(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Genes of the major histocompatibility complex (MHC) are crucial for adaptive immunity, and theory predicts that the optimal number of alleles is intermediate rather than maximal. Support for such an intermediate optimum ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Purpose Treelines and forest lines (TFLs) have received growing interest in recent decades, due to their potential role as indicators of climate change. However, the understanding of TFL dynamics is challenged by the complex ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)This contribution presents new U-Pb geochronological data and attempts to elucidate the complex evolution history of various garnet types identified from two kimberlite pipes in the Wafangdian diamond mining district, ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)In recent years, the field of sexual selection has exploded, with advances in theoretical and empirical research complementing each other in exciting ways. This perspective piece is the product of a “stock-taking” workshop ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We use natural language processing (NLP) to retrieve location data for cheilostome bryozoan species (text-mined occurrences (TMO)) in an automated procedure. We compare these results with data combined from two major public ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Interspecific competition is thought to play a key role in determining the coexistence of closely related species within adaptive radiations. Competition for ecological resources can lead to different outcomes from character ...
-
(Journal article / Tidsskriftartikkel / SubmittedVersion, 2018)Five hydrocarbon seep carbonate structures in the upper part of the Slottsmøya Member (Agardhfjellet Formation) in central Spitsbergen have been sampled and processed for foraminifera. The carbonates have been found to ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Microporella Hincks, 1877 is one of the most diverse genera of cheilostome bryozoans, containing more than 150 named species. Distributed globally since the early Miocene, the majority of species of Microporella have ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Site‐occupancy modelling is widely used in ecology for understanding species distribution, habitat‐use and community changes but its application is still limited in paleoecology, where incomplete detection is also routine. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Background: The genus Aloe has long been known for its use in healthcare and cosmetics. In Tanzania, overexploitation is threatening some Aloe species with extinction and yet, little has been documented on the abundance ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Ethnopharmacological relevance: This study is the first ethnobotanical survey focusing on the herbal medicines traditionally used by the nomadic community of the Algerian steppe, identifying new medicinal plants and uses ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Ethnopharmacological relevance: More than 15,000 angiosperm species are dioecious, i.e., having distinct male and female individual plants. The allocation of resources between male and female plants is different, and also ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)The resin of Canarium strictum Roxb. is used for rheumatism and asthma; the bark is used as a mosquito repellent. The major compounds in the resin are triterpenoids, but as no studies have been performed on the bark, this ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Thermal melanism theory states that dark-colored ectotherm organisms are at an advantage at low temperature due to increased warming. This theory is generally supported for ectotherm animals, however, the function of colors ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Recent global warming affects species compositions at an unprecedented rate. To predict climate-induced changes in species assemblages, a better understanding of the link between species occurrence and climate is needed. ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The extensive spatial and temporal coverage of many citizen science datasets (CSD) makes them appealing for use in species distribution modeling and forecasting. However, a frequent limitation is the inability to validate ...
-
(Doctoral thesis / Doktoravhandling, 2018)Despite the similar function of all sperm cells – to fertilise the egg – there is extraordinary diversity in sperm shape and length across taxa. This thesis aims to improve our understanding of how this diversity has ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Background Female promiscuity is highly variable among birds, and particularly among songbirds. Comparative work has identified several patterns of covariation with social, sexual, ecological and life history ...
-
(Doctoral thesis / Doktoravhandling, 2011)Genetic variation is a prerequisite for evolution. The present thesis examines how genetic diversity arises and is maintained. The thesis can be divided into two subprojects, addressing neutral and functional genetic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Allometric scaling describes the relationship of trait size to body size within and among taxa. The slope of the population-level regression of trait size against body size (i.e. static allometry) is typically invariant ...
