(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)As many ecosystems are under increasing pressure from invasive species, habitat degradation, overgrazing and overharvesting, pollution, and climate change, dietary niche monitoring is gaining importance. The Malai Mahadeshwara ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Sperm cells are variable both within and among species. To be able to accurately measure sperm cells and understand their function, it is important that sperm cells are preserved in a manner that maintains their ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Anthropogenic inputs of nutrients and organic matter are common in tropical lowland rivers while little is known about the pollution-induced changes in oxygen availability and respiratory performance of ectotherms in these ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Molecular-based monitoring relying on environmental DNA (eDNA) detection became routinely used around the world in the last few years, especially in aquatic environments. The large potential and increasing applications of ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Shrub expansion in high latitudes is a widely observed response to climate change. Extensive evidence has shown that shrub expansion can lead to positive feedbacks to the regional climate. In this study we evaluate the ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Abstract Stochastic simulation is a key tool in population genetics, since the models involved are often analytically intractable and simulation is usually the only way of obtaining ground-truth data to evaluate ...
-
(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 ...
