Fungal distribution in a liverwort-based biocrust was examined at different depths (0, 5 and 20 mm) by direct counting using both light and fluorescence microscopy. The DNA-based taxonomic composition of fungi was also determined and differences between ...
-
(Oxford University Press (OUP), 2019-12-04)Fisheries produce large amounts of waste, providing food subsidies for scavengers. Discards influence seabird movement, demography and community structure, but little is known about seabird-fishery interactions where discarding is banned. Here, we ...

(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-04-26)The four morphs of Arctic charr (Salvelinus alpinus) in Lake Þingvallavatn, Iceland, which differ in many phenotypic traits related to morphology, life history, and feeding ecology, are believed to have evolved locally within the lake after the retreat ...
-
(Genetics Society of America, 2019-09-01)The pleurocarpous feather moss Pleurozium schreberi is a ubiquitous moss species which plays a fundamental role in many terrestrial ecosystems, for instance within the boreal forest, the Earth’s largest terrestrial biome, this species plays a significant ...
-
(MDPI AG, 2018-06-26)Geotourism is one of the newest concepts within tourism studies today. The popularity of geotourism has likewise grown rapidly over the past few decades. This rapidly growing popularity and the growing body of research on geotourism create the need for ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2020-10)Climate change constitutes one of the most pressing challenges faced by tourism today. Tourism research on climate-induced environmental changes has contributed to an increase in knowledge about adaptation during the last decade. Despite a general ...
-
(Wiley-Blackwell, 2017-01)Coastal marine Vibrio cholerae populations usually exhibit high genetic diversity. To assess the genetic diversity of abundant V. cholerae non-O1/non-O139 populations in the Central European lake Neusiedler See, we performed a phylogenetic analysis ...
-
(Wiley-Blackwell, 2017-05-09)Macrobrachium rosenbergii, the giant freshwater prawn, is an important source of high quality protein and occurs naturally in rivers as well as commercial farms in South and South-East Asia, including Bangladesh. This study investigated the genetic ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2016-12)For most of the Holocene the main driver of vegetation and environmental change in Iceland was climate, although intermittent volcanic events had short term impacts. This changed with the Norse colonisation in the late 9th century AD, from when land ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2019-05)Sponges (phylum Porifera) are considered one of the oldest extant lineages of the animal kingdom. Their close association with microorganism makes them suitable for studying early animal-microbe symbiosis and expanding our understanding of host-microbe ...
-
(Public Library of Science (PLoS), 2016-11-21)Populations of rock ptarmigan (Lagopus muta) in Iceland fluctuate in multiannual cycles with peak numbers c. every 10 years. We studied the ptarmigan-parasite community and how parasites relate to ptarmigan age, body condition, and population density. ...
-
(MDPI AG, 2020-06-20)The Arctic Council is an intergovernmental forum promoting cooperation, coordination and interaction among Arctic states, indigenous communities, and peoples on issues of common importance. The rising geo-political importance of the Arctic and the onset ...
-
(Cold Spring Harbor Laboratory, 2019-07-30)Detailed modeling of a species’ history is of prime importance for understanding how natural selection operates over time. Most methods designed to detect positive selection along sequenced genomes, however, use simplified representations of past ...
-
(MDPI AG, 2019-08-21)With growing tourism in natural areas, monitoring recreational impacts is becoming increasingly important. This paper aims to evaluate how di_erent trampling intensities a_ect some common Icelandic plant communities by using digital photographs to ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Life and Environmental Sciences, 2016-09)Very little is known on the ecosystem impacts of emissions from geothermal power plants. The emissions, comprising mainly of non- condensable gases (NCGs) i.e. carbon dioxide, hydrogen sulphide, methane and trace elements such as arsenic, ...
