(Wiley, 2018-11-26)Gene expression during development shapes the phenotypes of individuals. Although embryonic gene expression can have lasting effects on developmental trajectories, few studies consider the role of maternal effects, such as egg size, on gene expression. ... -
(Public Library of Science (PLoS), 2019-10-02)Crangonyx islandicus is a groundwater amphipod endemic to Iceland, considered to have survived the Ice Ages in subglacial refugia. Currently the species is found in spring sources in lava fields along the tectonic plate boundary of the country. The ...

(Informa UK Limited, 2019-01-08)The complete mitogenome of Buccinum undatum obtained from transcriptome analysis is presented here. The mitogenome is 15,265 bp in length and comprises 13 protein-coding genes, 2 ribosomal subunit genes, and 22 transfer RNAs. The complete genome was ...

(Oxford University Press (OUP), 2019-04-25)Ostracods in Icelandic freshwaters have seldom been researched, with the most comprehensive record from the 1930s. There is a need to update our knowledge of the distribution of ostracods in Iceland as they are an important link in these ecosystems as ...

(Wiley, 2019-06-19)A major goal of evolutionary science is to understand how biological diversity is generated and altered. Despite considerable advances, we still have limited insight into how phenotypic variation arises and is sorted by natural selection. Here we argue ...

(PAGEPress Publications, 2018-05-31)In 1937, S.L. Tuxen studied the animal community of hot springs in Iceland, and classified springs according to their relative temperature into cold, tepid, and hot. Eighty years after Tuxen’s study, we revisited some of the hot springs in Skagafjörður, ...

(Wiley, 2018-02-28)Streams fluctuate in water flow because of natural (e.g., rain) and human‐induced events (e.g., hydropeaking). Magnitude, frequency, and predictability of these events can have drastic consequences for fish populations. We studied how rapid modifications ...
-
(Wiley, 2018-04-10)Geographical patterns in morphology can be the result of divergence among populations due to neutral or selective changes and/or phenotypic plasticity in response to different environments. Marine gastropods are ideal subjects on which to explore these ...
-
(PeerJ, 2018-02-07)Phenotypic differences between closely related taxa or populations can arise through genetic variation or be environmentally induced, leading to altered transcription of genes during development. Comparative developmental studies of closely related ...
-
(Wiley-Blackwell, 2018-01-03)The early stages of intraspecific diversity are important for the evolution of diversification and speciation. Early stages of diversification can be seen in individual specialization, where individuals consume only a portion of the diet of the population ...

Plio-Pleistocene phylogeography of the Southeast Asian Blue Panchax killifish, Aplocheilus panchax (Public Library of Science (PLoS), 2017-07-25)The complex climatic and geological history of Southeast Asia has shaped this region’s high biodiversity. In particular, sea level fluctuations associated with repeated glacial cycles during the Pleistocene both facilitated, and limited, connectivity ...

(Viðskiptafræðideild og hagfræðideild Háskóla Íslands, viðskiptafræðideild Háskólans í Reykjavík og Seðlabanki Íslands., 2016)Í þessari grein er skoðað hvað einkenni þróun fyrirtækja í hestamennsku (e. horse industry) á Íslandi og hverjar séu helstu ástæður þess að hestamennska sem áhugamál eða lífsstíll er þróuð yfir í fyrirtæki. Auk þess er rýnt í það hver sé þáttur ...

(F1000 Research, Ltd., 2016-12-02)Species and populations with parallel evolution of specific traits can help illuminate how predictable adaptations and divergence are at the molecular and developmental level. Following the last glacial period, dwarfism and specialized bottom feeding ...

(Háskóli Íslands, 2016-12-16)Mikill munur er á menntunarstigi þjóðarinnar eftir landshlutum. Árið 2011 höfðu þannig 38% íbúa höfuðborgarsvæðisins á aldrinum 25–64 ára lokið háskólaprófi en 21–23% í flestum öðrum landshlutum. Þessi munur skýrist að hluta af takmörkuðu framboði ...

(ELSEVIER SCIENCE BV, 2015-11-01)Every year, numerous studies are published that compare the effects of different factors on the growth of aquaculture fish. However, comparatively little attention has been given to the experimental designs of these studies - in how many rearing units ...
